ANSWER QUICKLY!!! What phase of mitosis is shown in the picture above?

A. Metaphase
B. Anaphase
C. Telephase
D. Prophase

Answers

Answer:

B. Anaphase

Explanation:

The stage of meiotic or mitotic cell division in which the chromosomes move away from one another to opposite poles of the spindle.

The phase of mitosis which is shown below in the picture is Anaphase. During this phase, chromosomes break at centromeres.

What do you mean by Mitosis?

Mitosis may be defined as a process where a single cell divides into two identical daughter cells.

Anaphase is the phase of mitotic cell division where chromosomes break into chromatids that are separate from each other and are pulled towards the opposite pole with the help of spindle fiber.

Therefore, the phase of mitosis which is shown below in the picture is Anaphase.

Each cell of the muscles of a certain bug contains 28 chromosomes.
a. How many chromosomes are in its sperm cells?

Answers

Answer:

14 chromosomes

Explanation:

In the gametes of an organism, there are always half of how many chromosomes there are in the somatic cells of the organism. For example, if there are 4 chromosomes in the somatic cells, that means that there are 2 chromosomes in the gametes.

Somatic cells are body cells. They include everything from skin cells to brain cells to stomach cells.

Gametes are reproductive cells. They're the sperm and egg cells.

So if the muscle cells have 28 chromosomes, that means all somatic (or body) cells of that organism have 28 chromosomes.

So the gametes would have half of that amount:

28/2 = 14

So the sperm cells of this organism would have 14 chromosomes.

When does mRNA editing take place?

Answers

Answer:

After transcription, some RNA molecules are altered to contain bases not encoded in the genome. Most often this involves the editing or modification of one base to another, but in some organisms can involve the insertion or deletion of a base. Such editing events alter the coding properties of mRNA.

Consider a habitat with prairie dogs, bison, and red-tailed hawks. Another
species of hawk that eats prairie dogs, the ferruginous hawk, migrates into
the area. What effect will this change most likely have on the prairie dog and
red-tailed hawk populations?
O A. The prairie dog population will decrease, the red-tailed hawk
population will stay the same, and the bison population will
increase.
B. The prairie dog population will decrease, the red-tailed hawk
population will decrease, and the bison population will increase.

O D. The prairie dog population will decrease, the red-tailed hawk
population will decrease, and the bison population will stay the
same.

Answers

Answer:

B. The prairie dog population will decrease, the red-tailed hawk population will decrease, and the bison population will increase.

Explanation:

I'm not given context; however, I am assuming that the prairie dog preys on the bison because the bison is commonly known as a herbivore.

If another predator who preys on the prairie dog is introduced, there is increased competition with the red-tailed hawks. Although this doesn't directly impact the population of red-tailed hawks, it reduces its food supply (of the prairie dog) because it is being shared, so it will have less food to grow at the optimal level.

With the increased consumption of the prairie dog, naturally, that would leave its prey; the bison, to have a lower level of predation, thereby the population increasing.

Using the illustration above, why are the chromosomes in two of the sex cells different from the chromosomes in the parent cell?


A

the chromosomes from another parent cell were introduced


B

crossing over occurred in the chromosome


C

an insertion mutation occurred during replication


D

some of the genes were damaged during replication

Answers

Answer: A  the chromosomes from another parent cell were introduced

Explanation: A child is created when the male sex cell joins the female cell. If the male and female sex cells had the standard number of chromosomes, as is found in body cells then the zygote (baby) would have double that number of chromosomes. The number of chromosomes would keep doubling every generation. To avoid this doubling the parent's body cells split by miosis which halves the number of chromosomes and so when the sex cells join the total number of chromosomes is the same as that found in the parent's body cells.

Which characteristic is most useful in correlating Devonian-age sedimentary bedrock in New York State with Devonian-age sedimentary bedrock in other parts of the world?

Answers

Complete question:

Which characteristic is most useful in correlating Devonian-age sedimentary bedrock in New York State with Devonian-age sedimentary bedrock in other parts of the world?

a. Color

b. Index fossils

c. Rock types

d. Particle size

Answer:

b. Index fossils  

Explanation:

Fossils are animal and vegetable rests found in different strata of sedimentary rocks. Sedimentary layers deposit chronologically, so they are used to reflect history. They keep in each layer some of the forms of life that inhabited that area in the past. These fossils turn to be very useful while dating ages. The term Index fossils refer to those fossils that only existed in a given era or geological period during evolution.

Index fossils must:

Be easily recognizable and distinguishable from all the other fossilsHave lived in a relatively short geological periodPresent a wide geographic distributionHave lived in different sedimentary basinsAppear in different types of rocksBe abundant

In the exposed example, we are looking for a correlation between the Devonian-age sedimentary rock layers from New York with the Devonian layers of other parts of the world. This comparison is the same period (Devonian) and in places that might be far away from each other, meaning there was a wide geographical distribution of the species.

A quick evolution and extinction contribute to narrow the geological period of their existence, increasing the chronological precision. Widely distributed fossils allow geologists to establish relationships between rocks that are far away from each other.

Water enters in the root through a process is called osmosis until it reached to the xylem vessel. Osmosis is a movement of molecules through a semi-permeable membrane into a region of higher solute concentration in order to equalize the solute concentration.

In a food chain 200 kg of wheat is fed on by 18 kg of mice which in turn are eaten by 1kg of hawk. What is the percentage energy transferred from the first trophic level to the third?

Answers

Answer:

0.1% of energy

Explanation:

Energy flow: From the whole quantity of energy that reaches the earth's surface, autotroph organisms or producers absorb only 0.1 or 1%.

From the input of solar energy begins a unidirectional energy flow through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is dissipated in the environment.  

At each trophic level occurs an energy transfer to the next, with only 10% being usable in each of them. This assessment is called "The 10% rule". As a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time.

If wheat transferred 10% of the energy to mice, and of that 10% mice transferred 10% of the energy to hawk, then the percentage of energy transferred from the first trophic level to the third equals 0.1%.

10% (1st TL-2nd TL) / 10% (2nd TL - 3rd TL) = 0.1% (1stTL - 3rd TL)

TL = Trophic level
