The organisms that push carbon to the bottom of the ocean are known as what? Why is this important to the ecosystem?
Answer:
Phytoplankton.
Explanation:
Phytoplankton, which is Greek for "drifting plants" are microscopic, one-celled organisms that drift in the sunlit areas in the oceans and they are key to bringing carbon down into the ocean biological pump from the atmosphere via the process of photosynthesis.
Phytoplankton are super important! They generate about 50% of the atmosphere's oxygen, which is the same amount as all land plants combined. They also form the base of virtually every ocean food web. In short, phytoplankton makes other ocean (and land) life possible.

Sometimes, distinguishing the type of interaction between species in not straightforward. Remoras are fish that are often found attached to larger animals, such as sharks. The relationship between remoras and sharks is often described as a commensalism. Although this suggests that sharks do not benefit from this relationship, remoras sometimes consume parasites on their skin. Which of the statements below best supports the relationship being a commensalism?
Although remoras consume parasites, sharks with remoras show no better health or growth than sharks without remoras.
Although remoras consume parasites, they usually consume the flesh of the shark itself and harm it.
Remoras consume parasites, but sharks depend on parasites to remain healthy.
The fact that remoras consume parasites suggests that they provide a benefit, making this a commensal relationship.
Answer:
The commensal relationship between the sharks and remoras can be described as although remoras consume parasites, sharks with remoras show no better health or growth than sharks without remoras.
Explanation:
A commensal relationship refers to a relationship where two or more organisms in a habitat neither benefit or harm each other.
The second option infers that the remoras harm the sharks. This is a parasitic relationship.The third option infers that the sharks are harmed by the remoras because the sharks depend on something that the remoras are limiting. This is also a parasitic relationship.The fourth option infers a commensal relationship, but falsely describes it. The relationship described by this option is a parasitic relationship (one benefits, the other does not).Therefore, the answer is the first option: Although remoras consume parasites, sharks with remoras show no better health or growth than sharks without remoras.
Answer:
it is A) Although remoras consume parasites, sharks with remoras show no better health or growth than sharks without remoras.

In 1887 a strange nerve disease attacked the people in the Dutch East Indies. The disease was beriberi. Symptoms of the disease included weakness and loss of appetite, victims often died of heart failure. Scientists thought the disease might be caused by bacteria. They injected chickens with bacteria from the blood of a group of chickens that were not injected with bacteria. One of the scientists, Dr. Eijkman, designed a new experiment based on his own observations. Before the experiment, all the chickens had eaten wholegrain rice, but during the experiment, the chickens were fed polished rice. Dr. Eijkman researched this interesting case and found that polished rice lacked thiamine, a vitamin necessary for good health. 1. State the question or problem that Dr. Eijkman investigated. 2. What was the original hypothesis? 3. What was the manipulated (independent) variable and the responding (dependent) variable? 4. Write a statement that summarizes the results of the experiment. 5. How would Dr. Eijkman test his new hypothesis?
When conducting an experiment, you need to have a question or a problem such as what is the cause of the disease. Then, you need to state a hypothesis to make a prediction, like the disease was caused by bacteria. You also need to define the variables involved in the experiment: independent -such as the infected blood used to inject chickens-, dependent -like the chickens response to the infected blood-. Then, according to the results -for instance, the experimental and the controlled groups were equally affected by the disease-, you can accept or reject your original hypothesis. During the experiment there will surge new questions to answer, and new hypothesis to test. In the exposed example, for instance, Dr. Eijkman can test his new hypothesis by injecting bacteria to a group of animals fed with wholegrain rice, and to another group of animals fed with polished rice.
--------------------------------------
When conducting an experiment, there are different aspects to consider, such as the question that drives to the reseach, the hypothesis, theoretical framework, variables involved -independent, dependent, and controll-, methodology, study groups, data analisys, among others.
You need to consider,
• Definition and problem statement. The question for which there is not an answer yet.
• Hypothesis formulation. A hypothesis is a scientific conjecture, not verified, that requires corroboration.
• Data collection and analysis. This step involves testing the observations.
• Results
• Verification of hypothesis. This step involves the deriving of the working hypothesis.
• Discussion and Conclusion.
Available data:
Scientists thought that the beriberi disease might be caused by bacteriaA group of healthy chickens were injected with bacteria and became sickA group of chickens that were not injected with bacteria also got sickBefore the experiment, all the chickens had eaten wholegrain riceDuring the experiment, the chickens were fed polished ricePolished rice lacked thiamine, a vitamin necessary for good health1. The first question made was What is the real cause of the beriberi disease?
2. The original hypothesis was that the disease was caused by a bacteria, and if so, healthy chickens injected with infected blood, would also get the disease.
3. The manipulated or independent variable was the infected blood used to inject the chickens. The responding or dependent variable was the reaction or response of the chickens to the injected blood.
4. Results: Both, the experimental and the controlled group, were equally affected by the disease. Even when the controlled group was not injected with the affected blood, it got the disease too.
5. Dr. Eijkman new hypothesis is that chickens fed with polished rice will get sick because of the thiamine lack. He can test this new hypothesis by injecting bacteria to a group of animals that are being fed with wholegrain rice that has all the necessary vitamins, and injecting bacteria to another group of animals being fed with polished rice that lacks thiamine. If the new hypothesis is correct, the first wholegrain rice group should resist the bacteria attack, while the second polished rice group should get the disease.

