In erythroblastosis fetalis, only pregnant women who are ____ must be treated with injections to prevent their antibodies from attacking their baby s red blood cells
Answer:
Rh-negative
Explanation:
Erythroblastosis fetalis is a clinical condition whereby maternal antibodies begin to attack the fetal red blood cells due to incompatibility in the Rh of mother and fetus. Rh, which stands for Rhesus factor, can either be positive (Rh+) or negative (Rh-).
However, this condition (erythroblastosis fetalis) occurs in mothers/women who are Rh-negative. When an Rh- mother carries a fetus that is Rh+, the antibodies in the white blood cells of the mother identifies the blood cells of the fetus as FOREIGN, hence, begin to attack it.
However, one preventive measure is that pregnant women who are Rh-NEGATIVE must be treated with injections called Rh immunoglobulin to prevent their antibodies from attacking their baby's red blood cells.

water breaks down into what 3 things during the light reactions
The process in which water is broken down during the light dependent reactions is called photolysis.
Reaction
H₂O-->1/2O₂+2e⁻+2p⁺
Atomic oxygen is released from the water molecule and reacts with another atomic oxygen to form molecular oxygen(O₂)
The hydrogen atom has only one proton and one electron so one hydrogen atom can be written as(e⁻+p⁺) in the water molecule 2 hydrogen atoms are present so there will be 2e⁻+2p⁺
Therefore the three things that result from photolysis are:

How would the cycle be different if there were no water on earth?
Answer:
What I expect would happen: First, there would be no clouds. Lack of clouds would mean there would be no rain and the average temperature of the Earth would increase, resulting in large areas of land becoming desert.
Explanation:
The water cycle is the process where water falls as rain, is transported via rivers and streams to lakes and oceans, evaporates into the sky, condenses into clouds, and falls as rain again. Here's a diagram:
water.usgs.gov
water.usgs.gov
So what would happen if there were no condensation stage?
The condensation stage is the one where water vapour gathers together into clouds (and when the clouds become heavy enough with vapour, release water as rain). So the first answer is that there would be no clouds.
Without clouds, I foresee a few things happening:
From clouds come rain. With no clouds, there would be no rain.
Clouds move moisture from lakes and oceans (where it evaporates up) to mountains and other places inland that spark rainfall. And so vast stretches of land would become desert.
Clouds reflect sunlight and help cool the Earth. With no clouds, the average temperature of the Earth would increase significantly.
And so to summarize what I expect would happen. First, there would be no clouds. Lack of clouds would mean there would be no rain and the average temperature of the Earth would increase, resulting in large areas of land becoming desert.
Explanation:
During DNA replication, a complementary strand of DNA is made for each original DNA strand. Thus if a portion of the original strand is tcga actca, then the new strand will be
Answer:
agcttgagt
Explanation:
DNA is a double helix molecule composed of two complementary DNA strands which are in turn composed of four different nucleotide bases: Adenine (A), Guanine (G), Cytosine (C) and Thymine (T). In the DNA molecule, G and C are bound together as a base pair, while A and T are bound together as another base pair. This complementary base pairing structure means that both DNA strands are complementary to each other. In this case, since the sequence of one strand is "TCGAACTCA", the complementary DNA strand would have the sequence "AGCTTGAGT".
By genetic modification and evolutionary processes, biodiversity is increased and decreased by habitat loss, population reduction and extinction. The number and relative abundance of species present in a given biological organization is simply species diversity (population, ecosystem, Earth).
Answer:
Genetic Modification is a procedure to change the qualities of a plant, creature or miniature life form by moving a bit of DNA from one living being to an alternate living being. This is done through focused expulsion of the ideal qualities from the DNA of one living being and adding them to the next living being. This strategy has for instance been utilized to create growths and microorganisms that produce drugs.
Evolution is the cycle by which current creatures have dropped from old progenitors. Evolution is liable for both the surprising similitude we see over all life and the astonishing variety of that life.
Explanation:
Evolution is change in the heritable qualities of organic populaces over progressive ages. These attributes are the statements of qualities that are given from parent to posterity during generation. Various attributes will in general exist inside some random populace because of transformation, hereditary recombination and different wellsprings of hereditary variety. Evolution happens when transformative cycles, for example, regular choice (counting sexual choice) and hereditary float follow up on this variety, bringing about specific qualities getting more normal or uncommon inside a populace.
It is this cycle of development that has offered ascend to biodiversity at each degree of natural association, including the degrees of species, singular life forms and atoms.
what's the function of adrenaline in our body
well
my account got deleted rosa
Answer:
What is the function of adrenaline?
Adrenaline triggers the body's fight-or-flight response. This reaction causes air passages to dilate to provide the muscles with the oxygen they need to either fight danger or flee. Adrenaline also triggers the blood vessels to contract to re-direct blood toward major muscle groups, including the heart and lungs. The body's ability to feel pain also decreases as a result of adrenaline, which is why you can continue running from or fighting danger even when injured. Adrenaline causes a noticeable increase in strength and performance, as well as heightened awareness, in stressful times. After the stress has subsided, adrenaline’s effect can last for up to an hour.
Explanation:
I think I helped
Answer:
Key actions of adrenaline include increasing the heart rate, increasing blood pressure, expanding the air passages of the lungs, enlarging the pupil in the eye (see photo), redistributing blood to the muscles and altering the body's metabolism, so as to maximise blood glucose levels (primarily for the brain).

HELP ASAP PLEASE!! DUE IN 10 MINUTES !!! based on these results which statement correctly predicts what will happen to red blood cells when they are placed in a beaker containing a water solution in which the salt concentration is much higher than the salt concentration in the red blood cells
A:the red blood cells will absorb water and increase in size
B:the red blood cells will lose water and decrease in size
C:red blood cells will of first absorb water than lose water and maintain their normal size
D:the red blood cells will first lose water then absorb water and finally double in size
Answer:
The correct answer is - option B. the red blood cells will lose water and decrease in size.
Explanation:
The movement of the water takes place always from the high concentration region of solute to the low concentration of solute through a semi-permeable membrane. In this case, the representation is showing that placing the cell inside a solution with low concentration solute than the cell makes the cell increase the size, and placing it in a solution high concentration of solute makes it decrease in size due to the transfer of water from more water to the low water area.
Now placing the RBC in a solution with more salt concentration than the cell makes the solution hypertonic which means the solution has more solute concentration and less water so the water move from cell to the solution and cell will shrink and decrease in size.
