Answer: The most serious of these mutations will be the insertion of 2 bases. Becasue the genetic code is read in triplets, a 2 base insetion will alter the reading frame of the code causing a frameshift mutation meaning every amino acid after the site of the mutation will be incorrect.
Answer:
- Independent variable: Car weight (car + block with a mass of 10 grams)
- Dependent variable: Speed (the time the car takes to descend the ramp)
Explanation:
As you can see in the question above, Shawn wants to check the speed that a car takes when going down a ramp, related to the weight of this case, that is, he wants to know the influence of the weight that the car presents, in its speed in going down a ramp.
In this type of experiment, we can consider the weight that the car presents as the independent variable. This is because independent variables are those that influence a result within the experiment. They happen without the influence of another variable and are factors that impose changes in the analyzed system.
The dependent variable, however, is the car's speed down the ramp. This is because the dependent variables are those that need and are influenced by the independent variable, to achieve a result that can be measured and analyzed.
Answer:
It develops over land and is cold and dry!
Explanation:
It's a continental air mass, so it develops over land! Maritime ones develop over water. It's cold and dry because it's a polar air mass, not tropical!
I hope that helped you!
Answer:
A. Glucose leaves the cell through the GLUT-1 uniporter, traveling down the new concentration gradient.
Explanation:
The Glucose transporter 1 (GLUT1) protein is a critical uniporter transporter that facilitates the movement of glucose molecules across the plasma membrane. The expression of GLUT1 is increased when glucose concentration is reduced and, inversely, GLUT1 expression is reduced when glucose levels are increased. The erythrocytes are cells that continuously require the supply of glucose from the blood plasma, this mechanism involves the function of GLUT1 that permits the energy-free passage of glucose by diffusion.
It was how fast it was disappearing. Once the world's fourth largest lake, the Aral Sea in Central Asia has been losing water for half a century — ever since Soviet engineers began diverting the two rivers that sustain it, the Amu Darya and Syr Darya, in order to grow cotton in the desert.
