Answer:
Around 25-30 gigatons.
Explanation:
Although natural processes do produce much more carbon dioxide than humans, its a delicate balance and all of that carbon dioxide is absorbed back. However, when humans arrived, they disrupted that balance, and even with the relatively small amount it is creating big problems.
Answer:
The lactose present prevents the production of lactase
Explanation:
This question is describing a set of genes in bacteria called LAC OPERON. Lac operon controls the production of lactase, which is the enzyme that digests lactose. However, this gene can be regulated at the transcription level i.e caused to be transcribed or not depending on certain factors.
According to the question, lac operon, which regulates the production of enzymes will be transcribed and subsequently translated i.e. turned on when there is a substrate (lactose) that the produced enzyme will work on. However, when there is no need of the lactase enzyme or there is absence of lactose (substrate), the lac operon gene is turned off.
Note that, the statement that "The presence of lactose prevents the production of lactase" is not correct.
Answer:
See below.
Explanation:
Other than Carbon Dioxide (CO₂), two carbon compounds found in plants are :-
- Glucose (C₆H₁₂O₆)
- Pyruvic Acid (C₃H₄O₃)
It is b) angle B.
The opposite angles of opposite sides are proportional to each other. So the smallest side’s opposite angle will be the smallest angle, and in this case, since the largest side is 12, the opposite angle, B, will be the largest angle.
