In order for two new cells to be created during mitosis, each cell must receive an identical copy of DNA. In order to accomplish this task efficiently prior to mitosis, a cell will condense DNA into

Answers

Answer 1

Answer:

chromosomes

Explanation:

A cell must condense DNA into chromosomes before it can divide mitotically to form two new cells with identical copies of DNA.

The condensation of the DNA happens at the initial phase of the mitosis - the prophase - during which the DNA thickens and condenses to form chromosomes.

These chromosomes then align at the cell's plate during metaphase and they become separated into sister chromatids through the pulling of the spindle fiber at anaphase. Separated chromatids of the same chromosome are then transported to the opposite ends of the cell where they decondense before cytokinesis takes place.

A mutation that could be inherited by offspring would result from-?

Answers

Answer: Along with substitutions, mutations can also be caused by insertions, deletions, or duplications of DNA sequences. Some mutations are hereditary because they are passed down to an offspring from a parent carrying a mutation through the germ line, meaning through an egg or sperm cell carrying the mutation.

Explanation:

A mutation that could be inherited by offspring would leads from a base substitution in gametes during meiosis. The correct option is D.

What is mutation?

Any alteration to a cell's DNA sequence. Alterations in cell division can result in specific mutations.

As can exposure to environmental DNA-damaging substances. Mutations may be negative, positive, or ineffective.

Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.

Somatic mutations (which happen in body cells) cannot be passed on to offspring, whereas germline mutations (which happen in eggs and sperm) can.

A base substitution in gametes during meiosis would result in a mutation that might be passed on to progeny.

Thus, the correct option is D.

People have bred dogs in certain ways that makes it hard for them to breathe, like Bull dogs who has respiratory issues. This makes decreases their life span and continuing to bred them will only make it worse. When scientist have a certain trait they want they also make animals breed with their own families.

write four observable differences between rat and toad​

Answers

Answer:Frog or toad: how to tell the difference

Skin

If there was ever a tell-tale sign to indicate which amphibian you are looking at, it’s the texture of their skin. Toads are warty-looking, covered in little lumps and bumps, while frogs are sleek and smooth. Toads also virtually always have dry skin, whereas frogs look wet even when they are out of the water.

Location

If you’ve spotted an amphibian making its way along a pavement or ambling through some grass, chances are it’s a toad. Toads cope much better with dry conditions than frogs, as their skin is more waterproof. Frogs lose moisture a lot more easily, and so are rarely seen too far away from water, which explains why they always look moist.

Legs

Frogs have long legs, longer than their head and body, which are made for hopping. Toads, on the other hand, have much shorter legs and prefer to crawl around rather than hop.

Explanation:

Answer:

1. color.

2. texture and or roughness. the rat will be smooth and the toad will feel rough against the skin.

3. growth/ size. rats can grow to be huge and toads tend to stay kind of small.

What differences would they expect to see in cancerous chicken cells?
A Cancerous chicken cells will spend more time in interphase.
b Cancerous cells will not complete all phases of the cell cycle.
c Cancerous chicken cells will complete mitosis in a shorter amount of time.
d Cancerous chicken cells and normal cells will have the same total time to complete the cell cycle.

Answers

Answer:C!

Explanation:

Cancerous chicken cells will complete mitosis in a shorter amount of time.

The difference they would expect to see in cancerous chicken cells is cancerous chicken cells will complete mitosis in a shorter amount of time. The correct option is c.

What are cancerous cells?

Cancerous cells are those cells that cause cancer in organisms. These cells are the converted form of normal cells. The normal cells are converted into cancerous cells by the means of mutagens.

The cell cycle is the cycle of the division of a cell. The cell divides itself and forms a new daughter cell. That's how a body increases the older cells to divide and produce new cells. The process is called mitosis.

Now, the normal cells divide at a constant and normal rate that is needed, but the cancerous cells divided abnormally and rapidly which cause tumor in the body.

Thus, the correct option is c. Cancerous chicken cells will complete mitosis in a shorter amount of time.
