Answer:
A) Traits can be dominant or recessive, and the recessive traits were "hidden" by the dominant ones in the F1.
Explanation:
Mendel discovered the fundamental theory of heredity: that inheritance involves the passing of genes (he called it discrete units of inheritance), from parents to offspring. Those genes are with two alleles in the genotype, one inherited from the father and other inherited from the mother.
When he cross-bred pure-bred parent (always produced offspring identical to the parent) plants dominant traits were always seen in the offspring, while recessive traits were hidden until the first-generation (F1) hybrid plants were left to self-pollinate. Mendel also noticed that in second-generation (F2) of the offspring 3:1 was ratio of dominant to recessive traits.
The correct answer is option:
The peak of the bell curve has shifted to the right, with a greater frequency of crickets with long legs and a lower frequency of crickets with short legs.
The given condition would lead the directional selection of the crickets with long legs. Directional selection leads to shifting of curve in one direction, which is more suitable.
The crickets with short leg get easily caught by predators, so, after sometime, there would be a decrease in number of the crickets with short leg. At the same time, the crickets with long leg would manage to save themselves and their number would comparatively increased.
C. All cells arise form previously existing cells. This is because the scraped knee's cells would be replaced by the exact same ones that were removed. Kind of like "Out with the old and in with the new... yet the exact same..!"
Hope this helps!

<h2>Nuclear Envelope</h2>
Explanation:
- <em>The endomembrane system</em> includes the nuclear envelope, the <em>endoplasmic reticulum, Golgi mechanical assembly, lysosomes, vesicles, just as the plasma layer</em>
- These cell parts cooperate to <em>alter, bundle, tag, and transport layer lipids and proteins </em>
- The nuclear envelope is a double membrane, implying that there are <em>two lipid bilayers</em>
- The nuclear lamina, a netlike cluster of <em>protein filaments, associates the layers of the nuclear envelope</em>
