Explanation:
Hershey and chase experiment proving that DNA is the genetic material. When the bacterial cells were infected with the P 32 and on entry on DNA it showed the entry of DNA in the cells.
What is the full form of DNA ?The full form of DNA is deoxyribonucleic acid where it is the deoxyribose sugar combined with nucleotides with the phosphorous group.
Bacteriophages are the species which only pass on their genetic material inside and in the experiment it followed the same protocols as well where the radiolabelled DNA with P 32 showed entry in the bacterial cells.
Therefore, bacteriophages are the showing radioactivity when the phosphorous combined with P 32 got mixed and expressed inside the DNA .

Some cells can die as a result of external agents suck as poison or trauma. However, most cells die through a process known as apoptosis, or programmed cell death. What is a likely consequence of a mutation that prevents apoptosis
Answer: A tumor
Explanation:
A mutation that prevents apoptosis can disrupt the normal cellular mechanisms that prevent tumor formation, and lead to the uncontrolled growth of cells that could ultimately cause cancer.
What is apoptosis?A mutation that prevents apoptosis, or programmed cell death, can have several consequences. One of the most significant consequences is the accumulation of damaged or abnormal cells, which can lead to the development of tumors and cancer. Apoptosis is a natural process that eliminates cells that are no longer needed or that are damaged beyond repair. This process is essential for maintaining tissue homeostasis and preventing the growth of abnormal cells.
When cells are prevented from undergoing apoptosis, they may continue to divide and proliferate uncontrollably, leading to the formation of a mass of cells known as a tumor. This is because cells that have undergone DNA damage or that have other abnormalities are normally eliminated through apoptosis to prevent the accumulation of cells that could become cancerous.

1) You are studying the uptake of a certain molecule into cells that produce no ATP. You discovered
that it in fact does become transported into the cell. To further your research, your colleague
decides to do the same experiment but supplies the cell with ATP. He discovers that the cell
transports more of the molecule intracellularly.
a. Describe the difference in transport between your experiment and his. Explain. (10pts)
b. What characteristics must this molecule have in order to use both types of transport?
(10pts)
Answer:
Your cell use passive transport whereas your colleague cell use active transport.
Explanation:
There is a great difference in the type of transport between your experiment and his because you provide no ATP to the cell for transport means you use passive transport in which the cell moves molecules without the use of energy while on the other hand, your colleague provides ATP to the cell means the cell transports molecules with the use of energy so the cell use active transport. The characteristics of molecules have the presence of both type of cells which do both type of transport.

Come up with five ethical guidelines for research. Write statements that reflect your own views of
what is right and wrong. If you really love animals, an example of one guideline might be "No
animals may be used in research of any kind." However, when coming up with these guidelines, be
thoughtful about what they really mean. Think of the information you read about earlier. Try to
phrase your guidelines in a way that would allow research that you think would be beneficial to
still be done. You may find that certain circumstances may cause you to rethink your own ethics!

Bird guides once listed the myrtle warbler and Audubon's warbler as distinct species because of differences in color patterns of the feathers and size of the beak. Recently these birds have been reclassified as eastern and western forms of a single species, the yellow-rumped warbler, based on the observation that the two forms interbreed often in nature and the offspring have good survival and reproduction. The earlier classification into two species was using a species concept; the reclassification is using the species concept. _________
Answer:
morphological; biological
Explanation:
The morphological species concept highlights the importance of physical traits to delimit species. This concept is useful for classifying asexually-reproducing organisms and where lack information on interbreeding (for example, to classify fossils). On the other hand, the biological species concept states that one species represent a group of organisms that can interbreed (or potentially can interbreed) in order to produce fertile offspring. The biological species concept is nowadays the most widely accepted concept to define species.

What are resources a living thing needs to survive? Are these resources limited or unlimited?
Answer:
The basic resources a living organism needs to survive are sustinence, shelter, and heat. Sustinence is not an unlimited source and wild animals have to hunt to get their food, and if they hunt too much, the food chain will fall out of balnce to where there is no more of that species.
Shelter or safe homes can also be limited, from animals that find natural spots, or make their own homes out of resources, it can be difficult to not be constantly exposed to the natural environment.
Heat is dependant on climate, and is provided by the sun. Nonetheless, in the winter, it isn't reliable, and in the summer, animals may overheat. In conclusion overall, all of these resources are limited or depending on such circumstances.
