You're stalking about soilds, liquids and gases?

A fixed matter means created yeah?

So maybe a liquid that can freeze into a solid.

Answer:

In the above experiment, these three flies are not enough cogent

Explanation:

Because in the above experiment which is designed to test that, in the above cage these three flies prefer which type of food either it is a banana which is fresh or either apple which is rotten. But the behavior of the flies is not the same, so it is difficult to judge where the flies spend more time. It is a probability that the flies spend most of the on a fresh banana or a rotten apple or both fruits.

These three flies could be unusual.

<span>a. replicate DNA at the appropriate time.

Prokaryotes are one celled organism that only reproduce by binary fission. A copy of a copy, of course the DNA is copied as well. DNA is duplicated a succinct period of time when necessary since the energy needed to perform this process is necessarily abundant. </span>

Place the events in the correct order:
Alecsey [184]

Answer:

1. Chromatin condense into chromosomes.

4. Homologous chromosomes pair up (formation of tetrads).

5. Homologous chromosomes separate and move to poles.

2. Sister chromatids separate.

3. Chromosomes unravel in to chromatin.

Explanation:

This question portrays the process of meiosis in a cell. The ordered sequence of events in the options are:

1. Chromatin condense into chromosomes - This process occurs in the Prophase stage. Prior to the cell division, the nuclear material is found as Chromatin material. This Chromatin material then undergoes condensation to form visible chromosomes.

4. Homologous chromosomes pair up (formation of tetrads) - This process also occurs during the Prophase stage of meiosis I. In this stage, homologous chromosomes (similar but non-identical chromosomes received from each parent) are paired up side by side to form a structure known as TETRAD or BIVALENT.

5. Homologous chromosomes separate and move to poles - This process characterizes the Anaphase stage of meiosis I. Homologous chromosomes are pulled apart to opposite poles of the cell by spindle microtubules.

2. Sister chromatids separate - After meiosis I, meiosis II involving sister chromatids instead of homologous chromosomes follows. In the Anaphase stage of meiosis II specifically, sister chromatids are pulled apart towards opposite poles of the cell.

3. Chromosomes unravel in to chromatin - After the whole division process i.e. karyokinesis (division of the nuclear material), the chromosomes begin to unravel to form the CHROMATIN threads once again. This process occurs in the Telophase stage of meiosis.
