Answer:
The development of sharper visual acuity.
Explanation:
At one week after birth, they can see red, orange, yellow and green. However, babies see red as the first primary color.
Many advances in vision development take place in months two and three. Infants develop sharper visual acuity during this period, and their eyes are beginning to move better as a team. A child should be following moving objects at this stage and starting to reach for things he sees.
Answer:
The possible arrangements of alleles on the F1 progeny's chromosomes will be AZ/Az or aZ/az
Explanation:
The genotype of F1 progeny is AaZz
The allele pair of gametes would contain one allele for characteristic represented by "A or a" and other allele for characteristic represented by Z or z"
Thus, total four allele pairs will be formed.
First allele pair would be - AZ
Second allele pair would be - Az
Third allele pair would be - aZ
Fourth allele pair would be - az
Hence, the possible arrangements of alleles on the F1 progeny's chromosomes will be AZ/Az or aZ/az
Answer:
all of these seems reasonable except the last one
If left untreated, excessiveerosion can lead to serious problems, such aswater sedimentation and ecosystem damage.Wind: Wind erodes the surface of a barren landmass in arid climates. Wind circulates and pushes particulates across wide bodies ofwater; a process known as deflation, which eventually leads toerosion.
