Answer:
Electrons are the negatively charged particles of an atom. Together, all of the electrons of an atom create a negative charge that balances the positive charge of the protons in the atomic nucleus. Electrons are extremely small compared to all of the other parts of the atom. The mass of an electron is almost 1,000 times smaller than the mass of a proton.

Describe one way the plants in a desert biome are adapted to survive?
Answer:
The leaves and stems of many desert plants have a thick, waxy covering. This waxy substance does not cover the stomata, but it covers most of the leaves, keeping the plants cooler and reducing evaporative loss. Small leaves on desert plants also help reduce moisture loss during transpiration.

What statement is correct about the polarity of a water molecule?
Which of the following best describes the effect of a greater number of cysteine amino acids on the stability of the proteins
Answer:
The correct answer is -
The change leads to increased protein stability because of an increased number of S-S bonds in the tertiary structure of the proteins.
Explanation:
Cysteine is a special amino acid due to having a free thiol group that can react and forms a sulfur-sulfur bond with another thiol of another cysteine in a protein structure.
These disulfide bonds can stabilize proteins if formed properly and promote stability to the tertiary structure of the proteins. The more the cysteine, the greater the number of thiols, and the greater the s-s bond in the proteins and more stability to the protein.
Two things that can break enzymes down are:
Answer:
Temperature or heat energy can affect the functioning of an enzyme

How does the structure of an amino acid relate to its function in cellular processes?
Explanation:
Protein function is directly related to the structure of that protein. A protein's specific shape determines its function. If the three-dimensional structure of the protein is altered because of a change in the structure of the amino acids, the protein becomes denatured and does not perform its function as expected.☺. How long has it taken barren rock to become paradise?
Answer:
Volcanoes are created over approximately 10,000-500,000 years by thousands of eruptions -- each lava flow covering the one before it. In the case of oceanic island volcanoes, lava erupts first from fissures, or cracks, on the deep ocean floor. The flows continue to build up and finally an island emerges from the sea.

Which of the following statements is supported by the principles of cell theory?
I. Certain cells can form on their own, without requiring a parent cell.
II. Genetic information is passed from a parent cell to a daughter cell.
III. The basic units of all living things are organelles.
Answer:
the statement that is correct is the lll.
The statement which is supported by the principles of cell theory is as follows:
Genetic information is passed from a parent cell to a daughter cell.Thus, the correct option for this question is B.
What is Cell theory?Cell theory was proposed by two famous scientists known as M.J. Schleiden and T. Schwann. The principles of cell theory are as follows:
All living organisms whether plants or animals are made up of cells.A cell is the smallest unit of all living organisms.A Cell is the structural and functional unit of organisms.This cell theory was further refined by German biologist Rudolf Virchow in 1855. According to him, all cells are arising from a pre-existing cell. A Virus is an exception to the cell theory.
Originally, none of the given statements exactly matches any one of the three principles of cell theory. But the second option reached approximately near around it.
Therefore, the correct option for this question is B.

earth can support the survival of organisms.what is/are the factory/s that make/s earth habitable?
Answer:
The factors that make Earth support the survival of organisms are it's correct distance from the sun, the Earth is protected by solar radiation by it's magnetic field, stability of it's warm atmosphere, availability of some chemical composition that support life like oxygen, water, nitrogen e.t.c., proximity of the sun in allowing the passage and flow of water, the shape and size of the Earth as Rocky planet e.t.c.
Explanation:
Earth is the planets that support the survival of living organisms and this is because of the following factors that support the existence of life and these factors includeit's correct distance from the sun, the Earth is protected by solar radiation by it's magnetic field, stability of it's warm atmosphere, availability of some chemical composition that support life like oxygen, water, nitrogen e.t.c., proximity of the sun in allowing the passage and flow of water, the shape and size of the Earth as Rocky planet e.t.c.
It's correct distance from the sun makes it's to have stable temperature i.e not to hot and not too cold. With the temperature, living organisms can survive and live.
Earth is protected from solar radiation by ozone layer and it's magnetic field. This layer hinders the penetrations of some harmful Ray's it radiations that can damage it destroy living organisms.
It's allow water flow and water is essential for life . It is useful for plants for growth , photosynthesis and germination. Water is essential for animals because, it's aids digestion and metabolic processes.
Earth's atmosphere have right composition of chemicals that support life and these chemicals include oxygen, nitrogen, carbon, water e.t.c.
For example oxygen is important for respiration which releases energy to perform cellular activities.

The phenotype of an organism ?
- represents its genetic composition.
- occurs only in dominant pure organisms.
- cannot be seen.
- reflects all the traits that are actually expressed
HELP PLEASE
Answer:
The phenotype of an organism reflects all the traits that are actually expressed.
Explanation:
Phenotype refers to the visible or evidentiable characteristics that depend on the genotype, which is stored in the DNA. Phenotypic expression, mainly determined by genes, also depends on the influence of the environment on the individual.
Although the phenotype expresses characteristics such as skin, eye and hair color, height or shape of the nose, some characteristics are not entirely visible, such as specific functions or synthesized proteins.
The other options are not correct because:
Represents its genetic composition: this is genotype. Phenotype occurs in all individuals, both dominant and recessive.Many phenotypical characteristics are visible.
