1. Photosynthesis refers to the procedure by which plants and some other species utilize the energy in the form of sunlight to generate glucose from carbon dioxide and water. The chlorophyll present in the leaves captivates the light energy needed to form glucose. As chlorophyll is green, so it absorbs the blue and red parts of the electromagnetic spectrum and reflects the green part of the spectrum.
2. Hydrocarbons are the organic components, which are formed of only carbon and hydrogen atoms. They are found in various places, like natural gas and crude oil.
3. A single molecule of phospholipid exhibits a phosphate group on one end known as the head and the two side by side chains of fatty acids, which forms the lipid tails. The phosphate group is charged negatively, forming the head polar and hydrophilic, or water-loving.
4. All the amino acids are bonded together to form long chains, the bond is known as a peptide bond. In an amino acid, the alpha carbon is bound with a hydrogen atom as well as a unique side chain, or R group. Each of the 20 amino acids differentiates from each other due to the presence of the unique R group, or the side chain.

List three factors that caused a decrease in the rabbit population?
The density dependent factors are factors whose effects on the size or growth of the population vary with the population density. There are many types of density dependent dependent factors such as; availability of food, predation, disease, and migration. However the main factor is the availability of food.
Decrease in rabbit population can be caused by extreme weather conditions or natural disasters increased predation and decrease in available food resources.
Explanation:There are various factors that can lead to a decrease in the rabbit population. Firstly weather conditions and natural disasters can negatively impact the rabbit population as extreme cold forest fires or floods can lead to mortality regardless of population density. Secondly an increase in predation can lead to a decrease as well. For example if the population of a predator like wolves or coyotes increases it could lead to more rabbits being hunted and thus a decrease in their population. Lastly a decrease in available food resources can also cause the population to decrease as it leads to less successful development and reproduction in rabbits.

How did the artificial selection practiced by pigeon breeders influence Darwin's theory of evolution by natural selection?
The study of artificial selection by Darwin helped him to establish his theory of evolution via natural selection. One of the animals Darwin examined in detail was the domestic rock pigeon. In the 1850s breeding of pigeons was an ancient past time, thus, Darwin decided to keep and breed the pigeons by himself.
While studying pigeons, Darwin established scrupulous determinations of their skeletons and wondered at the breeds' distinct colors, behaviors, and proportions. He also observed the patterns of inheritance of various features, and he demonstrated that birds of very distinct breeds can, however, generate fertile offspring. Thus, supporting the theory that they all originated from a single species.
Answer:
Answer for PLATO is ; Darwin concluded that if traits in captive pigeons could be selectively passed on to offspring, the selection of traits could also happen in nature.

PLEASE ANSWER. E. coli is a species of bacteria that causes many different infections in humans. Certain E. coli strains have developed resistance to antibiotics, making infections with these strains difficult to treat. How do bacteria such as E. coli, which reproduce asexually, gain new traits such as antibiotic resistance?
A.
by undergoing spontaneous mutations when they replicate, which increases genetic variation in a population
B.
by mutating their DNA in response to environmental conditions to gain beneficial traits
C.
by adapting to changes in environmental conditions without undergoing changes in their DNA
D.
by producing offspring with new gene assortments from genetic recombination, which increases diversity in a population
The correct answer is option A. Bacteria like E. coli gain new traits, such as antibiotic resistance by undergoing spontaneous mutations when they replicate, which increases genetic variation in a population.
Option A is correct because bacteria reproduce asexually, and during replication, spontaneous mutations can occur. These mutations introduce genetic variation, which can include traits like antibiotic resistance.
Why other options are incorrect:
Option B is incorrect because. Bacteria don’t intentionally mutate their DNA in response to environmental changes. Mutations occur randomly and are not directed by the environment.Option C is incorrect because. Bacteria adapt through genetic changes, not just by modifying their behavior. Adaptation involves genetic mutations that lead to new traits.Option D is incorrect because. Bacteria reproduce asexually, so they don’t use genetic recombination or gene assortment like sexually reproducing organisms to increase diversity.how does fever help fight germs
Fever is a state of body in which body temperature is above the normal temperature ( 37 °C).
Due to elevated temperature germs cannot colonize, reproduce and spread disease because their optimum temperature ( 37 °C) is not available due to fever.
Answer:
Every cell requires a particular temperature to grow, even the bacterial cell requires optimum temperature to grow to cause infection inside the human body.
The normal body temperature allows many bacteria to grow inside the body causing infection. But during the time of fever there is a slight elevation in the temperature of the body.
This elevated temperature does not allows the growth of certain bacteria causing infection.This is how fever prevents infection.
Which type of macromolecule regulates cell processes or transports material into and out of cells?
Answer:
Proteins
Explanation:
Proteins perform several functions such as regulation of cellular processes and transport of materials in and out of the cells.
Some proteins serve as enzymes and catalyze the cellular processes and thereby regulate the rate of the product formation. Proteins such as transcription factors regulate the expression of several genes. Some hormones are proteins or derived proteins. Insulin is an example which in turn regulates the blood glucose levels in the body.
Some of the proteins present in the cell membrane serve as channels and pumps to allow the transport of various substances across the cell membrane.
why is a helium atom more stable than a hydrogen atom?
Two electrons completely fill its outermost electron shell
A helium atom is more stable than a hydrogen atom due to its stronger nuclear force complete first electron shell and valence shell configuration.
Explanation:A helium atom is more stable than a hydrogen atom for several reasons. Firstly, a helium atom has two protons in its nucleus, while a hydrogen atom has only one. The additional proton in the helium atom contributes to a stronger nuclear force making the helium atom more stable. Secondly, the helium atom has two electrons which fill its first electron shell completely resulting in a stable configuration.
On the other hand a hydrogen atom has one electron meaning its first electron shell is not completely filled, making it less stable than helium. Lastly the valence shell of helium contains two electrons which provides it with stability as it already satisfies the octet rule. Conversely hydrogen's valence shell contains only one electron making it more likely to react with other atoms to achieve stability.

