Answer:

Alleles: allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Alleles are called diploid in humans.

Dominant: In genetics, dominance is the phenomenon of one variant of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome.

Heterozygous: Zygosity is the degree to which both copies of a chromosome or gene have the same genetic sequence.

Homozygous: Homozygous is a word that refers to a particular gene that has identical alleles on both homologous chromosomes

Recessive: Recessive: A condition that appears only in individuals who have received two copies of a mutant gene.

PLEASE HELP!! Identify a specific environmental factor that will cause a response to living things, and describe how this factor
jasenka [17]

Answer:

A specific environmental factor that will cause a response to living things will be light from the sun.

Explanation:

An enhanced amount of light from Sun will cause the plants to have enhanced photosynthesis. Photosynthesis can be described as a process by which plants use light energy from the sun to convert carbon dioxide and water into sugar (food) and oxygen.

In animals, enhanced amount of light from the sun will cause sweating and vasodilation.

The process of photosynthesis won't occur in animals and the process of sweating won't occur in plants.

2. There are two different types of rainforests, and they include both temperate and tropical. The tropical rainforests are the ones that are most commonly found around the world.

3. A fifth of our fresh water is found in tropical rainforests, the Amazon Basin to be exact.

5. Rainforests are threatened each and every day, especially by practices such as agriculture, ranching, logging and mining.

Hope this helps!
