They can produce 3 types of gametes; gggg, ggtt and tttt in the ratio of 1:2:1. As shown in the table attached, the tetraploid parents produce diploid gametes that combine to form genetically varied offspring.
The genotypes may differ from that of the genotype depending on the interaction of the dominant, recessive and codominant alleles.
The answer to the question is 25%
Answer:
Cohesion is an attractive force between same kind of molecules while adhesive force exists between different kinds of molecules. When water moves inside vascular tissue they contain cell sap. It is these two forces which keep materials in cells and water can easily move them to different parts where they are necessary.
Answer:
The flow chart for the cortisol steroid hormone is as follows:
1. Cortisol passes through the plasma membrane into the cytoplasm.
2. Cortisol receptor complex form in the cytoplasm.
3. Cortisol receptor complex enter the nucleus where it binds to gene.
4. Cortisol receptor complex acts as transcription factor.
5. The tranacribed mRNA is translated into specific protein.
Explanation:
Cortisol is small which is hydrophobic steroid hormone which has the ability to move through the plasma membrane of the cells. In the target cells the cortisol binds with the intracellular receptor protein of the cytoplasm which further forms a hormone receptor complex. The hormone receptor complex further moves into the nucleus ad hence acts as a transcription factor which gets bind to the specific gene and thus, activates the transcription into mRNA. The mRNA which is generated subsequently translated into some specific proteins. Proteins which has been produced with response to the cortisol signal function to the stress response.
Answer:
D) habitat isolation
Explanation:
Based on the information provided within the question it can be said that the main factor that keeps the two populations separate would be habitat isolation. This occurs when the different unique characteristics or preferences of the population's habitats prevent them from mating with those with different habitat preferences, thus maintaining them separate.
