Answer:

↓

Explanation:

I can't really read what you have typed, but the subscripts are the little numbers such as this 2 in H₂O. So using the blue pen, I'm assuming you would circle the little numbers. The coefficients are the numbers in front of the elements so from what I can read, in 2HCl the 2 would be circled in the orange. So in a simple way the subscripts are the tiny numbers that are at the bottom (usually after elements), and the coefficients are normal numbers in front of the whole element.

Hopefully that makes sense! :)

In a certain plant, the allele for red flower color (R) is dominant over the allele for white flower color (r). A cross is perfo

Iteru [2.4K]

Answer:

Rr and rr

Explanation:

The genotypes of the parents would be heterozygous red (Rr) and true-breeding white (rr).

<em>Since the allele for the red flower color (R) is dominant over that of the white flower color (r), for a cross to produce both red and white flower color plants, the red parent must be heterozygous (Rr) and the white parent true-breeding (rr). </em>

Rr x rr

Rr Rr rr rr

Rr = red

rr = white

If the red parents is true-breeding

RR x rr

Rr Rr Rr Rr

All their offspring would be red without any white flower color.

Hence, the genotypes of the parent are Rr and rr.

Which statement best describes an igneous intrusion?

Fiesta28 [93]

The right option is C. Magma is injected into surrounding rock forming an igneous intrusive.

An igneous intrusion is a formation in which magma rises up below the surface of the Earth and intrude into other rocks located above it forming an igneous intrusive and leaving them in a dome shape. The magma cools and solidifies before it gets to the surface and it is later exposed as the broken sedimentary rock on top of it gradually wears away. The two types of igneous intrusion are; intrusive and extrusive rocks.
