Answer:

Microtubules.

Explanation:

The main cytoskeleton of the cell is micro tubules, micro filaments and intermediate filaments. This structure helps to provide the stability and maintains the cell shape.

Microtubules are made of the polymers of tubulin. The microtubules are hollow shape like protein that forms the main part of the cyoskeleton. The microtubules maintains the cell shape and allows the movement of the cellular organelles of the cell.

Thus, the correct answer is microtubules.

Making an analogy between hearing and vision, the auditory hair cells in the_____ are similar to the _____ in the _____
TiliK225 [7]

Answer;

-Cochlea; rods and cones; retina

Making an analogy between hearing and vision, the auditory hair cells in the cochlea are similar to the rods and cones in the retina.

Explanation;

-There are two types of photoreceptors in the human retina, rods and cones.  Rods are responsible for vision at low light levels (scotopic vision). They do not mediate color vision, and have a low spatial acuity.

-Cones are active at higher light levels (photopic vision), are capable of color vision and are responsible for high spatial acuity. The central fovea is populated exclusively by cones.

The cochlea is a portion of the inner ear that looks like a snail shell. It receives sound in the form of vibrations, which cause the stereocilia to move. The stereocilia then convert these vibrations into nerve impulses which are taken up to the brain to be interpreted.

Add a metabolic poison to the water to block any active metabolism and see if the seed germinates the same as without the poison.

  • The percent increase in mass decreases with rising temperature. As temperature rises, its value approaches that of the percent increase in mass.
  • There are two types of requirements for microbial growth: physical and chemical. Osmotic pressure, pH, and temperature are examples of physical factors.
  • Water, supplies of carbon and nitrogen, minerals, oxygen, and organic growth stimulants are all chemical necessities.
  • hence by using poison to block the active metabolism of seed the chemical growth will be restricted. If the seed still swells this means that it is a physical process.
  • If the seed swelling stops then the process is considered chemical.

What are the dangers to the nervous system and consequences for a person's health while using ecstasy?
salantis [7]

Answer:

Effects of Ecstasy on the nervous system:

- stimulant

- psychedelic

- neurotoxic

- abnormal neurotransmitter function  

- injured cognitive functions (e.g., sleep and pain control)

Explanation:

Ecstasy, also known as MDMA (3,4Methylenedioxymethamphetamine), is a stimulant and psychedelic drug that may exhibit neurotoxic effects. This amphetamine analog (i.e, drug based upon the amphetamine structure) has several effects on the nervous system which are caused by the increase in the activity of three major neurotransmitters: serotonin, dopamine, and norepinephrine. It has been shown that Ecstasy alters the central nervous system, producing neurotoxic effects and affecting brain functions including, among others, cognitive functioning and development, neuroendocrine release mechanisms, sleep control, pain control, etc.
