Binds structures, protects/supports, fills in spaces, transports materials, and makes red blood cells, stores energy, immunity, repairs tissue. Resist distortion, more flexible. <span>Together, our bones, muscles, and joints — along with tendons, ligaments, and cartilage — form our musculoskeletal system and enable us to do everyday physical activities.</span>

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.

What vitamin does the skin play a role in manufacture?

tatuchka [14]

The skin plays a role in the production of vitamin D because when dehydrocholesterol reaches the skin by means of the blood and is exposed to ultraviolet light from the sun, it changes to vitamin D in an inactive form.

For each region of the lac operon on the F' plasmid, I+ P+ Oc Z− Y+ , determine whether the region is wild type (that is, it pro

UNO [17]

Answer:

A,B and E

Explanation:

I+: I refers to the lac repressor, the + indicates that the repressor is functional

P+: P refers to the promoter region and the + indicates that the promoter is functional

Oc: O refers to the operator region, but the Oc indicates that the operator is constitutive ie. that it is always on/ can't be turned off.

Z-: Z refers to the LacZ gene which produces β-galactosidase. Z- indicates that this gene is non-functional

Y+: Y refers to the LacY gene which produces the permease protein. Y+ indicates that this gene is functional

So based on the breakdown above:

A is true because P+.

B is true because I+.

C is not true because the lac operon is an inducible system. The operator needs to be able to be repressed. In this case the operator is constitutive (always on) which is not the correct form.

D is not true because Z-, no β-galactosidase is produced.

E is true because Y+.

Only A, B and E apply.
