Another alternative is to attempt to get enrolled in randomised controlled trial (RCT) for the drug which gives you a decent chance of receiving the experimental new agent. It is not assured you receive the drug since there is likely to be a control group receiving a placebo or the best currently available treatment and you could be (randomly) assigned to this group. Such clinical trials have a strong allure for terminally ill patients, and it is known that they will often ‘try anything to stay alive’
However, such a strong willingness of terminally ill patients potentially poses problems. First, it might make the offer or option to participate in an RCT a coercive one that some patients are unable to refuse. This might invalidate free and informed consent [3], although others have argued that this is not necessarily the case [4]. Second, it has been argued that it might even compromise the clinical trial system. Schuklenk (2014), for example, uses the example of AIDS trials in the past and argues that: ‘[Patients] lied and cheated to get into trials and left trials in such large numbers as to threaten the viability of the AIDS clinical trials system.’ ([5]: p.21).
As such, there is increasing attention for other ways to provide terminally ill patients with access to experimental and innovative drugs.

Answer:
Evolution of Polar Bears
Explanation:The fossil transitions leading to our knowledge of development of the Polar Bear species are very well documented. Bear fossils change through time; i.e., as higher levels of sediments and sedimentary rocks are examined, more recent fossils are found.
The observed fossil transitions that inform our knowledge of Polar Bear speciation are very well documented. Bear fossils change through time: generally, when examining the fossil record, successively deeper levels of sediments or sedimentary rocks yield successively older fossils. For some transitions from one species to another, one can find a well-characterized series of transitional specimens leading the observer across the species "boundaries" (Kurten, 1976).

What does it mean to impregnate xylem a cell wall?
Answers
Answer:
The walls of xylem cells are lignified (strengthened with a substance called lignin). This allows the xylem to withstand pressure changes as water moves through the plant.
Explanation:
The xylem transports water and minerals from the roots up the plant stem and into the leaves.
In a mature flowering plant or tree, most of the cells that make up the xylem are specialised cells called vessels.
Vessels:
Lose their end walls so the xylem forms a continuous, hollow tube. Become strengthened by a chemical called lignin. The cells are no longer alive. Lignin gives strength and support to the plant. We call lignified cells wood. Transport in the xylem is a physical process. It does not require energy.

Write a short answer below describing each energy transformation in the diagram which is located
above. For example describe how photosynthesis captures energy in and releases energy out (include
what form of energy). Next describe how cellular respiration captures in and releases energy out (inlcude
in what form.)
Answers
Answer:
Photosynthesis: the plant takes in energy from the sun, converts it into glucose (photosynthesis), and releases energy as Oxygen Gas (O2)
Cellular Respiration: Food is taken in by the organism and process in the digestive system going through aerobic processes and is released by Carbon Dioxide (CO2).
Explanation:
You need Carbon Dioxide to start Photosynthesis including water and sunlight, the process inside the plant undergoes the Calvin Cycle, Carbon Fixation, and Reduction. Plants can also go into fermentation engulfing alcohol or lactic acid (when your muscles are sore after you work out). Oxygen gas is released after carbon fixation turning into pyruvate and is no longer needed to continue the process.
You need Oxygen Gas to start Cellular Respiration. Inside the cells, Glycolysis, Pyruvate Oxidation, the Krebs Cycle, and Oxidative Phosphorylation occur. After the reaction, Carbon Dioxide (CO2) is released from the cells as heat.

Answer:
artificial selection/selective breeding
Explanation:
The illustration is an example of artificial selection.
By definition, artificial selection is the deliberate perpetuation of some traits in living organisms simply because the traits are desirable. The organisms are selected because of the traits and allowed to breed either naturally or otherwise in order to ensure that these traits appear or are even consolidated in the offspring of the breeding.
The offspring from selective breeding are expected to combine the desirable traits of the two parents and thus, appear better than each of the parents.

what are the 4 different bases in dna and how do they pair?
Answers
Answer:
Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.
A pairs with T.
G pairs with C.

A scientist studying the Milky Way galaxy notices a bright light in the sky. What information would she need to prove that the object is a comet and not a star?
Answers
Answer:
She would need lots of info, but some examples are,
A. Whether or not the subject is moving
B. Whether or not the subject disappears after a set amount of time
C. Whether or not the subject is near or far, and if it changes in size.
Explanation:
The correct answer is I and II.
A comet is made up of ice, dust, and small rocks or particles. They revolve around the sun and can be considered a member of the solar system. When they pass close to the sun they get heated due to solar radiation and start to release gases that are initially in the condensed phase. This release of gases produces a glowing tail behind the comet. When warmed up they produce a bright coma which can be of the order of several times the diameter of Earth.

If an animal fossil was found in a rock, what would be the best way to determine its absolute age?
*analyze the rock’s mineral composition
*take X-rays of the fossil and surrounding rock
*compare it to similar-looking fossils that have already been dated
*measure the ratio of a radioactive isotope and its decay product present in the rocks around the fossil
Answers
Answer:
D
Explanation:
Absolute age is defined as the numeric age of fossils.
To identify the absolute age of a fossil, the amount of certain radioactive elements in the rock are measured. When fossils are formed in the rocks, a small amounts of radioactive elements is included in it. The process to identify age of fossil using radioactive elements is known radiometric dating. So, radioactive isotope and its decay product gives absolute age of fossils.
Hence, the correct answer is "D".
