Answer:
Genes
Explanation:
A gene is a hereditary unit that parents pass to their offspring, and they will determine the kind of characteristics the baby will have like will they be short or tall, have blue or brown eyes, will they have blond or black hair. The offspring will get different genes from its parents and it will therefore be genetically unique. Some traits or characteristics may be dominant over others. For example the mother has brown eyes and the father has blue eyes, so in this case eye color has two alleles (an allele is a specific version of a gene, in this case allele for blue eye color and an allele for brown eye color), and now the baby is born with brown eyes, so brown eye color was dominant over the blue eye color so that is the trait that we will see in the baby. The genetic is a lot more complex but this is a more simplified explanation of how offspring express certain traits from their parents.
Water molecules stick to the cell walls of plant's thin veins which helps prevent the water from falling backwards due to gravity.
Answer:
The autosomal trait are present on the autosomes and does not have any influence on the sex of the organism. Two main types of autosomal trait are autosomal dominant and autosomal recessive trait.
a. The trait discussed in the question must be the autosomal dominant trait. As the normal and affected children are produced by the affected parents cross. The appearance of the normal child determines that the trait is dominant.
b. Since both the parent are affected but the normal child has been produced from the cross. The parents must be heterozygotes for the trait, (Aa). Their cross will produce the progeny AA, Aa and Aa (affected) and aa (normal).
Explanation:
A transgenic organism has Gene's of both male & female organisms. The purpose of this is to ensure reproduction of a species.
Answer:
increases the amount of energy in the Earth's budget.
Explanation:
Increase occurs in the amount of sea ice at the north pole leads to increases the amount of energy in the Earth's budget because this sea ice reflects the solar radiation back to space. Sea ice has a bright surface which causes 80 percent of the solar radiation reflected back into space. As sea ice melts in the summer, it exposes the dark ocean surface which leads the ocean to absorbs 90 percent of the sunlight which heat up the oceans, and increase in the temperature occurs causes more melting of ice so increasing sea ice is good for the earth.
