Answer:
the messenger RNA (mRNA) is decoded in a ribosome, outside the nucleus, to produce a specific amino acid chain, or polypeptide. The polypeptide later folds into an active protein and performs its functions in the cell
Explanation:
Answer:
<em>B: The drug is a small charged molecule</em>
Explanation:
Substances can passively diffuse in and out of the cell via the cell membrane in two ways;
- Simple diffusion
- Facilitated diffusion
The cell membrane allows small molecules or ions to freely diffuse across it in response to concentration difference between the inner and outer parts of the cell membrane. This is known as simple diffusion.
In facilitated diffusion, special proteins in the cell membrane, known as channel/carrier proteins binds with molecules and facilitates their diffusion across the cell membrane by carrying them through special channels in the membrane.
Hence, to support the alternative hypothesis that the new drug will exhibit simple diffusion across the plasma membrane, the drug should be a small charged molecule.
<em>Correct option: B</em>
Answer:
Explanation:
The tricuspid valve separates the right atrium from the right ventricle carrying deoxygenated blood from right atrium to right ventricle
The mitral/bicuspid valve separates the left atrium from the left ventricle carrying oxygenated blood from left atrium to left ventricle
Pulmonary semilunar valves separates the right ventricle from the pulmonary artery preventing bachelor of blood.
Aortic semilunar valves separates the left ventricle from the aorta preventing backflow of blood
Water escapes from the pores in plant leaves because of evaporation. This water is what keeps the vacuoles in the cells full and shaped, so the vacuoles are like deflating water balloons
The answer to this question would be: prostate glands
The term upper end is a bit ambiguous and it should be better to call it the proximal end of the urethra. The upper ends of the urethra, near the bladder, there is an organ called prostate. The prostate is a gland that only found in males as its function was to produce seminal fluid, make it a bit alkali.
