Answer:
Ukaryotes consist of membrane bound nucleus whereas prokaryotes lack a membranebound nucleus.
Explanation:
Ukaryotes consist of membrane bound nucleus whereas prokaryotes lack a membranebound nucleus. Prokaryotic DNA is doublestranded and circular. ... The main difference between prokaryotic and eukaryotic DNA is that prokaryotic DNA is found in the cytoplasm whereas eukaryotic DNA is packed into the nucleus of the cell.
No, DNA in prokaryotes and eukaryotes does not use the same nitrogenous base pairs.
What is DNA?Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. The polymer carries genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid are nucleic acids.
Moreover, deoxyribonucleic acid (DNA) is a molecule that contains the biological instructions that make each species unique. DNA, along with the instructions it contains, is passed from adult organisms to their offspring during reproduction.
Therefore, in all living things, DNA is essential for inheritance, coding for proteins, and providing instructions for life and its processes. DNA dictates how a human or animal develops and reproduces, and eventually dies.

4. Why does cell division take place in single celled organisms?
A In order for organisms to grow
B.te reproduce and pass along genetic information
C.to enable the organisms to heal injured tissues
D.to make specialized cells for different functions
Answer:
A) In order for organisms to grow.
Explanation:
Tell me if I am wrong. I hope this helps :)
Cell division in a cell takes place in the single-celled organisms to reproduce and pass along the genetic information of the cell. Thus, the correct option is B.
What is Cell division?Cell division is the process of division of cell through which a parent cell divides into two daughter cells with equal genetic content which are similar to the parent cell. Cell division generally occurs as a part of a larger cell cycle in which the cell grows in size and the cell replicates the chromosomal material before it is undergoing cell division.
In the unicellular organisms, cellular division is a significant process through which a unicellular organism undergoes development and result into the formation of a new organism with genetic material which is similar to the parent cell. In the multicellular organisms, process of cellular division helps in maintaining a balance between the genetic material such as the DNA and the RNA contents as well as the nuclear and cytoplasmic contents of the cell.
Therefore, the correct option is B.

A long time ago, farmers discovered that if they grow the same
crops on a field, then after a few years, the crops grow more slowly. Why does
this happen?
Answer:
Because they don't have fertilizer.
Explanation:
Well, if this was a long time ago, then farmers did not have fertilizer. So, there are bacteria on the roots of plants that convert nitrogen into a usable form. It's very important for growing, and when farmers harvest the crop, not much of the nitrogen is returned to the land, so it is not as fertile. Fertilizer is largely consisted of nitrogen, so that is why farmers use fertilizers today. But "a long time ago," farmers did not have fertilizer.

the cells produced during meiosis are?
Answer:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. During reproduction, when the sperm and egg unite to form a single cell, the number of chromosomes is restored in the offspring.

Needs answers for both thanks
Answer:
The answer to the first question is A.
The answer to the second question is False.
Explanation:
An animal's fur color is like a human's skin color. If both parents are the same color, the children will have the same. If it is a mix, it will either mix the colors or just be one. So as both mice are white colored, the offspring will be white furred too.
Now for the second question. Once again, just like humans, mice inherit traits about the same. The traits from the parents will most likely carry on. There is also times where a new trait comes in. This is not very common but it happens occasionally.

Explanation:
Air tends to flow faster over ______ formations.
a. sheltered
b. medium-sized
c. shorter
d. taller
Answer:
d. taller
Explanation:
The air tends to flow faster over taller formations. Therefore option D is correct.
When air encounters different formations or obstacles, it can affect the speed and behavior of the airflow.
Taller formations, such as tall buildings, mountains, or cliffs, can create an obstruction in the airflow. When air encounters a taller formation, it is forced to flow up and over the obstacle.
As a result, the airflow can accelerate on the windward side of the formation and create faster wind speeds. This phenomenon is known as an acceleration zone or an area of increased wind speed.
Therefore, the correct option is d. taller formations. Taller formations can cause the air to flow faster due to the presence of acceleration zones or areas where the airflow is forced to speed up as it interacts with the obstacle.
