Answer:
RrYy is the genotype that is heterozygous for both seed shape and seed color. The traits here we are discussing are pea plant's seed color and shape.
Explanation:
A dihybrid cross is a cross in which two traits are simultaneously being studied. Here there are two traits under consideration that are seed shape and seed color. The seed shape can be round or wrinkled and seed color can be yellow or green. The round seed allele is dominant over yellow seed allele and the yellow color allele is dominant over green color allele.
As homozygous indicate both alleles of a gene are same in an individual and heterozygous condition indicates that both alleles of a gene in an organism are different.
Therefore the genotype of homozygous pea plants for seed color and seed shape can be RRYY or rryy respectively and genotype of heterozygous genotype will be RrYy respectively.
Hope it helps!
Answer:
A
Explanation:
After being digested carbohydrates are broken down into glucose so there would be a decrease in glucose levels. Glucose is needed for cellular respiration so it would also decrease

Answer:
The correct answer is A- B cells are activated and release antibodies
Explanation:
When an antigen invades a mammals body, specific immune cells engulf and ingest it. Some of the digested pieces are displayed on the cells bodies, the next step will be that B cells are activated and release antibodies.
