Answer:

Due to its high magnification power.

Explanation:

A scientist used a light microscope to view an algal cells because light microscope is able to magnify objects up to about a thousand times. Various cellular organelles, such as nuclei, chloroplasts, and mitochondria etc can also be seen clearly with the help of light microscope so that's why scientist used light microscope to study algal cells.

Is the importance of an element in the body related to its percentage of body weight? Cite the evidence in the table to support
Otrada [13]

Answer:

Roughly 96 percent of the mass of the human body is made up of just four elements: oxygen, carbon, hydrogen and nitrogen, with a lot of that in the form of water. ... Sulfur is not usually mentioned as a dietary supplement because the body gets plenty of it in proteins. Humans get nitrogen from food. The element is an important component of amino acids, which are used to build peptides and proteins. Nitrogen is also an essential component of the nucleic acids DNA and RNA and all of the other molecules derived from the nitrogenous bases.

<span>A.    </span><span>symbiote.                                                                   C.  capacity limiter</span>

<span>B.      </span><span>producer.                                                                  D.  limiting factor

</span>

The answer is D. Limiting factors limit the ideal growth rate of a population. Examples of these limiting factors include space (low space) and food (scarce food). These limiting factors would limit the population growth rate either by causing emigration, increases birth rate, and decrease birth rate.

Mitochondria and chloroplasts
Grace [21]

Answer:

C. prokaryotic cells

Definitions

The Mitochondrion is an organelle in the cytoplasm of cells that functions in energy production.

Chloroplast is usually defined as a plastic containing chlorophyll.

Chlorophyll is the green coloring matter of leaves and plants, essential to the production in a bluish-black form, C55H72MgN405 (chlorophyll a), and a dark-green form, C55H70MgN4O6 (chlorophyll b).  

A root cell is one of the maestro cells in the human organic structure that has possible ability of turning into any of the more than the organic structure's 200 cell types.  

Prokaryotes is any cellular organism that has no nuclear membrane, no organelles in the cytoplasm except ribosomes, and has its genetic material in the form of single continuous strands forming coils or loops, characteristic of all organisms in the kingdom Monera, as the bacteria and blue-green algae.

<h2>What are the similarities and differences between prokaryotes, mitochondria, and chloroplasts?</h2>

Both mitochondria and heterotrophic prokaryotes, as well as chloroplasts and autotrophic prokaryotes, have a genetic structure (DNA with a circular double helix shape and the genes themselves), as well as comparable ribosome types. In reality, the endosymbiotic idea is based on these parallels.

What does an enzyme’s structure have to do with a catalytic activity?
igomit [66]

Explanation:

The proteins in enzymes are usually globular. The intra and intermolecular bonds that hold proteins in their secondary and tertiary structures are disrupted by changes in temperature and pH. This affects shapes and so the catalytic activity of an enzyme is pH and temperature sensitive.
