Mutated EGFR can lead to cancer (especially lung cancer).

A mutation in EGFR is associated with uncontrolled tumor growth, which can accelerate cancer progression.

Epidermal Growth Factor Receptor (EGFR) receptors are found on the surface of tumor cells and their role is to send a growth signal to the nucleus of the cell. Some lung cancer tumors may contain a mutation in their DNA that affects the EGFR. The tumor is said to be "positive for EGFR mutations".

Tumor cells with EGFR mutations are highly sensitive to cancer treatments called "Targeted Therapies" or "EGFR Tyrosine Kinase Inhibitors".

Answer:

Vitamin E supplements may prevent coronary heart disease , support immune function, prevent inflammation , promote eye health, and lower the risk of cancer.

Red blood cells, white blood cells, nerve cells, and lung cells need high amounts of vitamin E due to their high polyunsaturated fatty acid content and exposure to oxidative stress. Vitamin E acts as an antioxidant, preventing lipid peroxidation in cell membranes and working in conjunction with selenium to maintain cellular health.

The cells such as red blood cells, white blood cells, nerve cells, and lung cells require high amounts of vitamin E because they are particularly susceptible to oxidative damage from free radicals. Vitamin E serves as a powerful antioxidant that protects the polyunsaturated fatty acids present in the cell membranes from oxidation. The cells' high degree of unsaturation in their membrane lipids makes them vulnerable to lipid peroxidation, which can be detrimental to their function and integrity.

Vitamin E, especially in the form of alpha-tocopherol, prevents the oxidation of these fats by acting as a free radical scavenger. It donates electrons to free radicals, stopping the chain reaction of lipid peroxidation. In addition, vitamin E works by sparing or reducing the need for, selenium, which is needed for the activity of glutathione peroxidase, an enzyme that also reduces lipid peroxides and protects the cell membrane. This synergistic action is essential for maintaining cellular health, especially in cells that are exposed to higher levels of oxidative stress, such as lung cells which are constantly in contact with oxygen, and white blood cells that engage in immune responses.

Viruses are capable of surviving in low temperatures, including those found in refrigerators and freezers. They do not proliferate under such conditions, though, as they need living host cells to replicate.

Yes, the statement that viruses can survive refrigerator and freezer temperatures is true. Viruses are not living organisms in the conventional sense, thus they don't have a metabolic rate that can be affected by temperature. Instead, they exist as particles and can remain infectious in a variety of conditions, including low temperatures such as those of a refrigerator or freezer. For instance, the influenza virus and the Covid-19 virus can both survive in cold temperatures. However, this varies between different types of viruses. While they can survive, they do not proliferate in these conditions because they require living host cells in order to replicate.

Yes, viruses can survive both refrigerator and freezer temperatures. Their ability to reproduce is often inhibited at low temperatures, but many can remain dormant or resilient. However, extreme cold can lead to physical changes in these viruses, which might inhibit their ability to infect host cells.

Yes, the statement that viruses can survive both refrigerator and freezer temperatures is true. Some viruses, like certain types of influenza, have shown the ability to survive outside of a living host cell for extended periods of time, sometimes from 48 hours to 17 days. On the other hand, some pathogens like cold-causing rhinoviruses are more fragile and tend to survive for a shorter duration, typically less than a day.

When exposed to low temperatures, pathogens do not typically reproduce, but they can remain dormant or resilient. Refrigerator temperatures, which range from 0 °C to 7 °C, slow down microbial metabolism, inhibiting growth and helping to preserve the pathogen. Similarly, even ultra-low temperatures of -70 °C or lower can be withstood by some types of pathogens for extended periods.

However, extreme cold temperatures can lead to physical changes in viruses, affecting membrane fluidity and other biological processes. These changes may inhibit the ability of the virus to infect host cells. Thus, while cold temperatures do not universally destroy viruses, they can very often inhibit their ability to infect host cells because of the changes in membrane fluidity and the slowing down of biological processes.

Answer:

Menstrual flow and ovulation

Explanation:

The menstrual cycle is the hormones regulated the complex process. In this process, endometrium (a thickened lining of uterus wall) ruptures. Rupturing of endometrium results into the menstrual fluid which contains blood, cells from the lining of the uterus and mucus. The flow of menstrual fluid from the vagina is called menstruation. This process is to prepare the woman for expected fertilization.

Menstruation marks the end of one cycle and the release of ova from one of the ovary is beginning of next menstruation that occurs almost 14 days before menstrual flow.

The internal structures of a kidney that funnel urine into the ureter are the calyces. Specifically, urine flows from the nephrons into the renal tubules and then into the renal pyramids. The urine then enters the minor calyces, flows into the major calyces, and these converge to form the renal pelvis. The urine is then supposed to pass from the renal pelvis into the ureters.

