Calculate the diffusive force (J) experienced by potassium in a cell where the concentration gradient is 35 mM, the membrane wid
kodGreya [7K]

Answer:

Diffusive force J = 9590

Explanation:

From the given information:

Concentration gradient C₁ - C₂ = 35 mM = 35 × 10⁻³ M

membrane width Δ x = 1 cm = 10⁻² m

Solubility S = 1

diffusive area A = 10

Temperature T = 1° C = (273 + 1 )K = 274 K

Using the expression:

\text {diffusive force J}  = \dfrac{C_1-C_2}{\Delta x }\times T \times S \times A

J  = \dfrac{35 \times 10^{-3}}{10^{-2} }\times 274 \times 1 \times 10

J  = 3.5 \times 274 \times 1 \times 10

Diffusive force J = 9590

An experiment is done on three tomato plants over a 50 day period to test the following hypothesis: If either fertilizer or comp
olchik [2.2K]

Pot A that contained no fertilizer or compost will serve as a control in this experiment.

<h3>What is Fertilizer?</h3>

Fertilizer may be defined as any chemical or natural substance which is added to the soil with the intention to enhance the soil productivity.

Pot B contained fertilizer, while pot C contained compost, they will definitely grow more than pot A, but pot A serve as a control for this experiment because it does not contain any added resources into it. Hence, it grows naturally.

Thus, it is well described above.

Elastic fibers are important to muscle tissue since they resist excessive stretching and help muscle fibers spring back to its o
brilliants [131]

Answer:

True

Explanation:

Elastic fibers are composed of elastin, myofibrils and fibrillin. They are distributed <u>separately</u>, and therefore do not form bundles(they actually form a kind of mesh), like collagen fibers.

Elastic fibers are usually thin and long and can stretch up to 1.5x of their total length.

These fibers confer elasticity to the connective tissue. The mesh formed of elastic fibers easily yields to minimal tensions, returning to its original shape as soon as the deforming forces cease.

An example of the action of elastic fibers is when we pull the skin from our hands and release it, the elastic fibers are responsible for quickly returning the skin to its original shape.
