Radio telescope picks up the radio spectrum of electromagnetic waves from celestial bodies (just like telescopes like the Hubble pick up visible light – only that radio waves are invisible to our eyes). They are therefore used to detect objects in space that produces radio waves. Examples are quasars and pulsars. Radio telescopes also enable astronomers to be whats beyond gas and dust in space that blocks out most of the visible light spectrum.

Answer:

Radio waves from space are sensed by a giant parabolic reflector which concentrates them toward the top of a focusing antenna. A radio receptor converts the radio waves into electrical signals which are amplified and then transmitted to the center of the parabola. They are then recorded and analyzed in the laboratory so that scientists can obtain a radio image of the source observed. The parabolic antenna can usually be oriented to detect radio waves from all directions of space.

In the female in the spring the become larger with

Finger [1]

The female frog's reproductive system is consist of a pair of ovaries and a pair of oviducts. The ovaries are attached to the kidneys. The kidneys carry countless ova which are released to outside through the oviducts. In the breeding season, the male and the female frogs enter into a temporary union called amplexus. The male holds the female, presses her trunk and thereby forces the female to release the eggs, the male frog then releases the sperms immediately to bring about exterior fertilization.

agonists generally _______ activity at the synapse while antagonists generally ______ activity at the synapse.

ki77a [65]

Agonists activate the receptor thereby increasing activity at the synapse while antagonists generally prevent agonists from activating the receptors thereby decreasing activity at the synapse.

An agonist is the component that has the ability to increase the activity carried out by another substance.

The agonists work from their faculty of coupling to a cell-type receptor, in this way, they manage to generate a certain action in the cell.

The antagonists are the compounds that cause the opposite when they bind to the receptor, they cause a blockade by decreasing the activation of a synaptic receptor.

Therefore, we can conclude that agonists are compounds capable of increasing the action of synapse and blockers (antagonists) decrease activity at the synapse.
