Answer:

IAi

Explanation:

The genotype for O blood is ii. So his mom must have given him an i allele. So he has at least one i allele.

But since his phenotype is A -- he expresses A -- there must be one IA allele. Otherwise, if he had both ii, he would be an O-type blood.

So his genotype must be IAi.

The hotter the star, the more light it gives off, the cooler the star the less light it gives off. Stars that follow this patter
Dafna1 [17]
(note: this answer is mostly from my star knowing bro who can't get online right now)

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

A. NEUTRON STARS
