Explanation:
People who experience severe blood loss go into a condition known
as hemorrhagic shock. Shock occurs when the blood volume
returning to the heart is reduced. The heart responds by trying to
increase output, which can result in the patient bleeding to death if
he or she is not treated in time. Is this an example of negative
feedback or positive feedback? Explain your answer.

Positive
Explanation:
Bodies way of trying to heal/get rid if the problem it self.
Consider the scenario.
A scientist sets up an experiment to see how sugar in the diet of
rats affects their weight. The scientist feeds one group of rats a
diet high in sugar, another group a diet of moderate sugar levels,
and a third group a diet low in sugar.
All of the rats in the experiment are the same species and age
and start the experiment at a healthy weight. The rats also
receive the same kind of sugar.
What is the independent variable?
A. amount of sugar
B. weight of the rats
C. age of the rats
D. type of sugar
The dependent variable is affected by the independent one. The amount of sugar (heigh, moderate, low) is the independent variable. Rats weight is the dependent variable.
What are the dependent and independent variables?Independent variables are those modified or changed by the researcher to study how this change affects another variable and hence the results.
This variable is not affected by any other one but influences or causes a reaction in other variables.
The dependent variable is the one influenced by the independent variable, and is affected by any change on this last one.
Its response might be either directly proportional or inversely proportional to the change in the independent variable.
In the exposed example,
Aim of the experiment: to see how sugar in the diet of rats affects their weight.Independent variable: Amount of sugar (high, moderate, low)Dependent variable: Rats weightControl variables: Type of sugar, initial weightThe amount of sugar (independent variable) that was provided to rats will affect or influence their weight (dependent variable).
So, rats weight will change according to the sugar they get in the diet.

. How do the parent guinea pigs and their pups provide evidence that support Mendel's conclusion about inheritance?
The guinea pig is a small, domesticated rodent native to South America. Humans domesticated this species somewhere about 5,000 B.C., perhaps from the Montane Guinea Pig.
The domestic version, sometimes known as "Cavies," is a separate species today. They are frequently kept as pets in homes and are typically well-liked because to their docility and love to people. Continue reading to learn more about the Guinea Pig. These rodents are quite little, with tiny ears, short legs, and no tail. Cavies normally weigh one to two pounds and are eight to nine inches long.
Animals with a variety of colors and coats have been painstakingly produced by humans. Therefore, instead of being white, cream, grey, black, orange, or any combination of the aforementioned hues, these little rodents are brown.

what is the maximum initial reaction rate for the enzyme at ph7
At pH 7, this enzyme's maximal initial reaction rate is 350 X 10>6 per minute of product produced with a saturation of 2–4g of substrate.
An enzyme-catalyzed reaction has a very productive relationship between the substrate concentration and the starting reaction, but the pH of the supplied solution has a significant impact on this relationship. pH7 has the highest rate of productivity.The connection is roughly linear with respect to substrate concentration and pH level up to the saturation point, which in this case was attained between 2g and 4g of substrate.Up until the point of saturation, which in this instance is between 2g and 4g of substrate, the reaction is more productive with increasing concentration. Beyond that point, adding more substrate has no extra benefit.Learn more about the effect of pH on reaction rate here:

more than expected.
Although the total distance the impulse travels in the reflex arc is less than 3 meters. the time taken is more than 0.04 seconds and the time taken is more than expected because of Synapses or due to gaps between neurons.
Diagram displays the whole reflex arcs from the tip of the finger to the spinal cord and then back out to a closer muscle, possibly in the forearm or the arm. Because the signal doesn't have to go all the way back to the finger, the total distance is less than 3 meters. Considering that it just travels back a portion of the way, less than 3 meters, it takes. Let's see, it takes more than twice as long, therefore the query makes us think about why the delay. Where is the hold-up what is happening there, and the key to this is that the gray matter of the spinal cord doesn't truly contain mylin, despite the fact that we said it- accelerates electrical conduction through the axon in the nerves of the extremities. Mylin has a whitish color, which contributes to the white matter's appearance of whitishness. Thus, the electrical signal becomes slower.

lonic bonds form between ionized atoms.
Ionic bonds, also known as electrovalent bonds, are a type of linkage created in a chemical molecule by the electrostatic attraction of ions with opposing charges. When the valence (outermost) electrons of one atom are permanently transferred to another atom, a bond of this kind is created. If an atom gains electrons, it becomes a negatively charged ion (cation), while if it loses them, it becomes a positively charged ion (cation) (anion). Following is a quick discussion on ionic bonds. Ionic or electrovalent compounds are produced via ionic bonding, and the compounds generated between nonmetals and alkali and alkaline-earth metals serve as the best examples of this type of compound.

all chemical processes which take place in living cells ??
Biochemical reactions are chemical processes that occur within living organisms.
Chemical processes known as "biochemical reactions" happen within the cells of living beings. The study of biochemistry shows that understanding both chemistry and biology is necessary to comprehend how cells function in living things at the level of the organism. Metabolism is the collective term for all biological processes that occur within an organism. Both exothermic and endothermic reactions are a part of it.
Catabolic reactions are exothermic processes that occur within living things. These processes disassemble molecules into smaller parts while also releasing energy. The breakdown of glucose is an illustration of a catabolic reaction, which releases the energy required by cells for their vital functions. Anabolic reactions are endothermic processes that occur within living things. These processes combine tiny molecules into larger ones.
A biochemical reaction is the transformation of 1 molecule to a one-of-a-kind molecule inside a mobile. Biochemical reactions are mediated through enzymes, which might be biological catalysts which could alter the rate and specificity of chemical reactions internal cells.
Photosynthesis, gluconeogenesis (synthesis of glucose from non-carbohydrate resources, specifically used by the brain), protein biosynthesis, fatty acid synthesis, glycolysis, Krebs cycle, urea cycle, glycogenolysis are some common examples of biochemical reactions.

During this phase, reactions require oxygen?
All three phases of respiration are used in the breakdown of carbohydrates (glycolysis, citric acid cycle, and the electron transport chain).
No oxygen is needed for glycolysis. All cells, including anaerobic cells that are killed by oxygen, engage in this anaerobic kind of respiration. When there is insufficient oxygen, your muscle cells additionally add a fermentation phase to the glycolysis process. Pyruvate is changed into lactate by them.
Aerobic refers to cellular respiration processes that need oxygen.
The only metabolic process indicated that specifically requires molecule oxygen is the electron transport mechanism. One of the most electronegative elements in human bodies, oxygen serves as the final electron acceptor in the electron transport chain.
