The type of growth that a population may show when food and habitat are limitless is called?

saul85 [17]

A type of growth that a population may show when food and habitat are limitless is exponential population growth.

<h3>What is exponential population growth?</h3>

The case in which resources are limitless a population can experience exponential population growth where the size increases at a greater rate.

Exponential growth occurs when there is large quantity of resources are present and few individuals are there to utilize it

When number of individuals increases the resources will depleted and growth rate will slow down.

Therefore, exponential population growth is the type of growth in which resources are plenty in comparison of population.

Answer: The combination produced is RRtt.

The combination rrTt does not appear in this punnett square.

Explanation:

As the problem does not indicate more information, I assume that punnett square is made between two RRtt genotypes. It can produce gametes that have the alleles Rt. A gamete is a sexual cell (egg or sperm) that has only one allele of each gene. And, each gamete codes for a different gene. Since here we have two different types of alleles (R and t), it is a dihybrid cross.

<u>A Punnett square is a diagram used to predict the genotypes of a cross or breeding experiment.</u> It is used to determine the genotypes and phenotypes of the offspring. To do it, you have to label the rows with one parent's gametes and label the columns with the other parent's genotype. Then, have each box inherit letters from its row and column, and interpret the results.

Then, the punnett square (shown in the picture) will be between RRtt and RRtt whose gametes can only be Rt, so Rt x Rt will be made.

The result in an offspring which will be 100% RRtt, and there is no rrTt combination here because non of the parents have an r allele, then none of the children can inherit it.

To have an offspring where rrTt genotype is shown, a different genotype must be used, in which both parents must have at least one r allele and one t allele. For example, it could be Rrtt x rrTt.

Secretors (genotypes ss and ss) secrete their a and b blood group antigens into their saliva and other body fluids, while nonsec

Solnce55 [7]

As you can see from the image presented below when parents with AB Ss and AA ss genotypes cross we get three distinct phenotype groups.
Marked in red are the individuals whose A type blood we can determine from the saliva because they have at least one S allele.
Marked in light green are the individuals whose AB type of blood we can determine from the saliva too.
And marked in orange are the individuals that are homozygous recessive for the s allele, and we could not determine their blood type from their saliva.

Animals eat plants and produce carbon dioxide and water. How do animals affect the amount of carbon in Earth's atmosphere?

mrs_skeptik [129]

They do the same thing that all living and breathing things do! They breathe! When they breathe they are doing the same thing you are doing all day everyday. Inhaling oxygen and exhaling carbon dioxide.

Research and produce a summary about the history of the microscope.

svetlana [45]

Microscopes have been used for centuries in order to see specimen scientists cannot see with their unaided eye. Antón VanLeeonhoeuk is given credit for designing the first lenses for microscopes in the 16th century. He looked at “animacules” which we would now call bacteria and protists. Robert Hooke first coined the term cell, as he looked at cork and thought it looked like cells that monks slept in. Improvements were made in the following centuries, and Ernest Leintz in the 1800s creates a way to have differing magnification lenses on one microscope. Continuing into the 1900s and 2000s there are now electron scanning microscopes, ultraviolet microscopes, atomic force microscopes, and electron tunneling microscopes—all which allow scientists to have better resolution and to see smaller and smaller things. Microscope technology will continue to improve as scientists discover more ways to magnify the microscopic world.
