Answer:
Either the Chloroplasts or the cell wall
Explanation:
Answer:
Any process that involves active transport most often involves the expenditure of energy in the form of ATP hydrolysis.
Explanation:
Active transport in cells is a form of transport which involves the transport of solute molecules across a membrane against a concentration gradient using energy provided from some chemical reaction occuring in the cell.
Active transport is an endergonic (energy-requiring) process and therefore, must proceed only when coupled to an exergonic (energy-releasing) process such as the breakdown of ATP, an oxidation reaction, absorption of sunlight, etc.
In many instances in cell, such as the Na/K pump, ATP hydrolysis is the the common exergonic reaction to which active transport is coupled to.
Answer:
D. Fibrocartilage
Explanation:
In order to understand the question, we need to review the structure of intervertebral discs.
Intervertebral discs consist of two parts:
It forms the central part of the intervertebral disc and consists of mucoid substance.
It is composed of encircling layers of fibrocartilage and fibrous tissue surrounding the nucleus pulposus
<u>SLIPPED DISC:</u>
It is characterized by the protrusion of nucleus pulposus through the annulus fibrosus accompanied by the compression of spinal nerves.
Patient may present with loss of sensory sensations or pain or both.
<u>CORRECT ANSWER:</u>
From the above review, the correct answer is <u>D. fibrocartilage</u> as it forms the annulus fibrosus.
Answer:
An energy transformation is the change of energy from one form to another. Energy transformations occur everywhere every second of the day. There are many different forms of energy such as electrical, thermal, nuclear, mechanical, electromagnetic, sound, and chemical.
Chloroplasts contain chlorophyll which is what makes plants green. Onions are not green because they do not contain chloroplasts. The reason they do not have chloroplasts is because in the chloroplast, photosynthesis takes place. A key player in the process of photosynthesis is the sun. The onion itself grows underground which means while they grow they do not come into contact with the sun so chloroplasts in an onion is pointless since they can’t undergo photosynthesis. Hope I helped!
