Answer:
The innate or nonspecific immune system includes two lines of defense in the human body. Non-specific means that it does not act on the specific pathogen. It works equally to keep all types of pathogens such as bacteria, viruses, parasites et cetera out of the body.
The first line of defense includes physical barrier which prevents the entry of pathogens into the body. It includes skin, respiratory tract, gastrointestinal tract, cilia, nasopharynx, eyelashes, and body hairs.
It also includes chemical barriers such as mucus, gastric acid, bile, tears, sweat, and saliva.
The second line of defense includes anti-inflammatory responses, fever, and nonspecific cellular responses such as phagocytes, macrophages, complement system et cetera.
Thus, the virus has to pass physical, chemical, and nonspecific cellular responses of the body in order to infect the body.
Answer:
(A) Sex-linked dominant
(B) Sex-linked recessive
Explanation:
This type of representation is used in pedigrees that express the inheritance of sex-linked characters, that is, those that are inherited through one of the sex chromosomes, which are the X or Y chromosomes.
For this reason it is necessary to represent males and females differently in the scheme

Answer:
Spring can be considered as backbone of the DNA.(as picture is missing there)
Explanation:
In DNA double helical model two main structure are there-
1- Backbone consist of phosphate group and the pentose sugar. It is like two vertical columns of a ladder. In helical structure two complementary stands are there one is 3' to 5' and another one is 5' to 3'.
2- Nitrogenous bases are like horizontal bars of ladder attaching two vertical strands. There are 4 kinds of nitrogenous base ADENINE , THYMINE , GUANINE , and CYTOSINE. One more nitrogenous base URACIL is also there but found in RNA not in DNA.
DNA is made of nucleotide and a nucleotide molecule is made of pentose sugar(deoxyribose) ,phosphate group and nitrogenous base.
I believe the answer is Sugar-sweetened beverages
Empty calorie is term used for food with high amount of calorie but have little to none nutrient. This food will give energy but not giving the nutrient that the body need to be healthy. Typical food would be the one with high sugar or fat content. Consumption of empty calorie food will provide more calorie, make the person easier to gain weight.
