Mary Anning reconstructed the fossil skeletons of many animals new to science. During her studies, she discovered that some species have become extinct.
Which of the following is one main reason a species becomes extinct?
A. overproduction
B. increased variation
C. decreased competition
D. climate change
Answer:
Hello There. The correct answer is D. Climate change.
Because it shows that Anning continued to support herself selling fossils. Her primary stock in trade consisted of invertebrate fossils such as ammonite and belemnite shells, which were common in the area and sold for a few shillings. Vertebrate fossils, such as ichthyosaur skeletons, sold for more, but were much rarer.

Examine the diagram of the carbon cycle shown above. Through which of the following processes is carbon removed from the atmosphere?
Answer: photosynthesis
Carbon dioxide is naturally removed from the atmosphere by photosynthesis, and trees are particularly skilled at storing the carbon that is removed from the atmosphere by photosynthesis.
What processes is carbon removed from the atmosphere?Respiration and photosynthesis are polar opposites of one another. Through photosynthesis, CO2 is taken from the atmosphere and exchanged for O2. During respiration, O2 is taken from the surrounding air and replaced with CO2. However, none of these processes are in balance.
Plants use photosynthesis to transfer atmospheric carbon into the biosphere and transport it up the food chain. They make sugar molecules by chemically combining water's hydrogen and oxygen with carbon dioxide using energy from the sun.
Therefore, Plants open small pores on the surfaces of their leaves during photosynthesis in order to absorb carbon dioxide from the atmosphere and create their own sustenance.

In what ways did Charles Lyell impact Charles Darwin’s theory of evolution? What type of relationship did Darwin have with Charles Lyell? How did Darwin learn about Charles Lyell's ideas?
Answer:
They both believed that continuous and gradual change is law of nature
Explanation:
Charles Lyell's “Principles of Geology “ encouraged Charles Darwin to think of evolution of living organisms as a slow process just like the slow geological processes taking place since millions of years. As per Charles, the slow and little contribution of continuous geological events shaped the present geological attributes of the earth. Likewise Charles Darwin’s theory of evolution also earmarked accumulated effects of small gradual changes over immense spans of time. They both believed that continuous and gradual change is law of nature.

Carbon-dioxide gas is essential for maintaining life on earth.
Carbon-dioxide present in the atmosphere comes from breathing of animals and volcanic eruption. this carbon-dioxide absorb by the plants (biosphere) in the process of photosynthesis. This carbon-dioxide is incorporated in the soil (geosphere) with the dead bodies of plants and animals and decomposition of these bodies occurs and carbon-dioxide gas again releases in the atmosphere. Carbon-dioxide gas is also dissolved in the water bodies where it is required by the plants for photosynthesis and made food for the marine animals.

As water passes into the guard cells, the pore opens. explain why.
Answer:One of the most important functions of guard cells is to control the closing and opening of the stoma/pores. While the opening of these pores allows water to be released into the environment, it also allows carbon dioxide to enter the cell for photosynthesis (as well as the release of oxygen into the environment).
Explanation:
Answer: guard cells are a pair of cells that surround each of the stoma openings. to open the cells, they have to be triggered by one of many possible environmental or chemical signals. these can include more sunlight or higher than normal levels of carbon dioxide within the cell.
Explanation:
they open to regulate the gas and moisture exchange, hope that this is what you were looking for :)

Explanation:
Two short-tailed Manx cats are bred together. They produce 3 kittens with long tails 5 short tails and 2 without tails. From these results, how do you think tail length in these cats are inherited? Show the genotypes for both the parents and the offspring to support your answer.
Answer and Explanation:
There are three phenotypes, so it seems that this an example of incomplete dominance, with the short tail being the intermediate form between long-tail and no-tail. Incomplete dominance is a condition where neither of the alleles completely dominates over the other one. Dominant alleles cannot completely cover up the recessive alleles. Descendents possess an intermediate phenotype between the two parental phenotypes and not the dominant one, which would appear if this would be the case of complete dominance.
Available data:
Two short-tailed Manx cats are bred together. F1: 3 kittens with long tails, 5 short tails, and 2 without tails.The T gene might express the tail trait. T allele expresses long the tail and is dominant over t allele which expresses the absence of the tail.
So, homozygous dominant individuals, TT, are long-tailed animals
homozygous recessive individuals, tt, have no tail
Heterozygous individuals, Tt, are short-tailed animals, the intermediate form.
Cross: Two short-tailed Manx cats are bred together
Parental) Tt x Tt
Gametes) T t T t
Punnet Square) T t
T TT Tt
t Tt tt
F1) 1/4 TT = Long-tailed animals
2/4=1/2 Tt = Short-tailed animals
1/4 tt = untailed animals
The ratio 3:5:2 of the progeny in the example is close enough to the Mendelian ratio 1:2:1.
Answer:
This is a case of incomplete dominance. Consider the genotypes below:
LL - long tailed
Ll - short tailed
ll - no tail
The parent genotype is Ll. This means they have the ability to produce offspring with either of the 3 given phenotypes depending on the combination of alleles that get passed down. The cross would be the following way:
L l
L LL Ll
l Ll ll
There's a 25% chance of long-tail, 50% chance of short-tail and 25% chance of no-tail.
