Answer:
The Bacteria from the 5 kingdom system is divided in two domain in six-kingdom system, these two domains separate all prokaryotic organisms (bacteria) into two new groups: The Archaea bacteria, and Eubacteria or true bacteria.
The archaebacteria are thought to be ancient but live in very extreme habitats such as high or low pH, high temperatures and anaerobic habitat as well where as the eubacteria are more representative of what bacteria is known for. The Archaea domain have cell walls that are different from the Bacteria as their walls do not contain peptidoglycan.

Calculate the following problem. Remember to round off the answer to the nearest whole number, because fractions of a drop are to be avoided when calculating IV drip rates.
Order: 1000 mL of D51/2NS (dextrose 5% in 0.45% sodium chloride) in 8 hours
Available: 1 liter of D51/2NS (dextrose 5% in 0.45% sodium chloride); IV macrodrip tubing 10 gtt per milliliter
The patient should receive ______ gtt per minute.
Answer:
IV flow rate (ggt/min) required for the patient = 21 ggt/min to the nearest whole number
Explanation:
To calculate IV flow rate or the drops per minute, the drop factor is needed.
The drop factor is the number of drops in one mL of solution, and is printed on the IV tubing package.
The formula for calculating the IV flow rate (drip rate) is given as;
IV flow rate (ggt/min) = {total volume (mL) / time (min)} * drop factor (gtts/mL)
From the given values in the question, drop factor = 10 ggt/mL; time in minutes = 8 hours * 60 minutes/hour = 480 minutes; volume of IV fliud = 1 litre = 1000 mL
Therefore, IV flow rate (ggt/min) = (1000/480) * 10 = 20.33
IV flow rate (ggt/min) required for the patient = 21 ggt/min to the nearest whole number

A chromosome’s structure is what it is made of and how it is organized. Its function is what it does. How does knowing about the structure and function of chromosomes help to explain variation in sexually reproducing organisms?
Answer:
Chromosome, the microscopic threadlike part of the cell that carries hereditary information in the form of genes. A defining feature of any chromosome is its compactness. For instance, the 46 chromosomes found in human cells have a combined length of 200 nm (1 nm = 10− 9 metre); if the chromosomes were to be unraveled, the genetic material they contain would measure roughly 2 metres (about 6.5 feet) in length. The compactness of chromosomes plays an important role in helping to organize genetic material during cell division and enabling it to fit inside structures such as the nucleus of a cell, the average diameter of which is about 5 to 10 μm (1 μm = 0.00l mm, or 0.000039 inch), or the polygonal head of a virus particle, which may be in the range of just 20 to 30 nm in diameter.

Assume that one molecule of glucose enters glycolysis in a red blood cell, generating two molecules of glyceraldehyde 3-phosphate. Both molecules enter the payoff phase. One molecule enters the Rapoport-Luebering shunt, while the other does not. How many net molecules of ATP are produced from this molecule of glucose
Answer:
From glycolysis only 8 ATP molecules are obtained
Explanation:
The 8 molecules of glycolysis 6 come from NADH, which is the one that carries these molecules by dissociating, giving NAD + H + as a product.
The metabolic pathway of glucose actually generates 38 ATP, but this value would be the sum of 8 from glycolysis, 6 from the pyruvic acid pathway and 24 from the krebs cycle ... These last two pathways are part of cellular respiration .

Which one of the following steps in elongation is directly dependent on ATP or GTP hydrolysis? Peptide bond formation Movement of the ribosome 3 bases toward the 3’ end of the mRNA Loss of the sigma subunit Binding of initiator tRNA to appropriate AUG codon Translation termination
Answer:
Movement of the ribosome, 3 bases toward the 3’ end of the mRNA
Explanation:
Movement of the ribosome, 3 bases toward the 3’ end of the mRNA - This process can also be referred to as translator in the ríbosome.
This translocation process requires GTP hydrolysis.
Translocation occurs by the action of the enzyme elongation factor which uses the energy resulting from GTP hydrolysis to move to the A site on the small subunit forcing the tRNA and the mRNA to move a distance of one codon ( 3 bases) through the ribosome.

The introduction of certain animals from Europe, especially horses, had a positive effect on some American Indian communities. However, European cattle and other livestock sometimes caused more harm than good. In some cases, livestock entered the unfenced fields of American Indian farmers, eating and trampling their crops. Unlike European farmers, many American Indian farmers had never learned how to fence in their fields because it had never been necessary. The American Indians in the Spanish colony of New Spain in Central and North America experienced this problem. Antonio de Mendoza, the first viceroy of New Spain, wrote these words to the Spanish king in the 1530s: May your Lordship realize that if cattle are allowed, the Indians will be destroyed. How could the Spanish have helped American Indians adapt to the new species of livestock?
Answer:
Explanation:
To reduce the incidents of destruction of field by this animals the Spanish could have helped adapt by taming the animals, the animals can be kept in a ranch where they would be controlled to prevent them from entering fields.
The American India could be enlighten through orientation about how to keep their farms save from invasion by this pest animals.
The India should be enlighten about the animal and its mode of operation and how to prevent the entry of this animal pest into their field. This will help them adapt to animal.
With this the India would be able to feel loved and start adapting to the new changes.
Answer:
The Spanish colonists could have helped the American Indians adapt to the new species of livestock by teaching them to fence their fields to protect their crops. Furthermore, they could have taught American Indians how to use livestock for food, trade, and labor.
