The sickle-cell allele produces a serious blood disease in homozygous recessive individuals. why doesn't natural selection elimi
icang [17]

No, the sickle-cell anemia allele won't be eliminated by natural selection.

Sickle-cell anemia trait is controlled by a single gene and the allele (S) for sickle-cell anemia is a harmful autosomal recessive.

It is caused by a mutation in the normal allele (A) for hemoglobin (a protein on red blood cells).

Heterozygotes (AS) with the sickle-cell allele are resistant to malaria, a deadly tropical disease. It is common in many African populations.

In these areas, (S) carriers have been naturally selected, because their red blood cells, containing some abnormal hemoglobin, tend to be in sickle shape when they are infected by the malarial parasite.

Therefore, they are more likely to survive and reproduce. This keeps the S allele in the gene pool.

A neuron transmits information by the secretion of hormones. True or False
grandymaker [24]

Answer:

The given statement is false.

A neuron is the basic structural and functional unit of the nervous system. It helps in transmitting information from one neuron to another neuron, gland, or muscle cell.

The conduction of nerve impulse is electrochemical in nature. It transmits the impulse electrically through the axon the nerve cells and chemically through synapses (gap between two nerves cells).

The axon terminals of pre-synaptic nerve cell release chemical messengers (also called neurotransmitters) in the synaptic cleft. These messengers then bind to the receptors present on the post-synaptic nerve cell and regenerate the nerve impulse.

Products enter a reaction and reactants come out of a reaction true or false?
hjlf

Answer:

\boxed {\boxed {\sf False }}

Explanation:

In a chemical reaction, the <u>produc</u>ts are <u>produc</u>ed. The <em>react</em>ants are the substances that <em>react.</em>

<em />

In a chemical reaction equation (with the arrow pointing right) the reactants are on the left and the products on the right.

  • reactants \rightarrow products

The reactants enter and the products come out.

So, the statement given - products enter a reaction and reactants come out - is false and it is actually the other way around.
