Answer:
ecosystem
Explanation:
hope this helps
A(n) ecosystem is all the living and nonliving things in a particular area that interact with one another.
What is an ecosystem?A(n) ecosystem is all the living and nonliving things in a particular area that interact with one another. An ecosystem includes the living organisms (plants, animals, and microbes) and the nonliving components (water, air, and soil) that make up the environment in a specific area.
These living and nonliving components of an ecosystem interact with one another, forming complex relationships and feedback loops that help to sustain the ecosystem over time. Ecosystems can vary in size from small ponds to vast oceans, and they can be found in a wide range of environments, from deserts to rainforests.

What are the products of cellular respiration?
Answer ASAP test due
Most of the steps of cellular respiration take place in the mitochondria. Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.
The products of cellular respiration are water, carbon dioxide and energy (ATP). Details about cellular respiration can be found below.
What is cellular respiration?Cellular respiration is the process by which living organisms obtain energy by breaking down food molecules in their cells.
Cellular respiration involves the reaction of glucose and oxygen molecules as reactants to synthesize carbon dioxide gas, water and ATP molecules.
Therefore, the products of cellular respiration are water, carbon dioxide and energy (ATP).

when placed in the same container, oil and water do not mix because
Oil and water do not mix because mix each other because water is a polar solvent while the molecules of oil are non-polar in nature.
What are the characteristics of water?The characteristics of water are as follows:
It is a universal solvent that is polar in nature. It possesses high heat capacity and heat of vaporization. It has properties like cohesion and adhesion. The solid form of water is less dense as compared to its liquid form.Due to differences in their polarity, the molecules of water and oil are not intermingled with each other. Due to this, the polar compounds are dissolved in a polar solvent while non-polar compounds like oil are dissolved in a non-polar solvent. Thus, the molecules of oil will finally stick to each other and are immiscible with water.
Therefore, oil and water do not mix because mix each other because water is a polar solvent while the molecules of oil are non-polar in nature.

Which of the following is NOT a method your body uses to regulate homeostasis? A. change the flow of blood, B. shivering, C. sweating, D. taking a cool shower
Answer:
D. taking a cool shower
Explanation:
Taking a cool shower may not be a method through which the human body regulates homeostasis.
Homeostasis refers to the maintenance of relatively constant internal body processes. Homeostasis happens naturally in the body system.
A change in the flow of blood to the skin may happen in response to a breach to the normal body temperature. Increased blood flow happens in response to high body temperature and decreased flow happens in response to low temperature.
Shivering of the body happens in response to a drop in the normal body temperature. The shivering helps generate more heat for the body.
Sweating happens in response to excessive body temperature. The evaporation of the sweat causes cooling, thereby returning the body to its normal temperature.

Answer: Cells : Cell, in biology, the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed. A single cell is often a complete organism in itself, such as a bacterium or yeast. Other cells acquire specialized functions as they mature.
virus : A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea.
Both : Still, viruses have some important features in common with cell-based life. For instance, they have nucleic acid genomes based on the same genetic code that's used in your cells (and the cells of all living creatures). Also, like cell-based life, viruses have genetic variation and can evolve.

don't get mad
Explanation:
Polysaccharides are 1000s of monosaccharides joined together.These carbohydrates store energy and help build structural compounds. For example, plants use cellulose to build up their cell walls so they can stay rigid and grow towards the sunlight. Plants can store glucose energy in the form of starch in roots, fruits, and seeds. On the other hand, animals store glucose energy in the form of glycogen. When we don't have enough food to eat to replenish glucose in our cells, glycogen will release glucose energy as backup.
True or False??
Answer:
True
Explanation:
As rightly stated in this question, Glycogen is a carbohydrate which animalsa store glucose energy as. When we eat food, all parts is not converted to glucose, some is converted to glycogen, which is then stored in the liver and muscle tissues.
This stored glycogen, which is a polymer of glucose is broken down to glucose for use during a low supply of glucose to the cells. Hence, it is TRUE that when we don't have enough food to eat to replenish glucose in our cells, glycogen will release glucose energy as backup.
