Why does the control of blood sugar by insulin show negative feedback?
Select one:
The release of insulin causes sugar levels to increase even more.
Sugar lowers the levels of insulin back to the normal levels.
The release of insulin brings the sugar levels back to normal.
Insulin mixes with the sugar to prevent it from damaging the cells.
Answer:
The control of blood sugar (glucose) by insulin is a good example of a negative feedback mechanism. When blood sugar rises, receptors in the body sense a change. In turn, the control center (pancreas) secretes insulin into the blood effectively lowering blood sugar levels.

explain how the hydrosphere and atmosphere are related.
Answer:
Water circulates in a cycle across the hydrosphere. Clouds gather water, which then falls to Earth as rain or snow. Rivers, lakes, and seas store this water. Then it evaporates back into the atmosphere, restarting the loop.
Explanation:
Answer:
The hydrosphere is the part of Earth were all the water is contained.
The atmosphere is the part of Earth were all the gases are contained.
These two are related because the hydrosphere is inside the atmosphere.
The hydrosphere goes down below sea level, because of several trenches and other holes like the Mariana trench. The hydrosphere also goes around 20 kilometres in the air because of clouds.

Decay adds carbon to the atmosphere.
Two radioactive nuclei A and B are present in equal numbers to begin with. Three days later, there are 2.44 times as many A nuclei as there are B nuclei. The half-life of species B is 1.14 days. Find the half-life of species A (in days).
Answer:
2.23 days
Explanation:
Given that;
N=Noe^-kt
Where;
N= number of radioactive nuclei present at time =t
No= number of radioactive nuclei originally present
k = decay constant
t = time taken
But k = ln2/T
Where T is the half life of the radioactive nuclei
Hence;
NA= Noe^-ln2t/TA (1)
NB= Noe^-ln2t/TB (2)
But NA =2.44NB
2.44NB = Noe^-ln2t/TA (3)
NB= Noe^-ln2t/TB (4)
Divide (3) by (4)
2.44NB/NB = Noe^-ln2t/TA/Noe^-ln2t/TB
2.44 = e^-ln2t/TA + ln2t/TB
Taking natural logarithm of both sides
ln2.44 = -ln2t/TA + ln2t/TB
Given that TB = 1.14 days
TA= -ln2t(ln2.44 -ln2t/TB )^-1
TA= -(2.079) (0.892 - 2.079/1.14)^-1
TA = 2.23 days

The periodic shedding of the uterine lining usually takes place --
O after menopause
O during pregnancy
O if fertilization does not occur
O before puberty begins
Answer:
before puberty begins
Explanation:
because on your menstrual cycle the blood clots are actually pieces of uterus and that's actually your uterine shedding and it usually starts doing that even before your period begins so it definitely be before puberty begins hope I didn't make the answer to awkward but that's the truth LOL
The periodic shedding of the uterine lining usually takes place before puberty begins. The correct option is D.
Thus, An egg is released from the ovary into the fallopian tube during ovulation, which happens roughly halfway through a woman's menstrual cycle. The uterine lining that was developed to support a potential pregnancy is no longer required if fertilization of the egg by a sperm does not take place.
The uterine lining sheds as a result, causing menstruation, often known as the monthly menstrual cycle. In a typical 28-day menstrual cycle, this shedding typically takes place around 14 days following ovulation.
In females of reproductive age, menstruation is a normal process that lasts until menopause, at which point it ceases. Menstruation is a component of the menstrual cycle.
Thus, The periodic shedding of the uterine lining usually takes place before puberty begins. The correct option is D.

The paternity test is done to test the real father of the child by comparing the child's DNA with the parents' DNA. It gives the result based on the DNA analysis, and here the test is shown in the gel electrophoresis. Gel electrophoresis shows the DNA segments of the child, mother, and three men, but the child DNA segments match the DNA segment of the dad 3. The child's DNA segments match with the mother, and the rest match with Dad 3, confirming that Dad 3 is the child's biological father.

this is science, please put a short desrciption for each of the sun's layers.
Answer: The core is the only place where nuclear fusion reactions can happen. In this broad zone, heat from the core cools dramatically, from between seven million K to two million K. Convection continues to be efficient in transporting heat until layers are reached where the density is so low that radiation from the hot up-flowing gas can escape directly into space. The lowest layer of the sun's atmosphere is the photosphere. It is about 300 miles (500 kilometers) thick. This layer is where the sun's energy is released as light. At other times, light from the chromosphere is usually too weak to be seen against the brighter photosphere. The chromosphere may play a role in conducting heat from the interior of the sun to its outermost layer, the corona. The corona is the outer atmosphere of the Sun. It extends many thousands of kilometers (miles) above the visible "surface" of the Sun, gradually transforming into the solar wind that flows outward through our solar system.

treat a patient suspected of going into shock?
Check all that apply.
Cover the patient with a blanket.
Provide food and water to the patient.
Have the patient get up and walk around.
Monitor heart rate and breathing every five
minutes
Answer:
The answer is the last one, "Monitor heart rate and breathing every five minutes".
Explanation:
Because it can determine when the patient will be going into shock.
The steps that should be taken to treat a patient suspected of going into shock are: Cover the patient with a blanket and monitor heart rate and breathing every five minutes.
Covering the patient with a blanket helps maintain their body temperature, as shock can lead to a drop in body temperature due to poor blood circulation and reduced oxygen supply to tissues. This simple measure can help prevent hypothermia and provide comfort to the patient during emergency care. Monitoring the patient's heart rate and breathing every five minutes is essential to assess their condition and detect any signs of deterioration.
Shock can lead to rapid and weak pulse, as well as shallow and irregular breathing. Regularly monitoring these vital signs allows medical professionals to identify early signs of worsening shock or other critical changes in the patient's condition. Prompt recognition of these changes can lead to timely intervention and improved outcomes for the patient.

Normally, the clown fish readily swims among the tentacles of the sea anemones; the parrot fish avoids them. One hypothesis for the clown fish's apparent immunity is that they slowly build a tolerance to the sea anemone's toxin. A second hypothesis is that a chemical in the mucus that coats the clown fish prevents the nematocysts from being triggered.
Required:
Draw the graphs that supports the first, but not the second, of these hypotheses.
Answer:
The correct answer is - parrot fish - high, Clown fish - high.
Explanation:
According to the first hypothesis, the clown fish developed the immunity to the sea anemone's toxin so there would be a higher number of clown fish that swims among the tentacles of the sea anemones. The parrot fish avoids them also leads to a higher number of these fishes.
The correct graph that supports the first hypothesis that says that the clown fish's developed immunity build by them slowly, a tolerance to the sea anemone's toxin from tentacles of sea anemones.

In cattle, black coat color is dominant to white coat color. A farmer has a black male of undetermined genotype. How can the farmer determine the genotype of the black male?
Answer:
by looking at the offspring's phenotype
By observing phenotype of a cattle, the farmer can determine its genotype.
What do you mean by phenotype?Phenotype is an observable characteristics.Example: hair color, eye color, etc.It depends upon the genotype composition.What do you mean by genotype?"Genotype refers to the genetic makeup of an organism."It is given that black coat color is dominant and dominant allele for black color is denoted by B and recessive one is denoted by b.
So, in order to have black color the possible genotype would be Bb or BB.
If the offspring of the cattle have black color too, the genotype will be BB.
And if the offspring of the cattle have both black color as well as non-black color, the genotype will be Bb.
Hence, the farmer can determine the genotype of the black male by its phenotype.
