Answer: Option A.
The electrons are being shared between the carbon and oxygen atoms.
Explanation:The electrons are being shared between the carbon and oxygen atoms because each oxygen share four electrons with the central carbon, therefore carbon atoms have 8 electrons that is shared with oxygen. The oxygen have two shared pairs in double bond and two lone pairs in non bonding. Carbon and oxygen form covalent bond. This satisfies the octet rule because the electrons are shared in both oxygen and carbon octet.
In a carbon dioxide molecule (O=C=O),
You observe a cell in a stained section of connective tissue. The cell has an indented nucleus and obvious cytoplasmic granules. Upon further testing, you determine that the granules contain histamine. This cell is most likely a(n) _____.
mast cell
Answer:
Nutrients and other materials from the environment are absorbed through mycelia. The branching mycelia have a high surface-area-to-volume ratio which allows the absorption of nutrients to be more efficient. Fungi may even digest nutrients by releasing enzymes into the environment.
Explanation:
I have a strange feeling that this isn't the answer you were looking for.
C = dominant
c = recessive (cystic fibrosis)
CC, cc = homozygous (homo = same)
Cc = heterozygous (hetero = different)
Recessive traits are expressed only when two recessive alleles are present
If you get CC, you will not have cystic fibrosis. (<span>c </span>is the cystic fibrosis allele)
This person would be homozygous dominant and would not pass on the disease because they do not have any cystic fibrosis alleles.
If you get<span> Cc</span> you will not have cystic fibrosis b/c the<span> C</span> is dominant and overrides the cystic fibrosis allele c.
This person would be heterozygous and, though they do not have the disease, they would still have a chance of passing on the disease because they carry the cystic fibrosis allele.
If you get cc you will have cystic fibrosis b/c c is the cystic fibrosis allele and it is not being overridden by a dominant allele.
This person would be homozygous recessive.
Answer:
They have the same concentration.
Explanation:
Isotonic, by definition, means that the two solutions are of equal concentration
