Answer:
C. when a portion of the moon passes through the earth's umbral shadow.
Explanation:
A partial lunar eclipse occurs when the Earth passes between the sun and moon but the celestial bodies are not arranged in a straight line. When that occurs, a small part of the moon's surface is covered by the darkest, central part of the shadow of the Earth called the umbra. The rest is covered by the outer part of the shadow, termed penumbra.
The mistake made by the student is that animals do not release carbon dioxide into the atmosphere during respiration.
<h3>Carbon cycle</h3>
The carbon cycle is a cycle which describes the process in which carbon atoms are continually recycled between the atmosphere and the earth.
<h3>Processes that release carbon into the atmosphere include:</h3>
- respiration
- burning of fuels and wood
- emission from vehicles and industries
- death and decay of living organisms
<h3>Processes that remove carbon from the atmosphere include:</h3>
- photosynthesis
- uptake by oceans
- incorporation of carbon into animal shells
Therefore, the mistake made by the student is that animals do not release carbon dioxide into the atmosphere during respiration.

Answer:
D. there is less structural carbohydrate.
Explanation:
Most bacterial cells have a cell wall located outside the plasma membrane, formed by peptideoglycan or murein, which provides protection and shape to the cell. In addition to the wall, some bacteria have a polysaccharide capsule that surrounds this structure, this capsule is a carbohydrate envelope that can allow more or less flexibility to the bacterial cell. The more structural carbohydrates the polysaccharide capsule has the less flexible the bacteria will be. Thus, we can say that if E. coli has the most flexible cell envelope, compared to the envelope of other bacteria, it is because there is less structural carbohydrate in the E. coli envelope.
