Question:

I failed to find the options, but I will post the way by which you can construct Punnett squares.

Answer and Explanation:

First, you need to know both parental individuals´ genotypes. From these genotypes, you will get all the possible gametes for each parent, following the principle of simple segregation.

Then, by using a simple square, you will make the crosses. This is:

  • You will locate all the possible gametes of one parent on the top of the square
  • You will place all the possible gametes of the other parent on the left edge of the square.
  • Once you have done that, you will perform the crosses. You will look for the intersection between each parent´s gametes and place all the involved alleles in the intersection-box. These are the possible genotypes, and they will be written within the square.

In the attached files, you will find an example of the cross between two pure-breeding plants.

Do you think the challenge society faces with regard to feeding the world's growing population is an example of ecological carry
Minchanka [31]

Answer: Yes

Explanation:

Carrying capacity can be defined as the total number of members of the population of a species that an ecosystem can sustain in terms of providing resources in the form of food, shelter and others. When the resources are available in surplus then the population of a species increases exponentially but declines when resources become scarce. The human population is increasing tremendously all over the world this is supported by the resources like food, water, fossil fuels, air, minerals, and others. But some of these resources are decreasing due to overuse and may not be available in future to sustain the future generation.

Hershey and Chase used radioactive isotopes to label different parts of the phage. They grew one batch of phage in the presence
AlekseyPX

The sulphur would lable the capsule and the phosphorous the nucleic acid.

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

Hershey and Chase experiment included growing of the pages in two batches, one in presence of 35S and other in presence of 32P. They then infected bacterial cells with these phages, cleaned them and then centrifuge the cells to isolate the marked elements in bacterial cells.

This was done to isolate which part of the phage is actually infective. Sulphur being a part of the proteins will mark the capsule whereas DNA having the phosphate bridges will be marked by 32P.

Which of the following has the most potential of experiencing background extinction based on the natural disruption described?
Neko [114]

The option that has the most potential of experiencing background extinction based on the natural disruption is : ( C ) A species that will not grow during a specific season every year

<h3>What is Background extinction </h3>

Background extinction is the gradual extinction of species due certian environmental factors such as change in weather conditions, disease, competitive disadvantage and habitat loss.

A population that will not grow during a specific season every year will experiences a gradual extinction process while other options will experience a fast and sudden extinction process.

Hence we can conclude that the most potential of experiencing background extinction based on the natural disruption is :  A species that will not grow during a specific season every year.

The nervous system regulates breathing
Gwar [14]

Answer:

The respiratory centers that control your rate of breathing are in the brainstem or medulla. The nerve cells that live within these centers automatically send signals to the diaphragm and intercostal muscles to contract and relax at regular intervals.
