Answers

Answer:

-0.50

Explanation:

For the graph displayed, the most probable value of the correlation Coefficient is - 0.50 ; the line of best fit has a negative skoe and hence will have a negative relationship as the correlation Coefficient is a statistical value which measures the degree of relationship between two variables. Also, the distribution of data in the plot does not give a perfect fit, hence a correlation Coefficient of - 1.0 isn't possible for the distribution shown.

Based on what you learned from your research, do you think people should limit their cell phone use? Why or why not?

Answers

Answer:

No.

Explanation:

No, the increasing number of cell phones will not the cause of cancer because it emits low intensity of radio waves. Radiations such as x-rays, gamma rays, alpha particles, beta particles, and neutrons are responsible for causing damage to the cell and the main cause of cancer. High intensity of radio waves heats up the cells not causing cancer disease so we can conclude that the increasing number of cell phones will not cause cancer disease in humans.

This oceanic zone contains some of the
deepest parts of the ocean.
A. Kelp Forest
B. Abyssal Zone
C. Coral Reefs

Answers

This correct answer is the Abyssal Zone

The abyssal zone, which lies between 4,000 and 6,000 meters (13,000 and 20,000 feet) below the surface, is the deepest region of the ocean. So, option B is the answer.

The region of the ocean that lies beyond the continental shelf is commonly referred to as the oceanic zone. The sunshine zone, twilight zone, midnight zone, and abyssal zone are the four vertical zones that make up the open ocean.

Abyssal zone is characterized by high pressure, low temperatures, and very little light.

Kelp forest is found in shallower areas, often between 20 and 100 meters deep and Coral reefs are located in tropical, shallow waters.

Therefore, option B is correct.

Explanation:

If the death and birth number are equal, there are no changes in numbers made.

For the global population growth rate to reach zero, the number of births would have to be same as the number of death.

What do you mean by population growth rate?

Population growth is the increase in the number of people in a population or dispersed group. Actual global human population growth amounts to around 83 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7.9 billion in 2020.

Population in the world is, as of 2022, growing at a rate of around 0.84% per year (down from 1.05% in 2020, 1.08% in 2019, 1.10% in 2018, and 1.12% in 2017). The current population increase is estimated at 67 million people per year.

The world's population is expected to increase by nearly 2 billion persons in the next 30 years, from the current 8 billion to 9.7 billion in 2050 and could peak at nearly 10.4 billion in the mid-2080s.
