When the data in an investigation does not support the original hypothesis, you can modify your hypothesis to support the experimental data. However, you should NEVER change your experimental data to fit your hypothesis.

The hypothesis is an educated, which is based on the researches done in the past and are well established. The hypothesis is a guess, which is testable. The experiments based on the hypothesis are performed and the data is collected. In case, the data obtained from the experiment does not match the hypothesis then the hypothesis may not be valid, hence, the hypothesis needs a revision in such cases.

Stels [109]

Answer:

D)the sexually reproducing species

Explanation:

  • Sexual reproduction is a mode of reproduction in which two parents are required to generate an offspring.
  • As this mode of reproduction requires two parents, the genetic composition of the offspring is a mixture of both the parents and hence, sexual reproduction gives rise to genetic variation.
  • Genetic variation is essential to survive in a changing environment as it can lead to the development of certain characters that prove to be essential for survival.
  • Therefore, if there are 25 different species of protists in the tide pool, it is the sexually reproducing species that will be able to thrive in the changing environment as their offsprings will have genetic variation and this may lead to a positive natural selection.

A population of lizards lives in a rocky area next to a desert. Some lizards are light colored and blend into the sand. Others a
hjlf

Answer:

c. They may evolve into two separate species as a result of disruptive selection

Explanation:

Disruptive selection is a type of natural selection wherein some extreme change in the surroundings favor two distinct phenotypes while trimming off the mean. Here, the environmental conditions favor more than one phenotype. In the given example, disruptive selection would favor the light-colored lizards in the sandy region while the dark-colored would be favored in rocky regions due to their respective survival success.

With time, these two populations would accumulate more variations and reproductive isolation would not allow them to interbreed and thereby two distinct species of lizards would evolve.

Gekata [30.6K]

Answer:

Drawing of the structure of compounds showing atoms.

Explanation:

Making structure of the compound is the easiest way to show the atoms present in the compounds or to express chemical formula of the compound because in the structure the atoms from which the compound is formed is clearly shown so draw the structure of the compound is the best and quick way to show the chemical formula of the compound.
