Answer:

Temperature.

Explanation:

Ecosystem may be defined as the the biological communities and their interaction with non- living organisms. The ecosystem includes both the living and non-living organisms.

The living component of the ecosystem are plants, animals, bacteria and other microorganisms. Temperature is considered as non- living component of the ecosystem and it can influence the structure of the ecosystem.

Thus, the correct answer is option (4).

     For this question, what you need to pay attention to is what the process of photosynthesis does for the plant, once you know that, the answer is pretty much over.

     Being brief, the photosynthesis uses the light to create energy, and this energy is used to maintain the metabolism working in a way that the plant won't miss this energy. So, this process creates a molecule called glucose, that's the energy for the plant, and it's used for many functions within it. For example, plants use glucose to make cellulose, the main part of their cell wall. Starch is too, made by using glucose, and it's used as a reservation of energy for the plant.

The mitochondria in a cell produce most of the cell's energy by carrying out a process called cellular respiration, which converts the chemical energy in glucose and other nutrients into ATP, the main energy-carrying molecule.

The mitochondria in a cell are usually referred to as the 'powerhouses' or 'energy factories' because they are responsible for producing adenosine triphosphate (ATP), the main energy-carrying molecule of a cell. This process, known as cellular respiration, uses the chemical energy in glucose and other nutrients to make ATP. Organisms obtain energy from their environment and convert it into a form that they can use to do work. This energy is stored within organic molecules like sugars and fats, and is converted through a series of cellular chemical reactions into ATP molecules. Energy in ATP molecules is easily accessible to do work such as powering the motion of cilia or flagella, and contracting muscle fibers to create movement.

Answer:

The carbon dioxide concentration will be constant by diffusion and the salt balance occurs by osmosis in human body. The maintenance of constant internal environment is homeostasis.

Explanation:

Homeostasis is the process of keeping a constant internal environment. Here all the physiological activities should be at a constant level. This includes the maintenance of the blood sugar level, carbon dioxide concentration, salt, temperature regulation.  

The salt balance is maintained in the body by aldosterone hormone or ADH hormone. It is a steroid hormone secreted from the adrenal cortex. When the salt concentration is more in the blood, aldosterone secretion will be more. It helps to reabsorb more salt by the distal convoluted tubule.  

When the salt concentration is less in the body the secretion of the ADH hormone is less. This maintains the osmoregulation of the body by keeping the sodium level constant.  

Another example is the maintenance of carbon dioxide concentration in the blood. In the blood, the carbon dioxide concentration is less than the oxygen. Sometimes due to physical exercise, cellular respiration increases the level of carbon dioxide.  

In this situation, the medulla oblongata sends the signal to the heart. Then the heart helps carry more carbon dioxide in the blood and reaches the lungs. Thus the heartbeat and breathing rate will more. This expels out the excess carbon dioxide from the body.  

This process happens by diffusion while the salt balance has done by osmosis.

The three types of graphs commonly used are line graphs, pie graphs, and bar graphs. Line graphs show the relationship between two variables over time, pie graphs display parts-of-a-whole data, and bar graphs are used to compare different categories of data.

Three types of graphs commonly used are line graphs, pie graphs (also known as circle graphs), and bar graphs. Line graphs are most appropriate when showing the relationship between two variables measured on the horizontal and vertical axes, such as tracking temperature changes over time. Pie graphs are best for displaying parts-of-a-whole data, such as the proportions of different types of animals in a zoo. Bar graphs are often used to compare different categories or groups of data, like comparing the sales figures of different car models.

Using antibacterial wipes can contribute to the mutation of bacteria by applying selective pressure that favors resistant strains, which can survive and proliferate. Hyperevolution and horizontal gene transfer are mechanisms that can facilitate the spread of antibiotic resistance. While most mutations are harmful, in large populations, the few beneficial mutations can lead to antibiotic-resistant bacteria.

When bacteria come under stress from agents like antibacterial wipes, which often contain antibiotics or antiseptics, they can undergo a process that increases mutation rates as a form of self-defense. This heightened state of mutation, known as hyperevolution, allows the bacterial population a greater chance of developing mutations that could lead to antibiotic resistance. Most mutations are detrimental, but in a large population, some bacteria may acquire beneficial mutations that allow them to survive and thrive despite the presence of antibiotics, thereby increasing the frequency of resistant bacteria over time through natural selection.

Furthermore, the exposure to antibiotics does not 'cause' bacteria to become drug-resistant - the resistant genes are often already present in the bacterial population. However, the use of antibacterial substances can apply selective pressure, favoring bacteria that either already possess resistance genes or those that acquire them through spontaneous mutation or horizontal gene transfer. Horizontal gene transfer allows the exchange of DNA between bacteria, spreading resistance traits more quickly than through mutation alone.

It's also critical to understand that some bacteria can survive antibiotic treatment without being resistant by entering a state of dormancy, known as antibiotic tolerance. These 'dormant persisters' halt growth in the presence of antibiotics, avoiding being killed, but they do not possess or acquire resistance genes. Finally, the development and spread of antibiotic-resistant bacteria are major public health concerns, with CDC estimates indicating over two million infections from resistant bacteria annually in the United States.
