Answer:
Because the shape helps to keep the composition of blood in the body balanced to maintain good health.
Explanation:
The kidneys are two 'bean-shaped' organs in the lower back that serve to conserve water, maintain blood osmolarity, help in acid-base balance, and filter blood plasma. Urine is the fluid product produced by the kidneys which is excreted as waste from the body.
For Anna’s case, my preliminary idea of the species of bacteria
responsible for Anna’s infection is a Gram-negative bacterium as observed in gross examination of the
colony. With this, my <span>idea has not changed since the last activity for the bacteria was
rod-shaped when we view it through a
microscope and the color of the colonies was
pink after we Gram stained it, which indicate that it is Gram-negative.</span>
<span>Factors that can increase mutation rates are high and low temperatures, food additives, and UV rays. All of these answers are correct. Mutation rates in genes vary depending on many environmental effects. UV rays, along with varying temperatures, can cause mutations during cell division due to the damage they impart on the cells that are dividing. Dangerous food additives are believed to cause mutations, as seen in animal studies (ie. aspartame causing cancer in rats).</span>
