Explanation:
Bacteria develop resistance mechanisms by using instructions provided by their DNA. Often, resistance genes are found within plasmids, small pieces of DNA that carry genetic instructions from one germ to another. This means that some bacteria can share their DNA and make other germs become resistant.

differentiate between kidneys and lungs
Kidneys are used to excrete urine and toxic wastes. They are very essential for keeping the body clean. Usually it excretes urea, sodium and some salts which are considered as waste in the body.

Explanation:
A technique that can be used to separate proteins based primarily on the presence of non-polar residues on their surface is called A) ion-exchange chromatography. B) gel filtration chromatography. C) affinity chromatography. D) gel electrophoresis. E) hydrophobic interaction chromatography.
Answer:
E) hydrophobic interaction chromatography.
Explanation:
Hydrophobic interaction chromatography (HIC) is a methodology used to separate protein molecules depending on their hydrophobicity. HIC enables the separation and purification of proteins by using a reversible interaction between the target protein and the hydrophobic ligand of a HIC resin such as, for example, methacrylate-based beads. This interaction is influenced by the running buffer (high salt concentrations favor hydrophobic interactions). HIC enables the separation of proteins under low denaturation conditions, thereby preserving their biological functions.
Una especie de mariposa presenta rasgos fenotípicos diferentes entre los miembros de sus poblaciones. Estos rasgos van desde una coloración verdosa y antenas cortas (características recesivas). El fenotipo más común (características dominantes) de esta especie es de coloración amarilla y de antenas tan largas que se pueden doblar. Realice el cruce entre dos mariposas que presentan fenotipo más común, pero de genotipos heterocigotos y determine los posibles rasgos fenotípicos que se pueden presentar.

How do organisms in the rainforest compete for biotic and abiotic factors? (Emergent layer, canopy layer, understory, forest floor?) In the ecosystem. Giving brainliest.
Organisms in the rainforest compete for biotic and abiotic factor by using resources that are available in the surrounding environment.
Competition occurs when the resources are available in scarce or limited amount. When there is an abundant amount of resources, there is no competition between organisms. The organism which is stronger than other organism can use more resources i.e. water, food and space etc and increase its population.
Those organisms which feed on similar food and other resources can compete with each other and the stronger organism will use the resources in large amount.

A boy picks up an earthworm and place it on a white tile. He observed that the earthworm has difficulty in moving forward.
Explain why.
Answer:
A number of tiny hair like bristlez are present on the lower surface pf an earthworm's body. These bristles help it to get a good grip on the surface of q ground.However these bristles donot provide good grip on plain glass tiles.
Earthworms have microscopic hairs or bristles all over their body which provide the necessary traction while movement. These bristles or setae are present on each segment of their body and it imparts the necessary grip or anchorage for forward and backward movement.
Tile is smooth in nature so earthworms cannot move as the setae will not get sufficient surface support to move the body.
