Exponential growth is seen
Given that initial population, at time 0 members =2
i.e. P0 =2
P(2) = 4
In 2 minutes it became 4 times
And in 6 minutes it became 16 members
P(0) =2
P(2) =4
P(6) =16
i.e. every 2 minutes the population doubles
Hence exponential growth of population doubling in 2 minutes
P(t) =
will be the function representing the population at time t.

Explaining Below V
Explanation:
There are 5 different kinds of climates globally.
Tropical
Dry
Temperate
Continental
Polar
Tropical climates are very hot and humid. There's lots of rain (estimated around 59-60 inches per year). The average temperature tends to be over 60°F or 18°C. Plants you can find are incredibly diverse in both plants and animals. You can find animals such as monkeys, parrots, anacondas, jaguars, tigers, and many more. The tropics have the greatest plant diversity on the planet. The climate generally is centered around the equator.
Dry climates are generally very warm and dry. Humidity is very unlikely as everything is mostly dry heat. There's very little precipitation. Dry climates usually consist of deserts (Fe: Sahara desert). Plants such as cacti, succulents, wildflowers, and small trees, shrubs, and grasses. Animals can vary from things such as tarantulas, rattlesnakes, foxes (only some), camels, and rabbits. Depending on the desert, the heat can shoot up past 100°F while being frigid at night.
Temperate climates are generally warm summers with storms and mild winters. Plants can range from owls, raccoons, sparrows, meadowlarks, deer, and occasionally bears. This climate fluctuates the most in temperature compared to other climates. Plants can range from things like clover plants to a common bean.
Continental climates have mediocre summers with very cold winters. In the winter, snowstorms and strong winds are most likely. Sometimes, the temperature can drop below -22°F. Plants can range from Lavender and fern to Carolina Lupine and Silver maples. Animals can consist of squirrels, chipmunks, prairie dogs, skunks, and raccoons.
Polar climates are frigid. Its cold year round. There's animals such as polar bears, foxes, wolves, and caribou. Plants can vary from Tundra moss to Arctic Willow. Plants are generally smaller and are more like tiny shrubs.
Hope this helps.

The sources of information that might be used are ; (i)The spinning of the earth on its axis and (ii) the spinning of other planets on their axis
The relative motion of the earth is the spinning/rotation of the earth on its axis from west to east every 24 hours. every planets in the universe spins in the same direction of the earth ( i.e. from west to east ) except Venus and Uranus whose spins are retrograde.
To determine the relative motion we can observe the movements of other planets that way we can determine the relative motion of Earth in the universe.
Hence we can conclude that the sources of information are The spinning of the earth on its axis andthe spinning of other planets on their axis.

Final answer:
The relative motion of Earth compared to other planets can be determined using Johannes Kepler's laws, gravitational simulations, and NASA studies. Combining these methods can give an understanding of the relative motion within the solar system.
Explanation:
To determine the relative motion of Earth compared to other planets in the solar system, one can use various information sources. These include historical observations and calculations from scientists like the German astronomer Johannes Kepler. Kepler's laws of planetary motion help us understand the motions and orbits of planets in our solar system.
Another reliable source of determining relative planetary motion is gravitational simulations. These virtual simulations allow students and scientists to adjust distance parameters between celestial bodies like the Sun, Earth, and other planets. Changing these distances can clearly demonstrate the influence they have on gravitational forces and their respective orbits.
Lastly, the use of direct data from NASA studies and surveys such as those that captured the motion of Venus across the Sun, can also provide insight into relative motion within the solar system. The combination of all these sources allows for a comprehensive understanding of the relative motion of Earth and other planets in our solar system.

c. is repeated many times to make sure the results are accurate.
d. keeps all variables constant.
Answers
The correct answer is B. Tests experimental and control groups in parallel
Explanation:
In science, a controlled experiment is a type of experiment in which scientist intervene or manipulate variables. This often implies scientists use a control group in which the variable is constant and an experimental group that has a different treatment or changes in the variable studied. This allows scientists to evaluate the effect of the variable by comparing the results of both groups and thus confirm or discard a hypothesis. Therefore, a controlled experiment can be defined as on that "tests experimental and control groups in parallel".
Final answer:
A controlled experiment is one that tests experimental and control groups in parallel, with all other variables kept constant. This enables the scientist to observe the impact of a single variable.
Explanation:
A controlled experiment is one that can be defined as an experimental set up in which the scientist keeps all variables constant, except for the one being studied. The correct option here would be option 'b'. Such an experiment tests experimental and control groups in parallel.
This methodology allows the researcher to observe the effect of one variable on the study subject while ensuring that all other conditions remain the same. For example, if you were to experiment with plant growth, you might keep factors like sunlight, water, and type of soil constant while changing the type of fertilizer used.

b. The nose
c. The pharynx
Answers
Answer:
c. The pharynx
Explanation:
The pharynx is a tubular organ that begins in the funnel-shaped neck down the neck, extending from 12 to 15 cm in length and about 35 mm at its onset and about 15 mm at the end. its ending. It has communication with the esophagus, nasal passages and the ears. The pharynx is located behind the nasal passages and in front of the cervical vertebrae, remains attached to the larynx and esophagus.
Simply put, we can say that the pharynx is a funnel-shaped passageway that connects the nasal and oral cavities to the "voice box," also known as the larynx.
