Answer:
Glucose entering the intestines from the villus.This is by active transport.The latter is defined as the movement of molecules and solutes from the region of lower concentration to the region of higher concentration against the concentration gradient.
Explanation:
All the above options depends on the diffusion gradients from one higher region to another.e.g oxygen passing from high concentration from outside to lower concentration in blood stream,like wise Co2 from higher concentration from inside to outside,with passive diffusion lipids and water enter the small intestine(note amino acid and glucose,and fructose are different).
Active transport( through sodium dependent transporter) transports glucose to the intestine from the villus.This is movements against concentration gradient because,glucose molecule are concentrated in intestine,and needed by the cells, in the body.Therefore they must be transported as a fast rate inn the blood .
However the absorption by the villi is very slow,therefore active transport is needed to move these against the concentration gradient into the intestine.And finally the blood.
If this were to be moved by passive diffusion,the high concentration in the intestine will force this back into the villi
Therefore extra energy is needed by active transport for the glucose molecules to enter the intestine from the villus.
Answer:
means "approximately", "about", or "around", such as "~30 minutes before", meaning "approximately 30 minutes before".
The bacterium, which is able to survive in both aerobic as well as anaerobic conditions are known as facultative anaerobes.
The facultative anaerobes are the organism, which can use oxygen for the synthesis of the ATP (adenosine triphosphate) molecule, but in the condition, where the oxygen is less or absent, they shift to fermentation or anaerobic respiration.
Hence, the correct answer is facultative anaerobes.
A sequence of dna that codes for a specific, detectable product, such as a protein or rna is called a gene and is therefore denoted as option B in this scenario.
<h3>What is a Gene?</h3>
This is referred as the basic unit of hereditary and is usually passed from the parent to the offspring. it also contains information which helps in the coding of certain substances such as protein.
The gene which comprises of DNA which is referred to as deoxyribonucleic acid ensures that certain types of traits are passed to the offspring thereby resulting in genetic variation. This is a function of the type of cell division known as meiosis which gives rise to four unique daughter cells.
This is therefore the reason why gene was chosen as the most appropriate choice.
