Answer:
Its basically like a climate zone it has a specific terrain and weather
Explanation:
Archimedes was an ancient Greek mathematician and inventor. He made mathematical discoveries as he solved everyday problems. He invented machines to move heavy objects, carry water, and fight battles. Archimedes recorded his discoveries so that others could learn from them. Today he is considered one of the greatest mathematicians of all time.
Archimedes was born in the Greek city-state of Syracuse, Sicily, in 287 bc. His father, Phidias, was an astronomer. Archimedes also studied astronomy.
It is believed that Archimedes visited the famous library of Alexandria, Egypt, where he met great scholars. While in Egypt, he is said to have invented a machine to carry water upward from one level to another. The machine, known as Archimedes’ screw, is still used in parts of the world today.After studying in Alexandria, Archimedes returned to Syracuse. He wrote many works to explain his discoveries. Archimedes’ most-famous ideas include his explanations of how levers and pulleys can lift and move heavy objects. Another idea, called Archimedes’ principle, is a scientific law. It describes what happens when an object floats in water.
In 213 bc Romans attacked Syracuse. Archimedes invented machines to defend the city. When Syracuse was finally overtaken, Archimedes was killed there in 212 bc.
<h2>d) option is correct </h2>
Explanation:
The stringent response occurs in response to low energy store
For example when there is low level of lactose it means energy level is low so there will be no transcription of genes and hence transportation and catabolism of lactose will be inhibited
When E coli is grown in mixture of both glucose and lactose, at high glucose concentration the growth rate is maximum and lactose catabolism is repressed, this called as catabolite repression and it is due to level of cAMP
Rodenticide because it has the word "rodent" meaning, a mammal of the order Rodentia, which mice and rats are included in. Therefore, the answer is rodenticide.
Answer:
4. transforming the energy in glucose and related molecules in a chemical form that cells can use for work
Explanation:
Glycolysis breaks down glucose into two molecules of pyruvate which is transformed into acetyl CoA to enter the Kreb's cycle. Kreb's cycle breakdown the acetyl CoA into CO2 and H2O. The energy stored in the glucose molecule is released during glycolysis and Kreb's cycle. The released energy is stored in the form of NADH and FADH2 as well as in few molecules of ATP.
The NADH and FADH2 enter the final step of cellular respiration, the oxidative phosphorylation. Here, NADH and FADH2 are oxidized with the help of electron transport chain (ETC). During the transfer of electrons through ETC, the proton motive force is generated which then helps in ATP synthesis.
Hence, the three steps of cellular respiration (glycolysis + Kreb's cycle + oxidative phosphorylation) retrieve the energy from nutrients such as glucose and store it in the form of ATP. ATP is used by cells as an energy source for various other functions.