Beri-beri is a disease resulting from a lack of vitamin B1 in the human body. This condition occurs, in particular, in people who eat mainly white rice (rice without shell) and some other types of grain crops. In modern society, the disease is rare due to the fact that a sufficient amount of vitamins comes from food.
Vitamin B1 contributes to the normal course of carbohydrate and fat metabolism. Its deficiency leads to the accumulation of pyruvic acid in the human blood and its increased concentration in the nervous system. The consequence of such a biochemical metabolic disorder is damage to the nervous system ("dry beriberi"), as well as damage to the cardiovascular system ("wet beriberi").

What effect will the settling of sediment have on the shape of the stream?
The issue of sediment in aquatic environments has been a topic of concern for many decades. During the nineteen-thirties, erosion became a national issue because of the dust bowl and as a result the Soil Erosion Service was established. Since the nineteen-thirties, the study of sediment erosion, transport, deposition, and intrusion has increased exponentially in the United States. Considering all of the past and current research, it is difficult to focus on essential research, but with limited resources it is imperative to refine the topics and prioritize the necessary areas of study. The same scoping is also true for treatment practices. The best and most effective treatment should be used on the most critical habitat. Establishing this systematic prioritization is a challenging but substantive endeavor.
Answer:
Question was : The graph in part A shows how slow-moving water cannot carry large pieces of sediment. As water slows down on the inside of a curve, some of the larger pieces of sediment will settle out of the water. What effect will the settling of sediment have on the shape of the stream?
Answer:
The river will deposit sediment along the inside of a bend in the river. This deposition causes the inside of the curve to become shallower and move farther inward

As Earth’s climate changes over time, so will its energy budget. One possible effect of a changing climate is changes to cloud cover. If the amount of cloud cover on Earth were to decline, what effect could that have on the amount of energy absorbed by land and oceans?
Answer:
The amount of energy obsorbed by the ocean and land would increase.
Explanation:
Clouds reflect energy from the sun back into space. If there is more cloud cover than there is less energy reflected therefore more is obsorbed.
Answer:
Of the Sun’s energy, 23% is either reflected or absorbed by clouds. If cloud cover declined, the amount of energy absorbed by land and oceans would increase.

What alternate form of genes do nucleic acids have that allows them to offer variability allele codon nucleotide chromosome
Answer:
The options to this question are:
A) allele
B) codon
C) nucleotide
D) chromosome
The answer is A) allele
Explanation:
RNA and DNA are the two nucleic acids in living organisms used for transferring and storing genetic information. Deoxyribonucleic acid (DNA) is the genetic material in living organisms that contains segment coding for useful products/proteins and transmits genetic information from one generation to another. These segments are called GENES.
However, genes contain an alternate form responsible for genetic variation in the traits coded for by them. These alternate or variant form of a gene is called ALLELE. In a diploid organism like human, each trait is encoded by genes which contain contrasting pair of alleles that allows variation for that particular trait i.e. two alleles for each gene. For example, height trait in humans are encoded by gene, which possess two alleles; one coding for short variety (t) and the other for tall variety (T).

Answer:
ttrace
Explanation:
A trace fossil is evidence of an organism, but is not made of the organism itself.
What is Trace fossil?The structure and behaviors of an organism, rather than its physical form, are used to classify trace fossils. A few of the trace fossils discovered in Denali have been connected to body fossils discovered in rocks from the North Slope or Talkeetna Mountains that are of a comparable age.
These connections provide investigators access to identities that are more certain than those known solely from trace fossils.
Bird tracks near probe marks in the earth suggest that the birds were using their beaks to dig for food. Invertebrate burrows located in the same rocks possibly provide the answer to what good food the birds were eating.
Therefore, A trace fossil is evidence of an organism, but is not made of the organism itself.

Option 2, or B
Explanation:
The most practical data would be global temperatures during the 37+ year time period to coincide with the thinning sea ice. Option #1 is far too broad to include (daily), as is option #3 (monthly). The last option is basically proposing to duplicate what the graph already shows.
The additional data that could be used to support or refute the theory of global climate change is as follows:
A graph providing data on average global temperatures from 1980 to 2010.Thus, the correct option is B.
What is Climate change?Climate change may be defined as the long-term shifting or alteration in the average temperatures and weather patterns.
The graph given below illustrates the average temperature from 1980-2010. It is not possible to represent the daily or monthly average temperature of approximately 30 years.
