the first one is C and i believe the 2nd is D
Answer:
Brassinosteroids are synthesized from phytosterols and they promote plant growth and development by modulating cellular processes (e.g, cell division, elongation, photomorphogenesis, responses to environmental stimuli, etc).
Explanation:
Brassinosteroids are phytohormones similar to steroid hormones. Phytosterols include sitosterol, campesterol, and stigmasterol, i.e., lipid (cholesterol) molecules that form the cell membranes. These polyhydroxylated steroidal phytohormones play a wide range of cellular roles during plant growth, development and immunity. Examples of brassinosteroid functions include plant development, xylem differentiation, responses to biotic/abiotic stresses, reproduction, etc. For example, campesterol, which is a precursor of brassinosteroid hormones, is an integral membrane component that functions during plant embryogenesis by regulating the permeability of cell membranes and by altering membrane-associated proteins, as well as signal transduction pathways.
The correct answer is B. Lithosphere and atmosphere.
Explanation
The earth can be divided into four subsystems that compose it and make it have everything necessary for life to be possible on it. The first is the lithosphere, the name given to the outer and rigid layers of the Earth that are between 10 and 50 km deep. The second is the hydrosphere, the name given to the parts occupied by the oceans, seas, rivers, lakes, and other bodies and currents of water on planet Earth. The third is the atmosphere, the name of the gaseous layer that surrounds the earth and that is held together with the planet by the force of gravity. and finally the biosphere, a layer made up of water, land, and a thin mass of air, in which living beings develop. According to the previous explanation, in a situation that includes the rain produced in the earth's atmosphere and the fall of snow on the earth's crust, the atmosphere and lithosphere are involved, so the correct answer is B. Lithosphere and atmosphere.
