B. answer is correct. HIV that causes AIDS has RNA instead of DNA.

HIV is actually a retro-virus.

Acquired immunodeficiency syndrome (AIDS) is a chronic, potentially life-threatening condition caused by the human immunodeficiency virus (HIV). By damaging your immune system, HIV interferes with your body's ability to fight the organisms that cause disease. The human immunodeficiency virus (HIV) is a lenti-virus (a subgroup of retrovirus) that causes HIV infection and over time acquired immunodeficiency syndrome (AIDS).

Mkey [24]

The two ways the endocrine system and the nervous system are different in communication, is that the nervous system responds rapidly to short-term changes in the body by sending electrical impulses. And with the endocrine system, it takes longer, so it's a long-term effect until it notices any changes and when it does, it sends chemical messengers known as hormones into the body.

Now, how they are similar, is because both the nervous and endocrine systems work together to maintain homeostasis.

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.
