Which of the following is not an appropriate unit for momentum?

Biology
1 answer:
mariarad [96]3 years ago
5 0

Answer:

Option C us correct.

km • m/S

Explanation:

This is because momentum is result of mass and velocity of an object. Momentum is a vector quantity that is it has magnitude and it's direction is in form of three dimensional.

From the option C, kilometer there is not a unit for mass or velocity it it is a unit for distance, therefore it is incorrect.

Explain the importance of covalent bonds in four macromolecules
nikitadnepr [17]

Covalent bonds is important in four macromolecules such as proteins (polymers of amino acids), nucleic acids (polymers of nucleotides), carbohydrates (polymers of sugars) and lipids (with a variety of modular constituents) because they served as a basic structure of macromolecules.

 In addition, the resulting covalent bond is a result of sharing a pair of electrons, one from each atom or molecular units.

Why is it wrong to say that bread is a compound?
tatiyna

Explanation:

Bread cannot be classified as a compound. Compounds are formed when two or more substances are bonded together chemically, however, mixtures are not chemically bonded.

Bread is a mixture of several compounds such as sugars, proteins, lipids and gases along with a culture of organisms or chemical leavEning agaent. Several of these components

Explanation:

Large chains of monomers form biological macromolecules which carry out many essential functions in the body these can include nucleic acids, carbohydrates, proteins and lipids. These are organic molecules, meaning they're ringed or long-chain Carbons bonded to the elements oxygen (O), hydrogen (H), nitrogen (N) and phosphorus (P).

  • Proteins are structural support molecules comprised of long chains of amino acids joined via peptide (CONH) bonds; these are 20 specific units that are arranged into several macromolecules. Amino acids are absorbed through digestion and are incorporated into the body’s cells to make up organs muscles signal molecules and an alternative energy source.                                                                 Basic makeup: C, H, O, N, S; polar C, O double bonds and N-H bonding
  • Carbohydrates function to supply energy and support molecules they consist of mainly sugars or starches in long chains and rings to form monosaccharide monomers. They include monosaccharides, disaccharides and polysaccharides which describes the type of bonding and the degree of complexity of the polymers.                Basic makeup: C, H, O -with many polar OH groups
  • Lipids function as energy storage and chemical messengers, these include fats, saturated and unsaturated fatty acids with double bonds and steroids and waxes. However, lipids are comprised of fatty acids and glycerol; they do not contain a fixed set of monomers, and unlike the other biological macromolecules, they are not polymers. The arrangement of hydrophobic heads and hydrophobic fatty acid tails can give these non-polar macromolecules hydrophilic and hydrophobic properties.                                                                     Basic makeup: C, H, O; non polar- a triple condensation reaction produces the molecules from a triple hydroxyl (OH) alcohol bonded to three long-chain carboxylic acids.

Tomatoes are genetically modified to have a longer shelf life, slowing the ripening and softening of the tomato. Which best desc
just olya [345]

Answer:

C. (last one)

Explanation:

There is a lot of heavy superstition surrounding the ingestion of genetically modified foods and some people believe that consuming foods modified by different DNA can effect their own. However, this is scientifically impossible as a person's DNA is not something that can be modified by anything as you are born with it and your DNA makes up your entire body. Almost every cell in your body contains at least some DNA, meaning that to modify it, every single cell in your body would have to change
