DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. The only difference between ribose and deoxyribose is that ribose has one more -OH group than deoxyribose, which has -H attached to the second (2') carbon in the ring. DNA is a double-stranded molecule, while RNA is a single-stranded molecule.
In ecology, the law of conservation of mass is applied by the principle of taking energy from the lower trophic levels and passing it to the higher trophic level by any means.
<h3>What is the law of conservation of mass?</h3>
The law of conservation of mass states that the actual mass in an ecosystem is neither created nor destroyed. Overall remains constant in a system.
In ecology, it illustrates that when an organism is ingested by other organisms, its mass is conserved. Some of the organisms may also be dependent on the waste products like urine and feces to make proteins and other compounds.
Therefore, the energy or mass is neither lost in any form. It simply is taken by other organisms through any means.

Answer:
D
Explanation:
Improve desirable traits and help determine the heritability of a trait.
Answer:
Spongy bone is well adapted to accept stress in many directions, which makes it good for shock absorption
Explanation:
Spongy bone tissue is less compact and always present towards the interior of the bone and is covered by compact bone. Spongy bone tissue has lamellae that are arranged in an irregular pattern. The thin irregular columns of lamellae are called trabeculae.
The trabeculae of spongy bone tissues are precisely arranged along the line of stress. This feature of spongy bones allows them to resist the stress applied from many directions and to transfer the force making them a good shock absorber. The final arrangement of trabeculae is achieved only after the person learns the locomotory movements completely.
