Answer:

Nucleic acids

Explanation:

macromolecules made out of units called nucleotides, come in two naturally occurring varieties: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material found in living organisms, all the way from single-celled bacteria to multicellular mammals like you and me.

BECAUSE THE SIZE OF THE CELL IS RELATED TO ITS FUNCTION.

HOPE IT HELPS YOU

CAN YOU BRAINLEST ME

Answer:

For example, the nerve cells are elongated in shape and are thin and dainty. ... An animal cell does not have a cell wall

Explanation:

The size and shape of a cell are related to its function and are governed by four factors—(1) surface-volume ratio, (2) nucleocytoplasmic ratio, (3) rate of cellular activity, (4) cell associations. (1) Surface-volume Ratio: ADVERTISEMENTS: The cell membrane separates the inner content from the outer environment.

A biotic factor for a grey wolf could be disease or predation, parasites, as long as there is a living thing interacting with your wolves, Abiotic is going to be nonliving things: weather, habitat destruction, wind, the prey cut off by a physical barrier

have a nice day : )

Answer:

The Abiotic factors would be rocks, soil, water, etc. The biotic factors would be the wolf, plants, trees, grass, and other predators and prey.

Answer: In principle, to minimise heat transfer through the building envelope the building shape should be as compact as possible,tending toward a cube.

Explanation:

A building's design should be compact and rounded to reduce heat loss through the surface. The optimum shape would be a sphere, but that is impractical for a building. It would be more practical to construct a building that is cylindrical or dome-shaped.

The optimum shape would be a sphere, but that is impractical for a building. It would be more practical to construct a building that is cylindrical or dome-shaped.

By lowering the building's surface area, this design limits the region where heat may escape from the structure. The surface area to volume ratio should be taken into account while trying to reduce heat loss.

A building that is compact and rounded, such a cylinder or dome, has a lower surface area-to-volume ratio than a building that is rectangular or square and has the same volume. Accordingly, less heat is lost from the building's surface in comparison to the heat that is kept inside the structure.

Additionally, a compact, rounded building will have fewer corners and edges, which are vulnerable to heat loss. Additionally, the structure can be angled to receive as much sun exposure as possible, which can add to the building's heating capacity during the winter.

Therefore, a building's design should be compact and rounded to reduce heat loss through the surface.

The capsid has three functions: 1) it protects the nucleic acid from digestion by enzymes, 2) contains special sites on its surface that allow the virion to attach to a host cell, and 3) provides proteins that enable the virion to penetrate the host cell membrane and, in some cases, to inject the infectious nucleic

Answer:

Bacteria, not humans or animals, become antibiotic-resistant. These bacteria may infect humans and animals, and the infections they cause are harder to treat than those caused by non-resistant bacteria. Antibiotic resistance leads to higher medical costs, prolonged hospital stays, and increased mortality.

Answer:

Nucleotide ( monomer )      

Explained Definition:    

The classes of biological molecules may be grouped into the types of polymers they form and the monomers that act as subunits: Lipids - polymers called diglycerides, triglycerides; monomers are glycerol and fatty acids

1. The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue. The four bases are adenine (A), cytosine (C), guanine (G) and thymine (T). The sugar and phosphate create a backbone down either side of the double helix.

2. Polysaccharides, also called glycans, are large polymers composed of hundreds of monosaccharide monomers. Unlike mono- and disaccharides, polysaccharides are not sweet and, in general, they are not soluble in water. Like disaccharides, the monomeric units of polysaccharides are linked together by glyosidic bonds.

3. Fatty acids form more complex lipid polymers called triglycerides, triacyclglycerols or triacyl glycerides when each single-bonded oxygen molecule bonds to a carbon that's part of a glycerol molecule. ... Triglycerides are also commonly found in foods, especially animal products

4.  polymers are known as polypeptides; monomers are amino acids. Nucleic Acids - polymers are DNA and RNA; monomers are nucleotides, which are in turn consist of a nitrogenous base, pentose sugar, and phosphate group
