What is skin cancer and how does it occur?

Answers

Answer 1

Answer:

Skin cancer refers to the abnormal activity of skin cells associated with carcinogenesis

Explanation:

This disease is associated with the DNA damage (mutations) often caused by  the irrational exposition to UV sun rays that trigger DNA mutations capable of both inactivating tumor suppresor genes and activating oncogenes

Answer 2

Answer:

Skin cancer is the uncontrolled growth of skin cells.  

Explanation:

They grow and divide without stopping, and they can spread to other places in your body.

Skin cancer is frequently caused by exposure to ultraviolet rays from the sun or from tanning beds.

The UV light can cause mutations in your skin’s DNA so it can’t control skin cell growth. The result is often skin cancer.

The nitrogenous bases are near the center of the DNA molecule.

Answers

Answer:

The correct answers: B, C and D.

Explanation:

X-ray diffraction studies of the DNA reveal the following:The DNA is comprised of two strands which are coiled around each other in the shape of a helix.The backbone of the DNA is made up of phosphate and deoxyribose groups, alternately, which are exposed towards the outside of the helix.The nitrogenous bases which form the hydrogen bonds that link the two helices are directed towards the centre of the helix.

The atomic and molecular arrangement of the compound subjected to the X- rays can be defined by using the X-ray diffraction method.

The photograph enabled Watson and Crick to develop their DNA molecule structure and revealed:

Option B. The DNA strands are twisted around each other.

Option C. There are two strands in the DNA molecule.

Option D. The nitrogenous bases are near the centre of the DNA molecule.

This can be explained as:

The DNA fragment comprises two antiparallel strands.

They are in a twisting style and form a helical formation.

The DNA molecule includes sugar, nucleotide and phosphate in alternative styles in helical formations.

The phosphate and the sugar are projected to face outwards, while the nitrogenous bases face inwards.

Therefore, DNA is a double helical arrangement with two antiparallel strands containing nitrogenous bases, sugar and phosphates.

what prevents blood movement from left ventricle to left atrium​

Answers

The Mitral valve which is also known as left atrioventricular prevents blood movement from left ventricle to left atrium.

Explanation:

Human heart is four chambered.Two of these are receiving chambers known as atria and the other two are distributing chamber known as Ventricles.Atria are superior chambers and ventricles are inferior chambers.The heart has four valves broadly grouped as Atrioventricular valves and Semi lunar valves. Atrioventricular valves allows flow of blood from atria to ventricle. These are tricuspid valve and bicuspid valve.Semi-lunar valves allow blood to pass out of the heart. These include the pulmonary and aortic valves.The pulmonary valve allows blood to flow from right ventricle  to the heart while aortic valve allows blood to flow from left ventricle to the Aorta.The Tricuspid valve located between the right atrium and right ventricle allows blood to flow from right atrium to the right ventricle. The Bicuspid valve ( Mitral valve)  located between the left atrium and left ventricle allows the blood flow from left atria to left ventricle.Valves maintain the unidirectional flow of blood and thus prevent its back flow.
Final answer:

The mitral valve prevents blood from flowing backwards from the left ventricle to the left atrium in the heart. It's a one-way valve that closes when the left ventricle contracts, ensuring blood flows in the correct direction. Malfunction of this valve can lead to heart problems.

Explanation:

The structure that prevents blood movement from the left ventricle back to the left atrium is called the mitral valve, also known as the bicuspid valve. This valve is a one-way valve that ensures blood flows in the correct direction. When the left ventricle contracts, this valve closes tightly to prevent blood from flowing backwards into the left atrium.

The mitral valve's functionality is crucial for the efficient functioning of the heart, as any disruption in the valve can lead to health complications such as mitral valve prolapse, mitral regurgitation, or heart murmurs.

Two steel balls that are the same mass and size are rolled with the same force across different level surfaces.
The ball rolling across carpet will come to a stop faster than the one rolling across concrete because of
A) air resistance.
B) friction.
C) gravity.
D) speed.

Answers

Answer:

The reason why the ball rolling across carpet will come to a stop faster than the one rolling across concrete is the friction (option B).

Explanation:

The contact surface on which the balls move is different. Irregularities in the carpet cause the ball in it to stop faster. The concrete surface is less irregular, and allows the ball to move a little more and then stop. This is due to friction.

In physics, friction is a force that is capable of opposing movement, since the contact of two surfaces limits its movement. A smooth surface produces less friction than a rough or irregular surface.

Since the friction that stops both balls occurs when they are in motion, it is called dynamic friction, that is, the force that causes a moving body to stop.

Friction https://brainly.com/question/1714663

The ball rolling across the carpet will come to a stop faster than the one rolling across the concrete because of friction.

Frictional force refers to the resistance force experienced by a moving object on a surface as a result of the opposing tendency of the surface.The smoother a surface is, the lower the frictional force it offers, and the more coarse a surface is, the more frictional force it offers.

Two steel balls rolling on two different surfaces would experience similar forces. However, a carpeted surface is more coarse and irregular than a concreted surface.

