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.
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.

(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.

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.
Compare and contrast the advantages and disadvantages of wind power and geothermal power
Answer:
An Overview of Geothermal Pros and Cons:
Pros Cons
This energy source is more environmentally friendly than conventional fuel sources. The largest single disadvantage of geothermal energy is that it is location specific.
A source of renewable energy. Gases are released into the atmosphere during digging.
The number of exploitable geothermal resources will increase with ongoing research and development in the industry. Geothermal energy runs the risk of triggering earthquakes.
A sustainable source of energy as its always available unlike wind and solar. Expensive resource to tap into, with high upfront costs ranging from around $2-$7 million for a plant with a 1 megawatt capacity.
A reliable source as its easier to predict the power output from a geothermal plant with a high degree of accuracy. Energy fluid needs to be pumped back into the underground reservoirs faster than it is depleted. Management is required to maintain sustainability.
No fuel is required.
Increase in exploration meaning that new technologies are being created to improve the energy process.
Pollution levels are much lower compared to fossil fuels.

Answer:
a) Particular codons are generated in predictable ratios with random RNA polymers containing specific ratios of different nucleotides.
b) Poly(A) RNA directs the synthesis of only polylysine in vitro.
d) The codon table was completed by using RNA polymers of defined sequences.
Explanation:
A polynucleotide molecule is defined as the biopolymer which is composed of thirteen nucleotide monomers or more monomers which is covalently bonded in the chain.
While using the synthetic polyneuclitide in the cracking of the genetic code, the translation of a [tex]\text{poly(A) RNA tail}[/tex] that results in synthesis of the poly-lysine in the lab.
Some of the particular codons are produced by some specific ratios of a different nucleotides. This can be present in the different RNA polymers. Codon table includes the RNA polymers that contains nucleotides in some specific ratios.
Thus, the options (a), (b) and (d) are correct.

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.

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.
A. Coats guard hairs to improve their informance
B. Usually opens up into a hair follicle
C. Simple, coiled, tubular glands
D. Secretes earwax
E. Coats the scalp hair with oil
F. Blockage and infection can cause pimples
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.
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
