The answer depends upon whether the daughter cells are haploid or diploid. If the daughter cells are diploid, it's mitosis. If the daughter cells are haploid, it's meiosis.
The presence of dense microvilli in the epithelial cells of the proximal convoluted tubule enhances their ability to reabsorb substances from the filtrate. This structure is also called brush border epithelium.
<h3>What is tubular reabsorption?</h3>
The movement of water and solutes from the proximal convoluted tubule back into the bloodstream is called tubular reabsorption.
Water and solutes from the proximal convoluted tubule (PCT) are transported to the bloodstream in bulk and thus most of the reabsorption occurs via the PCT.
These tubules reabsorb about 60% of water and 90% of bicarbonate. They also reabsorb almost 100% of the glucose and amino acids.
This reabsorption takes place by two routes. First is the paracellular route in which solutes move between cells via the intracellular route. Second is the transcellular route in which solutes move through the cells.
Therefore, the structural modification helping the proximal convoluted tubule cells to enhance their ability to reabsorb substances from filtrate is the presence of microvilli.

Answer:
Photosynthesis is not taking place and carbon dioxide is not being processed.
Explanation:
The process by which plants make glucose (carbohydrates = energy stores) from carbon dioxide and water is called photosynthesis and uses sunlight energy. A by-product of photosynthesis is oxygen.So plants use water and sunlight to grow and they produce oxygen. Animals on the other hand eat plants, use oxygen and breathe out carbon dioxide.
Since the space station is in the shadow of the earth, the plants are unable to complete the process of photosynthesis and the carbon dioxide that is being produced by the humans cannot be utilized by the plants due to no sunlight. There for the carbon dioxide is going to continue to build up as the energy storage molecules are being depleted and not replenished.
<span>Condyloid joint
There are 6 types of synovial joints in the human body. For this question, the 2 types that are most likely are condyloid or ball-and-socket joints. Both of these joint types are very similar to each other, so let's look at them in detail to see which one is the correct answer.
Condyloid - Has an ovoid condyle from one bone fitting into an elliptical cavity. It permits movement in two planes, but does not permit rotation.
Ball-and-socket - A ball shaped surface of one bone fits into a cup shaped depression of another. This type of joint permits movement in multiple planes and rotation.
The key difference between these 2 joint types is the symmetry between them. For the ball and socket, the projection is shaped like a ball which is completely symmetrical whereas for the condyloid, the projection is more ellipsoidal or ovoid which prohibits rotation. And since ovoid is mentioned in the question, the best choice would be the condyloid joint.</span>
