Answer:
"Variations that decrease reproductive success are more likely to be passed on" is the one statement among the choices given in the question that would least likely be used to describe variation. The correct option among all the options that are given in the question is the second option or option "B".
Explanation:
Answer:
Reproduction is the biological process by which new individual organisms – "offspring" – are produced from their "parents".
Explanation:
The obvious answer is a bc it does not use and toxic fuels
Answer: The correct option is c. Segmentation evolved more than once in different branches of the cladogram.
Phylogenetic studies help to identify and understand evolutionary relationship between different life forms. It uses a diagram called as Cladogram to represent the branching of the evolutionary relationships. In cladogram studies each branching point tells a fundamental character of the evolutionary significance. Cladogenesis separates the gene pool by splitting into two or more than two separate pools each of which gives rise to one or more new species. Segmentation implies repeated parts and many animals consist of such repeated parts. Therefore, segmentation appears more than once in different cladogram branches.

The temperature of the star only has to do with the color of the star, not how much light it gives off (according to the HR-diagram (google it)). The amount of light it gives off is determined by its surface area, the more surface are it has, the more light it gives off.
lets talk about the options
A. neutron stars: extremely dense (heavy) stars, that have blown up and only have their extremely dense core left. and this is wrong since it does not do thermonuclear fusion and therefor does not emmit its own light except when it swallows something and gets brighter and hotter as a result
B. Black holes: neutron stars that have a mass greater than 3 solar masses. these 'stars' have so much gravity, that do not let light to escape, so it does not have much tempurature and all light is sucked in and not released in a visible form
C. Giants:either middle sized stars that are entering their last stages of their lives, or huge main sequence stars. They behave the same way as main sequence stars in that the bigger the surface area of the star, the more light it gives off, and the tempurature determines the color not the amount of light
D. Main sequence stars: same as giants
we can eliminate main sequence stars and giants because they are the same but different sizes.
we can eliminate black holes because they don't let light to escape
therefor the asnwer is A. neutron stars
ANSWER
A. NEUTRON STARS
