Answer:
D - Sexual reproduction produces offspring which are different from their parents. Asexual reproduction produces offspring which are identical to their parent.
Answer:
just trying to get more points because I need them also this old so yeah
Explanation:
yeah yeah yeah yeah
Explanation:
Mutations increase variation within a population.
During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes. There are two types:
- somatic: these only occur within certain cells, and arise from environmental factors such as UV light
- hereditary: occur within germ cells of the parent and later the fertilized egg which forms a zygote; these are present within all cells of the new organism.
Further Explanation:
During reproduction other events, such as crossing over during mitosis and meiosis, mutations lead to increases in genetic variation. This variation refers to the genetic characteristics present within a species. Mutations may be either beneficial or deleterious; they are maintained within cells, as they form new traits called alleles. Beneficial mutations may confer traits that increase the fitness of a species, along with ensuring survival by conferring a protective advantage- these phenotypic differences between organisms are called adaptations.
Sequences of DNA make up genes which can have different forms called alleles. DNA, which makes up the genotype, is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins which make up the phenotype of an organism.Mutations in DNA sequences affect the corresponding mRNA and thus the protein encoded.

<h2>Problem of protein alters the movement of Ions </h2>
Explanation:
- Proteins are tiny machines that do explicit occupations inside a cell. The directions for building every protein are encoded in DNA. Proteins are gathered from building squares called amino acids.
- The CFTR protein is comprised of 1,480 amino acids. When the CFTR protein chain is made, it is collapsed into a particular 3-D shape. The CFTR protein is formed like a cylinder that experiences the film encompassing the cell, similar to a straw experience the plastic top on a cup.
- In individuals with CF, changes in the CFTR quality can cause the accompanying issues with the CFTR protein:
- It doesn't function admirably
- It isn't delivered in adequate amounts
- It isn't delivered in any way
- At the point when any of these issues happen, the chloride particles are caught inside the cell, and water is never again pulled in to the space outside the cell. When there is less water outside the cells, the bodily fluid in the aviation routes gets got dried out and thickens, making it smooth the cilia. The cilia can't clear appropriately when thick, clingy bodily fluid overloads them.
Answer:
C. Osmosis
Explanation:
Osmosis is the net movement of solvent molecules, usually water, from a region of lower solute concentration to a region of higher solute concentration through a partially permeable membrane. Osmosis is a very useful for moving materials in and out of the cell.
Solutions are mixtures of solutes and solvents. The main aim of osmosis is for all the mixture part to be uniform and the solvent equally dispersed to all the part of the solution.
Osmosis is controlled to a large extent by concentration gradient.
Diffusion on the otherhand is the movement of molecules of a substance from one position to another.
Facilitated diffusion and active transport are just mechanisms for transport within a cell or a body.
