Answer: Option (D) is the correct answer.
Explanation:
A hypothesis is defined as an educated guess with the help of which an individual might predict what would happen in a certain experiment or situation.
When we evaluate some data with the help of analytical and reasoning approach then it is known as analyzing data.
Stating the problem means defining the problem so that others can also get to known the problem.
Therefore, we can conclude that when Jeremy is conducting an experiment and has just made an educated guess as to what will happen in the experiment then making a hypothesis is the step of the given scientific method.
Answer:
During capillary exchange , red blood cells are the substance that is not sent out to the tissue.
Explanation:
Capillaries have thin walled cell which can only exchange glucose which is a monosaccharide, water molecule, carbondioxide and oxygen gas. These substances are exchanged because they are small in size while red blood cells are not exchanged due to large in size.
Nucleotides is the name of the monomer
Explanation:
Answer:
The correct answer is: β1 adrenergic receptor activation. Increased in cAMP lead to increased amounts of Na influx (though if channels) and calcium influx of pacemaker cells. This increases the frequency of APs of the pacemaker and increases the rate of contraction.
Explanation:
cAMP generated in response to β1 adrenergic receptors,results in excitation contraction coupling by initiating PKA and causing phosphorylation of L type Ca2+ channels and ryanodine receptors. This increases the concentration of intracellular Ca2+ ions in atrial cells, ventricular cells and AV pacemaker cells. This increase in firing rate. As a result rate of contraction increases.
The correct answer is your kidneys because the organs most intimately related to the substances carried by the blood are the kidneys, which filter out nitrogenous wastes and regulate concentration of salts; the spleen<span>, which removes worn red blood cells, or lymphocytes; and the </span>liver<span>, which contributes clotting factors to the blood, helps to control </span><span>blood sugar</span>