What type of graph is best for showing a relationship between two variables? A) pie graph B) bar graph C) line graph D) circle graph
Option C) A line graph is the best option for illustrating the relationship between two variables that are changing, such as displaying economic trends over time.
When it comes to showing a relationship between two variables, a line graph is often the most effective graph to use. This type of graph is particularly useful for illustrating how two variables change in relation to each other. For instance, when tracking economic data such as the unemployment rate over time, a line graph can clearly display the trends and patterns.
In comparison, other types of graphs like a pie graph or bar graph, serve different purposes. A pie graph is best suited for showing how a whole is divided into parts, indicating percentages or proportions. Meanwhile, a bar graph is useful when you want to compare different groups or categories, where the height of each bar reflects a particular value.
Therefore, the correct answer is option C) line graph.

What is happening when the cells start to swell up with water
the cell goes into osmosis and goes into hypnotic solution
Answer:
The correct answer is cell will burst.
Explanation:
When a cell takes up water from the environment it will swell up and will become flaccid. This usually happens when a cell is placed in the hypotonic solution with a high concentration of water outside and low solute and the water will move into the cell through osmosis.
If the excess water is not removed from the cell the cell will burst or lyse.
Thus, the cell will burst is the correct answer.

Rising temperatures in the Arctic Ocean can lead to large die-offs of phytoplankton, which are autotrophs. What would most likely happen in an Arctic ecosystem if the phytoplankton population decreased?
Phytoplankton refers to the microscopic marine species that thrive at the bottom of the food chain. They obtain their energy from carbon dioxide via photosynthesis, like plants and thus are very essential in carbon cycling.
Phytoplankton forms the base of almost every ocean food web. Thus, it can be stated that they make the majority of other ocean life possible. They are the source of food for zooplankton and small fishes, as well as for larger animals like jellyfish and whales.
Thus, if the population of phytoplankton gets declined, it will indirectly affect other species in the aquatic ecosystem. It can also be said that with the decrease in the population of phytoplankton, the population of other major species in the ecosystem also gets a decline.
Answer:
The populations of all other organisms in the food web would decrease because there would be less energy available in the ecosystem.

what changes to the environment can affect the activity of enzymes
an increase in temperature can increase enzyme activity (but not too high) and a cooler temperature decreases activity, an effect on Ph and this is not so much environment but how many enzymes there are in total
Changes in temperature, pH levels, and substrate concentration can significantly affect the activity of enzymes.
Enzymes are highly sensitive to their environment. Temperature alterations can either increase or decrease enzyme activity. Most enzymes work optimally within a specific temperature range, and deviations from this range can denature or slow down their activity. Similarly, changes in pH levels can alter the ionization of amino acids within the enzyme's active site, affecting its ability to bind with substrates. Enzymes have specific pH optima, and deviations from this optimum can lead to reduced activity.
Substrate concentration impacts enzyme activity. As substrate concentration increases, the rate of enzyme-catalyzed reactions generally rises, but this increase is limited by factors such as the enzyme's saturation point. These environmental factors play crucial roles in regulating enzymatic reactions, making enzymes highly adaptable to different cellular conditions.

