describe the water cycle process starting from an afternoon thunderstorm.

Answers

Answer:

Most thunderstorms form by a cycle that has three stages: the cumulus stage, mature stage, and dissipating stage.

Cumulus Stage

The sun heats the Earth's surface during the day. The heat on the surface and warms the air around it. Since warm air is lighter than cool air, it starts to rise (known as an updraft). If the air is moist, then the warm air condenses into a cumulus cloud. The cloud will continue to grow as long as warm air below it continues to rise.

Mature Stage

When the cumulus cloud becomes very large, the water in it becomes large and heavy. Raindrops start to fall through the cloud when the rising air can no longer hold them up. Meanwhile, cool dry air starts to enter the cloud. Because cool air is heavier than warm air, it starts to descend in the cloud (known as a downdraft). The downdraft pulls the heavy water downward, making rain.

This cloud has become a cumulonimbus cloud because it has an updraft, a downdraft, and rain. Thunder and lightning start to occur, as well as heavy rain. The cumulonimbus is now a thunderstorm cell.

Dissipating Stage

After about 30 minutes, the thunderstorm begins to dissipate. This occurs when the downdrafts in the cloud begins to dominate over the updraft. Since warm moist air can no longer rise, cloud droplets can no longer form. The storm dies out with light rain as the cloud disappears from bottom to top.

The whole process takes about one hour for an ordinary thunderstorm. Supercell thunderstorms are much larger, more powerful, and last for several hours.

C. Gases have particles that are closer together than thoes in a solid
D. Gases partical have less energy than solid paeticals.​

Answers

Answer:

B: Gases dont have fixed shape, solids do

Explanation:

A is false because gases and solids can be both made up of atoms and also molecules

B is true because gases do not have definite shape or volume, while solids have definite shape and volume

C is false because particles of a gas are farther apart under similar pressure, volume and temperature as particles of a solid

D is false because gases have more energy than solid particles under similar pressure, volume and temperature due to their movement they are constantly transfering energy from one particle to another as they move

Which type of reproduction is responsible for genetic variation?

Answers

Answer:

sexual reproduction

Explanation:

Sexual reproduction results in infinite possibilities of genetic variation. In other words, sexual reproduction results in offspring that are genetically unique. They differ from both parents and also from each other.

Other reproductions like asexual, budding or fragmentation don't produce genetic variation.

The type of reproduction is responsible for genetic variation is - sexual reproduction.

Sexual reproduction is combining genetic information from two individuals,  by the fusion of gametes such as sperm and egg, called fertilization which generates more genetic variation, by the process like the combination of alleles and crossing over.

Parents and offsprings are not identical in this reproduction type, however, they are genetically similar.Fusion or combination of two different parent's gametes.There is recombination take place which causes genetic variations as well.

Thus, the correct answer that is responsible for genetic variation is - sexual reproduction.

3.1 x 10-3 m
O 2.0 x 10-2 m
2.0 x 10-3 m

Answers

Answer:

B. 3.12 x [tex]10^{-3}[/tex] m

Explanation:

From the given picture, it can be deduced that;

the diameter of the image of lumen = 25.0 mm

                                                      = 25.0 ÷ 1000

                                                      = 0.025 m

And,

magnification = [tex]\frac{diameter of the image of lumen}{actual diameter of lumen}[/tex]

But magnification = 8,and diameter of the image of lumen = 0.025 m.

So that;

8 = [tex]\frac{0.025}{actual diameter of lumen}[/tex]

⇒ actual diameter of lumen = [tex]\frac{0.025}{8}[/tex]

                         = 0.003125

Actual diameter of lumen of the blood vessel is 3.12 x [tex]10^{-3}[/tex] m.

Iron rich deposits that formed about 2 billion years ago have red layers. Layers formed before then were not red. The red layers formed when oxygen made during photosynthesis reacted with iron molecules in the ocean. The oxidized iron formed layers of sedimentary rock

C. The atmosphere change the biosphere.
D. The biosphere change the lithosphere

Answers

Answer:

D. The biosphere change the lithosphere

Explanation:

The red formed due to oxygen which is produced by plants in the process of photosynthesis. This oxygen then reacted with iron atom and formed oxidized iron layers of sedimentary rock. So here plants are responsible for the formation of these layers and we considered plants as part of biosphere so we can say that biosphere is responsible for the change of lithosphere.

Bunnies and coyotes. For just one level of movement on the pyramid (bunnies to coyotes - their preferred food), and the bunny weighed 5 kg, how many kg of "energy" would the coyote actually get by eating it?

Answers

Answer:

The coyote is actually getting 0.5 kg of "energy" by eating 5 kg of bunnies.

Explanation:

At each trophic level, it occurs an energy transfer from one level to the next, with only 10% being usable in each of them. This assessment is called "The 10% rule". This is, as a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time. According to the 10% rule, to support 1 kg of coyote, 10 kg of the anterior level is needed. To calculate this, we need to multiply the biomass of the coyote by 10 to get the biomass of its anterior level.

If 10 kg of the anterior level (bunnies) are needed to support 1 kg of coyote, we need to calculate how many kgs of a coyote are supported by 5 kg of bunnies.

10 kg of bunnies ------- 1 kg of coyote

5 kg of bunnies --------- X =  0.5 kg of coyote.

Answer:

The coyote is actually getting 0.5 kg of "energy" by eating 5 kg of bunnies

Answers

Answer:

Explanation:

Exercise increases the temperature of body because about 20% of the energy produced in contracting muscles is used for muscle contraction while the remaining 80% is converted into heat energy, as a result body's temperature increases whereas a person who has infection also experience high body temperature because the body work faster to fight against the infection that leads to high temperature.

What is respiration ?

Respiration is a metabolic process in which an organism's living cells use oxygen to obtain energy (in the form of ATP) and release carbon dioxide as a byproduct of the oxidation of complex organic substances.

Anaerobic respiration occurs when there is no oxygen present, whereas aerobic respiration occurs when there is oxygen. Alcohol is produced by anaerobic respiration, whereas carbon dioxide and water are the byproducts of aerobic respiration. Compared to anaerobic respiration, aerobic respiration produces more energy.

Thus, respiration is a vital process of the body.

In the laboratory, yeast cells are usually grown at a temperature of 25oC. A scientist wanted to determine if yeast cells would reproduce faster or slower when the temperature was dropped to 15oC. The same number of yeast cells were placed in the same medium with the same amount of nutrients. One sample was kept at 25oC and the other one was kept at 15oC. The number of yeast cells was counted every hour for an eighteen hour period.

Answers

Answer:

This question is incomplete, however, it is asking to identify the following variables:

Independent variable: Temperature

Dependent variable: Number of yeast cells

Constants: same amount of nutrients, same number of yeast cells, same medium

Explanation:

- Independent variable is the variable that the experimenter changes or manipulates in order to bring about a measurable effect. In this experiment, the TEMPERATURE at which the yeast are kept is the independent variable.

- Dependent variable is the variable that responds to the changes made to the independent variable. It is the variable that is measured by the experimenter in the experiment. In this case, The NUMBER OF YEAST CELLS was counted, hence, it is the dependent variable.

- Constants are variables that are kept unchanged or same for all groups by the experimenter in order not to influence the experiment's outcome. In this case, the CONSTANTS are: same amount of nutrients, same number of yeast cells, same medium etc.
