Answer:
B. rr
Explanation:
Genotype- Is the genetic makeup of an organism.
An homozygous individual is one who has similar allele e.g AA
It could either be in dominant form(AA) or recessive form(aa)
An heterozygote individual has two different allele in its genotype e.g Aa
A dominant gene is a gene that expresses itself in the phenotype of an individual while a recessive gene is a gene that is not expressed in the phenotype.
The genotype for a white homozygous flower is WW while the genotype for homozygous recessive is ww.
The dominant genotype is usually denoted with capital letter and the recessive is denoted with small letter.
Answer:
Relative dating is the science of determining the relative order of past events.
Explanation:
Relative age dating determines whether one geological or paleontological event happened before or after a second event.
it is more efficient for the body and it gives them time to collect more
<h2>Problem of protein alters the movement of Ions </h2>
Explanation:
- Proteins are tiny machines that do explicit occupations inside a cell. The directions for building every protein are encoded in DNA. Proteins are gathered from building squares called amino acids.
- The CFTR protein is comprised of 1,480 amino acids. When the CFTR protein chain is made, it is collapsed into a particular 3-D shape. The CFTR protein is formed like a cylinder that experiences the film encompassing the cell, similar to a straw experience the plastic top on a cup.
- In individuals with CF, changes in the CFTR quality can cause the accompanying issues with the CFTR protein:
- It doesn't function admirably
- It isn't delivered in adequate amounts
- It isn't delivered in any way
- At the point when any of these issues happen, the chloride particles are caught inside the cell, and water is never again pulled in to the space outside the cell. When there is less water outside the cells, the bodily fluid in the aviation routes gets got dried out and thickens, making it smooth the cilia. The cilia can't clear appropriately when thick, clingy bodily fluid overloads them.
