Why must a forensic anthropologist be able to distinguish between antemortem and perimortem pathology
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.

How do you know if something is alive? Describe some of the characteristics of living things.
Answer:
We can determine if something is a living thing by seeing if they show some of the living characteristics. These characteristics include:
Reproduction - to make more of the same organism
Sensitivity - the ability to detect and react to stimuli
Nutrition - eat and digest food.
Movement - the ability to change its position or location
Respire - to breathe / gas exchange
Excretion - get rid of toxic / materials in excess
All living things show the characteristics above.
For example, we can be sure that robots are not living things because they cannot excrete, respire, or reproduce even if they can move and sense stimuli from outside. We can also be sure that plants are living because they show all characteristics, even for movement, we don't obviously see that, but for example, they may grow towards a light source.
Answer:
To be alive organisms have to include all of the following:
- Made up of a cell or cells
- Has DNA
- Can reproduce
- Responds to the environment
- Grows and develops
- Exchanges energy
- Evolves
Explanation:
Prokaryotic and Eukaryotic cells are both alive because they contain all of the seven necessary characteristics listed above. Viruses are not alive because they do not contain all of the seven characteristics listed above.
Which structures are highlighted? Which structures are highlighted? goblet cells submucosa chondrocytes in lacunae seromucous glands
The image is not given in the question, so the appropriate image is attached below:
Answer:
goblet cells
Explanation:
Goblet cells are the mucin-secreting glands found within epithelia. Their shape and size look like a goblet, hence named goblet cells, and contain narrow bases and wide apex.
The structure highlighted in goblet cells scattered within epithelia. Goblet cells function for producing mucin, create a protective mucus layer and immunoregulation.
Hence, the correct answer is "goblet cells".
why is it important to understand plant physiology in crop/plant production and productivity?in your discussion make sure that you mention related fields/areas in agriculture which specifically require a background of plant physiology
Knowledge of Seed physiology helps in understanding of different physiological and morphological changes that occur during germination. By knowing the different inputs requirement of plants (water, nutrients, sunlight) we can easily manage the plant population to get highest yield.
If bacteria do not contain a nucleus will bacteria still have DNA?
Of course not the DNA is found in two basic forms: a chromosomal loop and ring-like plasmids. The chromosomal loop is literally a looping string of DNA. Since there is no true nucleus in a prokaryotic cell, the DNA is suspended in cytoplasm, or the fluid filling the cell.

which of these organisms are most likely to occupy similar niches in different ecosystem
A. Oak tree and maple tree
B. Kangaroo rat and kangaroo
C. Earthworm and freshwater eel
D. Koala and black bear
Oak tree and maple tree are most likely to occupy similar niches in different ecosystem.
What is an ecosystem?An ecosystem is defined as a system which comprises of all living organisms and physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other for requirement of energy.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

how do you find per capita growth rate over a month?
All you have to do is take the CGR (capita growth rate) percentage you just found and divide it by the number of years, months, etc. The complete formula for annual per capita growth rate is: ((G / N) * 100) / t, where t is the number of years.
How would you improve food safety from a food supplier standpoint (farmer, factory, production, distribution, food scientists) be very specific with your answer and make sure to use facts to justify why you believe the way you do. The explanation must be at least three paragraphs (5-8 sentences)
Answer:
Foods are the basic building blocks of living things, yet they may pose a threat and become harmful to human health in some situations [13]. Many people throughout the world become ill because of the food they eat. These diseases associated with food consumption are referred to as foodborne diseases, and they may result from dangerous microorganisms [14]. Foods can become harmful to human health or even fatal when combined with bacteria, mold, viruses, parasites and chemical toxins [13]. Therefore, it is absolutely necessary that consumers be provided with a safe food supply. The factors involved in the potential threat caused by foods are inappropriate agricultural practices, poor hygiene at any stage of the food chain, lack of preventive controls during processing and preparation of the food, incorrect use of the chemical materials, contaminated raw materials, food and water and inappropriate storage [15].

Answer:
The moon's gravitational pull on the Earth is the main cause of the rise and fall of ocean tides. The moon's gravitational pull causes two bulges of water on the Earth's oceans—one where ocean waters face the moon and the pull is strongest and one where ocean waters face away from the moon and the pull is weakest.
