Explanation:
Of the energy that reaches the Earth from the Sun, a small amount is absorbed by the atmosphere, a larger amount (about 30%) is reflected back to space by clouds and the Earth's surface, and most of it is absorbed at the planet surface and then released as heat.
Energy is transferred between the Earth's surface and the atmosphere in a variety of ways, including radiation, conduction, and convection.
Molecules of all substances, even solids, have random motion and therefore an associated kinetic energy and temperature. ... Completely empty space would have no temperature since there are no molecules there.

Answer:
Nephron is the functional unit of kidney. The kidney contains around 4 to 5 million of nephrons in their structure. These nephrons helps in the blood filtration.
The loop of Henley passes down the filtrate for the production of urine. The excess salt is removed from the loop and deposited in the medullary part of the kidney. This is important as the nephron can now become hyperosmotic medullary concentration and helps in the urine production.
Answer:
Option-A
Explanation:
Pentose phosphate pathway is the alternative pathway taking place in both eukaryotes and prokaryotes parallel to the glycolysis.
The pentose phosphate pathway forms the electron carriers called NADPH and the ribose-5 phosphate.
The NADPH is formed in large amounts through this pathway which contains a very high amount of energy. NADPH can donate its hydride ions, therefore, it can be involved in the reaction where it can donate energy in the form of hydrogen and electron.
The NADPH is therefore involved in the formation of reducing biosynthetic pathways like fatty acid synthesis, cholesterol synthesis, and bile acid synthesis.
Thus, Option-A is the correct answer.
Mostly because they are made up of living cells, but in the bigger picture they are not alive.
Answer:
True
Explanation:
The cytoskeleton is a non-membranous organelle. It is a dense network of protein fibers. The main function of the cytoskeleton is to impart cells mechanical strength, shape, and ability to move. The cytoskeleton is highly dynamic as it keeps on constantly changing. Its framework of three types of protein filaments.
These filaments are microtubules, microfilaments, and intermediate filaments. Microfilaments are made up of actin protein while the tubulin protein subunits make the microtubules. Both actin and tubulin are the globular protein. On the other hand, several different proteins together make the intermediate filaments of the cytoskeleton.
