Answer:
The blood type matching is a way too broad way to prosecute a suspect since there are about 8 universal blood groups in total. I would demand a DNA test.
Explanation:
Answer: A) sporopollenins
Explanation: Sporopollenin is one of the most chemically inert biological polymers. They contain mainly long chain fatty acids, phenylpropanoids, phenolics and traces of carotenoids. They make up the outer wall of pollen grains, spores and many microorganisms.
Yes and no. Everyone's heart works the same way, is made of the same type of tissue and is located in the same part of the body. However, there are people with diseases who have hearts that are in worse condition and may look different. For example, people with coronary artery disease experience plaque build up in their coronary arteries, which causes a reduction of blood flow to the heart, and in order to treat this they may get a bypass surgery in which another blood vessel from somewhere else in the body, would be used to bypass the blocked blood vessel. In this case the anatomy of that person's heart would be slightly different.
An allele is a variation of a gene that can be expressed as a phenotype.
Explanation:
Genes are the specific sequences of DNA that code for a particular protein in organisms. When the fertilization occurs each parent contributes one chromosome which is homologous this means that both will have genes on the particular loci. The alleles of the particular genes will come together to express the trait.
Allele is an entity of gene which determines how the gene will express the particular trait like tall, short, round, wrinkle etc. It can be said that allele determines the phenotypic trait of a particular gene.
Answer:
The temperatures are so cold that there is a layer of permanently frozen ground below the surface, called permafrost. This permafrost is a defining characteristic of the tundra biome. Mosses, sedges, and lichens are common, while few trees grow in the tundra.
