Answer:
-provides protection for a cell
-provides a fixed environment inside the cell.
-The cell membrane also provides some structural support for a cell.
Explanation:
1. Burning of fossil fuels.
Under natural conditions the release of carbon from fossil fuels
occurs slowly, as they are sub ducted into the mantle, and CO2 is released
through volcanic activity. However, humans are heavily reliant on fossil fuels,
and extract it from the lithosphere in great quantities. Put in to fire a coal,
oil, natural gas, and other fossil fuels – for industrial movement and power
generation for example, neglect the carbon from the fossil fuels and emits it
as CO2 into the atmosphere.
2.
Land use and land cover change (e.g. deforestation)
Big
part of carbon are stored in living plants. Then, land use changes, most importantly
the clearance of forests (which are very densely inhabited by plants, and
therefore contain a large amount of carbon), can influence the carbon cycle in
two ways. Firstly, removing of vegetation will let the plants die which would
otherwise be capturing carbon from the atmosphere through photosynthesis. And
as dense forests are change by crops/pasture land/built environments, there is
usually a net decrease in the carbon store, as smaller plants (and worse still,
concrete) store far less carbon than large trees. Deforestation also make much
more soil to be eroded, and carbon stored in the soil is rapidly taken into
rivers.
<span>Because the nature is in cycle of the carbon cycle, humans are
affected and cause the lead to a number of amplifications and feedbacks. Thereby
releasing more CO2 to the atmosphere. Increases in global temperature also
affect ocean temperatures, modifying oceanic ecosystems and having the
potential to disrupt the oceanic carbon cycle, limiting the ocean’s capability to
absorb and store carbon.</span>
The lack of centrioles in nerve cells prevents them from undergoing mitosis and meiosis, which prevents them from dividing. Nerve cells do not divide throughout their lives and do not lengthen without doing so.

What is nerve cells?</h3>
The central nervous system is constantly receiving information about the external and internal environment (in the form of sequences of action potentials) from nerve cells, also known as neurons.
Nerve cells are “excitable” cells that may convert a range of stimuli into electrical impulses (CNS). Despite the complexity of the nervous system, neurons and glial cells are the only two types of nerve cells that make up nervous tissue.
The structural and operational components of the nervous system are called neurons. Nerve impulses are electrical signals that are transmitted by them. Neuronal support is provided by glial cells.
Therefore, nerve cells do not reproduce and, if damaged by injury or disease, are lost forever.

A
Explanation:
volume of liquid is same as volume of container where as gas occupies whole volume of container
<span>The release of large quantities of merozoites into circulation at one time is due to a form of reproduction by Plasmodium known as exoerythrocytic schizogony.</span> <span>The intracellular parasite (inside the hepatocytes) undergoes an asexual replication known as exoerythrocytic schizogony. Exoerythrocytic schizogony culminates in the production of merozoites which are released into the bloodstream. This is the end of the asexual reproductive stage. The next target is the red blood cells<span> where the merozoites become gametocytes.</span></span>
