3. The water cycle affects the weather i various ways. For instance, it can help control how and when precipitation is present and without the water cycle the weather wouldn’t work as consistently.
The answer is <span>B. A smaller cell has more surface area than volume.
</span>This is simple mathematics. Let's imagine that cell is spherical.
Now, we have two spheres: one big (with radius r = 5 cm) and one small (with radius r = 2 cm).
The formula for the surface area of the sphere (A) is A = 4 π r².
The formula for the volume of the square is 4/3 π r³.
Now, let's compare two spheres:
Small sphere: Big sphere:
r = 2 cm r = 5 cm
A = 4 π 2² = 50.3 cm² A = 4 π 5² = 314.2 cm²<span>
V = 4/3 </span>π 2³ = 33.5 cm³ V = 4/3 π 5 ³ = <span>523.6 cm³
According to the calculation, the smaller sphere will have more surface area than volume. This can be extrapolated to all shapes, not only spheres, so the </span><span>smaller cell has more surface area than volume.</span>
The hope going forward is that stem cells<span> can also be used as a “renewable source of replacement </span>cells<span> and tissues” to treat common and serious diseases without the need for organ transplants or surgeries</span>
Answer: B
Explanation: the products for cellular respiration are water, carbon dioxide and energy
Answer:
It should be D, rocks beneath Earth's surface are forced toward the mantle.
Explanation:
Metamorphic rocks form when existing rocks are exposed to extreme temperature and pressure
Rocks beneath the surface are forced toward the mantle
This movement increases pressure and heat
