You want examples? Here they are:

Animal studies:

1. Test whether dogs react more to smell or to their owner's attention to an object: they have to choose between a plate that smells more of food and a plate their owner paid attention to

2. Test whether dogs can follow their owner's gaze: owners call the dogs and then look somewhere and we see whether dogs follow this gaze (look up gaze-following, it's important for learning!)

3. Test whether birds can use tools: give bird a long stick and a box with a peanut inside and see if they can use the stick to get the peanut out

4. Test whether vision can develop in the absence of stimulus: bind kitten's eyes at birth and see if they'll develop perfect vision (they didn't...)

What is the basic unit of structure and function in plants, animals, and bacteria?

padilas [110]

Answer:

The cell is the basic structural and functional unit of life. Cells are independent, single-celled organisms that take in nutrients, excrete wastes, detect and respond to their environment, move, breathe, grow, and reproduce.

Which of the following pieces of evidence would best support the argument that humans are more evolutionarily related to fish th

Phoenix [80]

Answer:

The early stages of embryo development in fish and humans look strikingly similar while insects develop very differently compared to both fish and humans,

Explanation:

It tells you that fish and humans have very similar embryo development (fetus development) while humans and insects develop very differently. Therefore, that supports the argument that humans are more like fish than insects.

where the carbon atoms of acetyl coa end up and where the energy that was stored in acetyl coa ends up. krebs cycle

ruslelena [56]

Since each glucose molecule produces two acetyl-CoA molecules, the Krebs cycle must be completed twice to produce the four CO2, six NADH, two FADH2, and two ATPs.

Catabolic reactions occur within cells during cellular respiration. It is a biochemical process by which waste materials are removed and nutrients are broken down to generate energy, which is then stored in the form of ATP. The process of aerobic respiration needs oxygen.
The Krebs cycle, also known as the citric acid cycle, is the last step of oxidation for amino acids, lipids, and glucose.
Other than glucose, many animals rely on other substances for energy.
Protein's metabolic byproduct, amino acids, are deaminated and converted to pyruvate and other Krebs cycle intermediates.
They begin the cycle and are broken down, for example. On deamination, alanine turns into pyruvate, glutamate into -ketoglutarate, and aspartate into oxaloacetate.
Acetyl CoA is created when fatty acids are -oxidized and enters the Krebs cycle. It is the primary mechanism through which cells produce ATP. Complete nutrient oxidation results in the production of a significant amount of energy.
