in humans, advanced aging mimics many symptoms of mitochondrial dysfunction. This provides support for:
Savatey [412]

The mitochondrial dysfunction has emerged as one of the key hallmarks aging process and is linked to the development of numerous age-related pathologies including metabolic syndrome, neurodegenerative disorders, cardiovascular diseases and cancer.

<h3>Mitochondrial dysfunction </h3>

Chronic (long-term), hereditary, and frequently inherited ailments known as mitochondrial illnesses take place when mitochondria are unable to create enough energy for the body to function normally. When a condition is inherited, it indicates that parents have passed it on to their offspring. In addition to developing at any age, mitochondrial illnesses can be present at birth.

Affected organs by mitochondrial illnesses include the brain, nerves, muscles, kidneys, heart, liver, eyes, ears, and pancreas. They can also affect the cells of the kidneys. When the mitochondria don't perform as well as they should as a result of another illness or condition, mitochondrial dysfunction arises.

All the following rely on ATP as a source of energy except
JulsSmile [24]

Answer:

b. diffusion and osmosis across semi-permeable membranes

Explanation:

ATP (adenosine triphosphate) is a high energy carrying molecule in the system of living organisms. It posseses the ability to store and release energy for use by organisms during biochemical activities. However, some processes do not require ATP to occur and are called PASSIVE TRANSPORT while those that require energy (ATP) are called ACTIVE TRANSPORT.

In the above options, the processes listed as follows require ATP to occur:

- The active transport of glucose from the small intestine to the blood

- The movement of the flagella of sperm for motility

- Exocytosis of waste substances across a semi-permeable membrane

However, the diffusion and osmosis across semi-permeable membranes, which is a passive transport does not require ATP.

Which best describes the cycle that ensures fresh water, which is vital for carrying out metabolic processes, is available?
max2010maxim [7]

Answer: B.  evaporation, condensation, precipitation

Explanation:

The cycle that ensures that fresh water is available is called the Hydrological cycle and it involves several key processes.

As it is a cycle, none of the processes can be considered first but if any could, it would be evaporation. This is when water on the surface is heated and becomes water vapor (gas) and rises towards the atmosphere.

Condensation occurs as the water vapor rises because the further up you go, the colder it gets. These water vapor particles will thus condense and clump together to form clouds.

These clouds keep getting larger until they are too heavy to be carried by the atmosphere in which case they fall to the ground as rain the process known as precipitation.

These waves are traveling at the same speed. Which wave has the highest frequency?
Dmitry [639]

Wave of option A has the highest frequency.

Option A.

<h3><u>Explanation:</u></h3>

Frequency is defined as the total number of complete waves in an unit time. A complete wave consists of a complete cycle of the amplitudes of waves.

In all the figures, we see transverse waves. They have the mean position denoted by a straight line, and the waves do oscillate up and down to complete a full cycle. The most number of waves in a given time has the highest frequency. If we count the full number of waves in the particular given time, Wave A has 5.75 complete waves, wave B has 3.5 complete waves, wave C has 2 complete waves and the wave D has 2.75 complete waves. So the wave A has highest number of complete oscillations in a given time. So wave A has highest frequency.
