For an ecological study, you monitor herbivore-plant interactions in a rainforest and notice that mammalian herbivores avoid the

leaves of a particular species of plant. However, a number of tiny herbivorous insect generalists that feed by piercing individual plant cells with their mouthparts appear capable of completing their entire life cycle feeding on this same species. You hypothesize that in this species the chemical defenses are: stored in the vacuole in an inactive form and are activated by enzymes in the cytoplasm. stored in the cytoplasm of epidermal leaf cells. nonexistent. contained in a latex stored in vascular canals.

Contained in a latex stored in vascular canals.

Answer: Option 3.

<u>Explanation:</u>

Plant-herbivore interactions shape network elements across marine, freshwater, and earthly territories. From amphipods to elephants and from green growth to trees, plant-herbivore connections are the essential connection producing creature biomass (and human social orders) from minor daylight.

Herbivory is an interaction in which a plant or portions of the plant are consumed by an animal. Even insects and animals that eat seeds are considered herbivores.

There are no options to choose from and this makes it hard to answer the question. I hope my answer is correct and comes to your help. The reason that the new recruit fainted was that he did not use muscular compression to return the blood to the heart and thus his brain became devoid of oxygenated blood, resulting in the new recruit getting fainted.

Answer:

c. 1:4:6:4:1

Explanation:

The term quantitative heritability refers to the transmission of a phenotypic trait in which expression depends on the additive effect of a series of genes.  

Polygenic heritability occurs when a trait results from the interaction of more than one gene. And these genes can also have more than two alleles. The action of many genes and alleles can cause many different combinations that are the reason for genotypic graduation.  

Quantitative traits are those that can be measure, such as longitude, weight, eggs laid per female, among others. In the exposed example, the measurable trait is the dog´s friendliness. These characters do not group individuals by any precise and clear categories. Instead, they group individuals in many different categories that depend on how the genes were intercrossed and distributed during meiosis. The result depends on the magnitude in which each allele contributes to the final phenotype and genotype. When they interact, they create a gradation in phenotypes, according to the level of contribution.  

In the exposed example, each dominant allele contributes with a higher level of friendliness.    

  • aabb → 0 = Unfriendly/Loner (although not aggressive);
  • Aabb, aaBb → 1 = Somewhat friendly/shy;
  • AAbb, AaBb, aaBB → 2 = Friendly;
  • AABb, aABB → 3 = Very friendly;
  • AABB → 4 = Maximally friendly.

Cross: between two dihybrid friendly dogs

Parentals) AaBb    x    AaBb

Gametes) AB, Ab, aB, ab

                AB, Ab, aB, ab

Punnett square)   AB       Ab       aB       ab

                   AB   AABB   AABb  AaBB  AaBb

                    Ab   AABb    AAbb  AaBb  Aabb

                    aB   AaBB    AaBb   aaBB   aaBb

                    ab    AaBb    Aabb   aaBb   aabb

F1) 1/16 AABB ⇒ 4 = Maximally friendly

    4/16 AABb + AaBB ⇒ 3 = Very friendly

    6/16 AAbb + AaBb + aaBB ⇒ 2 = Friendly

    4/16 Aabb + aaBb ⇒ 1 = Somewhat friendly/shy

    1/16 aabb ⇒ 0 = Unfriendly/Loner

The Phenotypic ratio is 1:4:6:4:1
