8 0

The tissue below the epidermis of a leaf stalk is Collenchyma.
Collenchyma tissue is composed by elongated living cells of uneven primary thick walls, which possess hemicellulose, cellulose, and pectic materials. It provides support, structure, mechanical strength, and flexibility to the petiole, leaf veins, and stem of young plants, allowing for easy bending without breakage.

What is the approximate astronomical distance between the sun and proxima centauri the closest star to the sun ?

LiRa [457]

It is about 4.22 light-years from Earth and is the closest star other than the sun. Alpha Centauri A and B orbit a common center of gravity every 80 years. The average distance between them is about 11 astronomical units (AU) — about the same distance as the sun is to Uranus.

QveST [7]

Answer:

The correct option is a decomposers

Explanation:

Decomposers can be described as organisms which feed on dead and decaying material. These organisms break down molecules and use them as a source of food. Among the options mentioned, the option of decomposers is the only one which is applicable to fungus like protists and is unique to it. On the other hand, Plant like protists make their own food by the process of photosynthesis. Hence, option A is correct.

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.
