Answer:
The problem will be because:
The error in the construction of the bridge will be actually 40 cm.Explanation:
When you, as an engineer, listen about a scale 1/20, it means that for each 1 cm in the model, it will be 20 cm in the real footbridge (20 times upper to the scale model), then how the error in the model is 2 cm, the real error is 40 cm, in this case, imagine that you didn't know that the bridge will have an error of 40 cm, which is approximately 1,31 ft, from a side of the bridge you begin with the correct measure, and the other side you use the measure with the error of the 40 cm, the result is that when you going to finish the bridge in the center, this won't match, making more expenses to correct that big error.

Transpiration occurs when plants release water vapor.
True or False?
Answer:
true
Explanation:
Answer:
false Explanation: The water eventually is released to the atmosphere as vapor via the plant's stomata tiny, closeable, pore-like structures on the surfaces of leaves. overall this uptake of water at the roots, transport of water through plant issues, and releases of vapor by leaves is known as transpiration.
The distance that wind blows across an area of the sea to generate waves is the_________.
a)trough
b)wave period
c)fetch
d)sargassum
Answer: C-fetch
Explanation:
Answer:
Fetch.
Explanation:
Fetch, area of ocean or lake surface over which the wind blows in an essentially constant direction, thus generating waves. The term also is used as a synonym for fetch length, which is the horizontal distance over which wave-generating winds blow.

Explanation:
what causes rain to fall from the sky
Answer:
Rain is precipitation.
here’s the cycle:
1. Evaporation.
A body of water is evaporated by the heat of the sun. The water particles turn into vapor gas and move up as they are evaporated, and this leads to the next step.
2. Condensation.
The particles/molecules are collected inside of the clouds. They continue to collect until they’re ready for the next step.
3. Precipitation.
The droplets are now large enough to form rain, so they fall out from the clouds. This is precipitation.
And the cycle continues.
So that’s how rain is formed.
Hope this helps and please hit the thanks button and mark me brainliest if it did :)
Answer:
The water cycle
Explanation:

Answer:
The correct answer is C.Why do countries not convert from the use of oil to solar energy?
Solar energy is more difficult to use than oil to make electricity.
It requires more work to use solar energy to make electricity.
Solar energy is a limited resource.
It is more expensive to create solar energy than use oil for making electricity.
Answer:
It is more expensive to create solar energy than use oil for making electricity.
Explanation:
Solar energy is a renewable source of energy from the sun. It is the most powerful and eco-friendly source of energy, however, many countries still do not use this source of energy in creating electricity. This is because the technology behind using solar energy to create electricity is very expensive in comparison with the use of oil.
In as much as solar energy is always readily available everywhere and everyday (natural), building the technology to make it generate electricity is huge. Hence, countries stick to the use of oil, which is way cheaper to operate.
Which structure will form when a primitive cell engulfs an aerobic bacterium?
Answer:
Mitochondria

Answer:
Mitochondria
Explanation:
If plant sap has as much sugar as a can of soda, do you think that if you bit into a plant’s leaves or stems, would it taste sweet? Why or why not?
Answer:
No
Explanation:
If plant sap has as much sugar as a can of soda, they will not taste sweet if one bit into their stems of leaves.
This is because most plants do not store sugar, which is the product of photosynthesis, in leaves or stems. The few ones that store their photosynthetic products in leaves/stems do not store them directly as sweet sugar. They often stored them as starch which is not generally sweet in taste.
Hence, plant's leaves/stems will not taste sweet even if they have as much sugar as a can of soda.
When listing the levels of organization in organisms from least complex to most complex, which level is just below organs in complexity?
Answer:
D tissues
Explanation:
On April 20, 2010, an explosion on the Deepwater Horizon Macondo oil well drilling platform released 4 million barrels (636,000 cubic meters) of oil into the Gulf of Mexico. It took scientists and engineers nearly three months and several different attempts to cap the well. The Macondo oil well was located 1524 m (5000 feet) below the surface of the water, about 80 km (50 miles) off the coast of Louisiana. The spill affected 2113 km (1300 miles) of shoreline along the coasts of five states. Most crude oil contains 84–87% carbon by weight. Scientists have not yet fully assessed the environmental impact of the accident.

How do barnacles get nutrients?
O They catch small land insects.
O They attach themselves to seaweed and feed on it.
O They filter microscopic organisms from the waters.
O They crawl upon the ocean floor and feed on parasites.
Answer:
The answer is: They filter microscopic organisms from the waters.
Explanation:
Barnacles are filter feeders, which is why they are usually on dock poles and non-moving structures underwater. They do not need to travel to get food, because it comes to them!
Answer:
The answer would be that they filter microscopic organisms from the waters .

The ringing of a telephone prompts to answer a call.
Explanation:
The sensory neurons found in the receptor organ ( which is the ear ) will detect the ringing of the telephone, and will therefore transmit a nervous message to the central nervous system .The brain interprets the nervous message , and then sends a message through the motor neurons to the effector organ , which in turn will respond by answering the call .
