What are the functions of glial cells?Glia, also called glial cells (gliocytes) or neuroglia, are non-neuronal cells in the central nervous system (brain and spinal cord) and the peripheral nervous system that do not produce electrical impulses.
Functions include: clean up brain "debris"; transport nutrients to neurons; hold neurons in place; digest parts of dead neurons; regulate content of extracellular space; promote synaptic connections.
Any of the cells that hold nerve cells in place and help them work the way they should. The types of glial cells include oligodendrocytes, astrocytes, microglia, and ependymal cells.

Calculate the kinetic energy of a
30 g bullet fired at 200 m/s.
Answers
Step 1: Identify the formula needed to solve this problem.
The formula for kinetic energy (KE) is:
KE = 1/2m~v^2
m = mass
v = velocity
Step 2: Make a list of the values given in the question.
mass (m) = 30 g
velocity (v) = 200 m/s
[tex] \frac{1}{2} m {v}^{2} \\ \frac{1}{2} \times 30 \times {200}^{2} \\ 15 \times 40000 \\ = 600000[/tex]
Answer:
6 × 10⁵ J
Explanation:
Kinetic Energy of a moving mass is defined as, half of the product of it's mass and the square of it's velocity.
[tex] \boxed{ \mathsf{K.E. = \frac{1}{2} m( {v})^{2} }}[/tex]
Mass of the bullet (m) = 30 gvelocity (v) = 200 m/ s[tex] \implies\mathsf{K.E. = \frac{1}{2} \times 30 \times ( {200})^{2} }[/tex]
[tex] \implies\mathsf{K.E. = 15 \times 4 \times {10}^{4} }[/tex]
[tex] \implies\mathsf{K.E. = 60 \times {10}^{4} }[/tex]
[tex] \implies \underline{\mathsf{K.E. = 6 \times {10}^{5} J }}[/tex]
what will happen if phase changes didn't exist?
Answers
Answer:
Matter can exist in one of several different states, including a gas, liquid, or solid state. The amount of energy in molecules of matter determines the state of matter.
A gas is a state of matter in which atoms or molecules have enough energy to move freely. The molecules come into contact with one another only when they randomly collide.
A liquid is a state of matter in which atoms or molecules are constantly in contact but have enough energy to keep changing positions relative to one another.
A solid is a state of matter in which atoms or molecules do not have enough energy to move. They are constantly in contact and in fixed positions relative to one another.

Think about the importance of energy. Without a source of energy organisms cannot respond, build, reproduce, or carry out most of the functions of living things. From where does our energy come? Explain how Photosynthesis and Cellular Respiration are important in your everyday life. Be Scientific! 5-6 sentences!
Answers
Answer:
Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathway through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere. The exchange of carbon dioxide and oxygen during photosynthesis and cellular respiration worldwide helps to keep atmospheric oxygen and carbon dioxide at stable levels.
Photosynthesis is a very important process in plants. It helps in the formation of glucose in plants. Cellular respiration takes place in human beings.
What is energy?Energy is the ability to do work. All living organisms require energy to do work. Energy is transformed to chemical energy in plant cells through a process called photosynthesis.
Plants utilise the chemical energy stored during photosynthesis in their cellular respiration for essential life functions. Energy is changed during both photosynthesis and cellular respiration.
The light-dependent and light-independent processes of photosynthesis are also important for plant management.
Therefore, Photosynthesis is a very important process in plants. It helps in the formation of glucose in plants. Cellular respiration takes place in human beings.

Through the mitotic process, two identical diploid daughter cells are produced. Mitosis is preceeded by the interphase and followed by cytokinesis. 7) b. / 8) a. / 9) b. / 10) b. / 11) c. / 12) a.
-------------------------------------------------
The interphase occurs before cell division. It is composed of the G1, S, and G2 stages.
During the G1 stage, the cell duplicates in size. The organelles and other cytoplasmatic structures duplicate. The high intense biochemical activity is characteristic of this stage. During the S stage occurs the DNI molecule replication process. At this point, also happens the synthesis of histones and other associated proteins. The G2 stage is the final one before the cellular division. Here begins the slow process of DNI condensation. Duplication of centrioles completes. Structures such as spindle fibers are assembled.
Mitosis is a process by which, from a diploid somatic cell (2n), two daughter diploid cells (2n) are produced.
Daughter cells are identical to the original cell.
Mitosis occurs in only one phase, divided into four stages.
In the prophase, it occurs chromosomes condensation and nuclear membrane breaks. During the metaphase, chromosomes are taken toward the center of the cell by the spindle apparatus. Once in the equatorial plane, chromosomes line up.Each chromatid joins with a microtubule of opposites poles.
In Anaphase, bonds between chromatids break. They separate and migrate to the opposite poles. In telophase, duplicated chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole.Finally, cytokinesis occurs.

What is Chromosome?Chromosomes are the thread-like structure made up of protein (histones) and a single molecule of DNA which carries all the genetic information in it. It is located in nucleus.
Human have 23 pairs of chromosomes including pairs of 22 chromosomes (i.e. Autosomal Chromosomes) and 1 pair of Sex Chromosome (XX or XY).
Each pair contain two Chromosomes inheriting from the parents, half from mother and another half from the father.
Each chromosome have a point which is constricted in the middle known as Centromere, which divides chromosomes into two arms i.e. short arm “p” and long arm “q”.
Thus, Nucleotide, Gene, Chromosome and Genome is the levels of genetic information in order from smallest to largest.
