Tju [1.3M]3 years ago
3 0

Answer:

<u>A. They are organic molecules that all contain carbon.</u>

Explanation:

All known life on earth is carbon-based. Most molecules used as building blocks are organic i.e. consisting of based on carbon. This means that they consist of atoms of carbon, hydrogen, oxygen with other variations like nitrogen.

Some macromolecules include glucose-based polysaccharides, amino-acid based proteins and lipids consisting of glycerol and fatty acids.

Which of the following situations or phrases most accurately describes the citric acid cycle?
Bond [772]

The correct answer is: B) "All roads lead to Rome"

Citric acid cycle also called tricarboxylic acid (TCA) cycle and Krebs cycle is a central process in cellular respiration. Citric acid cycle that connects carbohydrate, fat, and protein metabolism so “all the roads” from the different metabolic pathways come to this cycle.

Acetyl-CoA which is produced through the oxidation of pyruvate (pyruvate is a product of glycolysis) enters the cycle which then produces reduced electron carriers NADH, FAD2 and energy molecule ATP. These electron carriers will then pass their electrons into the electron transport chain and, through the process of oxidative phosphorylation, will produce more ATP.

Muscular exercise presents a dramatic test of the body's homeostatic control systems because it results in large _____.
kicyunya [14]

Muscular exercise presents a dramatic test of the body's homeostatic control systems because it results in large amounts of heat production.

Homeostatic control systems- A body's physiological ability to maintain a steady internal environment in response to changes in the external environment is known as homeostasis.

Heat Production- The term "thermogenesis" refers to the process through which energy is lost by producing heat with specialization.

Energy- In biology, cells frequently store energy in macromolecules, especially lipids and carbohydrates (sugars). When chemical bonds are formed, such as during the redox reactions of cellular aerobic respiration, energy is released.

Redox Reactions- A reaction that happens when an oxidizing material and a reducing substance come into contact.

Which method do you think best represents energy flow through ecosystems? Why?
pentagon [3]

Answer:

The circle of life, in which energy flows into the world from the sun, giving plants that energy to live.  All of the organisms in an ecosystem are chemical machines driven by the energy captured in photosynthesis. The organisms that first capture energy, the producers, include plants, some kinds of bacteria, and algae. All other organisms in an ecosystem are consumers.

The plants energy will then be transferred to a small animal, most likely a rabbit or maybe a mouse; depending on the plant. The small animal will then be eaten by a bigger more dominating animal like an eagle or a snake. It just goes on and on. The eagle or the snake will get eaten by a bigger animal or will decompose into the earth giving the soil and plants around it that same energy.
