Transitional fossil evidence shows intermediate steps in the evolution process. So, the correct option is A.
What do you mean by Fossil?Fossils may be defined as the preserved remains, or traces of remains, of ancient organisms. They are dead and organic remains of past organisms.
Transitional fossil evidence would show intermediate forms of a species and they changed and accumulated adaptations at a slow pace. These are remnants of an organism that came in the version of the current species.
Therefore, Transitional fossil evidence shows intermediate steps in the evolution process.

5. The reactants and products for respiration are exactly the
same for a plant cell and an animal cell, the difference is
the _______
of the reactants.
Answers
Answer:
Source
Explanation:
Respiration, which occurs in all living organism, is the metabolic process by which organisms obtain energy (ATP) via the breakdown of their food substances.
The process of respiration in plant and animal cells is similar in the sense that reactants and products for respiration are exactly the same for both cells. The reaction is as follows:
C6H12O6 (glucose) + 6O2 = 6CO2 + 6H2O
The difference between this process in plant and animal cells is the SOURCE of the glucose or food molecule that is broken down. Plants get their food from PHOTOSYNTHESIS (autotroph) while animals get theirs by feeding on other organisms (heterotroph).

A large population of Yellow perch lives in the East river. The Walleye is a larger fish that eats the Yellow Perch. Despite lots of prey all the Walleye have moved from the East river to a new river. What most likely caused the Walleye to move to a different river?
(A)There is a lack of food in the East river which caused the Walleye to move to a different area.
(B) The Walleye are no longer able to catch the Yellow Perch and need to move to a different area.
(C)There is climate change which has caused the resources to decline in the East river.
(D) There is pollution in the East river that the Yellow Perch are adapted to but the Walleye are not.
Answers
Answer:
(D) There is pollution in the East river that the Yellow Perch are adapted to but the Walleye are not.
Explanation:
To ensure survival and cntinurd sustenance in an environment, there is need for an animal to posses certain features which would enable her cope with the conditions of the environment. The ability of animals to successfully live and survive in an environment is made possible through adaptation as the animal's adaptive features ensures the animal is able to live through and cope. If the adaptive features aren't suitable for such environment, then migration has to occurs, leading the animal to find a more suitable environment for survival. In the scenario above, the East river was presumed to be a good habitat for the Walleye and Yellow Perch, in spite of the available and abundance of food, the Walleye migrated, which is most likely due the fact that the Walleye lack the adaptive features to survive in the East river probably due to pollution which the Yellow Perch is well adapted to.

The purpose of Phase II in rehabilitation is to control inflammation.
O a. True
O b. False
Answers
The correct answer is False.
Explanation
Rehabilitation has three main phases, the first of which is the first response to an injury, so the main objective in this phase is to defend the body against harmful substances, eliminate dead or dying tissue and promote the renewal of normal tissue. as well as alleviating pain, controlling the inflammatory response to injury and protecting the affected anatomical area. So you have to clean the wound, disinfect it, cover it, and in cases where it is required to put ice to reduce inflammation.
In the second phase the recovery of functional losses, so it is necessary to start making small movements in the affected area to reactivate its functions progressively.
The third phase is advanced rehabilitation in which functional training work begins with the aim of strengthening and putting the affected area back in a movement directed towards sports practice.
Therefore, the correct answer is False, because the inflammation control is done in Phase I and not in Phase II.

They obtain a tall pea plant of unknown ancestry, allow it to self-pollinate, and collect 80 of its seeds. After planting the seeds, they observe the growth of 61 tall plants and 19 dwarf plants. Which of the following best explains the stem lengths seen in the offspring?
A. Stem length is inherited through incomplete dominance.
B. Dwarf stem length is a recessive trait.
C. Stem length is a sex-linked trait.
D. The tall plants likely received more nutrition than the dwarf plants.
Answers
Answer:
The answer is B
Explanation:
just cause lol
The study of a living being is called biology.
The correct answer is B.
The characters in the plant are controlled by the genes which are present on the chromosome. The genes are always present in pairs and a single gene is known as an allele. The alleles are as follows:-
DominantRecessive.According to the question, most of the offspring are tall in height due to the dominant allele while the number of the dwarf plant is less as this character is shown by the recessive genes.
The dominant plant suppresses the character of a recessive gene and hence the number of the dominant plant is always more.
Hence, the correct answer is B. Dwarf stem length is a recessive trait.

A homeowner lives adjacent to some wetlands, which contain standing water for much of the year. During the summer months, the
mosquitoes in the area are excessive and pose a nuisance to the homeowner. The homeowner decides to spray an insecticide on
the lawn and adjacent wetlands to eradicate the mosquitoes. The homeowner notices that after the application of the insecticide,
the number of mosquitoes is significantly reduced.
The following year, the number of mosquitoes increases in frequency as the summer months arrive and the temperatures get
warmer. The homeowner once again applies the same insecticide to the yard and adjacent wetland areas. However, this time, the
homeowner does not notice a reduction in the mosquito population after applying the chemical.
Evaluate the scenario above and select ALL statement below that apply to this case study.

There were some mosquitoes with innate genetic resistance to the insecticide before it was sprayed the first time. Natural selection selects for a phenotype in a population that has an advantage under certain environmental pressure. The correct options are B, C, and D.
What is case study?A case study is defined as 'an intensive study of a person, a group of people, or a unit with the goal of generalizing across several units'.
A case study has also been defined as a focused, systematic investigation of a single person, group, or community.
The insecticide application resulted in directional selection in the mosquito population. Before the insecticide was sprayed for the first time, some mosquitos developed innate genetic resistance to it.
Natural selection favors phenotypes in a population that have an advantage under certain environmental conditions.
