Answer: sporophyte, gametophyte, alternation of generation
Explanation:
Alternation of generation is a kind of life cycle seen in plants and algae in which the diploid asexual and haploid sexual stages exist. A sporophyte is multicellular and diploid which is an asexual stage. It produces the haploid spores through meiosis. The haploid spores germinate to produce haploid gametophyte. The gametophyte produces gametes by the process of mitosis.
1. All thriving things need energy in order to defend themselves (escape danger) and perform functions such as growth, maintaining balance, repair, reproduction, movement.
Sorry, I don't completely understand the second one
Answer:
B. Fossil fuels are nonrenewable and may cause pollution.
Explanation:
Fossil fuels are nonrenewable, meaning that they cannot be replenished sustainably. So, eventually, we will run out of them because they cannot be renewed.
Another disadvantage of fossil fuels is that they cause pollution. For example, the gasoline that is used by cars creates significant amounts of pollution every year.
Pollution is created by cars, factories, homes, and everything else that uses fossil fuels.
So, the correct answer is B, fossil fuels are nonrenewable and may cause pollution

The attached picture shows how bacteria gain antibiotic resistance. Firstly, a few individuals attain a
beneficial mutation in their genetic material that accords them the capability to survive in an antibiotic. The
individuals are hence able to survive and
reproduce more than those individuals without the mutation. There is, therefore, a genetic
shift in the population in favor of the resistant genotype. After generations, the
whole population becomes antibiotic resistant.
