<span>The correct answer is membrane. Just like the fence protects the yard so does a membrane protect the cell. It prevents things from getting in or out unless passageways are created. The things in the yard would be the mitochondria and other organelles, while the air in the yard and the ground where all things are found would be the cytoplasm. The membrane protects what's in just like a fence protects those in the yard.</span>
The dendrites receive incoming signals while axons propagate signals away from the neuron cell body. The myelin sheath surrounds and insulates the axon.
Answer:
B. He has no E alleles.
Explanation:
In order for the boy to have an attached earlobes phenotype, he must have no E alleles, because the E is dominant. So his genotype must be ee. If he has even just a single E allele (like Ee) he will have detached earlobes, because the dominant trait will mask the expression of the recessive trait.
Why not A or D: Heterozygous Ee (one of each allele) would result in detached earlobes.
Why not C: If he has no recessive alleles, EE, he would have detached earlobes.
D: Weather
Weather is <span>the state of the atmosphere in regards to heat, light, wind, rain, etc.</span>
