Answer:

It causes global warming as well as air pollution.

Explanation:

Burning of fossil fuels has adverse effect on outdoor air pollution because when the fossil fuels burns carbondioxide gas is released in the atmosphere. Carbondioxide gas is a greenhouse gas which is released in the atmosphere through burning of fossil fuels and is responsible for increasing air pollution. This increase in carbondioxide gas leads to global warming due to blockage of solar radiation that is reflected from the earth surface.

Answer:

Fitness or aptitude

Explanation:

Aptitude (or fitness) is the genotype/phenotype that results in the survival, fertility, and capability of having a mate. It is a way of measuring the individual ability to leave fertile offspring.

Aptitude puts together everything that matters in natural selection. Includes the survival capability, finding a mate partner possibility, producing fertile descendants, and leaving the genes to the next generation. The aptitude of a genotype must be significant for natural selection to act in its favor.

Answer:

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.

Answer:

Enzyme activity depends on many factors such as Substrate concentration, enzyme cofactor, enzyme inhibitors, pH, and temperature. pH and temperature are two important factors that directly affect the activity of an enzyme as follows:

1. pH

Each enzyme has the specific optimal pH that allows it to perform its function to its fullest. The enzymes are the protein made up of the interaction of the hydrogen bond in the side chain of the protein. if there is any change from optimum pH, the enzyme activity decreases until it stops working.

2. Temperature:

Each enzyme has its own optimal temperature. Any modification or change in temperature results in the activity of an enzyme, and it also leads to the denaturation of an enzyme as it is made up of protein.

Answer:

Budding

Explanation:

The common asexual method of reproduction by hydras is budding. Buds originate at the junction of the stalk and gastric regions. The bud begins as a hemispherical outpouching that eventually elongates, becomes cylindrical, and develops tentacles. The bud then pinches off and a new individual becomes independent. Buds are produced every two to three days under favorable conditions. Following unfavorable conditions, such as injuries or periods of scarce resources, hydras occasionally reproduce through transverse and longitudinal fission.
