Answer:
plants take in carbon dioxide (CO2) and water (H2O) from the air and soil.
Explanation:
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
(if this isnt what your asking just let me know and i do it again)
The answer is b because water has a PH of 1 and lemon juice is very acidic
Answer: natural killer cell
Explanation:
Natural killer cells are referred to as the granular lymphocytes which play vital roles in the immunity against viruses. It doesn't need antigenic activation in order to detect and kill pathogens.
When an enemy cell is present, a natural killer cell secretes perforins, which bore a hole in the enemy cell membrane.
The correct answer is option B, that is, electroporation succeeded by recombination.
A usual method of presenting exogenous nucleic acids into cells is known as electroporation. In this, an electric voltage potential is used through a biological membrane, ultimately resulting in the formation of conducting hydrophilic pores. The process of electroporation is utilized for transporting or transfecting nucleic acids generally DNA within the cells, to make them articulate genes that would modify the genetic mechanism.
The transfected DNA can get recombined or incorporated into the host genome or can remain in its own composition. Thus, the process of electroporation straightforwardly permits more recombination to take place.
B ecosystems because that’s where intraspecific competition occurs
