Heterozygous Red- Rr
Homozygous Red-- RR
Homozygous white-- rr
Monohybrid cross- Rr
Recessive allele- homozygous white i.e rr
Explanation:
Heterozygous have 2 different alleles of a gene as both Red and white alleles are present in the example Rr.
Homozygous: If the 2 alleles at a locus is same then they are homozygous, it can be dominant as RR or recessive as rr.
Recessive gene are the ones that can be masked by the dominant genes as red is dominant on white.
Monohybrid cross is the result of cross between the individual having either homologous dominant or recessive genes or genotype. The result is generally masking the recessive allele resulting in dominant phenotypic trait but the genotype changes.
From the example given in question:
A cross between dominant red as RR
and a cross between recessive white as rr
The punnet square shows:
r r
R Rr Rr
R Rr Rr
it can be seen that all progeny are red but genotype changed to heterozygous red as Rr
The pancreatic juice is secreted by the pancreas. This pancreatic juice is secreted into the first part of the small intestine known as the duodenum. This pancreatic juice is rich in various enzymes that help in the digestion of various food components (carbohydrates, fats, and proteins). Besides being rich in enzymes, it is also rich in bicarbonate content. The bicarbonate works to neutralize the acidic chyme. This helps the enzymes to function and carry out digestion properly. If the pancreas fails to produce bicarbonate, then the function of enzymes will be altered, and the acidic chyme (coming from the stomach) will damage the small intestine walls.
Answer:
Epiphyseal plate
Explanation:
The growth plate is a thin layer of cartilage that lies between the epiphyses and metaphyses, and is where the growth of long bones takes place.
D. Asteroids vary greatly in size and are mostly made up stone, iron and nickel
