For the global population growth rate to reach zero, the number of births would have to be
Answer:
same as the number of death
... is what you fill in.
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.

Match each graph with its correlation coefficient.
+1.0
+0.85
+0.15
-0.50
-1.0
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.

Scientists sink concrete blocks in oceans to create artificial coral reefs. Which successive event most likely occurs first on this type of coral reef
Answer:P
Explanation:got it right
Coral polyps attach themselves to the surface to grow is the event most likely occurs first on this type of coral reef.
What is Coral reef?Coral reefs are significant ocean habitats that make a strong argument for the dangers of climate change. Reefs are a significant contributor to the biodiversity of the planet; they have been referred to as "the rain forests of the seas." One of the most diverse environments on earth, coral reefs are home to 25 percent of all marine species, according to scientists.
According to Paulo Maurin, coordinator of education and fellowships for NOAA's Coral Reef Conservation Program, the reefs are essential to the biodiversity of our world.
Many fish species use them as fruitful nurseries, giving the young fish a place to live and an opportunity to develop, according to him. "The diversity of coral reefs is so great that we don't have a firm count of all the species that live there,"
Therefore, Coral polyps attach themselves to the surface to grow is the event most likely occurs first on this type of coral reef.

Some people worry that the increasing number of cell phones will cause cancer
because of the energy of the radio waves they emit. Cell phones are a new technology
that only recently became widely used. And because cancer takes years to develop, the
amount of risk is not yet known.
K
Research this issue, and summarize what's known so far. In your summary, include
information about the energy of radio waves. Be sure to only use credible sources.
Based on what you learned from your research, do you think people should limit their cell phone use? Why or why not?
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
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.

it is to do with something called angular moment. Gravity is the central force in the Universe, because it is the only one which has a significant pull over large distances.
5:Orbits are the result of a perfect balance between the forward motion of a body in space, such as a planet or moon, and the pull of gravity on it from another body in space, such as a large planet or star. ... These forces of inertia and gravity have to be perfectly balanced for an orbit to happen.

The dynamics of a rotating body is of course controlled by forces like gravity. Kepler's laws are a direct consequence of gravity
