how many layers are in earth atmosphere ?

The Earth’s atmosphere is layered and each layer of the atmosphere has its own specific traits. The atmosphere of Earth is divided into four layers as Troposphere, Stratosphere, Mesosphere and Thermosphere

Generally, temperatures decrease with increasing height because the atmosphere distributes itself according to gravity. In the troposphere, the temperature generally decreases with altitude. The reason is the troposphere's gases absorb very little of the incoming solar radiation.

Troposphere - temperature decreases with altitude

Mesosphere - temperature decreases with altitude

The temperature increases with increasing altitude in the stratosphere because there’s a high concentration of ozone molecules.

Stratosphere - temperature increases with altitude

Thermosphere - temperature increases with altitude

Answer:

Increases the concentration of carbondioxide gas in the atmosphere.

Explanation:

The burning of fossil fuel increases the concentration of carbondioxide gas in the atmosphere because when the fossil fuel burns, carbondioxide gas is released. Carbondioxide gas is a greenhouse gas which goes up in the atmosphere and make a layer which allow light radiation to the earth but prevent it from going to the space after reflection which causes increase of surface temperature of the earth leads to global warming.

The fossil fuel combustion has increased the concentration of carbon atoms in the atmosphere.

Concentration of carbon means the amount of carbon in the atmosphere.

The amount of carbon dioxide has increased substantially after the industrial era.

The concentration of carbon is 400 parts per million in more traffic areas.

The level of indoor carbon depends upon the number of person present there.

Thus, the fossil fuel combustion has increased the concentration of carbon atoms in the atmosphere.

Answer:   1 Lysosomes and peroxisomes, Microtubules, Endoplasmic reticulum, Mitochondria

2 The role of the nucleus of a eukaryotic cell is to control the cell. Because it contains most of the cell's DNA, which is encoded with genetic instructions, the nucleus controls which proteins the cell makes.

3 The rough endoplasmic reticulum has ribosomes on its surface. This is what give the RER a "rough" appearance.            The smooth endoplasmic reticulum (SER) does not contain ribosomes. The Smooth ER looks more like tubes. The SER helps in the storage of proteins and lipids.

4 Secretory vesicles contain materials that are to be excreted from the cell, such as wastes or hormones.

Transport vesicles move molecules within the cells.

Pumpkin plants need a lot of sun. Choose the sunniest place you have; remember that pumpkins are sensitive and will need shelter from wind and frost. Try to protect pumpkins from the worst of the elements by covering them during heavy rains, or putting up some kind of barrier to protect the vines from high winds or using shade tents during summer’s hottest days.

Pumpkins like and need a lot of water, but don't plant pumpkins in wet or dense soil. They need good, well-drained soil. You can dig it up by hand. Don’t use a tractor, pumpkin roots don’t go down very far. Prepare the soil in early spring, as soon as the ground is warm. Fertilize the patch with a good four inches of rotting cow manure. Pumpkins do best in soil that is slightly acid or nearly neutral.

If you live in a part of the country where there is still danger of frost in late April or early May, start pumpkin seeds indoors about two weeks before planting. Sow one seed for every four-inch peat pot filled with grow mix. Keep the pots watered, never let them dry out.

How to Plant Pumpkins

When seedlings have the fourth or fifth leaf, set them outdoors in hills about the size of a pitcher s mound, one plant to a hill. Protect pumpkin seedlings the first few weeks with plastic-covered frames. Space each hill at least 20 feet apart.

How to Fertilize Pumpkin Plants

Pumpkin plants have two kinds of flowers, male and female, which appear in early July. The male flowers show up first, followed by the females. Look out for the first female flowers. Look for vines to be strong and well-established before letting a female flower set fruit. It might help to break off the first female on each vine and wait for the second or third, when the vines are at least ten feet long. A female is easy to recognize: she has a baby pumpkin at the base of each flower.

You need a big vine to produce a big pumpkin, so in a sense you’re choosing the vine before the pumpkin. When you find a vine that’s strong enough and a female flower on the verge of opening, put a bag of cheesecloth over it for the night to keep the insects out. The next morning pick a fresh male bloom, trim off the corolla or outer petals, and rub the pollen-laden stamen in around the center of the newly opened female bloom.

