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.
Answer:
Aseptic technique is important in the microbiology laboratory health care industry because it reduces the contamination risk that can have serious implications on the health of a person.
If aseptic procedures are not performed in the Microbiology laboratory and health care industry then there would be chances of getting the disease because in health care industries pathogenic samples from patients are processed which can be transferred in the employee while processing if correct aseptic technique is not used.
Aseptic procedures include wearing lab coats and other protective suits while working which cover all body and give protection from entry of pathogens. Sterilization of surface where work is going on, proper sterilization of all pathogenic cultures.
Therefore aseptic procedures are important to avoid contamination in the microbiology laboratory.

Answer:
The correct answer will be- true.
Explanation:
The endo-membrane system is the system which is formed by the group of the membranes and organelles. These membrane and organelles are considered endomembrane as they work together to perform the inter-related functions like the packaging, modification ad transport of the lipids and the proteins.
This system comprises of the nuclear membrane also as the outer nuclear membrane is continuous with the endoplasmic reticulum (organelle) directly and helps the synthesis and modification of the proteins and lipids. other organelles are the Golgi apparatus, vesicles, lysosomes and endosomes.
Thus, option-true is the correct answer.
Answer:
<em>Hey there!</em>
3) Well injection is usually done through the vein because they need the substance to go into the blood.
4) Some people believe that the heart is on the left side because its the left ventricle and atrium responsible and when people hear left they think the heart is on the left.
5) People living in high altitudes don't get as much oxygen so their bodies evolved into carrying ,more RBC so more oxygen is carried into their bodies.
<em>Hope this helps :)</em>
