An alleles is dominant is heterozygote when it is
Fittoniya [83]

An allele is dominant and heterzygote (Pp) when a dominant allele (P) is crossed with a recessive allele (p).

Explanation:

A dominant allele is the one with a particular dominant character or phenotype which dominates even though there are other alleles found.  

A heterozygous allele results from two different alleles coding for a gene.

A heterozygous dominant allele (Pp) results from the crossing of a dominant allele (P) with a recessive allele due to complete masking of the recessive allele (p).

For example, when dominant brown eyes are crossed with recessive blue eyes, in a heterozygous dominant allele results in brown eyes and masks the recessive blue eyes.

Differentiate Humoral immunity vs cell mediated immunity
trapecia [35]

Answer:

Cell-mediated immunity develops through a network of interactions that results in defense against microorganisms that survive within phagocytes or other cells. The response is initiated by the recognition of intracellular microorganism antigen by T cells through the histocompatibility complex. In the CD8 response, only the target cell carrying the class I associated antigen can be lysed or induced to apoptosis. In another mechanism of the cellular response, CD4 + Th1 T cells activate, for example, cytokine-infected macrophages such as IFN. When a pathogen resists the effects of activated macrophages, chronic infection may develop.

The hormonal immunity response leads to the destruction of extracellular microorganisms and prevents or decreases the spread of intracellular cells by neutralizing, opsonizing and activating the complement system.

Who uses the oxygen plants release during photosynthesis?
AlladinOne [14]

Answer:

During photosynthesis the oxygen is released into the atmosphere through

All photosynthetic eukaryotic cells contain chloroplasts that use the radiant energy of sunlight to convert carbon dioxide and water into carbohydrates. As a byproduct of photosynthesis, oxygen gas is also released into the atmosphere through tiny openings in the leaves called stomata.
