The endosymbiotic theory which is also sometimes referred to as symbiogenesis states that all the organelles of the eukaryotic cells are prokaryotic cells that tends to live in a much larger host. This theory is important because it does explains how the eukaryotic cells are able to obtain the needed nourishment that is believed to be replenished by the prokaryotic cells.
Answer: Hydroelectric power will be the best energy source.
Explanation:
<u>Solar energy-</u> It refers to the energy that is directly derived from the sun, and are later used to convert into some kind of electrical or thermal energy. For example, solar panels.
<u>Biomass energy-</u> It is a type of energy that are directly obtained from the plants as well as organisms. This can be regenerated again and again. For example, bio-gas and food crops.
<u>Hydroelectric power-</u> It is a type of energy that is collected, from the rapid motion of water. A dam is needed to construct across a narrow river, which will store water as a reservoir. And this water, when allowed to flow then it initiates the movement of the turbines and due to this continuous motion of the turbines, electricity is generated.
Thus, the most efficient energy source for the given area is the hydroelectric energy, that fulfills the condition for setting up dams in the two rivers, which will generate a huge amount of electricity.
The abiotic environment consists of non-living things. So, rocks, temperature and water are part of the abiotic environment.
<h3><u>Answer;</u></h3>
<em>a)9:16 b)3:16 c)3:16 d)1:16</em>
<h3><u>Explanation;</u></h3>
To complete the table;
- EeAA
- EEAa
- EEaa
- eeAA
- eeaa
Unattached earlobes, will either be Ee (heterozygous) or ee (homozygous)
Cleft chin, will either be; AA (homozygous) or Aa (heterozygous)
Attached earlobes will be ee, while no cleft will be aa.
Therefore; <em>the Unattached earlobes and cleft chin = 9/16 </em>
<em>Unattached earlobes and no cleft = 3/16 </em>
<em>Attached earlobes and no cleft = 3/16 </em>
<em>Attached earlobes and no cleft = 1/16 </em>
Answer:
Option (A) and (C).
Explanation:
Greenhouse effect increases the earth's temperature every year. This causes the melting of glaciers and causes flood situation in the plain areas and allows the persistence of harmful gases in the atmosphere.
Greenhouse gases has the ability to trap the heat of the sun radiated by the planet. These greenhouse gases includes carbon dioxide, carbon monoxide, water vapor and methane. These green house gases increases the effect of the greenhouse.
Thus, the correct answer is option (A) and (C).
