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.
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.

Would a light source be considered an internal or external stimulus?
For plants, light is an external stimulant. Phototropism is a response to light that plants have. The plant responds by orienting its growth in the direction of the light.
What is stimulus?A stimulus is an occasion or any change in the environment that causes an organ or tissue to have a certain functional response.
An external or internal trigger is possible. Sensitive to external stimuli like sound and touch are sense organs like the ear and sensory receptors like those in the skin.
Direct one-to-one stimulus-response reactions are the most basic sort of response. The stimulus is a change in the environment, and the response is how the organism responds to it.
A stimulation that comes from outside the organism is known as an external stimulus. Light is one example of an outside stimulation. Although it comes from outside the body, it has an impact there as well.
Thus, it can be concluded that light is an external stimulus.

The use of restriction enzymes and electrophoresis to generate a map of the DNA molecule is known as
The use of restriction enzymes and electrophoresis to generate a map of the DNA molecule is known as RESTRICTION MAPPING. This technique is used to map an unknown fragment of DNA.
Restriction enzymes are enzymes that cut a DNA fragment at specific nucleotides sites, thereby generally smaller fragments of DNA.
Restriction mapping is a strategy used to map unknown fragments of DNA by digesting them into smaller fragments and then identifying the specific sites of the DNA breakpoints.
Restriction mapping can then be used to create a diagram of fragments of DNA marked with specific sites where they are cut by specific restriction enzymes.

The cerebral nuclei are also called the basal nuclei and sometimes are incorrectly called the basal ganglia. Why is this incorrect
It is incorrect to name basal nuclei as basal ganglia because the term 'ganglia' refers to clusters of cell bodies in the peripheral nervous system (PNS). The basal nuclei are a group of subcortical nuclei.
The basal nuclei are a group of subcortical nuclei located deep in the cerebral hemisphere and midbrain.
The basal nuclei can be defined as a region of the brain that is involved in muscle coordination and movement.
The term ganglia make reference to a group of neurons outside of the central nervous system in the peripheral nervous system (PNS).

Answer:
The correct answer is C (The change of color allowed them to hide better from predators)
Explanation:
Before, the deer mice were easy prey for predators since their color stood out and the predators could find them. Therefore, the change of color allowed them to hide better from predators. You may be tempted to answer a, but if you read carefully it says "The change of color camouflaged them, which helped them HUNT better." Clearly A is wrong since deer mice don't really hunt.

define osmoregulation
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.

Which of the following is NOT an accessory gland of the male reproductive system?
Answer:
a. Testosterone gland
Explanation:post protected
Testosterone gland is not an accessory gland of the male reproductive system.
What is Testosterone gland?Testosterone is a hormone that is primarily produced in the testicles in males and in small amounts in the ovaries and adrenal glands in females. It is a vital hormone that plays a critical role in the development of male reproductive tissues and secondary sexual characteristics, such as muscle mass, bone density, and body hair growth.
Testosterone is also essential for maintaining sex drive and overall physical health in both men and women. The production of testosterone is regulated by the hypothalamus and pituitary gland in the brain, which release signals to the testes to produce testosterone.
Certain medical conditions, lifestyle factors, and aging can affect testosterone production and levels, which can have significant impacts on health and wellbeing. Treatment options are available to address testosterone deficiencies and imbalances.

glial cells that surround the neurons in ganglia are:
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.
