Answer:
<h2>
A. mRNA ( messenger RNA),B. rRNA (ribosomal RNA) and C. tRNA (transfer RNA )</h2>
Explanation:
A. mRNA ( messenger RNA);
i)it is the most abundant form of RNA
,
ii) specifies the amino acid sequence for a protein
,
iii) contains exons.
B. rRNA (ribosomal RNA);
i) it is assembled in the nucleolus
,
ii) is a component of ribosomes
.
C. tRNA (transfer RNA );
i) contains anticodon,
ii) has amino acids covalently attached
.
Answer:
300% - 400%
Explanation:
The cardiac reserve is in the range of 300 to 400 percent (300% - 400%
) in normal young adults, while this percentage can be increased to 600% in trained athletes
the offspring has a 50% chance of having black feathers and a 50% chance of white feathers
An experiment to test the best conditions for bacteria to grow is the material that the bacteria feed upon. <u>Option D.</u>
<u />
Antibacterial hand soap with different concentrations. Dependent variable bacterial growth as measured by the diameter of the zone of inhibition. Exposing Petri dishes to different temperatures can skew the level of bacterial growth they inhabit. Plant height is the dependent variable that responds to changes in the independent variable.
Sunlight is the controlling variable because each plant is exposed to the same amount of sunlight. It is the dependent variable because it measures the amount of plant growth. The dependent variable depends on the independent variable. How much plants grow depends on how much sun they receive. A continuous increase in temperature from a minimum value increases the rate of bacterial growth because the rate of metabolic reactions increases with increasing temperature.
