Water is reabsorbed during filtration by renal capillaries.
Answer:
Most of the solutes get reabsorbed in the PCT by a process called tubular reabsorption. In the loop of Henle, the filtrate continues to exchange solutes and water with the renal medulla and the peritubular capillary network. Water is also reabsorbed during this step.

what happens when the epiphyseal plate is ossified
Answer:
Bones grow in length at the epiphyseal plate by a process that is similar to endochondral ossification. When cartilage growth ceases, usually in the early twenties, the epiphyseal plate completely ossifies so that only a thin epiphyseal line remains and the bones can no longer grown in length.

Question 1(Multiple Choice Worth 2 points)(05.05 MC)How does the human immune system initially respond to a pathogen?
Immediately, the pathogen has been recognized:
Macrophages acts as the first line of defence by engulfing pathogens identified by antigens which will now present the antibody shape to a helper T cell.
The Helper T cells produce a signal to plasma and Memory B cells to yield antibodies that attach to the antigens. The cytotoxic cells that leads to cell death are activated by the helper T cells.
Antibodies helps to immobilize pathogen for macrophage to feed on.
if the pathogen comes back a 2nd time the memory cells helps in quick and efficient recovery by producing the specific B and T cells for the antigen.

What are macromolecules?Monomers are long chains of molecular subunits that comprise macromolecules, essentially polymers. Long polymers are present in proteins, carbohydrates, and nucleic acids. They are called macromolecules because of their large size and polymeric nature.
Macromolecules are able to speed up biochemical reactions, store and retrieve genetic information, provide structural support, and store fuel. The biological macromolecule is carbohydrates, lipids, proteins, and nucleic acids is an essential component of the cell.
Therefore, macromolecules are important for body function.

2. A volcano erupts 40 miles from an owl’s ecosystem. Ash from the eruption blocks sunlight over your ecosystem for several (7-10) months.
a. Explain what happens within the food web in the weeks that follow the eruption.
b. The ash clears and several more months go by. What do you think will happen to your ecosystem?
Answer:
a. Sunlight cannot penetrate through the ash clouds. thus photosynthesize won't occur. so the food chain will begin to collapse from the producer and primary consumer. owls will be out thinking that it's night. they will catch fish resulting in an imbalanced ecosystem. the aquatic population will decrease. then it's the doom days for owls. they will emigrate or will die.
b. the ecosystem will restore. that's how nature works.
The volcanic eruption destroyed the owl ecosystem because it prevented the sun's light from entering, so the food web of the ecosystem was destroyed because there was no food, and a new ecosystem will grow after many months.
What is the ecosystem?The ecosystem has both biotic and abiotic components, and there are many food chains and food webs present in the ecosystem, so the volcanic eruption harmed the ecosystem and killed the populations present, but after many months, when the ashes from the volcanic eruption are cleared, a new population will grow and a new community will be seen.
Hence, the volcanic eruption destroyed the owl ecosystem because it prevented the sun's light from entering, so the food web of the ecosystem was destroyed because there was no food, and a new community will grow after many months.

in the overall reactions of photosynthesis, the electrons from _____ are used to reduce _____.
In the overall reactions of photosynthesis, the electrons from water are used to reduce carbon dioxide.
During photosynthesis, electrons from water molecules are used to reduce carbon dioxide and fix it into carbohydrates while oxygen is produced as a result. The process happens with the help of radiant energy.
Even though the process of photosynthesis is a series of reactions that have been divided into light-dependent and light-independent, the overall equation of the process is written as:
[tex]6H_2O + 6CO_2 ---> C_6H_1_2O_6 + 6O_2[/tex]

B. What structures are missing from the root hair cells?
Answer:
The function of root hairs is to collect water and mineral nutrients that are present in the soil and take this solution up through the roots to the rest of the plant. As root hair cells do not carry out photosynthesis, they do not contain chloroplasts.
Explanation:
Mitochondria are missing from root hair cells.
Root hair cells are specialized plant cells found in the roots of plants. Their primary function is to absorb water and minerals from the soil. To achieve efficient absorption, root hair cells have evolved specific structural adaptations.
Root hair cells are elongated and have a large surface area due to their elongated projections called root hairs. This increased surface area enhances their ability to come into contact with the soil, maximizing water and nutrient absorption. However, due to their focus on absorption and their short lifespan, root hair cells exhibit some structural simplifications, such as the absence of certain organelles.
One notable organelle missing from root hair cells is the mitochondria. Mitochondria are the "powerhouses" of cells, responsible for generating energy in the form of ATP through cellular respiration. Since root hair cells are mainly involved in absorption rather than energy production, they have a reduced need for extensive energy generation. As a result, they don't require as many mitochondria as other cells that are highly metabolically active.
