Active transport is the process by which dissolved molecules move across a cell membrane from a lower to a higher concentration. In active transport, particles move against the concentration gradient - and therefore require an input of energy from the cell.
It will increase (A).
When the distance between two masses becomes lower, the gravitational pull by them on each other will increase.
The lysosomes are the “garbage disposal” of animal cells , the same process takes place in plant cells in its vacuoles
The Principle of <u>segregation</u> states that the 2 alleles present at each gene locus separate from one another during gamete formation and remain distinct.
What is principle of segregation?
According to the principle of segregation theory, every human has two alleles for each specific feature and functions, and these alleles separate throughout the development of gametes. In other words, in everycase, each gamete contains a single allele.
Therefore, The Principle of <u>segregation</u> states that the 2 alleles present at each gene locus separate from one another during gamete formation and remain distinct.

Answer and Explanation:
Corals are translucid or white, but they look brightly colored because they host symbionts with colorful photosynthetic pigments
. They can host different organisms that live on and among them, giving place to an amazing ecosystem.
One of these organisms is the photosynthetic unicellular microalgae, called zooxanteles, that are colorful and provide nutrients to the coral.
Corals provide shelter and protection to the algae, while algae provide nitrogenated nutrients, sugars, and color to the corals. Algae can store nitrogen in their tissues as nitrogen-rich crystals, which are constantly provided to corals.
This symbiotic relation allows corals to grow in different environments that are poor in nitrogen or other nutrients, such as the tropical clear waters.
When changes in radiation, temperature, or salinity in water occur, corals react to these changes losing these algae and becoming translucid again.
