Answer:
The zygote will have 96 chromosomes.
Explanation:
If self-fertilization occurs, and two gametes (each having 48 chromosomes) unite, the zygote will have 96 chromosomes ( or 4 sets)
If it displays the dominant genotype, we can assume that this plant would have a heterozygous (hybrid) genotype, i.e.
With a purebred recessive plant, the geneotypes would be 50% Bb and 50% bb.
With a purebred dominant plant, the genetpyes would be 50% BB and 50% Bb.
With a <span>heterozygous (hybrid) plant, the genotypes would be 25% BB, 50% Bb and 25% bb.</span>
Answer:
Cane toads were introduced intentionally in Australia in 1935 to combat cane beetles in the sugar cane crop fields. These toads exhibit higher feeding capacity. These can feed not only cane beetles but other insects which affecting agricultural yields. They are poisonous in nature, they kill any insect after ingestion. Therefore, they are useful biological insecticide which provides crops resistance against insects.
Answer:
Second-intention healing
Explanation:
There are two types of wound healing. Primary-intention and secondary intention healing. They both occur in four stages namely;Homeostasis,inflammation, proliferation and remodelling
In primary-intention healing, it occurs in wounds with dermal edges that are close together example wounds made by a scapel.
Healing by secondary intention occurs when the sides of the wound are not opposed that is, they are not surgically approximated, therefore healing must occur from the bottom of the wound upwards. That is by granulation, contraction, and epithelialization
50 percent. If you make a Punnett square and put the genotypes Aa and Aa from the two heterozygous parents and combine them, you get the following results: AA, Aa, Aa, and aa. 2 of the four possible genotypes are heterozygous. 2/4=0.5. Fifty percent. Ta-da.
