Many species have embryos that look similar to one another and develop similar structures. Refer to the picture above. During th

e first stage of embryonic development for each species, what type of evolution could you conclude about the relatedness of the organisms? A) Divergent evolution because all of the species have similar structures during the first stage of development. B) Convergent evolution because a,l of the species have similar structures during the first stage of development. C) Divergent evolution because the species are fundamentally different even at the first stage of embryonic development. D) Convergent evolution because the species are fundamentally different even at the first stage of embryonic development.

Cerrena [4.2K]

Answer:

1. The parents genotypes could have been BO and AO

2. wire-hair

Explanation:

There are four possible blood types which are type A, B, AB, O. blood group is the classification of blood based on the presence or the absence of inherited antigenic substances on the surface of the red blood cells. They have hereditary basis and also rely on a series of alternative genes sometimes used in solving dispute of parental heritage. With the four possible blood groups, there are six possible genotypes and these are:

Blood type               possible genotypes

Type A                         AA, AO

Type B                         BB, BO

Type AB                           AB

Type O                              OO

Thus, for parents with blood type B and A to give birth to a child with blood type O, it means their genotype could have been both BO and AO  for them to be able to produce a child with OO. a cross between these two could give rise to OO.

Question 2

Wire hair is dominant (S) to smooth (s), thus wire hair could be in the homozygous (SS) and heterozygous form (Ss) and the smooth hair can only be expressed in the homozygous recessive form (ss).

thus, in a cross between homozygous wire haired and smooth haired, we will have:

homozygous wire haired            homozygous smooth haired

P gen              SS                x               ss

F1 gen.                                Ss

phenotype:                     wire haired

seraphim [82]

Answer:

east to west

Explanation:

The stars and moon are the celestial bodies which are located at distant.

The distance of stars vary but moon and sun remain same. As our Earth rotates at its own axis, other celestial bdies seem to move.

As Earth spins from west to east, the stars and moon seems to move from east to west direction at night and same with Sun, it also seem to move from east to west.

Hence, the correct option is east to west.
