How were redi’s and pasteur’s experiments similar
Answer:
Both tested the idea of spontaneous generation.
Explanation:
The Redi's and Pasteur's experiment was performed to disprove the theory of spontaneous generation. They proved that life come from the pre existing life by working on the maggots and condition that originates the maggots from the flies.
How do substances like CO2 and water move in and out of the cell?
(Please Answer) :)
｡☆✼★ ━━━━━━━━━━━━━━ ☾
There are three processes you need to know of:
Diffusion, Osmosis and Active Transport.
Liquids (such as water) move via osmosis.
Osmosis is literally the movement of particles across a partially permeable membrane from an area of high conc to an area of low conc.
CO2 would move via either diffusion or active transport.
Diffusion is the movement of particles across the concentration gradient (i.e from high conc to low conc)
Active transport is the movement of particles against the conc gradient (i.e from low conc to high conc)

How does a genotype differ from a phenotype?
The sum of an organism's observable characteristics is their phenotype. A key difference between phenotype and genotype is that, whilst genotype is inherited from an organism's parents, the phenotype is not. Whilst a phenotype is influenced the genotype, genotype does not equal phenotype.
Answer:
What is the difference between a genotype and a phenotype? A genotype refers to the genetic characteristics of an organism. A phenotype refers to the physical characteristics. For example, having blue eyes (an autosomal recessive trait) is a phenotype; lacking the gene for brown eyes is a genotype.

What are greenhouse gases
and how do they contribute
to global warming?
Answer:
they contribute to global warming because the greenhouse gases affect the ozone layer making it having holes which allow more sunlight to reach Earth surface which results to global warming
Explanation:
they contribute to global warming because the greenhouse gases affect the ozone layer making it having holes which allow more sunlight to reach Earth surface which results to global warming
Answer:
"Greenhouse effect" is the warming of the climate that results when the atmosphere traps heat radiation from Earth towards space. Certain gases in the atmosphere resemble glass in a greenhouse, allowing sunlight to pass into the "greenhouse," but block Earth's heat from escaping into space. These gases that contribute to the greenhouse effect include water vapor, carbon dioxide (CO2), methane, nitrous oxides, and chlorofluorocarbons (CFCs). Carbon dioxide is responsible for 53% of the of global warming. It is the result of processes of the use of products such as fuel deforestation and production of cement and other materials. Its permanence in the atmosphere varies, but it’s very high at all times since 80% lasts for 200 years and the other 20% can take up to 30,000 years to disappear. Methane is the next of the greenhouse gases which has the biggest effect on global warming with 15%. This is produced by activities such as livestock production, agriculture, sewage treatment, natural gas and oil distribution., coal mining, fuel use and is also given off from waste tips, and lasts an average of 12 years in the atmosphere.

Chemical mechanisms that can turn off or reduce an enzyme are _____.
a.) inhibitors
b.) activators
c.) centrioles
d.) vacuoles
Answer:
Explanation:
Chemical mechanisms that can turn off or reduce an enzyme are inhibitors. Explanation; -Enzyme inhibitors are molecules or compounds that bind to enzymes and result in a decrease in their activity. They can bind to an enzyme and stop a substrate from entering the enzyme's active site and/or prevent the enzyme from catalyzing a chemical reaction.
Answer:
Inhibitors
Explanation:
They inhibit enzymatic activity.
