Answer:
a microscopic single celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles. Prokaryotes include the bacteria and cyanobacteria.
Answer:
The correct answer is "Fist sequence; Fourth sequence; Second sequence; Third sequence".
Explanation:
Inversion of DNA is a process that often occurs during evolution of chromosomes. It occurs when the breakage of a chromosome in two places, results in the reinsertion of a DNA but in a reversed fashion. The evolutionary order of predecessors of inversion of DNA can be established by looking on the number of nucleotides that are different in the sequences of DNA. In this case, the first sequence is the ancestor and it haves the sequence "ABCDEF". The second in the evolutionary order is the fourth sequence since it originates from the first sequence only by changing the "BC" nucleotides to the end of the sequence "ADEFBC". The third in the evolutionary order is the second sequence since it still starts in AB, but has the other four nucleotides different: "ABFEDC". The last in the evolutionary order is the third sequence, which is completely different and reversed respect to the first sequence: "FEDABC".
Answer:
The frog is a secondary consumer
Explanation:
its not a primary producer because it doesnt start the chain
its not a primary consumer because the frog can still be eaten
and it cannot be a decomposer because it is not a fungi or other kind of carcass eating creature
They include the temperature and the pH value.
Each enzyme has a temperature range and pH range that makes them has the quickest action, they're called the optimum temperature and pH. Each optimum temperature and pH is different for each enzymes.
For example, the enzyme in our stomach has a optimum temperature of human temperature range, and a optimum pH for 2.0
However, if the temperature is too low or the pH value is too extreme, the enzyme may denature. The enzyme can no longer work to digests any substrate.
