1. Answer;
-secondary structure;
Explanation;
Protein secondary structure refers to regular, repeated patterns of folding of the protein backbone. The two most common folding patterns are the alpha helix and the beta sheet. In an alpha helix, the polypeptide backbone coils around an imaginary helix axis in clockwise direction. In the beta sheet secondary structure, the polypeptide backbone is nearly fully extended. The R-groups are alternately pointed above and then below the extended backbone.
2. Answer;
- Quaternary structure
Explanation;
-Many proteins are formed from more than one polypeptide chain. The Quaternary structure describes the way in which the different subunits are packed together to form the overall structure of the protein. For example, the human hemoglobin molecule shown below is made of four subunits.
3. Answer;
-Tertiary structure
Explanation;
Tertiary structure refers to the overall folding of the entire polypeptide chain into a specific 3D shape. The tertiary structure of enzymes is often a compact, globular shape.
The tertiary structure is the structure at which polypeptide chains become functional. At this level, every protein has a specific three-dimensional shape and presents functional groups on its outer surface, allowing it to interact with other molecules, and giving it its unique function.
4. Answer;
Primary structure
Explanation;
-It is the simplest level of protein structure and is simply a sequence of amino acids in a polypeptide chain. For example, the hormone insulin has two polypeptide chains, A and B. Each chain has its own set of amino acids, assembled in a particular order. For instance, the sequence of the A chain starts with glycine at the N-terminus and ends with asparagine at the C-terminus, and is different from the sequence of the B chain.
Answer:
Other organic molecules such as fat and protein are also used as fuel in cellular respiration they just take a different pathway than glucose.
Explanation:
Answer:
The early stages of embryo development in fish and humans look strikingly similar while insects develop very differently compared to both fish and humans,
Explanation:
It tells you that fish and humans have very similar embryo development (fetus development) while humans and insects develop very differently. Therefore, that supports the argument that humans are more like fish than insects.
<u>Answer</u>:
1. C. Process one describes cloning and process two describe artificial selection
Through cloning a genetically identical individual is obtained from a single individual. Through artificial selection a hybrid between two individuals with desirable traits is obtained.
2. C. Polygenic
A trait that has a continuous variation has a polygenic inheritance pattern as it is controlled by multiple genes.
3. C. The BW mice would have black and white patches
Codominant genes will produce an individual with an intermediate phenotype as both alleles are simultaneously expressed in the heterozygote.
4. D. Polygenic
Polygenic inheritance occurs when two or more genes determine a trait that has a continuous variation. Each gene has a small effect, but all together have a cumulative effect. Examples of such patterns are height, sking color, eye color, weight etc.
Answer:
19 cm
Explanation:
The total distance traveled by the toy cay would be 19 cm.
<em>The total distance traveled should not be mistaken for total displacement. </em><u><em>W</em></u><u>hile displacement measures the distance and direction from the starting position of the toy car relative to its final position, the total distance traveled is calculated by adding all the movements of the toy car together.</u> Hence;
Total distance traveled = 9 + 4 + 6 = 19 cm
