Answer:
1. Embedded in the plasma membrane
2. There is no diagram attached but the question can be answered based on general knowledge. The answer is Golgi apparatus/body.
Explanation:
1. Cholesterol is fat molecule produced in the Smooth Endoplasmic reticulum of animal cells. It is then transported to the plasma membrane, where it plays a vital role in the functionality of the plasma membrane. Hence, embedded in the plasma membrane of an animal cell is CHOLESTEROL, in addition to phospholipids.
2. The Golgi apparatus is an organelle in eukaryotic cells that functions in the modification and packaging of protein and lipid molecules produced by the RER and SER respectively.
Explanation:
-acid-base homeostasis
The cells within the brain or CNS ensure that more oxygen is taken into the lungs at a faster rate while carbon dioxide is removed; this aids in gaseous exchange and maintaining the pH of the blood- oxygen concentrations are kept high within the blood stream as blood circulates through the body.
Blood pH levels are typically within 7.35 --7.45. it is regulated by coordinated activity controlled by the brain, and carried out by the kidneys and lungs; along with red blood cells.
Further Explanation:
During homeostasis the body maintains a constant internal balance in pH, temperature, blood pressure etc. Cells in a multicellular organism become specialized for particular tasks and communicate with one another in order to maintain homeostasis.
Within the human body these are known as hormone cascades, where several complex steps occur- the tissues signal to one another with the use of hormones released by the endocrine system. The regulation (increase and decrease) of these secretions is achieved by feedback loops (positive and negative), where the release of certain substances during a cascade in turn halts the secretion of hormones at earlier stages.
The peripheral nervous system is divided into the somatic nervous system responsible for carrying out sensory and motor information between the peripheral nervous system- including sensory organs like the eyes; and central nervous system; and the autonomic nervous system (ANS) which regulates involuntary bodily functions like heartbeat, breathing and blood flow. The ANS is mainly acts unconsciously and affects smooth muscle and internal organs. It is related to homeostasis- where the body maintains a constant internal balance in pH, temperature, blood pressure etc.

From my understanding, #1 a) the large rectangle represents the heart. For b) the arrows in the model represent the direction of blood flow c) No, the % of oxygen does not stay constant throughout. I’m a biology major. If you need more help on this, post another question and message me the link. :)
