Answer:

oligodendrocytes

Explanation:

Glial cells are part of the nervous system. These are helper cells that support the function of the central nervous system (CNS) and can be called oligodendrocytes when they supply myelin to neurons. These cells are responsible for producing the myelin sheath have the function of electrical insulator for CNS neurons. They have extensions that wrap around the axons, producing the myelin sheath.

It is estimated that there are 10 glia cells in the CNS for each neuron, but because of their small size, they occupy half the volume of nervous tissue. They differ in form and function and they are: oligodendrocytes, astrocytes, Schwann cells, ependymal cells, and microglia.

Diffusion continues until

Viktor [21]

Equilibrium.
diffusion occurs due to differences in concentration of substances in different regions. then substances will naturally spread out (due to innate Brownian kinetic energy). the spreading I. e. diffusion will stop until equilibrium is achieved.
note: those substance particles are still moving due to the innate Brownian kinetic energies!

Calcule la molalidad de una<br> 20g Ca Cl₂ en 250g de<br> que contiene<br> solucion<br> H₂O.

ahrayia [7]

Answer:

The solution is 0, 90 molal. See the explanation below, please

Explanation:

Molality is defined as moles of solute in 1 kg of solvent (1000 grams). The following three simple rule must be performed:

We calculate the weight of 1 mol of CaCl2

Weight Ca =40, 078 g

Weight Cl= 35, 453 g

Weight of 1 mol of CaCl2=40, 078g + 2x (35, 453g )= 110, 98g

110, 98 g ---1 mol

25 g---X= (25g x1 mol)/110, 98g= 0,23mol

250g solvent -----0,23 mol CaCl2 (the solute)

1000g solvent ----X = (1000g x0,23mol)/250g =0,90 mol solute

The solution is 0,90 molal

Which of the following accurately describes the role of energy in cellular respiration?

zmey [24]

Answer:

The correct answer is option energy is a product.

Explanation:

Cellular respiration is a process in which oxidation of food or glucose takes place to produce energy. This process proceeds in four processes: glycolysis, oxidative carboxylation, Krebs cycle and electron transport chain.

All of this process produces energy in the form of ATP or energy equivalents like NADH and FADH₂.

1. Glycolysis produces- 2 ATP, 2 NADH,

2. Oxidative carboxylation produces- 2 NADH,

3. Krebs cycle produces- 2 ATP, 6 NADH AND 2 FADH₂ and

4. Electron transport chain produces at last- 24 ATP from these reducing equivalents.

Thus, option energy is a product is a correct option.

A client has been diagnosed with aplastic anemia. the nurse is aware that the client’s lab results will identify:

shutvik [7]

In aplastic anemia, then lab result will be decreased in all blood component( white blood cells, red blood cells, and thrombocyte).
Aplastic anemia is caused by the bone marrow failure. Bone marrow is the place that produces blood cells, so the decrease wouldn't be in the red blood cell only, but in other blood cells too. There shouldn't be any iron deficiency or decreases in the mean corpuscular volume
