Explanation:
In simple diffusion, small molecules without charges such as oxygen and carbon dioxide flow through a plasma membrane without assistance and without expending energy. Other substances such as proteins, glucose and charged particles called ions cannot pass through the selectively permeable membrane

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.

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.

Which organelle would be more developed in a cell of salivary glands?
Answer:
Lysosomes
Explanation:
Salivary glands are secretory cells, meaning they release substances into the extracellular environment. In the case of the salivary glands, they secrete water, electrolytes, mucus and enzymes, the components of saliva. Therefore, these cells have a very well-developed secretory system.
Lysosomes store secretory proteins and are important for keeping them sequestered from the rest of the cell, and eventually delivering them outside the cell.

Hope it Helps!! :D
The correct answer is C chromosome
Describe a trait.
A distinctive attribute or characteristic of a living thing is what is referred to as a trait. As a result, it alludes to particular traits or qualities that a living thing posses.Based on genetics, a live organism can be distinguished from others by the features that are fundamentally passed on from its parents to its offspring.Additionally, each species is distinct due to features that are controlled by deoxyribonucleic acid (DNA) through the arrangement of its alternating deoxyribose sugars.A trait is a particular quality that an organism possesses. Genes, the environment, or more frequently the relationships between them, can all influence traits. The term genotype refers to the genetic component of a trait.Numerous genes play a role in regulating cell division and development. This process is tightly regulated to guarantee that the DNA of a dividing cell is accurately duplicated, that any DNA errors are corrected, and that each daughter cell obtains a complete set of chromosomes. …Your traits, which are features or characteristics that you inherit from your parents, are determined by the information carried by your genes (say: traits). In the human body, each cell has between 25,000 and 35,000 genes.A gene is a segment of DNA located on a chromosome that codes for the production of a protein that regulates a certain attribute (or characteristic) of the organism. Let's say a plant progeny carries the gene for the trait known as "tallness."thus the correct response is C chromosomes

. 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.

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.(02.04 MC) Which description justifies why the theory of evolution is a theory and not a law?
