B. Transform boundaries are when the land rubs back and forth against each other causing earthquakes
Answer:
Processing and packaging of cellular materials prior to export
Explanation:
Our cells contain many different organelles. Every organelle has its own function, just like every organ in our bodies.
The Golgi apparatus is one of these organelles. It can be found in most eukaryotic cells. Its purpose is to transport, modify, and package proteins and lipids before they're delivered to other parts of the body. This is the function the organelle with smooth-sided channels Megan is observing would need to perform in order to be identified as the Golgi apparatus.
Spondylosis is a term for age-related wear and tear of the spinal disks.
I think the thalamus is the gateway to the cerebral cortex. Thalamus is a small structure within the brain located just above the brain stem between the cerebral cortex and the mid brain and has extensive nerve connections to both. Its main function is to relay motor and sensory signals to the cerebral cortex. A sensory impulse travels from the body surface towards the thalamus, which receives it as a sensation, which is then passed onto the cerebral cortex for interpretation as touch, pain or temperature.
Answer:
Threonine has two chiral centers.
The correct options are c. carbon b and d. carbon c
Explanation:
Chiral centers are those that have four different groups of atoms bonded to it. Carbon a has three atoms of hydrogen attached to it so it can't be a chiral carbon. It isn't the carboxyl carbon either since it is double bonded to oxygen. And the amino nitrogen does not qualify anyway because it is bonded to three different groups of atoms, not four.