The internal kidney structures that funnel the urine into the renal pelvis of the ureter are the calyces. As urine is formed in the kidney, it drains into these structures. Specifically, in terms of the kidney's anatomy, the urine flows first into the minor calyces, then into the major calyces, which merge to form the funnel-shaped renal pelvis at the hilum of the kidney. From there, the urine passes into the ureters. Below is a step-by-step breakdown of this process:

However, it's worth noting that due to Mike's injury, the process may be disrupted at the step where the urine is supposed to pass from the renal pelvis into his injured ureter.

Grass often dies near roads that have been salted to remove ice in winter because salt has spread to the grass cover. Then the water goes into the ice, because the grass is attracted to the salty ice water. Consequently, it dehydrates the plant cell, removing excess water, so it dies, as it can no longer perform the proper function of the cell.

A transitional fossil represents an evolutionary intermediate between older and newer species, often exhibiting traits common to both. They were not universally poorly adapted to their environments, nor did they exist only for short periods. A notable example of a transitional fossil is the Archaeopteryx.

A transitional fossil is a fossil that represents an evolutionary intermediate between older and younger species. These fossils exhibit traits common to both an ancestral group and its derived descendant group, hence they are considered 'transitional' between the two.

Contrary to one of the statements in the question, transitional fossils were not necessarily poorly adapted to their environments. Some may have flourished in their environments, but eventually went extinct due to various factors such as changing environmental conditions or competition. Furthermore, the duration of existence of transitional fossils can vary. Some may have existed for a relatively short period, while others persisted for much longer periods.

An example of a transitional fossil is the Archaeopteryx. This fossil, which is approximately 150 million years old, is considered to be a transitional form between dinosaurs and birds.

Answer:

A respirometer is a device that is used to measure the consumption rate of oxygen by any living organism.

So as the oxygen uses by the organism, the pressure of oxygen in the respirometer decreases and as the pressure decrease some amount of water enters the respirometer.  

So according to the consumption of oxygen water will move inside the respirometer due to a reduction in pressure in respirometer. So the rate of respiration can be calculated because the amount of water enters is directly proportional to the amount of oxygen consumed by an organism.

Scientific knowledge is very dynamic, it changes all the time based on emergence of new proof. The fossil provided new proof about human lifestyles thousands of years ago.

European rabbits in Australia are an example of an invasive species causing significant ecological and economic damage. Biological control through viruses like myxoma was used to manage their population, with initial success followed by the development of rabbit resistance.

The introduction of European rabbits to Australia is an example of an invasive species disrupting the local ecosystem. Initially introduced for sport hunting, their population exploded due to the lack of natural predators. The competition for food between rabbits and domestic animals like sheep led to severe agricultural damage. Biological control methods were introduced as a form of population management. Species like the myxoma virus and later the rabbit hemorrhagic disease virus were used to control rabbit numbers. Although initially effective, these measures saw diminishing returns as the rabbits developed resistance and the viruses became less virulent.

In summary, this is a clear case where biological control has been used to manage an invasive species that caused significant ecological and economic harm, with varied success due to the evolving resistance in the rabbit population.

The Earth has changed significantly from its infancy to the present day, with the formation of a breathable atmosphere, the development of oceans, and a decrease in geologic and volcanic activity characterizing its evolution.

The Earth has undergone numerous changes since its formation around 4.5 to 4.6 billion years ago. Initially, the Earth was a molten body that lacked an atmosphere and oceans. Over time, it cooled down, leading to significant geological changes. Three key ways in which the Earth is different today from when it first formed include:

These changes have shaped the Earth we know today, supporting a vast diversity of life and resulting in a planet that is hospitable to humans.

Today's Earth differs from its original form in its oxygen-rich atmosphere, lesser volcanic activity, and diverse biosphere due to evolution and plate tectonics.

Three ways the Earth is different today from when it was first formed are related to its atmosphere, geologic activity, and biological diversity. Initially, Earth was molten and lacked an atmosphere and oceans. Over time, the atmosphere developed predominantly from volcanic gases, and Earth's oceans were formed by the condensation of water vapor and cometary ice.

The early atmosphere had a very different composition, lacking in oxygen (O2) and rich in gases like carbon dioxide (CO2), methane (CH4), and ammonia (NH3). This atmosphere was subject to extreme radiation and intense volcanic activity. In contrast, today's atmosphere is rich in oxygen, thanks to photosynthetic organisms, and volcanic activity is less frequent and less widespread.

Furthermore, Earth has undergone tremendous geologic upheaval, shaping its crust through the dynamic process of plate tectonics. These tectonic activities have prompted significant changes in the landscape, including the formation of mountains, rift valleys, and other geological features. Lastly, the evolution of life over billions of years has transformed Earth's biodiversity, resulting in the complex ecosystems present today.
