The Earth comprises many spheres of subsystems, which associate with each other to develop a composite and spontaneously changing system of the Earth. The processes taking place in the system of the Earth occurs on spatial scales changing from fractions of millimeters to thousands of kilometers, and on time scales, which varies from milliseconds to billions of years.
The examples of instantaneous scales are a rotation of the Earth, breathing, an earthquake.
The examples of long-term scales are making coal and plate tectonics.
The system of the Earth is featured by various overlapping cycles in which matter is recycled again and again. The cycles involve interactions between multiple spheres and systems. The examples of cycles are rock cycle, day and night, and seasons.
Volcanoes discharge a huge concentration of particulate matter into the atmosphere. These particles function as nuclei for the development of droplets of water (hydrosphere). The rainfall, that is, hydrosphere usually upsurges after an eruption, initiating growth of the plant (biosphere). Thus, volcanoes and volcanic activities are a good illustration of system interactions.
The answer is B. CO2 + H2O + Sunlight ----> Glucose + O2
Answer:
chloroplast: makes food for plant cells, photosynthesis
mitochondria:produces energy the cell needs to carry out its functions; release energy
vacuole: stores food, water, and waste
lysosome: found mainly in animal cells, digests old cell parts
endoplasmic reticulum: carries proteins and other materials from one part of the cell to the other
cytoplasm: gel -like fluid where the organelles are found
nucleolus: makes ribosomes, center of the nucleus
ribosome: makes proteins
cell membrane:controls
Explanation:
I'm pretty sure the answer is D based on the info above,and because its the only one that has the correct information about the cell parts
hope its correct
Answer;
Complementary base pairs;
- Adenine-Thyamine and Guanine-Cytosine (A-T and G-C)
Explanation;
-According to Chargaf's rule, the secondary structure of the DNA requires that every guanine pairs with a cytosine and every thymine pairs with an adenine, resulting in consistent ratios between the nucleotides.
-In double-stranded DNA, two long molecules twist around one another in a double helix. Pairs of nitrogenous bases are set in the same plane, and interact with each other via hydrogen bonding. These pairs are often referred to as base pairs
