Answer:
1) sedimentary
Explanation:
Sedimentary rocks are formed by the accumulation and subsequent compression of sediments (i.e., minerals and once-living organisms known as fossils) on the Earth's surface. Almost all fossils are found within sedimentary rocks. Some examples of sedimentary rock that contain fossils include limestone, mudstone and shale. Rock layers are known as strata. The oldest layers containing the once-living organisms (which were fossilized as they formed) are found at the bottom, while the youngest layers are found at the top.
A traumatic injury to the inferior angle of the mandible severs the hypoglossal nerve. Which of the following muscles would be affected?
a. Geniohyoid
b. Mylohyoid
c. Genioglossus
d. Stylohyoid
The muscle that would be affected is the Genioglossus. That is option C.
The hypoglossal nerve is the also known as cranial nerve XII.
This nerve arises from the nuclei in the medulla oblongata.
They supply:
the muscles of the tonguemuscles surrounding the hyoid bone andcontribute to swallowing and speech.The muscles of the tongue includes
genioglossus, hyoglossusstyloglossus, and palatoglossusThe genioglossus is a flat triangular muscle that forms the base by which the tongue is attached.
Since the hypoglossal nerve supplies the the tongue muscle (genioglossus), it would be must affected when mandible severs the hypoglossal nerve.

Which of the following is a disadvantage of planting a variety of crops rather than a monoculture?
A.) It is more likely to lead to crop failure.
B.) It can decrease farming efficiency and profit.
C.) It can promote biodiversity in ecosystems.
D.) It can lead to an increased risk of parasite infection.
Answer:
D.) It can lead to an increased risk of parasite infection.
Explanation:
Monoculture is a system of farming or cropping whereby a single crop is planted on a given area of land. The opposite of this system of farming is known as multiple cropping, where a variety of crops are cultivated.
One disadvantage of planting a variety of crops over a single crop in monoculture is that it increases the risk of parasite/pest attack on the crops. Parasites and pest can easily shift to the variety of crops planted in the farm.

what are the three strategies that the community could place to work with governmental structures to stop illegal dumping
Answer:
Illegal Dumping has gotten out of hand. According to the Los Angeles County Public Works, “People usually dump illegally to avoid collection and disposal fees, or because they believe proper disposal is just ‘too much trouble’.” This is very unfortunate for our communities who receive the negative consequences of higher taxes for cleanup, environmental hazards, and a breeding ground for rats.
The cost of a one-time cleanup and detoxing of an area can cost thousands of dollars. But to leave the mess is just not an option. The best option is to stop the illegal dumping before it happens, preventing the cost of cleanup, preventing the chemicals and toxins from entering the ground water, and preventing the rats and mosquitoes from breeding. The best areas to live are communities that care about their community! So, what can a community do to prevent illegal dumping?
Here are some key points to help deter illegal dumping:
Educate the public through the schools and through community awareness groups about the costs, chemical hazards and dangers incurred by illegal dumping
Create safe, public-friendly waste disposal options and advertise them
Create laws that impose stiff fines for the perpetrators and advertise these stiff fines
Use Illegal Dumping Cameras to catch the perpetrators in the act
Use Social Media to ask the public to identify the perpetrators
Follow through with quick clean up
These steps will invite the citizens to be involved and help deter the criminal activity of illegal dumping within your community.

