Matter can change from one state to another if heated or cooled. If ice (a solid) is heated it changes to water (a liquid). This

change is called MELTING. If water is heated, it changes to steam (a gas).

This question is incomplete, here is the complete question:

Muscle contraction depends on ATP hydrolysis. During periods of intense exercise, muscle cells rely on the ATP supplied by three metabolic pathways: glycolysis, mitochondrial respiration, and the phosphagen system. Figure 1 shows the rates at which the three metabolic pathways produce ATP following the start of an intense period of exercise.

Which of the following correctly uses the data to justify the claim that the phosphagen system is an immediate, short-term source of ATP for muscle cells?

The right option that correctly uses data to justify the claim that the phosphagen system is an immediate, short term source of ATP for muscle cells is the figure that indicates that ATP PRODUCTION BY THE PHOSPHAGEM SYSTEM INCREASES AND DECREASES RAPIDLY FOLLOWING THE START OF THE EXERCISE PERIOD.

The phosphagem system are systems of energy storing compounds that are located in the muscles and in the nervous systems of living organisms. The biochemical compounds that made up the phosphagem system are ATP, ADP and creatine phosphates (CP). These three compounds undergo continuous changes in a pathway called ATP - CP pathway.

ATP and CP serve as intermediate reserves of energy for the body. The phosphagem system is especially important in living organisms because its serves as a ready source of energy for muscles and nerves, which regularly experience energy changes.

The phospagem system is very important when it comes to physical exercise, because it is the fastest mean by which the muscles get the energy (ATP) they need. In the beginning of exercise, there is always rapid fluctuations in the production of ATP as the phosphagem system produces ready energy for the exercising muscles. Energy from the phosphagem system can only be used for maximum of 10 seconds, thus, it is most important in exercises that requires instant burst of energy for a short period. The system works under anaerobic condition and last only for a few seconds.

You are the director of the Soil and Water District Management Team. Recently, tests have shown a decrease in crop yield as well

Dmitrij [34]

Answer:

Best three management practices would be: Stream side Buffers, Cover Crops, Nutrient Management Plans.

Explanation:

Conservation and management practices must be taught to every farmers for the deduction of chemical effect and nutrition erosion activities.
Areas bordering stream banks that are taken out of crop production or pasture use and planted with native trees, shrubs, or grasses, helps in managing the decrease in soil fertility and an increase in chemical runoff into the waterways. This technique is called as the stream side buffers.
To reduce runoff and erosion and enrich the soil with organic matter, cover crops must be planted. These crops soaks all the excess chemical fertilizers left on the field.

luda_lava [24]

Harriet Beecher Stowe's novel Uncle Tom's Cabin was a book that worked to expose northerners to the evils of slavery. Harriet Beecher Stowe sought to write a book that would expose the horrors of slavery and to expose the injustices that were taking place in the American South that Northerners might not have been fully informed about at the time. The book was certainly not hailed as a marvelous work in the South and was instead decried and bashed because it sought to expose the practices employed in the South's use of slave labor.

Explain the life cycle of frog in detail

nikklg [1K]

Answer:

The first stage is the egg stage. Eggs are usually laid in or near water. A frog can lay thousands of eggs at once. The eggs are laid in large groups. There are covered in jelly which makes them slippery. The jelly protects them from other animals eating the eggs.

The second stage is the tadpole stage. A tadpole hatches from the egg. The tadpole breathes using gills and moves like a fish. It uses its long tail to swim. Tadpoles eat tiny water plants.

The third stage is the froglet stage. It grows lungs and legs. Its gills disappear. Its tail gets shorter until it disappears too. The froglet swims to the top of the water to breath.

The last stage is the adult stage. A frog can leave the water now and live on land. It eats insects, worms and snails. Mother frogs return to the water to lay eggs. the air.
