Medicine is that branch of science that helps us to know a human body and treat it in the right way to stay healthy as long as possible. So there are different factors which intrigue a person to chose medicine as their career of choice.
<h3><u>Explanation:</u></h3>
Medicine practically deals with knowledge about different disabilities as well as diseases that can attack a person to disturb his normal way of life. And for knowing the diseases, the medical practitioner needs to the normal functions of human body too. This fact attracts many person who are keen to know which mechanisms are going inside their body without even their knowledge.
Medicine also deals with different chemicals and compounds that are actually helpful in curing a disease. Thus, helping a person who is suffering from so much of pain because of a disease is so satisfying. There are many doctors who actually help different poor people who can't afford a good medical treatment. So medicine as a career is full of knowledge and experience, so worth taking as well.
Answer:
The correct answer is option B, that is, promoter, operator, gene.
Explanation:
In a prokaryote, just in front of the operator, the promoter is located, and just in front of the structural genes, the operator is located. All these in combination give rise to an operon.
Any gene, which codes for an enzyme or a structural protein is termed as a structural gene, in the lac operon, a structural gene codes for three distinct kinds of enzymes. A short sequence of DNA is situated just in front of the structural gene, which is known as the operator. An operator functions as a switch for transcription, that is, it monitors whether the process of transcription will take place or not.
Just in front of an operator, a sequence of a promoter is present, and for the transcription and translation of all the structural genes, the RNA polymerase needs to combine first with the promoter. In case, if no transcription is to take place, then the operator allows the repressor to bind with it and prevent the attachment of RNA polymerase with the promoter. Hence, the correct sequence of a prokaryotic operon is a promoter, operator, and gene.
Answer:Plants - cell wall forms.
Animals - cleavage furrow forms
Explanation:Cytokinesis occurs in mitosis and meiosis for both plant and animal cells. The ultimate objective is to divide the parent cell into daughter cells.
In plants , this occurs when a cell wall forms in between the daughter cells.
In animals , this occurs when a cleavage furrow forms. This pinches the cell in half.
<span>If the PH and temperature changed significantly beyond the enzyme optimum level it will become denatured and then the enzyme would not work.
The Enzyme is a biological catalyst which speeds up a reaction. The Enzyme has molecules which act upon as substrates and then it converts those substrates into different molecules which are called products.
The study of the enzyme is known as enzymology, and they are well known to catalyze more than 5,000 biochemical reaction types.</span>
