Answer:
The requirement of different nutrients, divide them into 2 categories.
Explanation:
On the basis of requirement of nutrients in our food, the chemicals are divided into 2 types - macronutrients, and macronutrients.
Nutrients are the molecules present in the food nourishes the living organisms. The macronutrients are needed in large quantities and they provide energy to the organism.
There are 3 major macronutrients present in every kind of food - proteins, fats, and carbohydrates.
On the other hand, micronutrients are required very less amount to the animals. But they are important for nourishment of the body, but their quantity is very less. Example of micronutrients are vitamins, minerals, manganese, iron, potassium, etc.
Therefore, it is told one should take balance diet to get all the nutrients.
Hair cells are sensory receptors so definitely it needs food to survive which is gotten from hair cream that has vitamins and nutrients.
The endomembrane system<span> is a group of cell membranes and organelles that are mutually interconnected, either by being directly continuous with one another or by sending one another </span>vesicles<span>—little spheres of membrane then can bud off from one membrane and fuse with another.
</span>The rough endoplasmic reticulum<span> (</span>rough ER<span>) gets its name from the bumpy ribosomes attached to its cytoplasmic surface. As the ribosomes attached to the rough ER make proteins, they feed the newly forming protein chains into the lumen.
</span>
The smooth endoplasmic reticulum<span> (</span>smooth ER) does not have ribosomes on its cytoplasmic face.<span>The smooth ER has a variety of functions, and its exact role may vary between cell types.
</span>
<span>One role of the smooth ER is to produce lipids, including phospholipids, cholesterol, and steroids.

Answer:
Hydrogen bonds tend to be weaker than covalent or ionic bonds. The hydrogen bond formed between water molecules has a dissociation energy of 0.24 eV. A hydrogen bond has is approximately 90% ionic and 10% covalent. Van der Waals bonds are weak bonds with a dissociation energy of about 0.01 eV.
Explanation:
The correct answer is d. Robertsonian translocation.
The translocation can be defined as the chromosomal rearrangement, which takes place between two non homologus chromosomes. In the Robertsonian translocation a fragment of the chromosome is replaced with the fragment of another chromosome. In this way, the Robertsonian translocation result in structural abnormality in two chromosomes.
