Answer:

The Big Bang is an expansion event that occurred about 13.7 billion years ago

Explanation:

The Big Bang Theory is the leading explanation for how the universe began. Simply put, it says the universe as we know it started with an infinitely hot and dense single point that inflated and stretched — first at unimaginable speeds, and then at a more measurable rate — over the next 13.8 billion years to the still-expanding cosmos that we know today.

1.) What gives water all its properties? 2.) What type of bond joins H2O to another H2O and forms cohesion? 3.) What property of
Yuri [45]

Answer:

1. polarity

2. hydrogen bonding

3. High heat capacity

4. Adhesion

5. polarity

6. surface tension

7. high heat vaporization

8. hydrogen bonds form a rigid and stable network

9. Water is a polar substance and fat is a nonpolar substance.

10. Cohesion

Explanation:

Water is a polar molecule that is held together by hydrogen bonds to form strong cohesive forces. This accounts for the surface tension in water. Surface tension is the force acting on water that it makes to behave like a stretched elastic skin.

The polarity of water accounts for the fact that it is found in several parts of the body where it largely plays the role of a polar solvent.

High heat capacity of water enables it to function well in the area of thermoregulation in the body. High heat vaporization accounts for the fact that water helps maintain extreme temperature changes in an area.

When in solid state, the hydrogen bonded network in water becomes rigid and forms a very stable network of water molecules. Being polar, water does  not interact with fat because like dissolves like.

In plants, the attachment of water to plant roots is known as adhesion and is necessary for the capillary movement of nutrients to plants via the root.

One of the reasons bacteria can be so deadly is because they multiply very quickly. E. coli has a doubling time of around 15 min
Travka [436]

Answer:

The correct answer is - 25600 bacteria.

Explanation:

Bacteria can divide and produce double their population very quickly. As mentioned in the question bacteria multiply every 15 minutes to their double number. Finding the number of bacteria after 2 hours is simple mathematics. Two hours means 120 minutes and dividing it to 15. The result will be 8 which mean the bacteria double their colony 8 time so,

100×2 to the power 8 = 100 (initial number of bacteria)×2×2×2×2×2×2×2×2= 25600

Thus, the correct answer is option- 25600 bacteria.
