I think the best answer would be high. A chemical reaction can start when enough activation energy is added to the reactants. In living things the activation energy for chemical reactions is high. Because enzymes are present in cells in order to speed up reactions and give an alternative way for the reaction to occur.

High, the enzymes in cells function or speed up reactions by lowering the activation energy.

What are the 3 types of catalyst?
vagabundo [1.1K]
The three types of catalyst are positive, negative and auto-catalytic. <span>A positive catalyst increases the activation energy which decreases the rate or speed of the reaction. A negative catalyst decreases the activation energy which increases the rate or speed of thee reaction. An auto-catalyst starts slows and the reaction continues itself based on the products formed.</span>

A given hydrocarbon is converted completely to carbon dioxide and water, and equal numbers of moles of co2 and h2o are produced.
Sauron [17]
X moles of CO₂, and x moles of H₂O

CxH2x + 3x/2 O₂ -------> xCO₂ + xH₂O

CxH2x or CnH2n ----> ALKENE ( hydrocarbon with double bond)

Fossil originally has 254 g of carbon-14 but currently has 127 g of carbon-14 the fossil is most likely
KATRIN_1 [288]

Answer:

The answer to your question is: letter C) 5730

Explanation:

Data

Originally Carbon - 14   254 g

Currently Carbon - 14   127 g

Half-life of Carbon -14 is when half of the original amount of Carbon disintegrates.

Then, if originally there were 254 and now there are 127, only one half life passed.

Half life of carbon -14 is 5730 years old.

1. Compare and contrast active transport and passive transport. Include at least one similarity and one difference between the t
kolbaska11 [484]
Hello,

Your brainliest answer would be:

1A. Both involve ion movements

1B. Passive transport moves ions from high concentration to low, using no metabolic energy.



2A. Both passive transport processes.

2B. Diffusion refers to the movement of any chemical from one place to another, whereas osmosis exclusively from one place to another.

Plz mark me brainliest!

Hope this helps!
