Which is an example of active transport?

Biology
1 answer:
Tju [1.3M]3 years ago
3 0

Active transport is a type of transport that requires energy to move substances across a membrane. It occurs against a concentration gradient.

  • The use of energy to move waste materials out of a cell is an EXAMPLE of transport active.

  • Active transport occurs against a concentration gradient, whereas passive transport (i.e., diffusion) occurs in favor of a concentration gradient.

  • Active transport can be mediated by membrane proteins that move substances from an area of high concentration to an area of low concentration.

  • This movement (active transport ) usually requires the energy provided by the hydrolysis of ATP.

  • Water molecules move across cellular membranes through membrane protein channels called aquaporins that act in favor of a concentration gradient (passive transport).

Example of structure adaptation for animals would be for giraffe. Their long neck allow them to reach for food high up in the trees. They have adapted to their environment.

Example of reproductive adaptation would be for flowers. The reasons plants have bright colored flowers is so that they can attract insects, birds or even bats which can inadvertently transfer pollen from one plant to another.

Nat2105 [25]

Answer:

the SRY gene.

Explanation:

The SRY gene was found within the minimum region of Y-specific DNA required for male development. Confirmation of its role was found by the analysis of XY female patients with mutations within this gene. A mouse has been an important working model to study the process of mammalian sex determination.

Which is the most accurate statement about the heating curve and energy
Maru [420]

Kinetic Energy, Potential Energy and a Heating Curve. Since Temperature is a measure of "Average Kinetic Energy", any change in temperature is a change in Kinetic Energy. Since temperature does not change during a phase change, the energy that is gained or lost is Potential Energy.
