Place the terms into the correct column that describes the reactions of photosynthesis.
MAVERICK [17]

Answer:

In the light-dependent reaction, which occurs in the THYLAKOID MEMBRANE of the chloroplast, energy from SUNLIGHT is used to breakdown WATER to release electrons in order to synthesize ATP and NADPH from ADP and NADP+. In a nutshell, the processes involved in this stage are Electron transport chain, photosystem I, photosystem II, and ATP synthase.

- In the light-independent stage, also called CALVIN CYCLE, the ATP, NADPH, and CO2 are used as reactants to synthesize SUGAR (glucose), NADP+ and ADP (which goes back to the first stage) as products.

Some bacterial cells are resistant to a variety of antimicrobials because they actively pump the drugs out of the cell.
ad-work [718]

True. Some bacterial cells are resistant to a variety of antimicrobials because they actively pump the drugs out of the cell.

A significant resistance mechanism in Gram-negative bacteria is drug efflux. It expel solutes from the cell. Antimicrobials and metabolites are just a few of the hazardous compounds that Efflux pumps help bacteria remove from their interior environments so they can regulate it.

The main efflux systems in Gram-negative bacteria are members of the RND superfamily and typically consist of an outer membrane protein channel, a periplasmic protein, and a cytoplasmic membrane pump. The most common example is  MFS (such as Bmr and Blt in Bacillus subtilis) and the ABC transporters.

Chytrids have some unique characteristics that are different from the other groups of fungi. What characteristics make them uniq
xeze [42]

Answer:

Their spores are produced in sac-shaped structures.

Their spores are produced in club-shaped structures.

Their reproductive cells have flagella.

Their reproductive cells have several nuclei.

They live in wet places.

They live in dry places.

Explanation:

The Chytridiomycota, often called chytrids, are unique among all fungi in having motile stages in their life cycles; no other fungi have this trait. These motile stages take the form of zoospores, single cells with a single posterior (at the rear) flagellum.
