Answer:
Gravity?
Explanation:
Or it could be a non contact force.
Answer:
Benefits:
In a lab, scientists can control the conditions according to their research and study. This allows them to focus on a single perspective.
On the other hand, in a natural setting there are complex interactions due to which focusing on a single attribute can be difficult.
Drawbacks:
Ina laboratory experiment, we cannot control every variable which might be having an effect on our concerned subject as compared to a natural setting. This is because lab experiments are performed in a controlled experiment. Hence, there might be difference of results in a lab experiment and nature.
Answer:
The function of the villi and the microvilli is to increase the amount of surface area available for the absorption of nutrients. Each villus has a network of capillaries and fine lymphatic vessels called lacteals close to its surface.
Explanation:
There, the villi and the microvilli increase intestinal absorptive surface area approximately 40-fold and 600-fold, respectively, providing exceptionally efficient absorption of nutrients in the lumen. There are also enzymes (enterocyte digestive enzyme) on the surface for digestion
Answer:
The correct answer:
1. 100 × 35/100 ⇒ 35% of 100 (2nd and 7th)
2. 200 × 25/100 ⇒ 25% of 200 (4th and sixth)
Explanation:
As it is given that and we know that 25% of 200 can be calculated by multiplying the principle value which is 200 to percentage value divided by 100 (100 is whole value).
Similarly, we can found the calculative representation of 25% of 200 and 35% of 100 are only two values that can be put in boxes after the arrow that are:
1. 100 × 35/100 ⇒ 35% of 100
2. 200 × 25/100 ⇒ 25% of 200
