It is known as a concentration gradient which in diffusion will always flow from ares of high concentration to areas of low concentrations
So i believe the answer to this is A.
Answer:
Constant variables
Explanation:
Elaina's investigation lacked the critical ingredient of constant variables which are important components of every scientific investigation. In every research, there are 3 important variables, namely:
1. Dependent variables: the actual variable to be measured during the course of investigations and whose values are dependent on another variable (independent variable) supplied by the investigators.
2. Independent variable: one of the variables that are supplied by investigators whose values are often manipulated to see the kind of changes it will cause to the dependent variable.
3. Constant variables: other variables that are neither independent nor dependent but constant for all the various experimental groups in investigations.
Answer: Because according to the universal law of gravitation, the effect of the force of gravity decreases as the distance increases. The gravitation force is inversely proportional to the radius or the distance. So, the gravitational force exhibited by the Mars is not experienced by us due to the large distance.
Explanation:
It should be A. It is universal among all life on Earth.
I wouldn’t genetically engineer my child as this has a lot of ethical concerns as certain people believe that we are created in the image of God so altering that would be deemed as wrong and sinful. Also this may have later health concerns for the child which hasn’t yet been tested so can not be sure if having designer babies is safe or not.
