Answer:
0.325 microliters
Explanation:
1 microgram = 1000 nanograms
DNA sample concentration= 1000 X 0.6 = 600 nanograms / microliters
We need a total of 50 microliter reactions, and the concentration should be 3.9 nanograms per microliter.
So, we need total 50 X 3.9 = 195 nanograms in 50 microliters.
Therefore, it required 195 / 600 = 0.325 microliters of DNA sample to be transferred.

What are one benefit and one consequence of building a desalination plant? Would a desalination plant be beneficial to your local area? Explain why or why not.
Answer:
Desalination plants, also known as desalination plants, are industrial facilities for desalination, generally of the sea or salty lakes, to obtain drinking water.
Explanation:
The benefits are clear: having clean water in places where it is scarce. But, on the disadvantages side, it is a process that requires a lot of energy and is therefore expensive. In addition, desalination plants have an impact on marine ecosystems that must be assessed, they increase the temperature of sea water and reduce the amount of oxygen in the water, causing serious damage to aquatic life.

The process of cell division inveukaryotes is called?
Answer:
In eukaryotes, there are two distinct types of cell division: a vegetative division, whereby each daughter cell is genetically identical to the parent cell (mitosis), and a reproductive cell division, whereby the number of chromosomes in the daughter cells is reduced by half to produce haploid gametes (meiosis).
When two pink flowers (RW) are crossed, there are four equally likely possible outcomes for the genetic makeup of the offspring: red (RR), pink(RW), pink(WR), and white (WW). If two pink snapdragons are crossed, what is the probability that the offspring will be (a) pink, (b) red, and (c) white?
Answer:
a) 50% chance of being pink
b) 25% chance of being red
c) 25% change of being white
Explanation:
Since neither the R allele or W allele is dominant over the other, this is codominance. If 2 pink ones are crossed, that means both of them are RW
If we draw out the punnet square
R W
R RR RW
W RW WW
There is a 1:2:1 ratio of Red to Pink to White
Therefore
a) 50% chance of being pink
b) 25% chance of being red
c) 25% change of being white

What is the Consumer Product Safety Commission?The CPSC has the authority to recall any consumer product that poses a substantial risk of injury or death to consumers. The CPSC can require companies to recall their products, issue warnings to consumers, and take other appropriate actions to protect the public. Forcing a store to issue store credit is not a typical action that the CPSC would take to protect consumers. While the CPSC can investigate complaints and take legal action against companies that violate safety standards, it does not have the authority to force stores to issue store credit.
Hence, the Consumer Product Safety Commission (CPSC) is a U.S. government agency that is responsible for protecting consumers from unsafe products that are listed in Option C.

Identify the correct statements about transcription(Tnx) and (Tnl) translation in prokaryotes and eukaryotes.
A. Prokaryotes conduct Tnx and Tnl together in the same cellular compartment.
B. Eukaryotes do Tnx in the nucleus and Tnl in the cytoplasm.
C. Tnx and Tnl occur together in the cytoplasm of Prokaryotes and Eukaryotes.
D. Tnx and Tnl both occur in the nucleus in eukaryotes and prokaryotes.
Answer:
A and B
Explanation:
The correct statements about transcription and translation would be that prokaryotes conduct transcription and translation together in the same cellular compartment and eukaryotes do transcription in the nucleus and translation in the cytoplasm.
Prokaryotes generally lack a nucleus and other membrane-bound organelles and as such, their genetic materials lie freely within the cytoplasm. Hence, transcription and translation take place within the same cellular compartment, which is the cytoplasm.
Eukaryotes, however, have a nucleus and other membrane-bound organelles such as mitochondrion. Their genetic materials lie majorly in the nucleus. Hence, transcription takes place within the nucleus. Thereafter, the transcribed mRNA is transported to the cytoplasm where they get attached to ribosome and tRNA and translated into proteins.
The correct options are A and B.

8. occurs in plants that live many years
Explanation:
Plant primary growth starts with successive cell division cycles in undifferentiated cells that form the shoot apical meristem, thereby lengthening roots and stems. The meristems represent a type of tissue involved both in primary and secondary growth. Herbaceous plants have only primary growth and grow in length.
Secondary growth is caused by the growth of the vascular cambium (cambia) and lateral meristems. It is characterized by an increase in thickness of stems and roots. Vascular plants (i.e., plants with a xylem and phloem system) have secondary growth.
In woody plants, the primary and the secondary growth patterns occur across years, and thus they can increase their length (primary tissue growth) and diameter (secondary tissue growth).

1. 4. Do some research and describe two or three scenarios in which it would be preferable to use a stab tube vs. a growth plate. (Hint: What do bacteria use to help them move? Can motility be used to help identify many medically important pathogenic bacteria such as the Enterobacteriaceae?)
Answer and Explanation:
If we want to isolate a species or identify it, we should grow it in a plate with the appropriate media. In this way, it will be much easier to separate a single cell and analyze it by its morphology or study the colony growth. Stab tubes can be used when we want to study, for example, how a bacteria might grow under low-oxygen conditions. Cells might be inoculated in a liquid media or semi-solid media. We might analyze their growth in the deeper parts of the tubes, where oxygen is very low. Grow bacterias cultures in agar plates will also allow us to separate the species of interest form other species present in the culture. We might also compare and study differences between species growth. When growing bacterias on growth plates, they do not last long, as they have more chances of dehydrating. Instead, if we want the culture to survive for a longer-term, we should use stab tubes. Stab tubes are better to study the motility of different species, which might help us to identify certain bacterias of interest.when a true breeding plant with purple kernels was crossed with a true breeding plant with yellow kernels the f1 cob had kernels that were all purple.
