Answer:

Four.

Explanation:

Initially four haploid spores are produced by meiosis. We know that during meiosis pairing between homologous chromosomes occurs and this created genetic difference between the divided cells. Exchange of genetic material doesn't occur during mitosis so mitotically divided cells are similar. Thus when spores divide by mitosis and become eight in number, here will be no new genetic difference.

The complete sentence will be -

A nucleus within an ascus undergoes meiosis, producing four haploid spores, which then undergo mitosis, producing eight haploid ascospores. These haploid ascospores contain a maximum of four different genetic types.

Answer:

Preserving the habitat of an endangered species is important to its protection. Little brown bats live in a wide range of habitats. They live in forests and mountains, and even form colonies in buildings, attics, and other artificial structures that humans could be affecting. Sadly, many bats are under severe threat from increasing human pressure. Habitat loss, climate change, roost destruction, disease, deforestation, guano mining, disturbance and persecution, and increasing numbers of wind farms are all causes of bats declining because of us.

The rock cycle is affected by the biosphere in addition to geological processes. Hypothesize about the role in the rock cycle of
Luda [366]

The rock cycle plays an important role in the process of calcium carbonate formation is that it is built by plankton and corals. Therefore, it is true that the rock cycle is influenced by the biosphere processes as well as the geological processes.

<h3>What is the significance of the rock cycle?</h3>

A rock cycle can be described as the process that leads to the formation of minerals and chemical elements because of the occurrence of natural processes near the oceans and water bodies.

Substances like calcium carbonate (CaCO₃) are one of the influential formations in the rock cycle. The formation of calcium carbonate is highly contributed by the plants and animals to form the plankton as well as the corals on reefs.

Therefore, the significance of the rock cycle has been aforementioned.
