which feature of stem cells enable them to replace cells in tissues such as skin?

Answers

That is right!!!!! Hope that helped

The feature of stem cell which enable them to replace cell in tissues are that they can divide indefinitely to generate new cells and they can convert into the different types of cells that make up the body as they divide.

What is a stem cell ?

A stem cell is a cell that has the unique capacity to grow into different types of cells in the body.

They may be utilised in the future to replace cells and tissues that have been damaged or destroyed owing to illness.

Stem cells are classified into three types which are Embryonic stem cells, Adult stem cells, Induced pluripotent stem cells.

Embryonic stem cells provide new cells to an embryo as it grows and develops into a newborn.

Adult stem cells generate new cells as an organism matures and replace damaged ones.

Induced stem cells are stem cells created in the laboratory by scientists.

The most important feature that permits a gene to act as a molecular clock is The most important feature that permits a gene to act as a molecular clock is having a reliable average rate of mutation. having a larger proportion of exonic DNA than of intronic DNA. its being acted upon by natural selection. having a large number of base pairs. its recent origin by a gene duplication event

Answers

Answer:

The answer is "The first choice".

Explanation:

The hypothesis of such a molecular clock says because DNA and protein sequences develop at a pace generally constant over time as well as between different organisms. The whole idea is thus incredibly beneficial and for estimation of the historical periods, if the molecular biological hypothesis is valid, then the most significant feature enabling DNA to act as a molecular clock it has a reliable mean mutation.

A utility company has proposed building a natural gas power plant next to a lake. The picture below shows the proposed power plant.






The company claims burning natural gas will release only harmless gases such as water vapor (H2O) and carbon dioxide (CO2). Why would environmental scientists disagree with this claim?

A
The emission of carbon dioxide leads to rapid cooling of the Earth’s lakes and oceans.

B
The emission of carbon dioxide leads to an increase in the temperature of the atmosphere.

During the relative refractory period, _______. During the relative refractory period, _______. another action potential can be generated provided the stimulus is relatively smaller than the original stimulus. another action potential can be generated provided the stimulus is large enough. the flow of potassium is also depolarizing the neuron. a second action potential cannot be generated, no matter how strong the stimulus.

Answers

Answer:  

During the relative refractory period, another action potential can be generated provided the stimulus is large enough.

Explanation:

The relative refractory period is the time after an action potential where the sodium channels are transitioning from inactivated channels to closed ones. In other words, voltage-gated Na+ channels have two gates, an external one and an internal one. During repolarization, the outer gate is blocking the entrance, and the internal one is open. So the channel is inactivated. When the inner gate is closed, the Na+ channel is closed.

During the relative refractory period, a second action potential can happen, but the stimulus has to be large enough to do it since the membrane is hyperpolarized, that is to say, the membrane potential is more negative than the resting action potential. The cell needs more Na+ ions to produce the second action potential.

Adrenergic receptors Select one: a. can be activated by the release of epinephrine. b. have two structural forms - muscarinic and nicotinic. c. when activated stimulate skeletal muscles to contract. d. can be found in both the sympathetic and parasympathetic divisions. e. are activated by the release of acetylcholine.

Answers

Answer:

The correct answer is  a. can be activated by the release of epinephrine.

Explanation:

Epinephrine is a hormone and neurotransmitter naturally secreted by the body through the adrenal glands, synthesized and stored in the adrenal medulla and released into the systemic circulation. Epinephrine is a non-selective adrenergic agonist, stimulating alpha1-, alpha2, beta1, and beta2-adrenergic receptors. The systemic actions of catecholamines are mediated by the binding of these compounds to plasma membrane receptors, of the GPCR type widely distributed throughout the body and known as adrenergic receptors, which are activated by the catecholamines adrenaline (epinephrine) and noradrenaline . These receptors cause different effects depending on the G protein subtypes to which they are associated and the signal transduction mechanism linked to the specific G protein.

It’s after the egg and sperm cell have combined. So it’s “has the complete genetic information to form an adult”.

It would be half before it received the sperm so it’s not the first one. There is clearly NO sign of differentiation so it isn’t the second one. And the cell is the first in the given series so it’s not identical to a parent cell.
