Answer:
It contains only about an eighth of our sun's mass. Faint red Proxima Centauri is only 3,100 Kelvin (5,100 degrees F or 2,800 C) in contrast to 5,778 K for our sun. So Proxima is 500 times less bright than our sun.

Answer:
A neuron's nucleus is located in its CELL BODY
A nerve impulse moves toward a neuron's cell body along AXON
Explanation:
A neuron consists of three major parts: cell body, dendrite and the axon.
1) The cell body consists of the nucleus and cytoplasm
2) Dendrites are short cytoplasmic filaments which conduct impulses towards the cell body
3) Axon is made up of a single, long fibre which transmits impulses away from the cell body
I think the correct answer from the choices listed above is option A. When crossing-over takes place, chromosomes exchange corresponding segments of DNA. Corresponding genes on non-sister chromatids are exchanged at chiasmata. Hope this answers the question.
There will always be one stronger species that take over, which is what evolution has taught us.
I believe the answer would be D. <span>Only one will survive.
Have a good day!</span>
A temperate forest is likely
to have numerous flowers from flowering

facilitate pollination. The flowers contain nectar that attracted birds, bees and other
nectar-sucking animals. The nectar is produced by nectaries
in hollow
tube in the flowers. Therefore for birds to access
the nectar they require to have long slender beaks as an adaptaition.
