Yes, it is. The chart shows that the initial charge of the neuron is negative. When the neuron is stimulated, sodium ions enter the cell. So, the voltage inside the cell changes to positive. When potassium ions move outward, the voltage decreases until it reaches its previous state.

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.

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.

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.

Answer:

Water initially moves into the root hair cells by osmosis, because the mineral content of the cells is higher than that of the surrounding environment. Thus, a root pressure is established and extends into the microscopic tubes of the xylem.

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.

Genetic variation is increased by meiosis

Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase.

Answer: to contract to cause movement in the body

Explanation:

AP*X

The main function of nervous tissue C. contract causes movement in the body.

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.

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.

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.

Answer:

Eblow is a terrible thing.

Explanation:

Answer:

I think its, option b) Viruses are not living organisms, but bacteria are living.

Explanation:

The other options don't fit "summarize the differences b/w bacteria and virus", or simply don't make sense...  

Bacteria can replicate as well, not only virus, so that cannot be a difference

The virus is often the one being more dangerous, there is something called "good bacteria"

A virus isn't  living, (for the sake of this answer), and we all know for sure that bacteria is living

So, that's how option b is correct
