<span>These are the sarcomeres. These are the long, fibrous proteins that allow muscles to contract as they do work. These proteins also give striated muscle their striped appearance. They are composed of two proteins: myosin and actin. Sarcomeres slide past each other as they are engaged or disengaged.</span>
Answer:
D. Einstein's theory was difficult for many people to understand.
Explanation:
Einstein’s theory of general Relativity was largely Ignored for three decades because scientists at the time thought the theory was too complex compared to Newton's.
Therefore, it took long before the general science community accepted Einstein's theory of general relativity because Einstein's theory was difficult for many people to understand.

Answer: Biological Mutations
Explanation: Through mutation and selection, bacteria can develop defense mechanisms against antibiotics. For example, some bacteria have developed biochemical “pumps” that can remove an antibiotic before it reaches its target, while others have evolved to produce enzymes to inactivate the antibiotic.
Answer:
single gene traits are generally not significantly influenced by the environment, whereas complex traits have a significant environmental component
Explanation:
Single gene traits that are controlled by a locus, that is two alleles of a trait controls the expression of a character. Single gene traits are said to be involved in Mendelian inheritance. These traits are not all significantly influenced by environmental factors. On the other hand, complex traits, such as height in humans, which is controlled by 10 or more allelic pairs, have been found to be significantly influenced by environmental components like diet. This explains why the expression of height in human population is widely varied, and when each individual’s height of a population is plotted on a graph, we would see a normal distribution curve with a bell curved shape.
