Answer:
include roots, stems, shoot buds, and leaves; they are not directly involved in sexual reproduction.
Answer:
50%
Explanation:
Both parent's genotype is Bb because they are hairless and alive.
If it has a homozygous dominant genotype (BB), the dog will die in utero.
If it has a heterozygous genotype (Bb), the dog will be hairless but won't die.
If it has a homozygous dominant genotype (bb), the dog will have hair.
The ratio of BB:Bb:bb is 1:2:1 meaning that there is a 50% probability of having a live hairless puppy.

Answer:
It fuses with and becomes part of the plasma membrane.
Explanation:
Exocytosis -
Exocytosis is the process of expelling out the substances from the cell . It also helps in the cell transport and cell signalling process .
In this process a large amount of molecule are released and making it a form of the bulk transport .
In this process , the secretory vesicles are then carried to membrane of the cell and then their contents are secreted into the extracellular environment .
DNA is copied during mitosis and when the two resulting copies of DNA are compared they are found to contain the same order of nucleotides is not the result of mutation in the DNA sequence of an organism.
Explanation:
Mutation is the process
It is caused by certain chemicals called mutagens or by environmental factors.
In mutation the nucleotide get change which eventually changes the protein product.
In mutation purine base gets mutated to purine base and pyrimidine base gets mutated to pyrimidine only.
A single change in nucleotide is called point mutation and the effect occurring because of it is called frame shift mutations.
In S phase there are checkpoints which ensure that DNA replication is accurate and when mitosis follows it equal distribution of DNA takes place between the two daughter cells hence no mutation will takes place.
Answer:
The fusion of two gametes to form a diploid zygote is called SYNGAMY.
Explanation:
During sexual reproduction process, exchange of DNA usually occur and this introduces diversity into the offspring that are produced. One of the ways by which exchange of DNA take place is called syngamy. Syngamy involves the bonding together of two sex cells leading to the formation of cell that has double amount of the chromosomes in the parent cells. The two cells that bond together are called gametes while the diploid cells formed is called zygote. The major function of syngamy is creation of variation; the genotypes in the formed zygote differ from those of the gametes.
