Which of the following pairs is correctly matched? A) lumbar vertebrae; bifid spinous processes B) thoracic vertebrae; triangula
r vertebral foramen C) lumbar vertebrae; short, flat spinous processes D) thoracic vertebrae; transverse foramen E) cervical vertebrae; rib facets
1 answer:
Answer:
C) lumbar vertebrae; short, flat spinous processes
Explanation:
The Lumbar Vertebrae are bigger and stronger than vertebral bodies in certain positions.
The vertebral bodies and disks bares majority of the body weight of the body. The lamina, facets and spinous process are basic components of the posterior materials that assist in guiding the movement of the vertebrae and as a coverage or protective shelter for the spinal cord.
The spinous process are SHORT and STURDY (FLAT) in the Lumbar Vertebrae. Hence, this explain why it is often referred to as "Hatchet-Shaped".
The attached image as red dots meant to point to the spinous process in the Lumbar Vertebrae.

Answer:
False, they can have recessive phenotype
Explanation:
A phenotype is a viable characteristic an individual presents as a consequence of the interaction between its environment and its genotype.
This doesn’t necessarily means that the individual’s aleles are both dominant (homozygotes), they could have one dominant and one recessive gen (heterozygotes), meaning that, if the another parent is homozygote with both recessive aleles the offspring could heritage homozygote recessive aleles that will result in a recessive phenotype.
You can observe in the image I added a punnet square that exemplifies the scenario. You can see that the offspring has 1/2 probability to have recessive phenotype.
I hope you find this information useful and interesting! Good luck!
