The answer is D, <span>Each daughter molecule contains one DNA strand from the parent molecule.</span>
Answer:
The correct model is D.
Note: The first attachment below shows the different models. The second attachment shows the correct structural model of the water molecule.
Explanation:
A water molecule is composed of one atom of oxygen and two atoms of hydrogen.
A water molecule is polar, i.e. it contains positively and negatively opposite ends. The polar nature of the water molecule is due to strong electronegativity of oxygen which results in an uneven sharing of the bonding electrons between oxygen and hydrogen. The oxygen atom attracts the shared electrons more to itself, thereby, it acquires a partial negative charge, while the hydrogen atoms acquire a partial positive charge.
The bond angle between the oxygen and hydrogen atoms is approximately 105°. Therefore, from the first attachment below, the correct model for the water molecule is D.
Answer:
"without light energy from the sun, photosynthesis would still occur" is completely false. Light energy is needed for the light-dependent reactions, or simply the light reactions, of photosynthesis.
"oxygen is an input into photosynthesis, carbon dioxide is an output" is also completely false. It is the opposite.
These statements are true, however:
SUNLIGHT
CARBON DIOXIDE
WATER
MINERALS
OXYGEN
PLANT SUGARS
Carbon dioxide enters the leaves through stomata (tiny holes) in the leaves.
Sunlight is an input, CO2 is an input, water is an input (taken in through the roots, transported through the veins), minerals are a collective input, oxygen is an output (produced during photolysis), and plant sugars are an output (glucose, for an example).
First you must know that a diploid cell has double the amount of chromosomes of a haploid cell. A diploid cell has 46 chromosomes. When we divide 46 by 2 you get 23. This means that there are 23 chromosomes in a haploid cell.
Hope this helped!

Answer:
3.14g (3.s.f.)
Explanation:
change in mass = 0.25
mass at start = 7.96
percentage change in mass = 0.25/7.96 × 100
= 3.14g (3.s.f.)
