Answer:
Bacterial populations employ native defenses against antibiotics that are analogous to the activity of protonophores. These mechanisms disrupt membrane electrochemical gradients that enable bacterial populations to establish subpopulations of drug-tolerant persisters

How does the fossil record support the Theory of Evolution?
Answer:
Fossils document the existence of now-extinct species, showing that different organisms have lived on Earth during different periods of the planet's history. They can also help scientists reconstruct the evolutionary histories of present-day species.

Create a food chain. Choose the biotic factors from the list and move them onto the hotspots marked with circles. BIOTIC FACTORS Trout Algae Herons Minnows Mosquito larvae Regenerate Reset Check
Explanation:
algae(producer)>mosquito lavae>minnows >trout >herons
Algae, Mosquito larvae, Minnows, Trout, and Herons are arranged in the following pattern in a food chain.
What is a food chain?A food chain is an arrangement of organisms where energy flows from through lower organism to higher organism. Each organism in the chain transfers energy to the other organism present at higher order and the flow of energy goes on. Biotic factors, algae, mosquito larvae, minnows, trout, and herons are arranged in the following sequence in the food chain.
Algae are the primary producers in aquatic ecosystems which are eaten by mosquito larvae, which are then eaten by minnows. Minnows are then eaten by trouts. Herons, being the largest predator feeds on the trout.
Each organism in the food chain obtains energy from the organisms present at lower trophic level. However, the energy flow decreases at each trophic level, therefore, the organism at higher trophic level receives the less amount of energy.
Therefore, the food chain is created in the following order: Algae, Mosquito larvae, Minnows, Trout, and Herons.

describe how energy for the photosynthesis reaction is gained by plants (2)
please help
Answer:
Plzzzz answer fast......
The energy for the photosynthesis reaction is gained in the first stage of the reaction.
There are 2 stages in photosynthesis:
The light-dependent stageThe light-independent stageDuring the light-dependent stage, an electron in the molecules of chlorophyll gets excited and gets knocked off as a result of photon absorption. A molecule of water is split and the electrons released replace the one lost by the chlorophyll after traveling through the electron transport chain.
The energy from the traveling electron is used to reduce NADP+ to NADPH while the splitting of water to H and O means that a proton gradient is established between the stroma and the thylakoid lumen of the chloroplast. The electrochemical gradient thus created is used by ATP synthase to generate ATP from ADP.
The two chemicals, ATP and NADPH, are then utilized as energy sources for the light-independent reaction.

What is the importance of heartbeat blood circulation?
Answer:
With each heartbeat, the heart sends blood throughout our bodies, carrying oxygen to every cell. After delivering the oxygen, the blood returns to the heart. The heart then sends the blood to the lungs to pick up more oxygen.

Explain binary fission in amoeba
Answer:
Binary fission is the most common method asexual reproduction employed by amoeba. During this stage, amoeba stops its movement by withdrawing its pseudopodia and forms a spherical shape. The genetic material is divided by the process of mitosis, after the division of cytoplasm follows the division of the nucleus, resulting in two daughter cells which are identical clones obtained by parent cells.
MARK ME AS BRAINLIEST PLEASE
Answer:
Amoeba is a unicellular organism, and just like bacteria, it reproduces through binary fission. After replicating its genetic material through mitotic division, the cell divides into two equal-sized daughter cells. In this method, two similar individuals are produced from a single parent cell
