Layers of fossils in pillars, the rock covering them is dated and we get an exact time of each layer.
Answer:
The correct answer is "pepsin".
Explanation:
Pepsin is an enzyme that catalyzes the hydrolysis of proteins, breaking it down into its subunits called amino acids. Pepsin is an important component of the gastric juice because it contributes largely to proteins digestion. In this case, James is having trouble to digest lean steaks and other protein-rich foods. This problem indicates that James is likely lacking the enzyme pepsin.
A scientist named Hans Christian Gram made 2 kinds of bacteria that is based on their differences in the cell walls. The gram positive and the gram negative.There are differences on these 2. One of it is that Gram negative are more resistant with antibodies compared to the gram positive. Example of these would be pseudomonas aeruginosa while for the positive would be Staphylococcus. Another difference between the 2 would be for flagellar structure in gram negative have 4 rings while positive has only 2.
Answer: Early , Similar
, Mammals
, Share
, Similar
, Would likely
Explanation:
Around 80 million years ago mouse, humans and other mammals shared a common ancestor. The genomes of all mammals are comparatively close.
So humans and mice are very similiar because of common ancestors and also shows similar development patterns as humans.
Hence, the correct answers in sequence is Early , Similar
, Mammals
, Share

, Would likely.
Answer:
Amino acids contain nitrogen; fatty acids and sugars do not.
Explanation:
Genetic material is made of nucleotides, which contain amino acids; fatty acids and sugars are not part of genetic material. - this is false. Genetic material is made of nucleotides, but they are made of a sugar, phosphate group, and a nitrogenous base. Genetic material is transcribed then translated into a string of amino acids called a polypeptide chain.
Amino acids are building blocks to larger molecules; fatty acids and sugars are not. - false, amino acids are building blocks to larger molecules called proteins However, sugars are also building blocks for polysaccharides like starch, and fatty acids can combine to form triglycerides
Amino acids contain nitrogen; fatty acids and sugars do not. - this is true. Fatty acids and sugars are made of carbon, hydrogen, and oxygen. Amino acids contain carbon, hydrogen, oxygen, and nitrogen. They also sometimes contain other molecules in their R groups e.g. Sulphur.
Amino acids make up proteins, which provide energy for the body; fatty acids and sugars do not provide energy. - this is false, fatty acids and sugars can also provide energy
