Mutations in the genes for clotting factor VIII and IX cause hemophilia A and B, respectively. A woman may be heterozygous for m

utations in both genes, with a mutated factor VIII allele on one X chromosome, and a mutated factor IX allele on the other. All of her sons should have either hemophilia A or B. However, on rare occasions, one of these women gives birth to a son who does not have hemophilia, and his one X chromosome does not have either mutated allele. Explain.

Hello. This question is incomplete. You forgot to attach the image that completes the question.

The image is attached below:

Answer:

A- Sensory Neuron

B- Spinal cord

C- Effector neuron

D - Brain

Explanation:

  1. Sensory neuron: Its main function is to allow the reception of stimuli that are transformed into nervous impulses and electrical signals, capable of realizing sensations, such as a peliscão, for example. These impulses are transmitted to the spinal cord.
  2. Spinal cord: The main function is to support the body in an upright and vertical position. It also has the function of transmitting electrical signals and nerve impulses between some parts of the body and the brain.
  3. Effector neuron: Its main function is to receive muscle stimuli capable of creating muscle contractions. These neurons are located in the spinal cord.
  4. Brain: the processing center receives all the stimuli sent by the bone marrow. Its main function, in this case, is to produce bodily responses to the stimuli it has received, producing muscle movement.

2. they don't fit in our mouths so are a trait from when we had larger jaws

3. bones of your lower jaw, middle ear and voice box (they aren't actually gills fyi, they just look like them)

4. likely yes as their bones were hollow but likely only able to fly short distances, the thought was that they couldn't do their size and weight but with hollow bones they were able to like a quail would

5. no because they could be sister taxa, you would have a hard time proving exactly that this new fossil is the common ancestor that birds came from to replace the old hypothesis (guess) of which one did.
