Answer: Antemortem describes injuries or pathologies inflicted on the victim before the death. Perimortem refers to any injury associated with the manner of death.
Explanation:
A foresen anthropologist is a person who is dedicated to identifying and studying skeletonized human remains and trying to determine markings on the bones that can elucidate the causes of death. In this way, the anthropologist seeks to learn about the events that occurred by studying the injuries and analyzing evidence left at the scene.
The term antemortem is used to describe injuries or pathologies on the victim before his or her death, which, however, have not caused the person's death. On the other hand, the term perimortem refers to injuries or pathologies associated with the manner of death. That is, it is necessary to distinguish between the two to determine the cause of death of the person. Not only has an antemortem injury or pathology not led to death, but it has no relationship to the event. And a perimortem injury or pathology is fatal, it must be focused on in order to clarify the facts and know how the person died.
Confusing an antemortem pathology with a perimortem one or vice versa, can lead to an erroneous diagnosis of the cause of death.

Explain the contribution of antigenic determinant in false negative and false positive test
Answer:
The contribution of the antigenic determinant is given below:
Explanation:
Antigenic determinant or epitope is the part of the antigen that is recognized by the immune cells or antibodies such as the B- cells by binding to these cells and evokes the response in the host. The antibodies bind to the epitope segments only not to the entire antigen protein.
A false-positive test is a test where the result suggests that an individual has a specific condition but in reality not having such condition. opposite in the false-negative So, the antigenic determinant binds to the specific antibodies and shows wide significance to reduce the false-negative or false-positive.

Answer:
New Moon
Explanation:
There are eight phases of the Moon, which repeat every 29.5 days. New Moon. A new moon is usually not visible to the naked eye, as only the unlit portion of the Moon is exposed. This phase occurs when the moon is situated directly between the sun and the Earth. A solar eclipse can only occur during this phase. Waxing Crescent

White blood cells called B cells produce proteins that can be used for the treatment of certain illnesses. However, these B cells do not live for very long on their own. To keep the B cells growing for a long time in laboratories, scientists fuse the B cells with cancer cells (fused B-cancer cells) that do grow for a very long time. The particular cancer cells used for the fusion are treated with chemicals that make them unable to produce the nitrogenous bases adenine and guanine, but the B cells with which they are fused do produce these nitrogenous bases. The scientists grow the large fused B-cancer cells in a growth medium that contains necessary nutrients for the cells and includes a source of carbon.
(a) Describe the role of carbon in biological systems.
(b) The membranes of both B cells and the cancer cells are largely composed of phospholipids. Explain how, when the membranes are fused, the polar parts of the phospholipids from one cell will interact with the phospholipids from the other cell and how the nonpolar parts of the phospholipids from one cell will interact with the phospholipids from the other cell.
(c) Make a claim about the most immediate effect on the fused B-cancer cells if the fused cells are transferred to a growth medium that lacks a source of nitrogen.
(d) Provide reasoning with evidence based on the composition of biological macromolecules to support your claim.

Explanation:
The interactions between human population dynamics and the environment have often been viewed mechanistically. This review elucidates the complexities and contextual specificities of population-environment relationships in a number of domains. It explores the ways in which demographers and other social scientists have sought to understand the relationships among a full range of population dynamics (e.g., population size, growth, density, age and sex composition, migration, urbanization, vital rates) and environmental changes. The chapter briefly reviews a number of the theories for understanding population and the environment and then proceeds to provide a state-of-the-art review of studies that have examined population dynamics and their relationship to five environmental issue areas. The review concludes by relating population-environment research to emerging work on human-environment systems.

You have been looking at meiosis beginning with a diploid cell that has the genotype AaSs. The alleles in the haploid gametes produced by meiosis are
Answer:
AS, As, aS, as
Explanation:
Meiosis is the cell division that involves the production of daughter cells or gametes with a reduced number of chromosomes. i.e. diploid (2n) - haploid (n).
According to Gregor Mendel in his law of Segregation, the alleles of a gene will separate into gametes in such a way that only one allele will be present in each sex cell. Hence, in this diploid cell with genotype AaSs, the alleles will separate into the haploid cell in the following genotype proportion:
AS, As, aS, and as

The movement of glucose across the membrane through facilitated diffusion is a form of passive transport because
Answer:
Explanation:
Glucose is a 6 carbon sugar molecule that provides energy needed by cells. Since glucose is a large molecule, it is difficult to be transported across the membrane through simple diffusion. Therefore, it diffuses across membranes through facilitated diffusion down the concentration gradient.

why are pig/sheep hearts used to study the anatomy of the human heart?
Answer:
Pig hearts are used to study the anatomy of human hearts because they are very similar in structure, size and function to human hearts. These similarities, combined with the fact that they are much more readily available than human hearts, make them an ideal choice for research and study.

Answer:
1. Isovolumetric relaxation.
2. Ventricular filling.
3. Isovolumetric contraction.
4. Ventricular ejection.
5. Ventricular filling.
6. Ventricular ejection.
7. Isovolumetric contraction.
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
Diastole: in this stage, the ventricles is relaxed and would be filled with blood. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.The following terms describe the physical or mecahnical events with the correct phases of the cardiac cycle in mammals (human beings).
1. Isovolumetric relaxation: All 4 cardiac valves are closed and all 4 chambers are relaxed during this phase.
2. Ventricular filling: The maximum amount of blood is in the ventricles at the end of this phase.
3. Isovolumetric contraction: The pressure in the ventricles is higher than in the atria, but lower than in the arteries, during this phase.
4. Ventricular ejection: The semilunar valves are open and the AV valves are closed during this phase.
5. Ventricular filling: The atria contract at the end of this phase.
6. Ventricular ejection: The pressure in the ventricles is higher than the pressure in both the atria and the arteries during this phase.
7. Isovolumetric contraction: Systole begins with this phase.
Define “isotope” using mass number, atomic number, number of protons, neutrons and electrons. (PLEASE HURRY!)
Isotopes have different mass numbers due to different number of neutrons but same atomic number due to same number of electrons and protons.
What are isotopes?
Isotopes are defined as substances having same number of protons but different number of neutrons.Number of protons is characteristic for determining position of elements in the periodic table.
Since,all isotopes have the same number of protons and hence have same position.They have similar chemical properties as they have same number of electrons.
They find applications in the field of nuclear medicine and oil and gas research . There are 2 types of isotopes : stable and unstable
Unstable isotopes are radioactive and are called as radioisotopes.Some of these isotopes are man -made and hence also called as artificial isotopes.Every element has an isotope which is either man-made or natural .
Many properties of isotopes depend on mass which is measured in atomic mass unit. The difference in actual mass and mass number is called mass defect.
