Show are meiosis and mitosis different

Answers

Answer:

The purpose of mitosis is the creation of diploid somatic cells and the purpose of meiosis is the creation of haploid sex cells.

Explanation:

Mitosis takes place in somatic, or body cells, and meiosis takes place in gametes, or sex cells.  The purpose of mitosis is growth and repair, while the purpose of meiosis is creating gametes with half the normal number of chromosomes and is for reproduction.  Mitosis goes through Interphase, Prophase, Prometaphase, Metaphase, Anaphase, Telophase, and Cyokinesis once to produce two genetically identical diploid somatic daughter cells.  Meiosis goes though that twice (Meiosis I and Meiosis II) to produce 4 genetically unique haploid gametes.  It has stages (Prophase, Metaphase, Anaphase, and Telophase) such as Prophase I and Prophase II because meiosis occurs twice.  Another difference is that mitosis happens throughout your life and meiosis occurs before females are born and throughout a males life.  

Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.

2. How do gene splicing and gene therapy differ? How are they alike?

Answers

Gene therapy and gene splicing are separate but linked processes. A new organism can be created by cutting and recombining genetic material from two separate sources, a process known as gene splicing.

What is gene splicing ?

It is a technique that scientists utilise in the lab to develop new organisms with desired features. On the other side, a healthy gene is introduced into the patient's cells during a medical process called gene therapy to treat diseases and disorders.

Gene splicing and gene therapy share certain similarities despite their distinctions. Both procedures entail the modification of genetic material, frequently derived from several sources, in order to produce the desired outcome.

The goal of gene splicing is the development of a new creature or its modification.that of an active organism. Treatment of a disease or disorder is the intended outcome of gene therapy. Both procedures also entail the manipulation of genetic material using specialised methods, such as recombinant DNA technology. Finally, for both methods to be effective, a good understanding of genetics is necessary.

The process involved in the formation of rains is option B, it warms the clouds in the sky and causes precipitation.

What is water cycle ?

Water cycle is a geological phenomenon through which the water content in the atmosphere and hydrosphere is balanced. The heat radiated from sun warm up the water bodies make the convection currents that evaporates water.

The water vapor rise to the atmosphere and maintain the air moisture. When this vapor cools down they condense and precipitates as rain, snow or sleek.

This process involves the transfer of heat energy and matter. Here, the matter is water itself with its three phases.  Hence, option b describes the cause of rain.

Jill uses a magnet to pick up a nail. Then, she touches the nail to a paper clip and picks up the paper clip. What will most likely happen when she pulls the magnet away from the nail?

The paper clip will stay attached to the nail because the nail is now a permanent magnet.
The paper clip will stay attached to the nail because the paper clip is now a permanent magnet.
The paper clip will fall off of the nail because the nail was only a temporary magnet.
The paper clip will fall off of the nail because the nail is now magnetized in the opposite direction.

Answers

Answer:

C but see below.

Explanation:

e. The paper clip will likely fall off because it wasn't attached to the nail long enough to be magnetized.

The same answer would apply to the nail. It likely was not held onto the magnet long enough to pick up a magnetic force that would be strong enough to overcome the gravitational force pulling on the clip.

Answer:

ty for helping me now ill help you

a

Explanation:

cytokensis is the physical process of cell division. It divides the cytoplasm of a parental cell into two different daughter cells.

In plants, a cell wall forms. Cytokensis occurs in mitosis and meiosis. The objective for cytokensis is to divide the parent cell into two daughter cells. So cytokensis in plants is when a cell wall forms in between the daughter cells. Plant cells have walls, so they CANNOT divide using a cleavage furrow. A cell plate forms across the cell during telophase.

In animal cells, cleavage furrow forms. This pinches the cell in half and forms two different cells.

why CO2 still being produced for a few minutes after death?

Answers

Explanation:

As best as anyone can gauge, cell metabolism likely continues for roughly four to 10 minutes after death, depending on the ambient temperature around the body.

During this time period, oxygenated blood, which normally exchanges carbon dioxide with oxygen, is not circulating. Thus, cell respiration—which uses oxygen to make cellular energy while creating carbon dioxide as a by-product—creates carbon dioxide that is not transported out of the cell. This lowers the pH of the cell, resulting in an acidic intracellular environment. This acidic environment causes intracellular membranes to rupture—including those around the cell's lysosome, which contains enzymes for digesting everything from proteins to fats and nucleic acids. Once the membranes have burst, these enzymes are released and begin to digest the cell from the inside out. This process is known as autolysis (or self-digestion).

In chickens, Black feathers (B) are dominant over white feathers (b). Complete the Punnett

What percentage of offspring will be Black?
What percentage of offspring will be White?

Answers

Answer:

(attached Punnett square below)

100% of the offspring will have black feathers

0% of the offspring will have white feathers

Explanation:

All the possible offspring have the genotype Bb, and since B (black) is dominant it will be the phenotype regardless of the presence of a b allele.

Therefore, all the offspring will be black (100%) and since none of the genotypes are bb there's no chance for white feathered chickens (0%)

Mendel wanted to find out if the pattern of inheritance for one trait affected the pattern of inheritance for another. What experamint did he perform to test this idea

Answers

Answer: He performed dihybrid crosses

Explanation:

Dihybrid cross is simply refered to as a cross that is done for two genes that are different with regards to their traits. For example, if we cross two maize plants which have different shapes and color let's say that one is white and round while the other maize's colour is yellow and its shape is wrinkly.

Since Mendel wanted to find out if the pattern of inheritance for one trait affected the pattern of inheritance for another, the experiment performed will be dihybrid crosses.
