The evaluation of their DNA and short tandem repeats will let them know if the birds are related or not. The genetic linkage will provide information about their common ancestry as well as if they belong to the same species, or are closely related species.
Answer:
Option A) Double-stranded DNA
Explanation:
Note that the presence of thymine, a pyrimidine nitrogenous base in the genome indicates the presence of DNA.
Then, the summation of 28% adenine + 20% thymine + 35% cytosine + 17% guanine to yield 100% confirms that the DNA is double-stranded.
Thus, the structure of the viral genome is Double-stranded DNA.
The autotrophs are the primary producer in the food chain and they are the ones who initiate the food chain. They produce food by using sunlight or sometimes chemical energy or reactions. They primarily use carbon dioxide, sunlight and water to form sugars or carbohydrates which become their energy source. They use the process of photosynthesis or chemosynthesis to generate food. Examples of autotrophs are green plants, green algae, bacteria.
Heterotrophs cannot make their food via sunlight or other inorganic sources and hence are dependent on the autotrophs or other animals. The heterotrophs have been ranked as secondary and tertiary consumers and cannot be producers. They consume the organic products made by autotrophs to obtain energy for various metabolic and biological activities. The heterotrophs can be herbivore, carnivore, fungi, parasitic plants.
Some are photo-hetrotrophs, who use light as energy but cannot use carbon dioxide as the carbon source since they cannot fix the carbon like autotrophs.
These defenses are described as nonspecific because they do not target any specific pathogen; rather, they defend against a wide range of potential pathogens.
<h3>Is innate immunity nonspecific resistance?</h3>
The innate immune system provides this kind of nonspecific protection through a number of defense mechanisms, which include physical barriers such as the skin, chemical barriers such as antimicrobial proteins that harm or destroy invaders, and cells that attack foreign cells and body cells harbouring infectious agents.
Thus, they do not target any specific pathogen; rather, they defend against a wide range of potential pathogens.
