in a population of mustard plants, the gene that determines the height phenotype has two alleles. the allele for tall plants (t) is dominant to the allele for short plants (t). in the same population of plants, the gene for flower color also has two alleles. the allele for white color (w) is dominant to the allele for yellow color (w). a mustard plant that is homozygous dominant for both height and flower color is crossed with a mustard plant that is homozygous recessive for height and heterozygous for flower color. what are the possible genotypes of the offspring of this cross?
These crosses could result in genotypes with homozygous dominant, homozygous recessive, or heterozygous genes.
What is the genotype of this cross's progeny?The genetic makeup of the sex cells or gametes (ova and sperm) that were combined during conception to create an offspring determines its genotype. Each parent contributed one sex cell. Normal sex cells only have one copy of each gene for each characteristic.
How can the genotype of a test cross be determined?By examining the phenotypes of the offspring, the unknown genotype can be identified. If mating the unknown recessive phenotypic individual with the unknown dominant phenotype (PP or Pp genotype) results in solely dominant phenotypes (no recessive), then the unknown individual is homozygous dominant.

which hormone is incorrectly paired with its effect? insulin - increases number of glut transporters in skeletal muscle cells cholecystokinin - stimulates release of bile from gall bladder glucagon - increases blood glucose levels gastrin - stimulates stomach motility secretin - stimulates release of digestive enzymes from pancreas
The hormone which is incorrectly paired with its effect is: secretin - stimulates the release of digestive enzymes from the pancreas.
The correct statement is: While cholecystokinin (CCK) increases the release of digestive enzymes in the pancreas, secretin stimulates the secretion of bicarbonate (HCO3).
A hormone called cholecystokinin (CCK) serves as a component of your digestive tract. Your small intestine releases it (secretes it) during digestion. It is sometimes referred to as pancreozymin. Although its role in the brain and central nervous system is not fully known, cholecystokinin (CCK) is also present there.
Secretin is a hormone that controls the body's water balance and affects the environment of the duodenum by controlling secretions from the liver, and stomach. The S cells of the duodenum, which are found in the digestive glands, generate this peptide hormone.

Why is having large leaves an advantage and a disadvantage? Link your answer to different environmental conditions (extended answer)
Answer:
Large leaves have a large surface area, which would allow them to absorb more sunlight for photosynthesis. At the same time, a large surface area would allow for a large amount of water loss.
But large leaves can cope in hot, wet, tropical climates because they counteract the daytime heat-trapping effect using transpiration – something desert plants cannot do because they cannot afford to lose that much water.
The larger the leaves, the more surface from which moisture can be evaporated. If the environment tends to be dry, the life of the plant can be threatened by losing too much moisture - therefore, the reduction in leaf size.
Explanation:
it's more difficult for them to absorb heat at night, making them more susceptible to cold temperatures.