D. Decomposition of dead organisms
A and D are the answers.
When you fill a glass at your kitchen sink for a drink, you probably don't think about where the water came from. Perhaps you should, though, because the water you drink affects your health. Consider the small town of Long Pine, Nebraska. Less than a mile from town, Long Pine Creek is fed by a wealth of underground water. When the town was built, the people of Long Pine dug a well near the creek. They installed a pump and piped the water into town. They also built a water tower to keep the water pressure even. 2 Many people who live near an aquifer get their water in this manner. An aquifer is an underground source of water. When people dig down to the level of the aquifer, water from the ground flows into the well. Some aquifers, like the one near Long Pine, are naturally clean and free from harmful chemicals, minerals, and microbes. But many aquifers are not of such good quality. Some are tainted by ammonia or bacteria. Some contain poisonous minerals such as arsenic, and some have too many minerals in them (such as salt or iron) for the water to be fit to drink. 3 Most major cities in the United States get their water from lakes or rivers. Water from lakes, rivers, or contaminated aquifers must be treated. The process is carried out in a treatment plant. Drinking water has to be free of harmful minerals, poisonous chemicals, and disease-causing bacteria. In addition, it must be acid-neutral or slightly alkaline to prevent contamination from metal in the pipes. 4 The city of York, Pennsylvania, gets its water from two artificial lakes, called reservoirs, which are filled by Codorus Creek. The water looks clear, but if you dipped a glass in it, you would see mud, organic particles, and maybe even a minnow or a dead leaf. You wouldn't want to drink it! The water goes through a screen to remove the dead leaves and aquatic animals. Then it goes to a pumping station. At the pumping station, a chemical called potassium permanganate is added to increase the amount of oxygen in the water. Oxygen helps kill germs and improves water's taste. 5 From the pumping station, the water goes to a rapid mixer. Here an ingredient called alum is added to make fine particles clump together. Powdered carbon is also added at this stage. The alum gets rid of cloudiness in the water by causing the tiny particles to settle out when the water is pumped to a settling basin. The carbon, which also settles out, absorbs bad odors and tastes. On its way to the settling basin, the water gets an injection of chlorine. 6 The water stays in the basin while the particles, called "floc," sink to the bottom. Afterward, the almost-clear water passes through a filter with layers of sand, charcoal, and gravel. The filter takes out all but the tiniest pieces. The water is then sent to a clearwell, where ammonium sulfate, lime, and additional sodium hypochlorite are added. Finally, it is pumped into storage tanks until people need to use it. As it flows out to homes, factories, and businesses, caustic soda is added to control the water's acidity. This is an important step; if the water is too acidic, it may react with the metal surface of water pipes and pick up some of the metal. 7 In some coastal areas around the world, including California, desalinization plants are being built. These plants remove the salt from ocean water so that people can drink it. Salt can be removed by distillation or by reverse osmosis (pumping seawater at high pressure against a special membrane). Such plants can produce twenty-five million gallons of drinking water a day, but they are expensive to build and may harm the ocean. 8 Windhoek, the capital city of Namibia, is located between two deserts, so it has a constant water shortage. The city has developed a method so that waste water from the city's sewage-treatment plant can be reused. Advanced treatments remove ammonia and dissolved organic material. The water is purified by adding chlorine and lime. Normally, the reclaimed water irrigates parks and gardens, but during droughts, as much as thirty percent of the clean water pumped into homes comes from reclaimed water. Water shortages can be severe in some areas of the world, so we should continue working to find better methods of conserving and reusing our water supplies. Question 1 Which statement would be included in a summary of the passage? A Many people who live near aquifers get their water from wells.

What is the function of the cell membrane
A cell membrane protects a cell from it's surroundings. The cell membrane controls the movement of substances from the outside and inside of cells and organelles.
The cell membrane, also known as the plasma membrane, is the outer covering of animal cells which sits inside the cell wall of plant cells. It is semi-permeable so it allows certain materials to go in and out of the cell. Substances that can pass easily in and out of the cells include oxygen, carbon dioxide, and water. So basically, it is separates the cytoplasm from the outside environment, allowing only certain molecules to enter and exit the cell and also controls the amount of the substances that can go in and out.
