B. requires flowers.
Sexual reproduction is one type of biological reproduction wherein the genitals of the male and female organisms engage into a sexual activity in order for the sperm cells to fertilize the egg cells of the females.
In the case of most plants, they engage in asexual reproduction. Asexual reproduction happens outside the body system of a cell.
Moreover, this process is extrinsic than its opposite the sexual reproduction which happens in the female reproductive system.
Answer:
You did not write the concept, so i will try to answer in a general way.
Why sometimes we really need to model concepts?
Well, sometimes the things are really complicated, or we just do not have the knowledge or tools to fully understand them.
Here is where the models came to be handy, we can somewhat "simplify" the things, and explain them with models.
For example, the movement of a particle as the wind pushes it can be really complex, so this can only be explained with a model.
Now, once we have a model (supported by theory and experiments) we can start to investigating furthermore in the given subject.
So for example, we could model how a given therapy acts on a given disease, and with that model, we could extrapolate the effects of the therapy in a similar disease (for example, testing how radiotherapy acts on a given tumor in some organ, can give information on how the same therapy can act on other types of tumors)
Concluding, models simplify some concepts, which allow us to understand them and work better with them
Answer: "sexual" ; in the sense that they reproduce "sexually" —and NOT asexually.

It should continue to be restricted. If it is not restricted, there is a chance it will become extinct. This not only has bad consequences for us, it destroys the food web as a trophic level is effectively eliminated.
Hydrosphere
Explanation:
- The dolphin swims in the hydrosphere.
- The hydropshere is the region occupied by water on the earth surface.
- They are the oceans, lakes, rivers, glaciers e.t.c
- The hydrosphere makes up 70% the total surface area on earth.
- Ocean occupies a whooping 95% of all.
- The hydrosphere is able to support aquatic life and this is why the dolphin with its streamlined body swims in this sphere.
