The answer is c. oxygen.
Cellular respiration includes glycolysis, link reaction, Krebs cycle, and electron transport chain (ETC), in that order. The main function of ETC is a production of ATP. In this series of oxidation-reduction reactions, electrons from the previous stages of cellular respiration are taken and transported to the oxygen which is the final acceptor of electrons. As the result, water and ATP are produced.
The choices can be found elsewhere and as follows:
1.are soluble and can easily pass through cell membranes
<span>2.contain long chains of amino acids and fatty acids </span>
<span>3.contain atoms of carbon, hydrogen, oxygen and nitrogen </span>
<span>4.are a direct result of dehydration synthesis
</span>
I believe the correct answer is option 1. When most proteins, fats, and carbohydrates are digested completely, they are converted to end products that are soluble and can easily pass through cell membranes. So as to distribute the nutrients needed in different parts of the body.
Magnetic- A non contact force that is generated between charged objects
Electrical- A non contact force that is generated between moving charges
Gravitational- A non contact force that exists between objects with mass
Contact- A force that requires physical contact between objects
i believe this are correct :)
Answer:
There's no eclipse at every full moon and new moon because the moon's orbit is inclined to Earth's orbit by about five degrees. Most of the time, the sun, Earth and moon don't line up precisely enough to cause an eclipse.
Explanation:
During a lunar eclipse, Earth comes between the Sun and the Moon, blocking the sunlight falling on the Moon. Earth's shadow covers all or part of the lunar surface.
