Plants showing hydrotropism grow in response to water.
Answer:
The correct answer is - the phenotypic ratio would be 9:3:3:1.
Explanation:
The two traits that are dominant are free earlobe and straight thumb that are denoted by the E and T on their alternative recessive alleles attached lobe and hitchhiker thumbs denoted by the e and t respectively. The heterozygous condition will be EeTt.
The cross between EeTt and EeTt will produce gametes ET, Et, eT, and et by each. The phenotypic ratio of the cross would be 9:3:3:1, which means 9 out of 16 offspring will be dominant in both trait, 3 will be free lobe and hitchhiker thumb, 3 will be straight thumb and attached earlobe, and 1 will be recessive in both traits. For the cross please check the attached image.
Thus, the correct answer is - the phenotypic ratio would be 9:3:3:1.

Answer:
Robert Hooke main contribution is the discovery of cell.
Explanation:
Robert Hooke (1635-1703) is an English physicist. he was the first man who discovered cell by analyzing the cork. This discovery of cell leads the way for future knowledge about the structure of all living organisms. The contributions of Matthias Schleiden was that he was the first man who analyze the structure of plant cell while on the other hand, Theodore Schwann analyze the animal cell and proposed cell theory from that.
