The answer is pyruvate. In the absence of oxygen in
anaerobic respiration, the pyruvate is converted to lactic acid in animals and
ethanol in plants. However, in the presence of oxygen, the pyruvate enters the Krebs
cycle after being converted to Acetyl CoA. Pyruvate is an intermediate product
of glycolysis.

True

Tbh i dont remember sorry :(
What this student thought was happening is called spontaneous generation. Spontaneous generation is a body of thought on the ordinary formation of living organisms without descent from similar organisms
HOWEVER, the student was wrong because it is impossible for organisms to be spawned out of nothing. The organisms appeared due to bacteria on the meat and in the air.
The variation in beak type enables the different individuals in a population to feed on different food sources.
The shape of the beak is key to determining the primary food source of the bird. Certain birds species have specialized beaks, but within populations of those species, there is a variation in beak shape.
This gives the population the ability to respond to changes in the environment and availability of different food sources.
For example, if because of a dry period there is a shortage of fruit, some individuals in the population have the beaks that enable them to feed on other things, survive and leave offspring.
