Explanation:
Transfer ribonucleic acid (tRNA) is a type of RNA molecule that helps decode a messenger RNA (mRNA) sequence into a protein. tRNAs function at specific sites in the ribosome during translation, which is a process that synthesizes a protein from an mRNA molecule.
 
        
             
        
        
        
The branch of biology dealing with interactions along organisms and between organisms and their environment is called Ecology, I believe.
        
             
        
        
        
ANSWER: None of the above options are correct.
Cardiac Output(CO) = Stroke Volume(SV) × Heart Rate(HR)
Therefore where HR= 90bpm and SV= 110ml/min,
 
CO = 90 × 110 = 9900ml/min or 9.9L/min.
EXPLANATION:
 
CARDIAC OUTPUT is the volume of blood being pumped by the heart into the systemic circulation per minute.
Cardiac output is the product of two variables, stroke volume and heart rate. 
STROKE VOLUME is the amount of blood pumped out by the left ventricle in each contraction.
HEART RATE is the count of the number of times the heart beats per minute.

The correct answer is - B. The number and type of plants in an ecosystem determines the number and type of consumers that can live there.
The plants are producers. They are the basis of the ecosystems on Earth. By consuming the plants, the consumers are able to survive and thrive, thus the food chain develops further up to the predators that are consuming other consumers.
The number of plants and the type of plants determines what type and how many species of consumers can live somewhere. The more plants there are, the more food for the consumers, thus there will be more consumers. The higher the diversification of the plants, the higher the diversification of the consumers will be too, as every plant is unique and specialization for consuming it is needed, thus the consumers will evolve into new species in accordance to the food source.
