Why can whales not breathe underwater?
Answer:
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. ... After each breath, the blowhole is sealed tightly by strong muscles that surround it, so that water cannot get into the whale or dolphin's lungs.
10. True or False. The pH scale is the measurement system to indicate the concentration of hydrogen (H+) ions in
a solution
Answer:
that is true
Explanation:
which of the following determines the identity of an element?
a. atomic number
b. mass number
c. atomic mass
d. overall change
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.

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

A student carried out an experiment to determine how different concentrations of sucrose solution will affect osmosis. The student
set up five bags of dialysis tubing with different concentrations of solutions in each one. The first one had distilled water (OM).
followed by 0.25 M.0.5 M, 0.75 M, and 1.0 M sucrose solutions. These bags were placed in distilled water for thirty minutes. The bags
were then massed removed from the distilled water and massed on a scale. Revise the experiment by selecting all of the choices
below that would strengthen the experimental design
Answer:The bags should be massed before going into the distilled water, the temperature of the solutions in the experiment should be held constant, the bags should be kept in the distilled water soil it ion for the same length of time.

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

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.
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.
