Astronomer Edwin Hubble classified galaxies<span> into four major types: spiral, barred spiral, elliptical and irregular. Most of the nearby, bright </span>galaxies<span> are spirals, barred spirals or ellipticals. Spiral </span>galaxies<span> have a bulge at the center and a flattened disk containing spiral arms.</span>
I found the attached image on the internet and it really helps complete this exercise.
First question:
In the presence of an enzyme, the course of the reaction is shown by the
red curve. The necessary energy to make a reaction occur is less when there is an enzyme to help the reaction happen. Enzymes work as catalysts that act over substrates converting them into different molecules in a much accelerated way then it would happen without the enzyme's help, if it would happen at all.
Second question:
The activation energy is represented by
line B. The activation energy is the energy needed to be available for a reaction to happen. If we compare it with line A, which represents the activation energy necessary for a reaction without an enzyme, we can see how much less energy is necessary to dispend when an enzyme is part of the reaction. Line C represents the energy resultant from the reaction.
Scientists collect ongoing data from many locations around the world. They then input this data into a mathematical or computer-based model to simulate real-world conditions.
<h3>What is climate forecasting?</h3>
Weather averages and other climatic characteristics are predicted by climate forecasts from a few weeks to a few years in advance. Such forecasts are increasingly being made using thorough models of the Earth's climate system.
Since it aids in forecasting future climate conditions, climatology and weather forecasting are crucial. The likelihood that snow and hail will reach the surface can be calculated using latitude. You may also determine the thermal energy from the sun that a location can get.

Answer:
The correct option is this: AN INCREASE IN FLUID TAKEN BY MOUTH WOULD REDUCE THE AMOUNT PRODUCED BY METABOLISM.
Explanation:
Generally, the amount of water consumed by a person normally leads to increase in the amount of urine that the person will excrete, that is, the higher the quantity of water consumed, the higher the quantity of the urine that will be excreted under normal circumstances. Thus, the statement given in option B is false. The statements given in Option C and D are right; during exercise the quantity of sweat produce and lost by the body is higher than the one that is produced when one is not exercising. Also, diarrhea usually lead to loss of water from the body.
