Organisms need energy to conduct essential life activities
Answer:
For several months, weighing and measuring the pups every week
Explanation:
This is to control variables and keep a measurable set of data that can prove or disprove the theory they had developed, and also to isolate cases that can't be attributed to the experiment they had carried out, like puppies loosing weight due to illnesses, or behavioral factors.
Glycolysis, the Krebs cycle and oxidative phosphorylation are the pathways of cellular respiration.
<h3>
Pathway of cellular respiration</h3>
Glycolysis, the link reaction, the Krebs cycle and oxidative phosphorylation are the stages of glucose oxidation. Complete oxidation of one molecule of glucose results in the production of 38 molecules of ATP.
This process also results in the production of 38 molecules of water because the formation of phosphodiester bond between ADP and inorganic phosphate involves the splitting off of a molecule of water so we can conclude that glycolysis, the Krebs cycle and oxidative phosphorylation are the pathways of cellular respiration.

The model describes how cellular membranes i.e. lipid bilayers are organized. Despite the fluidity, lipid bilayers can form certain domains with different characterisrics and compositions. The cell can use different mixtures of lipids to create a 'mosaic' or 'patchwork' of domains.
An example of such domains are so called 'lipid rafts' which are aggregates of certain lipids (mostly cholesterol and sphingomyelins). In these rafts the lateral diffusion of membrane-bound proteins is strongly reduced, thereby forming stable complexes to facilitate, for example, signal-processing and transduction.
Note that a lot about how or why a cell creates these domains is still unknown.
Meaning: A dark color or material obtained by heating organic matter or wood.
