Answer: A. an interacting group of populations that occupy the same area.
The best describes a community is it is an interacting group of populations that occupy the same area. The correct option is A.
What is a community?A community, commonly referred to as a biota is a group of organisms that coexist and communicate with one another within a habitat or environment. An ecosystem is made up of both the biotic community and the abiotic components, such as the physical environment.
Savanna is a good illustration. For protection, zebras and wild animals coexist in huge numbers. Herbivores are preyed upon by predators like lions and eagles for food.
There are two types of community:
Major - these are the big ecological unit, that regulates the flow of energy.
Minor - These are small communities that make up big communities.
Thus, the correct option is A. an interacting group of populations that occupy the same area.

7. Explore and discuss homeostasis imbalances (issues that cause problems) including gallstones, heartburn, ulcers , dehydration, diarrhea, cirrchosis and cancers of the digestive system. **look up these conditions
Answers
1. Gallstones: The precipitation of excess bladder cholesterol into solid crystals is a prerequisite for cholesterol bladder formation, which is caused by disturbed bladder homeostasis. ... We have previously seen that bile and bladder osteopontin (OPN) levels are decreased in gallbladder patients.
2. Ulcers: Gastric bleeding is a major complication of peptic ulcer. Infection by H. Pylori leads to an imbalance of body iron homeostasis, as the increasing demand for iron is the same. Like other types of bacteria, iron is also essential for H growth.
3. Dehydration: If we are low on water, our bodies reduce the sweat and urine we produce to reduce fluid. Most of these reactions are effective under normal conditions and can restore water levels to homeostasis.
4. Diarrhoea: Bile acids, bacterial enterotoxins and neoplasm-derived secrets disrupt this homeostatic state, for example, leading to diarrhea. ... Different infectious organisms (eg bacteria, protozoa, viruses) use different mechanisms to cause intestinal infection and dysentery.
5. Cirrhosis: Disturbed volume homeostasis in patients with cirrhosis of the liver. ... Patients with moderately developed cirrhosis often show a characteristic circulatory disturbance, including arterial hypotension and urinary sodium retention by the kidney, which may lead to edema and ascites.
6. Cancer: Cancer, in this example, breaks down in the balance between cell growth and cell death. The gene that over-expresses anti-apoptotic genes and rejects pro-apoptotic genes is not understood, and it is often unknown why homeostatic equilibrium is lost (perhaps another term for carcinogenesis).

The Fast Plants® shown below follow the same genetic rules as the plants in the Gizmo. What is wrong with this picture?
Answers
Answer:
A
Explanation:
The genotypic mix of the two genes, or alleles, that make up an expressed trait is what causes it. Additionally, a specific gene produces a distinct protein that establishes an individual's physical traits. This is how traits are controlled by genes. Thus, option A is correct.
What is the effect of genetic rules in the Gizmo?The genotype, or set of genes an organism acquired from its parents, is ultimately responsible for the qualities that creature manifests. Each chromosome in an animal has two copies, one from each parent.
Cloning and fingerprinting are two potential applications for DNA-based identification technology.

What cell structure is responsible for regulating all cellular activities?
Choose 1 answer:
A. Nucleus
B. Mitochondria
C. Lysosome
D. Golgi body
Answers
Answer:
Let me know if this is right Answer: Nucleus
Explanation:
This organelle known as the Nucleus has two major functions: it stores the cell's hereditary material, or DNA, and it coordinates the cell's activities, which include growth, intermediary metabolism, protein synthesis, and reproduction (cell division). Only the cells of advanced organisms, known as eukaryotes, have a nucleus.
Answer:
Lysosome
Explanation:
The lysosome is the cell’s recycling center. These organelles are spheres full of enzymes ready to hydrolyze, (chop up the chemical bonds of) whatever substance crosses the membrane, so the cell can reuse the raw material. These disposal enzymes only function properly in environments with a pH level of 5, two orders of magnitude more acidic than the cell’s internal pH level of 7. Lysosomal proteins only being active in an acidic environment acts as safety mechanism for the rest of the cell - if the lysosome were to somehow leak or burst, the degradative enzymes would inactivate before they chopped up proteins the cell still needed.
Living things that are well adapted to their environment survive and reproduce. Those that are not well adapted don’t survive and reproduce. An adaptation is any characteristic that increases fitness, which is defined as the ability to survive and reproduce. What characteristic of the mice is an adaptation that increased their fitness?
Answers
The tendency of an organism to reproduce and survive in the environment in which they thrive is termed as fitness of that organism.
• The mice are considered to be the second most successful mammal on the planet today.
• Mice possesses the tendency to change with the stresses and environment in which they thrive.
• Due to their close association with humans, house mice possess the tendency to live in very dry or hot conditions or in very cold conditions where they could not survive alone.
• The mice possesses the tendency to reproduce at a very high rate, thus, there are always individuals, which can survive.
• They have the tendency to sense their surroundings like other mammals, they even possess good hearing and vision.
• They have large cup shaped ears, which assists them to sense vibrations of sound.
• They also possess good sense of smell and whiskers that helps them to feel air movements and feel surface textures.
Thus, mice are equipped with several elements that helps them to adapt in the environment in which they live, that is, have increased fitness level.

Consuming too much protein or excess amino acids can contribute to
Answers
Consuming too much protein or excess amino acids can contribute to dehydration, hence option E is correct.
What is a high-protein diet?A high-protein diet defines as when you consume an excess of protein in a diet that is higher than the normal need of the body.
The research suggests, is that high-protein diets can cause dehydration. Protein is composed of amino acid which is made of nitrogen. When a person consumes large amounts of protein, the body washes out excess nitrogen with fluids and water.
A higher amount of protein consumed is generally stored as fat, while the excess of amino acids is excreted. This can cause weight gain after some time, specifically if you take too many calories while trying to increase your protein input.
Therefore, high protein or excess amino acids can contribute to dehydration.

How does the air we inhale compare to the air we exhale?
A. The air we inhale has the same percentage of oxygen as the air we exhale.
B. The air we inhale has a greater percentage of oxygen than the air we exhale.
C. The air we inhale has the same percentage of carbon dioxide as the air we exhale.
D. The air we inhale has a greater percentage of carbon dioxide than the air we exhale.
Answers
Answer:
B. The air we inhale has a greater percentage of oxygen than the air we exhale.
Explanation:
First, inhaled air contains about 21% oxygen. Some proportion of this oxygen is used to oxygenate the blood in the alveoli of the lungs for eventual use in cellular respiration. Hence, the proportion of oxygen in exhaled air will be significantly lesser than the proportion of oxygen in inhaled air. Indeed, exhaled air contains about 16% oxygen.
On the contrary, the air we inhale has a lesser percentage of carbon dioxide (0.04%) than the air we exhale (4.4%) due to the additional carbon dioxide produced as a byproduct of cellular respiration—which must be excreted by the lungs.

D.rivers
Explanation:
Ridges feature separates the watersheds. Therefore, the correct option is C.
What are Watersheds?A watershed is a piece of land that directs water into a particular body of water. A watershed exists for every body of water. Rainfall and melting are channelled into rivers and streams by watersheds.
Lakes, bays, and oceans are among the bigger bodies of water that these smaller ones flow into. Water travels across the landscape with the assistance of gravity.
The area of land known as a watershed is responsible for directing precipitation and snowfall into creeks, streams, and rivers, and ultimately outflow places like reservoirs, bays, and the ocean.
A small mountain creek's watershed may only be a few square meters in size. Some watersheds are very large and typically cover numerous smaller ones. Ridges separates the watersheds
Therefore, the correct option is C.
