"<span>b. the liver is able to manufacture some amino acids from others."
The liver has the capability to transform some amino acids into others (called non-essential because they can be produced by the body and there is no need to get them from food). This is done by transamination. Transamination is the process of transferring an amino group from one molecule to another without forming ammonia thanks to enzymes that are called transaminases and preform such transfer.</span><span>

Answer:
A.) Prophase I
Explanation:
Crossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I. By meiosis II, only sister chromatids remain and homologous chromosomes have been moved to separate cells.
Answer:
1.The eyes, a sensory organ, see the ball.
2.Sensory nerves transmit the information to the brain.
3.The brain processes the information.
4.The brain sends signals to the motor nerves.
5.Motor nerves carry the signal to the hand muscles.
Explanation:
When we receive a stimulus by any of our 5 senses (sight, touch, smell, hearing or taste) our body will react to this. Once that the stimulus is received ( in this case seeing the ball) a signal is send through the sensory nerves to the brain. In the brain the information will be processed and an answer will be given through the motor nerves in order to move the muscles and catch the ball. All this process is made in seconds.
By definition, an arthropod is an animal that is invertebrate and has an exoskeleton also known as an external skeleton. In addition they have a jointed appendages. Other characteristics include segmented bodies, open circulatory systems and bilateral symmetry. Based on this we can say that from the list given we can select "endoskeleton" "jointed appendages"
