When the concentration of ________ in tissue fluid is too high, intracellular water moves into the extracellular fluid compartment.

Answers

When the concentration of electrolytes in tissue fluid is too high, intracellular water moves into the extracellular fluid compartment.

OSMOSIS:

Osmosis is the movement of water molecules from a region of higher concentration to a region of lower concentration through a semipermeable membrane.

Osmotic principle is based on concentration gradient i.e. difference in concentration across a membrane.

Electrolytes represent solute such as salts, ions, sugar etc. Therefore, when the concentration of electrolytes in tissue fluid is too high, intracellular water moves into the extracellular fluid compartment.

Which of the following is NOT an accessory gland of the male reproductive system?

Answers

Answer:

a. Testosterone gland  

Explanation:post protected

Testosterone gland is not an accessory gland of the male reproductive system.

What is Testosterone gland?

Testosterone is a hormone that is primarily produced in the testicles in males and in small amounts in the ovaries and adrenal glands in females. It is a vital hormone that plays a critical role in the development of male reproductive tissues and secondary sexual characteristics, such as muscle mass, bone density, and body hair growth.

Testosterone is also essential for maintaining sex drive and overall physical health in both men and women. The production of testosterone is regulated by the hypothalamus and pituitary gland in the brain, which release signals to the testes to produce testosterone.

Certain medical conditions, lifestyle factors, and aging can affect testosterone production and levels, which can have significant impacts on health and wellbeing. Treatment options are available to address testosterone deficiencies and imbalances.

7. Explain the following: All compounds are substances,
but not all substances are compounds."

Answers

Answer:

Below

Explanation:

"All compounds are substances,  but not all substances are compounds."

In simpler terms, let us use an example. Look at the image below.

In a big circle, there are substances. And in the small there are compounds. Since the compounds are inside the big circle, they are compounds, but as you can see, the substances are not inside the compounds so they cannot be considered compounds.

If you think about it, a substance is anything. So would you think a bottle, for instance, is a compound? A compound is a mixture of molecules. And a substance is most likely a combination of atoms, which are elements.

When is the kinetic energy of a pendulum the least?

Question 5 options:

On the path beginning the upwards swing.


Half the distance on the path traveling back down.


At the bottom of the swing.


At the top of the swing where it briefly stops before changing direction.

Answers

[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]

The Correct choice is ~

" At the top of the swing where it briefly stops before changing direction "

before changing the direction, it stops for a while therefore the kinetics energy is almost zero at that particular moment ~

The answer is D - At the top of the swing where it briefly stops before changing direction. This is where potential energy is at its highest, meaning that kinetic energy is at its lowest. When the pendulum is beginning its upwards swing, it has a lot of kinetic energy. When it is half the distance traveling down it also has lots kinetic energy. When it is at the bottom it as well has a lot of kinetic energy. The only time where the kinetic energy is least is when the pendulum stops to change direction. Any form of stopping forced the object to loose its kinetic energy.

!! hope that helps love you guys !!

The movement of water across cellular membranes through aquaporins is known as osmosis. Water moves down the concentration gradient. The fourth option is the correct answer.

How do molecules move across the cell membrane?

Molecules can pass the cell membrane both actively and passively. In passive transport, no energy or ATP is required. Molecules can move from a higher concentration to a lower concentration.

Diffusion and osmosis are examples of passive transports. In diffusion, gases and other small molecules pass the cell membrane from a higher to a lower concentration. Water is a polar molecule, so it doesn't pass the membrane due to its nonpolar nature. Cells have aquaporin channels that are made for water.

Through aquaporins, water passes into the cell. This is called osmosis. In active transport, energy is required. When a molecule passes from a lower concentration to a higher concentration, energy is needed. An example is sodium-potassium ATPase.

Hence, the correct answer is osmosis. The fourth option is the correct answer.

most of the energy that your brain uses comes from

Answers

Answer:

Glucose

Explanation:

The brain is an energy-hungry organ. Despite comprising only 2 percent of the body’s weight, the brain gobbles up more than 20 percent of daily energy intake. Because the brain demands such high amounts of energy, the foods we consume greatly affect brain function, including everything from learning and memory to emotions.

Just like other cells in the body, brain cells use a form of sugar called glucose to fuel cellular activities. This energy comes from the foods we consume daily and is regularly delivered to brain cells (called neurons) through the blood.  

Studies suggest the quality of the foods consumed over a lifetime affects the structure and function of the brain. For instance, the consumption of omega-3 fatty acids found in fish provides structural material to maintain neurons. Studies also suggest omega-3 fatty acids are essential for the transmission of information between brain cells. In contrast, foods that are rich in sugars and saturated fats have been found to promote oxidative stress, which leads to damage to cell membranes.  

The food you eat also affects molecules in the brain that support cognition. Some foods, such as those with turmeric, support cognition by helping to maintain molecular events related to energy metabolism.

Recent studies suggest lifestyle choices that affect the metabolism of nerve cells, such as diet and exercise, may in some cases provide a non-invasive and effective strategy to counteract neurological and cognitive disorders.
