Answer:

Explanation:

Active transport is the movement of molecules or substance from a region of lower concentration to a region of higher concentration across a cell membrane against the concentration gradient.

Active transport requires cellular energy and are of two types:

primary active transport that uses adenosine triphosphate (ATP), and secondary active transport that uses an electrochemical gradient.

Active transport helps in the uptake of glucose in the intestines.

Cotransport or secondary active transport is the movement of molecules across a membrane it uses electrochemical potential difference that is created by pumping ions in or out of the cell.

Cotransport helps in the transport of glucose across the cell membrane.

The tensor fasciae latae stabilizes the hip joint and the __________ joint.

vladimir2022 [97]

Answer:

Knee.

Explanation:

Joints may be defined as the articulation by which the bones meet together and constitute the skeletal system. These joints helps in the particular movement of the body.

Tensor fasciae latae muscle is present in the thigh. This muscle is attached with tibia and innervated by the super gluteal nerve that supplies the blood artery. This muscle plays an important role in the stabilization of the knee and the hip joint.

Thus, the correct answer is option (c).

Explain the concept of growth using these terms: differentiate, meristem, elongation, and vascular cambium.

egoroff_w [7]

Answer: Well for one, Differentiate is when a cell matures and is used in a specific function. Meristem is a cell which never differeates and constantly divides so it is a mitotic cell. Elongation is the plant growing length wise therefore the meristem elongates the plant. Vascular cambium is the cambium which starts out in vascular bundles of the plant and then grows to form a ring inside the stem of plants that live for more than year- it causes and increase in thickness of the stem and branches.

Five dialysis bags constructed of membrane, which is permeable to water and impermeable to sucrose, were filled with various con

Gekata [30.6K]

Answer:

The options

A. A

B. B

C. C

D. E

The CORRECT ANSWER IS D.

Explanation:

It is a regular occurrence for dialysis bags or dialysis tubing to be employed in permitting smooth movement of molecules when having to do with a fluid. These bags are normally evaluated to ensure that the client has adequate amount in th bag so as to be able to achieve the goal at hand.

If we have five dialysis bags being formed from a semi-permeable membrane which is impermeable to sucrose, they may be saturated with different concentrations of the sucrose with each of these bags being positioned in different beakers that have an initial amount of 0.6 M of a sucrose solution.

At ten minute intervals, the bags were massed and the weight was calculated to look for changes in the level of concentration. In this situation, the bag with the lowest initial concentration of sucrose is be the one that has its mass reducing over time and that is E.

The attached image confirms our answer as from the graph, option E shows the lowest initial concentration of sucrose.
