The molecules of air inside of an inflated balloon are very far apart and moving rapidly. They collide with other molecules and with the inside surface of the balloon. Collisions between gas molecules are perfectly elastic.
Answer:
A. 0
Explanation:
Both red-green color blindness and and shape of hairline are independently assorting genes.
Red-green color blindness is X-linked recessive while hairline shape is autosomal dominant.
The man who has widow's peak had a father with straight hairline. This means that the man is heterozygous for the trait.
Assuming hairline shape is represented by S. A heterozygous widow's peak man will have a genotype of Ss. A straight hairline woman will have a genotype of ss.
Assuming the allele for colour blindness is c. A normal vision man will have the genotype 
while a color blind woman will have the genotype 
.

<em>The man does not have the color blind allele and a daughter will need two color blind alleles (one from the father and the other from the mother) in order to show the trait.</em>
<em>This means that the probability of the couple producing a color blind daughter is 0. Hence, the chance that any daughter the couple has will be color blind with a straight hairline is also 0.</em>
The correct option is A.
Prophase I : Condensation of chromosomes and nuclear envelop breakdowns.
Metaphase I : Pairing of homologous chromosomes and chromosomes line on metaphase plate.
Anaphase I : Homologous pair chromosomes separate and move opposite sides.
Telophase I : Chromosomes reach spindle poles.
Cytokinesis : Division of cytoplasm, division of cell takes place.
Answer:
chemicals that cross the synaptic gap and bind to receptors on another neuron
found only in the central nervous system (the brain and spinal cord)
Explanation:
Neurotransmitters are defined as the chemicals that is transported from a nerve cell across the synaptic gap to the receptor of another neuron or a target cell such as a gland cell or a muscle cell.
Neurotransmitters are generated in the central nervous system (the brain and spinal cord) and are stored in synaptic vesicles.
"Hence, the correct answer is:
chemicals that cross the synaptic gap and bind to receptors on another neuron
found only in the central nervous system (the brain and spinal cord)".
