What happens when volcanoes release greenhouse gases into the atmosphere?
Answer:
a. the climate gets warmer...
Explanation:
When volcanoes release greenhouse gases into the atmosphere, global warming is due to the greenhouse effect.
What do you mean by the Greenhouse effect?The Greenhouse effect may be defined as the phenomenon of keeping the earth warm due to the presence of certain gases in the atmosphere.
Greenhouse gases like carbon dioxide, Methane, and Nitrous oxide allow the solar radiations to enter but prevent the escape of heat radiations of longer wavelength.
Due to this, the gradual and continuous increase in the average temperature of the earth's surface occurs, a phenomenon known as global warming.
Therefore, when volcanoes release greenhouse gases into the atmosphere, global warming is due to the greenhouse effect.

Answer:
A Detritivore
Explanation:
A Detritivore is a heterotrophic organism that feeds on dead plant and animal materials. They could also feed through coprophagy which is nutrition obtained by feeding on feces. Worms that dwell on the soil, insects, and mollusks are examples of detritivores. Detritivores can also be found residing in aquatic environments. Crabs and Lobsters are examples of these organisms.
Detritivores have no teeth. So, they tend to suck in their food, and this food, through peristaltic actions, moves directly into the digestive tract where it is acted upon by digestive enzymes. From the observations, I made about the organism at the mudflat at the ocean, I can conclude that it is a detritivore.

The lithosphere is the rigid part of the earth, consisting of the crust and upper mantle.
The incidence of phenylketonuria (PKU), an autosomal recessive genetic disorder, is approximately 1 in 4,500 in Ireland. Assuming Hardy-Weinberg equilibrium, what is the probability that an Irish female, who is phenotypically normal with no family history of PKU, and an Irish male, who like his parents does not have PKU, but does have a sister with PKU, will have a child with PKU?
Answer: Probability: 0%
Explanation:
Hardy-Weinberg establishes that the genetic composition of a population remains in equilibrium as long as no natural selection or other factors act and no mutations occur. This means that the children of this couple will inherit the genes of the parents.
The woman is phenotypically normal with no family history of PKU, this mean that probably there are no affected (recessive) alleles in her family. In an autosomal recessive disorder, both copies of the gene in each cell are recessive. Therefore, her genotype will be AA with A being the dominant and normal allele. As for the Irish man, his sister does have PKU, which means her genotype is aa. So, she must have received a defective allele from each parent. Then the parents' genotypes are both Aa (heterozygous, only one allele affected as they are healthy). So, we know that the Irish man does not have the disease (he can't be aa), but he could be Aa (having inherited a normal allele from one parent, and an affected one from the other parent) or AA (having inherited both normal alleles from each parent).
Then we have two possible punnetts square to do: AA (the Irish woman) and AA (he Irish man); or AA (woman) and Aa (man).
In the attached figure both punnetts squares are shown. The first punnett square (AA x AA) shows that 100% of the offspring will be AA (this means, the phenotypic ratio is also 100% not affected and non-carrier). The second punnett square (AA x Aa) shows that 50% will be AA (healthy and non-carrier) and 50% will be Aa (heterozygous, healthy and carrier) But since it is an autosomal recessive disease, a single affected allele is not enough to develop the disease. So in neither case is there a chance of having a child with PKU.
Only ------ percent of the food eaten is turned into its own body.
Answer:
10%
Explanation:
there is a the rule that only 10% of the energy is transferred from one trophic level to the other.
this means that only 10% of the food an organism eats is passed onto the next organism. eg only 10% of the energy in a plant is transferred to a rabbit that eats the plant. After that if a wolf eats the rabbit only 10% of the energy of food will pass on to the wolf.

If capeland switches from producing 0 watermelons to producing 18 million tons of watermelons, what does it give up?
Answer:
Attached to this solution is an image of the complete question and data.
The correct answer is:
6 million pairs of shoes
Explanation:
From the diagram attached to this answer, the following data can be gotten:
Watermelons shoes
(Millions of tonnes) (Millions of pairs)
0 15
8 14
14 12
18 9
20 5
21 0
From the pattern of the data shown above, we notice that as the production of one commodity increases, the other is given up (decreases)
Therefore, to find how much shoes are given up if Capeland switches from 0 watermelons to 18 million tons of watermelon, we will find the difference between the number of shoes produced at 0 and at 18 million tons of watermelon
at 0 watermelon; shoes = 15 million pairs
at 18 million tons of watermelon; shoes = 9 million pairs
Therefore, number of shoes given up = 15 - 9 = 6 million pairs
Hence, 6 million pairs of shoes are given up tp increase production of watermelon from 0 to 18 million tons
briefly outline how cell theory has developed over the past 400 years
Explanation:
The cell theory, or cell doctrine, states that all organisms are composed of similar units of organization, called cells. The concept was formally articulated in 1839 by Schleiden & Schwann and has remained as the foundation of modern biology. The idea predates other great paradigms of biology including Darwin’s theory of evolution (1859), Mendel’s laws of inheritance (1865), and the establishment of comparative biochemistry (1940).
First Cells Seen in Cork
While the invention of the telescope made the Cosmos accessible to human observation, the microsope opened up smaller worlds, showing what living forms were composed of. The cell was first discovered and named by Robert Hooke in 1665. He remarked that it looked strangely similar to cellula or small rooms which monks inhabited, thus deriving the name. However what Hooke actually saw was the dead cell walls of plant cells (cork) as it appeared under the microscope. Hooke’s description of these cells was published in Micrographia. The cell walls observed by Hooke gave no indication of the nucleus and other organelles found in most living cells. The first man to witness a live cell under a microscope was Anton van Leeuwenhoek, who in 1674 described the algae Spirogyra. Van Leeuwenhoek probably also saw bacteria
The cell theory, states that all organisms are composed of similar units of organization, called cells.
What is cell theory?The concept of cell theory was in 1839 by Schleiden & Schwann which leads the foundation of modern biology. Cell theory states that every cell is generated from another preexisting cell.
This idea makes the great revolution in biology including Darwin’s theory of evolution (1859), Mendel’s laws of inheritance (1865), and the establishment of comparative biochemistry (1940).
Schleiden & Schwann propose every organism is composed of the cell, which is the basic unit of life and each cell comes from the preexisting cell, and each cell produces a progeny which is similar to its parent cell.
Therefore, cell theory states the existence of the cell in the organism.

