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
Explanation:
Which process forms fossils?
A. variation
B. adaptation
C. mineralization

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.
