Question 1: Some cells produce and secrete high levels of digestive proteins. Which organelles would you expect to be abundant in those cells, and why? Question 2: Explain how active transport helps a nerve cell maintain its resting potential. Question 3: The Atlantic cod is a common fish of the Atlantic Ocean that must drink seawater to meet its water needs. Explain how active transport helps the Atlantic cod maintain homeostasis with regard to the balance of sodium and chlorine ions, which are abundant in seawater. ( Will Mark Brainliest). No Nonsense Answers.
Answer:
q1 : ribosomes because they are responsible for protein synthesis
q2 : by transporting potassium ions into the cell and sodium ions out of the cell maintaining a concentration gradient
q3 : seawater contains a high concentration of sodium and chlorine ions that the Atlantic cod gets rid of by actively transporting them out of its body

Which of the following best describes sickle-cell anemia?
O Caused by environmental factors that an individual was exposed to during pregnancy.
O A hereditary genetic mutation that causes a resistance to malaria.
O An inherited disorder that increases the risk of contracting malaria from mosquitos.
O A genetic mutation that is inherited from a dominant allele of one parent.
Answer: The answer should be B "O A hereditary genetic mutation that causes a resistance to malaria."
Explanation:
I do FLVS also you can find this out in your lesson 3.04 on page 5.
It says, "Sickle-cell disease is a genetic disorder that gives red blood cells a crescent shape instead of the typical disk shape. Sickle cells are stiff and sticky. They tend to block blood flow in the blood vessels of the limbs and organs. Blocked blood flow can cause pain, serious infections, and organ damage. This genetic disease is recessive, meaning the allele must be inherited from both parents to be expressed in a person’s phenotype. It is caused by a mutation in the gene that produces hemoglobin, the blood’s principle oxygen-carrying protein. Sickle-cell disease occurs more commonly in people and descendants from tropical and subtropical regions where malaria is common. Scientists have discovered that individuals with just one allele for sickle-cell disease are not only healthy, but they actually have a high resistance for the parasite that causes malaria. This resistance gives the carriers of one sickle-cell allele a great advantage over malaria, which claims more than a million lives each year, and explains why the allele for this dangerous genetic disease survives to be passed down to future generations."
Have a great day hope this helped!!!

The sickle cell gene is inherited and results in sickle cell disease. You cannot catch HPV from an infected person because it is not brought on by whatever the parents did either before or during the pregnancy. Thus, option B is correct.
What are the characteristics of sickle-cell anemia?Red blood cells are typically disc-shaped and sufficiently flexible to pass readily through blood arteries.
Red blood cells with sickle cell disease have a crescent or “sickle” shape. Because sickle cells impede blood flow to particular organs, sickle cell disease complications can develop.
The severe side effects include stroke, acute chest syndrome, organ damage, various disabilities, and even early death. Acute chest syndrome lowers the blood's oxygen content.
Therefore, A hereditary genetic mutation that causes a resistance to malaria.

The cell membrane of an animal cell was damaged, preventing the cell from performing one of its functions. Which cell function would be lost, and how would this loss affect the cell?
Answer:
ok so
Explanation:
If the cell membrane of an animal cell is damaged, it would lose the ability to take in nutrients and excrete wastes. This would hinder the cell's capacity to create necessary materials and maintain proper functioning. Thus, the correct option is (b).
The correct response is option (b). The transport of chemicals into and out of the cell is regulated by the cell membrane, which acts as a selectively permeable barrier. Essential cell processes like food intake and waste elimination would be impeded if the membrane were to get disrupted.
This would impede the cell's capacity to produce required components through nutrient-dependent processes like metabolism. There would be a significant negative impact on the cell's general health and function, which could result in cellular malfunction, slowed growth, and ultimately cellular death.

What happens when the thin filament in a muscle fiber slides over the thick filaments?
Answer:
As the thin filaments slide inward, structures called Z-discs come toward each other and the sarcomere shortens but the lengths of thick and thin filaments do not change. The sliding of the filaments and shortening of the sarcomere cause shortening of the whole muscle fiber and ultimately the entire muscle.
Answer:
Sliding of the filaments and shortening
Explanation:
As the thin filaments slide inward, structures called Z-discs come toward each other and the sarcomere shortens but the lengths of thick and thin filaments do not change. The sliding of the filaments and shortening of the sarcomere cause shortening of the whole muscle fiber and ultimately the entire muscle.

The coordinated action of two types of myofilaments, actin and myosin, results in muscle contraction. The muscles contract as actin filaments slide over myosin filaments. When the muscle is in a relaxed state, the myosin heads are ready to bind with the actin filament. However, they are not able to bind due to
a.
the absence of ATP
b.
a high concentration of Ca++ ions
c.
blockage of the attachment site
d.
alcoholic fermentation
Answer:
I think due to absence of ATP but I'm not sure.. Actin and myosin return to their unbound state causing the muscle to relax. Alternatively relaxation (failure) will also occur when ATP is no longer available.
Myosin heads are ready to bind with the actin filament they are not able to bind due to the absence of ATP.
How two myofilaments involved in muscle contraction?Muscle contraction results from an intercommunication between the actin and myosin filaments which generate movement relative to one another.
What happens to the actin and myosin filaments when a muscle contracts?Myosin movement appear to be a kind of molecular hop. The myosin reaches forward, binds to actin, contracts, releases actin, and then reaches forward again to bind actin in a new cycle.
What happens to actin and myosin during muscle relaxation?Relaxation occurs when nerve stimulation stops. Calcium gets moved back into the sarcoplasmic reticulum shattering the link between actin and myosin. Actin and myosin then return to their unbound state causing the muscle to relax.