Reproduction is important for every type of living thing. Without it, species would die out. To ensure their survival, animals have developed unique adaptations to improve their chances of reproducing. Behavioral adaptations are behaviors an organism performs to help it survive. Structural adaptations are physical features that help an organism survive.
The image below shows two peacocks. The male peacock is large and brightly colored. The female peacock is not as colorful. The size and color of the male's feathers attract females. This is an example of a structural adaptation intended to help with reproduction. Another structural adaptation is when male deer grow large antlers to attract females. Animals also use behavioral adaptations to attract mates. For example, male frogs sing to attract females and male spiders dance to attract females.
Plants also have adaptations to help with reproduction. While animals use behavioral and structural adaptations to improve reproduction, plants only use structural adaptations. For example, brightly colored flowers attract butterflies. Certain flowers also have nectar or give off an odor to attract insects. Attracting butterflies and other insects is important because they play a role in reproduction by pollination.
Which of the following describes an adaptation that relates to reproduction?
A. Hawks have sharp beak to help them quickly catch their prey
B. Elks attach leaves and grasses to their antlers to help them appear larger
C. Polar bears have white fur to help them blend into their surrounding environment
D. Whales have a thick layer of fat called blubber
Answer:
B. Elks attach leaves and grasses to their antlers to help them appear larger
Explanation:
The above option is the correct answer.
As elks appear larger, it tend to make other male elks to be scared to fight that particular elk for a female elk. Also, the female elk becomes more attracted to larger male elk.
Male elk are known to actually retain their antlers for more than half the year. Such elks do not likely group themselves with other males when they have antlers.
From what you know of tonicity, what can you say about the plant cells and the solutions in the test tubes
Answer:
Tonicity is the relative amount of solutes that is dissolved in solution which determine the direction and level of diffusion.
Explanation:
Tonicity is the relative amount of solutes that is dissolved in solution which determine the direction and level of diffusion. There are three types of tonicity i.e. hypertonic, hypotonic and isotonic solution. If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink due to more solute in the external environment. In an isotonic environment, there is no water movement occurs, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell. due to lower amount of water present inside the cell.

When performing the streak for isolation technique, your result is unexpected: There is only growth obtained in quadrant 1. The growth observed in quadrant 1 is as expected, heavy with no isolated colonies. However, no growth is visible in any other quadrants.
Which of the following errors could explain this unexpected result?
A) The loop did not cross into quadrant 1 when streaking quadrant 2
B) You forgot to flame the loop in between quadrants
C) All of the errors listed here could be responsible for this unexpected result
D) Not enough bacteria was obtained from the starting culture when streaking quadrant 1
Answer:
A) The loop did not cross into quadrant 1 when streaking quadrant 2
Explanation:
The streak for isolation technique is a method used to get isolated bacterial colonies. This technique consists of, in a petri dish with culture medium, where, with the help of an inoculation loop, the bacteria are scratched on one side of the dish. This side is called the first quadrant. This inoculation loop must then cross with the first quadrant and be dragged to the second quadrant, where new lines must be made. This allows a part of the bacteria from the first quadrant to be carried over to the second. The inoculation loop must cross the second quadrant again to inoculate the third quadrant, and so on.
In this case, we can see that for bacterial colonies to grow in all quadrants, it is essential that the loop crosses in the first quadrant to cross out the second quadrant. If not, only the first quadrant will have bacterial colonies.
Answer:
A) The loop did not cross into quadrant 1 when streaking quadrant 2
Explanation:
There are many different techniques to isolate bacteria populations. Using solid media such as agar, you can perform the streak for isolation technique.
What you want to do by using this technique is to get an isolated colony of the bacteria of interest. And to get it, you need to dilute a sample or inoculum of bacteria as much as possible by streaking it. Every time you do it, you take fewer amounts of cells from the original sample, separating them each time more, to the point of having only one single cell apart by a few millimeters from another cell. The isolated cell divides and forms a new pure colony.
So basically, you need to imaginary divide the agar plate into four quadrants.
You sterilize the loop carefully and take a sample of bacteria, trying to get the smallest amount of inoculum. You will apply the loop with the sample in quadrant one and spread it. You close the plate and turn it, placing the second quadrant in front of you. You sterilize the loop again on the flame and let it cool. You perform the same motion in quadrant two but carefully touching the edge of quadrant one, so you can take some of the cells that you have already spread on it. Once you spread quadrant two, you close the plate and turn it again, so quadrant three is in front of you. You sterilize the loop again on the flame and let it cool. You perform the same motion in quadrant three but carefully touching the edge of quadrant two. Close and rotate the plate. You sterilize the loop and repeat the same motion in the last quadrant. Close the plate and take it to incubation. Finally, you put the loop on the flame for the last time.The importance of extending the streaks into the anterior quadrant is to take a few cells from there and to spread them in the following quadrant. In this way, you are diluting the original inoculum, and separating the cells each time more. The fourth quadrant should have a few isolated cells that will reproduce and form a pure colony. If you do not touch the anterior quadrant while streaking, you will not have any cell in the quadrant, and you will not observe any colony after the incubation. The importance of sterilizing the loop every time you change the quadrant is to avoid contamination with other species. If you do not flame the loop, the result will be too many colonies of different species, probably touching themselves, in each quadrant.Consider sebaceous and ceruminous glands. Then, click and drag each label into the appropriate category based on whether it pertains to sebaceous glands, ceruminous glands, or both.

