Answer:
An egg placed in salt water will float!
Explanation:
In normal tap water, an egg will sink because it's density is greater than the density of water. But, when salt is added to the water, it's density becomes greater than the egg's density. The term used to describe this is "buoyancy."
Answer:
Homologous structures can be described structures which originate in different organisms from a common ancestor and may or may not have the same functions.
Zeuglodons can be described as ancient whales and Orca is a common whale today known as the killer whale.
<u><em>Scientific studies show that Zeuglodans and Orca have many structures in common such as:</em></u>
- <u><em>Having teeth with two roots</em></u>
- <u><em>The presence of nostrils</em></u>
- <u><em>Pelvis and internal femur bones</em></u>
Answer:
plant cell
Explanation:
1.cell well-protected and provides structural support of cell
2.cell membrane regulates entries and entries of substances within the cell.
3.nucleus stores DNA
4.plastids they store starch help in photosynthesis
5.chloroplast pigment which protect cell
6.vacuole sustain turgid pressure against cell wall
7.mitochrondria provide energy to help break carbs
8.lysosome help with cellular waste disposal
Storing energy because it’s not with the other energy
Answer:
38 ATP
Explanation:
On complete oxidation of one molecule of glucose yields 38 ATP. Break up of energy production is given below:
- During glycolysis 2 ATP and 2 NADH is produced.
- During formation of Acetyl CoA, 2 NADH is produced.
- During Citric Acid Cycle, 2 ATP, 6 NADH, 2 FADH₂ are produced.
Finally during Electron transport chain, reduced coenzymes NADH and FADH₂ oxidised to release ATP. Each NADH produce 3ATP and each FADH₂ produces 2 ATP. Altogether 10 NADH is produced during entire process of cellular respiration which yield 30 ATP and 2 FADH₂ yields 4 ATP. Therefore, on complete oxidation of one molecule of glucose yields 38 ATP.
