Animals dont need to breed to survive for themselves, but they do need food, water and shelter
is that whats being asked? this is a bit confusing
According to Esaias, the changes aren’t just dramatic, they’re also kind of scary. The fertility of most flowering plants, including nearly all fruits and vegetables, depends on animal-mediated pollination. As the pollinators move from flower to flower for nectar--a high-energy, sugary enticement—the plants dust them with pollen, which the animals transfer from flower to flower.
Answer:
Results in the evolution of the species: Directional selection
Results in new species: Disruptive selection
Favors traits at the two extremes: Disruptive selection
No increase in diversity: Directional selection
One extreme trait is favored: Directional selection
Diversity decreases: Stabilizing selection
Diversity increases: Disruptive selection
Explanation:
Directional selection which is also known as positive selection is known to be a mode of natural selection. In this type of selection, an extreme phenotype is favored over other phenotypes. This makes the allele frequency to move in the direction of that phenotype and this takes place over time.
Disruptive selection (known to be diversifying selection) talks about the certain changes in the population genetics whereby extreme values of a particular trait are favored over intermediate values. This results in new species.
While Stabilizing selection is a natural selection whereby there is a stabilization of the population mean on the particular value of a non-extreme trait. Here the diversity is decreases.
Answer: A watery substance where cell processes take place.
Explanation: Process of elimination. The 2nd and last answer choices are both immediately wrong because cytoplasm is not a hard/solid substance. And the third answer choice is wrong because the cell membrane’s job is to prevent organelles from leaving the cell, not the cytoplasm. Therefore the answer is A, a watery substance where cell processes take place.
Answer:
B that most multicellular animals don't reproduce asexually
