Answer:
<h2>a. 1000 X 2^8</h2>
Explanation:
As given;
Initial population of bacteria= 1000;
Log phase growth is exponential phase, period in which bacteria gets double.
Generation time= 15 minutes;
it means, bacteria get double in every 15 minute,
so after 2 hours, bacteria will have 8 generation times;
so the final generation of bacteria is =1000 X 2^8.
Final bacterial generation after two hours = 256,000(1000 X 2^8)
Answer:
DD or Dd
Explanation:
Dimples is the dominant trait (D). Your friend has dimples so that means he or she should have at least one allele of the dominant trait to express that trait. So your friend would either be homozygous dominant (DD) or heterozygous dominant (Dd). Notice that there is a recessive allele in the second. Even with that present, dimples would be still expressed.
That would be skeletal muscle, which is also a voluntary muscle.
1. The cell wall has lignin (hard substance): to prevent the xylem vessel from collapsing and withstand high pressure.
2. The absence of protoplasm (nucleus + cytoplasm) and cross wall: to allow water to move through the lumen easily.
