Answer:
becuase cell A is not aFFECTED by a normal cell
Explanation:
After Thanksgiving, Kevin and Gamal use the turkey’s wishbone to make a wish. If Kevin pulls on it with a force 0.17 N larger than the force Gamal pulls with in the opposite direction and the wishbone has a mass of 13 g, what is the wishbone’s initial acceleration
Ans.
Sickle-cell disorder is a genetic disorder, which shows defected red blood cells, due to mutation in the genes for hemoglobin protein.
Malaria is common in sub-Saharan Africa region and there, natural selection favored gene for sickle cells, because it might be beneficial to people having sickle cell disease that makes them able to survive in such condition and transmit their genes to offspring.
On the other hand, in those Africans, who moved to United States, where malaria is uncommon or absent, natural selection favored normal, wild type genes, resulting in fewer people with defected sickle cell.
Hence, sub-Saharan African population shows higher percentage of mutated gene for sickle cell as compared to population of United States.
Thus, the evolutionary process behind this difference is 'natural selection.'
the answer is D. Air will move from an area with higher pressure to an area with lower pressure :)
You know that neutrons are found in the nucleus of an atom. Under normal conditions, protons and neutrons stick together in the nucleus. During radioactive decay, they may be knocked out of there. Neutron numbers are able to change the mass of atoms, because they weigh about as much as a proton and electron together.
Definition. The hypothesis accepted to be true if the null hypothesis is rejected based on statistical evidence. Supplement. In the statistical testing of hypothesis, the two rival hypotheses are the null hypothesis and the alternative hypothesis.
