Answer:
a and b
Explanation:
The growth of adipose tissue in newborns is directly linked to the fact that they do not have proper body temperature control, so fat acts as a thermal insulator in order to maintain a constant temperature, also, breast milk density can also influence baby fat gain.
For the first six months the baby still has a lot of fluid retention and so it may give the impression that he is getting fatter, but after the first six months until the end of the first year, the baby tends to lose this fluid, decreasing on average 10% of body weight.
<u>Girls</u> in adolescence and pre-adolescence have a tendency to gain weight due to the enormous hormonal load they receive at puberty, as well as other factors such as poor diet.
The same does not happen as often in <u>boys</u> because a good part tends to have a "leap" growth in puberty, favoring weight loss. The process of fattening in teenage boys is more associated with sedentary practices and consumption of junk food.
Answer:
<em>The correct option is B) DNA fragments are negatively charged.</em>
Explanation:
The backbone of the DNA is made up of sugar and phosphates. The phosphates present in the backbone of the DNA are the main reason for the DNA to be negatively charged. The negative charge of the DNA allows different DNA fragments to separate by gel electrophoresis depending on their charge/mass ratio. The smaller DNA fragments will move faster towards the positive end of the gel as compared to the larger fragments and hence they will separate.

Answer:
photosynthesis, the process by which green plants and certain
other organisms transform light energy into chemical energy .
During photosynthesis in green plants, light energy is captured
and used to convert water, carbon dioxide, and minerals into
oxygen and energy-rich organic compounds.
also
During the process of photosynthesis, light penetrates the
cell and passes into the chloroplast. The light energy is
intercepted by chlorophyll molecules on the granal stacks.
Some of the light energy is converted to chemical energy.
During this process, a phosphate is added to a molecule to
cause the formation of ATP(Adenosine triphosphate)
From the information given, the lab cart has a mass of 0.5 kg and the student exerts a force of 3N on it.
We use the formula F = MV
Where F = Force, M = mass and V = velocity
In our case, F = 3N (or 3 Kg m/s²) , M= 0.5 kg , V is unknown.
F= MV → MV = F → V = F / M
V = 3 kg m/s² / 0.5 kg
V= 3 / 0.5
V = 6 m/s²
Therefore the acceleration of the cart 6 m/s²
