How do RNA's subcomponents affect its properties? (3 points) A. Adenine and cytosine bond with thymine and guanine, respectively, causing RNA to fold into functional units. B. Base pairing occurs within an RNA molecule to give RNA the three-dimensional shape needed for specific functions. C. Deoxyribose and phosphate interact to provide RNA with a backbone to which nucleotides become bound. D. The nitrogenous bases in RNA molecules undergo dehydration reactions to form large biological polymers.
Answer:
B. Base pairing occurs within an RNA molecule to give RNA the three-dimensional shape needed for specific functions.
Explanation:
Ribonucleic acid, known as RNA, is a type of nucleic acid found in living systems. In opposition to the other type of nucleic acid (DNA), RNA is a short single stranded molecule. Both DNA and RNA are made of nucleotides, composed of a phosphate group, nitrogenous bases and a pentose sugar.
The presence of ribose sugar and Uracil base in RNA instead of deoxyribose sugar and thymine base respectively structurally differentiates the molecule from DNA. However, base pairing occurs within the RNA molecule to form the three-dimensional shape of the RNA, which is key to the specificity of its function.

Write some of the special features of feathers
Answer:
Feathers perform a number of functions for a bird:
1) They provide insulation, body temperature of most birds is maintained at around 40 C.
2) Feathers allow for flight.
3) Feathers control what a bird looks like by supplying the bird with colors.
Explanation:
Feathers insulate birds from water and cold temperatures. They may also be plucked to line the nest and provide insulation to the eggs and young. The individual feathers in the wings and tail play important roles in controlling flight. Some species have a crest of feathers on their heads.
Feathers perform some of the functions for a fowl: 1) They offer insulation, the frame temperature of maximum birds is maintained at around 40 C; 2) Feathers allow for flight; 3) Feathers manage what a chook looks as if by way of imparting the chicken with hues.
What is special about birds' feathers?Feathers permit birds to fly, but they also assist them to show off, combining in, living warm, and preserving dry. A few feathers advanced as specialized air foil wing-like shape that produces elevate and drag because of their actions via the air for efficient flight.

Which of the statements regarding enzymes is FALSE? *
Enzymes are proteins that function as catalysts
O Enzymes are specific
O Enzymes provide activation energy for reactions
Enzymes can only be used once
Answer:
Enzymes can only be used once
Explanation:
Enzymes are there forever
Enzymes are the bio-catalysts that play a crucial role in several chemical reactions and metabolic cycles of the body.
The statement for the enzyme that is false is:
Option D. Enzymes can only be used once
The role of enzymes are:
1. The enzymes are the protein molecules, which are made up of long chains of amino acid residues.
2. Enzymes are highly specific because they have different shaped active sites for the binding of respective substrates.
3. Enzymes are the important parts of reactions and are the bio-catalysts. They lower the activation energy for the reactions and fasten the rate of reaction.
4. The enzymes are referred to as catalysts, and thus they are not utilized in the reaction, thus, they can be reused again.
Thus, Option D is false for enzymes.

An experiment was conducted to determine which type of fruit attracts the most fruit flies. Equal sized pieces of apple, pear, and banana were placed in separate containers at different areas around the school. The containers allowed the fruit flies to enter, but the fruit flies were unable to escape. After one day, observations were made by the students. Which best describes an error the students made in the experiment? A) too many types of fruit were used B) fruit flies were unable to escape C) different areas around the school were used D) one day is not long enough for the experiment
Answer:
C
Explanation:
The error that the student made was to place the containers for the different fruits in different areas around the school.
In order to ensure that each contain receives the same treatment, they should have been placed in the same area around the school. Different areas around the school might have varied populations of fruit flies, hence, jeopardizing the result.
The containers should have been subjected to the same conditions in order to ensure an unbiased outcome.
The correct option is C.

In a person with a low platelet level, which process is slower than normal?
A antibody formation
B blood clotting
C oxygen carriage
D phagocytosis
Answer:
In a person with a low platelet level slower the blood clotting than normal
Explanation:
Lower platelets lever is called thrombocytopenia.
Platelets function is to clot the blood when it becomes low then there is no blood clotting.
A person with a low platelet level has a lower rate of blood clotting than the normal rate that is present in Option B. Platelets play a major role in blood clotting and stop blood loss.
What are the different functions of the blood?The blood has different types of cells, such as the red blood cells that take part in oxygen transport, nutrition transport, etc., and the white blood cells that take part in the protection of the body against foreign pathogens. There are different types of white blood cells, such as eosinophils, basophils, and lymphocytes, and these cells have different properties, such as the ability to detect some viruses, parasites, bacteria etc. Platelets are the cell fragments that take part in blood clotting along with other proteins.
Hence, a person with a low platelet level has a lower rate of blood clotting than the normal rate that is present in Option B.

Earth's layers formed because of differences in ______ of the materials.
Answer:
densities
Explanation:
Earth's layers formed because of differences in densities of the materials.
This means, less dense lighter object will be near the top, and the more dense, thicker and heavier stuff is in the core.
Earth's layers formed because of differences in densities of the materials.
What are Earth's Layer?Earth is made up of four distinct layers, from deepest to shallowest, the inner core, outer core, mantle, and crust. All these layers are formed because of the differences in the densities of the materials.
1. The inner core:
The inner core is composed mostly of iron and nickel. The inner core rotates slightly faster than the rest of the planet, which is also much hotter.
2. The outer core
The outer core is made from iron and nickel which is present in liquid form
3. The mantle
The mantle is made up of of iron, magnesium and silicon which is dense, hot and semi-solid.
4. The Crust
The crust is extremely thin, cold and brittle which is compared to what lies below it that is made of relatively light elements
Thus, Earth's layers formed because of differences in densities of the materials.
