What steps are involved when a planarian needs to generate new cells

Biology
1 answer:
Nataly [62]2 years ago
6 0

Answer:

Using this technique, which they termed 'chemical amputation', the team induced lesions in planaria and investigated which genes were activated over the course of the regeneration process. The pharynx lacks neoblasts, but cells near the wound quickly start dividing and regenerate the amputated organ.

How might the ATP produced in a muscle cell be impacted by a worldwide drought.
Nina [5.8K]
With each contraction cycle, actin moves relative to myosin. ... ATP can then attach to myosin, which allows the cross-bridge cycle to start again; further muscle contraction can occur. Therefore, without ATP, muscles would remain in their contracted state, rather than their relaxed state.

After suffering a head injury, doctors discover that your
VikaD [51]

Answer:

1. You will be unable to smell

3. Your olfactory receptor cells will no longer be able to respond  to molecules trapped in the mucus.

Explanation:

The Olfactory receptors are the receptors present in the olfactory neurons which detect different odorants or smell.

The olfactory receptors are embedded in the epithelium or mucous lining of the nose in which one extension of the cell body reaches the epithelium surface and branches into cilia like structures which sense the odour.

If the axons of the olfactory cells are broken then the cells will not be able to respond to the molecules trapped in the mucus and thus no detection of odour. The signal will not be generated in response and thus will not be sent to the brain. Thus, the person will not be able to smell.

Thus, Options-1 and 3 are correct.

A biological theory, like the theory of evolution, that is widely accepted and supported by so many observations and experiments
Crank

A biological theory, like the theory of evolution, that is widely accepted and supported by so many observations and experiments may be referred to as a principle or a law.

<h3>What is a Law?</h3>

This refers to statements which describes or predict a range of natural phenomena as a result of repeated experiments which has been performed and the authenticity has been prove by peers and other individuals.

A law is also referred to as principle and has been observed to be always true unlike due to the repeated scientific methods being done approving of its validity thereby making law the correct choice.

_______ research has the potential to significantly impact the development of disease-modifying treatments for Parkinson's disea
nydimaria [60]

<u>Stem cell </u>research has the potential to significantly impact the development of disease-modifying treatments for Parkinson’s disease with considerable progress made in creating dopamine-progressing cells.

Explanation:

Parkinson’s disease, a neurodegenerative disease, leads to reduction of dopamine (a neurochemical messenger which carries messages involving thinking and body movements to brain) in the body because the disease will target and kill dopamine-producing nerve cells (neurons). This leads to loss of movement and thinking abilities which are activated by dopamine.

Stem cells research is done to study about the prospects of stem cells in stem cell therapy for Parkinson’s patients as a viable source of new dopamine nerve cells. Research has been involved in growing stem cells to replace or regenerate dopamine-producing nerve cells by using embryonic stem cells or induced pluripotent stem cells as a treatment modality in Parkinson’s disease.

liberstina [14]

Answer:

Meristematic tissue

Explanation:
