Flowering plants reproduce sexually through a process called pollination. The flowers contain male sex organs called stamens and female sex organs called pistils. The anther is the part of the stamen that contains pollen. This pollen needs to be moved to a part of the pistil called the stigma .
Answer:
The plasma membrane is selectively permeable
Explanation:
hydrophobic molecules and small polar molecules can diffuse through the lipid layer, but ions and large polar molecules cannot. Integral membrane proteins enable ions and large polar molecules to pass through the membrane by passive or active transport.
The stomach normally secretes acid that is essential in the digestive process and this helps in the breaking down of food during digestion. Acidity is responsible for ulcer, dyspepsia, heartburn and the formulation of the ulcer. One way to experiment on how the acid is neutralized is by using vinegar and starch.
Answer:
<em>If all variation among individuals in a population is due to differing genotypes alone, heritability is 100% and the slope of the line used to measure it is 1.</em>
Explanation:
If the genes play no role in the variation among organisms of a species, then the heritability will be zero percent. Hence, if all the variations among individuals of a population occur due to the differences in the genotype, hence the heritability will be 100%. This is because genes are the hereditary molecules and the genotype of an organism comprises of the different genes present in an organism.
Answer:
The correct answer is e. all of the above
Explanation:
A person can only have two allele of a character, therefore, the genotype of a male parent can be IBIB or IBi and the genotype of female parent can be IAIA or IAi. Therefore during gamete formation, all allele will segregate and assort independently.
So all the possible combinations are possible that are IAIB, IAi, IBi or ii because all the allele can be present in the two parents in which one have A blood group and another have B blood group.
Therefore their children could have A, B, AB, or O blood group so the correct answer is e. all of the above.
