Answer:
what is microscope is a laboratory instrument used to examine objects that are too small to be seen by the naked eye.
FUNCTIONS : The microscope is one of the most important tools used in chemistry and biology. This instrument allows a scientist or doctor to magnify an object to look at it in detail. Many types of microscopes exist, allowing different levels of magnification and producing different types of images
A karyotype is an organized profile of a person's chromosomes. Two chromosomes specify sex, XX for female and XY for male. The rest are arranged in pairs, numbered 1 through 22, from largest to smallest. This arrangement helps scientists quickly identify chromosomal alterations that may result in a genetic disorder.
Answer & explanation:
The cell was discovered in 1669 by the English scientist Robert Hooke when looking at a piece of tissue in a two-lens microscope. Hooke was able to visualize small cavities in the experiment piece, then naming such cell cavities.
Only a century and a half after the discovery of the cell, that the Cell Theory was launched, replacing the theory of spontaneous generation (or abiogenesis).
Before that, many scientists were already busy understanding the structure and functioning of the cell, generating knowledge that became fundamental to the development of biology, specifically cytology, a branch of science that studies the structure, functions and development of cells.
(D) Most of the best sites are inaccessible by land transportation, so making roads to them is often prohibitively expensive.
<h3>What is a Reserve?</h3>
A nature reserve, also referred to as a wildlife refuge, a wildlife sanctuary, a biosphere reserve or bioreserve, a natural or nature preserve, or a nature conservation area, is a protected area that is important for its flora, fauna, or features of geological or other special interest. It is reserved and managed for conservation efforts as well as to offer unique opportunities for study and research.
In some nations, government agencies may designate them, as well as private landowners like charities and research facilities. Depending on the level of protection provided by local regulations, nature reserves are classified into various IUCN categories. It is typically subject to stricter protection than a natural park. In laws and official documents, different jurisdictions may use different wording, such as ecological protection area or private protected area.

Answer:
soil and vegetative matter screening for soil structure integrity and invasive pathogens
Explanation:
Repeated use of fertilizer causes the soil to break down and lose it nutrient capacity. This in turn will affect the integrity of the plants, now in a nutrient deficit environment. In addition to this, soil micro-biome environment may also be compromised once soil structure and nutrient is lost. Some of the bacteria, fungi and protozoan in the soil plays a role in defense against invasive pathogens. When this is lost the possibility for infection and increased risk of unknown pest and disease is imminent.
