Embryology, the study of the development of the anatomy of an organism to its adult form, provides evidence for evolution as embryo formation in widely-divergent groups of organisms tends to be conserved. ... Another form of evidence of evolution is the convergence of form in organisms that share similar environments.
Answer and Explanation:
The quality of the data can be higher in observational or experimental studies depending on the subject being researched.
In a way, we can think that experimental studies have better data quality, due to the design of the experiment and the control of the study groups and the variables that are not possible to be established in the obsevational experiments.
However, in the case of studies of abstract subjects, the experimental study ceases to provide high quality activities, and it is necessary to establish an observational study so that efficient data can be promoted.
Answer:
a. allow a variety of molecules to cross the cytoplasmic membrane
Explanation:
The cells have different molecules in its membrane. As a membrane the main function of it is to regulate the income and outcome of substances that the cell needs or the cell has like some wastes.
Some of these molecules can be some proteins like the permeases, that is going to regulate the solutes that can enter the cell, but since they are non specific, that means that can not make the difference among one carbohydrate and another (as an example).
The answer is c) Organisms are multicellular and undergo photosynthesis!
