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.

Arteries carry oxygenated blood away from the heart and typically have ________________ blood pressure. Veins carry deoxygenated
KatRina [158]
The correct answer is high, low.

Arteries are part of the circulatory system and are responsible for carrying blood away from the heart and around the body. The arterial blood is oxygenated and this process ensures that every tissue around the body will receive oxygen and nutrients through this blood flow.

Veins are also part of the circulatory system and are responsible for carrying the deoxygenated blood from the tissues back to the heart.

Venous pressure is much lower than the arterial pressure. More specifically, venous pressure ranges from 5 to 8 mmHg, while arterial pressure ranges from 15 to 30 mmHg.

Echinoderms _____. _____ Select one: a. have an exoskeleton of hard calcareous plates b. often use tube feet to move around in t
atroni [7]

Answer:

B. often use tube feet to move around in their environment

Explanation:

Tube feet are tiny tubular projections of echinoderms on the underside (oral side). They are a member of the echinoderm water vascular system.

Tubular feet are used for feeding, breathing and shifting. They are arranged around the sides, in grooves. They work by hydraulic pressure. They are used to transfer food in the centre to the oral mouth, and may stick to surfaces. Tube feet allow certain animals to stick and travel slowly to the ocean floor. for example starfish uses tube feet for the above functions.

Hence, the correct option is B.

Which situation would not encourage competition?
torisob [31]

A long, wet season results in additional earthworms in a robin habitat.

Explanation:

A long, wet season resulting in additional earthworms in a robin habitat will not lead to competition in an ecosystem or area.

Competition between organisms is the struggle for limited resources in the environment that are beneficial to all lives.

  • Competition is usually driven by shortages and lack of resources to make life better in the ecosystem.
  • When resources becomes depleted and are in limited amount organisms will begin to strive among on another to develop advantages that would make them top out.
  • A long, wet season resulting in the introduction of additional earthworms in a robin habitat is not an example of competition.
  • The earthworms available is a limiting factor and this has been circumvented by the introduction of more earthworms during the prolonged wet season.

In ________and ________ no energy is used. Which one needs a helper to get things across?__________
MissTica
In DIFFUSION AND FACILITATED DIFFUSION no energy is used. The one that needs a helper to get thing across is FACILITATED DIFFUSION.<span> Facilitated diffusion involves the diffusion of materials across the cell plasma membrane with the aid of membrane proteins such as carriers and channels. The process of diffusion does not need a carrier, the molecules to be transported just move on their own from the area of high concentration to the region of low concentration until the concentration in the space become uniform.</span>
