Why do large organisms require a transport system?​

Biology
2 answers:
Anon25 [30]3 years ago
3 0

Answer:

Larger animals have a lower surface area to volume ratio. This means they need transport systems like our circulatory system and exchange surfaces like our lungs or fish gills. In single-celled organisms such as protists, and small multicellular organisms, essential molecules will move to where they're needed by diffusion.

Answer:

As the size of an organism increases, its surface area to volume ratio decreases. ... Large multicellular organisms therefore cannot rely on diffusion alone to supply their cells with substances such as food and oxygen and to remove waste products. Large multicellular organisms require specialised transport systems.

Select all that apply: Which of the following affect(s) the half-life of a radioactive substance?
frutty [35]

Answer:

The correct answer is option A, the type of isotope

Explanation:

The half life of a radioactive substance is a constant value and thus it is not affected by the temperature, catalyst or mass of the substance.  Basically it is the time taken by a radioactive substance to reduce its mass by half of its actual value. Radioactive decay takes place only when the atomic nucleus becomes unstable and thus the isotope type is the only factor which affects the radioactive decay of any element.

Answer:

The correct answer is glands.

Explanation:

It is known that brain monitors movement, therefore, one can definitely correlate movement of muscles with the brain that comprises the role of sensory and motor neurons. When a stimulus is obtained by the sensory organs, it is transmitted by the sensory neuron to the brain and from their information is further conducted to the effector organs like muscles by the motor neuron. The glands are the group of cells, which takes part in the secretions when instigated by any particular hormone.
