The 2 major components or parts that compose or make up the plasma membrane of a eukaryotic cell would be the phospholipids arranged as a bilayer, having phospholipids arranged side by side in an upright and inverted manner, allowing for the hydrophobic and hydrophilic regions to interact respectively, and also Protein molecules, more specifically Transmembrane Proteins and Integral Proteins.
Carbohydrates are composed of carbon, hydrogen, and oxygen
The answer is option B. The number of protons
If two atoms are isotopes of the same element then the number of protons in those two atoms must be same but the number of neutrons must not be same. If number of neutrons of an atom vary but number of protons in them are same then it simply means that they both are isotopes of a particular element. As we know that every atom has a nucleus which has protons and neutrons and due to these protons and neutrons an atom has weight. Apart from that, an atom has electrons too but they are outside the nucleus. Electrons are extremely light in weight so they do not contribute towards weight but they have a great role in chemical reactions. During chemical reactions, it is electron which directly participates, while proton and neutrons do not take part or move during chemical reactions. Also, in a neutral atom number of protons is equal to number of electrons but when an atom becomes negatively or positively charged, it can gain or loose electrons so electrons have tendency to vary. That is why we cannot consider electrons to be always same for isotopes of an element. It is clear that for an isotope, the number of electrons and neutrons will vary but the number of protons will always be fixed.
Answer:
Attachment Bond
Explanation:
Attachment Bond is defined as the bond that forms a strong relationship between a child and a primary care giver(E.g The Mother)
It is called the sensory-motor stage of a child and it takes place between the ages of 0-24months of a child.It is the age which a child experiences Object Permanence and Object Absence(Example:An infant/child at this age who is always carried by the mother will feel the absence of his mother when she is absent.By this,the child is specially bonded to his mother and tends to know when she is present/absent.It is also the age of Egocentrism.
