Answer:
Something studied on the molecular level is the water.
Explanation:
Water is a molecule formed by two hydrogen atoms and one oxygen atom, whose chemical representation is H₂O. It is a molecule whose polarity makes it a universal solvent of other polar molecules.
The molecular level corresponds to the level of organization where two or more atoms unite to form molecules or substances, united by chemical bonds. H₂O is studied at this level due to its chemical structure.
With respect to other options:
- <u><em>Hydrogen and oxygen</em></u><em> are atoms, and correspond to the level of atomic organization.</em>
- <u><em>Protons</em></u><em> are particles that are part of an atom, and correspond to the subatomic level.</em>
A neutron has no charge
<em>NEUT</em>RAL = NONE
well thats how I remember it anyway
SO ITS NUMBER 2
Answer:
2a and -5a
8 and -4
hahahah they are separate from each other
2a and -5a simplifies to -3a
8 and -4 simplifies to 4
Explanation:
hope this helps!
Answer:
There's 25% probability that their next child will be normal, and 75% of it being a dwarf.
Explanation:
Achondroplasia (A) is a dominant trait.
Two achondroplastic dwarfs (A_ x A_) have a dwarf child (A_) and a normal child (aa). The second child must be aa because if it had a dominant allele it would also be dwarf.
The only way for two achondroplastic parents to have a normal child is that <u>they are both heterozygous (Aa) for this gene.</u>
The cross Aa x Aa would produce the following offspring probabilities:
- 1/4 AA - dwarf
- 2/4 Aa - dwarf
- 1/4 aa - normal
So there's 1/4=25% probability that their next child will be normal, and 3/4=75% of it being a dwarf.
Answer:B
Explanation:
Selective breeding is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits by choosing which typically animal or plant males
