After anaphase Telophase occur.

Explanation:

The M-phase of cell division involves two steps:

  • Karyokinesis: Division of nucleus.
  • Cytokinesis: Division of cytoplasm.

Karyokinesis has the folloeing steps:

  • Prophase: The nuclear membrane disappears and the cromatin fiber begins to condense and form chromosome.
  • Metaphase: The metaphase chromosome are well distinct and are arranged on the equilateral plane. And the kinetochore ttaches to the spindle.
  • Anaphase: The spindles begin to contract and the sister chromatids begin to separate and move towards respective poles.
  • Telophase: Chromatids are already at the poles and they become inconspicuos. The nuclear membrane begins to appear.

Telophase marks the end of Karyokinesis and soon the cytokinesis begins.

In plants cytokinesis occurs by cell plate formation.

In animal cell cytokinesis occurs by invagination.

Raccoons and lesser pandas have many corresponding sequences of nucleotides.
Oksanka [162]

Analyzing the proteins of the Racoons and lesser pandas, there will be huge similarities with minor modifications.

These species will be very closely related.

<h3><u>Explanation:</u></h3>

The evolutionary background of the species are mainly studied based on the similarities of the nucleotide sequences and proteins. While studying the Lesser pandas and Racoons, there was a huge similarities in then based on their structures, and on their protein composition. The nucleotide sequences also showed huge similarities which also points that they have developed from same ancestor. This is why they are very closely related with each other by means of evolution.

Balance and posture are the responsibility of the cerebellum, which coordinates body movements, uniting and articulating muscle movements so that they keep the body balanced and maintain its posture.

With this information, we can conclude that the part of the cns sent a signal to help prevent Jamal's fall was the cerebellum

How do the chromosomes in most cells of an organism, such as the leaf cells of a plant, compare to the chromosomes in its reprod
Lunna [17]

Answer:

Reproductive cells have half the amount of chromosomes than body cells

Explanation:

I think that you are talking about body cells when you say "most cells in an organism." If that is the case, then the reproductive cells, sperm and egg cells, have half the amount of chromosome than body cells.

For example: Human body cells have 46 chromosomes. Human reproductive cells has 23 chromosomes.

In sexual reproduction, each parent gives 1/2 of a full set of chromosomes to create the full set needed for an organism.

timurjin [86]
A cellular organelle is a structure in the cell that performs a specific function.

Nucleus - stores cell's DNA; DNA replication occurs here

Ribosome - produce protein; "factories" of the cell

Mitochondria - breaks down food for energy to be used by the cell; "powerhouse" of the cell

Vacuole - store materials such as food, water, sugar, minerals, and waste products

Endoplasmic reticulum - carry materials throughout the cell; "transport system"
