The oceans cover 71 percent of the Earth's surface and contain 97 percent of the Earth's water. Less than 1 percent of the Earth's water is fresh water, and 2-3 percent is contained in glaciers and ice caps. The oceans contain 99 percent of the living space on the planet.
<u>Answer:</u>
In comparing stop-transfer and internal start-transfer sequences in proteins, it can be said that both are hydrophobic.
Option: (b)
<u>Explanation:</u>
- Hydrophobic means repelling water.
- Hydrophobic molecules are non polar i.e. that there is no static electric field produce by atoms of molecules.
- Due to this reason the hydrogen cannot form hydrogen bond with the molecules.
- Internal start- transfer process is a transfer process of peptide and moves through the side opening of translocon and the anchor itself in the 'membrane'.
- Stop-transfer sequences in proteins halts the 'process of translocation' and moves out through the 'side opening in translocation' to anchor.
Answer:C) chloroplasts and mitochondria
Explanation:
The structure that is responsible for releasing energy from food molecules in some singled celled organisms is MITOCHONDRIA.<span> The major function of mitochondria is to carry out cellular respiration, which make energy available for the cells to use. The mitochondria is also called the power house of the cell, because it is the organelle that specializes in turning the food molecules into the energy form that is usable by the cells.</span><span />
Nucleic acids: Stores and transfers info.
Carbohydrates: Store energy, provide fuel, and build structure in body, main source of energy, structure of plant cell wall.
Lipid: Insulator and stores fat and energy.
Protein: Provide structural support,transport, enzymes, movement, defense.
