Explain why hunter-gatherer societies were highly mobile.
PLEASE HELP!!!
Answers
Answer:
Hunter and gatherer societies were highly mobile because if the place they they were staying ran out of resources they would have to move. The way that later societies would combat this is by planting farms which could grow back every year and allow them to stay in one place for long periods of time. Hope that helped!
Answer:
Hunter Gatherers rely on the land around them to keep them alive and well, with this being said , if a heard of Buffalo were to move away the village would starve because their main food source would be gone, so they have to “follow their food” and move with nature to stay alive.

Ribulose biphosphate carboxylase is a chemical that aides in the process of photosynthesis. Ribulose biphosphate carboxylase breaks down carbon dioxide and bonds carbon atoms together to begin the formation of sugars. Without ribulose biphosphate carboxylase, photosynthetic organisms would not be able to produce as much food. Even though ribulose biphosphate carboxylase is involved in assisting chemical reactions, its chemical structure is unchanged.
Based on the information about the function of ribulose biphosphate carboxylase, what is the best classification of the chemical?
A.Carbohydrate B.Enzyme C.Lipid D.Nucleic Acid
Answers
Answer:
The correct answer is - B. Enzyme.
Explanation:
RubisCo or ribulose bisphosphate carboxylase is an enzyme and most abundant protein on the earth that catalyzes the formation of the sugars from the CO2 by the photosynthesis process.
As it is given that in absence of the RuBisCo enzyme the cells plants or the photosynthetic organisms are not able to produce as much food as they produce in presence which means it has an essential role in increase the photosynthetic process to produce the food. By this, we can say it is an enzyme that helps in the process of photosynthesis.

In infective endocarditis, septic emboli may break off. What is/are the possible outcome(s) of emboli in the circulation?
Answers
Answer: The possible outcomes of septic emboli in the system is it's ability to cause metastatic infections in various organs of the body.
Explanation:
Infective endocarditis is defined as the infection of the lining of the interior surfaces of the heart chambers ( the endocardium). This infection is usually caused by microorganisms such as bacteria and fungi. One of the major types of complications of infective endocarditis is septic embolism.
Septic embolism is the fungal or bacterial infection of a mass ( blood clot, air bubbles or foreign materials) which breaks off from their original location that has been infected for a long period of time ( example is the infective endocarditis).
The possible outcomes of septic emboli in the system is it's ability to cause metastatic infections in various organs of the body. The organs and organ systems that are mostly affected includes:
--> Central Nervous System,
--> Bone and joint structures
--> Liver,
--> Kidney,
--> Sleen,
--> Lungs and
--> Coronary Vessels.
Depending on the location of the detached emboli in the body complications caused by this effect includes: acute diffuse glomerulonephritis, bacterial meningitis,splenic abscess, pleuritic chest pain,hepatic abscess just to mention a few. I hope this helps, thanks.

DNA found in cytoplasm is correctly pairs a structure in a eukaryotic cell with its description. Thus, option B is correct.
What are Eukaryotes?Eukaryotes (or Eukaryota) are a domain grouping all unicellular or multicellular organisms that are characterized by the presence of a nucleus and usually mitochondria in their cells.
He opposes the domains of Eubacteria and Archaea.Eukaryotes gather four great kingdoms of the living world: animals, mushrooms, plants and protists (or protozoa).
Eukaryotes are organisms whose cells have a nucleus enclosed within membranes. All protists, fungi, plants and animals such as yeasts, fungi, Protozoa and Plant cells are examples of eukaryotes. While prokaryote is a unicellular organism that lacks a membrane-bound nucleus, or any other membrane-bound organelle. Bacteria and blue-green algae are examples of prokaryotic cells.
Therefore, DNA found in cytoplasm is correctly pairs a structure in a eukaryotic cell with its description. Thus, option B is correct.

For this assignment, conduct some independent research on the raccoon and mountain gorilla. You may do your research online or from library books and magazines.
Part 1: Fill in the table below and then answer the questions.
Trait
How many offspring do they have in a year, usually? What do they eat?
Where are they found in the world?
How many are there in the world?
Are they hunted for meat, skin, fur, or other parts?
Part 2:
Which species is most vulnerable to extinction? Give at least three reasons why.
Which species would be most harmed by environmental change that wiped out one area of its habitat? Why?
Answers
Answer:
Raccoon:
1. Mother raccoons can have between two to five babies in a litter, and they will have just one litter per year.
2. Raccoons are omnivores, meaning they will eat both plants and other animals. This includes fruits, berries, nuts, fish, frogs, mussels, crayfish, insects, turtles, mice, rabbits, muskrats and bird eggs.
3. Raccoons can be found natively throughout most of the US and Canada, as well as in parts of Latin America, from Mexico extending down to the northernmost regions of South America.
4. There are only 323 to 955 left in the world.
5. They are hunted for their fur and skin.
Mountain Gorilla:
1. Once they have reached an age of approximately 10 years, female mountain gorillas give birth to one baby every 4 years.
2. They eat roots, shoots, fruit, wild celery, and tree bark and pulp.
3.Mountain gorillas are found in two separate locations: the Virunga range of extinct volcanic mountains on the borders of the Democratic Republic of Congo (DRC), Rwanda and Uganda, and in the Bwindi Impenetrable National Park in Uganda.
4. There are only about 1,000 mountain gorillas left.
5. Not only are they hunted for meat, mountain gorillas are also illegally hunted for trophies and live infants.
Part 2:
The mountain gorrila is most vulnerable to extinction. People hunt for mountain gorillas more than they hunt for raccoons. mountain gorillas are on the endangered list. Not only are the mountain gorillas hunted for their meat but they are killed as trophies. Raccoons are rarely out in the daytime making them harder to hunt.
The raccoons would be most harmed by environmental change. Raccoons live in trees and need places to hide in the day time. Gorillas would be able to adapt better considering they dont need to hide in the trees. Raccoons would then be out in the daytime making it easier for them to be caught.

Gross production is the amount of energy left after cellular respiration. Please select the best answer from the choices provided T or F
Answers
Answer:
FALSE
Explanation:
Gross production is the amount of energy left after cellular respiration that is false, as the gross production is the total production and the net production is the amount of energy left after cellular respiration.
What is the significance of the gross production?Gross production is the total amount of energy produced by an organism through different processes, such as photosynthesis, ingestion, and digestion of food, while after energy is used by the organism for cellular respiration, what is left is called the "net production." Although the gross energy is not released, the net energy is.
Hence, gross production is the amount of energy left after cellular respiration that is false, as the gross production is the total production and the net production is the amount of energy left after cellular respiration.

Attentional Blink is a phenomenon characterized by the individual failing to detect a second visual stimulus that is presented _____ milliseconds after the first stimulus
Answers
Answer:
200 to 500 milliseconds
Explanation:
Attentional blink is a phenomenon that puts time-related limitations to the ability to utilize visual attention. When an individual must identify two visual stimuli presented one after another, the accuracy is very poor for the second stimulus if it occurs within 200 to 500 milliseconds of the first stimulus.
So, in our question, the gap is filled by 200 to 500 milliseconds.
