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.

Scientists took some cells and grew them in a Petri dish with nutrients. After a while, the cells grew to form a thin layer and stopped when they came in contact with other cells. What does this tell you about cells and the cell cycle?

Answers

Answer:

Contact inhibition.

Explanation:

Contact inhibition is a response of a cell in which cell growth stopped when it touches or comes in contact with another cell. When the normal and healthy cells grows and touching other cells, the cell receives a red light signal to stop its growth so the cell stop its growth while on the other hand, if there is no contact with other cell the cell continues its growth.


6. A pink snapdragon is crossed to a white snapdragon. What is the probability of getting a red snap dragon

Answers

A Possibility is 0%

In pea plants, tall (T) is dominant to short (t). A plant with genotype Tt is crossed with a plant with type tt. What percentage of their offspring will be tall?

Answers

Answer:

50%

Explanation:

Draw a Punnet square to determine the percentage of offspring that are tall.

The green and blue highlighted columns and rows represents the genotype of the parents. To fill in the genotype of the offspring, write down the letter (T/t) of the parent allele from that row and column the offspring belongs to. By convention, the T is written before t. (The genotype of a tall offspring is written as Tt not tT)

Since the T allele is dominant, as long as the offspring has one T, the offspring is tall. The t allele is recessive, thus two ts (tt) is needed for the short trait to be expressed.

From the Punnet square, the result is 2 offsprings that are tall and 2 offsprings that are short.

Required percentage

[tex] = \frac{2}{4} \times 100\% \\ = \frac{1}{2} \times 100\% \\ = 50\%[/tex]

which characteristic of living organisms is responsible for the production of oxygen in the leaf of a plant exposed to sunlight.

Answers

Answer:

Photosynthesis.

Explanation:

Photosynthesis is a characteristic of living organisms and it is typically responsible for the production of oxygen in the leaf of a plant exposed to sunlight. It is a chemical process used by plants to obtain food from sunlight.

All living organisms such as plants and animals require energy to function properly (life activities). Thus, the cell organelle where energy from nutrients is released is generally referred to as mitochondria. Animals and plants retrieve energy using mitochondria to do cellular respiration because they typically act like a digestive system by taking in nutrients, breaking them down and obtaining energy rich molecules for cell-life activities.

Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.

Is mixing sand a gravel a physical or chemical change?

Answers

Answer:

I believe it's a physical change?

Explanation:

Mixing sand and gravel is considered a physical change as it only affects the physical properties, such as appearance and distribution, without altering the chemical nature of the substances involved.

A physical change is a transformation that does not alter the chemical composition or identity of a substance. In the case of mixing sand and gravel, both substances retain their individual properties and characteristics even when they are combined.

The sand particles and gravel particles remain unchanged in terms of their chemical composition.

The mixing process involves the physical interaction of sand and gravel particles, resulting in a uniform distribution of the two components. This change in arrangement does not involve any chemical reactions or the formation of new substances.

The sand and gravel can be easily separated by physical means, such as filtration or sieving, without undergoing any chemical transformations.

Therefore, mixing sand and gravel is considered a physical change as it only affects the physical properties, such as appearance and distribution, without altering the chemical nature of the substances involved.

Answers

I believe it’s O Meiosis

The process that produces gametes in animals is meiosis.

What is Meiosis

Meiosis is a specialized type of cell division that occurs in the reproductive cells, or germ cells, of animals. It involves two rounds of cell division, resulting in the production of four haploid daughter cells, each with half the number of chromosomes as the parent cell.

During meiosis, the genetic material is shuffled and recombined through processes such as crossing over and independent assortment. This genetic variation contributes to the diversity of offspring produced through sexual reproduction.
