Bacteria is a unicellular organism which can multiply very fast by binary cell division.
To get a number of divisions required for cell division: you can use the formula: 2
= number of bacteria
To get 256 bacteria:
2
= 256 (you can solve this equation by a calculator)
so:
n = 8 generations
With this formula the first bacteria is taken into consideration since 1 bacteria gives two, then the two give four, then eight, 16...
Because carbon dioxide is a GREENHOUSE GAS, it can trap the sun's heat in the atmosphere. Because the factory is made of concrete, it may deplete groundwater levels over time by not allowing water to INFILTRATE.
Greenhouse gases (GHGs) are gaseous components that absorb the infrared radiation emitted by the earth's surface and contribute to the greenhouse effect. The increase in their concentration in the Earth's atmosphere is one of the factors causing global warming.
Concrete does not allow water from the ground surface to infiltrate to underground.
Answer:
1. Location: Histosols are the soils which are found in the grasslands, swamps and marshes, whereas the aridosols are soils that are found in desert regions.
2. Color: Histosols are soils which are rich in organic matter therefore, are dark colored, whereas the aridosols are soils that lack organic matter, hence are light in color.
3. Water retention capacity: Histosols exhibit higher water retention capacity as compared to the aridosols.
4. Rate of decomposition: Rate of decomposition is higher in the histosols as compared to aridosols.
Answer:
1. Metaphase II - Chromosomes are lined up by spindle fibers.
2. Telophase II - Nuclear envelope forms around each set of DNA.
3. Anaphase II - Sister chromatids are pulled apart.
4. Prophase II - Centromeres move toward the poles of the cell
Explanation:
<em>Water has unique chemical characteristics in all three states—solid, liquid, and gas—thanks to the ability of its molecules to hydrogen bond with one another. Since living things, from human beings to bacteria, have a high water content, understanding the unique chemical features of water in its three states is key to biology.
</em>
<em>In liquid water, hydrogen bonds are constantly being formed and broken as the water molecules slide past each other. The breaking of these bonds is caused by the energy of motion (kinetic energy) of the water molecules due to the heat contained in the system.
</em>
<em>When the heat is raised (for instance, as water is boiled), the higher kinetic energy of the water molecules causes the hydrogen bonds to break completely and allows water molecules to escape into the air as gas. We observe this gas as water vapor or steam.
</em>
<em>On the other hand, when the temperature drops and water freezes, water molecules form a crystal structure maintained by hydrogen bonding (as there is too little heat energy left to break the hydrogen bonds). This structure makes ice less dense than liquid water.</em>
