In postmortem analysis, the central blood is collected from the heart. This specimen is, however, susceptible to clotting.
Where does postmortem analysis central blood come from?In situations when femoral samples are not accessible, such as in burned or decomposed bodies, blood may also be taken from central veins, the subclavian vein, or heart chambers for forensic purposes.
Where should blood samples be taken for postmortem toxicological analysis?The femoral vein should be punctured with a 10 mL or 20 mL hypodermic syringe for the greatest results. To maximise specimen volume before sampling, the leg shouldn't be rubbed. Vitreous fluid is frequently taken during forensic postmortem examinations for toxicological study.

Explanation:
Name two reasons that viruses are considered nonliving.
Answer:
The virus simply can't replicate. Viruses fail the second question for the same reason. ... Finally, a virus isn't considered living because it doesn't need to consume energy to survive, nor is it able to regulate its own temperature. Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
Explanation:
Viruses, like bacteria, are microscopic and cause human diseases. ... Viruses also lack the properties of living things: They have no energy metabolism, they do not grow, they produce no waste products, and they do not respond to stimuli. They also don't reproduce independently but must replicate by invading living cells.

why is protein synthesis diffrent in prokaryotes and eukaryotes?
Answer:
In prokaryotes, translation occurs in the cytoplasm, where the large and small subunits of the ribosome bind to the mRNA. In eukaryotes, translation occurs in the cytosol or across the membrane of the endoplasmic reticulum where the entire ribosome/mRNA complex binds to the outer membrane of the rough endoplasmic reticulum and the new protein is synthesized and released into the ER; the newly created polypeptide can be stored inside the ER for future vesicle transport and secretion outside the cell, or immediately secreted.
What property of water enables it to make the journey from the roots to the leaves? The fact that it is a liquid The fact that it is cohesive The fact that it has the ability to flow in any direction o The fact that it is found in the ground
Answer:
The correct answer is - The fact that it is cohesive
Explanation:
Capillary action is the attraction and property that allows water to move from the roots to the leaves and other parts against the force of gravity. It includes cohesion and adhesion property that combinedly makes the capillary action. The capillary action helps in the water movement to the xylem tubes to the parts of the stem and leaves.
Cohesive property is a property that holds the particles or molecules together of an object or a liquid, it is an intermolecular attraction that helps in developing surface tension of the liquid.

Notice the differences in the number of amino acids in cytochrome c between each organism and humans. How might these differences explain the relatedness for each organism to humans
Answer:The closer to the human cytochrome c sequence (identity then similarity of amino acid sequence) the more related the species to humans.
Explanation:
The more similar an organism's amino acid sequence is to the human cytochrome c sequence, the closer the organism is to humans. protein to compare them to human genes can help us determine which is more closely related to humans.
How do organisms differentiate according to amino acid sequence?None of the organisms differ from human Cytochrome C by the same number. In cases like this, examining anatomical structures, an evolutionary tree, or utilizing another protein to compare them to human genes can help us determine which is more closely related to humans.
Cytochrome c has undergone extremely sluggish evolution. Humans and chimpanzees share the same amino acid sequence, however, the rhesus monkey has a single amino acid variation from humans.
Therefore, amino acids in cytochrome c make the result about the relation between humans and other organisms.

Answer: 1. In CF, the body makes abnormal CFTR protein or none at all. Without normal CFTR protein, the cells lining the pathways (tubes) inside some organs make thick, sticky mucus rather than the normal thin, watery kind. Thick mucus can trap bacteria in the lungs, leading to infection, inflammation, and breathing problems. 2. When the CFTR protein is defective, epithelial cells can't regulate the way that chloride (part of the salt called sodium chloride) passes across cell membranes. 3. Mutations in the DMD gene cause the Duchenne and Becker forms of muscular dystrophy. The DMD gene provides instructions for making a protein called dystrophin . This protein is located primarily in skeletal and cardiac muscle, where it helps stabilize and protect muscle fibers. Collapse Section. DMD, the largest known human gene, provides instructions for making a protein called dystrophin. This protein is located primarily in muscles used for movement (skeletal muscles) and in heart (cardiac) muscle. 4. Lack of the dystrophin protein in muscle cells causes them to be fragile and easily damaged. DMD carriers are females who have a normal dystrophin gene on one X chromosome and an abnormal dystrophin gene on the other X chromosome. Most carriers of DMD do not themselves have signs and symptoms of the disease, but a minority do. Symptoms can range from mild skeletal muscle weakness or cardiac involvement to severe weakness or cardiac effects and can begin in childhood or adulthood. 5. Scurvy happens when there is a lack of vitamin C, or ascorbic acid. The deficiency leads to symptoms of weakness, anemia, gum disease, and skin problems. This is because vitamin C is needed for making collagen, an important component in connective tissues. 6. composed of ground substance and fibers.

Why are onion root tips a good choice for viewing cells in different stages of the cell cycle?
The onion root tips are good for observing cells in different stages of cell cycle as they comprise of different cells in different stages of growth and development.
The onion root tip is an actively growing region of the onion plant. The cells are expected to be in different stages of growth and maturation. The cells are in different stages of mitosis which can be observed microscopically. The onion root tip can be prepared for microscopic examination by squashing and flattening of the onion root tip. The chromosomes during different stages of mitosis can be observed by using staining with specific dyes like Feulgen stain and Acetocarmine stain.Learn more about cell cycle:

name two processes for which dna is responsible for
Answer:
Explanation:
DNA contains the instructions needed for an organism to develop, survive and reproduce.
Contains the genetic instructions for the development and function of living things
The main role of DNA in the cell is the long-term storage of information.
The two major processes that the DNA performs in the cell include:
Storage of genetic information Synthesis of protein for the regulation of cellular activities.The DNA stores the genetic information relating to the cell and ensures that the integrity of stored information is preserved and inherited by subsequent generations. It does this by replicating itself in a semi-conservative way and copies of the replicated DNA are inherited by subsequent generations. This is why the DNA is otherwise known as the molecule of hereditary.
DNA is also at the center of protein synthesis. It forms the template for the synthesis of RNA in a process known as transcription and the RNA forms the genetic codes for the synthesis of protein.
Hence, storage of genetic information and indirect regulation of cellular processes are two major processes attributable to the DNA.
