haploid
Explanation:
Sexual reproduction involves the production of haploid gametes by meiosis, followed by fertilization and the formation of a diploid zygote.
The statement which is false about the intergumentary system is option D. "Keratin is the pigment responsible for skin color."
Even though the skin color of human beings is affected y different substances, the pigment melanin is responsible for it. Melanin is produced within the skin in cells known as melanocytes and it determines of the skin color of darker-skinned humans.
For instance, the skin color of those who have light skin is determined primary by the bluish-white connective tissue placed beneath the dermis and by the hemoglobin which circulates in the veins of the dermis.
The presented picture shows 4 trophic levels of the ecosystem.
The first level is made out of primary producers, plants. The second level is made out of herbivores that feed on the plants. The third level is made out of predators that eat herbivores.
The fourth trophic level is made out carnivores that eat other carnivores.
In our case, the only organism belonging to the fourth trophic level is the wolf.