How to Grow Pumpkins

Giant pumpkinsThis is just the beginning of a summer of long but rewarding work. What you have started is actually a pumpkin-producing factory. Remember that there are 100 or more leaves to each vine and if you are trying to grow a 300-pound pumpkin, each leaf is responsible for up to four pounds of weight in your pumpkin. Every leaf, every stem, every hair roots is now receiving sunlight, absorbing water, and blending nutrients. All are traveling down the all-important stem to your prize pumpkin.

Giant pumpkins balloon out from the vine and if precautions are not taken, they will tear away and lose touch with their all-important stem. Since vines put out roots at every leaf, tear out the roots of the vine where it is close to the pumpkin. This will give it free room to grow without damage to the vine. Gently train vines away from the pumpkin to prevent it from crushing them, try giving them a nudge in the right direction every day.

When two or three fruits on each plant reach the size of softballs, remove all but the most promising one and start to prune the pumpkin plants. After the primary vine has reached 20 feet, pinch off the tips and the side shoots so the vines won't divert resource from the fruit. Break off all the other female flowers A potential prizewinner is forming. The work of the plant now must go entirely toward nurturing this fruit alone.

It is important to remember that the only thing that will increase the size of the fruit comes out of the vines and the vines must get support from the natural root. For growing really big pumpkins, the most important things to remember are seeds, soil, sunshine, and water.

By mid-August the plants are pulling in water and nutrients at a great rate. Nighttime is when pumpkins do their growing, most expand two inches in circumference every night.

If it’s a dry season, give each plant 15 to 20 gallons of water twice a week. Water in the evening, and water only the base of the plant to keep the leaves dry, which reduces the risk of disease.

The "Dill's Atlantic Giant" seed will produce a pumpkin that typically grows to reach between 200 and 300 pounds. They are not used for eating instead are carved and decorated.

Long sunlight hours are preferred by pumpkins, so choose your garden location accordingly. Select a location with sufficient surface drainage and stay away from shaded regions. Additionally, being close to a water supply is crucial because these pumpkins need a lot of water to grow to their full potential.

Monster pumpkin seeds should germinate in soil that is 70 to 90 degrees Fahrenheit and 65 to 75 degrees in the air. Plant pumpkins from seeds indoors and transplant the seedlings to your garden five to seven weeks later. After the final frost in late May, plant. Avoid locations with complete or partial shade because full sun is crucial.

Therefore, its important to grow giant pumpkins used for ornamental purpose.

It is also known as retinol because it produces the pigments in the retina of the eye. Vitamin A promotes good eyesight, especially in low light. Vitamin A (retinol) is ingested as either retinyl esters or carotenoids and metabolized to active compounds such as 11-cis-retinal, which is important for vision, and all-trans-retinoic acid, which is the primary mediator of biological actions of vitamin A

Explanation:

A good example would be a ball rolling along a flat surface. Since the ball is circular it will roll for a while but will stop after some distance. The force that caused this ball to stop is called friction. There are other things like air resistence but that is still considered friction. If you don't understand anything, please don't hesitate to ask.

For Example the net force for the box of frozen burritos would be zero if the rightward force was 45 Newtons and the leftward force was 45 Newtons. If the burrito box started moving at a constant speed before the forces were applied, it would either continue to move or remain at rest. If it was already at rest before the forces were applied, it would remain at rest.

The statement that best explains how a light wave behaves when moving from air to water is "it slows down and continues straight." That is the last option, i.e., option D, as light travels more slowly in water.

Waves react differently in different mediums, such as when the phenomenon of refraction is used in many optical devices such as lenses, prisms, and mirrors, and these devices change the property of light to slow down and bend when moving from one medium to another. In microscopes and telescopes, the study of light refraction has provided important insights.

Answer:

No, they do not all cause a change in amino acid sequence of a protein.

Explanation:

Substitution mutation is the type of mutation that results when the nucleotide base of a gene is replaced by another base in the sequence. A substitution mutation can result into three different types of mutation namely; silent mutation, missense mutation, and nonsense mutation.

- In silent mutation, the nucleotide base that gets replaced by another still forms a codon that encodes the same amino acid as in the original sequence. e.g if guanine replaces adenine in the sequence, TTA to form a mutated sequence, TTG. This mutated codon (TTG) still encodes LEUCINE amino acid just as TTA does. Hence, there is no effect on the resulting amino acid sequence. This portrays that NOT ALL SUBSTITUTIONS cause a change in amino acid sequence of a protein.
