Cell Division Homework #1 Introduction to Cell Division Directions: Compare and contrast the following pairs of terms:
wel

Answer:

Sister chromatids / centromeres: When a single chromosome has been replicated in copies, each copy is called a sister chromatids.

A special part of the chromosome called the centromere holds the two sister chromatids together. A centromere is like a built-in rubber band for two sister chromosomes.

Mother cell / daughter cell: identical.

Daughter cells are genetically identical to the mother cell at the stage of production through mitosis.

On the other hand, at the stage of production through meiosis, the daughter cells are genetically different and contain only half of the genetic material of the mother cell.

Interphase / cell division: A cell spends most of its time in what is called interphase, and during this time it grows,

replicates its chromosomes, and prepare for cell division.

The cell then leaves Interphase, undergoes mitosis, and completes its division.

DNA / chromosome: Genes are segments of deoxyirbonucleic acid (DNA) that contain the code for specific protein that functions in one or more types of cell in the body

Chromosomes are structures within cells that contains a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.

Mitosis / cytokinesis: Basically, mitosis is a process by which the duplicated genome in a cell is separated into halves that are identical in nature.

Cytokinesis is the process where the cytoplasm of the cell divides to form two 'daughter' cells. The result is the formation of two 'daughter cells', each having a nucleus.

Do fish have an open or closed circulatory system? What does this mean?​
dedylja [7]

Answer:

They have a closed circulatory system.

Explanation:

In an open circulatory system, blood vessels transport all fluids into a cavity. When the animal moves, the blood inside the cavity moves freely around the body in all directions.

Closed circulatory systems are different to open circulatory systems because blood never leaves the blood vessels. Instead, it is transferred from one blood vessel to another continuously without entering a cavity.

Which of the following is a postzygotic isolating barrier?
Jet001 [13]

Answer: The following is a <u>postzygotic isolating barrier </u>:

  • The hybrid offspring of two species of crocodiles can produce normal gametes but cannot obtain a mate.  

Explanation:

<em><u>Reproductive isolation </u></em>occurs when <em>barriers prevent</em> two populations from interbreeding , <u>keeping their gene pools separate.</u>

We can find the Prezygotic isolation that occurs<u> before fertilization </u>can happen.

And the Postzygotic insolation barriers are the reproductive insulation processes that<u> act after the mating</u>. They are all that concern the viability of the individuals produced.

Prezygotic isolation barriers can be temporal, behavioural, geographic , ecological or mechanical; whereas postzygotic isolation barriers include the inviability, infertility or breakdown of hybrid organisms
