Answer;
-Triglyceride or Fats
Explanation;
-Fat consists of two parts: glycerol backbone and three fatty acids tails. fatty acid consists of long hydrocarbon chain and a carboxyl group. glycerol is organic molecule with three hydroxyl groups.
-Triglycerides are fats from the food we eat that are carried in the blood. Most of the fats we eat, including butter, margarines and oils, are in triglyceride form. They are the most common type of fat in the body. Triglycerides are necessary for health but in excess amounts, they may be harmful and may increase the risk of heart disease.
Answer:
Flow rate is the speed at which the volume of water moves through an aquatic ecosystem. It refers to the amount of water that can move from one region of the aquatic system to other in a given period of time. The flow of water affects the temperature, salinity of water and the living organisms surviving in an aquatic ecosystem.
a. Amphibians and birds share a more recent common evolutionary ancestor than sharks and birds.
b. Birds and sharks do not share a common evolutionary ancestor.
c. Having a bony skeleton did not provide an evolutionary advantage to sharks or ray-finned fish.
d. Rabbits and primates diverged more recently than crocodiles and birds.
Answer: a. Amphibians and birds share a more recent common evolutionary ancestor than sharks and birds.
Explanation:
A cladogram is a diagrammatic representation of the phylogenetic relationship of recently evolved species with their common ancestors. The relationship is defined on the basis of genetic, molecular, morphological make up of the organisms. The node in the cladogram defines a divergence or difference between the two taxon.
Birds and amphibians share a more recent common ancestor than shark and birds because they can be seen lying closer at the terminal ends of the cladogram.
Answer;
-Mitochondria
Explanation;
-Viruses are small infectious agents that replicates only inside the living cells of other organisms. Some of the features of viruses includes;
-They are enclosed in a protective envelope.
-They have spikes, which helps them to attach to the host cell.
-They are non cellular.
-They do not respire, do not metabolize and do not grow but they do reproduce.
-They contain a protein coat called the capsid.
-They have a nucleic acid core containing DNA or RNA.
