which of the following determines the identity of an element?
a. atomic number
b. mass number
c. atomic mass
d. overall change

Answers

A. The atomic number

The identity of any element is given out by the atomic number it carries thus every element has different atomic number. The correct answer is option A.

What does atomic number signify ?

It signifies the number of electrons and the number of protons which are present in any element as the atomic number is equal to the number of electrons and the number of protons as well.

Atomic number is a unique property that is given out to element where the basis of their characters and the properties signifies their basic characters on which the elements will align themselves for example the elements having the atomic number as the 1 at the end usually has 1 electron in their last atomic shell same for 2.

On the basis of their properties elements are divided into various groups where the 1st one is called as alkali metal and the 2nd one is called as alkaline earth metals, 17 is called as halogens and the last 18th is called as noble gases.

Passive transport into cells is driven by a concentration gradient; a greater concentration of molecules on one side of the membrane.

Which direction would oxygen move across a cell membrane if there was a greater concentration of oxygen molecules on the inside of the
membrane?

A. It would continue to concentrate inside the cell.
B. The random diffusion of oxygen would balance and have no net effect.
C. Towards the outside of the cell.
D. None of the above.

Answers

Answer:

A. It will continue to concentrate inside the cell.

Explanation:

Due to the higher concentration of oxygen molecules on the inside, oxygen molecules of the outside move to the inside and the more the oxygen molecules move inside the higher the concentration of the oxygen molecules on the inside.

Answer:

A

Explanation:

Towards the outside of the cell.

what is the difference between runoff and the storage of water?

Answers

Runoff is nothing more than water "running off" the land surface. Just as the water you wash your car with runs off down the driveway as you work, the rain that Mother Nature covers the landscape with runs off downhill, too (due to gravity). Runoff is an important component of the natural water cycle.

Why does the amount of protons and electrons stay the same in stable atoms?

Answers


When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral.

Which best explains how green plants absorb energy from the sun?


A) Sunlight heats up the outside of a leaf


B) Chemical Bonds in a glucose are formed


C) A photon strikes electrons in special molecules in a cell


D) Carbon dioxide combines with water to form glucose molecules.

Answers

Answer:

the answer is C

Green plants absorb energy from the sun when "A photon strikes electrons in special molecules in a cell"

Green plants are unique organisms being that they possess the ability to capture and utilize energy from the sun. This is possible because they possess special pigments in their CHLOROPLAST called CHLOROPHYLL. The general process whereby green plants capture and utilize sun's energy is called PHOTOSYNTHESIS.

During photosynthesis, a photon of light strikes electrons in the thylakoid lumen of the chloroplast. This facilitates the synthesis of ATP (energy) in further reactions that takes place in the chloroplast.

Therefore, green plants are able to obtain energy from the sun when photons (beam of light) strikes electrons in their CHLOROPLAST.

What are sex chromosomes? What is the sex chromosome combination for human males and females?

Answers

Answer:

(Wow! Weird how this pooped up, I just finished this biology lesson.)

Sex chromosomes are the gene that decides on our gender. The males have X and Y sex chromosomes (XY). Females have only two  X sex chromosomes (XX).

More info: Because males have both X and Y sex chromosomes, their genes decide the offspring's gender.

Answer:

The sex chromosomes are referred to as X and Y, and their combination determines a person's sex. Typically, human females have two X chromosomes while males possess an XY pairing. This XY sex-determination system is found in most mammals as well as some reptiles and plants

Whales and dolphins are mammals and breathe air into their lungs, just like we do. They cannot breathe underwater like fish can as they do not have gills. ...

How many water (H2O) molecules could you line up end to end in a nanometer?

Answers

Answer:Molecules have size and different molecules are different sizes. When talking about the size of a molecule, most scientists will mention its molecular weight. That is the total weight of all of the atoms in the molecule. So water, which is made up of two hydrogen atoms (1 atomic mass unit each) and one oxygen atom (16 atomic mass units) has a molecular weight of 18 (well, 18.01528 to be exact). Glucose has a molecular weight of 180. DNA, which is very long, can have a molecular weight that is around 1010 (about the weight of one human chromosome).

I and m are parallel to each other Bit transmission errors between computers sometimes occur, where one computer sends a 0 but the other computer receives a 1 (or vice versa). Because of this, the computer sending a message repeats each bit three times, so a 0 is sent as 000 and a 1 as 111. The receiving computer "decodes" each triplet by majority rule: whichever number, 0 or 1, appears more often in a triplet is declared to be the intended bit. For example, both 000 and 100 are decoded as 0, while 101 and 011 are decoded as 1. Suppose that 6% of bits are switched (0 to 1, or 1 to 0) during transmission between two particular computers, and that these errors occur independently during transmission.(a) Find the probability that a triplet is decoded incorrectly by the receiving computer.(b) Using your answer to part (a), explain how using triplets reduces communication errors.(c) How does your answer to part (a) change if each bit is repeated five times (instead of three)?(d) Imagine a 25 kilobit message (i.e., one requiring 25,000 bits to send).
