Answer:
B. They cannot reproduce without a host cell.
It is considered to be nonliving as it cannot reproduce on its own.
Explanation:
Without a host cell they are unable to reproduce as it does not have the necessary reproductive tools.
It reproduces by using the host cell's reproductive tools by taking control of it.
Viruses also don't need energy as living organisms do. So the answer may be D. as well.
Viruses are considered to be non-living because they cannot reproduce without a host cell.
WHAT ARE VIRUSES?Viruses are organisms that are incapable of reproducing without a living host.
Viruses can only make use of the mechanism of a living host, which they infect.
Viruses are structurally made up of a genetic material and a protein capsule.
Therefore, it can be said that viruses are considered to be non-living because they cannot reproduce without a host cell.

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.

How is a clade differentiated from another clade
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.

A) Substances are moving rapidly across the cell membrane.
B) ATP is being rapidly consumed near the cellular membrane.
C) Substances are moving from high to low concentrations.
D) Substances are moving through channels in the cell membrane.
Answer:
B) ATP is being rapidly consumed near the cellular membrane.
Explanation:
Active transport is a form of transport used by living systems in which substances/molecules move across a membrane from a region where they are less concentrated to a region where they are highly concentrated. This movement occurs against the concentration gradient, hence it requires energy in form of ATP in order to occur. The transport is said to be "ACTIVE" if it is energy consuming.
Hence, based on the explanation above, the best evidence to showcase the occurrence of active transport in a cell is the rapid consumption of ATP near the cellular membrane. ATP will be used to pump needed substances into the cell via the cell membrane, serving as the semi-permeable membrane.

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").
