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:

1. 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").

Answer:

A clade is a grouping that includes a common ancestor and all the descendant species of that ancestor. Clades are differentiated visually based on where they branch off from one another.

Explanation:

A clade is a grouping that includes a common ancestor and all the descendants (living and extinct) of that ancestor. Using a phylogeny, it is easy to tell if a group of lineages forms a clade. Imagine clipping a single branch off the phylogeny — all of the organisms on that pruned branch make up a clade.

Clades are nested within one another — they form a nested hierarchy. A clade may include many thousands of species or just a few. Some examples of clades at different levels are marked on these phylogenies. Notice how clades are nested within larger clades

Answer:

A clade is a monophyletic grouping in which all the organisms stem from the same branching point.

Explanation:

The organisms in a clade must all stem from the same branching point in evolutionary history, as represented in the phylogenetic tree.

Answer:

What effect will that have on the residence time of carbon dioxide in the atmosphere?

Individual Carbon Dioxide molecules will be in the atmosphere for less time as it is rapidly being cleared and produce.

What effect will it have on the total amount of carbon dioxide in the atmosphere?

None, because humans are producing more as they remove it.

Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions. It can have harmful effects on plants, aquatic animals, and infrastructure.

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

Air pollution like sulfur dioxide and nitrogen oxides can cause respiratory diseases, or can make these diseases worse. Respiratory diseases like asthma or chronic bronchitis make it hard for people to breathe.

Acid rain leaches aluminum from the soil. That aluminum may be harmful to plants as well as animals. Acid rain also removes minerals and nutrients from the soil that trees need to grow.

The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes.

Answer:

When rain water has a lower pH(acidic) than usual it is considered acid rain.

Rain water becomes acidic when sulfur dioxide and nitrogen oxides are released into the atmosphere. They cause a chemical reaction with water, oxygen, and other chemical in the atmosphere to form sulfuric and nitric acids which then mix with water and fall down as rain.

Acid rain causes air pollution which can cause respiratory diseases. This can cause difficulty in breathing. Acid rain causes asthma, chronic bronchitis and pneumonia.  

Acid rain removes nutrient from the soil, trees need these in order to be healthy. It separates aluminum from the soil which destroy plant root tips, this makes it difficult for trees to take up water.

Acid rain reduces the pH of water in aquatic systems which is harmful to marine animals. It kills many fish and other creatures that fish eat. It separates aluminum from the soil which drains into water system. The  aluminium is toxic to fish in acid waters. It causes damage to the gill which effects the respiratory system of the fish and the fish dies.

Acid rain is affecting most of the places on earth.

Answer:

C. Disruptive selection

Explanation:

Disruptive selection, also called diversifying selection, describes changes in population genetics in which extreme values for a trait are favored over intermediate values. In this case, the variance of the trait increases and the population is divided into two distinct groups. Two separate groups emerge.

Directional selection most likely to result in speciation. The correct option is B.

Speciation is the process by which a new plant or animal species emerges. When a group within a species separates from other members of its species, it develops its own distinct characteristics.

Speciation is the evolutionary process by which new and distinct species emerge. Species evolve through genetic modification. The new species is reproductively isolated from the previous species, which means it cannot mate with it.

Apple maggot flies - Originally only laid eggs on hawthorn apples, apple maggot flies now lay eggs on both hawthorn apples and other domestic apples in the United States.

The speciation is caused by one of the reason known as directional selection.

Thus, the correct option is B.
