Answer:

2:2 ratio of inherited genes

Explanation:

There are two RR offspring that will be blue.

There are two offspring with Rr that will also be blue.

R is a dominate trait. With the presence of it in the genes, it will always be expressed over the recessive r trait.

Answer:

The daughter cells have the same number of chromosomes and the same amount of DNA.

Explanation:

Mitosis is a process where the nucleus divides, so at first we have 46, and we need to bring it down to 23, because that is how much our cells can take, but after mitosis, the daughter cell will end up with 2 new cells, and it will have 23 chromosomes in each of the cells.

To know if two genes are linked or assort independently, a testcross can be performed. If the progeny distribution differes from the expected ratio, they are linked. Extected numbers: -100 curved wings, ebony body -100 curved wings, gray body -100 straight wings, gray body -100 straight wings, ebony body.

Independent assortment law establishes that the alleles from two or more different genes distribute independently from each other in gametes.

Each gamete receives an allele from a gene that does not depend on nor influence another gene's allele in the same gamete. This event only occurs in independent genes. These genes segregate independently after crossing over because they are far away from each other.

Some other genes, however, are too close to each other, and they do not segregate independently. These are the linked genes. They do not exhibit an independent distribution, and they are inherited together more frequently.  

To know if two genes are linked, we must observe the progeny distribution.

In the exposed example,

1st Cross: flies with curved wings and gray bodies to flies with straight wings and ebony bodies.

Parentals) ss GG   x   SS gg

F1) 100% Ss Gg

2nd cross: F1 individuals testcrossed

Parentals) Ss Gg   x   ss gg

F2)  

Total number of individuals: 400

Hypothesis: Both genes assort independently from each other.

We need to give the expected values. As said before, the expected ratio is 1:1:1:1 ⇒ 4/16 Ss Gg : 4/16 Ss gg : 4/16 ss Gg : 4/16 ss gg

16 possible genotypes --------------- 400 individuals

4 Ss Gg ----------------------------------- X = 100 individuals

4 Ss gg ----------------------------------- X = 100 individuals

4 ss Gg ----------------------------------- X = 100 individuals

4 ss gg ----------------------------------- X = 100 individuals

Answer:

Plants, like all living things, need food to survive. Plants make their food using a process called photosynthesis, which means “putting together through light.” During photosynthesis, a plant traps energy from sunlight with its leaves. It also takes up water from its roots and carbon dioxide gas from the air.

Answer:

The correct answer is A, C, and D only.

Explanation:

A neurotransmitter is a biomolecule, generally synthesized by neurons, which is poured from vesicles in the presynaptic neuron into the synaptic gap and produces a change in the action potential of the postsynaptic neuron. Depending on the nature of the neurotransmitter, this can be synthesized in the neuronal soma or in the nerve endings. Some neurotransmitters are synthesized directly in nerve endings thanks to enzymes that have been synthesized in the soma and transported to these endings. Through the interior of the axon flows a current of substances free or enclosed in vesicles, which can be precursors of both neurotransmitters or their enzymes, called axonal flow.Another characteristic of the transmitter function in each of the substances commonly accepted as neurotransmitters is that when administered exogenously as a drug that in reasonable concentrations perfectly mimics the effects of the endogenously released transmitter.

Neurotransmitters should be defined by four essential characteristics. It involved the A, C, and D only.

Neurotransmitters refer to the chemical messengers in the body that should transform the message from the nerve cell. Also, it should be synthesized in neurons and stored in the presynaptic terminal. It should be the vital attribute at the time when the chemical should mimic the activity of endogenous due to which it gets a similar response. Also it eliminates the activation site.

The carbon reservoir that has the longest residence time is known as a fossil deposit. Thus, the correct option for this question is D.

A carbon reservoir may be defined as being stored form of carbon in rocks and sediments. The rest is located in the ocean, atmosphere, and in living organisms. These are the reservoirs through which carbon cycles.

The movements of carbon take place through the four major reservoirs of the earth. It includes the biosphere, lithosphere, hydrosphere, and atmosphere. Plant biomass holds carbon for a very less period of time followed by soil. But the deposits of fossils hold the concentration of carbon for a maximum period of time.

Therefore, the carbon reservoir that has the longest residence time is known as a fossil deposit. Thus, the correct option for this question is D.

Answer: B

Explanation:

To help the pioneer species to grow, it needs to have rapid reproduction. But, it also needs the sun to grow very well. If it does not have the Sun, it will most certainly die and be endangered in the area. The answer is B, we need both rapid reproduction and the Sun.

Answer:

rapid reproduction and the ability to grow in sunny places

Explanation:

After a major fire, less sunlight is blocked by trees and other plants. Plants that can use the increased sunlight are more likely to thrive in the new environment. Rapid reproduction would help a plant species to spread more quickly to take advantage of the resources and lack of competition. Therefore, the adaptations that would help grass be a successful pioneer species are rapid reproduction and the ability to grow in sunny places.
