What evidence suggests that epigenetic effects may cause these phenotypic differences in monozygotic twins
Answer:
Epigenetic marks (e.g., DNA methylation patterns) in older twins are more pronounced than in younger twins
Explanation:
Epigenetics refers to any heritable phenotypic change that does not involve alterations in the DNA sequence but impacts gene expression. Epigenetic modifications can be classified into three types: DNA methylation, histone modifications (i.e., acetylation, methylation, phosphorylation, etc) and regulatory non-coding RNA (ncRNAs) pathways. Epigenetic modifications in (epi)genome enable to explain how two individuals with identical genetic material (such as monozygotic twins) can have different phenotypes. In older twins, epigenetic differentiation will be higher than in younger ones due to the divergence between epigenomes as a result of age.
When a cold air mass replaces a warm air mass, it's called an)
front.
A. Stationary
B. Warm
C. Occluded
D. Cold
When a cold air mass replaces a warm air mass, it's called a Cold front (Option D).
What is a Cold front?A cold front is a limit between two masses of air (one mass that is cool and the other that is warm).
This cold front may be very unstable and thus may be associated with the presence of storms.
In mid-higher latitudes, cold fronts generally advance the Equator by pushing the warm air up.
In conclusion, when a cold air mass replaces a warm air mass, it's called a Cold front (Option D).

Deoxyribonucleotides, which are DNA precursors, are derived from ribonucleotides. Ribonucleotide reductase catalyzes the conversion. Answer the five questions about ribonucleotide reductase.
The given question incomplete. However, the missing part is given below:
1.Which of the following are substrates of the ribonucleotide reductase reaction? 2.Which of the following are products of the ribonucleotide reductase reaction? 3.What is the best description of the reaction? 4. what is the ultimate electron donor? 5.Which of the following can directly donate an electron to ribonucleotide reductase?
Answer:
The correct answer is-
1. NDP (ADP, CDP, GDP, or TDP)
2. dNDP ( dADP. dCDP, dGDP, or dTDP)
3. Oxidation-reduction
4. NADPH
5. Thioredoxin
Explanation:
Ribonucleotide reductase reaction is catalyzed by the enzyme called ribonucleotide reductase which is a key enzyme that synthesizeS the deoxyribonucleotide from ribonucleotide, Deoxyribonucleotide is the precursor of DNA.
This reaction is an oxidation-reduction reaction that reduces all ribonucleotides ADP, CDP, GDP, or TDP to dADP. dCDP, dGDP, or dTDP. The ultimate electron donor in this oxidative-reductive reaction is NADPH however thioredoxin directly transfers an electron to ribonucleotide.

Which of the following identifies the process shown at point Z?
Answer: Translation
Explanation: Transcription is converting DNA to mRNA. They're both made of nucleotides, so you're just transcribing the information from one form to the other. Translation is turning mRNA to protein, so you're translating the information from one language to another.
According to the diagram, it identified the process shown at point Z should be considered as the Translation.
What is Translation?In terms of molecular biology and genetics, translation refer to the process where ribosomes in the cytoplasm should synthesize the proteins after considering the process of transcription of DNA to RNA with respect to the cell's nucleus.

Energy from______ and other nutrients is transferred to _______ through a series of chemical reactions?
Energy from carbohydrates and other nutrients is transferred to ATP through a series of chemical reactions
What is the transfer of energy?The transfer of energy is the transfer of energy from one organism to another organism. This transfer of energy and nutrient from one organism to another is called a food chain.
The food chain shows the transfers of energy, and these animals are divided into different levels of nutrients and energy. These levels are atrophy, heterotrophs, and decomposers.
The autotrophs have the largest amount of energy and heterotrophs have a lower form of energy, as autotrophs contain energy, and heterotrophs take energy from heterotrophs.
Thus, Chemical processes convert energy from nutrients such as carbs and other foods into ATP.

D Improve water quality standards for industries located on lakes and rivers.
Answer: Improve water quality standards for industries located on lakes and rivers
Explanation:
A way of protecting water for human consumption is to: D Improve water quality standards for industries located on lakes and rivers.
Water can be defined as a liquid molecule that comprises two (2) main chemical elements; hydrogen and oxygen in the ratio of two to one (2:1).
Generally, water is considered to be an important and essential chemical molecule because it aids in the growth and development of the body of living organisms.
Furthermore, lakes and rivers serves as the primary source of water for consumption use by humans after a proper treatment process.
Hence, it is very important that some effective and efficient waste management systems or procedures are put in place by industries that are situated (located) around lakes and rivers, so as to mitigate or prevent water pollution.
In conclusion, one of the best ways to prevent water pollution and protect water for human consumption is to improve water quality standards for industries located on lakes and rivers.

Individuals with a genetic defect in phenylalanine hydroxylase require an additional amino acid in their diet which is not an essential amino acid in the ordinary human diet. Which nonessential amino acid has become essential because of the lack of phenylalanine hydroxylase
Answer:
Tyrosine.
Explanation:
Tyrosine is a non-essential amino acid, it is part of proteins and is considered an aromatic amino acid. Its synthesis occurs from the hydroxylation of phenylalanine as long as it contains an adequate supply of this amino acid.Phenylketonuria is a hereditary disease whose main treatment is dietary restriction of the amino acid phenylalanine. People with phenylketonuria may have low levels of the amino acid tyrosine in their blood.Phenylalanine hydroxylase is an enzyme that converts phenylalanine to tyrosine. Deficiency of the enzyme phenylalanine hydroxylase is a congenital error of metabolism.
