Answer:
Frequency of the allele "r"causing the disease on Tristan da Cunha
%
Frequency of the allele "r"causing the disease in the original population of 15 colonists 
%
Explanation:
Frequency of the allele "r"causing the disease on Tristan da Cunha
Given -
Out of 240 descendants on the island, 4 had retinitis pigmentosa (rr).
As per Hardy Weinberg's equllibrium equation
The frequecy of recessive individual in a given population is represented by 
And q represents the frequency of allele r
So, in this case q is equal to
%
Frequency of the allele "r"causing the disease in the original population of 15 colonists
As it is given in the question statement , the frequency of allele "r"causing the disease in the original population of 15 colonists is ten times the frequency of the allele "r"causing the disease on Tristan da Cunha
i.e
%
Truncating mutations in TTN, the gene encoding the titin protein, cause 15 to 25% of nonischemic dilated cardiomyopathy (DCM), however it is unclear whether this is due to haploinsufficiency or the presence of truncated titin proteins.
<h3>
What is TTN gene?</h3>
The TTN gene codes for the production of titin, a massive protein. This protein is crucial in both the muscles used for movement (skeletal muscles) and the heart (cardiac muscle). Different muscles produce somewhat different copies of titin (known as isoforms).
Titin is a necessary component of structures called sarcomeres within muscle cells. Sarcomeres are the fundamental components of muscular contraction; they are composed of proteins that produce the mechanical force required for muscles to contract. Titin has numerous purposes within sarcomeres. One of the primary functions of the protein is to provide shape, flexibility, and stability to these cell structures. Titin interacts with other muscle proteins, such as actin and myosin, to maintain sarcomere components in place while muscles contract.

Fossil hunters can be good stewards by respecting the area around the dig site. Instead of getting big machinery to do the dig and ruining the area around the fossil, they can instead be careful in obtaining the fossils.
Answer:
photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
The roots absorb water and minerals from the soil and anchor the plant in the ground. The stem supports the plant above ground, and carries the water and minerals to the leaves. The leaves collect energy from the Sun and make food for the plant, using an amazing process called photosynthesis.
