Which process breaks down sugars to make ATP when oxygen is present?
A Anerobic Respiration
B Cellular Respiration
C Glycolosis
D Photosynthesis
Answer:
Cellular Respiration
Explanation:
Cellular respiration converts glucose to ATP, glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation are the phases of cellular respiration, hence option B is correct.
What is cellular respiration?
A glucose molecule with six carbon atoms is split into two pyruvate molecules, each with three, during the glycolytic process.
Glycolysis kicks off the process, a six-carbon glucose molecule is divided into two molecules with three carbons in this initial phase. The molecule with three carbons is known as pyruvate.
Anaerobic (without oxygen) and aerobic (with oxygen) cellular respiration are both possible (without oxygen).
Therefore, during aerobic cellular respiration, glucose, and oxygen combine to create ATP, which the cell may utilize, as byproducts, carbon dioxide, and water are produced, hence option B is correct.

Seafood Watch recommends which seafood _______.
a. to buy or avoid
b. to catch and sell
c. to harvest sustainably
d. is safe to eat
Answer:
a
Explanation:
to buy or avoid
Seafood Watch recommends which seafood to buy or avoid. Thus, option A is correct.
What is seafood?Seafood is food obtained from the sea. Unsustainable fishing methods, such as dragging and dynamite fishing, entrap or kill various species that are not necessarily targeted by the fishing industry. By identifying varieties of seafood that have been caught sustainably, Seafood Watch promotes them over those that have not.
The theory is that since only fisherman who employ sustainable practices are financially rewarded, they will outperform rivals. Based on rigorous scientific standards for environmental sustainability, our Seafood Watch program assigns grades to seafood collected or raised all around the world.
Our suggestions can be used by customers and business owners to locate seafood that has been farmed sustainably. Numerous species are included in the exhaustive list, along with information about where in the water they were caught—from the wild or from farms—and how they were harvested.
Therefore, Seafood Watch recommends which seafood to buy or avoid. Thus, option A is correct.
