Answer:A. the same number of chromosomes as was contained in the zygote.
Explanation:a zygote is formed when the sperm fertilize the egg .
After fertilization,the zygote undergoes cleavage.cleavage is the mitotic Division of the cells of a zygote to produce daughter cells.
These daughter cells are called blastomere,which contains the same number of chromosomes as the parent cells.the cells formed do not grow in size but continues to divide, forming a mass of cells.
This mass may be solid at first but as cleavage continues,the cells move away from the center,leaving a fluid filled cavity in the middle (blastocoel).
The mass of cells are called blastula.
The part of the question about the size of the sponge is just there to trick you; you don't need it. All you need is the 22.5 L per day.
To find the amount of water it can pump in 1 hour, you divide the 22.5 by 24 because there are 24 hours in a day:

Now that we have hours, we can divide that by 60 to get the amount pumped per minute (because there are 60 minutes in an hour):
Answer:
The correct answer is option C.
Explanation:
Human subject research is an investigation or research that include human as the subject. In other words, An Investigator conducts clinical research on humans getting data through interaction and intervention of individuals.
investigator A has investigated biological specimens. These specimens are coded and linked to the identifiers. Investigator B's research using biospecimens human subject is not according to the human subject research in the federal regulations as investigator B did not get the individual identifiers.
Thus, the correct answer is option C.
Answer:
Explanation:
First step
We can locate the problem and identifying it, there are tools to identify some computer problems or just we can use the logic.
Second step
Researching ways to solve the problem, we can find any solution on the internet, we can research in forums or technology platforms.
Third step
Trying a number of simple fixes initially, If we find different solutions, we can start to try with some of them.
Fourth step
Seeking help to solve the problem, if we could not resolve the problem, we can call technical service or any specialist.
Answer:
This question seem incomplete
Explanation:
This question seem incomplete. However, if the strand of the second fragment is what is provided above, then the answer is <em>51</em>
This strand/fragment is definitely a DNA strand because of the absence of uracil (U) or because of the presence of thymine (T). The four bases in a DNA are adenine (A), Thymine (T), cytosine (C) and Guanine (G). These bases also bind to one another in the pattern described below
A ⇆ T
G ⇆ C
Hence, the adenine (A) on one strand can only bind to thymine (T) on the complementary strand (and vice versa) while the guanine (G) on one strand can only bind to cytosine (C) on the complementary strand (and vice versa).
Hence, the letters seen is the question are representations of bases in a DNA strand/fragment. The number of letters/bases here are <em>51</em>
