Answer:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
Excitatory postsynaptic potentials are generally caused by __________ channels opening, while inhibitory postsynaptic potentials may be caused by __________ channels opening.
Answer:
Na+,Cl-
Explanation:
Excitatory postsynaptic potentials are generally caused by Na+ channels opening, while inhibitory postsynaptic potentials may be caused by Cl- channels opening.
Excitatory postsynaptic potentials are generally caused by sodium channel opening, while inhibitory postsynaptic potentials may be caused by chloride channel opening.
What are postsynaptic potentials?Changes in the membrane potential of the postsynaptic terminal of a chemical synapse are known as postsynaptic potentials. Despite having the ability to start or stop action potentials, post-synaptic potentials are graded potentials and shouldn't be mistaken for them.
When sodium channels open in response to a stimulus, an excitatory postsynaptic potential (EPSP) takes place. As a result of the electrochemical gradient, sodium floods the cell.
Therefore, chloride channel opening in the postsynaptic membrane results in inhibitory postsynaptic potentials, whereas sodium channel opening results in excitatory postsynaptic potentials.

If an animal cell is placed in plain water, It will swell and burst. The bursting of the cell is a result of which biological process
Answer:
Osmosis is the process of having water pass from a low concentration medium to a high concentration one, given that the barrier (membrane) is semi-permeable.
Explanation
Cells encounter osmosis due to their semi-permeable membranes. Water can flow past cell membranes. A given cell placed into distilled water will have some water flow into it, causing it to burst. A given cell placed in a very concentrated water will have some water flow out of it, causing it to shrivel. A given cell placed in a solution with the same concentration of minerals as the cell will have an equilibrium of water flowing in and out. This is the case of IV (Intravenous therapy) when we want to deliver substances into a human blood. We want to make sure the liquid delivered is as concentrated as the blood to avoid cell shriveling or bursting.
This picture above sums up the 3 cases cells could face in a solution.

What level of protein structure includes polypeptide aggregates?.
Answer:
Quaternary Protein Structure
Explanation:
It's a tri structure made up of two or more separate polypeptide chains that work together to form a single functional unit. The – anti interactions and disulfide bonds that stabilize the resultant multimer are the same as in the tertiary structure.
The level of protein structure that includes polypeptide aggregates is the quaternary structure.
Quaternary structure refers to the arrangement and interactions of multiple polypeptide chains to form a functional protein complex.
These individual polypeptide chains, also known as subunits, come together through various non-covalent interactions such as hydrogen bonds, ionic bonds, and hydrophobic interactions.
The resulting complex may consist of identical or different subunits, and their arrangement is critical for the protein's overall function.
Quaternary structure is essential for proteins with multiple functional domains or when a cooperative effect is needed for the protein to perform its specific biological role effectively, such as in enzymes, antibodies, or hemoglobin.

In a cactus thorn size is an inherited trait. B= long thorns and b=short thorns. A pure bred long-thorn plant was crossed with a hybrid medium-thorn plant. What percent of the plants have short horns?.
A: 100%
b: 75%
c: 25%
d: 0%
e: 50%
The percent of the plants that have short horns in a cross between a purebred long-thorn (BB) plant and a hybrid medium-thorn (Bb) plant is 0% (Option d). It is a case of codominance.
Aleleles and codominanceAn allele is a specific gene variant, diploid organisms inherit two alleles for each gene locus.
A heterozygous individual carries two different alleles for a given gene locus.
In codominance, both alleles are equally expressed in heterozygous individuals.
In this case, the long-thorn allele will be always inherited almost one time because one parent is BB.

What do genes do and how do they work?
Answer:
Genes are basically what makes us look the way we do or something like that. They are made up of DNA. Your genes sort of tells your cells to make molecules called proteins, which help your body function. Your genes also carry information that determines your traits which goes back to what I said about them making up the way you look. Your genes are basically like a cookbook recipe for DNA. Genes tell your cells what to do and when to do it. They are sometimes called "blueprint for life."
