Answer:

They had a large brain size of 700 to 1,250 cubic centimeters and large brow ridges with a nuchal torus at the back of the skull.

Explanation:

<em>Homo erectus</em> was one of the species of the homo genus which were considered the first species to have the human-like the feature that is they can stand upright on two legs and were therefore referred to as the upright man.

They showed many evolutionary advances over their ancestors called Homo Australopithecus as they showed encephalization. Encephalization refers to the increase in the size of the brain due to more neuronal complexity and neurogenesis and they possessed about 750 to 1250 cc brain size.

They showed torus at the back of the muscle which can hold the muscle of the neck and also showed the large brow ridges in the front of the skull.

Thus, the selected option is the correct answer.

What are the advantages of being a respiratory parasite (the tongue worms) over one in the digestive system (if any)?
Nata [24]

Answer:

Explanation:

The parasites living at the respiratory system or tongue worms will hide under the soft tissues of the oral cavity, beneath the tongue and even beneath the throat or esophagus. These worms remain undetected during diagnosis. These worms are not subjected to the treatment of acids which worms in the digestive system are exposed to. Thus these worm parasites in the respiratory system or tongue survive comparatively for long as compared to the worms in the digestive system.

An action potential triggers the release of synaptic vesicles into the synaptic cleft by _____ channels, allowing _____ ions to
noname [10]

Answer:

1. opening Voltage gated channels

2. Calcium

Explanation:

The signals are transmitted in the neurons in the form of electrical signals and which are transformed into the chemical signals at the synaptic cleft.

The electrical signal is transformed into a chemical signal when the electrical impulse reaches the terminal of the axon and opens the calcium voltage channels. The calcium which is present in a higher amount than inside enter into the terminal and allows fusion of the synaptic vesicle carrying neurotransmitter and the neurotransmitter is released into the synapse.

The neurotransmitter then binds the receptors and initiates the electrical impulse in the postsynaptic neuron.

Thus, opening Voltage gated channels and Calcium is the correct answer.
