Chromosome is a threadlike structure present in nucleus .Chromosomes are composed of chromatin and carry the genes in a linear sequence; these determine the individual characteristics of an organism there are 23 pairs of chromosomes out of those one is different. In female it is XXY qnd in males it is xy

Answer:
Glucose 
Oxygen gas
Explanation:
Glucose is a non-metallic carbohydrate substance. It is the monomeric unit of the digestion of complex carbohydrate. 
This compound is very important to all lives. The energy needed to power the activities in the body are derived from the compound. 
It is made up of carbon, hydrogen and oxygen atoms. 
Also, oxygen gas is used by animals for their metabolic processes. The gas combines with glucose to release chemical energy for use in the body. This molecule is purely made up of two atoms of oxygen that are covalently bonded together. 
Anytime we breathe, we take in oxygen for use in our body
 
        
             
        
        
        
Indigenous Information System (IKS) is the body of knowledge that communities have accumulated over many generations as a result of their interactions with the environment.
<h3>Indigenous Knowledge System (IKS): What is it?</h3>
The technological, economic, philosophical, educational, and governing systems are all included in the indigenous knowledge system.
Prior to the development of the contemporary scientific knowledge system, indigenous societies established their own knowledge, which is included in indigenous knowledge systems (IKS).
Acupuncture from China is an illustration of IKS. Through the preservation and wise use of biodiversity, it may significantly advance sustainable development.
There is a definite need to preserve these systems, acknowledge their worth, and stop their destruction in order to strengthen indigenous knowledge practices and cultures.

Answer: by given steroid injection to animals 
                                   <u>and </u>
                    increasing production of cheap calories of Sugar and Triglycerides  for use in food products
The attempt by farmers to maximize profit prompted them to give hormones e.g streroids to  animals to increase their  biochemical reactions therefore the the products yields e.g they  are  giving  steroids  to poultry  to  improve chicken, eggs production;and  to  cattle for improved beef and milk production.
In order to obtain maximum sugar and fats productions, cheap calories  forms of there  are being  produced. e,g fructose, maltose. if  maltose  is consumed in excess  it leads to  obesity, while fructose increases the level of cholesterol.These products  requires a lot of processing with different chemical products which leads to health problems after consumption
