The diagram above represents an animal cell. What is the function of X?
It controls energy released.
It regulates the transport of materials.
It produces proteins.
It synthesizes cellulose.
Answer:
X in the diagram represents the cell membrane and performs the function of regulates the transport of materials.
Explanation:
The cell membrane, marked with X in the diagram, is a lipid bilayer with hydrophobic properties, which acts as a semi-permeable membrane to the passage of substances.
This membrane, that covers the cell and keeps it isolated from the extracellular space, has the function of controlling or regulating the passage of materials from the extracellular to the intracellular space, as well as the exit of substances from the interior of the cell. To fulfill this function it has several alternatives of transmembrane transport.
The other options are not correct because:
The cell membrane does not control the energy released. Protein synthesis occurs in the rugged endoplasmic reticulum. Cellulose synthesis occurs inside the cell, a process dependent on photosynthesis.Answer: it regulates the transport of materials

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.

Which of the following happens when a phosphate-phosphate bond in an ATP molecule
is broken?
Lysosome contents are released in a cell.
Energy is released in a cell.
Water is transported into an animal cell
Light energy is absorbed in a plant cell.
Answer:
An event that occurs when a phosphate-phosphate bond is broken in ATP is that energy is released in a cell.
Explanation:
Adenosine triphosphate or ATP is the molecule in charge of providing energy to the cell, which is necessary to perform its functions.
The energy contained in ATP depends on the high-energy bonds that bind the phosphate groups to the energetic nucleotide molecule. Through the hydrolysis of ATP, phosphate is separated from ATP, obtaining ADP, and a large amount of energy is released. This energy serves for the cell to perform its metabolic functions.
The other options are not correct because:
Lysosomes act on cellular digestion. Transport of water into the cell occurs by osmosis, through aquaporins. Light energy is absorbed in a plant cell, through photosynthesis.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.

Use of synthetic fertilizers often leads to the contamination of groundwater with nitrates. Nitrate pollution is also a suspected cause of anoxic "dead zones" in the ocean. Which of the following might help reduce nitrate pollution? Use of synthetic fertilizers often leads to the contamination of groundwater with nitrates. Nitrate pollution is also a suspected cause of anoxic "dead zones" in the ocean. Which of the following might help reduce nitrate pollution? adding nitrifying bacteria to the soil using ammonia instead of nitrate as a fertilizer growing improved crop plants that have nitrogen-fixing enzymes adding denitrifying bacteria to the soil
Answer:
adding denitrifying bacteria to the soil
Explanation:
Denitrifying bacteria refer to microorganisms in soil that carry out the conversion of nitrates in soil to free atmospheric nitrogen.
Nitrogen gas (N2) is ultimately the product of denitrification of soil, however certain intermediate nitrogen species are also formed in the process. Some of these intermediates may include the following sequence of conversion; NO3− → NO2−→ NO + N2O → N2.
The chemical equation for denitrification is; 2 NO3− + 10 e− + 12 H+ → N2 + 6 H2O.

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.

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.
