How are chromosomes passed down to offspring in sexually reproducing organisms?(1 point).
The male and female reproductive cells used in sexual reproduction are referred to as gametes, or just sperm and eggs. The number of chromosomes in each gamete is half that of the organism's other cells. Genetic material is combined when an egg and a sperm come together, a process known as fertilization.
Animals that reproduce sexually have gametes that contain half as many chromosomes as the parents. As a result, when male and female gametes combine during fertilization, the resulting progeny will have the same quantity of DNA or chromosomes as their parents.

What is the genotype of the purple and white flower in the P generation?
One purple allele (P) and one white allele are present in all F1 plants (p). The alleles for each gene in the plant make up the genotype. Here, Pp is the genotype. A plant is homozygous if it has two copies of the same allele.
Since the monohybrid cross only involves one feature, the blossom color, it is examined. For the F1 generation, there were gametes P and p. As a result, all of the genotypes are present in the progeny during the F1 generation: Pp or heterozygous purple flowers, which are all purple flowers (phenotype similar). The dominant trait color, purple, has repressed the white color trait.

What are the 3 main types of contamination?
The three major types of contamination are physical contamination, chemical contamination, and biological contamination.
Contamination is the presence of refuse such as dust as well as particles during in the production and transportation processes. Any unwanted matter found inside the product is referred to as a contaminant. These contaminants have an impact on the product's or process's quality. Cross contamination occurs when unwanted matter has been introduced or transferred from one manufacturing process to the next.
Physical contamination would occur if a leak in the retaining containment contaminated the product inside.
An example of chemical contamination is when a product would be stored in a container which it previously held some other product but was not cleaned properly. The remaining product's chemical composition may introduce impurities into the new product, contaminating it.
Bacteria may thrive in biological contamination if the container also isn't properly cleaned and dried. The contaminated container then will affect the product, potentially introducing microbes into the batch.

The descriptions that apply to the ribosome is a cellular structure that is composed of both RNA and protein.
All cells contain ribosome, which are macromolecular organisms that carry out biological protein synthesis (mRNA translation). To create polypeptide chains, ribosomes combine amino acids in the order dictated by the codons of messenger RNA (mRNA) molecules. The short and big ribosomal subunits are the two main parts of ribosomes. Each subunit is made up of numerous ribosomal proteins and one or more ribosomal RNA (rRNA) molecules (RPs or r-proteins). The translational apparatus also refers to the ribosomes and related components. A messenger RNA chain is produced from the DNA sequence that specifies the order of the amino acids in a protein. Messenger RNAs are bound by ribosomes, which use their sequences to determine the proper arrangement of amino acids to produce a specific protein. Transfer RNA (tRNA) molecules choose which amino acids to transport to the ribosome and then bind to the messenger RNA chain via an anti-codon stem loop. There is a specific transfer RNA that must precisely match the anti-codon of each coding triplet (codon) in the messenger RNA and carries the appropriate amino acid for incorporation into a developing polypeptide chain. After the protein has been created, it can fold to create a useful three-dimensional structure.

What is the endoplasmic reticulum responsible for?
The endoplasmic reticulum (ER) is a dynamic organelle that regulates intracellular calcium stages and is answerable for many mobile features inclusive of protein and lipid synthesis.
The endoplasmic reticulum is the transport system of eukaryotic cells, but it also performs many other important functions such as protein folding. It includes two subsets: Rough endoplasmic reticulum and smooth endoplasmic reticulum.
The endoplasmic reticulum forms an interconnected network of flattened vesicles surrounded by membranes called cisterns and tubular structures in most eukaryotic cells. The ER membrane is connected to the outer nuclear membrane. Red blood cells and sperm do not contain endoplasmic reticulum. The endoplasmic reticulum performs several common functions, including folding protein molecules into vesicles called reservoirs and transporting the synthesized proteins to the Golgi apparatus in vesicles. The rough endoplasmic reticulum is also responsible for protein synthesis.

Diffusion, pinocytosis, carrier-mediated transport, and transcellular transport are the mechanisms that control the movement of molecules across membranes.
What is diffusion ?Diffusion is the overall net movement of anything from a higher concentration to a lower concentration. A gradient in the Gibbs free energy or chemical potential drives diffusion.
The process by which cells take in molecules by engulfing them is known as endocytosis. The substance to be carried is caught in a little invagination that the plasma membrane forms that extends inward.
The terms "concentration gradient," "pressure gradient," and "temperature gradient" are used to describe changes in concentration, pressure, and temperature over a given distance. The Latin term diffundere, which meaning "to spread out," is the root of the English word diffusion.
