In birds, males have two copies of the Z chromosome (ZZ) and females have a Z chromosome and a W chromosome (ZW). Females transm
it a Z chromosome to their sons and a W chromosome to their daughters, while males transmit a Z chromosome to both their sons and their daughters. Based on this information, which statement is true? A) A mutant phenotype due to a recessive Z-linked allele will be more common in males than in females. B) Males are hemizygous for Z-linked genes. C) Females who receive one Z-linked mutation are heterozygous carriers. D) A recessive Z-linked trait can skip a generation if it passes through a carrier (phenotypically normal) son. E) All of the above
Common insect adaptations include an exoskeleton (outer skeleton), camouflage, wings, the ability to have lots of babies, and adapted legs and mouthparts
The sun has less gravitational pull on Neptune because it is farther away. Gravity is the force by which a planet or other body draws objects towards its center.
Gravity keeps all the planets in its position and allows it to move in its orbit.
The force of gravity is inversely proportional to the distance between two objects.
So when the distance increases, the force weakens. Since Neptune approximately 4.8 billion kilometers away from the sun, its gravitational force is very less.
