Microglial cells are most similar to found in our skin cells.
What is microglial cells?Neuroglia (glial cells) of the microglia kind are found all over the brain and spinal cord. Between 10% and 15% of all brain cells are microglia. They serve as the first and primary active immune defense in the central nervous system because they are resident macrophage cells (CNS).
Throughout the CNS, microglia (and other neuroglia, including astrocytes) are dispersed in sizable, non-overlapping areas. Microglia are essential for maintaining the overall health of the brain since they are constantly scouring the CNS for plaques, infected cells, and damaged or superfluous neurons and synapses.
Microglia are particularly sensitive to even minute pathogenic changes in the CNS because these processes must be effective to prevent potentially fatal harm.
Therefore, Microglial cells are most similar to found in our skin cells.

The Sun's spectrum contains spectral lines from neutral sodium and calcium as well as ionized magnesium and iron. Of the choices below, which could be the surface temperature of the Sun?
Answers
Answer: 5800 K
Explanation:
The Sun is a star found in the center of the solar system amd almost a perfect sphere of plasma. It constitutes the largest source of electromagnetic radiation in this planetary system and it also generates a magnetic field through a dynamo process. About three-quarters of the Sun's mass consists of hydrogen while the rest is mainly helium, with much smaller amounts of other elements such as oxygen, carbon, neon and iron.
Such as any other star, the Sun has a spherical shape, and because of its slow rotation movement, it also has a slight polar flattening. All the matter that constitutes it is attracted towards the center by its own gravitational force. However, the plasma that forms the Sun is in balance, since the increasing pressure in the solar interior compensates the gravitational attraction, which generates a hydrostatic balance. These enormous pressures are produced due to the density of the material in its nucleus and to the enormous temperatures that occur in it thanks to the thermonuclear reactions that take place there. There is, besides this thermal contribution, one of photonic origin which is the radiation pressure caused by the enormous flow of photons emitted in the center of the Sun.
The quantum mechanics allows to calculate the spectral lines of the atoms and molecules that compose the solar atmosphere at any temperature, however the calculation is not easy. For this reason there are several heavy atomic elements with spectral lines that have transition probabilities that are still uncertain.
However, despite being complicated, scientists have determined that the surface temperature of the Sun is around 5800 K.

What is cellular respiration?The process through which food, in the form of sugar (glucose), is converted into energy within cells is known as cellular respiration. It gives cells the energy they require to work. Food would be completely useless if living beings couldn't obtain the energy they required from it. No matter the type or quantity of nourishment, all living beings will eventually perish.
There are two types of cellular respiration and that is aerobic respiration and anaerobic respiration.
Both the cytosol and mitochondria of cells participate in cellular respiration. While pyruvate oxidation, the Krebs cycle, and oxidative phosphorylation take place in the mitochondrion, glycolysis happens in the cytosol.

Why are scorpions florescent to black light? How might it help them survive?
Answers
Answer:
Well, something in the scorpions' exoskeleton causes them to glow. The fluorescence makes their bodies more sensitive to light, so it's easier to find a shady hiding spot to survive in.
Explanation:
Answer:
Certian molecules in the scorpians cuticle are what glow. The exoskeleton absorbs the longer wavelengths of the uv light and emit the light in blue-green wavelengths which makes it glow.
This glow helps protect scorpians from sunlight, and helps them find each other.

Explanation:
what property of water makes water so helpful in riding the body of wastes?
A) Water is versatile solvent.
B) Water is expands upon freezing
C) Water cohesive forces surface tension upon its surface
D) Water has a high specific heat.
Answers
Answer:
A) Water is versatile solvent.
Explanation:
Water is a chemical compound consisting of one atom of oxygen (O) bonded chemically to two atoms of hydrogen (H). It is a unique substance due to its properties. Water is a polar molecule i.e. has both positively and negatively charged ends, hence, making one of its properties of being a UNIVERSAL SOLVENT possible.
Water is said to be a universal solvent because it can dissolve more solid substances than any other liquid. This outstanding property of water is key to its function in getting rid of wastes because these wastes readily dissolve in water and are transported or carried to sites of exit from the body. For example, urea is a waste in humans, which gets dissolved in water to form URINE that is excreted.
Which stage in the cell cycle occurs only once in both mitosis and meiosis?
Ⓐ cytokinesis
Ⓑ interphase
Ⓒ prophase
Ⓓ telophase
Answers
interphase occurs only once in both meiosis and mitosis
The stage in the cell cycle that occurs only once, in both mitosis and meiosis, is interphase. The correct option is B.
What is the cell cycle?The cell cycle is a process of the growth and division of cells. The normal cell performs these cell cycles for division and growth. The sex cells perform the cell cycle and meiosis when reproduction occurs.
The cell cycle completes in a four-stages:
1. gap 1, or G1, stage- cell increase in size.
2. synthesis, or S, stage- DNA copy.
3. gap 2, or G2, stage- prepare to divide.
4. mitosis, or M, stage- division occurs.
In mitosis, the process of interphase occurs. In interphase, the cell divides and the chromosomes are copied, and it prepares for division.
Thus, the correct option is B, interphase.
