Answer:
Cooperation
Explanation:
Cooperation is a type of behavior evolved by members a species living together in a close-knit society, whereby they all work and act together to ensure the common good of all members. This behavior ensures the survival of the members of the species in any environment.
Cooperation among small birds ensures protection of the members of the group against predators. Also, pack hunting is a form of cooperation among animals of a species to ensure nutrition is provided for all in the group. Se animals also form defensive circles as a form of cooperation to ensure protection of members, especially the weak and young members, against predators.
Vertebrates developed about 550 million years ago. The oldest vertebrate fossils are those of FISH with no jaws. These e<span>arly jawless fish did not have paired fins and their bodies were covered with heavy, bony scaled, but their skeletons were made of cartilage. For the next 50 million years, they were the only vertebrates.</span>
To solve this problem on genetic dominance, we will need a punnet square.
Let's let P represent purple-flowered and p represent white-flowered.
We have one purple flowered plant with the alleles PP, and we have one white flowered plant with the alleles pp. Using a punnet square, we can determine the alleles of the offspring.
<u>P</u> <u>P</u>
p| Pp Pp
p | Pp Pp
As we can tell from our punnet square, all of our offspring will have purple flowers. This is because the purple-flower allele is dominant and the white-flowered allele is recessive.
Since each flower has a dominant and recessive allele, they are heterozygous.
Therefore, the solution to this problem is D.
The bacterium is not susceptible to the penicillin family of antibiotics. it contains no plasmids and relatively little peptidoglycan. Adherence to the intestinal lining by this bacterium is due to its possession of a capsule.
