Pyruvate
Should be your answer
Answer:
B
Explanation:
The rest are being scattered and transmitted however B is going up creating a V shape.
Answer:
It depends on the temperature of the cookie sheet.
Explanation:
If the temperature of a cookie sheet is higher than the container used by Kennya, then the evaporation of water is faster because the water molecules quickly gains the kinetic energy that helps them in the evaporation while on the other hand, if the cookie sheet is not hot enough as compared to the container, the evaporation rate is slower but if both have same temperature so the evaporation is remain the same.
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:
The phenomenon seen by the students is Osmosis.
Explanation:
Osmosis is the movement of molecules from higher concentration to lower concentration through a semi-permeable membrane. This type of movement of molecules occurs in the body cells. When the concentration of molecules is higher outside the cell than the inside, the molecules goes inside the cell through semi-permeable membrane.
