Answer:
All their descendants will be heterozygous for the skin color, Bb, expressing blue skin.
Explanation:
<u>Available data</u>:
- Smurfette has light blue skin
- Her family is a "true bred" or "purebred" line.
- She married a boy who has light yellow skin
- blue skin is the dominant trait expressed by the B allele
- yellow skin is a recessive trait, expressed by the b allele
Cross: Smurfette x Husband
Parentals) BB x bb
Gametes) B B b b
Phenotypes) blue skin yellow skin
Punnett square)

b Bb Bb
b Bb Bb
F1) 100% of the progeny will be heterozygous for the skin color, Bb
100% of the progeny will be blue-skinned.
Note: Although the progeny is blue-skinned, they are not true-bred anymore.
When you are mining for something you are using tech to break through the rocks you are causing a lot of erosion by break down the rocks. Plus you are causing a lot of radioactive substance which can harm the environment.
Hopefully that answers your question.
Answer:
A pteridophyte is a vascular plant that disperses spores. Because pteridophytes produce neither flowers nor seeds, they are sometimes referred to as "cryptogams", meaning that their means of reproduction is hidden. Ferns, horsetails, and lycophytes are all pteridophytes.
Explanation:
Organisms are classified and divided in a community based on the modern classification system that was published by Carolous Linnaeus in the 18th century.
This criteria is also known as the Linnean system of classification, where the organisms are classified according to the following: Species, Genus, Family, Order, Class, Phylum and Kingdom.
Answer:
Collections of nerve cell bodies in the peripheral nervous system are called <u>ganglia.</u>
Explanation:
Ganglia are structures enclosed in a tissue sheath, which contains cell bodies of neurons. They also contain dendrites that make synaptic connections between neurons, transporting electrical impulses, connecting the brain with specific organs. They are part of the peripheral nervous and are responsible for connecting the peripheral nervous system with the central nervous system, both in an efferent sense (from the central nervous system to the sensory organs), and afferent (from the sensory organs to the central nervous system).
