Answer: The correct answer is- Adaptive evolution is a permanent change in a trait.

Adaptive evolution can be described as increase in the frequency of alleles that are beneficial to the survival of an organism whereas decrease in the allele frequency that do not give any importance to the survival and reproduction of organism. It results because of natural selection.

Therefore, it depicts a permanent change in a trait as natural selection acts on the heritable traits of an individual.

Answer and Explanation:

The steps of the scientific method are

1) A question the investigator wants to answer.

2) Antecedents or Previous knowledge about the study object.

3) The goal, which is what the investigator wants to know.

4) The hypothesis that the investigator makes in order to predict what is going to happen.

5)The experiment is performed to answer the question.

6) Results achievement

7) Conclusions where the hypothesis is rejected or accepted.

In the case of the exposed example,

  1. Question: How does the amount of sunlight affect the extent of flower production?
  2. Previous knowledge and antecedents about solar radiation influencing different plant growth and flowering. Information about the species of interest. Other studies or investigations performed in relation to this question.
  3. Objective/Goal: To study the influence of sunlight in flowering
  4. Hypothesis: Too many hours of radiation affect flowering production
  5. Experiment: (Example)

Native species are going to be planted in the garden to observe their growth and flower production at different exposure levels to sunlight. Native species will be planted, as they are used to the environmental conditions and they do not need extra care, as a cultivated species would. More than one individual is needed to ensure their establishment. All the species will be watered according to each species needs and location. Plagues will be equally controlled.

  • 3 native individuals of a herbaceous plant, 3 native individuals of a woody plant, and 3 native grass plants are located in a sunny section that receives straight sun radiation during the whole light hours.  
  • 3 native individuals of a herbaceous plant, 3 native individuals of a woody plant, and 3 native grass plants are located in a sunny section that receives sun radiation during half a day
  • 3 native individuals of a herbaceous plant, 3 native individuals of a woody plant, and 3 native grass plants are located in a  shaded section.

Plants will be grown and the flowering process will be recorded by season in relation to the number of flowers, sizes, quality, and pollinizer visitors which will reflect the amount and quality of nectar.

6 y 7. Every recorded result will be then analyzed to conclude.

"which list contains only vitamins that do not function as coenzymes in energy metabolism?"
galben [10]
The right answer is: vitamin C and choline
Choline (vitamin B4) is the precursor on the one hand acetylcholine (important neurotransmitter and neuromodulator) and on the other hand, the cascade initiated by betaine (intermediate in the biological methylation and precursor of membrane lipids). In this, it is considered, by extension, as an integral part of the family of B vitamins,
Vitamin C protects against cellular aging, is essential for the immune defenses and increases the assimilation of iron of plant origin. It also contributes to the formation of collagen. Its deficiency leads to a disease called scurvy (hence the ascorbic acid name of vitamin C).