Thus, the frictional force on the carpeted surface would be more and the ball would stop faster as opposed to the concrete surface.

Explanation:

Internal environment of an organism is water-based where the body cells exist.The fluid known as tissue fluid washes the body cells.Oxygen and nutrients are carried to the cells from Internal Transport system of the body. Interstitial fluid is found in between the spaces of cell. It comes out from the substances that flow out from the blood capillaries. Oldertissue fluid is replaced by new fluid where older flood drains towards lymph vessels.
Final answer:

The internal environment is the environment within an organism's body, including inside a cell and the surrounding interstitial fluid. It is closely related to the outside world as changes in the external environment can affect the internal environment.

Explanation:

The internal environment of an organism is the environment within its body, made up of the cell's inside environment and the interstitial fluid that surrounds the cells. The inside of a cell and the interstitial fluid together create a stable environment that allows the cells to function properly and maintain homeostasis.

The internal environment is crucially related to the outside world. Changes in the external environment can directly or indirectly affect the internal environment. For instance, changes in temperature can affect the cellular metabolism while changes in nutrient composition can influence the available substances for the cells. Thus, an organism needs to constantly adapt to changes in the external environment to keep its internal environment steady and function normally.

Some viruses are RNA-based—ejecting their single-stranded RNA into the cell of a host. Let's say we are dealing with this type of virus. We also find it to be the type of RNA-based virus that has its RNA strand first converted into a complementary RNA strand using the host cell's RNA polymerase. Then this viral complementary RNA strand is used by the host cell's ribosomes to make new proteins.

If an RNA-based virus like the one we have here were to be considered a living thing, make an argument as to why the virus's RNA would be considered its primary source of heritable information. Also explain why this virus's primary source of heritable information would NOT be the DNA, RNA, or RNA polymerase of the infected cell.

Answers

The DNA, RNA or the RNA Polymerase of the infected cell would not be virus's primary source of heritable information because it has the ability to integrate into host cell and get itself replicated, also it causes infection so multiplication becomes necessary.

Explanation:

The virus has reverse transcriptase enzyme in them which works slightly different. It transcribes RNA into DNA and eventually gets integrated into the genome of the host. It is here the DNA in the host cell is transcribed and translated. Thus it is modelled to have RNA as genetic material.

When virus infects the living cell by a process called a lytic infection, it injects its genetic material into it to get replicated and increase its number and eventually bursts the infected cell. Since a virus causes infection, it has to increase in number so it uses its own genome to get replicated.

Ecosystem distribution is related to precipitation; regions that receive large amounts of precipitation are wet and therefore

Answers

Ecosystem distribution is related to precipitation; regions that receive large amounts of precipitation are wet and therefore have increased vegetation.

Explanation:

Precipitation in the form of rain and climate determines the vegetation of an ecosystem. Ecosystems with abundant rainfall will have dense vegetation and one with scarce rainfall will have limited or no vegetation.

Tropical rainforest ecosystems receive large amounts of rainfall distributed year round and have thick vegetation.

Water is the prime growth factor for plants and rainfall is the main source of water for plants. Any ecosystem, maybe a desert, grassland, fertile plain, bushlands, evergreen forest etc depend upon rainfall.

The rainfall determines the density of vegetation, the type of vegetation, greenness, structure of plants or trees like foliage, height, branching etc

Final answer:

Ecosystem distribution is related to precipitation, as high rainfall areas can sustain richer and more diverse biomes, including tropical wet forests and aquatic biomes. Conversely, regions with lower precipitation often have less diverse ecosystems. Climate change also plays a significant role in ecosystem distribution.

Explanation:

Ecosystem distribution can indeed be related to precipitation. In regions that receive large amounts of precipitation, the environment is typically wet and rich in biodiversity. This moisture can lead to the formation of various types of biomes, including tropical wet forests that exhibit high net primary productivity due to the warm temperatures, abundant water, and a year-round growing season. Other ecosystems, such as aquatic biomes, are shaped according to different factors, including density and temperature, as well as the amount of sunlight available.

On the other hand, regions with lower precipitation like deserts and the tundra have a lower primary productivity and less diverse ecosystems due to extreme temperatures and a lack of available water.

Climate change is another important factor impacting the distribution of ecosystems, as changes in temperature and greenhouse gas concentrations can affect the living conditions of various species and disrupt their habitats.

In both photosynthesis and cellular respiration, the electron transport chain (ETC) takes place in the membrane structure of the cell. However, the location within that structure varies between the two processes. In photosynthesis, which occurs in plants and some bacteria, the ETC occurs in the thylakoid membrane of the chloroplasts. Here, light energy is used to move electrons from water to NADPH. In cellular respiration, which happens in all living organisms, the ETC is located in the inner mitochondrial membrane and it helps move electrons from NADH and FADH2 to oxygen, which is then reduced to water. The flow of electrons through these ETCs creates a proton gradient that drives ATP synthesis.
