Answer:
Understanding carbon jargon is all about making up the balance: of the emissions caused, as well as what we can do about them. By knowing about carbon balance and using the right terms, decision-makers in the travel industry can take the necessary measures to set and achieve their carbon goals. Strictly speaking all these terms have different definitions according to the IPCC, the UN body for climate science. However, companies often use them interchangeably, without always specifying their application. As a result, their climate commitments vary widely. This poses a real challenge to distinguish between serious climate action (that is aligned with the Paris Agreement) and so-called ‘greenwashing’. Companies have a responsibility to communicate clearly about their commitments. Sustainability action with all its dimensions should be transparently quantified, documented and audited to be sound. This not only spares you from allegations of greenwashing but also signals that you take your responsibility seriously and offers a real chance to stand out against others in your industry. Here are some commonly used terms and their definitions.

Answer:
Because of the great deal of active transport that occurs here, the <u>proximal convulated tubules</u> of all the nephrons collectively account for about 6% of one's daily resting ATP and caloric consumption.
Explanation:
Proximal convulated tubule is responsible for transport of a very large number of substances mentioned below :
- Sodium bicarbonate
- Sodium Chloride
- Glucose
- Amino acid
- Organic solutes
- K ions are absorbed via paracellular pathway.
- Water is absorbed passively.
Transporters include :
- Na/K transporter
- Na/HCO3 transporter
- Na/glucose
- Na/Amina acids
As a large number or transporters are present in the PCT , large amouny of ATP is cleaved here, and about 6% of daily resting ATP and caloric consumption occurs.
