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]

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.

Construct an explanation for that carbon hydrates are considered as a source of energy for the human body. Justify your answer with an evidence with your own words.
Please help out I’ll mark as brainlist
Explanation: Carbohydrates are mainly composed of Oxygen, Carbon and Hydrogen. the most popular carbohydrate that is compatible with the human body is glucose which is the final result of every Carb we take in. a glucose molecule has 6 carbon atoms. during glycolysis, a single glucose molecule is broken down into two pyruvate molecules. in there, the first couple of ATP is synthesized. at later steps of the cycle, more ATP molecules are reduced.
The movement of water across a cell membrane that does not require
energy is called what?
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.
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.

Which statement about the balanced equations for nuclear and chemical changes is correct? (1 point) Both are balanced according to the total mass before and after the change. A chemical equation is balanced according to mass number. A nuclear equation is balanced according to the total mass before and after the change. Both are balanced according to the mass number of each element before and after the change. A nuclear equation is balanced according to mass number. A chemical equation is balanced according to the total mass before and after the change.
Both nuclear and chemical equations are balanced according to the total mass before and after the change.
In every equation or reaction, the total mass of the reactants must be equal to the total mass of the products. In other words, all reactions - be they chemical or nuclear - must obey the law of conservation of mass.
The law of conservation of mass states that mass can neither be created nor destroyed, but can be converted from one form to another during a reaction.
Thus, in order to balance reactions involving chemical or nuclear reactants, the total mass before the reaction must be equal to the total mass after the reaction.
More on the law of conservation of mass can be found here: https://brainly.com/question/13383562
Answer:
A nuclear equation is balanced according to mass number. A chemical equation is balanced according to the total mass before and after the change.

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.
