Answer:
it depends on the type of the cell.
Explanation:
Prokaryotic cells have internal folding of the cell membrane which are responsible for certain functions like respiration. These foldings increase the surface area.
Eukaryotic cells are compartmentalized which is a method to increase the surface area as there are lots of membranes inside the cell across which many processes take place.
In some cells like the ones making the lining of the villi in the small intestine there are folding in the outer cell membrane which also increases the surface area,
Answer:
The presence of smog in the atmosphere and exploitation and burning of coal
Explanation:
The "smog" can be observed as dark low clouds in the cities. These are formed by accumulation of gases such as: CO2, soot, smoke and dust in suspension. If the atmospheric concentration of the main gases responsible for the greenhouse effect that was maintained in 2016 is maintained, the average temperature of the Earth will have risen 1, 3 ° C in 2020 and 3 ° C in 2070.
In the process of using coal, important environmental damage occurs because when burning it releases large amounts of greenhouse gases.
The damage caused by coal combustion is much greater when poor quality fuel is used, because the impurities it contains are converted into sulfur oxides and other toxic gases.
In the production of electricity, about 5 tons per year are used, causing havoc in terms of pollution
Answer:

C. Although
D. For example
<em>Zebra mussels have been known to have a lifespan of six or seven years in the past but recent discoveries have shown that their average lifespan now ranges between one to two years. Hence, the correct word to fill in the gap would be 'Although'. </em>
<em>The correct option is C</em>
The correct answer is chloroplast. If an organism has chloroplasts then it will be an autotroph because it will be able to make its own food by the means of photosynthesis. This is common for plants but there are some bacteria that can photosynthesize as well. If you don't have them you have to feed on other organisms that have energy for you.
