What can make the shoots of seedlings on the window sill bend toward the window would be the production of hormones in response to light stimulus.
What is Phototropism?It is the movement of organisms in response to light. It can be of two types:
Positive phototropism when the organism moves toward light.Negative phototropism when the organism moves away from light.Plants are generally positively phototropic. The light stimulus stimulates the production of a hormone whose activities cause the plant to bend towards the light source.

what are coliform and why do they matter
Answer:
Coliform bacteria are organisms that are present in the environment and in the feces of all warm-blooded animals and humans. Coliform bacteria will not likely cause illness. However, their presence in drinking water indicates that disease-causing organisms (pathogens) could be in the water system.
Explanation:
The following chemical equation shows the reaction of cellular respiration.
C6H12O6+ __O2 —> 6CO2 + 6H2O + Energy (chemical)
Part A Balance the above reaction by writing in the correct coefficient.
Answer:
C6H12O6+ 6O2 → 6CO2 + 6H2O + Energy (chemical)
Explanation:
Given that,
→ C6H12O6+ __O2 → 6CO2 + 6H2O + Energy (chemical)
Now we have to balance the equation,
→ C6H12O6+ 6O2 → 6CO2 + 6H2O + Energy (chemical)
Hence, this is the balanced equation.
Where does the second, major part of cellular respiration take place

Explanation:
In the past few years, several bills that deal with noise pollution have been introduced in Congress. Several lawmakers want to make stricter laws at the national level to restrict noise pollution.
Compose a letter to one of your state's representatives about noise pollution. In your letter, persuade your lawmaker that noise pollution should be controlled more strictly and be sure to address the following points:
explain what noise pollution is and where it comes from,
explain how noise pollution can harm people,
explain how noise pollution can harm wildlife, and
explain how you think national noise pollution laws could work.
Answer:
1.Noise pollution, also known as environmental noise or sound pollution, is the propagation of noise with ranging impacts on the activity of human or animal life, most of them harmful to a degree. The source of outdoor noise worldwide is mainly caused by machines, transport, and propagation systems.
2.Noise pollution impacts millions of people on a daily basis. The most common health problem it causes is Noise Induced Hearing Loss (NIHL). Exposure to loud noise can also cause high blood pressure, heart disease, sleep disturbances, and stress. These health problems can affect all age groups, especially children
3.Studies have shown that loud noise can cause caterpillars' hearts to beat faster and bluebirds to have fewer chicks. Noise pollution makes it difficult for animals to use sound for navigation, finding food, mating, and avoiding predators, affecting many animals' ability to survive
4.We can Reduce Noise pollution by turning off appliances when not in use, use of earplugs, lowering the volume, planting more trees, regular maintenance of vehicles and machines. By controlling noise we can control negative health effects that noise pollution has on everyone.

What part of the visible spectrum is absorbed by the primary pigments of eukaryotic photosynthesis
Chlorophyll a absorbs wavelengths from either end of the visible spectrum (blue and red), but not from green. Because green is reflected, chlorophyll appears green. Other pigment types include chlorophyll band the carotenoids.
What do Primary pigments absorb?There are three primary pigments. Each pigment is designed to absorb a single primary color of light. Cyan pigments absorb red light and reflect blue and green light. Magenta pigments absorb green light and reflect red and blue light.
Thus, Chlorophyll a absorbs wavelengths from either end of the visible spectrum (blue and red), but not from green.

Osmosis, simple diffusion, and
facilitated diffusion are all examples
of.....
A. passive transport
B. active transport
C. energy assisted transport
Answer:
A
Explanation:
It's passive transport because it does not require energy, i.e. you don't need to invest ATP to make it happen. Osmosis is the movement of water from area of higher solute concentration to area of lower solute concentration. It happens via channel proteins called aquaporines. Simple diffusion is when gases like O2 or CO2 difuse through the cell membrane. Again, they go from area of higher concentration to area of lower concentration. Facilitated difusion is how large and polar molecules go in and out of the cell. This happens via transmembrane proteins down the concentration gradient (from higher to lower concentration).

how difference in the concentration of substances and temperature affect the shelf life of fruits and vegetables
The difference in the concentration of substances and temperature affect the shelf life of fruits and vegetables by increasing their intrinsic decomposition.
What is plant decomposition?The expression plant decomposition makes reference to a natural process where the plant parts can lose their properties.
The time of decomposition and/or putrefaction depends on environmental factors such as room temperature and internal factors such as ethylene concentration.
In conclusion, the difference in the concentration of substances and temperature affect the shelf life of fruits and vegetables by increasing their intrinsic decomposition.

Relying on the knowledge that you have gained from the lessons, explain what types of waste we must remove from our bodies. Why is waste removal required for all organisms?
Answer: Excretion is the removal from the body of waste products which result from normal life processes. Waste products such as carbon dioxide must be removed. If they are allowed to accumulate they cause poisoning which slows down vital chemical reactions.
