The pressure on the disc attributed to body weight for a 1000 N man is 120000 N/m²
Formula for pressureP = F / A
Where
P is the pressureF is the forceA is the area Data obtained from the questionThe following data were obtained from the question:
Area (A) = 25 cm² = 25 × 0.0001 = 0.0025 m²Weight = 1000 NForce (F) = 30% of weight = 30% × 1000 = 300 NPressure (P) =?How to determine the pressureThe pressure can be obtained as follow:
P = F / A
P = 300 / 0.0025
P = 120000 N/m²
Thus, the pressure on the disc is 120000 N/m²

Three disadvantages of cloning.
Cloned animals might not live as long as animals that are not clones.Cloning is a complex and expensive process.Cloning can result in a reduction in genetic diversity, which can make a population more susceptible to diseases and environmental changes.What is the process of cloning?The process of cloning is described as follows:
A nucleus and an egg cell come from a body cell of animal A with its nucleus removed comes from animal B.
An enucleated egg cell from animal B is taken and the nucleus is removed.
The nucleus with DNA from animal A is placed in the enucleated egg cell from animal B.
The cell from animal A with its DNA develops into an embryo.
The embryo develops into a baby animal that is a clone of animal A.

A galaxy is a massive gravitational star system. They contain stars and their remains. Planets and other celestial bodies can orbit the stars. Between the stars is an interstellar substance containing gas, cosmic dust, and cosmic radiation, the denser regions of which are interstellar clouds. In addition, galaxies contain large amounts of dark matter, the nature of which is unknown.
Whereas for a long time the number of galaxies in the visible universe was long estimated at 200 billion, the number of galaxies is estimated to be at least 2 trillion based on recent observations.

in each case , state and explain the effect on fermentation of raising the temperature from 20 degrees to 45 degrees
Answers
Beyond certain thresholds, the heat can denature enzymes, kill yeast cells, and produce undesirable flavors. It is essential to maintain an optimal temperature range specific to the type of fermentation and the microorganisms involved to ensure successful and high-quality fermentation outcomes
Raising the temperature from 20 degrees Celsius to 45 degrees Celsius would have the following effects on fermentation:
1. Increased fermentation rate: The rate of fermentation is typically temperature-dependent. Increasing the temperature from 20 to 45 degrees Celsius would accelerate the metabolic reactions involved in fermentation. This would result in an increase in the rate at which sugars are converted into alcohol or acids, depending on the type of fermentation.
2. Accelerated yeast activity: Fermentation is often carried out by yeast, and yeast activity is highly influenced by temperature. Increasing the temperature to 45 degrees Celsius would speed up the metabolic processes within the yeast cells, leading to increased yeast activity and faster fermentation.
3. Shortened fermentation time: Due to the increased fermentation rate and accelerated yeast activity, the overall fermentation process would be shortened. The higher temperature would promote faster consumption of sugars and production of desired fermentation products.

september would the earth be experiencing a solstice or an equinox
how do you know
Answers
In September the earth will be experiencing an equinox
Equinoxes occur between March and September. When the Sun's rays strike the equator at midday and at a 90° angle, it is considered an equinox. It stands for the idea that day and night have equivalent lengths. The sunset and dawn are separated by 12 hours everywhere on Earth. One may observe how quickly the sunset and dawn hours shift throughout the day the farther one goes from the equator.
Whereas, solstices occur in June and December. The contrary is visible close to the solstices. For a few days, both the sunset and sunrise appear to be constant. Over the course of the year, the time of day when the sun is directly overhead where one lives also gradually changes.

Polar bears are not the only species affected by global warming in the Arctic ecosystem. Predict the impact of environmental change on the stability of this fragile ecosystem. (Choose 3)
Answers
Due to the global warming, the temperatures in the Arctic will continue to rise causing the ice sheets to melt and because of that polar bears and other animals might face extinction.
Global warming as well as other environmental changes in the Arctic are having a crucial impact on the stability of the fragile Arctic ecosystem. As the Arctic continues to warm up, ice sheets will keep melting at an accelerating rate. This can possibly have a major impact on the ecosystem, as many of the species, including polar bears as well as the seals, depend on the ice for their survival.

Identify three similarities and three differences in the various types of deserts. Coastal, Hot and Dry, Cold, and Semiarid.
Answers
The primary distinction between hot and cold deserts is that the hot desert is scorched by the sun, whereas the cold desert has ice and snow on the ground.
What is a desert?A desert is a desolate area of land with little precipitation and, as a result, hostile living conditions for plant and animal life.
A hot desert is a region of the world with high average temperatures but little precipitation.
Cold deserts have hot summers but extremely cold winters. In temperate parts of the world, such areas are typically found in high, flat areas known as plateaus or mountainous areas.
A semi-arid climate, semi-desert climate, and otherwise steppe climate is a subtype of dry climate. It is found in areas where precipitation is lower than potential evapotranspiration but not as low as in a desert climate.
Thus, these are some contrast between deserts.
