Answer:
The mouse CFTR gene and human CFTR gene encode proteins that can serve a similar function.
Explanation:
CFTR (Cystic fibrosis transmembrane conductance regulator) gene that codes for the membrane protein. This gene is responsible for the transport of the chloride ions in the cell.
Any mutation in CFTR gene can cause the lung diseases in individual. As shown in the experiment the mouse gets normal when given normal human CFTR gene. The CFTR gene plays the similar role and function in both huamn and mouse.
Thus, the correct answer is option (C).
<span>The pressure generated during contraction of the atria is less than that generated during contraction of the ventricles.The reason is the different distance from the artria to ventricles and the distance from ventricles to circulatory system.
</span>The distance from atria<span> to </span>ventricles<span> is </span>less than<span> that from </span>ventricles<span> to circulatory system.</span>
Answer:
The correct answer is option C) "More than one variable is being tested".
Explanation:
One of the basis of scientific experimentation is to test one variable at the time in order to make sure that the response that is being obtained is the result of that variable and not another one that is not taking into account. In this case, the student is making the mistake of assessing two variables at the same time: the use of detergent and placing the plant in the sun or in the shade. At the end of the experiment the student will not know if the response is the effect of the detergent, the exposure to the sun or a combination of both.
Answer: Deoxyribonucleic acid is a molecule composed of two chains that coil around each other to form a double helix carrying genetic instructions for the development.
Explanation:The two strands of a DNA molecule are separated and each is used as a pattern or template to produce a complementary strand.
