B. an acid increases the concentration of H+ ions. A base is a substance that releases hydroxide (OH-) ions (in aqueous solution, donates electrons and accepts protons)
Explanation:
A fever is an abnormal elevation of the body temperature. A low to moderate fever, when a low to moderate fever, when allowed to run its course, can be beneficial. fever can promote interferon activity. Fever can also accelerate tissue repair. lastly, fever will inhibit the reproduction of bacteria and viruses.
It is important to note that fever is not an illness, however, it is a symptom, or sign that your body is fighting an illness or infection. Fever stimulates the body's defenses, sending white blood cells and other "fighter" cells to fight and destroy the cause of the infection.
Answer:
So that in a guinea pig cross in the offspring the recessive trait —long hair— can be observed in 25%, the most probable genotype of the parents is heterozygous Ss.
Explanation:
In guinea pigs, for the characteristic<u> hair length, short hair is the dominant allele and long hair is the recessive one</u>.
In order for 25% of the offspring to express the recessive characteristic, the parents must have a recessive genotype, which can be seen in Punnett's Square:
P: <u>Ss X Ss
</u>
<em>Alleles S s
</em>
<em>S SS Ss
</em>
<em>s Ss ss
</em>
Where the offspring is:
- <em>50% Ss with short hair phenotype
</em>
- <em>25% SS with short hair phenotype
</em>
- <em>25% ss whose phenotype would be long hair.
</em>
According to this, heterozygous parents for the characteristic long hair in guinea pigs have a 25% chance of having offspring with long hair.

Answer:
Enzymes speed up the chemical reactions in living cells.
Explanation:
An enzyme is a biological catalyst and is almost always a protein. It speeds up the rate of a specific chemical reaction in the cell. The enzyme is not destroyed during the reaction and is used over and over.
