Answer:
A
Explanation: You can see that the green colored frogs were once lower than the blue and as time started progressing the green started getting a higher population over the blue, as the blue decreased.
For the frogs, the green skin color is being selected over blue skin color. This leads to the abundance of the skin color in the third generation.
What is natural selection?
Natural selection refers to a situation in which traits that enable organisms to better survive and adapt in their habitat tend to persist whiole other traits gradually disappear.
In this case, we can say that the green skin color is being selected over blue skin color.

Which material heats fastest, the rock, the sand or the water?
Explain your answer.
Answer:
Sand
Explanation:
Sand heated up faster than water because sand is darker than water; dark-colored materials will absorb more light. Sand heated up faster than water because sand is a solid and water is a liquid. Water is a slow conductor of heat, thus it needs to gain more energy than the sand or dry land in order for its temperature to increase. On the other hand, soil loses its heat much faster. Water has to lose more energy than the sand (dry land) in order for the temperature to decrease.

A group of researchers are studying stem length inheritance in the garden pea plant (Pisum sativum). 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.
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.

On your Spring Break in Mexico, you take a break to count the starfish in a tidal pool. You notice that there is a rare recessive trait that causes the starfish to have 6 legs instead of 5. Of the 27 starfish you can find, only 1 has 6 legs. What are the allele frequencies for this population
Answer:
0.04 for 6 legs starfish and 0.96 for 5 legs starfish.
Explanation:
The allele frequency for the 6 legs starfish is 0.04 whereas, the allele frequency for the 5 legs starfish is 0.96 because there is only one 6 legs starfish in the given population as compared to 5 legs starfish. The low population of 6 legs starfish is due to the presence of recessive allele while on the other hand, higher population of 5 legs starfish is due to the presence of dominant allele. The allele frequencies for both population is done by dividing the allele of interest by total number of alleles present in the population.
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.
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).

What would cause a person to have two copies of the bent thumb allele (tt)?
1. A person whose mother or father had two copies of the bent thumb allele will always have two copies of the allele.
2.A person with two copies of "t" inherited one from their mother and one from their father.
3. A person born with one "t" mutation is more likely to develop a second "t" mutation during their lifetime.
4. A person with two copies must have duplicated the "t" allele through mitosis early in development. (They inherited one, then doubled it)
Answer:
A person with two copies of "t" inherited one from their mother and one from their father
Explanation:
This is because both the father and the mother are carriers of "t" alleles which is a bent thumb. When the parent mate, the father donate one t and the mother too donate one t allele, therefore the person will inherit bent thumb from them.

Sometimes an organ can be replaced by moving it from one part of the body to another. This can be done, for example, to replace damaged skin or joints. In these cases: rejection of the transplanted organ would not be expected. antibodies would be generated against the transplanted organ. antigens would be generated against the transplanted organ. immunosuppressant drugs would be required to prevent transplant rejection. rejection of the transplanted organ would still be expected.
Answer:
rejection of the transplanted organ would not be expected.
Explanation:
Organs can be defined as specialized body tissues united to perform specific functions in living organisms. Some examples of organs found in humans are brain, bladder, kidney, heart, intestine, eyes, lungs, liver, etc.
In the field of Medicine and Surgery, an organ is sometimes replaced for specific reasons, by moving it from one part of the body to another; this process is generally referred to as a transplant. Thus, it's mainly done to replace damaged skin or joints in the body of a living organism such as humans.
Hence, in these cases, rejection of the transplanted organ would not be expected because an examination and matching of the organ is carried out by the medical professionals before transplant.
Some cells release active signaling proteins when membrane-bound precursor proteins are cleaved by proteolytic enzymes. The signaling proteins can then bind to receptors on the surface of a target cell, thereby activating an intracellular signaling pathway and eliciting a response from the target cell. This mechanism of activating receptor-binding signaling proteins has been observed in a variety of organisms from bacteria to humans. Many of the enzymes responsible for proteolysis of membrane-bound precursor proteins have been isolated and characterized.
Required:
What questions would be most appropriate to investigate whether the proteolytic enzymes are evolutionarily conserved among species?
Answer:
Following questions would be most appropriate to investigate whether the proteolytic enzymes are evolutionarily conserved among species:
Are the genes encoding the proteolytic enzymes expressed in the same cell types in all species? Once the precursor proteins of different species are cleaved, do the active signaling proteins bind to the same receptors on different target cells? If a proteolytic enzyme from one species is incubated with a precursor protein from another species, does correct cleavage occur? Are the proteolytic enzymes synthesized in the rough endoplasmic reticulum of all species?
