Answer:
A. damaged her peripheral nervous system because the information regarding taste cannot be transmitted back to her brain.
Explanation:
The nervous system is an important system of our body and is directly related to our survival. This system is linked to the coordination of the organism's various activities and is also responsible for allowing the interpretation of the environment around us.
The nervous system is an important system of our body and allows us to have emotions, to remember an important moment in our lives, to interpret smells, tastes and images, to make movements and even to stay alive through the automatic breathing and heartbeat.
Taste, that is, the sense of taste is directly linked to the peripheral nervous system. For this reason, if Stacey has lost her sense of taste, we can conclude that she has damaged her peripheral nervous system because taste information cannot be transmitted back to her brain.
The answer is skin. The skin is also the largest organ in the body and has the most contact with the outside environment. It is estimated that there are approximately 205 identified genera of bacteria alone on the skin. This normal flora of the skin play significant roles in the body such as augmenting immunity.
Answer:
This question lacks options, the options are:
A. Only recessive alleles are inherited from homozygous parents.
B. Dominant alleles grow weaker as they are passed from parents to offspring.
C. Only the parent with a dominant allele can pass that allele to offspring in sexual reproduction.
D. A heterozygous parent has an equal chance of passing either the dominant allele or the recessive allele to offspring.
The answer is D
Explanation:
This question involves a single gene coding for hair length in dogs. The allele for short hair (S) is dominant over the allele for long hair (s). This means that allele 'S' will always mask the phenotypic expression of allele 's' in a heterozygous state.
According to the question, two heterozygous dogs (Ss) were crossed to produce 6 shortt-haired offsprings and 2 long-haired offsprings. An heterozygous organism is that which contains two different alleles for a particular gene i.e. a combination of dominant and recessive alleles.
Based on this, during meiosis or gamete formation, an heterozygous dog (Ss) will produce gametes with the short hair allele (S) and long hair allele (s) in equal proportion i.e. 50-50. When the two gametes containing the recessive alleles (s) produced by each heterozygous parent fuses, an offspring with a recessive phenotype (long hair, ss) is produced.
Hence, a long-hair
phenotype can appear in the offspring of two short-haired dogs because a heterozygous parent has equal chance of passing either the dominant or recessive allele to the offspring.
Answer:
Dendrites, cell body, axon hillock, axon, synaptic terminals, biceps brachii.
Explanation:
Neurons are the structural and functional unit of the nervous system. The neurons helps in the transmission of nerve impulse in the body. Two main types of neuron are somatic neuron and motor neuron.
The signal is first reach to dendrites. From the dendrites, the signal transmit to the cell body and then to the axon hillock. The signal then transmits to the axon. At the end of neuron the message is transmitted to the synaptic terminal. The nerve impulse finally reaches to the biceps brachii and results in the flexion of the arm at the elbow.