1. Sebaceous
2. Ceruminous
Answer:
A. Ceruminous
B. Sebaceous
C. Ceruminous
D. Ceruminous
E. Sebaceous
F. Sebaceous
Explanation:
Ceruminous glands are modified sweat glands located subcutaneously in the cartilaginous two-thirds of the external auditory canal. Ceruminous glands produce together with sebaceous glands the cerumen (i.e. earwax), which protects the ear canal against physical damage and/or microbial infections. On the other hand, sebaceous glands are glands in the skin that secrete sebum, an oily, waxy substance that lubricates the hair and skin of mammals. These glands (sebaceous) are affected by sex hormones like testosterone that enlarges the glands due to the increased cell proliferation rate and estradiol, which reduces the size of the glands due to the accelerated cell breakdown. Sebaceous glands are holocrine glands in which secretions are produced in the cytoplasm of the cells and then they are released by the rupture of the plasma membrane, while ceruminous glands are apocrine glands where the accumulated secretion is pinched off with a portion of the cell.
What does a chromosome consist of?
A. Tightly wound DNA only.
B. Loosely dispersed DNA and proteins.
C. Tightly wound DNA and proteins.
D. Loosely dispersed DNA.
Answer:
C
Explanation:
So, there are 2 different forms that DNA can be found in.
The more common form, where the DNA is loosly scattered.
There is a less common form, however, only found during cell division, which is a compacted form. The DNA is tighly wound in this case.
In the case of chromosomes, DNA is tightly pakced, and not loose.
Now, do they are do they not have protiens?
Well, heres another question, how does the DNA get compacted?
It has to wrap around histone protiens.
The logn strands of DNA wrap around many histone protiens, until the full length of DNA has been compacted.
So to answer the question, yes, there are protiens found in chromosomes(specificly histone).
This means the answer must be C, since chrosomes are both tightly bound, and contain protein.

what are the characteristics of normal cells and cancerous cells?
Normal cells stop growing (reproducing) when enough cells are present. For example, if cells are being produced to repair a cut in the skin, new cells are no longer produced when there are enough cells present to fill the hole (when the repair work is done).
In contrast, cancer cells don’t stop growing when there are enough cells present. This continued growth often results in a tumor (a cluster of cancer cells) being formed.

How much stronger is a magnitude 8 earthquake than a magnitude 5 earthquake?
A. 1000
B. 30
C. 3
D. 10
Answer:
A. 1000
Explanation:
The Richter scale is a scale of numbers used to measure the magnitude of an earthquake, which is based on the size of its seismic waves. This scale indicates a number to quantify the total seismic energy released by an earthquake. The Richter magnitude scale is a base-10 logarithmic scale, thereby a difference of one (1) point in the scale of magnitude corresponds to a 10-fold increase in amplitude. For example, based on the Richter scale, a magnitude-8 earthquake is 100 times greater than a magnitude-6 and 1000 times greater in amplitude than a magnitude-5.

1 point
(a). soft substrates
(b) hard substrate
(c) dry mud
(d) rocks
Answer:
(a). soft substrates
Explanation:
Mobile organisms can be measured by both direct and indirect methods. Direct methods may involve observing the actual behavior (e.g., scoring via timing). Moreover, indirect methods are those where the technique used depends on the species being examined, collecting information such as through recording of tracks in the soft substrate (e.g., mud, sand, snow), presence of fur/feathers, droppings (mammals), etc. For example, indirect observation of insects may involve the determination of exoskeletons, sounds, etc.
