Answer:
F (pp) = 0.04
F (Pp) = 0.32
F (PP) = 0.64
Explanation:
Studying population genetics, we used the Hardy-Weinberg equilibrium model. In the case of snails, the H-W principle predicts that the total number of cases in the population should follow the following equation: PP + 2.Pp + pp = 200.
If a population has 200 snails and 8 are affected by a recessive condition, we have 4% affected, or 0.04.
This means that 0.04 corresponds to p², and p corresponds to 0.2.
Therefore, P is equal to 0.8 because p + P = 1.
Knowing the allele frequencies, we go to the frequency of the genotypes.
F (pp) = p² = 0.04 = 8 snails
F (Pp) = 2.Pp = 0.32 = 64 snails
F (PP) = P² = 0.64 = 128 snails
Answer:
B. When Alfred Wegener propose the idea of continental drift
Explanation:
The first true explanation came from Alfred Wegener, who proposed the Plate Tectonic Theory. This theory stated, in a nutshell, that the continents different pieces that collided together at faults.
Technically, explorers found out this way back. If you consider this the answer choice, then C is your best answer.
Answer:
evaporation
Explanation:
the sun help evaporate the water into the clouds ^^
The behavior shown by ants working together, raise and feed offspring in an anthill is called Eusociality.
This behavior is characterized by these 4 characteristics:
- Adults live in groups
- Look after juvenile members
- Reproductive division of labor
- Overlap of generations
Ants are the biggest example of eusocial insects. Other than ants, bees, wasps and termites show eusocial behavior. This behavior helps members of a team to perform equally.
Light microscopy allows microscopist to view dynamic processes in living cells because both live and dead specimens can be viewed. Electron microscopes cannot for the view of living specimens because they use electrons that are destructive to cell. On the other hand, light microscopes use visible light and magnifying lenses to examine specimens.
