Answer:

Competition happens when a population becomes too large and must compete for food, water, shelter, and other resources. Basically, these limiting factors only happen when a population becomes too big and its environment can no longer support it.

Assuming you mean to type:

 

"In humans, the allele for dimples (D) is dominant to the allele for no dimples (d). at another gene locus, the allele for broad eyebrows (B) is dominant to the allele for broad eyebrows (b)."

 

Man: Heterozygous for both genes means DdBb

Woman: no dimples, and heterozygous for slender eye-brows means ddBb

 

Punnett Square

 

         DB       Db         dB        db

dB   DdBB   DdBb    ddBB    ddBb

dB   DdBB   DdBb    ddBB    ddBb

db    DdBb    Ddbb    ddBb    ddbb   

db    DdBb    Ddbb    ddBb    ddbb   

 

Interpretation: anywhere that has a capital letter has the dominant trait.

Dimples+Broad eyebrows : 6 cases out of 16  (3/8=37.5%)

Dimples+slender eyebrows: 2 cases out of 16  (1/8=12.5%)

No dimples+Broad eyebrows: 6 cases out of 16 (3/8=37.5%)

No dimples+slender eyebrows: 2 cases out of 16 (1/8=12.5%)

PLEEEAAASEEE HEEELLLPPPP!!! I CAN MARK BRAINLIEST! Write a well-explained paragraph for the prompt below. Be sure to explain BOT
belka [17]
It is crucial that we protect, conserve, and support the global population of producers. This claim is supported by the evidence that was discovered in the experiment of the water tank. As seen in the experiment, when the fish were increase, the levels of oxygen were decreased. Then, as soon as more plants (producers) were added to the tank, the oxygen levels increased once again. Theses evidences can be applied on a larger scale of the earth. An analogy could be made between the fish and plants in the tank to the animals, humans, and plants all over the world. As the population of animals and humans continue to grow around the world, more and more trees and plants get cut down. As this continues the oxygen levels will decrease, which can be supported by the evidence in the lab.
