Answer: B) energy released from exergonic reactions.
Explanation:
Cell metabolism is the set of reactions that occur in the cellular environment to synthesize or degrade biomolecules to produce energy. Synthesis metabolism of biomolecules is known as anabolic (anabolism) and catabolic degradation (catabolism).
Endergonic reaction (product has more energy than reagents) and requires energy to occur. Anabolism occurs when the cell has sufficient energy or substrate. Catabolism, in turn, occurs in situations in which the body needs energy, such as between meals and fasting.
The reactions of anabolism and catabolism are opposite but occur in an articulated manner, allowing the maximization of available energy. Thus, while catabolism occurs spontaneously, an exergonic reaction with ATP production, anabolism is non-spontaneous, or endergonic, requiring energy to occur. In other words energy that drives endergonic reactions is often obtained from B) energy released from exergonic reactions.
Answer:
Vacuum
Explanation:
A vacuum is usually defined as a space in which there is an absence of matter. It can also be said that there is an extremely low amount of pressure due to which the particles present in it are not affected by any type of process that occurs in space. The value of pressure is lower than the value of normal atmospheric pressure.
For example, sound cannot travel in space because there is no medium such as water and air through which the sound waves can propagate.
These viral particles, also known as virions, consist of two or three parts: the genetic material made from either DNA or RNA, long molecules that carry genetic information, a protein coat, called the capsid, which surrounds and protects the genetic material.
Answer:
Birth, growth, reproduction, and death
Explanation:
All organisms are offsprings(birth)
All organisms grow(growth)
All organisms reproduce(reproduction)
All organisms eventually pass away(death)
