Answer:
To back away
Explanation:
To back away because magnets are different and is they are put the wrong the way it moves back
Answer: b. The use of protein as an energy source is greater for endurance atheletes than those who body build or lift weights.
Explanation:
Proteins are the biomolecules. They are composed of polymers of amino acids. It is required by the body to repair tissues and build muscles, bones, and necessary component of skin, and cartilage.
The body of athletes require more protein than body builder or weight lifters. This is because during athletic practices like running, swimming and others the muscular mass should be strong enough to conduct long continous practice. The muscle mass is build up by proteins. The muscles may experience lack of oxygen during regular practice and may become weak. Thus require more protein so that the strength may remain maintained.
Answer:
1. import and export of nutrients and wastes
2. cell signaling
3. cell recognition
4. cell growth and motility
Explanation:
Plasma membranes are selectively permeable which means it only allows selective molecules to cross through it. So the plasma membrane helps in the import and export of nutrients by simple diffusion, facilitated diffusion or through active transport.
There are membrane protein embedded in the plasma membrane which have different role. Some help in cell signaling like GPCR, some help in cell recognition and some act and transporter proteins.
The plasma membrane is also responsible for cell growth and motility because it allow the raw materials and signals to pass through it which is required by the cell to metabolize and grow. So 1,2,3,4 is the correct answer.
Answer: C
Explanation: I'm not one hundred percent sure I know the context of this question, but biodiversity in an ecosystem means there's a wide variety of organisms, and a hotspot I assume would be an area that has an unusual amount of diversity.
The hypothalamus communicates directly with pituitary gland.
<h3>Hypothalamus?</h3>
Hypothalamus is a small part lied f the brain that is between the inferior and anterior of thalamus. This gland is linked up with the pituitary gland by the stalk-like infundibulum. The pituitary gland comprises of an anterior and posterior lobe and each love produce different hormones in response to signals from the hypothalamus.
posterior lobe contains the ends of nerve cells that is from hypothalamus. The hypothalamus transmitt the hormones directly to the posterior lobe via these nerves, and then the pituitary gland releases them.
Therefore, The hypothalamus communicates directly with pituitary gland.
