Answer:
B Binary fission maintains genetic continuity because the daughter cells contain the same number of chromosomes as the parent cell.
Explanation:
Genetic continuity ensures that genetic information is passed from one generation to another in correct way so that the resultant progeny has the complete set of genes required for survival. For example, at the end of mitosis, daughter cells should have the same number of chromosomes as parent cell.
Binary fission is a method of reproduction in some organisms like bacteria. It is an asexual mode of reproduction in which the parent cell splits into daughter cells without the process of fusion with another cell. It still maintains genetic continuity because the daughter cells are identical to the parent cell and thus have same number of chromosomes and type of genes.
I think it’s DNA molecule
Nerve Regulators: Two types of nerves help to control the action of the digestive system. Extrinsic (outside) nerves come to the digestive organs from the unconscious part of the brain or from the spinal cord. They release a chemical called acetylcholine and another called adrenaline
Answer:
Genotype - AaMm
Phenotype - Heterozygous purple stem and fruit with two locules
Explanation:
Given
Trait 1 - Recessive allele for green color stem is represented by a
and dominant allele for purple color stem is represented by A
Trait 2 - Production of two locules in the tomato fruit is a dominant trait and is represented by "M" and production of multiple locules in the tomato fruit is a recessive trait and is represented by "m"
F1 cross is carried between tomato plant with purple stem and fruit with two locules (AAMM) and a tomato plant that have fruit with multiple locules and a green stem (aamm)
The following offspring will be produced
AM AM AM AM
am AaMm AaMm AaMm AaMm
am AaMm AaMm AaMm AaMm
am AaMm AaMm AaMm AaMm
am AaMm AaMm AaMm AaMm
Genotype - AaMm
Phenotype - Heterozygous purple stem and fruit with two locules
