Answer:
Retinoblastoma is more common in people due to the mutation of RB gene in them.
Explanation:
Retinoblastoma is a disease that affects the eyes of an individual. It is more commonly eye cancer which occurs on the retina of the eye. Retinoblastoma mainly affects younger children.
When the RB gene is mutated or it is deleted already on any one of a homologous chromosomes, then only one hit rather that two which is needed to cause the development of retinoblastoma and hence the probability is of retinoblastoma to occur is higher in the individuals who have already inherited the RB deletion and also have a genetic predisposition for the retinoblastoma.
Answer:
The correct answer is option B, that is, an endoskeleton evolved to enclose the dorsal nerve cord, which develops from the notochord.
Explanation:
It has been discovered that the ancestors of the modern-day fish were vertebrate chordates. The vertebrate chordates are considered to have evolved from the invertebrate chordates that are identical to the present day tunicates. It has been found that in vertebrates the endoskeleton has evolved to encompass the dorsal nerve cord that has been developed from the notochord (a characteristic of invertebrates).
That would be false. The Ozone layer is what protects Earth from UV radiation. The Ozone is part of the Stratosphere.
Kinetic chain checkpoints represents the six anatomical locations of predictable movement patterns and is denoted as option B
<h3>
What is Kinetic chain checkpoints?</h3>
These are groups of body segments, connecting joints, etc which have a connection to the spine in the human body.
They work together to ensure body parts are easily moved and makes the detection of movement dysfunctions easier.
