Answer:

B) astrocytes

Explanation:

Cells other than neurons that play an important role in the normal functioning of nervous system are called Neuroglia or glial cells.

Satellite cells, astrocytes, schwann cells and oligodendrocytes are all examples of glial cells.

⇒Satellite cells provide protection and nutrition to cells in peripheral nervous system ( peripheral nerves and ganglia).

⇒<em><u>Astrocytes</u></em> play an important role in central nervous system (brain and spinal cord). They provide protection to neurons, scavenge ions, form the blood-brain barrier and also maintain extracellular environment suitable for neuronal functioning.

⇒Schwann cells are found in the peripheral nervous system and myelinate the axons of neurons.

⇒Oligodendrocytes are found in central nervous system and produce myelin sheath which myelinates (insulates) axons  of neurons. Their function is similar to schwann cells but in the central nervous system.

From the above discussion it is clear that the answer is B) Astrocytes as these maintain a suitable chemical environment for the neurons.

Explain why some of the trees in the plantation are dying​
GrogVix [38]

Explanation:

What would cause a tree to die?

There are 5 factors to which a tree eventually succumbs: death from its environment, death from harmful insects and diseases, death from a catastrophic event, death from age-related collapse (starvation) and of course, death from harvest.

Describes what happens as carbon cycles through the environment. What takes carbon out of the environment? What things put carbo
Citrus2011 [14]

Answer:

Carbon moves through Earth's ecosystems in a cycle referred to as the It is through carbon dioxide gas found in Earth's atmosphere that carbon enters the living parts of an ecosystem. ... To release the energy in food, organisms break down the carbon compounds—a process called respiration.

Photosynthesis removes carbon dioxide naturally—and trees are especially good at storing carbon removed from the atmosphere by photosynthesis. Expanding forests, restoring existing forests and managing forests to encourage more carbon uptake can leverage the power of photosynthesis to convert carbon dioxide in the air into carbon stored in wood and soils. The decompsition of the soil helps create a natural environment which keeps the trees healthy and continuously producing photosynthesis. Direct air capture is the process of chemically scrubbing combustionable carbon dioxide directly from the ambient air, and then storing it either underground or in long-lived products. This new technology is not unlike the carbon capture and storage technology for various emissions sources like power plants and industrial facilities. The difference is that direct air capture removes carbon from the atmosphere instead of consuming emissions.

Carbon dioxide is added to the atmosphere by human activities. When hydrocarbon fuels (i.e. wood, coal, natural gas, gasoline, and oil) are burned, carbon dioxide is released. During combustion or burning, carbon from fossil fuels combine with oxygen in the air to form carbon dioxide. Animals and plants need to get rid of carbon dioxide gas through a process called respiration.

Greenhouse gases have far-ranging environmental and health effects. They cause climate change by trapping heat, and they also contribute to respiratory disease from smog and air pollution. Extreme weather, food supply disruptions, and increased wildfires are other effects of climate change caused by greenhouse gases.If not for the greenhouse effect, Earth would be an ice ball. So, CO2 and other greenhouse gases are good—up to a point. But CO2 is so good at holding in heat from the Sun, that even a small increase in CO2 in the atmosphere can cause Earth to get even warmer.

Hope this helps :)

Prokaryote's ability to regulate patterns of gene expression most likely promotes the organism's survival by ________.a) allowin
Olin [163]

Answer:

c) allowing an organism to adjust to changes in environmental conditions

Explanation:

A stimulus can be defined as any change in the external or internal environment that produces a corresponding response in the organism. These responses enable the organism to maintain an internal equilibrium (homeostasis). Gene expression in prokaryotes, which are the simplest forms of life, is highly regulated by environmental stimuli. Some examples of stimuli known to regulate gene expression patterns in prokaryotic organisms are light, water, pressure, temperature, etc.
