Answer:
The shape of an enzyme determines which reaction it can catalyze.
Explanation:
Each enzyme is specific to one type of reaction. According to the structure of each enzyme, it has an active site capable of binding to a specific substrate, so the shape of the enzyme determines the type of reaction to be catalyzed.
Once the reaction occurs, the enzyme releases the product of the reaction and the enzyme is available for another reaction.
Regarding the other options:
- <em>The shape of an enzyme no depends on the reaction that it needs to catalyze.
</em>
- <em>Due to their specificity, enzymes can only catalyze one reaction at a time</em>
- <em>The shape of the enzyme is not altered after the reaction.</em>
Answer:
The second pair of grandparents have approximately 12 to 19 boys as grandchildren.
Explanation:
The probability of a grandchild being a girl or a boy is same, i.e.,
.
The first pair of grandparents have 4 grandchildren.
The second pair of grandparents have 32 grandchildren.
If first pair of grandparents have between 40% to 60% boys as grandchildren then the number of boys are in the limit,

Thus, the first pair of grandparents have approximately 2 to 3 boys as grandchildren.
If second pair of grandparents have between 40% to 60% boys as grandchildren then the number of boys are in the limit,

Thus, the second pair of grandparents have approximately 12 to 19 boys as grandchildren.
So, it is clear that the second pair of grandparents are more likely to have between 40% and 60% boys as grandchildren.
Also according to the law of large numbers as the sample size increases the probability of an event gets closer to the theoretical probability.
Easy,
1- Proteins gives us energy
2- Proteins help us in cell repair and they take part in cell reproduction
3- Proteins contain powerful particles that diffuses and give energy to do work
4- Proteins are powerful

Inside the limit of the earth is an accumulation of four related parts called "circles." Earth's circles include:
the lithosphere, which contains the majority of the icy, hard, strong shake of the planet's outside layer (surface), the hot semi-strong shake that lies underneath the hull, the hot fluid shake close to the focal point of the planet, and the strong iron center (focus) of the planet
the hydrosphere, which contains the greater part of the planet's strong, fluid, and vaporous water,
the biosphere, which contains the greater part of the planet's living life forms, and
the air, which contains the greater part of the planet's air.
These circles are firmly associated. For instance, many winged animals (biosphere) fly through the (air), while water (hydrosphere) regularly courses through the dirt (lithosphere). Truth be told, the circles are so firmly associated that an adjustment in one circle regularly brings about an adjustment in at least one of alternate circles. Such changes that happen inside a biological community are alluded to as occasions.

1. Landforms in the area - depends on the land formation how high or low is your location that climate might affect you.2.Latitude - distance from N or S pole3.Wind - depends on the movement of the air.4. Humidity - depends on the amount of water vapor in the air5. Elevation - depends the distance of of the location from sea level.

Meteorologists utilize a wide range of apparatuses for various purposes. A great many people know about thermometers, indicators, and anemometers for measuring temperature, pneumatic stress, and wind speed, separately. Meteorologists utilize different instruments, too. For instance, climate inflatables are extraordinary inflatables that have a climate pack on them that measures temperature, pneumatic stress, wind speed, and twist bearing in every one of the layers of the troposphere.
