Answer:

The moment where the nuclear envelope forms at each pole spindle dissolves chromosomes uncoil is called Telophase.

Explanation:

In the eukaryotic cell, telophase is the final stage in meiosis and mitosis. In this step, the effects of prophase and prometaphase are reversed. This is the forth stage and a nuclear envelope forms at each pole. The spindle dissolves and the chromosomes uncoil, cytokinesis begins. The cell continues to enlogate.

Answer: telophase

Explanation:cell division is important for the growth and continous existence of organisms.it may be mitosis or meiosis. These processes usually occurs as Prophase,metaphase, anaphase and telophase.meiosis has these stages in two set of division.

In Prophase,the chromatin condenses. the nuclear membrane and nucleolus disappears.

In metaphase,the chromosomes migrate and attach to the spindle fibres.

In anaphase, spindle fibres shorten thereby pulling the chromosomes apart , towards opposite poles of the spindles.

In telophase,the separated chromosomes arrive at the poles of the cell. All the activities which took place at the Prophase is reversed.the spindle breaks down,the chromosomes lengthen and becomes threadlike.the nucleolus reappears.the nuclear membrane forms.

Cytokinesis then occurs and two daughter cells are formed.

Scientist are studying an 500g. Sample of a radioactive element. Which has an annual decay rate of 11%. How many grams of the sa

gtnhenbr [62]

Nothing

Explanation:

Mass of the sample = 500g

Decay rate per anum = 11%

Unknown:

Mass of sample remaining after 10yrs = ?

Solution:

This is a simple percentages problem;

The radioactive sample loses $\frac{11}{100 }$ x 500g of sample per year;

this is a loss of 55g per year;

In 10years time, the sample would have lost 10 x 55g = 550g of element.

Since our sample is not up to 550g, then no amount of sample will remain after 10yrs.

seeds that are planted upside down are still able to grow into mature plants which explanation best explains this phenomenon?

pav-90 [236]

Answer:

This question is incomplete but the completed question is below

eeds that are planted upside down are still able to grow into mature plants. Which explanation best explains this phenomenon?

(a)The roots change into branches, and the branches turn into roots.

(b)The roots grow toward the force of gravity, and the shoots grow away.

(c)The plant will become a smaller version of a mature plant.

(d)Roots always grow toward the dark, and shoots grow toward the light.

Two options appear to be correct here: options B and D

Explanation:

Regardless of the direction the seed is planted, the seed has the ability to re-position itself via the help of growth hormones that respond to gravity and redirect the seed into the proper orientation. However, after re-orientation of the seed, the root grows toward the direction of gravity (a process known as gravitropism) while the shoot grows toward the direction of sunlight (a process known as phototropism). Even though two options appear to be correct here, the most correct option based on he question is b

Cattle and buffalo share a similar fundamental niche, the entire set of conditions under which a population can survive and repr

Vadim26 [7]

Answer:

The data in the Venn diagram suggest about the realized niches of the cattle and buffalo and their ability to coexist with evidence is discussed below in detail.

Explanation:

From the graph, it is observed that Cattle and Impala have the most overlay in their nutrition.

When Sorensen's index worth is more like 1, there is a contestant among animals for their food manner needs.

From the Venn diagram, we recognize that Cattle and Impala have the most overlay in their nutrition. Also, Sorensen's index worth = 0.82 (closer to 1 concerning other partners.

Sorensen's index for Buffalo and Cattle is 0.48 (cheapest among these 3 partners). So, they are less competitive. So, they can persist and generate easily.
