Answer:
A. dihybrid crosses
Explanation:
A dihybrid cross can be defined as a mating experiment between two lines/varieties/organisms that differ in two phenotypic traits. By using pea plants, Mendel performed dihybrid crosses in order to analyze the mode of inheritance of both phenotypic traits at the same time. From these mating experiments, Mendel observed that the inheritance factors (nowadays called genes) sorted independently from one another in the next generation, which is called the principle/law of Independent Assortment.
Answer:
carbohydrates
Explanation:
because they are energy providing foods
Some of the conditions that must be met for a population or an allele to be in Hardy-Weinberg equilibrium are:
1. The population must be very large.
2. There must be no migration and population must be isolated.
3. There must be no mutations.
4. There must be random mating, which means there are no mating preferences.
So, a population will not be at Hardy-Weinberg Equilibrium if it is small, or there are mutations, which is not mentioned, but mutations are expected to occur. Also, although there is a large mountain, skunks can migrate to some other area of a woodland. So, probable mutations and migrations suggest that the population is not at <span>Hardy-Weinberg Equilibrium.</span>
Since you are trying to investigate the possible variables that contribute to reef threats, it is advisable that you do an environmental study between two reefs that have characteristics that are similar or are closely similar. With this, you will be able to identify which is the primary cause of reef threats. Thus the correct answer is B.
Answer:
ATP uses the energy from ATP hydrolysis and moves ions across the membranes.
Explanation:
- The mechanism of transportation of proteins and ions across cell membrane uses the ATPase that consume the energy from ATP hydrolysis and moves the small molecules across the cell membrane.
- The energy is used against a established electric potential or simply the chemical concentration gradient.
- This mechanism of transportation of ions is the example of active transport and a coupled chemical reaction.
