Answer:
She didn't use a second fish as a control.
Explanation:
The embryo is under the influence of mechanical stress during its formation, the pressure exerted on a cell contributes to embryogenesis by promoting the expression of a fundamental gene in the differentiation of primitive embryonic tissues such as the mesoderm (one of the layers of the embryo).
Take the example of mesoderm, β-catenin, generally linked to E-cadherin, is a protein involved in cell junctions. A charge of 6 pN exerted on a cell is sufficient to remove the two proteins, thus allowing the migration of β-catenin towards the nucleus where it causes the coding of the mesodermic gene.

Biological classification is the process by which scientists group living organisms. Organisms are classified based on how similar they are. Historically, similarity was determined by examining the physical characteristics of an organism but modern classification uses a variety of techniques including genetic analysis.
Explanation:
hope i could help :)
It’s either A or B. I would probably say A because, In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules and nutrients into organic matter using the oxidation of inorganic compounds or ferrous ions as a source of energy, rather than sunlight, as in photosynthesis. Chemoautotrophs, organisms that obtain carbon from carbon dioxide through chemosynthesis, are phylogenetically diverse. Groups that include conspicuous or biogeochemically-important taxa include the sulfur-oxidizing gamma and epsilon proteobacteria, the Aquificae, the methanogenic archaea and the neutrophilic iron-oxidizing bacteria. Many microorganisms in dark regions of the oceans use chemosynthesis to produce biomass from single carbon molecules. Two categories can be distinguished. In the rare sites where hydrogen molecules are available, the energy available from the reaction between CO₂ and H₂ can be large enough to drive the production of biomass.
