This movement from a high concentration area to a low concentration are is called Active transport.

<h3>Active Transport</h3>

Active transport by definition is a process that is characterized by the movement of molecules against a concentration gradient. Additionally, this process requires energy.

As in the question above, glucose molecules have to be moved across the gut lumen of higher glucose concentration to the intestinal cells of relatively low level of glucose.

Blood is transported throughout the body through both arteries and veins, but a significant difference between the two is the pr
Dvinal [7]

Answer:

A. Blood would leak backwards through the damaged valves due to gravity, causing lower leg swelling.

Explanation:

The passage of blood is always in a single direction in the vein due to the presence of valves in the veins.

Any kind of vein injury or vein rupture, causes the valves in the veins to not function in an appropriate manner. The injury might result in inappropriate opening and closing of these valves. The inappropriate functioning of the valves causes the blood to flow backwards. This will eventually lead to blood pooling and putting more pressure on the lower leg veins. hence, there would be swelling in the lower legs.

If starch and cellulose are both polymers of glucose, how come people can digest starch but not cellulose?
Oksi-84 [34.3K]

Explanation:

Cellulose is a structural component of the plant cell wall. It is a polysaccharide consisting of a long linear chain of multiple β - 1, 4 linked glucose units.

Cellulose is difficult for most animals to digest except herbivores because they lack the ability or enzyme to digest cellulose. This enzyme needed is the cellulase which cleave to its β - 1,4 glycosidic bond and hydrolysis it into its constituent molecules (glucose).

Which of the following statements regarding secretory protein translocation is NOT true? Hydropathy profiles are used to computa
miss Akunina [59]

Incorrect statement is: Type II membrane proteins have a signal sequence targeting them to the ER as well as a signal anchor sequence.

Signal peptide or signal sequence is a sequence of amino acids that gets recognized by signal recognition particle (SRP). This sequence is involved in cotranslational translocation into ER, where the protein should be folded. A stop-transfer sequence signals that translation of the protein should continue in the cytosol (not in ER). A signal anchor sequence signals the insertion of protein into the ER membrane.

A wolf's diploid number of chromosomes is 78. How would the number of chromosomes in the wolf's body cells compare to the number
dimulka [17.4K]

Answer: The number of chromosomes in the wolf's body cells is 78 while the gametes has 39

Explanation:

Since each body cell under only mitosis to yield two daughter cells with equal number of chromosome as the parent cell (i.e diploid number, 2n) while sex cells undergo meiosis to yield four daughter cells with half the number of chromosomes as the parent cell (i.e haploid number, n); thus, the wolf's body cells has 78 chromosomes while the gametes has 39 chromosomes.
