Strep throat and bacterial pneumonia are examples of
The correct answer is a. bacterial communicable diseases.
Strep throat is a bacterial infection which has symptoms such as sore and scratchy throat. The causative agent of strep throat is <em>Streptococcus pyogenes </em>and gets spread by contact by the secretions of the respiratory tract of the infected person if the person sneezes or coughs.
The bacterial pneumonia is commonly caused by <em>Streptococcus pneumoniae. </em>The bacterial pneumonia is a community acquired pneumonia. The most common way it is caused when the bacteria aspirates from the oral cavity or by breathing infected air droplets having pneumonia. The bacteria can enter the bloodstream and deposits in the lungs causing pneumonia.
If a doctor wanted to find out the number of white blood cells in a patient's blood, he or she would order a(n)
The correct answer is d. complete blood count.
White blood cell count test is used to measure of the white blood cells in the patient's body. This test is included in the complete blood count test. There are different types of white blood cells present in the body and each of it has a specific percentage .
D = m/V
m = 75g
V = 4 x 4 x 4 = 64 cm^3
d = 75/64 = 1 11/64 g/cm^3
The answer for this is legumes.
Answer:
b. the ocean regulates climate
Explanation:
Answer:
No, there are multiple ways in which different mutations in the same gene can cause the same phenotype
Explanation:
Several different mechanisms of mutation can lead to the same phenotype. For example, lets say our phenotype is that flies have white eyes, and we know that this occurs in one particular gene that normally makes the eye colour red. (the red gene)
These mutations likely rendered the red gene ineffective (as the eyes are not red). However, this could happen in a variety of ways.
- There could be a single base deletion in the first exon of the mRNA, changing the reading frame of the protein and messing up the entire sequence (a frame shift mutations)
- The entire gene could be deleted
- A single base could be substituted in an important site of the gene, for example, one which translates into a catalytic residue or binding site in the protein
- There could be an inversion at the promoter region of the gene, such that a transcription factor can no longer bind to transcribe the gene.
There are countless other ways in which a mutation could have been caused. Therefore, just because we know the same gene is affected does not mean that we can assume the mutations are identical.
