W Within a forest ecosystem, there is a large amount of diversity among members of a warbler species. Of the following stages of meiosis illustrated for a typical cell, which contributes most to diversity among the warblers? Pay special attention to the chromatids.​

Answers

Answer:

Explanation:

How a Forest Ecosystem Matures . Forest ecosystems tend to always be moving toward maturity or into what foresters call a climax forest. This maturing, also called forest succession, of the ecosystem increases diversity up to the point of old age where the system slowly collapses. One forestry example of this is the growth of trees and the entire system moving toward an old growth forest.

A Large amount of warbler species, crossing over between homologous chromosomes, is closely involved in genetic variation. The stage that most contributes to diversity is stage C, where you can see chromosomes after crossing-over.

There are different mechanisms involved in producing genetic variation among descendants, are-

Crossing-over between homologous chromosomes (prophase 1), The Random lining of homologous chromosomes (metaphase 1),

Random fertilization

The Crossing-over events occur between two homologous chromosomes within the equatorial plane and make the daughter cells genetically different from the first one.

The Chiasma is the position where two homologous chromatids interchange genetic information, giving an area for brand spanking new genetic material or information to be provided to descendants.

After crossover, homologous chromosomes get separated again. In the attached image there are four different stages of meiosis.

Stage C is the one that contributes foremost to diversity. We can see that crossover has already occurred between homologous chromosomes and that they have already interchanged segments.

In the image, you will see the difference between chromosomes that have gone through the crossing over mechanism, and chromosomes that have not. The difference in color represents segments interchange and variation.

Therefore, that answer shows the contribution to diversity among the warblers.

Binding of ________________ to receptors (ligand-gated) on the sarcolemma at the neuromuscular junction is vital for depolarization of the muscle fiber.

Answers

Answer:

Binding of   ACh (acetylcholine)    to receptors (ligand-gated) on the sarcolemma at the neuromuscular junction is vital for depolarization of the muscle fiber.

Explanation:

It allows acetylcholine to be released into this synapse when an action potential hits a neuromuscular junction. Acetylcholine attaches to the nicotinic receptors localized on the post-synaptic membrane of the muscle fibre's motor end plate, a specialized region.

Hence , the answer is  ACh (acetylcholine) .

How many chromosomes will be found in
each of the two new cells formed as a result
of mitotic cell division?

Answers

At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes.

23 pairs of chromosomes will be found in each of the two new cells formed as a result of mitotic cell division.

WHAT IS MITOSIS:

Mitosis is a kind of cell division that results in the formation of two daughter cells with the same number of chromosomes as the parent cell.

Mitosis is used for growth and tissue repair in living organisms. In mitosis, a parent cell divides into two new daughter cells, however, each cell possess the same number of chromosomes as the parent.

In a somatic human cell, there are 23 pairs of chromosomes (46 chromosomes). If this cell undergoes mitotic division, then, there will be 23 pairs of chromosomes in each cell formed.

Removing a specific group of trees within a small area over a long period of time is
a. clearcutting
b. seed tree cutting
C. group selection
d. single tree selection

Answers

Answer:

C. group

Explanation:

Removing a specific group of trees within a small area over a long period of time is group selection. The correct option is C.

What is group selection?

A quantitative definition of group selection is when the average group fitness is greater or less than the mean of the fitness values of the individual members.

Another definition of group selection is when features evolve in accordance with the fitness (survival and reproductive success) of groups.

The conclusion was that although group selection is theoretically feasible, in practice it almost always favors one group over another.

Group selection is the long-term removal of a certain group of trees in a constrained region. In a clearcut, all the trees in a specific region are taken out at once.

The removal of shelterwood cutting clears an area's also clears land cleared for shelterwood cutting, which also involves cutting downing shelterwood cutting, but it is a completes a method of clearing

Thus, the correct option is C.

Answers

Answer:

The Golgi apparatus plays a central role in molecular transport after biosynthesis.

Explanation:

Transcription occurs in the nucleus during protein synthesis, followed by translation inside ribosomes. Then, new molecules join the endoplasmic reticulum to be folded and modified. In the Golgi, they are tagged and separated into lysosomes for export outside the cell.

 The Golgi system comprises of several regions known as cisternae; they act as independent microenvironments where products requiring their own unique conditions are converted into new, stable biomolecules.

Answers

Is this without equipment?

Depending on what organism you are talking about, animals that can be seen with the unaided eye you can tell that they are dead by studying their bodily movements such as the rise or falling of their chest.

Plants with the unaided eye, the best  indicator is to take a branch or piece off and study the insides color, if it is green then mostly likely they are alive.

Now microscopic organisms are harder to say, it depends on what you are referring to.

On a scratch sheet of paper, complete the Punnett square of the cross between two heterozygous red-eyed flies (Rr). What color eyes will the offspring have?

Answers

Answer:

75% red, 25% other color (brown?)

Explanation:

A cross between two heterozygous red eye flies (Rr x Rr)

                     R                     r

R                  RR                   Rr

r                   Rr                   rr

The possible genotypes are RR, Rr, and rr. There are two possibilities of Rr.

Since the heterozygotes have red eyes, the red eye allele must be dominant. Therefore, RR and Rr genotypes will all have red eyes. That means 3/4 (75%) of offspring will have red eyes. 1/4 25% are h0m0zygous recessive (rr), and will therefore have the other eye color (question doesn't mention which colour this is, it is likely brown)
