<span>False. In order to create a control group one must understand the baseline of what is happening. Therefore placebos are given in order to establish this control group. These control groups allow understanding of what an the actual experimental drug, in the case of clinical trials, can do.</span>
<span>1. Planting trees INCREASES THE TRANSPIRATION. The correct option is B. Transpiration is the process by which plants lose water through their openings to the atmosphere. If the number of planted trees increases, the level of transpiration will also increases.
2. INFILTRATION is the process by which water enter deep into the earth surface. Infiltration is a measure of the ability of the soil to allow the water to enter and move through the soil profile.</span>
Answer:
False
Explanation:
During the dissection study the body is kept in laying position so that the scientist can easily perform experiments. The body is kept in laying position not in upward position. The body in upward position will have gravitational effect on the fluids and the body layer will not melt.
Answer:
The probability that both will be Rh-negative out of 99% Rh-positive is 0.01 x 0.01 = 0.0001.
Explanation:
The population contain 99℅ of Rh-positive. This represent almost all of the people.
However, there is still 1℅ chance of having an individual of Rh-negative.
Both of them will have the probability of 1℅ of having Rh-negative(0.01).
Therefore, Pr(Rh-negative AND Rh-negative) = 0.01 x 0.01. The result is approximately equals zero.
The both parents having Rh-negative, will have a dominant Rh-negative blood passed to their children, only recessive Rh-positive of 25℅ chance.
Since the chance of Rh-negative blood passed to their children is 75℅, it is inevitable that their children will be Rh-negative
