<span> B. A mutation can result in a change of function. </span>Not all mutations can cause negative effects, but a single mutation is capable of causing profound effect on the physiology and cellular structure of organisms. It can alter the function of proteins causing permanent diseases.
Answer:
Ok
Explanation:
Molecules such as proteins, nucleic acids, and carbohydrates have an affinity for water and are called hydrophilic (“water-loving”). Lipids, however, are hydrophobic (“water-fearing”). Some lipids are amphipathic—part of their structure is hydrophilic and another part, usually a larger section, is hydrophobic. Hope this helped
Answer:
is one in which blood flows through two capillary beds before being sent back to the heart.
Explanation:
A portal system can be defined as a system of blood vessels having a capillary network at each end, meaning that the blood vessel starts and ends in capillaries, before finding its way back to the heart. The blood draining through the capillary bed flows via the larger vessel to supply the blood to the another structure's capillary bed.
Answer:
chloroplasts
Explanation:
chloroplasts
Photosynthesis takes place in chloroplasts; cell walls allow plants to have strong, upright structures; and vacuoles help regulate how cells handle water and storage of other molecules.
The best explanation for this unchecked population growth is that the predators are too few to slow down population growth of mussels. The environment limits population growth by changing birth and death rates. The factors affecting population size and growth include biotic factors such as food, disease, competitors, and predators and abiotic factors such as rainfall, floods, and temperature. Predators affect individual growth rates of surviving prey by acting to increase growth rate by thinning the density of prey populations, which releases survivors from competition.<span />
