The chemical reactions in the cell would not happen as fast and would require more energy to catalyze the reaction between the two reactants.

Chemistry/ Example: Take breathing for example, when you breath you breath out carbon dioxide. The CO2 can't just leave like that and only 10% binds to hemoglobin. The rest turns into carbonic acid in your blood and its plasma. However, the acid is unstable, so it turns into bicarbonate and a dissociated proton (H). You have carbonic anhydrase that converts the two so you can breath out CO2; the carbonic acid separates into H2O and CO2. This process would take a LONG time without the enzyme-- CO2 build up, even minimal amounts it lethal.
There a small amount of alcohol in celery and salt the two make a base particles that run that soaks up the food colouring
A person who exhibits a blood pressure of 134/82 mmhg would
likely have a pulse pressure of beats/min ranging from sixty to seventy beats
per minute in which a person would likely receive as a pulse pressure when he
or she has a bp of 135/82 mmhg
When we talk about meiosis I and II we talk about gametes formation.
The objective is to create cells with half DNA charge, called haploids.
At the meiosis I, in prophase I, crossing over happens and anaphase separated homologous chromosomes.
In the end, you still have cells with all DNA charges (2n).
To start meiosis II cells does not duplicate its DNA. When anaphase II happens sister chromatids split, and you end with half DNA charge cells. Haploids or (n).
28. A scientific theory explains an aspect of the natural world and can be tested repeatedly using the scientific method or experiments. This means that the explanations or content of a scientific theory is based on evidence gained through observation or experimentation.
The answer is True.
29. Scientific law is a statement that describes a a phenomenon that has been observed in repeated experiments. These statements are verified through the scientific method. Laws do not change; rather, they are applied to expand or broaden certain aspects.
30. Experiments are done to support, refute or validate existing theories. They show cause and effect insight through demonstration. These theories then may bring about laws in the scientific field.
The answer is then True.
31. I would get the Refrigerator A. The cost of running Refrigerator A is $10.00 a month, while B is $15.00 a month. This means the energy consumption is less with refrigerator A. Although B is cheaper, the energy consumption is much higher. In the long run, refrigerator A, would be a better investment.
32. Patterns of stars in the sky are called constellations. Constellations are a group of stars that form a recognizable pattern that is traditionally named after the mythological figure or whatever thing, animal or person that resembles the pattern.
The answer is B.
33. Ancient Greeks and Romans believed that the patterns in the sky represented mythological characters and animals. Examples of such would be Aries, Cancer, Capricornus, and the Big dipper. Romans mythology also depicts other celestial bodies as their gods, like mercury after the messenger god; Venus, the goddes of love and beauty.
The answer is C.
34. The sun in the solar system is a star. In fact, a star is considered or is called a sun if it is the center of a planetary system. Our own sun is the largest object that you can find in our solar system.
The answer is B.
35. The sun, is the closest star to Earth specifically. It is about 93 million miles away. It is brighter than the other stars because of its closeness. It makes up 99.8% of the total mass of our solar system.
The answer is B.
36. Light from the sun travels at the speed of light. It takes 8 minutes and 20 seconds for it to travel from the sun to the surface of the Earth at an average. It varies at times because the orbit of the Earth is elliptical.
The answer is A.
