Answer: Food and space
Explanation:
Think of the squirrels and birds. They both reside on trees and they compete for the resources like space and food available on the trees.
The fruits that is available on the tress has competition between the birds and squirrels.
Both of the organism also have competition for the space to live. Though birds are not available at the day time but they come to stay on trees at evening and night.
The squirrels have a better grip to fruits in their hands so that the birds cannot get it from them.
Squirrels also move on the land for the food so that they have less competition on trees for food.
Answer:
lac promoter incorporated into the genome of E. coli, = for the repression of the gene
T7 gene incorporated into the genome of E. coli,+ for the formation of T7 gene
and T7 promoter on the plasmid introduced into E. coli= for the attachment of Polymerase to transcriped RNA from 5 to 3 direction
Explanation:
A. TRUE
These are grouped as the term "gonadotropins" because they affect the gonads.
Answer:
30
Explanation:
The seed of an angiosperm is formed as a result of fertilization (fusion of sperm in pollens and the ova from ovary). According to the question, the cells of the seed which will grow into the plant contains 20 chromosomes. Seeds of angiosperms contain a tissue called ENDOSPERM that forms as a result of the unique DOUBLE FERTILIZATION in angiosperms. It occurs when one haploid sperm cell fuses with two haploid polar nuclei to form a triploid endospermic structure that serves as food for the growing embryo in the seed.
Now based on the above explanation, the diploid plant cell with 20 chromosomes will have 10 chromosomes (half as much) in its gametes as a result of meiosis. This 10 chromosomes in each gamete (sperm and ovum) fuses to form a diploid zygote with 20 chromosomes, while one haploid sperm cell (10 chromosomes) also fuses with two haploid polar nuclei (10 chromosomes each) to form a triploid endosperm with 30 chromosomes i.e. 10+10+10.
Answer:
Oxygen
Explanation:
Sunlight is vital to the production of Photosynthesis in plants, which then produces Oxygen.
