The answer is B. The first cross between the black-eyed mendelian and an orange-eyed mendelian resulted in all of them having black eyes. This means that black-eyed is the dominant trait in the species. That means if a phenotype is orange-eyed then it is homozygous recessive (bb). There will be no black-eyed since all of them are recessive.
Answer:
The diversity of species
Explanation:
Darwin investigated the diversity of species by observing the physical differences between them. He concluded that all the species came from the same ancestor in common. And that the evolution is given by natural selection (or adaptation to the environment). Only specimens more adapted to the environment could survive, reproduce and pass their genetic traits to their offspring.
For example, the long neck of the giraffes is due to the fact that only the highest ones reached the leaves of the trees for food and with that they managed to survive.
Microbes cause tissue damage to their host cell or body in different ways.
1. Microbes can release toxins that can damage the cells and tissues of the host.
2. Microbes can release enzymes that can breakdown the cells and tissues of the host.
3. Microbes can activate certain responses in the host that can make the latter destroy its own tissues. Usually, the immune response of the host cell is disturbed, making the immune system attack the cells of the host itself.
