Answer:A plane's engines are designed to move it forward at high speed. That makes air flow rapidly over the wings, which throw the air down toward the ground, generating an upward force called lift that overcomes the plane's weight and holds it in the sky. ... The wings force the air downward and that pushes the plane upward.

what is the function of the Diaphragm
Answer: It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily. Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs. The diaphragm, located below the lungs, is the major muscle of respiration. It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily. Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges.

Scientific experiment has done by testing the particular medicine on an animal and by observing the impact of medicine on the animal as well as the reaction of the animal.
There are mainly three types of scientific experiments and these are the experimental which has been consist of the major level of scientific experimentation. The second type has been known as Quasi- experimental and third type has been known non- experimental study or research.

The human genome project was produced an area of science known as bioinformatics. how is this helpful in sequencing DNA?
Bioinformatics is a subdiscipline of biology/computer science concerned with the acquisition, storage, analysis, and dissemination of biological data. This helps organize and determine nucleotides of a given DNA molecule from known data about biological data through computer sustems.
** The Human Genome Project increased speed of DNA sequencing and lowered the cost. Basically made it more efficent.
Check out Bioinformatics lectures and websites! You will gain a better understanding of how this is helpful for sequencing DNA.

Explanation:
Pea plant clones are given different amounts of water for a three-week period. First pea plant receives 400ml. Second pea plant receives 200ml. Third pea plant receives 100ml. Fourth pea plant does not receive any extra water; the plant only receives natural ways of receiving water. The height of the pea plants is recorded daily. What is the independent variable?
A) the different amounts of water
B) the heights of the pea plant
C) the pea plants
D) the natural ways of receiving water
Answer: The independent variable is the different amount of water. The correct option is A.
Explanation:
A variable can represent age, a person, or an entity that can be measured. In statistics, it is simply defined as an attribute of an object to be investigated. There are different types of variables these includes:
--> Dependent variable and
--> Independent variable.
Dependent variables are simply the variables that are affected by the changes that occurs in the experiment. From the experiment they should include:
--> the height of the plant,
--> the size of the plant,
--> the number of leaves
---> if the plant survived or not (dead).
Independent variable are the variables that are changed in the experiment. A good example from the pea plant experiment is WATER. It is the aspect that is used to alter the dependent variable which is the height of the pea plant. I hope this helps, thanks!
The atomic number of carbon is six, which means that a carbon atom has six protons. Carbon has three
naturally occurring isotopes: carbon-12, carbon-13, and carbon-14. Which of these statements are true
about carbon and its isotopes? Select all that apply.
A. All carbon atoms have six neutrons.
B. All carbon atoms have six protons and six electrons.
?
C. Atoms of all carbon isotopes have either more than 6 electrons or fewer than 6 electrons.
D. Atoms of some naturally occurring carbon isotopes may have six neutrons.
E. Atoms of some naturally occurring carbon isotopes may have twelve neutrons.
Feed
Answer:
B. All carbon atoms have six protons and six electrons.
D. Atoms of some naturally occurring carbon isotopes may have six neutrons
Explanation:
Isotopes are atoms of the same elements having same atomic number but different atomic masses.
Atomic number is the number of protons (or electron number in neutral atoms) present in the atomic nucleus of the atom.
Atomic mass number is the sum of protons and neutrons present in the nucleus of the atom.
Considering the options above from the above definitions:
A. All carbon atoms have six neutrons is false because carbon-12, carbon-13 and carbon-14 has 6, 7 and 8 neutrons respectively.
B. All carbon atoms have six protons and six electrons is true because the atomic number of carbon is 12.
C. Atoms of all carbon isotopes have either more than 6 electrons or fewer than 6 electrons is false because atoms of all carbon isotopes have six electrons.
D. Atoms of some naturally occurring carbon isotopes may have six neutrons is true because atoms of carbon-12 have six neutrons.
E. Atoms of some naturally occurring carbon isotopes may have twelve neutrons is false because none of carbon-12, carbon-13 or carbon-14 have twelve neutrons.

Simple organic molecules combine to make larger molecules. Which statement best describes the disruption of the bond between two carbohydrate monomers? (3 points) Dehydration synthesis will remove water molecules, forcing the bond to break. Energy will be stored in the bond between monomers through hydrolysis. The bond in the complex carbohydrate will be broken due to enzyme activity. The helium and hydrogen atoms in the backbone of the sugar will be broken.
Answer:
The correct answer is - The bond in the complex carbohydrate will be broken due to enzyme activity
Explanation:
Carbohydrates are macromolecules formed by the combined simple monomer subunits to make a larger subunit or chain of molecules. Dehydration synthesis is the process required for the build-up of these larger molecules and for this they require energy.
The hydrolysis reaction is used to break the hydrogen bond of these monomer backbones by the addition of water which releases energy. Complex carbohydrates are digested or the bonds present in between their monomers are broken down due to the activity of the series of the enzymatic reaction.
Answer: The bond in the complex carbohydrate will be broken due to enzyme activity.
