Answer:
Courtney is looking at Prokaryotic Cell.
Explanation:
Ok, when Courtney is observing the science experiment, and finds a cell that includes DNA and has a nucleoid region but does not have nucleus, it is a prokaryotic cell and only the single-celled organisms of the domains Bacteria and Archaea are classified as prokaryotes, where pro means before and kary means nucleus.
Let's explain what is a prokaryotic cell: prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid. And most prokaryotes have a cell wall outside the plasma membrane.
DNA structure, function and replication. DNA is a long molecule that consists of two strands of nucleotides twisted together in a long spiral called a double helix, the base-pairing rules describe which bases pair together in a DNA double helix, work together to produce two identical copies of the original DNA molecule=DNA structure; DNA funcution; RNA; replication; transcription; translation; the two strands are wound round each other to form a double helix. The two strands. Are joined together by hydrogen bonds between the bases, before every cell divison, so that one identical copy can go to each daughter cell =because the two strands of a DNA molcule have complementary base pairs, the nucleotide each can be used as a pattern or template to produce a complementary strand together then form a new DNA double helix, identical to the orginal. The enzyme DNA polymerase then moves along the exposed DNA strand
The answer Peter will consume 60 sixpacks of Miller lite per
year.
The solution for this problem is:
The cost of 6 Miller six packs is 5 * 6 = 30.
Then the cost of 2 Bud cases is 30 * 2 = 60.
Consequently, Miller is low-priced so Peter will buy as much Miller as
possible. Therefore, <span><span>300 which is the budget divided by 5 is the cost for the Miller sixpacks = 60</span></span>
Answer:
<em>The correct option is C) The success of a species depends on the number of offspring that survive long enough to reproduce.</em>
Explanation:
Some species of animals such as the octopus might give rise to many offspring, but these offspring might not survive due to different reasons. Only a few of them will be able to survive until the age where they can reproduce.
On the other hand, the survival rate of offspring which are formed in lesser numbers is more. These offspring are taken care of by their parents usually or are better adapted to live in the environment. Hence, their survival rate is more.
Explanation:
The influence from radioactivity is inversely proportional to the number of chromosomes , since , humans have more DNA , chromosomes than the insects , and therefore , due to less chromosomes in insects , they are more resistant towards radioactivity .
As the target of the radiation is the DNA .
Hence , It is clear that insect due to lesser DNA are less prone to Radiations .
