Cells in an organism can develop in different ways to perform different tasks.
Answer:
The correct answers are option b. "replication bubbles" and d. "replication forks".
Explanation:
The nucleic acids replication systems share some similarities between eukaryotes and prokaryotes. For instance, both organism have replication bubbles. However, prokaryotes have a single replication bubble because its replication process starts from a single origin, while eukaryotes have several replication bubbles. Also, the replication forks are well conserved from prokaryotes to eukaryotes with only some differences among the enzymes present within the fork.
Yes, these actions are an example of homeostasis. To fully understand this question you need to know the basic concept of homeostasis. Homeostasis is the body's regulation. What do I mean by that? It's simple, when you have a fever your body's temperature can skyrocket to 100 or more, when you start to sweat or get the chills that's your body's way to cool you down and fight the infection. Another example; when you do any physical activity, you sweat from it depending on the intensity. If you didn't sweat you would probably overheat and that would lead to other complications. Basically when you do exercise you sweat because your body is warm and that's the homeostasis mechanism that helps cool down your body bring it to it's normal temperature. So in end answering your question in more detail by the liver regulating the body by taking glucose in when levels are too high or adding glucose in when levels are too low is an example of homeostasis because the body is regulating itself to come back to it's normal healthy function state.
Hope this helped :)
Answer
Cell physiology is the biological study of the activities that take place in a cell to keep it alive. The term physiology refers to normal functions in a living organism. Animal cells, plant cells and microorganism cells show similarities in their functions even though they vary in structure.

The question is incomplete as it does not have the options which are:
The empty vector would migrate the same distance as the cloned vector.
It is impossible to know without knowing the identity of the gene of interest.
The empty vector would migrate farther down than the cloned vector.
The cloned vector would migrate farther down than the cloned vector.
Answer:
The empty vector would migrate farther down than the cloned vector.
Explanation:
In recombinant technology, an empty vector is considered a vector which is present without the gene of interest and thus is of small size and the cloned vector is the vector which has a gene of interest along with the usual sequence.
The cloned vector is larger compared to the empty vector as the cloned vector has a gene of interest whereas the empty vector does not have.
In-gel electrophoresis technique, the DNA samples are run and the size of the fragment is known according to the ladder sequence which is used as a reference and have the band size in increasing order from lower side to upper side.
When the vectors sun on the gel, the small size gene will move faster and to the farthest distance compared to the larger DNA that is empty vector will cover the maximum distance while the cloned vector will cover the less distance.
Thus, the selected option is correct.
