A stock of different genes in a interbreeding population
Answer:
Little increase in cell number
Explanation:
There are four distinct phases in the bacterial growth curves that is lag, log, stationary and death phase. The lag phase of the bacterial growth curve is characterized by very little increase in the cell number.
The growth rate of bacteria in the lag phase is slow because the medium is new to the bacterial culture and it requires time for bacteria have to adapt to the new cultural environment and to synthesize enzymes required for substrate utilization.
After getting adapt in their new environment bacteria starts to grow at an exponential rate. So little increase in cell number characterizes the lag phase.
Answer: The following statements <em>comparing respiration in fish and in mammals</em> is correct:
- The movement of the respiratory medium in mammals is bidirectional, but in fish it is unidirectional.
Explanation:
<u>Breathing </u>is the process by which living beings <em>exchange gases</em> with the external environment. It consists of the <u>entry of oxygen</u> into the body of a living being and the <u>exit of carbon dioxide</u> from it .
Active ventilation occurs if the animal produces the currents (of air or water) that flow to and from its respiratory membranes. It can be :
- Unidirectional. (air or water is pumped onto the respiratory membrane in only one direction).
- Bidirectional. (air or water is transported to the respiratory membrane and moves away from it through the same route like in the mammals).
Answer:During transcription, the sequence of DNA is transcribed into mRNA. Later, during translation, mRNA sequence is translated into a protein molecule
Explanation:
i did it
Explanation:
Such an offspring would have the genotype YY, which are the dominant alleles that code for yellow colour in bananas.
In the Punnett's Square, none of the offspring have YY genotype. Hence the answer is 0%.
