The water molecule its going to break and its OH group attaches to the phosphate that is removed from the ATP.
What is hydrolysis?Hydrolysis is when a water molecule reacts with another macromolecule and it hydrates. What happens then is that the water molecule splits and releases an OH and the other part of the H2O is going to join the molecule forming part of the new chemical bond.
In ATP hydrolysis, the chemical bonds of ATP, which are high-energy bonds, are broken, resulting in the formation of ADP and an inorganic phosphate, which is to which the OH binds.
ATP hydrolysis occurs when energy is needed for a reaction, since ATP bonds have a lot of energy. It is used in many processes in the body, such as muscle contraction, transport of substances against a gradient.
Therefore, we can confirm that the water molecule its going to break and its OH group attaches to the phosphate that is removed from the ATP.

During meiosis, non-sister chromatids may exchange sections of dna leading to genetic diversity. What is this process called?.
During meiosis, non-sister chromatids may exchange sections of DNA leading to genetic diversity due to (A) crossing over process.
The earliest source of genetic diversity in the meiotic nucleus comes from crossover events. A paternal chromosome and a maternal chromosome swap comparable DNA in response to a single crossover event between homologous non-sister chromatids. Now, that sister chromatid will contain some DNA from one parent of the person and some DNA from the other parent when it is inserted into a gamete cell. A combination of maternal and paternal genes that didn't exist before the crossover can be found in the sister recombinant chromatid. The result of multiple crossovers in a chromosomal arm is the same—exchanging DNA fragments to produce recombinant chromosomes.
There is a chromatid crossover between homologous chromosomes' non-sister chromatids. The genetic material exchange between homologous chromosomes is the outcome.

sea urchins are deuterostomes, which exhibit indeterminate cleavage in their development. if during growth of the embryo, one cell were to separate from the rest of the embryo, what would be it's fate?
Since sea urchins being deuterostomes, possess indeterminate cleavage, the separation of one cell from rest of the embryo will result in its growth into genetically identical embryo.
Deuterostomes are those species in which the formation of anus occurs before the formation of their mouth. The anus is formed from the blastopore in them. Deuterostome literally means second mouth. Example of such animals is: starfish, sea urchin, sea lily, sea cucumber, etc.
Indeterminate cleavage is the one where the cells of embryo possess the ability to give rise to complete embryo is they are separated from the actual embryo. Therefore, the cells are said to be totipotent.

which channel type triggers the rapid depolarization phase of the autorhythmic cell action potential?
The fast sodium channel triggers the rapid depolarization phase of the autorhythmic cell action potential.
Rapid sodium influx causes depolarization and reversal of the membrane potential inside the cell from negative to positive. Depolarization is an all-or-nothing event in neurons that is initiated by the opening of sodium ion channels within the plasma membrane. Repolarization, the subsequent return to resting potential, is mediated by the opening of potassium ion channels.
Autorhythmic cells lack a resting membrane potential, which drifts and changes as a result of ionic movement. Hyperpolarisation causes voltage-gated sodium channels known as funny channels to open, allowing [tex]Na^{+}[/tex]Na+ into the cell.

If the nerve endings of a mammalian heart were severed, the muscles of the heart would not stop contracting, but their rate of concentration changes.
How are nerves supplied to the heart?
The heart’s nervous supply is autonomic. It has parasympathetic and sympathetic parts both.
Sympathetic system: It acts on the sinoatrial node, dashing up the change rate, and thereby the heart rate increases.
Parasympathetic system: It works in reverse, which slows down the heart rate. The heart contains a natural pacemaker (sinoatrial node) which is why a nervous supply is not required. If the nerves to the heart are severed, then it'll still beat. As a matter of fact, it will beat quicker than normal, since there's commonly a parasympathetic supply that is slowing the heart down.

throughout the 1920s, otto meyerhof, a. v. hill, and colleagues investigated how cells use energy to power muscle contraction. they determined that during muscle contraction, glycogen is broken down into lactic acid, a product of fermentation. originally meyerhof thought that the conversion of glycogen into lactic acid directly powered muscle contraction. this idea was overturned by experiments performed by einar lundsgaard. what evidence did lundsgaard provide to suggest that glycogen breakdown and lactic acid production did not directly power muscle contraction?
After fermentation inhibition, muscle contraction could continue for a while.
What was his evidence?
It was shown by Lundsgaard that muscles still contract when in glycolysis, the formation of lactic acid is inhibited by the use of iodoacetate pharmacologically.
He also showed that during muscle contraction, pcr gets broken down and the breakdowns extent is proportional to tension created. On the idea of those experiments, Lundsgaard cautioned that the breakdown of PCr changed into the number one energy‐presenting response and this is what initiated the lactate‐forming reactions which regenerated PCr.

describe the brain mechanisms associated with circadian rhythms, and discuss how they may become desynchronized.
Circadian rhythms are 24-hour cycles of changes in the body, brain, and behavior. These natural processes, which primarily respond to light and darkness, have an effect on the majority of living things, including animals, plants, and bacteria.
A biological clock, or general coordinator, which regulates circadian rhythms is housed in the suprachiasmatic nucleus (SCN), a small group of cells in the hypothalamus. The SCN can react to variations in light and darkness because of neural pathways that relay information from specialised receptors in the rear of the eye. The brain and body then adjust to these changes as a result of the messages the SCN then sends out. Hormone and neurotransmitter fluctuations are controlled by the SCN, which in turn receives feedback that influences how the SCN functions. Melatonin, one hormone, aids in maintaining the biological clock's alignment with the light-dark cycle. When travelling by plane across numerous time zones, people frequently experience internal desynchronization. It is a condition in which biological rhythms are not synchronised.

Air does not mix in the lungs of birds; instead, it moves unidirectionally over the surface of the lungs to increase diffusion.
Similar to how a bird has air sacs throughout its body. Therefore, these sacs likewise swell when birds inhale air. Additionally, unlike avian lungs, which are static, air sacs are both anterior and posterior in nature. That is, they remain still.
