Answer:
It is "The opening of flask is pointed in an unsafe direction"
Explanation:
The students were there in the lab to perform practical without obeying the safety rules. The most reasonable basis for teacher's warning here, in this case, is the flask which is pointed in an unsafe direction. It is not specified whether the flask is containing any chemical or not but even if it is empty, it might just fall and break and create injury to anyone present in the lab because, the students are also not wearing proper laboratory wear in accordance to the safety rules which include lab coats, gloves, eyewear, etc. Also, some Students have not tied their hair and more importantly the flasks carrying liquids are not labeled. All of these things might end up in a critical situation for which the teacher warned students about it all.
Answer:
Regulon
Explanation:
A regulon comprises of a group of operons that are controlled by the same regulatory protein referred to as a regulator which could act as a repressor or activator.
Regulons in bacterial cells are referred to as the fundamental unit of the response system. Regulons are majorly used when referring to prokaryotes that have their genome organized to operons, although this term is not limited to that. The genes that are found in a regulon are arranged into two or more operons at different regions on the chromosome.
I think the answer is molars
Procreation comes from pairing. In different phrases you have 2 codes for each little thing. you have the code from the father and the code from the mother. evaluate the code for blood. you're attentive to that there are 4 varieties of blood variety O, variety A and variety B and variety AB. If mom has 2 codes for her blood, enable us to declare O and O and father has 2 codes for his blood enable us to declare O and A There are a sequence variety of combinatins the 1st mom O can combine with father O, OO The 2d mom O can combine with father A, OA. the 1st mom O can combine with father A, OA The 2d mom O can combine with father O, OO the baby is going to have the two OO or OA. If the baby has OO the the baby has no selection different than to have blood variety O because of fact the expressed phenotype. If the baby has OA the A is dominate and it takes expression. subsequently the only way a recessive allele could be expressed is that if and on condition that there are 2 recessive allele as interior the case of OO. Now do the different combinations mom OO mom OA mom AA mom OB mom BB mom OO can combine with father OO making OO mom OO can combine with father OA making OA mom OO can combine with father AA making OA mom OO can combine with father OB making OB mom OO can combine with father BB making BB The recessive allele is expressed if and on condition that the two codes are recessive. What if mom is dominant A. mom AA mom OA can a recessive allele be produced particular If and on condition that the recessive O of the mother combines with a recessive O of the father. subsequently a mom dominant A might desire to be coded as OA and a father dominant A might desire to be coded as OA. the baby can get carry of mom O blended with the father O and be OO, the recessive. the baby is recessive even whilst the mothers and dads are dominant because of fact the mothers and dads carried the recessive allele. this might ensue if and on condition that the two mothers and dads carry the recessive allele. pass via the mixture mom OA Father AA you will by no capacity get a recessive phenotype expressed
Dust in the atmosphere represents suspension. It is collaborating shaped during colliding and collapsing of the interstellar mediums this is influenced by the gravitational attraction of the atoms and particles in the entitles. Hence, there are three types of nebular namely, are classical nebula, diffuse nebula, planetary nebular and supernova remnants.
