Mitochondria releases energy stored in food. Correct option is A.

Mitochondria are the cell's organelles responsible for releasing energy stored in food. They are often referred to as the "powerhouses" of the cell. Through a process called cellular respiration, mitochondria convert nutrients from food, such as glucose, into usable energy in the form of adenosine triphosphate (ATP). This energy is essential for various cellular activities and functions. Mitochondria are found in most eukaryotic cells, including animal and plant cells.

The primary function of mitochondria is to generate energy in the form of ATP through a process called cellular respiration. This process involves breaking down organic molecules, such as glucose, obtained from food to release energy. Mitochondria act as the site for several interconnected reactions that occur in different stages: glycolysis, the citric acid cycle (also known as the Krebs cycle), and the electron transport chain.

Answer: It's the Brain

Answer:

Bone with insufficient collagen has a grater chance to get fractured compared to a healthy bone.

Explanation:

Collagen is one of the most abundant fibrous protein in human body. It is made by the connective tissue cells. It forms scaffold which provides strength to the bones. Its also present in skin, muscles ad tendons. Insufficient or abnormal collagen leads to Osteogenesis imperfecta. It is a condition where bones become brittle.

Answer:

Stop the magnesium sulfate infusion.

Explanation:

The patient shown above shows magnesium sulfate toxicity so infusion of this element should be discontinued. In addition, magnesium sulfate should not be used in patients with the physical conditions shown in the above question such as poor and insufficient respiratory rate, urinary output and weak and minute reflexes.

Magnesium sulphate is indicated for replacement of magnesium levels in the treatment of hypomagnesemia, cerebral edema, eclampsia, seizure control in acute uremia, uterine tetany, control of cardiac arrhythmias and barium poisoning, but should be discontinued when patient shows signs of toxicity or exhibits the symptoms shown above.

The correct answer is B. release

Explanation:

In ecosystems, competition occurs as different organisms or species need the same limited resources such as water, territory, food or shelter and therefore compete for it, this includes competition within species and also between them. This type of interaction often leads to the disappearance of one of the organism or species interacting, which is regulated by the competitive exclusion principle that states to species competing cannot coexist. Additionally, once one of the competing species is no longer present competitive release occurs, this implies the competition ends and the remaining species can access the resources more fully. According to this, competitive release occurs when the competing species is no longer present.

Final answer:

Action potentials must be conducted in one direction to ensure efficient transmission of signals along neurons, enforced by the mechanism of the absolute refractory period that follows voltage-gated Na+ channel inactivation.

Explanation:

It is important for action potentials to only be conducted in one direction because once the voltage-gated Na+ channels open and Na+ enters the cell during depolarization, the channels become inactivated at the peak of depolarization and initiate a brief period called the absolute refractory period. During this time, the channels cannot reopen, preventing the depolarization from spreading back toward the previously opened channels.

Following depolarization, K+ channels open allowing potassium to exit the cell, facilitating repolarization. Along the axon, depolarization moves like a wave towards the axon terminals, unable to reverse direction due to the refractory period. If action potentials were able to travel in both directions, it would disrupt the signal transmission efficiency and the overall polarity of the neuronal signal.

The statement "Psychologists are supposed to make the most ethical decision they can in any circumstance." is true.

Psychologist is a person who deal with problems related to the mind, thinking, emotional and social condition of a person. They are considered doctors of psychology.

They can understand the problem by hearing the problems of the patient, and they also prescribed medicine to calm them and given them emotional support.

The main part of their job is to collect information based on the behavior and interviews of the patient and also study the function of brain. They also suggest things to do to maintain the lifestyle.

Thus, the statement is true.

Answer:

Phylum

Explanation:

In the biological classification system, categories are used to group organisms according to their similarities. The basic category is species, which is defined as similar beings who are able to reproduce naturally and generate fertile descendants.

Animals of the same species are grouped into another category, the genus. All who belong to the same genre are grouped into families, which are grouped into orders, which in turn come together in classes, assembled in phyla, and finally we have the kingdoms. Kingdoms are therefore the last category in the hierarchy and subdivided into the most basic category. So we have:

Kingdom ⇒ Phylum ⇒ Class ⇒ Order ⇒ Family ⇒ Gender ⇒ Species

From this we can conclude that the level of organization in the classification system that is directly above the level of "class" is the "phylum".

Answer: Kingdom

Explanation: In this system of classification, kingdom is always ranked the highest followed by division, class, order, family, genus, and species.

and i got it right on my test

It would take less than 5.8 seconds for the sound to travel from the calling monkey to another monkey 2 kilometers apart, based on the speed of sound at sea level

kilometers apart, we can use the speed of sound in air. The speed of sound is approximately 343 meters per second at sea level and at 20°C (68°F). To find the time, we divide the distance by the speed of sound:

Time (seconds) = Distance (meters) / Speeof sound (meters/second)

Since 2 kilometers is 2000 meters, we have:

Time = 2000 meters / 343 meters/second

Time \< 5.8 seconds

Therefore, it would take less than 5.8 seconds for the calling monkey's roar to reach another monkey if they were 2 kilometers apart in conditions similar to sea level at 20°C.

It is incorrect to state that the American Psychological Association is the sole agency that can endorse psychological research studies.

The scientific study of the behavior and mental processes is known as psychology. Psychologists work hard to learn about and fully comprehend mental states, brain structures, and behavior patterns.

Psychologists undertake basic and research activities, consult with groups and organizations, treat and diagnose patients, and educate future psychologists and those interested in other fields.

They assess intelligence as well as personality. Many psychologists work in the medical field.

Although the agency is one of the prestigious psychology associations in the United States, and it is an organization that reflects psychologists in the United States, it is not the only organization that approves psychology research."
