The drug given to the participants in Group A was the clinical trial drug.
After the manufacturing of a drug, the new drug needs to be evaluated before being pushed into the market for population use.
Researchers usually follow three main steps:
Preclinical drug trialsAnimal trials Human clinical trialsDuring the human clinical trials, drugs that have passed animal tests are used for human clinical trials.
This involves the use of two groups:
Group A: A pill containing a new drug known as the clinical trial drug will be given to participantsGroup B: A pill containing NO drug known as placebo will be given to the same number of participants.The results obtained from both grouped would be evaluated. This will give the manufacturer a clear view concerning the new drug, if it is safe and effective in people.

What makes amino acids unique from one another
Answer:
An amino acid is an organic molecule that is made up of a basic amino group (−NH2), an acidic carboxyl group (−COOH), and an organic R group (or side chain) that is unique to each amino acid. ... Each molecule contains a central carbon (C) atom, called the α-carbon, to which both an amino and a carboxyl group are attached.
The R-groups are different and unique
The R group makes amino acids unique from one another. The correct option is C.
What are amino acids?The R group, carboxylic acids, and amine groups are the building blocks of amino acids, which are tiny molecules. They serve as the foundation for proteins. The twenty different kinds of amino acids.
Amino acids are distinct because they contain three groups. It distinguishes itself from others due to its size, form, and membership in the R group. The R group gives the protein a distinctive shape that has a significant impact.
While the rest of the amino acid structure is the same across all types of amino acids, the R group varies. Therefore, the R group can be used to distinguish between amino acids.
Thus, the correct option is C. the R group.

Which system covers and protects the tissues of the body from UV light and from infections due to bacteria and viruses?
Answer:
integumentary system
Explanation:
The integumentary system is an organ system consisting of the skin, hair, nails, and exocrine glands. The skin is only a few millimeters thick yet is by far the largest organ in the body. The average person’s skin weighs 10 pounds and has a surface area of almost 20 square feet. Skin forms the body’s outer covering and forms a barrier to protect the body from chemicals, disease, UV light, and physical damage. Hair and nails extend from the skin to reinforce the skin and protect it from environmental.

Describe the motion shown in the lines
Answer:
Solution
For figure (a)
During interval AB Velocity is +ve, so the particle is moving in +ve direction, but it is slowing down as acceleration (slope of v-7 curve) is negative.
During interval BC Particle remains at rest as the velocity is zero. Acceleration is also zero.
During interval CD Velocity is -ve, so the particle is moving in -ve direction and is speeding up as acceleration is also negative.
For figure (b),
During interval AB Particle is moving in +ve direction with constant velocity and acceleration is zero.
During interval BC Particle is moving in +ve direction as velocity is +ve, but it slows down until it comes to rest as acceleration is negative.
During interval CD Velocity is -ve so the particle is moving in -ve direction and is speeding up as acceleration is also negatived

which of these actions has contributed to the increase of greenhouse gases in the atmosphere?
A) Clearing forests
B) Excessive planting
C) Chopping wood
D) Watering crops
Answer:
A
Explanation:
Trees and other plants absorb carbon dioxide from the atmosphere as they grow. This is converted into carbon and stored in the plant's branches, leaves, trunks, roots and in the soil. Cutting down of trees without allowing them to regrow, the carbon stored is released to the atmosphere in form of carbon dioxide which contributes to as much as 30 percent of global greenhouse-gas emissions.
