Answer:

d. Nucleotides link together to form a nucleic acid. Amino acids link together to form a protein.

Explanation:

A nucleotide is a bio-molecule which has a sugar phosphate backbone in which a sugar (deoxyribose / ribose sugar) and a phosphate group is attached to each other alternately through phosphodiester bond and a nitrogenous base is attached to the sugar molecule with the help of N- Glycosidic bond.

In case of nucleic acids (DNA and RNA), nucleotides are the monomer units and when these monomeric units join each other to form a chain of nucleotides they are able to create these polymers known as nucleic acids.

Proteins on the other hand are another class of bio-molecules which are the polymers of monomeric units known as amino acids. In proteins, various amino acids are attached to each other with the help of peptide bond.

What is the best way to show the lead levels in six contaminated water wells?
Marrrta [24]

Answer:

Option B, Barr graph

Explanation:

A bar graph is used for comparing several items all together based on any certain parameter.  

Here, the lead content is the comparison parameter while the six sample of contaminated water wells acts as different items being compared.  

A line graph is good to show a continous varying data set, while a circle graph is good to represent the component constitution of any major substance and a data table is best to represent a data set with multiple attributes.

Hence, option B is correct

vovikov84 [41]

Answer:

The correct answer is - texture gradient.

Explanation:

The texture gradient is a depth cue that is a distortion in comparison of size in objects that are farther or closer. In this cue, it looks denser as u move away from the object.

It is dependent on the sense of the depth perception as Wendell can easily tell that trees on the mountain are far from him as he only sees a dense green patch instead of trees individual trees and space in between in them.

Thus, the correct answer is option - texture gradient.

Nataly_w [17]

Answer:

Cilia

Explanation:

The element which is responsible for this is the Cilia. The form found in a human's respiratory system are known as Motile Cilia and basically act as brooms on the respiratory epithelium lining the respiratory tract. Huge waves of Motile Cilia communicate with one another in order to be able to effectively clean up all dirt and mucus from the lungs in a very organized and unified manner. This helps maintain our respiratory system running as effectively as possible.
