Answer:
What did researchers learn from terra preta?... Because terra preta is loaded with so-called bio-char -- similar to charcoal -- it also can pull substantial amounts of carbon out of the increasing levels of carbon dioxide in the Earth's atmosphere, helping to prevent global warming.
How is bio-char different from the traditional Amazonian method of creating terra preta? Terra preta owes its characteristic black color to its weathered charcoal content, and was made by adding a mixture of charcoal, bone, broken pottery, compost and manure to the low fertility Amazonian soil. ... Terra preta soils were created by farming communities between 450 BCE and 950 CE..
The BBC's Unnatural Histories presented evidence that the Amazon rainforest, rather than being a pristine wilderness, has been shaped by man for at least 11,000 years through practices such as forest gardening and terra preta.

Answer:
1. When the number of calories a person consumes is equal to the number of calories he or she burns in a day, that person's body is in Energy Balance.
2. Someone who is in Positive Energy Balance eats more calories in a day than he or she bums.
3. Negative Energy Balance occurs when the number of calories a person bums in a day is greater than the amount he or she consumes.
4. Weight management involves applying strategies that allow someone to keep his or her body weight within a healthy.
5. The Basal metabolic rate is the amount of energy uses in order to perform its basic physiological functions.
6. The Thermic effect of food refers to the number of calories burned in order to digest absorb, metabolze, and store food.
7. The Lean body mass refers to his or her total body - fat mass.
Explanation:
This group of statements are related to body weight, the balance between the energy we consume through food and all the energy we burn through excercise and different activities, such as only mantaining our body temperature and normal processes.
The answer would be lipids, they are a type of biomolecule and a nucle is an organelle
Answer:
The correct answer is a. can be activated by the release of epinephrine.
Explanation:
Epinephrine is a hormone and neurotransmitter naturally secreted by the body through the adrenal glands, synthesized and stored in the adrenal medulla and released into the systemic circulation. Epinephrine is a non-selective adrenergic agonist, stimulating alpha1-, alpha2, beta1, and beta2-adrenergic receptors. The systemic actions of catecholamines are mediated by the binding of these compounds to plasma membrane receptors, of the GPCR type widely distributed throughout the body and known as adrenergic receptors, which are activated by the catecholamines adrenaline (epinephrine) and noradrenaline . These receptors cause different effects depending on the G protein subtypes to which they are associated and the signal transduction mechanism linked to the specific G protein.
