Human reproduction is when an egg cell from a woman and sperm cell from a man unite and develop to form a baby. A fertilized egg is implanted in the uterus and grows into the unborn baby. Human reproduction naturally takes place as internal fertilization by sexual intercourse.

Janis tore a ligament in her ankle. Until the injury heals, she is at most risk for which of the following? dislocating bones lo
bulgar [2K]

Answer:

The correct answer is ''dislocating bones.''

Explanation:

When the bone " pops out" or dislodges from its place (joint), a dislocation occurs. An ankle dislocation, like any other joint, occurs when the 2 articular surfaces of the ankle separate, in this case when the talus ( together with the rest of the foot) " pops out of place" and is no longer in contact with the surface of the tibia-fibula. This leads to the complete breakdown of the ligaments that hold the joint in place, causing the bones to " pops out." Producing significant deformities in the affected joint.

Your New Year's resolution is to drastically reduce the amount of cholesterol in your diet by eating less meat and more fruits a
grin007 [14]

After a few months of eating less meat and more fruits and vegetable, the liver will respond by producing more cholesterol.

<h3>What is body homeostasis?</h3>

The term body homeostasis makes reference to the internal equilibrium (homeostasis) of the body.

Body homeostasis may involve the production of certain substances when they are not consumed from the diet.

In this case, it is possible to increase cholesterol levels by having certain healthy habits (food habits).

Animals with a three-chambered heart would include:_______
Setler79 [48]

Animals with a three-chambered heart would include Amphibians.

  • Amphibians have three-chambered which comprises of two Atria and one ventricle. Examples of Amphibians include Frog, Toads, Salamanders.
  • In Amphibians heart blood from the single ventricle travels to the lungs, skin, and body, where it is oxygenated. Before being pumped out of the heart, deoxygenated and oxygenated blood are mixed in the ventricle.
  • This is because the Amphibians have low rate of metabolism and thus requires less oxygen for their metabolism.
  • As a result heart's load to deliver oxygenated blood to body is lowered.

Thus, from the above pointers we can conclude that only Amphibians from the option have three-chambered heart.

ehidna [41]

Answer:

The yellow leaf was not exposed to the sun so it can't produce sugar.

Explanation:

The yellow region of the leaf didn't produce sugar because it wasn't exposed to sunlight. Part of the leaf was exposed to the sun, thus this leaf produced sugar, while the yellow part of the leaf did not because it was not exposed to the sunlight.

Many receptor tyrosine kinase pathways have mapk as a downstream signaling component. mapk can phosphorylate target proteins. wh
Lapatulllka [165]

A protein kinase that is specific to the amino acids serine and threonine is known as a mitogen-activated protein kinase (MAPK or MAP kinase; also known as a serine/threonine-specific protein kinase).

<h3>Mitogen-activated protein kinase :</h3>

A small number of cell surface receptors can ultimately generate a large intracellular response due to activation of kinase cascades.

In order to trigger an appropriate physiological response, such as cellular proliferation, differentiation, development, inflammatory reactions, and death in mammalian cells, MAPK pathways relay, amplify, and integrate information from a variety of stimuli.

Tyrosine phosphorylation, specifically numerous tyrosines on each RTK in the dimer, is how cross-linking triggers the tyrosine kinase activity in these RTKs. The term "cross-phosphorylation" refers to this action.

The activation of a MAPKKKK or MAPKKK by stimulation of plasma membrane receptors is the initial stage of signal transduction. The MAPKKK then phosphorylates two serine or threonine residues in the S/T-X5-S/T (X is any amino acid) motif of its activation loop, activating a downstream MAPKK.
