what is stimuli in biology in terms of igcse ????
Answer: A Stimulus is any change either internal or external which leads to a response. This could be a noise, smell or the changes in blood sugar level.
Explanation:
PLS HELP FAST!!!! You have a natural-gas (methane, CH4) stove. When you ignite a natural-gas stove, the methane reacts with oxygen (O2) to produce carbon dioxide and water vapor. Write a balanced equation for this reaction, and be sure to show your work. (6 points)
Answer:
Methane (CH4) ( C H 4 ) burns in oxygen to produce carbon dioxide and water vapor. The balanced equation is: CH4+2O2→CO2+2H2O C H 4 + 2 O 2 → C O 2 + 2 H 2 O .
Explanation:
The balanced equation for the reaction of methane with oxygen is CH₄ + 2O₂→CO₂ + 2H₂O.
What is methane?Methane is a gas and a chemical compound with formula CH₄. It is a colorless and odorless gas and very flammable. It is made up of carbon and hydrogen. Methane comes under greenhouse gas.
As it is highly reactive, it reacts with the gases present in the environment. Here, methane is reacting with oxygen. When one molecule of methane reacts with two molecules of oxygen, it produces carbon dioxide and two molecules of water.
The reaction happens in the presence of heat and high temperature. The balanced reaction is written when the same number of moles are present on both sides of the reaction.
CH₄ + 2O₂ → CO₂ + 2H₂O.
Thus, the balanced equation for the reaction CH₄ + 2O₂→CO₂ + 2H₂O CH₄ + 2O₂ → CO₂ + 2H₂O.

Hundreds of years ago, a volcanic eruption killed many plants and animals on a tropical island. Today, the island looks much as it did before the eruption. Why is this true? Destroyed ecosystems always return to their exact original state. Altered ecosystems only regain stability from the development of grasses. Geographic barriers prevent the migration of animals to island habitats. Destroyed environments can recover through ecological succession.
Answer:
Destroyed environments can recover through ecological succession.
Explanation:
Ecological succession describes a progressive change in the species in an ecological community over time.
This can happen after some disturbance such as a fire, earthquake, or volcanic eruption. It can mean that a e can return to the state it was before the event.
_______ species are the first species to colonies disturbed or newly created environment

gene is a segment of DNA on a chromosome. How are genes related to the proteins made by a cell?
Answer:
The DNA in genes is transcribed into RNA and translated into proteins
Explanation:
The sequence of DNA in a gene is transcribed into a messenger RNA (mRNA). This sequence of this mRNA is translated into a sequence of amino acids that form a protein.
The sequence of DNA in a gene directly affects the amino acids, and therefore the structure and function of, a protein.
Answer:
The structure of the genes in a cell determines the structure of the proteins made by the cell.

1. Scientific question: Can detergent affect flower growth?
2. IV: The soap used in the study
3. DV: Flower growth
Explanation:
A scientific question is a well-sustained question about a given phenomenon of the real world which can be answered by experimental and/or observational procedures. A good scientific question must be testable and lead to falsifiable hypotheses. The dependent variable is the variable that is being measured in the experiment, (i.e. it is being affected by the experimental procedure). On the other hand, the independent variable is the variable that isn't changed by the other variables that are being measured in the experiment.
How does the Golgi Body and Plasma membrane work together ?
Answer/Explanation:
The Golgi body is a system of flattened sacs that is involved in the packaging, modification, and transport of proteins. It is particularly important for proteins that have to be transported outside of the cell.
Proteins from the Golgi that are to leave the cell are transported in vesicles. When they reach the membrane, the vesicles fuse with it and release the proteins outside of the cell

Which of these chemicals is not a pollutant?
A. Methane
B. Nitrogen gas
C. Nitrate
D. Carbon dioxide
Answer:
All these chemicals are primary causes of pollution. Although, only one isn't an air pollutant. Which would make my best Guess C. Nitrate
Explanation:
A. Methane Is the main component in gas and oil. Oil companies have been responsible for polluting our air with about seven million tons of methane per year.
B. Nitrogen gas in general is one of the main air pollutions. otherwise know as Nitrogen dioxide.
C. Nitrates are found in ground waters and transfers into the soils surrounding said waters. Nitrates commonly are a cause of death in infants when drinking tab water or eating crops grown from nitrate infected soils. Adults aren't nearly as infected by this.
D. Carbon Dioxide is a greenhouse gas that pollutes our air and has been a main cause of global warming.
I'm at a loss for answering this question since all of these are polluting our earth in some way. The only way I can think to answer this is that all but one are air pollutants. So maybe the one that is not a air pollutant is the correct answer. My best guess is C. Nitrate
