Susan finally visits her physician after feeling tired, dizzy, nauseous, and feverish for a long time. During her physical, the doctor draws whole blood to do a complete blood count and white cell differential. How might this help in making a diagnosis?
Answer:
it helps to find out the type of bacteria affecting the red blood cells
Feeling dizzy, nauseous and feverish for a very long time might be due to low levels of hemoglobin or it can be due to decrease in white blood cells or platelets count. To diagnose the problem, it might help by doing whole blood count.
What is dizzy?Dizzy means a whirling sensation in the head which makes to fall.
What is nauseous?Nauseous means the feeling of vomiting.
What is feverish?Feverish means a rise in temperature than normal.
What is hemoglobin?Hemoglobin is the red colour pigment present in red blood cells.
What are white blood cells?White blood cells are the cells which helps in immunity.
What are platelets?Platelets are the larger cells which helps in clotting of blood.
What is diagnose?Diagnose means to identify.
What is problem?Problem means a harmful situation which is to be solved.
What is whole blood count?Whole blood count is the blood used to evaluate overall health.
Therefore by the physical examination, whole blood count can help in diagnosis of many disorders like anemia, tuberculosis, leucopenia etc.

How could you experimentally test whether herds of African antelope affect the abundance of plants on which they graze?
Answer:
For the given case, one would fence off some part of land with antelope and the plants they feed on and similarly fence off some other part of land with no antelope. After that comparative analysis is done with the two experimental plots to check that whether the herds of African antelope influences the abundance of plants they consume. An essay in which the two things are contrasted and compared is termed as comparative analysis.

All of the following set the Mannerists apart from other painters except.
A. unnatural color combinations.
B. heavy use of diagonal lines.
c. deliberately unbalanced compositions.
D. visual distortion.
SUMIT
Answer:
B. heavy use of diagonal lines
All of the following set the Mannerists apart from other painters except heavy use of diagonal lines. Thus, the correct option is B.
What are Mannerists?Mannerist may be defined as a person or an individual who is associated with the working style of Mannerism. Mannerism describes the style of the paintings and bronze sculptures that emerged in the later years of the Italian High Renaissance around 1520. It is a style of European art.
During the activity of this art, all the Mannerists set some combination of representing their art in better form. This includes unnatural color combinations, visual distortion, deliberately unbalanced compositions, etc. Mannerism is an affected adherence to a particular style or mode or manner.
Therefore, all of the following set the Mannerists apart from other painters except heavy use of diagonal lines. Thus, the correct option is B.

Argue whether or not pandas are at the top of their food chain in the following scenario.
Pandas are herbivores that live in the mountainous regions of China. They are peaceful and docile and spend about 18 hours a day eating bamboo. They have only one natural predator: the leopard. However, adult pandas are so large that they are never hunted. Leopards will eat only baby pandas that are left alone, and this occurrence is very rare. Most baby pandas are killed accidentally when their mothers roll over.
In this ecosystem the Leopard usually eats the Giant Panda bear cubs because the adult pandas are very intimidating out in the wild because of their size. The Leopard is then eaten by the Bengal Tiger which in this situation is the Tertiary Consumer and is at the top of the Panda Bears food chain.
The Panda comes under the secondary consumer, as it uses photosynthesis to produce its food – Bamboo. Cubs become a prey to other animals such as Leopards and tigers, which are known as the primary consumer. However adults intimidate other predators because of their great size.
What do you think happens when there is
not enough food available for all of the

Answer:
Competitiveness between species will increase
Explanation:
When there is less resources available to a species that means no every animal can survive so the species will have to compete for survival

The chart lists a few structural characteristics of viruses.
1. Viruses are extraordinarily small in size.
2. Viruses are not specific to their hosts.
3. Viruses contain either DNA or RNA as genetic material.
4. Viruses lack cellular organization.
Based on the information, enter the number of the characteristic that explains why viruses are unable to reproduce on their own.
“The virus cannot reproduce itself outside the host because it lacks the complicated machinery that a [host] cell possesses.” The host's cellular machinery allows viruses to produce RNA from their DNA (a process calledtranscription) and to build proteins based on the instructions encoded in their RNA.

What is the structure of prokaryotic chromosomes
Answer:
1. Prokaryotic chromosomes are found in the nucleoid of prokaryotic cells, and they are circular in shape.
Unlike eukaryotic cells, prokaryotic cells don’t have a membrane-bound nucleus. Instead, their genetic material can be found in a region of the cytoplasm called the nucleoid. A prokaryotic cell typically has only a single, coiled, circular chromosome. However, there are a few prokaryotes that have more than one—Vibrio cholerae, the bacterium that causes cholera, has two circular chromosomes.
All 3D models in the page have loaded
Prokaryotic Chromosome
Prokaryotic cells typically have a single, circular chromosome located in the nucleoid.
Download DNA Lab Activities
2. Each chromosome contains a molecule of DNA that is supercoiled and compacted by nucleoid-associated proteins (NAPs).
Prokaryotic cells may have only one chromosome, but that one chromosome is a very long DNA molecule that must be condensed to fit inside a tiny space. In a eukaryotic cell, DNA wraps around clusters of histone proteins. However, most prokaryotic cells don’t use histones to help with DNA storage. (Some Archaea do, but they are the exception, rather than the rule.)
Like eukaryotic DNA, prokaryotic DNA undergoes supercoiling, but it is not wound around histone clusters first. Supercoiling uses the application of tension to twist a DNA molecule, so it wraps around itself, creating loops.
The folding of prokaryotic DNA is facilitated by nucleoid-associated proteins (NAPs) instead of histones. NAPs are proteins within the nucleoid that can bind to the DNA molecule, introducing bends and folds, and they are involved with processes such as DNA replication and transcription.
3. Prokaryotic cells are haploid, meaning they do not have chromosomes that occur in homologous pairs.
Most prokaryotic cells have just one chromosome, so they are classified as haploid cells (1n, without paired chromosomes). Even in Vibrio cholerae, which has two chromosomes, the chromosomes are unique from one another. That is, they are not a homologous pair, because they don’t contain the same genes in the same locations.
Many prokaryotes, such as bacteria, reproduce via binary fission. This is a method of asexual reproduction that is similar in its end result to mitosis—two daughter cells result, each with the same number of chromosomes as the parent cell. However, when bacteria undergo binary fission, no mitotic spindle forms. In addition, the replication of the prokaryotic cell’s chromosome can occur during the fission process.
4. Prokaryotic cells can also carry small molecules of DNA called plasmids.
Plasmids are small, circular DNA molecules that contain the cell’s nonessential genes. Although plasmids can occur in a variety of sizes (ranging from around a thousand base pairs to hundreds of thousands), they usually only have a small number of genes. Antibiotic resistance is a trait that is frequently attributed to genes on plasmids.
In addition to their single chromosome, prokaryotic cells often have small, circular DNA molecules called plasmids.
The genetic material of plasmids is separate from that of the cell’s main chromosome, and they can replicate independently of that chromosome. When a prokaryotic cell with a plasmid divides, the daughter cells each receive a copy of the plasmid, along with its regular chromosome.
5. Prokaryotic and eukaryotic chromosomes differ in their shape, size, number, and location within the cell.
Here’s how the characteristics of eukaryotic and prokaryotic chromosomes compare.

Shape Linear Circular
Size Large Small
Number Multiple Single
Location Nucleus Nucleoid (region in cytoplasm)
Storage proteins Histones Nucleoid-associated proteins
