Na meteorologia, uma inversão, também conhecida como inversão de temperatura, é um desvio da mudança normal de uma propriedade atmosférica com a altitude. Quase sempre se refere a uma inversão da taxa de lapso térmico. Normalmente, a temperatura do ar diminui com o aumento da altitude.
Answer:
All existing cell are produced by other living cellls
Explanation:
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:
The correct answer is - option C.
Explanation:
CFTR is a short form of cystic fibrosis transmembrane conductance regulator protein which is caused by a recessive mutation in this protein. This mutation results in the accumulation of mucus in secretory organs.
As the disease is a recessive disease, for the mutant phenotype to expressed both copies of the allele required to be recessive.
The mother is negative for the CFTR. Hence, she will not transfer the mutant allele to her child So, the child would have a wild-type phenotype even if the father having two copies of recessive allele.
Thus, the correct answer is - option C.
