How did scientists determine SM0313 is the oldest star ever discovered?
levacccp [35]

i think it has to do with how old it looks, because a star starts off as a baby little star, a different color and size. its also in a nursery with a lot of other stars, which is called a nebula. as the stars grow older and larger, they change color and drift apart. the scientists must've seen that the star has a totally different color from the baby ones, way brighter and much larger, also seeing that stars grow apart, it has not really many stars living around it for miles and miles. they must've guessed that it was probably really old.

Answer:

The correct answer is option (d)-"All of these are found in the fossil record and have been used by scientists to understand human evolution".

Explanation:

There is plenty of evidence that supports the proposal of how humans has evolved during past times. The fossil records that scientists has used understand human evolutionary patterns include the following. Ardipithecus ramidus bones  that revealed advances in upright walking, even tough they had a small brain that measured between 300 and 350 cm3.

Please help!!!! very confused pt 2
Schach [20]

Answer:

If the genotype of the parents are <em>Iᵃi </em>and <em>I</em>ᵇ<em>i, </em>then four type of offspring will be produced.The genotype of the offspring are, <em>IᵃIᵇ, Iᵃi,Iᵇi, </em>and <em>ii.</em>

Explanation:

<em>IᵃIᵇ = </em>As the alleles are co-dominant in nature, so both type of alleles are expressed. The blood group will be AB. So, both A and B type of antigen will be found in plasma membrane of RBC.

<em>Iᵃi= </em>In this type of genotype only A type of antigen will be expressed in the membrane of RBC. The blood group will be A type.

<em>Iᵇi= </em>In this type of genotype only B type of antigen will be expressed in the membrane of RBC. The blood group will be B type.

<em>ii= </em>This is a recessive type of genotype. So, no antigen will be found on the membrane of the RBC. And the blood group will be O type.

The offspring's ratio will be 1:1:1:1.
