- It transports different materials inside and outside of the cell.
- In scientific method, what is the 3rd step?
- This is the variable measured in an experiment.
- Scientific theory is a m_____.
- SI unit of luminous intensity
- SI unit of amount of substance
- One of the earth's spheres where life can exist.
- These type of rocks are formed from cooling of magma.
- Marble is an example of a metamorphic rock which is from l________, a sedimentary rock.
- It is a geological process in which earthen materials are worn away and transported by natural forces such as wind or water.
- It is the process by which unconsolidated materials are converted into coherent solid rock, as by compaction or cementation.
- What enzyme is present in the bacteria, Azotobacter and Rhizobium, which has the capability to combine gaseous nitrogen with hydrogen to form ammonia?
- What is the most abundant gas in Earth's atmosphere?
- It is a cold layer of the atmosphere where temperature generally decreases with increasing altitude.
- It is a layer of the atmosphere where it is wider at the equator than at the poles because the equator is warmer.
- It is the layer of the atmosphere which is warmer at the top than the bottom.
- It is the most external layer of the atmosphere where temperature exceeds 2000C.
- Why is the temperature in thermosphere hot?
- In ecology, it is an area of the planet classified according to the plants and animals that live in it.
- A geocentric view stating that the Earth lay at the center of the universe, with the sun, moon, and known planets, revolving around it in complicated orbits.
- A heliocentric view stating that the Earth and planets rotated around the sun, which is at the center.
- This theory proposes that solar system was formed from nebula cloud, made from a collection of dust and gas.
- It is a ball of frozen gases, rock, and dust; icy body releasing gases as it orbits around the sun.
- It is a rocky object in space which orbits in a belt between Mars and Jupiter in the solar system.
- This happens when the Earth passes between the sun and the moon, casting a shadow on the moon.
- It is an organelle in some plant cells that stores starch and commonly found in starchy plants such as tubers and fruits.
- A thick and rigid membrane in the cell that serves as support and structure; maintains shape of the cell and protects it from external injury.
- What is the difference between cell membrane and plasma membrane?
- It is a semi-permeable membrane present in the cell which regulates the entry and exit of specific substances within the cell.
- This is only found in animal cells where it contains centrioles. It is also where microtubules are made; directs the pole of spindle apparatus.
- Part of the cell where photosynthesis takes place.
- It is a molecule that uses light energy to perform photosynthesis; natural compound present in plants that gives them color green.
- It is a gelatinous liquid inside the cell containing organic and inorganic compounds which holds the different organelles and perform organic functions.
- It is a membranous vesicles stacked upon one another with expanded bulges at their side; sorts and transports molecules for export into plasma membrane or other cells.
- It is a double membrane-bound organelle that serves as site for cellular respiration and provides energy by breaking down carbohydrate and sugar molecules.
- It keeps the nucleoplasm, chromosome, and nucleus distinct from cytoplasm.
- It is an organelle which produces ribosomes and ribosomal RNA.
- It is an organelle which controls the total activity of the cell and contains the genetic material or DNA; serves as site of DNA and RNA biosynthesis.
- These are small organelles composed of RNA-rich cytoplasmic granules that are sites of protein synthesis.
- It is an organelle continuous with the outer nuclear membrane; produces proteins for the rest of the cell to function and contains enzymes responsible for detoxifying substances that gain entry to the cell.
