Answer:
Because velocity has magnitude and direction, speed is not a vector quantity since it only has magnitude
For example, if a car is moving backwards with a speed of 40m/s
Your velocity is - 40m/s
Speed is 40m/s

Holds instruétions for making proteins
Answer:
El ARN mensajero (ARNm) lleva las instrucciones para producir proteínas. Como el ADN, las proteínas son polímeros: largas cadenas ensambladas a partir de unidades moleculares prefabricadas que, en el caso de las proteínas, son aminoácidos. Una gran máquina molecular * llamada ribosoma traduce el código del ARNm y ensambla las proteínas.

Which of the following is NOT a part of an organism’s niche?
A. Behavior
B. Habitat
C. Equilibrium
D. Physiology
Answer:
D
Explanation:
D
Organism's niche does not include equilibrium. The correct option is C.
What is a niche?A species' niche is the primary role in the ecosystem. A niche, in other words, is how an organism "makes a living." The organism's role in the flow of energy through the ecosystem will be included in the niche.
Physiological traits are closely related to an organism's phylogeny and determine its environmental niche.
Thus, an organism's niche does not include equilibrium. The correct option is C.

What do amino acids, fatty acids, and sugars have in common
A. They are used to make proteins.
B. They are used to lipids.
C. They are made of carbon, oxygen, and nitrogen.
D. They are made of carbon, oxygen, and hydrogen.
Answer:
The answer to this question is C. They are made of carbon, oxygen, and nitrogen.
Explanation:
Have a great day and good luck!
The amino acids, fatty acids, and sugars have in common are they are made of carbon, oxygen, and hydrogen. The correct option is D.
What are amino acids and sugars?Amino acids are organic compounds that are made up of amine and carboxylic groups. They are the building blocks of protein. The basic particle of amino acids is C, H, and O.
Sugars are sweet carbohydrates. They are made up of carbon, hydrogen, and oxygen. The fundamental formula of sugar is C6H12O6. They are the primary source of energy.
Fatty acids provide the structural strength to the body. They are made of carboxylic acid and aliphatic chains. They can be saturated or unsaturated. So these molecules have the same elements, from which they are made.
Thus, the correct option is D. They are made of carbon, oxygen, and hydrogen.

There is a large amount of variety in the eye color of human beings. Eye color variation depends on the dominant or recessive alleles. Such a broad spectrum of colors can be attributed to... A. malnutrition. B. multiple alleles. C. a lack of alleles.
Answer:
Eye color is determined by variations in a person's genes. Most of the genes associated with eye color are involved in the production, transport, or storage of a pigment called melanin. Eye color is directly related to the amount and quality of melanin in the front layers of the iris.
The broad spectrum of colors can be attributed to multiple alleles. The correct option is B.
What is variation in human traits?Variation is a word used for different traits present within the species, variation occurs due to recessive and dominant genes present in the organisms and due to mutation.
Mendel gave this theory that the alleles are given independently by the parents and one become recessive and one becomes dominant.
The difference in eye color is due to these alleles. Suppose the mother has black eyes and the father has blue eyes, the child can have both alleles, but only one will show. Mutation can also cause variation, maybe the child has totally different eyes than his parents.
Thus, the correct option is B. multiple alleles.

be classified as which type of biomolecule?
A lipids
B proteins
C nucleic acids
D carbohydrates
The original molecules should be classified as carbohydrates, the correct option is D.
What are carbohydrates?A carbohydrate is a biomolecule comprised of carbon, hydrogen, along with oxygen atoms in a ratio 2:1 hydrogen-oxygen atom ratio.
Carbohydrates are the key source of energy in the body, fueling person's brain, kidneys, heart muscles, additionally central nervous system.
Fiber, for instance, is a carbohydrate that aids digestion, makes one feel full, as well as helps keep blood cholesterol levels in control.
Sugars are the smallest having relatively low molecular weight carbohydrates, which are monosaccharides and disaccharides.
Carbohydrates are a macronutrient and the body's primary source of energy along with proteins and fats.
They consist of starches, sugars, and fiber. Fibers and starch are complex carbs, whereas sugars are simple carbs.

Why does cells divide instead of just grow larger?
Hello there :). Here is why cells divide instead of growing larger:
The larger a cell becomes, the more demands the cell places on its DNA. In addition, the cell has more trouble moving enough nutrients and wastes across the cell membrane. In time, the cell's DNA would no longer be able to serve the increasing needs of the growing cell.
