In the Punnett square below what would be the genotype for the organism represented by box 2?

1.) bbss
2.) BbSs
3.) bbSs
4.)Bbss

Answers

Answer:

bbss

Explanation:

mitochondria is the powerhouse of a cell

The genotype for the organism is represented by box 2 - 1.) bbss.

Punnett square is a way to find the genotype of any trait either monohybrid or more than one allele. To predict the outcome of breeding experiments where one trait with two boxes and two traits are being followed and the Punnett square is larger, with sixteen boxes.

Each side has gametes, representing alleles they have, produced by each parent.Each box shows the zygote that has a genotype combination of the gametes.for instance, here bs is fused with bs which form the zygote that contains the genotype bsbs.

Thus, The genotype for the organism is represented by box 2 - 1.) bbss.

Why must cells divide to stay small or change shape to reduce volume?
O To diffuse substances from an area of higher to lower concentration
To ensure the cell is able to obtain nutrients or remove wastes.
To reduce surface area of the cell for quick movement.
O To move water molecules from areas of high to low pressure

Answers

Answer:

if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function. That is why cells are so small.

Explanation:

Answer:

To ensure the cell is able to obtain nutrients or remove wastes.

The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume That is why cells are so small.

thank you you're a lifesaver

Answers

Answer:

i dont want to do so much writing but i guess i will help

Explanation:

If photosynthesis came to an abrupt end, most plants would die within short order. Although they could hold out for a few days -- or in some cases, a few weeks -- how long they lived would largely be a factor of how much sugar they had stored within their cells. Large trees, for example, may be able to soldier on for several years — perhaps even a few decades — because of their energy stores and the slow rate of use. However, the majority of plants would meet a withering end, and so would the animals that rely on them for nourishment. With all the herbivores dead, the omnivores and carnivores would soon follow. Although these meat-eaters could feed on all the carcasses strewn about, that supply wouldn't last more than a few days. Then the animals that temporarily relied on them for sustenance would die.

If a nerve cell stopped functioning, the cell would


a. start producing oxygen.

b. begin dividing into more cells.

c. become a different type of cell.

d. stop sending signals to the brain.

Answers

Answer:

D

Explanation:

Only logical and possible solution

If a nerve cell stopped functioning, the cell would stop sending signals to the brain. Thus, the correct option is D.

What are the functions of a nerve cell?

The functions of a nerve cell are as follows:

It receives messages from all the different parts of the body. It plays an essential role in the transformation of messages to the brain. Nerve cells are also involved in commanding the different functions of the organs through the brain.

So, if nerve cells deal with the electrical impulses and transformation of information and messages from one part of the body to the another, they definitely do not deal with the production of oxygen, division of more cells, and become a different type of cell.

Therefore, stopping sending signals to the brain is an appropriate function of the cell, once a nerve cell stopped functioning. Thus, the correct option for this question is D.

Answers

Answer:

I'm not 100% sure but i think its A; let me know if this is correct.

Explanation:

C. Bacteria convert gaseous nitrogen into ammonia during the process of nitrogen fixation.

What is nitrogen fixation?

Nitrogen fixation is the process by which atmospheric nitrogen (N2) is converted into ammonia (NH3), which can then be used by plants and other organisms as a source of nitrogen for growth and reproduction.

This process is performed by specialized bacteria, such as those found in the nodules of leguminous plants, as well as other bacteria found in soil and water. The conversion of N2 into NH3 is an energy-intensive process, which is why nitrogen fixation is performed by only a few types of bacteria. The ammonia produced by nitrogen-fixing bacteria can be used directly by plants and other organisms, or it can be converted into other forms of nitrogen, such as nitrates and nitrites, which are also usable by plants.
