Hello. Your question is incomplete. The complete question asks for the correct answer to be found based on Catalase is an essential enzyme in living beings since all cells need it.
Answer:
B. Cells only function within a specific temperature range because enzymes only function within a specific temperature range.
Explanation:
Catalase needs to be present in all cells of the living organism because it is responsible for the decomposition of hydrogen peroxide that cannot stay inside cells for long periods of time. Following this type of reasoning, we can say that it is necessary to maintain a constant temperature for the enzymes of an organism to function well because all enzymes have a specific temperature range, even catalase.
The specific temperature range determines that the enzymes will only work within that range. Therefore, an environment where the temperature is below or above that specific range, can prevent the enzyme from functioning and even cause irreversible damage to the enzyme.

Changes in _____ result in the formation of metamorphic rocks.
a. Weathering
b. Sedimentation
c. BothAandB
d. Temperature and Pressure
Answer:
During metamorphism the mineral content and texture of the protolith are changed due to changes in the physical and chemical environment of the rock. Metamorphism can be caused by burial, tectonic stress, heating by magma, or alteration by fluids.

Your friend Joe has a younger brother Sam and two older sisters. Sam has a strange disorder that has caused his hair to turn green. The doctor says that this is caused by a single gene that is inherited, and that boys are more likely to have green hair then girls. However Joe, his sisters, and both of his parents have normal hair color. Joe does not know much biology and is confused. Explain to Joe how his brother's condition could have arisen even though Joe has normal hair. Then discuss the likelihood that a) Joe, and b) Sam will have children with green hair. Assume that they both marry women with normal hair color. You will need to include information on meiosis and transmission of genes to assure that Joe understands. HINT: As part of your answer, indicate the percent of girls vs. boys that you predict would have green hair if fathered by Joe vs. Sam.
Answer:
The correct answer is - it is due to the case of sex-linked recessive disorder.
Explanation:
It is pointed out by the doctor that Sam has a condition due to recessive allele and it is given that boys have this condition more than girls which suggests that it is a sex-linked recessive disorder. This comes from their parents but it is given that the father has normal hair which means the father has no recessive allele, then it must come from the mother even mother has not this condition but she could be a carrier for this trait.
Joe and his sister do not have this condition as they get the normal dominant allele from mother and father.
The chances of being a carrier by his sisters are 50%. If Joe marries
IF Joe marries a non-carrier woman, he will have all normal children with no green hair. IF Joe marries a normal hair color carrier women then there would 25% chances of being diseased offspring and 50% chances of being a carrier, and if women is completely normal then all offspring will be normal.
carrier woman, his children will have a 25% chance of being green-haired. A 25% chance of being
IF Sam marries a normal woman, the children will have a 25% chance of being a carrier, a 25% chance of being green-haired, and a 50% chance of being normal.

substance in which the monomer is a nucleotide _______
A - Carbohydrates
B - Nucleic Acids
C - Proteins
D - Fats
Nucleic acid is a substance in which the monomer is a nucleotide. Therefore, option B is correct.
What are nucleic acids?Biopolymers and macromolecules called nucleic acids are important for all known forms of life. They are constructed of monomers called nucleotides, which are composed of a nitrogenous base (adenine, guanine, thymine, uracil, and cytosine), a phosphate group, and a 5-carbon sugar.
The components that make up an individual's genetic code are nucleic acids. Deoxyribonucleic acid (DNA) and ribonucleic acid are the principal two examples of nucleic acids (RNA). They have an important role in heredity and protein synthesis.
Thus, A nucleotide serves as the monomer of a material known as nucleic acid. Therefore, option B is correct.

describe two ways to transfer electric charge
.Answer: conduction or polarization
Answer:
conduction, friction
Explanation:
Friciton: When insulating materials rub against each other, they may become electrically charged . Electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. The material that gains electrons becomes negatively charged.
Conduction: During charging by conduction, both objects acquire the same type of charge. If a negative object is used to charge a neutral object, then both objects become charged negatively. In order for the neutral sphere to become negative, it must gain electrons from the negatively charged rod.

A population of mosquitoes is exposed to the pesticide DDT for several generations. At the end of that time, most individuals in the population are resistant to DDT. The most likely reason is that:
A. random mutations in each generation made mosquitoes resistant to DDT.
B. some individuals in the original population had the mutations that led to resistance.
C. DDT caused the mutations that led to resistance.
D. somatic mutations in the original population were passed on to subsequent generations.
E. by chance, new mutations that led to DDT resistance arose after DDT was used.
Answer:
B
Explanation:
A population of mosquitoes is exposed to the pesticide DDT for several generations. At the end of that time, most individuals in the population are resistant to DDT and the most likely reason is that some individuals in the original population had the mutations that led to resistance. Option B is correct.
What is mutation ?Mutation is the change in which there is slight change in the genome sequence of a DNA or RNA along with the gene. The mutation lead to various types to adaptations along with the diseases.
Resistance is the condition when the species on the multiple exposures develop certain kind of adaptations to it and these traits are sometime inherited sometimes not inherited.
Mutations are friendly as well where sometimes a disease causing mutation can be altered with the further mutation in it.
Therefore on the multiple exposure it led to condition of resistance in the species.

The statement that is best supported by the image is that species T and species U are related to species X.
What is evolution?Is the gradual development of new forms of organisms from their ancestral forms.
In the image, X is the ancestor of T, U, V, and S. Thus T, U, V, and S are related by common ancestry.
Thus, it is correct to say that T and U are related to species X.
However, it is incorrect to say that X evolved later or species U and V evolved from S.
