Answer:
4
Explanation:
According to Mendel's law of purity of gametes, each gamete contains single allele for a gene. The alleles of a gene segregate during gamete formation and each gamete has one allele for a gene irrespective of the total number of alleles for a gene.
If the gene for skin color in a fish species has four alleles, an individuals fish would have only two alleles which in turn would segregate during gamete formation.
Since there are four different alleles of the gene (let's assume a,b,c, and d), total possible gametes produced by this organism will be = 4. A gamete can have one of the total 4 alleles making total 4 types of the gametes each with a or b or c or d allele.
Answer:

Explanation:
The double red program is a program where red blood cells are donated by people . This red blood cells are used for treatment of patients that require red blood cells such as transplant of organs, transplant of tissues, treatment of cancer e.t.c.
Apheresis is a process whereby blood is collected or removed from the body and it undergoes the process of filtration into various components of the blood.
The machine that is used during apheresis collects the human blood and separates it into white blood cells, red blood cells and platelets.
B) Endocrine disruptors mimic hormones that regulate critical biological processes

Positives:
Technology, which brings together tools to promote development, use and information exchange, has as its main objective of making tasks easier and the solving of many problems of mankind. When technology progresses and makes our lives even more convenient, we must stress how beneficial it is to our lives
2. Don't know
3. Decision Matrix Method. Decision matrix techniques are used to define attributes, weigh them, and appropriately sum the weighted attributes to give a relative ranking among design alternatives.
The answer is Silurian period (443 million to 416 million years ago). This was the era when life in the seas and oceans began to conquer land. This is associated with a period of warm climate, rising sea and ocean levels hence giving shallow-water grounds where reefs developed. Plants like bryophyte began to develop including the emergence of terrestrial arthropods
