Answer:
Please find the explanation below
Explanation:
This question is describing the processes involved in photosynthesis. In the light-dependent stage of photosynthesis, specifically photosystem II (PSII), water is oxidized in a process called PHOTOLYSIS OF WATER. This process produces electrons and Hydrogen ions (H+). The electrons produced via this process is accepted by NAD+ to yield NADH.
The NADH is an electron carrier produced during the light-dependent stage and used to reduce 3-phsophoglycerate (PGA) produced in the light-independent stage to glyceraldehyde-3-phosphate (G3P).
The oxidation of water in photosystem II of the light-dependent reactions is connected to the synthesis of glyceraldehyde-3-phosphate in the light-independent reactions.
In photosynthesis, the oxidation of water in photosystem II of the light-dependent reactions is connected to the synthesis of glyceraldehyde-3-phosphate in the light-independent reactions. In the light-dependent reactions, photons of light strike photosystem II and excite electrons, which then pass through an electron transport chain, leading to the production of ATP and NADPH. The ATP and NADPH generated in the light-dependent reactions are then used in the Calvin cycle to power the synthesis of glyceraldehyde-3-phosphate from CO₂.

Coelomates are animals which body cavity (coelom) is filled with fluid. Fluid surrounds organs, protects them and allows their free movement and growth. All vertebrates and some invertebrates, such as mollusks, annelids, and arthropods, are coelomates.
Answer:
a.) ventilation, circulation, cellular respiration
Explanation:
a.) ventilation, circulation, cellular respiration
b.) diffusion in tissues, cellular respiration, diffusion at respiratory surface
c.) ventilation, diffusion in tissues, circulation
d.) circulation, cellular respiration, diffusion in tissues
e.) circulation, ventilation, cellular respiration
Ventilation occurs in the lungs and is the process by which carbon dioxide in the capillaries is lost to the environment while oxygen is taken in. Circulation is the process by which this dissolved oxygen is taken by the blood to tissues around the body. When this oxygen is taken to tissue, the concentration gradient allows the oxygen to be taken up by tissue. This oxygen is used as an electron acceptor (when it reduced to water) in the mitochondria during electron transport chain of cellular respiration.
B) DNA replicates before the division.
C) the daughter cells are diploid.
D) homologous chromosomes synapse.
E) the chromosome number is reduced.
Meiosis II is similar to mitosis in that A- sister chromatids separate during anaphase, whereas homologous chromosomes separate during meiosis I. Unlike meiosis I, meiosis II does not involve DNA replication before the division.
Meiosis II is similar to mitosis in that sister chromatids separate during anaphase. During anaphase II of meiosis, the sister chromatids, which are identical copies of each other, move to opposite poles of the cell, just like in mitosis. This separation ensures that each daughter cell receives a complete set of chromosomes.
This statement is in contrast to meiosis I, where homologous chromosomes separate during anaphase. Homologous chromosomes are pairs of chromosomes, one from each parent, and separating them during meiosis I results in genetic variation.
Additionally, meiosis II, similar to mitosis, does not involve DNA replication before the division. DNA replication occurs in meiosis I, but during meiosis II, the sister chromatids that were formed in meiosis I remain intact and separate without any further DNA replication.

Answer:
ATP acts as source of energy in several cellular and physical processes happening within the body.
Explanation:
The major functions of Adenosine Tri Phosphate (ATP) are –
a) ATP provides energy for cellular metabolic processes.
b) ATP assists in active transportation of macromolecules across the cell against the concentration gradient.
c) ATP functions in both extra and intracellular signaling by releasing itself from synapses and thereby modulates calcium and cyclic AMP level inside the cell.
d) Maintain the structure of the cell
e) Provides energy for muscle contraction by binding to the myosin
