stellarik [79]

Complete question:

___BLANK___ system contains glands that secrete hormones into the bloodstream, whereas the ___BLANCK__system secretes substances through ducts.

Answer:

The ENDOCRINE system contains glands that secrete hormones into the bloodstream, whereas the EXOCRINE system secretes substances through ducts.

Explanation:

Those tissues that produce hormones might be classified as:

  1. endocrine glands (produce hormones exclusively),
  2. exocrine glands (produce hormones and other secretions),
  3. non-glandular tissues that secrete hormones but are not glands.
  • Endocrine organs, also known as ductless glands or endocrine glands, release their secretion directly to the bloodstream. Blood transport hormones to target cells, tissues, and organs, where they stimulate a change in metabolic activities
  • Exocrine glands release their secretions to a duct of different tissues where they act, such as the internal or external surface of cutaneous tissues, stomach mucose, or pancreatic ducts.

liq [111]

Answer:

phototropism

Explanation:

Phototropism is the phenomenon that is causing the bean seedling to bend as shown.

Phototropism is known to be the growth of a plant or an organism in response to a light stimulus. This means that plants or organisms grow in the direction of the light. From the image shown, we will discover that the bean seedling is bending towards the direction of the sunlight.

This phenomenon usually occur in plants but it can also occur in organisms in fungi.

When the plants grow towards the direction of sunlight, it is known as positive phototropism while when the plants move away from the direction of sunlight, it is known as negative phototropism (skototropism).

Contractions per M
Andreyy89

To make Paramecium Contractile vacuole concentration graph useful the salt concentrations descriptions should replaced with actual values.

Thus, option "A" is correct.

What is Paramecium Contractile vacuole

"It is a sub-cellular structure (organelle) involved in osmoregulation."

<h3>What is a graph?</h3>

"A diagram (such as a series of one or more points, lines, line segments, curves, or areas) that represents the variation of a variable in comparison with that of one or more other variables."

<h3>What does the graph in the given question depict?</h3>

It shows that the Paramecium Contractile Vacuole concentration per minute decreases as salt concentration increases.

But the concentration of salt is not mention in quantity so its not clear what are the lowest and highest concentration affecting Paramecium Contractile Vacuole.

Hence, the Paramecium Contractile Vacuole concentration graph can be more useful if the actual values of salt concentration will be mentioned.
