Answers

Answer 1
Lungs
The lungs carry deoxygenated blood to the heart while the arteries take away oxygenated blood
Answer 2

Answer: Blood picks up oxygen primarily in the lungs.

Explanation: The respiratory system refers to the anatomical structures and physiological processes involved in the exchange of oxygen and carbon dioxide between the body and the environment.

Blood picks up oxygen primarily in the lungs. When we inhale, oxygen enters the lungs and diffuses into the tiny air sacs called alveoli. Within the alveoli, oxygen molecules bind to hemoglobin in red blood cells, forming oxyhemoglobin.

This oxygen-rich blood is then carried by the circulatory system to deliver oxygen to tissues throughout the body. The heart pumps the oxygenated blood to the rest of the body, but it is the lungs where the actual exchange of oxygen occurs. The intestines, on the other hand, play a role in absorbing nutrients from digested food but are not directly involved in oxygenation of blood.

Write a paragraph (4-5 sentences) explaining how natural selection and selective breeding are related?

Answers

Natural selection and selective breeding are related because they both involve the process of selecting traits that are desirable. Natural selection is a process that occurs in nature where organisms with advantageous traits are more likely to survive and reproduce, passing on those traits to their offspring. Selective breeding, on the other hand, is a process where humans intentionally breed organisms with desirable traits in order to produce offspring with those traits. Both processes involve the selection of traits that are beneficial and can lead to the evolution of new species or the production of new varieties of crops or livestock.
Natural selection and selective breeding are related in that they both involve the deliberate selection of certain traits in a population. Natural selection is the process by which certain traits become more or less common over time due to their impact on an organism's ability to survive and reproduce. Selective breeding, on the other hand, involves the intentional breeding of organisms with desirable traits, such as high milk yield in cows or short stature in dogs. Both processes involve the selection of traits for their fitness or utility, but natural selection is driven by environmental pressures and survival, while breeding is driven by human desire or need.
