Answer:
El descubrimiento de Ostrom también creó un problema de taxonomía; Debido a que el espécimen de Teyler era más antiguo, tradicionalmente el nombre de la especie crassipes tendría prioridad sobre la litografía (Pterodactylus obviamente no se aplica porque Archaeopteryx no era un pterodáctilo).
Explanation:
A mature seed consists of two essential parts – the seed coat and the embryo. Seed coat: The outer covering of the seed is known as seed coat. The seed coat develops from the integument of the ovules. The seed coat is made of two layers – the outer layer is called the testa and the inner layer is called tegmen.
Answer:
Only options A (first one) reflects the instances with valid experiment or conclusion.
Quality of any experiment depends upon two things reliability and validity. Reliability is measure of regeneration of results every time an experiment is performed under specific conditions.
Validity is measure of accuracy of results of an experiment. It can be check by two ways: internal validity (checks the design of the experiment) and external validity (checks if the conclusion is the real explanation of the phenomenon).
Now, in marine biologist experiment, he concluded the results only after one breeding season. This makes his results unreliable as it might have happened by chance.
Similarly, in cola experiment the taste was only checked by one candidate i.e. Karl. He might have problem in his taste buds. In addition, the temperature of cola can also affects its taste which is not taken care of in the experiment. Hence, it is not the valid experiment.
Similarly. Jeanette could use more plants for her experiment and Robert just followed only one instruction. He didn't perform any experiment.
