The fertilized cell that results is referred to as a zygote. A zygote is diploid cell, which means that it has twice the number of chromosomes as a gamete
Answer: The change in the structure of the genes or change in the DNA sequence is called mutation. The mutations are of different types that are deletion, rearrangement, insertion and others.
Explanation:
Mutation in which the one to several nucleotides get changed at a point is called point mutation. The point mutation can be in the form of deletion, substitution, and insertion. Deletion will involve the removal of nucleotide that involves the change in the sequence of DNA. When the nucleotide is added to the genome it is called insertion. In deletion and insertion the whole sequence of nucleotides from the point of mutation get displaced this affect the codons in the amino acid sequence which is responsible for protein synthesis so the functioning of the body may get affected by such mutations.
In the case of substitution the new nucleotides are added to the DNA sequence and the one which was already present at that place is removed. So, only one amino acid in the sequence will change so the polypeptide structure will not be affected.
True
Explanation:
The water molecules move from areas of high concentration to areas of low concentration to make an equivalent between the two.
I hope this helps at least a little :D
The question is about a test cross. Definition of a test cross: Generally a cross involving a homozygous recessive individual. When a single trait is being studies, a test cross is a cross between an individual with the dominant phenotype but of unknown genotype (homozygous or heterozygous) with a homozygous recessive individual. If the unknown is heterozygous, then approximately 50% of the offspring should display the recessive phenotype. If the individual is homozygous all the progeny will have the dominant phenotype. James' suggestion to use show the result of the two possible crosses with a Punnet square is a great suggestion.
Answer:
oceanography
environmental science
Explanation:
Oceanographers who have an all-around study of the oceans ( including marine science, geology, plate tectonics, ocean current circulation) are well suited to ascertain how best to harness tide energy to produce power. On the other hand, environmental scientists will ensure that during this process, the environmental impact of the project is well understood to protect the marine environment. An environmental scientist will, for example, ensure the protection of turtle breeding sites on the shores.
Hope this helps
