when we brethe in our lungs expanding size and the ribs move upwards and inwards
when we brethe out our lungs get smaller in size and the ribs move downwards and outwards..
21% oxygen and 0.04% carbon dioxide are present in the air we take in, whereas 16.4% oxygen and 4.4% carbon dioxide are present in the air we exhale.
What is cellular respiration?This is due to the fact that when we breathe in air, our cells convert oxygen into energy while also producing carbon dioxide as a byproduct.
The same number of carbon and oxygen atoms that were transformed into carbon dioxide during respiration was also released.
With saving mass or material in this way, respiration has abided by the rule of conservation of mass.
Therefore, cellular respiration is the process by which the chemical component glucose is broken down with oxygen to create carbon dioxide and water.

On the ventral surface of the brain, you can observe the optic nerves and chiasma, the pituitary gland, and the mammillary bodies. These externally visible structures form the floor of the Diencephalon
"Diencephalon" is the term used to describe the structures around the 3rd ventricle and form the nucleus of the cerebrum "big brain", the members of the diencephalon are the thalamus, hypothalamus, subthalamus and epithalamus.
Diencephalon Function
The diencephalon plays a role in the motor control of sensory information exchange and the control of autonomic functions of various parts of the body. Examples of some activities that involve the work of the diencephalon are chewing, seeing, eye movements, facial expressions, hearing, breathing, swallowing, smelling and regulating body balance.
Structure and Parts of the Diencephalon
Diencephalon consists of 4 structures that have their respective specific tasks, namely:
1. Thalamus
The thalamus is a structure located in the middle of the brain, precisely between the cerebral cortex and the midbrain. The word thalamus comes from the Greek word which means inner space. The main function of this gland is to convey sensory and motor signals related to consciousness, sleep and alertness to the brain cortex, the thalamus is a suborgan of the diencephalon.
2. Hypothalamus
The hypothalamus is the part of the brain that is the control center of the autonomic system, the hypothalamus is located just above the brainstem. This gland-shaped organ is part of the endocrine system. In humans, the hypothalamus is about the size of a pea and accounts for 1% of the total brain weight.
3. Subthalamus
The subthalamus is an important extrapyramidal motor nucleus that has many connections with other nervous system nuclei. The function of the subthalamus is not yet fully understood, but if there is an abnormality in this part, there will be abnormalities in the movement of the foot or hand that hit strongly on one side of the body.
4. Epithalamus
The epithalamus is a narrow band of nerve tissue that forms the roof of the diencephalon, functions in regulating the body's circadian rhythm and inhibits gonadotropic hormones.

Most viruses will leave a host cell by bursting the cell, a process called lysis, or by pushing through the cell membrane while taking some of that membrane with it, a process called budding.
Enveloped viruses generally are released from the host cell by budding. During this process, the virus obtains its envelope, which is a modified piece of the host's plasma or other, internal membrane. Through budding, a bit of the host cell membrane becomes part of the virus.
On the other hand, lysis destroys the host cell. A lytic infection eventually leads to cell lysis, which is accompanied by the freeing of newly produced virus particles and cell debris into the environment. Cell lysis is a common result of viral infection.

During volume changes in the thoracic cavity, what is primarily responsible for changes in length?.
During volume changes in the thoracic cavity, the diaphragm is primarily responsible for changes in length.
The diaphragm flattens and tightens during inhalation, and the chest cavity widens. A vacuum is produced by the contraction, drawing air into the lungs. The diaphragm relaxes and assumes its dome-like form during exhalation, forcing air from the lungs. This implies that when the volume of the thoracic cavity changes during inhalation and exhalation, the diaphragm plays a vital role in length.
The external intercostal muscles, internal intercostal muscles, innermost intercostal muscles, sub-costalis, and transversal thoracic are the five muscles that make up the thoracic wall. During respiration, the volume of thoracic cavity is predominantly altered by these muscles.

If you were able to find a drug that could inhibit the reactivation of telomerase activity in cancer cells, the cancer cells would slowly erode their chromosome ends.
Telomerase is also known as terminal transferase. Telomerase is an enzyme found inside our cells that may be linked to aging. It caps our DNA strands with short, repetitive "caps." These caps are known as "telomeres." Telomeres protect the chromosome's end from DNA damage or fusion with neighboring chromosomes. When our cells divide, they must replicate their DNA in order for each daughter cell to receive a complete set of operating instructions. However, with each cell division, a small portion of the protective telomeres on the DNA strand are lost. Telomerase is active in gametes and most cancer cells, but is absent or present in very low levels in most somatic cells.

Environment impacts freshwater aquaculture include nutrient overload and escape of exotic species.
When the aquaculture sector first started to take off, there were a few things that made it difficult for the sector to produce fish sustainably. The goal of fish farming has never been to harm the environment; rather, it is to improve food security.
Environmental issues did, however, develop. There was no lack of unfavorable press, and these reports have stuck with the general public. Nutrient and effluent build-ups, the negative effects of fish farms on nearby wild fisheries due to disease and escape, and environmental damage as a result of the site's location were common criticisms.
Aquaculture's harmful environmental effects are complex. When there are many fish in one place, nutrients might accumulate. The trash that fish produce has the potential to accumulate in the neighborhood. Algal blooms and dead zones may result from the water's oxygen being depleted in this way. Antibiotic use by farmers to prevent disease has raised concerns about the drugs' impact on the ecosystem surrounding the cages, including wild fish. Many people were also concerned that the escaped non-native fish would increase food competition among wild fish, possibly driving out the native fish.
