How can the role of epigenetics in cancer be reconciled with the idea that cancer is caused by the accumulation of genetic mutations in tumor-suppressor genes and proto-oncogenes

Answers

Answer:

Epigenetic mechanisms control the activity of genes involved in DNA repair pathways and cell growth

Explanation:

Epigenetics can be defined as the study of the alterations in gene expression patterns that do not involve alterations in the DNA sequence. Epigenetic mechanisms include 1-DNA methylation, 2-histone modifications (i.e., methylation, acetylation, phosphorylation, ubiquitination, etc.) and 3-non-coding RNA pathways (microRNAs, long ncRNAs, etc). These epigenetic mechanisms work together to control gene expression patterns by activating or silencing genes at the level of transcription, in a mode that is dependent on the cell type and developmental stage. In consequence, the failure of the epigenetic mechanisms modifies the activity of genes which may be involved in DNA repair pathways and thereby it may lead to severe disorders including some cancers.

Which division has a single preganglionic neurons with many axon collaterals that forms 20 or more synapses with postganglionic neurons?

a. sympathetic motor division
b. parasympathetic motor division
c. sympathetic sensory division
d. parasympathetic sensory division

Answers

Answer:

i believe its c

Explanation:

A single sympathetic preganglionic fiber has many axon collaterals and may synapse with 20 or more postganglionic neurons.

The postganglionic axons typically terminate in several visceral effectors and therefore the effects of sympathetic stimulation are more widespread than the effects of parasympathetic stimulation.

How do plants contribute to the water cycle?

Answers

Answer:

Plants absorb water from the soil. The water moves from the roots through the stems to the leaves. Once water reaches the leaves, some of it evaporates from the leaves, adding to the amount of water vapor in the air. This process of evaporation through plant leaves is called transpiration.

I really hope this helps!

Plants contribute to the water cycle in several ways through Transpiration, evaporation, Precipitation: and infiltration.

How do we explain?

Plants take in water through their roots and transport it up to their leaves. As water evaporates from the leaves, it creates a force that pulls more water up from the roots through a process called transpiration, and it is a major way that water moves through the atmosphere.

Water from plants and soil also evaporates into the atmosphere. This process is called evaporation, and it is another important way that water moves through the water cycle.

When water vapor in the atmosphere cools, it condenses and falls back to Earth as precipitation. This can be in the form of rain, snow, sleet, or hail.

The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body's electrical wiring. Structurally, the nervous system has two components: the central nervous system and the peripheral nervous system.

Conclusion: The nervous system is a highly integrated system. The nervous system has three overlapping functions based on sensory input, integration, and motor output. At a more integrative level, the primary function of the nervous system is to control and communicate information throughout the body.

Which cellular structure in plant cells is most responsible for having less flexible animal cells

Answers

Answer:

The cellulose cell wall in plants

Explanation:

All eukaryotic cells, both plant and animals cells have a cell membrane which is an outer covering of the contents of the cell. Also plants and animals cells have many structures and cell organelles in common such as the mitochondria, the endoplasmic reticulum, ribosomes, golgi bodies, etc. However, plant cells have a more rigid structure than animals cells because of the presence of an extra structure known as the cell wall, covering their cell membranes.

The cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell, providing structural support and protection. The cell wall is composed mainly of cellulose, but contains proteins as well as other polysaccharides too.

Another structure present in plants that serves to maintain the rigidity of the plant cell is the large central vacuole. The main role of the vacuole is to maintain turgor pressure by pushing the plasma membrane against the cell wall due to the pressure of fluids contained within it.

Answers

Yes, personally I believe that solar cells, wind farms, tidal power, hydropower and thermal energy will solve future energy needs. The most common energy right now is coal and by burning fossils fuels, we are risking climate change as well as limiting our resources. Supplies won’t last forever especially at the rate we are going. By using sun, wind, and water as sources of energy, we have renewable energy which won’t run out anytime soon. Those energy are low cost and solves pollution issues!

Supplies won’t last forever especially at the rate we are going. By using sun, wind, and water as sources of energy, we have renewable energy which would not run out anytime as soon as we required. Those energy charges are low cost and solves pollution issues too.

Heat energy has been transferred from one place to another by three main processes and in convection, heat energy has been carried by the movement of particles of matter. In conduction, heat is transferred by particles vibrating. In radiation, heat is carried directly by electromagnetic waves.

Explain in a few sentences how the carbon, nitrogen, and phosphorus overlap. How do these cycles cross paths through earths spheres?

Answers

Answer:

Explanation:Energy flow and nutrient circulation are the major functions of the ecosystem.

Energy is lost as heat forever in terms of the usefulness of the system. On the other hand, nutrients of food matter never get used up. They can be recycled again and again indefinitely.

Carbon, hydrogen, oxygen, nitrogen and phosphorus as elements and compounds makeup 97% of the mass of our bodies and are more than 95% of the mass of all living organisms.

In addition to these, about 15 to 25 other elements are needed in some form for the survival and good health of plants and animals.

These elements or mineral nutrients are always in circulation moving from non-living to living and then back to the non-living components of the ecosystem in a more or less circular fashion.

This circular fashion is known as biogeochemical cycling (bio for living; geo for atmosphere).

Among the most important nutrient cycles are the carbon nutrient cycle and the nitrogen nutrient cycle.

There are many other nutrient cycles that are important in ecology, including a large number of trace mineral nutrient cycles.
