Lichens that colonize bare rocks are an example of a pioneer

irina [24]

Answer:

C. A hillside that has been cleared by a volcanic eruption.

Explanation:

Pioneer species are hardy species which are the first to colonize barren environments or previously biodiverse steady-state ecosystems that have been disrupted, such as by fire or other natural disasters. Some lichens grow on rocks without soil, so may be among the first of life forms, and break down the rocks into soil for plants.

Hope this helps!

Ahat [919]

<h2>Human Body Systems</h2>

Explanation:

Cardiac and skeletal muscle and cardiac(heart) are both striated in appearance, while smooth muscle isn't.
Both Cardiac and smooth muscle are automatic while skeletal muscle is deliberate.
Cardiovascular muscle is likewise an automatic muscle yet is progressively associated in structure to skeletal muscle, and is discovered uniquely in the heart.
Smooth muscles move nourishment through the stomach related tract.
In one's eye the pupillary sphincter muscles is answerable for contracting the size of the student.
Smooth muscle developments keep up the supply routes' breadth. Smooth muscle controls wind stream in lungs.
Heart muscles are striated not normal for smooth muscles.

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).

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).

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.
