Answer:

b. thick wall.

Explanation:

Endospore is a structure formed by some bacteria, that help them survive unfavourable conditions (e.g. lack of nutrients). This survival strategy of some bacteria (usually Gram+ bacteria) help them stay dormant for a while, until stressful conditions stop. A thick wall composed of many layers (exosporium, spore coat, spore cortex, core wall) of the endospore is what provides resistance to different stressful chemical and physical factors such as UV radiation, temperature, chemical damage etc.

Which environment is most likely to be characterized by dry scrub with frequent fires?

Katyanochek1 [597]

Environments likely to be characterized by the presence of dry scrubs and frequent wildfires are those that lack the presence of rain and suffer high sunlight hours.

When referring to the terrestrial biomes that meet the characteristics described, we can include:

Temperate grasslands
Cold deserts

The temperate grassland/cold desert biomes have:

cold and dry winters
hot, dry summers
Extended sunlight hours

This biome is very dry, and the harsh weather makes it difficult for plants to grow, leading to their dry scrub characteristic. This biome also experiences frequent wildfires due to the intense sunlight and lack of rain to which it is exposed.

lyudmila [28]

Answer:

More info given below.

Explanation:

This attraction occurs as a result of static charge. You see an atom is referred to as the smallest particle of a substance; and when an atom gains or looses electrons it becomes unstable creating a difference in potential. However in this case rubbing induces friction which induces heat. This heat excites the atom to loose electrons creating a negative charge on the silk and a converse positive charge on the pencil.
