How long will a species be able to survive if the females are able to reproduce but only half can?
Species would survive indefinably in such conditions .
How do microbes become resistant?
Microbes evolve. Those which are better able to survive the drugs that people use to kill them will be more likely to give rise to new generations of microbes. It works exactly the same way as any other form of evolutionary pressure.
What is the process whereby only the fittest organisms survive and are able to reproduce?
natural selection
Organisms with traits well-suited to their environments survive and reproduce at a greater rate than less well adapted organisms in the same environment is called?
Natural Selection. Survival of the fittest. The organisms with the best traits are able to survive and reproduce.
What does biological organization means?
the organisms can effectively survive and reproduce to make sure that its genetic traits are passed on. Those that aren't biologically fit are not able to reproduce effectively and eventually their genes pass out of the gene pool.
What must a spices be able to do in order to survive and reproduce?
A species must be able to find food, shelter, and water in order to survive and reproduce. Until a species is able to meet its essential needs, it is not able to reproduce and survive.
How long will a species be able to survive if the females are able to reproduce but only half can?
Species would survive indefinably in such conditions .
What does it mean to be biologically fit?
To be biologically fit means you have the adoptions to survive and you are able to reproduce offspring that can reproduce lots and lots of babies (offspring)!

Must EVERY memeber of a particular species one kind of organism be able to reproduce in order for the species to survive?
No. It is not necessary for EVERY member of a species to reproduce in order for the species to survive. Consider humans. Some are infertile and can't reproduce, and some choose not to reproduce, yet the human species survives.
Can animals grow in the desert?
Of couse, animals can grow in the desert. They would not be able to survive and reproduce if they did not grow.
What is a imperiled species?
A species that is in danger of becoming extinct. There are low numbers of the animal and they may not be able to reproduce fast enough to survive as a species. Or they may face some environmental factor that is causing them to not reproduce enough to survive.
Can neither...nor be used to combine sentences with two different subjects and verbs like neither are animals able to reproduce nor plants to survive from the heat?
No, the construction "neither...nor" should be used to combine sentences with the same subject and verbs, such as "Neither animals are able to reproduce nor plants are able to survive from the heat."
What term is defined as the tendency of some members of a population to be better able to survive and reproduce and pass their characteristics?
Natural selection.
Must every number of a species to reproduce in other for the the species to survive?
They must be able to reproduce, however a large percentage of the offspring never reach sexual maturity and only a smaller percentage of those will reproduce in many cases.

Natural Selection. Survival of the fittest. The organisms with the best traits are able to survive and reproduce.
