The answer is C. This is because, with every mitotic division,
the cell population doubles because each cell gives rise to two daughter cells.
Therefore, mathematically, after 4 division of one cell, there will end up with
16 cells (2^4).
Answer:
Oxidize organic compounds AND use organic compounds as terminal electron acceptors. (Ans. E)
Explanation:
Anaerobes are the organism that does not require oxygen for their growth. The anaerobes are subdivided into three main classes:
1) Obligate anaerobes: These organisms use anaerobic metabolism to grow and killed in the presence of oxygen. Obligate anaerobe examples are Clostridium and Propionibacterium.
2) Facultative anaerobes: These organisms prefer to grow using aerobic metabolism processes and switch to anaerobic metabolism in the absence of oxygen. An example of facultative anaerobic bacteria is Lactobacillus.
3) Aerotolerent anaerobes: These organisms use anaerobic metabolism to grow and can survive in both conditions (oxygen and oxygen-free environment).
Anaerobic bacteria, oxidize organic compounds rather than oxygen & use organic compounds as terminal electron acceptors. Anaerobic bacteria release hydrogen sulfide gas as they decompose algae in the water. This process is also known as Anaerobic Respiration, in which formation of ATP without oxygen.
Answer: D. Current atmosphere CO2 levels would be increasing more slowly.
Explanation: A P E X
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.
Stem cells grown on a hard, rigid surface are biased into differentiating into a bone cell lineage. <span />
