B because it takes in nutrients through endocytosis so the membrane opens up and envelopes the nutrients
Answer:
D. Specialist Species
<h2>
What is the advantage for species to be specialists, and how can they survive in the presence of opportunistic/generalist species?</h2>
In the setting of specialized habitats or unique situations, specialized species exist. When those conditions and surroundings change, they must adapt or go extinct, thus they must survive while they still exist.
When compared to generalists, they have the benefit of efficiency, which increases the likelihood of survival and, hence, reproduction within certain settings or situations. The generalists, on the other hand, have the benefit of being able to survive in a larger variety of circumstances and have a higher probability of doing so.
Cactuses, which are plants adapted to dry environments, are an example of specialization. More generalist plant species would typically outcompete cacti in most habitats on Earth, but very few of such species could endure the harsh conditions of a desert.
Extreme environmental conditions, competition for limited resources, and "evolutionary arms races" are some of the pressures that cause specialization. Cheetahs sprint quickly both because their prey moves quickly and because quicker cheetahs will be more effective hunters and more likely to procreate. The advantage of specialization is clear when seen from the standpoint of catching the next meal on a daily basis.
My key argument is that specialization's benefits must always be viewed in the context of the environment that generated the selective pressure that resulted in specialization. Although experts are specialists because they must be, their specializations put them in danger.
The two substances are rock (molten and solid) and metal (solid + liquid).
Layers of the earth from the outside in:
1. crust. hard rock/dirt/ground. Shell
2. mantle. melted rock and stuff. Egg white
3. core. Outer core - liquid. Inner core- solid. Nickle and iron. Yolk
The anther and filament, the anther produces pollen. They are the parts of the male reproductive organ in a flower.
<h3>What are the male parts of the flowers?</h3>
The flower can be considered as the reproductive structure of flowering plants.
The anther and filaments represent the male structures of a flower, which may also contain female structures.
The stamen can be considered as the male reproductive organ because this structure is responsible for producing pollen which contains germinal cells in a flower.
