Answer:

Endoplasmic reticulum is the defective organelle in most CF.

Explanation:

This is because of  mutation(deletion) in the proteins of these organelle. The CFTR  protein -a transmembrane regulator get stucked inside the E.R, thus  the  CFTR chloride protein channel is blocked. Therefore the outflow of Cl and water  out of the cell  is obstructed.

Consequently, the mucus from blocked fluid flow, clogs the lungs, the fallopian tube, sweat duct, and other places.

gavmur [86]

Greater force of contraction, volume of blood ejected, and cardiac output result in aerobically trained individuals with greater stroke volume compared to untrained individuals

<h3>What increases stroke volume?</h3>

A greater force of contraction consequently increases the volume of blood ejected with each systole (Systolic Volume). Increasing the stroke volume also increases, as a consequence, the cardiac output (CO = VS x HR).

With this information, we can conclude that greater force of contraction, volume of blood ejected, and cardiac output result in aerobically trained individuals with greater stroke volume compared to untrained individuals

This is true that The mutation rate would also be higher.

<h3>What is mutation?</h3>

A mutation is a change in the nucleic acid sequence of an organism's, virus's, or extrachromosomal DNA's genome. DNA or RNA can be found in the viral genome.

Environmental elements known as mutagens are what trigger mutations. Radiation, chemicals, and pathogenic agents are examples of mutagens. Mutations may occur naturally spontaneously.

Because it generates a new DNA sequence for a particular gene, the mutation is crucial in the initial stage of evolution because it results in the creation of a new allele. Through intragenic recombination, recombination can also produce a new DNA sequence (a new allele) for a particular gene.

Answer:

gametes

Explanation:

For any mutations to be passed down to offspring, they must occur or be present in the gametes. This is because gametes are the cells that fuse to make a zygote that develops into an organism. Somatic mutations are not transferable.
