An allelle is the alternative form of genes that contribute to human genetic variation.  

Explanation:

Any change in the DNA sequencing which leads to the difference between individuals is called genetic variation.

A trait is the characteristic feature which is passed on from one generation to another.

Different forms of traits expressed by different individuals are characterized by genes present in the DNA. The variant or alternative form of genes which leads to such genetic variation is called an allele. This produces the characteristic differences among humans.

Alleles are found in pairs and can either be recessive or dominant depending upon the genotypes (heterozygous or homozygous).

Characteristics like color of the eye or hair, the height of an individual, length or shape of the nose, and various other specific characteristics are expressed by these alleles .

Students use a compound light microscope to view unicellular organisms collected from pond
Maksim231197 [3]

The statement that describes the utilization of a compound light microscope is better to view the structures of these organisms than a dissecting microscope is as follows:

  • Compound light microscopes have higher magnification.

Thus, the correct option for this question is C.

<h3>What is a Microscope?</h3>

A microscope may be defined as a type of laboratory instrument that is significantly utilized to examine or observe objects that are too small to be visualized by the unaided eye.

Dissecting microscopes possess a lower magnification power as compared to compound light microscopes. Due to this, dissecting microscopes are used to visualize larger objects like tissues. Compound light microscopes use more than one glass lens. These types of microscopes are used to examine living cells.

Therefore, a compound light microscope has higher magnification is a statement that describes the utilization of a compound light microscope is better to view the structures of these organisms than a dissecting microscope. Thus, the correct option for this question is C.

Assessing biodiversity:
Helen [10]

Answer:

The correct answer will be option-A

Explanation:

Biodiversity refers to the diversity of the biological entities present in an ecosystem. Biodiversity has a wide spectrum which not only includes the number of the diversity of the organism but also the interaction between them.

The biodiversity is assessed to study the changes that are taking place in an ecosystem, to study the causes and how the changes affect the human well being.

The assessment decisions ignore the personal interests and the biasness as the aim of the approach is not fulfil the personal needs but to maintain sustainable management of the ecosystem.

Thus, option-A is the correct answer.

What is the equation used to measure liquid pressure?​
klasskru [66]

Set up the equation.

Since gravity and liquid densities are fixed (for the most part), the height of the liquid is the largest variable in the equation. The equation reads as Pfluid = ρgh, where ρ is the density of the liquid, g is the acceleration of gravity, and h is the height of the liquid (or depth of the fluid)
