The atoms in any compound are held together by some bonds. These bonds are chemical bonds.
A chemical bond is an attractive force which hold the various components of a compound together. It provides stability to the compound by loss of energy. The more strong a chemical bond, the stronger is the chemical compound.
A compound is the bonding of two or more atoms tied together. It can be a molecule or a group bound together. To or more different atoms which are together but not covalently bound is a mixture.
Types of chemical bonds found commonly are:
1. Ionic bonds
2. Hydrogen bonds
3. Covalent bonds
4. Polar bonds
Hence, the atoms in a compound are held together by chemical bonds.

The question lacks options, the options are:
A) They are easier to transport and store than injectable vaccines (shots).
B) They make it easier to administer edible vaccines.
C) They are more expensive than potatoes without the vaccine.
D) They have nutritional value while potatoes without the vaccine do not.
Thw answer is C
Explanation:
Agricultural crops have faced series of problems caused by pest, nutrient composition etc. However, technology has made sure they these problems are reduced in the least possible way via the use of genetic engineering. Genetic engineering, also called genetic modification is the manipulation of an organism's genes using biotechnology procedures.
In this case, the potato crop was genetically modified, meaning that, the crop was improved genetically. Although, this process has many advantages like inserting a vaccine in the edible crop and easy storage, it also has disadvantages. One of these disadvantages as mentioned in the options is that they become more expensive than potatoes without the vaccine. The price increases due to the vaccines they now contain in comparison to the potatoes without vaccine (not genetically modified).
This price can become not affordable for an average person. Hence, it is a disadvantage of the genetically modified potato crop
b. Genetics
c. Glandular disorder theory
d. Set point theory
Answer: c. Glandular disorder theory
Hypothyroidism is an endocrine system disorder in, which the thyroid gland does not produce adequate amount of thyroid hormone, which is required by the body to function properly. Glandular disorder theory suggests the fact that hypothyroidism is responsible for the increase in weight and obesity. Treatment of thyroid hormone, does not cause a significant reduction in weight.
The items in order from smallest to largest are: virus, bacteria, red blood cells, and nerve cell.
In order from smallest to largest, the items you listed can be arranged as follows: virus, bacteria, red blood cells, and nerve cell. A virus is the smallest out of these options, typically ranging around 20 - 400 nanometers. Bacteria are slightly larger, generally falling within the 1 - 10 micrometers range in size. Red blood cells are typically about 6-8 micrometers in diameter, which is larger than most bacteria. Finally, the nerve cell, also known as a neuron, is the largest of the group. The body of a neuron can range from 4 - 100 micrometers in diameter, and their axons, or long projections, can be up to one meter long.
