What type of necrosis results from ischemia of neurons and glial cells?

<span>The type of necrosis that typically results from ischemia of neurons and glial cells is liquefactive necrosis. Ischemia is an inadequate supply or blood, which causes neurons and glial cells to die. The dead neurons and glial cells result in the tissues becoming a liquid mass, hence the name liquefactive necrosis.</span>

The type of necrosis from the ischemia (loss of blood supply) of neurons and glial cells is liquefactive necrosis. Liquefactive necrosis is characterized by loss of tissue structure grossly and microscopically and only fragments of cells as well as neutrophilic (if acute) or lymphocytic (if chronic) cells. Liquefactive necrosis occurs only in the brain and in suppurative processes such as abscesses. 

Other types of necrosis include coagulation necrosis (tissue structure is preserved), gangrenous necrosis (transmural necrosis), enzymatic fat necrosis (in breast tissue and pancreas), and fibrinolytic necrosis (in blood vessels).

Why are groups of small cells better than one large cell at moving material in
kirill [66]

The groups of small cells better than one large cell at moving material in  and out because they have a greater surface-to-volume ratio.

<u>Option: A</u>

<u>Explanation:</u>

This happened so as these smaller cells, unlike bigger cells, can quickly and willingly enter and move through the membranes of other cell membranes and permeable coverings. For these smaller and mini cells, it is also important to penetrate and move effectively, distribute and transport products and materials such as nutrients, oxygen and waste across the body without requiring enough energy and saving less space. They are cheaper, more effective and use less room for simple reasons, and most notably deplete less resources.

Hello!

An initial observation is the first thing a scientist notices about a topic before conducting the experiment. We can see that it is the first thing in the paragraph in this case, that dandelions grow as unwanted weeds in many lawns.

The hypothesis is the guess about the result of an experiment made before the experiment is conducted. In this case, it is that a weed killer (Killimal) would kill all the dandelions while leaving the grass healthy. This is not specifically a guess made by the scientist, but more like a prediction he wanted to verify.

An independent variable is the variable being changed in the experiment by the scientist. Here, it is whether Killimal was sprayed or not.

The dependent variable is the variable being measured, and the one being affected by the independent variable. His observation would be whether the grass and dandelions would be killed. This is because the weed killer would be directly affecting whether or not these would be killed.

The control variables are ones which are kept the same in the experiment as to not interfere with the final results. In this case, it would be the density of dandelions, the amount of sunlight, and the amount the plants were watered. These were kept exactly the same, as they could've affected the dependent variable if changed.

The control group was the one that is not impacted by the independent variable. The control group makes sure that it actually is the independent variable affecting the dependent, and it isn't some outside unknown variable. This would be the plot without the Killimal.

The experimental group is the one being experimented on from the independent variable. This would be the plot with the Killimal.

Hope this helps!

Answer:

Cell wall: A protective layer covering the outside of the cell. They keep the shape of the plant cell, prevent water loss, and provide support.

golgi apparatus: Transports proteins and lipids around the cell. Often it is called the shipping department of the cell.

chloroplast: Chloroplasts store chlorophyll and this is where photosynthesis takes place in the cell.

Cell membrane: A layer that covers the cell, acts as a gate and determines what comes and goes through the cell. It allows good things in, while keeping others out.

Intermediate filaments: Provides support when when the plant cell comes into contact with other cells.

Ribosome: The part of the cell that is responsible for creating proteins.
