The oil-eating bacteria helped in the removal of Gulf oil spill, but it is not that easy in Arctic region. The Arctic waters also comprise of cold-adapted, oil-consuming microbes. Though, they function at a diminished rate of metabolism in comparison to the warm water species.
In the Arctic Ocean, the ocean currents do circulate, but over a larger surface area in comparison to the Gulf of Mexico, so it would take much more years for the bacteria to come back to the similar location. The cold temperatures also influence the nature of the oil, developing it more viscous and thicker that is tougher for the bacteria to dissociate.
An oil spill in such regions takes even longer to dissociate, as the levels of oxygen in such regions go way down and bacteria cannot live in such conditions easily.
Answer:
cell, tissue, organ, organ system, organism
Explanation:
Answer:
object slows down), the way in which we calculate a drag force will be slightly different. .and “coefficient of drag , is it easy for objects to move through it
Explanation:
Answer:
Thymine
Explanation:
DNA nucleotide bases always attach in specific pairs.
Adenine is always with Thymine and Cytosine is always with Guanine. Here, since one nucleotide is Adenine, we know the other nucleotide is Thymine.
One way to remember this pairing is by this device:
Car in the Garage (cytosine goes with guanine)
and
Apple on the Tree (adenine goes with thymine)
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,
- Question: How does the amount of sunlight affect the extent of flower production?
- 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.
- Objective/Goal: To study the influence of sunlight in flowering
- Hypothesis: Too many hours of radiation affect flowering production
- 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.
