Do you think populations stay in genetic equilibrium after the environment has

Answer:

Do you think populations stay in genetic equilibrium after the environment has changed significantly? ... It is likely because after the population changes, it is sufficient for its environment and does not need to go through change.

Answer: ° Pop Beads represent two pair of homologous sister chromatids.

° In terms of number and kinds of chromosomes, Chromosomes number will be the same, Also Similarity of genetic information will be the same.

°Interphase

Prophase

Metaphase

Anaphase

Telephase

° In terms of number and kinds of chromosomes; resulting cells will resemble only half of the chromosome. Also, there will not be exact correspondence in similarity of genetic information as their parents.

° Haploid Cells (n) are cells that contains a single set of chromosomes e.g sex cells (egg or sperm cell)

Diploid cells (2n) are cells that contains two set of homologous chromosomes. A vivid example of these are the somatic cells.

° Chromosomes are replicated only once in meiosis.

° Chromosomes are pulled to opposite poles in meiosis only twice.

° Crossing Over also known as genetic recombination can be defined as the exchange of genetic materials between two homologous chromosomes non sister chromatids which pair up to form recombinant chromosomes.

Explanation:

Since we have questions with multiple attachments, repetition of words will be avoided and those that need explanation will be our focus.

1° When we hear Pop Beads, it's pertinent to think biologically that Pop Beads are used in tracking chromosomal DNA movements in Cell Division.

Thus, Pop Beads represent extensions of homologous Sister Chromatids

2° Let's recall : that both diploid and haploid cells can undergo mitosis. Mitosis is a division of a cell nucleus in which the genome is copied and separated into two identical halves. Hence, in terms of numbers and kinds of chromosomes; if (for example) a diploid cell undergoes mitosis, the resulting cells will be two identical diploid cells i.e (2n = 2n).

Therefore, chromosomal number and genetic information will be the same.

4° In meiosis, cell division occurs that reduces the chromosomes number by half, giving rise to four haploid cells, each genetically different from their original (parent) cells.

Hence, in terms of numbers and kind of chromosomes, the resulting cells will produce half of the chromosomes. Also, genetic information will differ from their original cells.

6° If we look at what Chromosomal replication is, we'll realize that: it's a biological process of producing two identical replicas of chromosomes from one original chromosomal molecule.

In meiosis, chromosomal replication occur "ONCE" . But there are two rounds of cell division. (Meiosis 1) where exchange of genetic information of takes place and (Mieosis 11) where daughter cells divides and splits up into sister chromatids to form haploid gametes.

7° Like we said earlier, Chromosomes are pulled to opposite poles in meiosis only "TWICE".

The first occurs at (ANAPHASE 1), when a pair of chromosomes are pulled apart by meiotic spindle, which in turns pulls one chromosome to one pole of the cell and the other chromosomes to the opposite pole.

In (meiosis 11), Chromosomes are pulled to opposite poles at (ANAPHASE 11); when daughter cells line up along the equator and centrioles are now at opposite pole creating avenue for meiotic spindle fibre to attach to each sister chromatids at ends of each poles.

Explain the limiting factors that control population growth
serg [7]

Competition - when space is full pack organisms compete for resources and the sooner the resources are gone. Predation - organisms feed on and kill animals lowering their population growth and the prey population growth, same as herbivore and human prey. Disease - again feeds on hosts. Stress from overcrowding - females could kill offspring. Hurricanes (density-independent limiting factors).
