Answer:

Nitrogen cycle

Explanation:

Nitrogen fixation is the process by which atmospheric nitrogen is converted by either a natural or an industrial means to a form of nitrogen such as ammonia. In nature, most nitrogen is harvested from the atmosphere by microorganisms to form ammonia, nitrites, and nitrates that can be used by plants.

Assuming dragon genetics follows the same rules as fruit flies, what ratio of genotypes would you expect if the genes were not l
andrew11 [14]

Assuming dragon genetics follow the same rules as fruit flies, we would get the same possible genotype for all 16 offspring provided that the genes are not linked.

Considering dragon genetics, flame eyes (F) are dominant to blue eyes (f) and burbling (B) is dominant to whistling (b).

Now, a dihybrid cross between two homozygous blue-eyed, whistling dragons will yield 16 offspring all with the same possible genotype .i.e. homozygous blue-eyed, whistling type.

Morgan through experiments on fruit flies observed that when the two genes in a dihybrid cross were situated on the same chromosome, the proportion of parental gene combination were much higher than the non-parental type.

He attributed this due to the physical association or linkage of the two genes and coined the term 'linkage' to describe the physical association of genes on a chromosome. The term 'recombination' is to describe the generation of non-parental gene combination.

An echocardiogram reveals Charles, an ultramarathon runner, has an enlarged left ventricle. As this increase in ventricular size
astra-53 [7]

Answer:

The correct answer would be - physiological hypertrophy.

Explanation:

Physiological hypertrophy of is a condition of the heart that occurs in return of the normal growth an individual such as an athlete like Charles who is a marathon runner in this case.

Left ventricle hypertrophy is a common type of hypertrophy that occurs in this condition in which the left ventricle of the heart increase in size temporary which arises in response to the exercise and function is done by muscles.

thus, the correct answer is - physiological hypertrophy.

Neurotransmitters transmit ____________ between ____________ , from neurons to glands, from neurons to organs, and from neurons
astraxan [27]

Answer:

1. Nerve impulse

2. Neurons

Explanation:

Neurotransmitters are compounds with low molecular weight. They are secreted by axon terminals of the neurons. The released neurotransmitters then bind to the receptors located on next neuron or on the surface of muscle cell.

The function of neurotransmitters is to carry the nerve impulse from presynaptic neuron to the postsynaptic neuron or from neurons to the effector organs such as muscles and glands.  

For example, neurotransmitters are released into the synaptic cleft to transmit the nerve impulse between neurons.
