The process of genetic engineering may include either four or five steps. The diagram represents the five-step process.

Which best describes step 2?

A) Restriction enzymes cut the DNA into fragments; the fragments join with the host DNA to create recombinant DNA.

B) Recombinant DNA is inserted into a biological vector; the vector houses the recombinant DNA and can produce copies of DNA for itself and the recombinant DNA.

C) Cloning of the recombinant DNA occurs; the DNA is cloned in the biological vector to create more DNA for use in the host.

D) Recombinant DNA is inserted into a mechanical vector; the mechanical vector allows the DNA to be inserted into the DNA clone for use in the host.

Answer:

I think the answer is C

Explanation:

C

Lucy was a bipedal hominid, and her discovery provided evidence that bipedality preceded the evolution of larger brain size and extensive tool use.

It is one of the most complete fossils ever found. Because it is a very complete skeleton, compared to the fragments that are usually found, Lucy allowed scientists to better understand human ancestors and study size, shape and locomotion.

Whit this information, we can conclude that Lucy was a bipedal hominid, and her discovery provided evidence that bipedality preceded the evolution of larger brain size and extensive tool use.

The base pair sequence that could be produced in DNA replication is  AGTCAT, UCAGUA. The correct option is c.

The DNA sequence is the sequence or pairing of DNA bases. RNA and DNA both are genetic materials and both are made up of nucleic acids made up of deoxyribose acid and iron is made up of ribonucleic acid.

DNA and RNA both contain four bases that are joined with hydrogen bond RNA contain uracil in the place of thymine and DNA contain timing all other bases are same.

The base pairs are complementary to each other: Thymine: Adenine and cytosine: guanine.

But in RNA, it is uracil with adenine. Guanine and cytosine are the same. So the adjacent base pairs will be:

AGTCAT

UCAGUA

Therefore, the correct option is c. AGTCAT, UCAGUA

Answer:

7250 WBC/ml

Explanation:

The mean of any value is the average of a certain amount of given values. When this is taken into cognizance, to get the mean White Blood Cell count of the population, given two ranges, is to add and divide both together. This gives us

10,000 + 4,500 = 14,500 WBC/ml

The mean then is

14,500 / 2 = 7250 WBC/ml

Therefore, the mean White Blood Cell count in the population is 7250 WBC/ml

Answer:

Global warming is the increase in the earths atmosphere from several things. Pollution is the main cause of this. "Global warming" is the overall effect and "climate change" is what is happening to our planet currently.The average global tempature is increasing at a very high rate and is getting worse very quickly.  Scientists say that unless we slow down global-warming emissions, average U.S. temperatures could increase by up to 10 degrees Fahrenheit over the next century. Pollutants can last over a year in our atmosphere these pollutants trap the heat and cause our atmosphere to become warmer (green house effect). The biggest source of climate change is the burning of fossil fuel :coal, petroleum, natural gas, oil shales, bitumens, tar sands, and heavy oils.

Chemical energy

Explanation:

Energy, potential energy, is stored in the covalent bonds holding atoms together in the form of molecules. This is often called chemical energy.

The energy stored in bonds between atoms is B. chemical energy.

Chemical energy is the energy that is stored in the bonds between atoms. When these bonds are broken, the energy is released. This energy can be used to do work, such as powering muscles or generating electricity.

Mechanical energy is the energy of motion. Electrical energy is the energy of electrons. Neither of these types of energy is stored in bonds between atoms.

It is LMAN leison because lateral magnocellular nucleus of the anterior nidopallium (LMAN) function in producing modulatory during song development in song birds .

Lesion means damage in organ or tissue that function

A damage in the organ or tissue of LMAN cause difficult in song learning development in song birds because the LMAN will not be able to perform it's function due to those damages and there is less song variability.

Answer:

a) Rhonda might have anemia

b) Rhonda feels tired because her blood is unable to transport enough oxygen

c) Iron is required by the blood cells for the formation of hemoglobin

Explanation:

a. A low hemoglobin level is referred to as anemia or low red blood count. From her blood test results, Rhonda has below normal levels of hemoglobin. This indicates she might have anemia.

b) The primary work of hemoglobin in blood is to transport oxygen from the lungs to the cells that need it for metabolic activities. When the ability of the blood to transport blood is impaired due to low hemoglobin levels, fatigue and tiredness sets in since enough oxygen is not present for cellular respiration and production of ATP.

c) Hemoglobin is an iron-rich protein that helps red blood cells carry oxygen from the lungs to the rest of the body. If iron intake is not sufficient, anemia could result. Therefore, it is important that iron-rich meals are incorporated into our diet.

So her MD would need to know how much of iron she has been having in her diet.

Answer: B. They are located and bind the steroids in the cytoplasm

Explanation: Steroid hormones are a class of organic compounds, typically lipids. They bind to protein receptors in the cytoplasm or nucleus of the target cell and thus, their receptors are located inside target cells where they function as ligand-dependent transcription factors. This is to say that hormone-receptor complex formed on binding to DNA activates specific genes that increases production of proteins.
