Answer:
Cell respiration requires oxygen and glucose. Cellular respiration can be described as a process in which organisms convert sugars such as glucose and oxygen into water and carbon dioxide. A huge amount of energy in the form of ATP is generated through this process. This ATP is used by almost every cell of an organism to carry out its normal activities like metabolism, growth etc.
The oxygen used in cellular respiration usually arises from the atmosphere. Glucose comes from the food that an organism eats.
Answer: A). Volcanic eruptions change the pH and temperature of the ocean.
Explanation:
Volcanic eruption from an oceanic floor likely to release gases, sediments which can be of high temperature. The sediements will increase the turbidity in the water and will change the pH and the high temperature may not be tolerated by plants and animals. This may be the result of extinction of many species of marine ecosystem.
Answer:
Sister chromatids are a pair of chromosomes inherited from each parent, while homologous chromosomes are the two parts of a chromosome.
Explanation:
Plant cells contain chloroplast which contain a light trapping pigment chlorophyll. Inside the chloroplast are organelles that functions the work of the chloroplasts. These are stroma, chlorophyll, thylakoid. Stroma is the aqueous space that surrounds the chlorophyll containing membrane of the chloroplast.
Answer: A) Move the fulcrum rock closer to the boulder
Explanation:
The longer the effort arm is and the shorter the load arm is, the less energy it takes to move the end of the load arm.
X <-load effort-> X Effort Energy: 10
____________________
O <- fulcrum
X <-load effort-> X Effort Energy: 100
____________________
O <- fulcrum
