Answer:
green year round
Explanation:
The strengths of the model the student created are it is clearly labeled and shows that oxygen and carbon dioxide is going in which direction.
A model is something that graphically describes any reaction or process. A model is made up of plastic or any solid material with colors. A model is a good way to show any process or work that has to be done at a big pace.
The model shows the movement of gas into and outside the body. The oxygenated blood transfer into the blood and the deoxygenated blood goes into the lungs.
Thus, the student's model has the advantage of being clearly labeled and showing which way oxygen and carbon dioxide are moving.

Chitin is a polysaccharide made up of N - acetylglucosamine .
Fungi cell walls are made of chitin. Chitin is also the major ingredient of the exoskeletons of crustaceans and arthropods. Spiders, beetles, butterflies, lobsters, shrimps and crabs all have chitin in their protective armor.
when intermixed with protein and other pigments, it forms different levels of hardness and a variety of distinct colors. Alone, chitin appears translucent and not hard. In arthropods, it is secreted by epidermal cells.
Answer: A.Caffeine
Explanation:
Caffeine works by blocking adenosine, a neurotransmitter that promotes sleep. This makes us feel more awake and alert. It's the most commonly used psychoactive substance and is found in many everyday items like coffee and medicines.
The actual mechanism of A) Caffeine is to block chemicals that inhibit or slow nerve activity in the brain. Caffeine functions as an adenosine antagonist, meaning it inhibits the adenosine receptors. Adenosine is a neurotransmitter that promotes sleep, so caffeine's effect reduces sleepiness and enhances alertness.
This mechanism allows caffeine to indirectly increase adrenergic activity (energy release), promoting a more energetic state. While caffeine is often associated with increased alertness and arousal, it's important to remember that it's acting primarily by blocking the inhibiting effect of certain chemicals on the brain nerve activity.
It's noteworthy that caffeine, as the world's most widely consumed psychoactive drug, is unregulated, found in everyday items like beverages and medicines, and generally not harmful in moderation.