The question is incomplete,below is the complete question.
Mr. B has been transferred to your floor to wait and see whether the chest tube allows his lungs to completely re-expand. But when he arrives, he is in severe respiratory distress. He says "I felt better before I came into the ER! Is this tube doing anything?"
You tell the Clinical Nurse Specialist (CNS). As the two of you move him into the bed, you notice that his chest tube bottle is lying on its side on the gurney, with air going into it. When you point this out to the CNS, she immediately grabs the bottle and sets it upright on the floor. You see air start bubbling through the fluid right away. "That was the problem!" she says. "They lost the water seal, and air was going into his chest from the bottle. You would not believe how many times that happens on transport." When you examine Mr. B, you have trouble detecting his lung sounds on the left. Even stranger, his apical heart sound is in the wrong place - it is over toward the right side of his chest. His respiration rate and heart rate are both increased, and he is struggling to breathe. "Let's give him a little oxygen. He'll be a lot better in a half-hour," says the CNS. "Check back on him."
QUESTION - Why would accumulation of air in his pleural space cause his heart sounds to be in the wrong place?
Accumulation of air in Mr B pleural space will cause his heart sound to be heard in the wrong place because the left side is his chest is being filled up with air making the organs in his chest to to be pushed over to the right side.

Scientists are able to reproduce certain plants and animals by cloning them in laboratories. The diagram shows the steps of cloning using tissue cultures. Do you think cloning is a form of asexual reproduction? Explain your answer using evidence from the diagram
Answer:
Yes.
Explanation:
Yes, cloning is a form of asexual reproduction because there is no fusion of sperm and eggs takes place. the animal which is formed from this process is identical of that organism because it is produced from the tissue of that single animal. in 1996, first mammal is produced from cloning was sheep named dolly at the Roslin Institute in Scotland. In cloning, the egg is taken from female organism and remove the nucleus from the egg then the desired organism cell is taken and fuse with the nucleus with the help of electricity. Then implant this embryo in the body of first organism from where egg is taken and after that the embryo turns into a baby, this process is called cloning.
Answer:
Yes, cloning is a form of asexual reproduction. The diagram shows that new plants form from a single parent plant, which means that the offspring are genetically identical to the parent.

Answer:
Water, high specific heat capacity
Explanation:
The temperature fluctuations are relatively small in Jameson city because takes water longer to heat up and cool down due to its high specific heat capacity because water has high heat capacity that is it absorb alot of heat before it start to get hot. takes more energy to increase the temperature of water compared to other substances which help to regulate extremes in the environment.
Water surrounding cities take longer to heat up and longer to cool down so cities that are near the oceans will tend to have less change and less extreme temperatures compared to inland cities.

Natural selection states that complex organisms evolved through random mutations alone. True or False?
Answer:
False.
Explanation:
This statement is false because organisms don't evolve - populations do. New gene variants (i.e., alleles) are produced by random mutation, and over the course of many generations, natural selection may favor advantageous variants, causing them to become more common in the population. However, because mutation rates are low relative to population growth in most species, mutation alone doesn't have much of an effect on evolution.

2) Micah and Taylor investigate the effect of tap water and spring water on the growth of plants.
They grew two plants of the same type and size in separate containers. Every three days, they
added the same amount of tap water to one plant and the same amount of spring water to the
other. Describe an action that would best improve the reliability of their results?
Answer:
To improve the reliability of the results, the nutritional component of each category of water must be tested and recorded.
Second, the experiment should be carried out under greenhouse conditions.
The above actions will afford more control. When an experiment is controlled, it means that except for the dependent variable, all other variables are kept constant by the scientist.
By performing the experiment under greenhouse conditions, the kind of water the plants receive, temperature and other biotic actors are kept within measurable limits thus increasing the reliability of the results.
