Answer:
The correct answer is- make a prediction
Explanation:
A hypothesis can be defined as an explanation of any observation which can be confirmed by experiments and prediction is the guess about the future result of any observation.
As here a biologist hypothesized that the sound produced by frog is mating calls than the next step of the biologist would be to make a prediction about response of that mating call by female frogs. This is called hypothesis prediction method.
Therefore the right answer is- biologist will make a prediction.
We can get amino acids from eating food that contain proteins.
Proteins are made up of chains of amino acids. During digestion, the proteins are broken down into amino acids.
Answer:
women inherit the X chromosomes and men inherit the Y chromosomes
Explanation:
Answer: a. rna interference.
Rna interference <span> was known by other
names like <span>co-suppression because
it </span>has become evident that RNAi has immense potential in inhibiting desired
genes by neutralizing targeted mRNA molecules</span> Two types of small ribonucleic acid (RNA) molecules that are central to RNA interference
are miRNA and <span>siRNA. </span>
C. Endothelial contraction
Explanation:
The primary function of the vascular endothelium is to act as an effective barrier system and controls the diffusion of micro and macromolecules and keep the vascular compartments and interstitial spaces intact.
When this endothelial barrier system fails to function, exudation or leakage of fluid, solutes and proteins from the vasculature takes place leading to accumulation in the interstitial spaces.
Failure of endothelial vasculature like endothelial contraction occurs due to binding with mediators or specific receptors like histamine or leukotrienes or also due to any injury.
When there is an endothelial contraction, the intercellular gaps present in between postcapillary venules widen giving space for the fluid leaked from the vasculature to accumulate.
This exudation of fluids is a factor of an acute inflammatory process. In the above case, the high neutrophil count in the pleural fluid confirms a lung inflammatory process. The neutrophils act as the first line of defence against the inflammation.
