Hi,
The answer is very simple and of basic nature, let us get into the basics.
We have studied since very long that atoms form chemical bonds with other atoms because they want to get stable. They can get stable through octet or duplet rule that means that atoms needs to have two (in the shell nearest to nucleus) and eight electrons in the outer most shell.
So, if an atom already has enough number of electrons that it is obeying octet or duplet rule, it means that the atom is stable. It will tend not to form a chemical bond with other atom by sharing, losing or gaining electrons. Now, the electrons in outer most shell are called valence electrons and they are distributed in sub-energy levels, s and p respectively. S orbital can accommodate only two electrons, while P can accommodate 6 electrons, d can accommodate 10 electrons while f orbital can accommodate 14 electrons. So, we can say that the bond formation is the most important property of an atom and it is strongly effected by number of electrons in an energy level.
In addition, number of electrons in outer most shell also effect many other properties of an atom like shielding or screening effect, metallic or non-metallic nature that also effects the chemical bonding of atoms. Since, metallic nature of an atom is due to its ability to lose outermost shell's electrons. Therefore, the whole phenomenon of chemical bonding is linked with number of electrons in outer most shell.
Hope it helps!
Answer:
Nutrients from breast milk.
Explanation:
Healthy newborns make blood glucose from sugar and several nutrients from the colostrum, a type of liquid that mother’s breasts produce before breast milk itself. Later, the babies make glucose from mature breast milk.
Most healthy babies, born after 37 weeks of gestation do not risk hepatic glycogen drops. They can easily compensate for normal drops in blood sugar, in other words, whenever the baby is breastfed when needed, he/she will be able to keep his/her glucose levels stable.
The cell wall is the outside layer of the cell whereas the cell membrane is surrounds the cytoplasm of the cell.
Answer:
To determine the effect of toxin binding, you perform a Competitive Binding Experiment
Explanation:
Competitive binding experiments are very relevant when matters relating to cellular and or molecular toxicity are concerned.
They are used to determine the binding of a single concentration of labeled ligand in the presence of various concentrations of unlabeled ligand.
They are important because:
1. Validate a direct binding assay
2. Confirm whether or not a drug binds to the receptor
3. determine and explore how low-affinity drugs and receptors interact and it's resultant effects

It is B, because that is how they produce their scientific name
