For her science fair project, your little sister replicated one of Mendel’s experiments. From a P0 pea plant with purple flowers and a pea plant with white flowers, she got 1 purple F1 hybrid (she had forgotten to water, so just one survived). From this self-fertilized F1 she got 8 F2 offspring. 7 were purple and 1 was white, for a 7:1 ratio. Did your little sister just disprove Mendel’s laws?
A. Yes. This, and other examples of non-Mendelian genetics demonstrate that Mendel’s Laws are actually incorrect and misleading.
B. No. When another pea pod forms on the plant, that will bring the numbers up to the correct 9:3, or 3:1 ratio
C. No. Dehydrating the parent caused Lamarckian selection on the offspring.
D. No. Random chance can cause deviations in the ratio of small numbers of progeny.

evidence and logical support is essential for a scientist to do in order to maintain credibility. this is because no one can believe without any logic and without any evidence.hence a scientist can maintain credibility by proving himself and by answering logically so experiments prove very beneficial. logical hypothesis give conclusion which is acceptable. therefore, there are two main factors to maintain credibility by a scientist is evidence and logical support.

d. cellulose and starch

essentially, one bacterial cell splits into two daugurer cells. bacterial offspring don't need or get care from their parents because they are in a sense their own parents. that said, some bacteria can and do depend on other bacteria especially in harsh environments such as bacterial microfilms in hot water tanks.
