Answer:

C. bacteria genetically modified to be antibiotic-resistant

Explanation:

Genetically modifying organisms can be either beneficial or harmful for humans. As we can be infected by bacteria, we developed antibiotics to fight those infections, and this saves many lives as it is an efficient medicine. But when a bacteria is genetically modified to be resistant to antibiotics, we can be harmed as we don't have a way to fight the infection and the bacteria will spread (even maybe kill us). Therefore, bacteria that are antibiotic-resistant do not benefit humans, and the correct answer is C. bacteria is genetically modified to be antibiotic resistant.

A gated channel in a cell membrane allows

Ne4ueva [31]

A gated channel is an example of facilitated diffusion. A gated channel protein is a transport protein that opens a "gate" allowing a molecule to pass through the membrane (usually molecules too big to enter the cell by passing through the membrane itself). Gated channels have a binding site that is specific for a given molecule or ion. (meaning only certain molecules or ions can enter the channel).

vlada-n [284]

Answer;

-Chitin is a structural carbohydrate that forms their exoskeleton

Explanation;

-Chitin is the main component in the exoskeletons of arthropods and crustaceans and is also in the cell walls of fungi.

-It is a linear long chain polymer consisting of repeated units of N-acetyl-glucosamine.

-The main function of the chitin-containing exoskeleton is to keep the inner soft tissue safe from any sort of injury and also prevents the delicate tissues from drying (acts as a water tight barrier against dehydration).

Traits controlled by organellar dna do not show mendelian inheritance because

Lapatulllka [165]

Answer:

In mendelian inheritance, the alleles for a gene show normal dominant-recessive relationship. Chromosomes also show crossover due to which new random combination of traits is possible in the offspring. This crossover takes place between homologous chromosomes during meiosis I.

Organellar DNA like the ones present in mitochondria and chloroplast do not follow mendelian inheritance because unlike nuclear chromosomes they do not have cross over events. There is no orderly segregation of alleles during meiosis. Traits controlled by them are usually inherited as it is and usually it is from the maternal parent because paternal gamete like sperm does not contain mitochondria.
