Answer:
Option B. compounds
Explanation:
Compound is a type pure substance which is formed when two or more than two elements combine together chemically in a fixed ratio. It is represented by a chemical formula. Chemically combine means the elements present in the compound make bonds in order to hold each other. So they are not separated by physical methods. It is separated from one another by chemical methods.
The first one is the right answer
Answer:
Potential targets:
1- DNA methyltransferases
2- Chromatin modifiers such as histone acetyltransferases, histone deacetylases, histone methyltransferases, etc.
3- Components of the RNA interference (RNAi) machinery such as Dicer, Argonaute, etc.
Explanation:
Epigenetics can be defined as the study of any heritable change in the phenotype that does not involve modifications in the DNA sequence. Epigenetic mechanisms can be classified into three major types: 1-DNA methylation, 2-histone modifications (e.g., acetylation, methylation, phosphorylation, etc), and 3-regulatory non-coding RNAs (e.g., miRNAs, lncRNAs, siRNAs, etc) that modulate target gene expression via the RNA interference pathway. There are different types of proteins that are involved in these complex epigenetic mechanisms, and those cited above represent only some examples that can be used as therapeutic targets.
Heterotrophs are organisms that must consume food from other organisms because they are unable to synthesize their own food molecules.
<h3>What is heterotrophs?</h3>
- An organism is referred to be a heterotroph if it is unable to manufacture food on its own and must obtain it from other sources of organic carbon, primarily plant or animal materials.
- Heterotrophs are primary, secondary, and tertiary consumers in the food chain but not producers.
- Because they eat producers or other consumers, heterotrophs are referred to as consumers.
- Humans, dogs, and birds are all instances of heterotrophs.
- In a food chain, a group of creatures that supply energy and nutrients to other organisms, heterotrophs occupy the second and third levels.
- An organism is referred to as a heterotroph if it consumes other plants or animals for food and energy.
- Its origins are in the Greek words hetero, which means "other," and trophe, which means "nutrition."
- Autotrophs and heterotrophs are two main classifications of organisms depending on how they receive energy and nutrients.
