Answer:
Both birds and dogs use DNA as instructions for building their bodies even though they are very different organisms because DNA of all the organism are made up of same four type of base adenine, thymine, cytosine, and guanine. These bases make genetic code that is universal in all the organisms.

Answer:
X - Flagellum, Y - Bacterial DNA, Z - Cytoplasm
Explanation:
A bacterium is a living thing that are majorly known for causing diseases but are important for human life. 
A bacterium is also consist of several organelles such as cell wall, cytoplasm, flagellum,  bacterial DNA, cytoplasm, ribosomes and others. 
The diagram shows three main organelles that are X - Flagellum, Y - Bacterial DNA, Z - Cytoplasm. Flagella functions for the locomotion of the bacteria, bacterial DNA is a genetic material of the bacteria, and cytoplasm is a gel-like matrix composed of enzymes, water, nutrients and other waste material.
Hence, the correct answer is "X - Flagellum, Y - Bacterial DNA, Z - Cytoplasm".

Answer:
Larger islands that are large and close to the mainland are shos lower rate of extinction due to the fact that the species present have more space so there will be more resources available in comparison to smaller islands where limited space and limited resources available.
Extinction is greater on islands isolated due to the unlikelihood of immigration and as it is opposite to the island close to the mainland and competition is more in isolated islands.
 
        
             
        
        
        
<u>Answer</u>:
The food containing 200 calorie have less potential energy than the food containing 300 calorie
<u>Explanation</u>:
The potential energy content of a food material is its stored energy content which is in the form of chemical bonds. This energy can be measured through the combustion of food material inside a calorimeter. A calorimeter is an instrument which is used to measure the total calorie content of the food or other biological samples by measuring its heat content. A Calorie is unit of energy which is in form of heat. 
The food material containing carbohydrates proteins and fats have energy in form of chemical bonds.  On the breaking of bond inside the body, energy is released as in the case of glucose breakdown also known as glycolysis.  
The energy released from glycolysis is used to synthesize high energy containing phosphoanhydride bonds. These ATP molecules are a further breakdown in the system to provide energy to the cell to perform various activities.
