Density review
A B
What is the density of a piece of wood that has a mass of 25.0 grams and a volume of 29.4 cm3? d = .85 g/cm3
A piece of wood that measures 3.0 cm by 6.0 cm by 4.0 cm has a mass of 80.0 grams. What is the density of the wood? Would the piece of wood float in water? (volume = L x W x H) d = 1.11 gm/cm3
I’d say 4 because running a mile in 6 minutes is better than what most people can do and that will really make your heart rate go up
The term phenotype in a more specific context to describe the collective expression of the genotype in conjunction with the environment on a plant's observable characteristics.
<u>Explanation</u>:
- Phenotype, any of the measurable features of an organism arising from its genotype association (total genetic inheritance) with the environment. Behaviour, biochemical properties, colour, form, and scale are examples of measurable characteristics.
- An allele is another type of one gene. A phenotype triggered by the expression of a gene or group of genes is the external manifestation of a human trait.
- A trait is an attribute unique to an organism. The genotype's external expression is called the phénotype.
Starches are more than chains of sugar granules strung together. In the case of corn starch, it is actually millions of these molecules packed into very discrete granules, which cannot be seen by the naked eye. Putting corn starch into cold water, nothing happens because cold water does not dissolve these granules. Putting it into hot water (like cooking gravy) however, these granules dissolve and create bonds between the water and the starch.
