The updrafts and downdrafts represented within this cloud are primarily caused by differences in?
A.altitude above sea level
B.air density
C.relative humidity
D.specific heat
Answer:
B.air density
Explanation:
Updraft and downdraft is the upward and downward movement of air.
It caused by differences in air densities. There could be differences in air current due to the heat that occur in the ground during the day time which makes air above more warmer than the air below. The air above is less dense as it rises above it becomes cool.
It also occur when air current moves over mountains.

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.
Do living organisms depend on each to survive?Why or why not
Answer:
Yes (very true)
Explanation:
All living organisms depend on each other to survive, whether be a small bacteria or something as large as blue whales. Living organisms depend on each other and on their environments, or habitats, to meet their needs for survival. For example there's this concept called symbiosis, which explains the relationship between two organisms or more where both benefit most of the time from the association. For example, some plants and fungi have symbiotic relationship where plants provide food for fungi (such as carbohydrates) and in return, fungi colonize the roots of plants and provide extra absorption of nutrient and water.

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 .
Describe a sperm cell. How does each structure contribute to the sperm's function? please this should be at least 150 words, I will be MARKING as BRIANILIST , please don't copy from Google, thank you so much.
Answer:
A sperm is a gamete male or a sex cell. It joins with the female gamete, called an ovule, to create a zygote. The process of formation is called fertilization.There are two parts to the sperm cell, the head and the tail. The arrangement of the sperm makes it ideally built for the efficiency of its purpose. The tail of the sperm helps give it the momentum it needs to reach the egg cell, so that the embryo can be created first. The sperm develops a tail and sheds the excess cytoplasm of the shaft. When the sperm is full, the tail will spin like a propeller such that the sperm will move itself forward. Mitochondria in the linking component generates the energy ( ATP) required to travel.The sperm cell is made up of the head, body (mid-section) and tail. Each of these parts is equipped with different molecules and a smaller structure that enables the sperm to function properly as a whole. Mature sperm cell (sperm cells) is 0.05 milliliters wide. It's made up of the head, body and tail. The head is covered by the ac-cap and contains a dense genetic material nucleus of the 23 chromosomes.
hope this helped!
Answer:
A sperm cell is the male reproductive sex cell. Sperm cells of different animal species have different shapes and structures. In humans it consists of two major parts, the head and the tail. The head is flat and almond-shaped. The head contains the nucleus which carries genetic substances called chromosomes. One sperm cell contains half the number of chromosomes the species has. Humans have 46 chromosomes so each sperm cell has 23. The sperm cells also carry the X or Y chromosome that determines the sex of the future child.
The tail of the sperm, sometimes called the flagellum, is a slender, hairlike bundle of filaments that connects to the head. It whips and undulates so that the cell can travel to the egg. Following sperm deposition in the female reproductive tract, activation of tail movement is suppressed until the sperm is carried to within a relatively short distance of the egg. This gives the sperm an increased chance of reaching the egg before exhausting its energy supplies.

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.

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.

Imagine you are an engineer who needs to test a scale model of a
footbridge. It will be a 1/20 scale model. The footbridge will cross
over a busy road and allow people to cross the road safely. How
could a relatively small design error of 2 centimeters in the model
system cause a significant problem in construction of the bridge?
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.
