Which process results in the formation of structure X?
A) mitosis

Answers

The process that leads to the formation of structure X in the diagram would be meiosis.

The diagram is that of the female's reproductive structure showing the uterus, ovary, and fallopian tubes.

The structure marked X is an ovum or egg.

The ovary produces ovum or eggs through a division known as meiosis.  

The ovary is diploid (2n), but gives rise to haploid (n) eggs by meiotic division. Thus, meiosis is referred to as reductional division.

What are the living things that are best adapted to their environment will be more likely to survive

Answers

Answer: They are more likely to survive due to NATURAL SELECTION.

Explanation:

Adaptation of living organisms is the ability of these organisms to use its features which may by structural, physiological or behavioural to reproduce and survive in its environment.

NATURAL SELECTION plays an important role in the adaptation of organisms for survival. This is the process whereby the better fitted or adapted varieties of species in population are selected by environmental pressures. For example, a plant population in a region which had become drier climatically faces a water shortage problem not present previously. Among this plant population are a few individuals with a better developed root system and a thicker layer of cuticle. These individuals have a better chance of survival now because they can obtain a greater share of the limited water supply and reduce water loss from their surface more efficiently.

In the above example, the change to drier climate imposed an environmental pressure on the plant population. This affected the survival and reproduction of the individuals in the plant population in such a way that eventually a variety better adapted to the drier climate dominates the population.

After a forest fire, which type of organisms will begin secondary succession?
small shrubs
mature oaks
evergreens
wildflowers

Answers

After a fire, species start to recolonize an area, beginning the secondary succession process. The first species to colonize are usually fast growing herbaceous plants, such as conifers or ferns.

Small shrubs are the kind of organisms that start secondary succession after a forest fire. The correct option is A.

Thus, the term "secondary succession" describes the ecological recovery process that follows a disruption like a fire. Small shrubs have developed survival strategies that enable them to swiftly colonize damaged environments.

They have the capacity to emerge from subterranean structures once again or to create seeds that will take root in newly accessible sunshine and nutrients. Due to their quick growth and capacity to keep the soil stable, these shrubs facilitate the establishment and flourishing of other plant species.

Thus, the ideal selection is option A.
