Question

which telescope uses lenses to collect and focus light and form an image? * 1 poin
○ adaptive
○ radio
○ reflecting
● refracting

what is the first stage of a stars evolution * 1 poin
● aquarius
○ white dwarf
○ red dwarf
○ protostar

Explanation:

First Question (Telescope Type)
Brief Explanations

A refracting telescope uses lenses to gather and focus light to form an image. Adaptive telescopes adjust for atmospheric distortion, radio telescopes detect radio waves, and reflecting telescopes use mirrors. So the correct option is the one with "refracting".

Brief Explanations

The first stage of a star's evolution is a protostar (when gas and dust collapse under gravity). Aquarius is a constellation, white dwarf is a later stage, red dwarf is a type of star but not the first stage. So the correct option is the one with "protostar".

Answer:

D. refracting (assuming options are labeled A - D as adaptive, radio, reflecting, refracting respectively)

Second Question (Star Evolution Stage)
