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.

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.

An allele that occurs in the gametes of an organism will most likely be transferred to which of the following?
O The offspring of the organism
O The mating partner of the organism
The siblings of the organism
O The other organisms living nearby
NEED HELP ASAP !!!! Thank you
Answer:
The offspring of the organism
Explanation:
The alleles of two mature gametes swap and mix during the reproduction process. Allowing for expression of certain more dominant or recessive traits in an offspring. An offspring contains a mix of allele say Aa from aa, AA parents alleles.

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.

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.
