Answer:Evaporation of ocean water and the formation of sea ice both increase the salinity of the ocean. However these "salinity raising" factors are continually counterbalanced by processes that decrease salinity such as the continuous input of freshwater from rivers, precipitation of rain and snow, and melting of ice.

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.

To measure a population’s baseline genetic state, it must have _____________ to be in Hardy-Weinberg equilibrium.
A) Gene Flow
B) Random Mating
C) Selection
D) Mutations
Answer:
Random mating
hope it helps!
There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection. If the assumptions are not met for a gene, the population may evolve for that gene (the gene's allele frequencies may change).
To measure a population’s baseline genetic state, it must have random mating to be in Hardy-Weinberg equilibrium (Option B).
The Hardy-Weinberg principle state that the genetic variation in a population will remain constant across generations in the absence of different evolutionary forces.The Hardy-Weinberg assumptions include random mating, no mutation, no gene flow, infinite population size, and absence of selection.In consequence, random mating acts to prevent any change in the allele frequencies.In conclusion, to measure a population’s baseline genetic state, it must have random mating to be in Hardy-Weinberg equilibrium (Option B).

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.

B. Species X evolved later than Species U but before Species s.
С.
Species T is the ancestor of Species S.
D
Species U and V evolved from Species S.
Answer:
4
Explanation:
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.

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.

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.
