ANSWER ON ED
Answer:
They are all true besides "Organisms of the same species are equipped with the same survival skills."-that one is false.
Explanation:
B. can be amplified in volume to result in many copies of the segment.
C. can be cut in specific locations to isolate DNA sequences.
D. can be sorted and mapped.
Answer:
B. can be amplified in volume to result in many copies of the segment.
Explanation:
The purpose of PCR is to amplify small amounts of DNA so that you can get a sample large enough to analyze (or use for some other purpose), especially in a crime scene. A. is referring to restriction enzymes, enzymes that cut at specific locations along DNA strands to create "sticky ends." C. is referring to restriction enzymes once again. D. is simply irrelevant.
Through the use of the polymerase chain reactions (PCR), small amounts of DNA can be amplified in volume to result in many copies of the segment. Thus, the correct option is B.
The polymerase chain reaction is a method widely which is used to rapidly make millions to billions of copies of a specific DNA sample, it also allows the scientists to take a very small sample of DNA and amplify it to a large enough amount to study in detailed study.
Polymerase chain reaction is fundamental to many procedures which are used in genetic testing and research work, including the analysis of ancient samples of DNA and identification of infectious agents as well. In this process, small amounts of DNA can be amplified in volume to result in many copies of the segment.
Therefore, the correct option is B.

Answer:
Carbon foot print measures emission of greenhouse gases from the process under study.
Explanation:
Carbon footprint is a technique to measure impact of particular activity or device on the environmental pollution. The technique measures emission of greenhouse gases such as carbon dioxide, methane and nitrous oxide as well as vapors from the process under study. Carbon footprint represents the pollution caused by particular process in terms of carbon dioxide equivalent.
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.
Secondary structure involves the folding patterns of a protein, such as alpha-helices and beta-sheets, while tertiary structure refers to the overall 3D shape of a single polypeptide chain. Quaternary structure occurs when multiple polypeptides or subunits interact to form a protein complex.
Secondary structure refers to the folding patterns, specifically the alpha-helices and beta-sheets, that are formed in a protein. These structures are maintained by hydrogen bonds between amino acids in different regions of the polypeptide chain.
Tertiary structure is the overall 3D shape of a single polypeptide chain, which is determined by interactions between amino acid residues that are far apart in the chain.
Quaternary structure occurs in proteins that are formed from multiple polypeptides or subunits, and it is stabilized by weak interactions between these subunits.

The four daughter cells are formed during meiosis. It is a reduction division that results in the formation of four haploid daughter cells.
Further Explanation:
Meiosis is the process that supports the division of single-cell twice. It results in the formation of four daughter cells. This process involves DNA replication that occurs in two cycles namely meiosis I and meiosis II. Each cell contains half the number of chromosomes (haploid).
Meiosis I and meiosis II both contain four steps they are prophase, metaphase, anaphase and telophase.
(a) Prophase: It is the first step of the meiotic division that hasthe longest period. It is further divided into five phases depending upon their chromosomal behaviour. The following stages are the leptotene stage, zygotene stage, pachytene stage, diplotene stage and diakinesis.
(b) Metaphase: During this phase, thechromosomes that bivalent in structure get aligned to the equatorial plates through spindle fibres. The microtubules are formed from the opposite poles of the spindle fibre that are attached to each pair of the homologous chromosome.
(c) Anaphase: In this stage, the chromosome is separated whereas the sister chromatids are remains associated at their centromeres.
(d) Telophase: This is the last stage of the cycle in which the nuclear membrane and nucleolus reappear. Cytokinesis of cells takes place and is called a died of cells.

The somatic nervous system does not rely on the autonomic nervous system for involuntary events.
The body system that does not rely on the autonomic nervous system to stimulate involuntary events is the somatic nervous system.
The somatic nervous system controls voluntary actions such as movement of skeletal muscles, while the autonomic nervous system controls involuntary actions such as heartbeat and digestion.
Two examples of systems that are controlled by the autonomic nervous system are the cardiovascular system, which regulates heart rate and blood pressure, and the respiratory system, which controls breathing rate and depth.
