glial cells that surround the neurons in ganglia are:

Answers

Answer:

Explanation:

Satellite cells are small glia that surround neurons' sensory ganglia in the ANS. These resemble the astrocytes of the CNS and assist in regulating the external chemical environment. PNS satellite glia are very sensitive to injury and may exacerbate pathological pain.

Glial cells surrounding the neurons of neurons are satellite cells.

What are the functions of glial cells?

Glial cells are a type of cell that provide physical and chemical support to neurons and maintain their environment. Located in the central nervous system and peripheral nervous system.

Glial cells outnumber neurons in the brain and outnumber them by a ratio of 3:1. Although glial cells also have complex processes extending from their cell bodies, they are generally smaller than neurons and  lack axons and dendrites.

Oligodendrocytes form the myelin sheath around axons. Astrocytes supply neurons with nutrients, maintain their extracellular environment and provide structural support. Microglia clear pathogens and dead cells.

define osmoregulation​

Answers

Answer: OK!

Explanation: Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body fluid) to keep the body fluids from becoming too diluted or concentrated.

now you’ll examine an operon that undergoes negative and positive control. the ara operon in e. coli codes for enzymes that metabolize the sugar arabinose, which e. coli can use for energy. as you can see in the diagram, the regulatory protein arac can act as both an activator and a repressor of the ara operon.

Answers

The lac operon is known to be able to undergoes negative and positive control.

The diagram based on the 4 table arrangement is filled up below (Right to left);

In the presence of arabinose:  initiator, activator,  yes,  yes.

In the absence of arabinose: initiator and operator, repressor, no, no.

If a mutation prevents arabinose from biding to AraC: initiator and operator, repressor, no, no.

If arabinose is present but a mutation and AraD enzyme renders it non-functional: initiator, activator, yes, no.

The metabolism of the sugar arabinose is known to be influenced  by an operon that is said to undergo both positive control and negative control.

Transcription of the ara operon is lead by the regulatory protein AraC, which then bound to the DNA.

When arabinose is present, it binds to AraC, and both parts of the AraC dimer are then also bound to the initiator, making transcription to move foreword.

When arabinose is absent, one part of the AraC dimer is often bounded to the initiator, while the other part is bounded to the operator, thereby hindering transcription.

Explanation:

Onion root tips contain cells that are constantly dividing. Why was it important to use the onion roots tips to observe chromosomes during mitosis rather than a cell from another part of the plant?
a. Because cells in the leaves do not have DNA or chromosomes.
b. Because chromosomes only form during mitosis, one part of cell division
c. Because root cells are naturally purple, so you can see the chromosomes
d. Because cells in the leaves only divide, but do not undergo mitosis.

Answers

Explanation:

the answer to your question is A

Onion roots are used to see mitosis because of rapid growth at the onion tips and at the stage of mitosis,leaves of the plants has division in the cells but there is no mitosis. the correct answer is option D.

What is the significance of mitosis ?

The significance of mitosis is that in the stage the chromosomes are paired and the pairing of this homologous chromosomes makes the chromosomes visible at the equatorial plate.

Leaves do not undergo cell mitosis as they do show the cell division  from various types of tissues but the mitosis is absent and the root cells show rapid division in the lateral sides and because of roots being the active site of division, these are considered more to see mitosis happening.

Thus, mitosis being absent in leaves takes the roots to be considered option.

A. All the energy comes from the sun, so it would make sense that any matter we get would also come ultimately from the sun. Without the sun, no photosynthesis would happen


B. Water and carbon dioxide supply us with the matter and they are the inputs for photosynthesis, and everything starts with photosynthesis


C. Our bodies are made of over 90% water, so we essentially are water which is an input for photosynthesis


D. We are made of carbon-based molecules and that carbon needs to come from somewhere, so the carbon comes from the glucose we eat which came from the carbon dioxide.


E. Glucose is eaten by us which is then used to build oxygen and carbon dioxide molecules that will get released back into the air. We are able to make air which is an example of matter/mass in our biosphere

What is the difference between eukaryotes and prokaryotes?

The main difference between eukaryotes and prokaryotes is that the eukaryotes are well developed and advanced and have different cell organelles and they have different functions in the cell and the prokaryotes are not well developed and they are found in the unicellular organisms.

The unicellular organisms are made of one cell and carry out the processes of life as a single cell and the multicellular organisms are made up of two or more cells that have specific functions to contribute to the life processes.
