Which of the following is a way atp is used in cellular processes?
select all that apply
( I will CASHAPP you AND MARK BRAINLIEST if correct)
a. Oxygen production
b. Biosynthesis
c. Polyatomic ions
d. Muscle contraction
e. Detoxification
Answer:
The ways in which ATP is used in the cellular process are biosynthesis, muscle contraction and detoxification.
Explanation:
Adenosine triphosphate or ATP is a molecule that acts as an energy carrier, necessary for organic functions. Metabolic functions, molecule synthesis and body movement depend on the energy provided by ATP.
ATP has three phosphate groups in its molecule, united by a high-energy bond. When ATP is hydrolyzed, losing one phosphate, it becomes ADP and releases the energy contained in the bond that has been broken. This energy is used in processes such as biosynthesis or the contraction of muscle fibers.
Other processes in which ATP participates are active transmembrane transport —including the elimination of waste and toxins or detoxification—and DNA replication.
Regarding the other options
ATP is not linked to the production of oxygen, it has a polyatomic ion —phosphate— but it does not produce it.
A semipermeable tube containing 4% Cacı, 9% sucrose, and 10% ovalbumin is suspended in. a solution with the following composition: 10% CaCl2, 10% sucrose, and 40% ovalbumin. Assume
that the tube is permeable to all substances except ovalbumin, which is a large protein.
Use the following answer choices to state the movement of each solution:
(A) a net movement into the tube
(B) a net movement out of the tube
(C) no net movement.
A. Sucrose:
B. Ovalbumin:
C. Water:
D. Caci:
Answer:
Sucrose, CaCl2 = A
Water = B
Protein = C
Explanation:
Why we have a net movement out of the tube?
Because the osmotic pressure is higher out the tube.
That is due because of the greater presence of osmotically actice compounds.
Take a look:
Tube:
4% of CaCl2 > ([tex]Ca^+ + 2Cl^-[/tex])x 0,04
9% of Sucrose > (Sucrose)x 0,09 - Sucrose does not dissociate or ionize
10% of Protein > Does not matter it quantity, because she it's not a osmotic compound.
Solution:
10% of CaCl2 > ([tex]Ca^+ + 2Cl^-[/tex]) x 0,1
10% of Sucrose > (Sucrose) x 0,1
As both CaCl2 and Sucrose are in a higher concentration, we can understand that the osmotic pressure is greater in the Solution side, making the solution of the tube to migrate to her.
But maybe talk does not help. In the annex you can see a drawing of a possibility for this situation.
______
EDIT: I just saw that your question wasn't asking exatcly what I was trying to solve.
But anyway, by the same motives I already said, the answers are:
Sucrose and CaCl2 are going from the down tube - I know it does not sound possible, but imagine that they are really close ore even that they are side to side in the ground -, to the upper tube. That happens because of the EF that I said.
In the other side, water are leaving the uper tube, to equilibrate the concentration of compouns in both systems.
The protein can't move toward any tube, because as the question said, it is far bigger than the spots in the semipermeable membrane.
Also, it doest not has sufficiently interaction trough the other compounds.
Final answer:
Sucrose, CaCl2 = A
Water = B
Protein = C

Jake has become very anxious ever since he started taking harder classes in his major.
The university's counselor diagnosed him with an anxiety disorder. Compare and contrast how the behavioral, humanistic, and cognitive approaches would view the origins and treatment of Jake's anxiety. Then, describe how psychologists view each of
the three approaches today."
The behavioral, humanistic, and cognitive approaches provide different perspectives on the origins and treatment of Jake's anxiety.
The behavioral approach would view Jake's anxiety as a learned response that has been reinforced over time. They might suggest that Jake's anxiety is a result of negative experiences or associations with his academic performance, leading to increased anxiety symptoms. Treatment would focus on identifying and modifying maladaptive behaviors through techniques such as exposure therapy and behavior modification.
The humanistic approach would emphasize Jake's self-actualization and personal growth. They might view his anxiety as a result of a discrepancy between his self-concept and the challenges he is facing in his major.
Treatment would involve providing a supportive and empathetic environment where Jake can explore his feelings and values, with the goal of helping him align his personal goals with his academic pursuits.
The cognitive approach would focus on Jake's thoughts and beliefs about his academic performance. They would suggest that his anxiety stems from negative and distorted thinking patterns, such as excessive self-criticism or catastrophic thinking.
Treatment would involve cognitive restructuring, helping Jake identify and challenge irrational thoughts, and developing more adaptive and realistic thinking patterns.
In contemporary psychology, these approaches are not seen as mutually exclusive, but rather complementary. Psychologists recognize that a multidimensional approach, integrating elements from different perspectives, can provide a more comprehensive understanding of psychological issues.
Treatment approaches often combine techniques from various approaches to address the unique needs of each individual, emphasizing a holistic and personalized approach to mental health.

Answer: Inherited genetic variations are caused by the process of meiosis.
Inherited genetic variations are caused by the process of meiosis. Meiosis can be described as a phenomenon in which parent cell divides into four new daughter cells each having half the number of chromosomes of the parent cell. During meiosis, the phenomenon of crossing over and homologous recombination occurs which cause inherited genetic variations.
Mutations can also cause genetic variations to arise. A mutation can be described as a change in the genetic sequence which can occur naturally or can be induced. The change in the genetic sequence causes variations to arise.
