What is the relationship between a mineral and a rock?

1 answer:

4 0

Minerals are composed of multiple elements and rocks are actually made up of minerals. Take quartz for example, it's a mineral that's made up of silicon and oxygen. If we then look at the igneous rock that is referred to as granite, we'll see quartz (the main one), mica(s), and feldspar.

So your answer is B. :)

the difference between a scientific theory and a scientific law because a theory is an in depth explanation of an observed phenomenon. a law is a statement about an observed phenomenon or an unifying concept (i.e.: newtons law or gravity - no explanation on how it works or what it is just that it exists.)

The kernel color in wheat is a continuous trait determined by two additive genes, each with two alleles, that equally contribute

dedylja [7]

Answer:

Phenotypic ratio: 1:4:6:4:1

Punnett square: Below in the explanation box

Frequency distribution: In the attached files

Explanation:

<u>Available data</u>:

The kernel color in wheat is a continuous trait determined by two additive diallelic genes
The red kernels are determined by two genes and two dominant alleles (R1R1R2R2)
The white kernels are determined by two recessive alleles at the same two genes (r1r1r2r2)
R1 and R2 alleles are dominant over r1 and r2, respectively

1st Cross: a true-breeding red plant with a true-breeding white plant
