Answer:
A is the answer
Explanation:
………… is the Energy stored in chemical bonds.
Answer:Energy, potential energy, is stored in the covalent bonds holding atoms together in the form of molecules. This is often called chemical energy. ..
Explanation:This movement is a form of kinetic energy, and the more the molecules move the more kinetic energy they have. Molecules in solids don't move much, they just vibrate
Answer:
ANS is potential energy

Sand and gravel in a mixture have the same properties as sand and gravel when they are not mixed.
Since gravel is bigger than sand,
A.
the sand and gravel can never be separated.
B.
the sand and gravel can be separated with a sieve.
C.
the mixed sand and gravel will stick together.
D.
the mixed sand and gravel have a lower volume.
Answer:
b
Explanation:
There are two types of mixture, one is homogeneous mixture and other is heterogeneous mixture. Therefore, the correct option is option B that is the sand and gravel can be separated with a sieve.
What is mixture?When two or more compounds are combined but each ingredient retains its chemical identity, the result is referred to as a mixture. In other words, there is no chemical interaction between the parts of a combination. According to how consistent they are and how well the components' particle sizes match up, mixtures are categorized.
Sand and gravel in a mixture have the same properties as sand and gravel when they are not mixed. Since gravel is bigger than sand, the sand and gravel can be separated with a sieve.
Therefore, the correct option is option B.

In which situation would osmosis most likely occur in cells?
Across a semi-permeable membrane that separates solutions of the same concentration
Across a semi-permeable membrane that separates solutions of the same concentration
Across a semi-permeable membrane that separates solutions of different concentrations
Across a semi-permeable membrane that separates solutions of different concentrations
Across a non-permeable membrane that separates solutions of the same concentration
Across a non-permeable membrane that separates solutions of the same concentration
across a non-permeable membrane that separates solutions of different concentrations
Across a non-permeable membrane that separates solutions of different concentrations
Answer:
it would most likely occur
———————————————————————————————————————
Across a semi-permeable membrane that separates solutions of different concentrations
———————————————————————————————————————
this is because osmosis is the ‘net’ movement of molecules from a ‘region’ of ‘higher concentration’ to a ‘region’ of ‘lower concentration’ ‘down the concentration gradient’.

Explanation:
Calculate the mass of an object that has a density of 20 g/mL and a volume of 5 mL.
Answer:
4
Explanation:
density= mass/volume
Answer:
100kg
Explanation:
[tex]density= mass/volume[/tex]
using this formula you can re arrange the equation my moving the volume onto the opposite side
giving you this formula : mass= density x volume
in doing so you can calculate the mass of the object by extracting the relevant information of the question
density=20g/ml
volume=5ml
mass = density x volume
=20 x 5
= 100

Explanation:
A tall pea plant (Tt) is crossbred with another tall pea plant (Tt). The following Punnett square shows the separated alleles for two pea plants.
Which of the following shows the correct match of the box numbers and the genotype of the offspring?
Btw graph is below (ScreenShot)
Answer:
B.
Explanation:
when you use punnett squares, you cross the different genes with themselves. if T is in the first box on both sides, the genome will be TT. if the box lines up to tt, it will be tt. the boxes on the left use the genes' first letter and the boxes on the right use the second letter.
The result of the cross between Tt and Tt would be TT, Tt, Tt, tt.
Monohybrid crossingThis is a kind of crossing involving only one trait.
The genotype Tt will segregate to T and t respectively.
Crossing Tt and Tt:
Tt x Tt
TT Tt Tt tt
Thus, box 1 will contain TT, box 2 will contain Tt, box 3 will contain Tt, and box 4 will contain tt.
