Answer:
Homeostasis is the tendency to resist change in order to maintain a stable, relatively constant internal environment. Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points.
Suppose there was NO meiotic recombination but maternal and paternal chromsomes still assorted randomly during meiosis. How many different kids would be possible from two parents?
Answer:
8,324,608 chromosome combinations
Explanation:
During meiosis, chromosomes separate independently so that only one chromosome came from the father and the other homologous chromosome came from the mother. This process of independent assortment produces a huge amount of possible combinations in the diploid zygote cell. In humans, the haploid number of chromosomes is n = 23, thereby there are 2²³ = 8,324,608 chromosome combinations. Thus, the independent assortment of chromosomes during meiosis is a key factor that contributes to genetic variation in the offspring.
In a direct variation, y=39 when x=3. Find the value of y when x=2.

What amazing thing can plants do with carbon dioxide and water molecules? How?
Answer:
In the process of photosynthesis the plants make their own food by using carbon dioxide, water, sunlight and soil.
The energy from sun light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen.

Choose the best explanation of a partial solar eclipse?
A. The earth only partially covers the sun during the eclipse
B. The moons phase is full and blocks out most but not all of the sun
C. During a new moon phase there is usually a partial but not total eclipse
D. The moon only partially covers the sun during the eclipse
Answer:
The best explanation for a partial solar eclipse is that moon only partially covers the sun during the eclipse (option D).
Explanation:
A solar eclipse occurs when the moon stands between the sun and the earth, which happens when the moon is near the plane of the ecliptic, that is, the point where the orbits of the earth and the sun intersect.
A partial solar eclipse occurs when the moon partially covers the sun, which depends on the observer's point of view on the earth and his geographical location.
The other options are not correct because:
A. If the earth stands between the sun and the moon, lunar eclipses occur.
B and C. During a solar eclipse it is not possible to see lunar phases, which occur when the sun's rays are reflected off the satellite.

Compare and contrast serine proteases and aspartic proteases. Not all answers will be used. Serine protease Both Aspartic protease
Answer: The main similarity between the serine protease and aspartic protease is that these enzymes catalyze the break down or hydrolysis of the peptide bonds.
Explanation:
Serine protease structure has a triad of histidine, serine, and aspartic acid that are joined with the hydrogen bonds. Aspartic protease has a structure which includes the two aspartic acid residues which attack the peptide bond.
Serine protease catalyzes the hydrolysis of the peptide bonds with the the help of two tetrahedral intermediates, whereas the aspartic protease abstracts the proton from water molecule it results in nucleophilic attack on the carbonyl atom of carbon resulting in breakage of peptide bond.

1.what are three factors that affect the rate of chemical reactions?
2.select one of these factors and describe how it affects chemical reactions within our bodies.
Explanation:
The factors that affects the rate of chemical reactions are;
Nature of reactants Concentration of reactants or pressureTemperature Presence of catalystSunlightIn our body, the nature of reactants is very important. A food substance in solid form undergoes slow digestive process because it has little surface area exposure for the action of digestive chemicals. Most solid food are usually chewed in the mouth before digesting them to increase their surface area.
The increasing order of food digestion is;
lumps to granules to powder and to liquids.

If a woman is heterozygous for widow's peak
(widow's peak is dominant over a smooth hairline) has children with a man with a smooth hairline, what
are the possible phenotypes of their children?
It is impossible to determine the possible phenotypes.
O All of their children will have a widow's peak.
O None of their children will have a widow's peak.
It is possible for their children to either have widow's peak or a smooth hairline.
Answer:
It is possible for their children to either have widow's peak or a smooth hairline.
Explanation:
Let's say that the widow's peak allele is W (dominant) and the smooth hairline is w (recessive).
A woman heterozygous for widow's peak is Ww. A man with a smooth hairline must have two copies of the smooth allele since it is a recessive trait, so he must be ww.
The cross is Ww x ww
W w
w Ww ww
w Ww ww
There is a 50% chance that the children will have the genotype Ww, and therefore have a widow's peak. There is a 50% chance the children will be ww, and will therefore have a smooth hairline.
So, It is possible for their children to either have widow's peak or a smooth hairline.

By imagining where she was when she last walked in the door, Marla retraced her steps to find her keys. This is an
example of a
dependent memory.
A. mood
B. echoic
c. state of being
D. context
Marla imagining where she was and retracing her steps to find her keys is an
example of a context dependent memory.
Context-dependent memory can defined as when an individual recalls
specific events or information when the context present are the same for
that of the encoding and retrieval of the event.
In this scenario, Maria imagining where she was when she last walked in the
door is the same as where her key is to be found.

The mechanoreceptors sensing light touch are concentrated on
A. the back of the body.
B. hairy skin like forearms and legs.
C. hairless skin like lips and fingertips.
D. the scalp.
Answer:
Hairless skin areas
Explanation:
The mechanoreceptors sensing light touch are concentrated on Hairless skin like lips and fingertips, option C is correct.
Mechanoreceptors sensing light touch are most concentrated on hairless skin regions such as lips and fingertips. These areas have a higher density of specialized touch receptors, known as Meissner's corpuscles and Merkel cells, which are particularly sensitive to light touch sensations. Hairless skin allows for more direct contact with external stimuli, enhancing the perception of gentle touch and fine tactile discrimination.
In contrast, areas with hair, like the back of the body or the scalp, have a lower density of these mechanoreceptors and are more involved in detecting other sensory modalities such as temperature or pain, option C is correct.
