The correct answer is: Induction, because this could be easily changed by changing the cell's environment.

Cell differentiation (process by which cell becomes specialized) can be under the influence of many factors:

• Cytoplasmic influence because cytoplasm can influence and control the behaviour of nuclear genes.

• Embryonic induction-changing the cell environment

For example: if cells from one region of the embryo are transplanted to some other region that transplant will most likely differentiate according to the chemical regulators of the surrounding cells.  

• Proteins present in a cell influences its differentiation

• Cell-Cell interactions via cell-cell adhesion and signalling molecules.

The nurse is orienting a new RN in the care of a patient with respiratory distress due to emphysema. The patient is being treate
nika2105 [10]

The question is incorrect. The correct question is as follows:

The nurse is orienting a new RN in the care of a patient with respiratory distress due to emphysema. The patient is being treated with O2 via a Venturi mask with 35% oxygen. Which statement by the new RN indicates that teaching has been effective, when the nurse questions the new RN about the use of the Venturi mask?

a. "A nasal cannula will dry the mucous membranes and cause an increased risk of infection."

b. "Her alveoli cannot absorb higher levels of O2 because of the emphysema."

c. "Her alveoli have been damaged and may rupture with higher doses of O2."

d. "Her respiratory center requires low O2 concentration to stimulate breathing."

Answer:

Her respiratory center requires low O2 concentration to stimulate breathing."

Explanation:

COPD ( Chronic obstructive pulmonary disease) may be defined as the combination of the different lung disease that might create problem in the respiration process.

The venturi mask is used in the medical condition to provide the proper amount of oxygen to the patient. In emphysema the individual suffered from the hypoxemia means low oxygen level in the body. The low oxygen is required to the patient and high oxygen level will disturb the normal process of breathing.

Thus, the correct answer is option (d).

What are the three types of cell signaling
PIT_PIT [208]

Answer:

there are 4: paracrine signaling, autocrine signaling, endocrine signaling, and synaptic signaling

Explanation:

paracrine:cells that are near one another communicate through the release of chemical messengers 

autocrine: a cell signals to itself, releasing a ligand that binds to receptors on its own surface 

endocrine:When cells need to transmit signals over long distances, they often use the circulatory system as a distribution network for the messages they send. 

synaptic: nerve cells transmit signals. The junction between two nerve cells where signal transmission occurs.

<span>The formation of the fertilization envelope (slow-block to polyspermy) requires an increase in the availability of </span>calcium ions.

Slow-block to polyspermy is also called cortical reaction. In this reaction, the sperm will be permanently blocked by cortical granules. The release of calcium ion will trigger this reaction.
