Answer:
Option B, He has a homozygous genotype
Explanation:
A dominant allele is one which will overshadow the expression of recessive allele. Thus, when a dominant allele and recessive allele appears together in the genotype of offspring , only the trait associated with the dominant allele is expressed. Therefore , if a recessive allele trait is to be expressed , the offspring must have both the recessive allele
Let us see case here
A. Allele for attached earlobes is recessive (e)
B. Allele for detached earlobes is dominant (E)
If offspring has EE genotype, then he/she would have detached earlobes
If offspring has Ee genotype, then also he/she would have detached earlobes as in heterogyzous genotype traits of dominant alleles are expressed.
If offspring has ee genotype, then only he/she would have attached earlobes
Genotype ee is a homozygous recessive genotype

Answer: The cycling of water during this time produces consistent temperatures at each depth.
Explanation:
A life cycle is a series of stages that occur in the life of the organism. The life cycle includes the stages like birth, maturation, adulthood, reproduction. The life cycle varies from organism to organism. The sexually reproducing and complex organisms exhibit multiple stages in their life cycle.
The life cycle of living beings depends upon the season. If the season is unfavorable for survival and reproduction of the organisms, they migrate to locations far away from their native habitats. Living beings are also adapted to survive in the changing seasons.
The cycling of water during this time produces consistent temperatures at each depth. is the correct option. This is because of the fact that seasonal change will affect the lake temperature which is likely to make the environment suitable for the reproduction process of marine organisms. Hence, will help the marine organisms completing their life cycles.
.......is secreted into the bloodstream, whereas _____ is secreted into mucus such as gastrointestinal fluid, colostrum, saliva, tears, and sweat:
a. Monomeric IgM; pentameris IgM
b. Monomeric IgA; dimeric IgA
c. Monomeric IgA; dimeric IgM
d. Dimeric IgA; monomeric IgA
Answer:
b. Monomeric IgA; dimeric IgA
Explanation:
IgA is a class of antibodies that are found mainly in body secretions. In sweat, tears, saliva, mucus, breast milk, and gastrointestinal secretions, IgA is secreted as a monomeric antibody. Smaller quantities of this class of antibodies are also present in blood and lymph. However, IgA is present in a dimeric form in the bloodstream. It makes up 10–15% of all antibodies in the blood. The main function of this class of antibodies is to give localized protection of mucous membranes against bacteria and viruses.
