Answer:
A) splitting water molecules I believe
When oxygen is released as a result of photosynthesis, it is a direct by-product of splitting water molecules.
PHOTOSYNTHESIS:
Photosynthesis is the process whereby green plants obtain their food (glucose) using energy from sunlight. Photosynthesis occurs in two stages namely: light dependent reaction and light independent reaction. In the light dependent reaction, chlorophyll molecules absorb light and the released electron is used to split water molecules into hydrogen and oxygen gas. Therefore, the release of oxygen gas is a direct byproduct of the splitting of water molecules called photolysis.Learn more at: https://brainly.com/question/25027435?referrer=searchResults

Answer:
All alleles on the X chromosome are dominant
Explanation:
This is because the X chromosome is large and contains many more genes than the smaller Y chromosome. In a sex-linked disease, it is usually males who are affected because they have a single copy of X chromosome that carries the mutation.

What is the importance of neutral variation in evolution?
A trait that is neutral in one environment may be advantageous in another.
It is usually removed from the population by natural selection due to its deleterious phenotypes in the environment.
A trait that is neutral will most likely be removed from the gene pool.
It will cause for a population to risk decline and extinction.
Answer:
A trait that is neutral in one environment may be advantageous in another.
Explanation:
Neutral variation refers to the variation (either genetic or phenotypic variation) which is unaffected by natural selection. Neutral variation is known to increase genetic variation, which is a prerequisite to evolutionary change. An allele may be neutral in one environment and beneficial (or deleterious) in another. In consequence, neutral variation in one environment may increase the response to selection in different environmental conditions.

Yellow-eyed salamanders have been cited as an example of Batesian mimicry; their orange body color and yellow eyes mimic the coloration of the toxic California newt. Although the salamanders are palatable, their mimicry of a unpalatable species tends to prevent predators from attacking. In a follow-up study, Kuchta et al. observed the reaction of Western scrub jays (predators with toxic newt experience) when presented with both a yellow-eyed salamander and a closely related species after being presented with a toxic newt. What was significant about this study
Answer:
It was a follow-up controlled experiment that showed how a species can influence selection in another species.
Explanation:
A follow-up (cohort) study is a type of study followed over time in order to determine the development of a particular outcome. Moreover, a controlled experiment is one in which conditions are controlled by the researcher, and thereby it is easier to determine the incidence of the outcome. In the case above described, researchers performed a follow-up controlled experiment in which they measured how a species can influence selective processes undergone by other species.

3. You are studying a population of pangolins (a scaly anteater), and you determine that there are two scale phenotypes: a thick scale that is dominant to a thin scale. You also find that thick-scaled individuals are better able to survive encounters with predators.
What evidence would you need in order to determine if this selective advantage is changing the population? (1 point)
-The number of individuals displaying each phenotype in the current generation.
-The number of individuals displaying each phenotype in the offspring.
-The number of individuals that survive predator encounters.
-The number of individuals displaying each phenotype in both the current generation and the offspring.
Answer:
The number of individuals displaying each phenotype in both the current generation and the offspring.
Explanation:
The number of individuals displaying each phenotype in both the current generation and the offspring. The correct option is 4.
What is phenotype?The phenotype is the set of observable characteristics or traits of an organism in genetics.
The term encompasses the organism's morphology, developmental processes, biochemical and physiological properties, behaviour, and behavioural products.
To see if the thick scale phenotype's selective advantage is changing the population, we must compare the frequency of the thick scale phenotype in the current generation to its frequency in the next generation.
This would necessitate data on the number of people who exhibit each phenotype in both the current generation and their offspring.
As a result, the evidence we require to determine whether the selective advantage is changing the population is "the number of individuals displaying each phenotype in both the current generation and offspring."
Thus, the correct option is 4.

Why do you think analogous structures would cause Evolutionary biologists problems when trying to determine the relatedness of certain species?
Answer: Two analogous structures are similar in phenotype and developed to perform the same function, despite not being inherited from a common ancestor. As so unrelated species may look related due to having analogous structures.
Explanation:
Analogous structures evolved due to Convergent evolution. It means that structures are similar in functions but differ in morphology.
What do you mean by Species?A biological species is a group of organisms that can reproduce with one another in nature and produce fertile offspring.
Analogous structures are similar in structure that evolved independently in two living organisms to serve the same purpose. Due to their approx similarity sometimes evolutionary biologists face problems when trying to determine the genetic relatedness of certain species.
Therefore, Analogous structures evolved due to Convergent evolution. It means that structures are similar in functions but differ in morphology.
