In order to use only the birth and death rates to calculate the rate of population growth or decrease of a country, the immigration and the emigration rates must either be insignificant or approximately equal.
Population growth rateThe growth rate of a population is determined by the following equation:
Growth rate = (Birth rate - death rate) + (Immigration - Emigration)
Thus, if immigration is more or less equal to emigration or both factors are insignificantly small, the difference between the birth and death rates can be used to estimate the population growth.

Canine teeth are not as useful as it is in animals while archaeopteryx has the character of both birds and reptiles.
What are vestigial organs?The vestigial organs are those organs that have no apparent function in the body which means that the body can do without them.
Examples of vestigial organs in the body are:

Mary loved having her goldfish tank in her office. She said watching the fish swim around was calming to her on stressful days. Mary thought that if 2 goldfish in her tank could make her less stressed then certainly 8 goldfish would be even better. After three days of having 8 goldfish in her tank, she noticed 5 of the fish began to sink to the bottom of the tank becoming less active than the remaining 3. A few days later the 5 sick fish died and the 3 remaining fish thrived. Use the data to help you choose three reasons the carrying capacity of the fish tank wasn’t able to accommodate all 8 goldfish.
A.
There was a limited supply of food available to sustain all 8 fish.
B.
There was an unlimited amount of space for the fish to swim.
C.
The amount of dissolved oxygen in the tank was not replenished quickly enough to sustain all 8 fish.
D.
The ammonia levels in the tank did not compromise the life of the fish.
Answer:
A
C
D
Explanation: Because since C is not right, we can immediately assume that the rest are the answers. It says that 3/4 are right, so it would be ACD, also they make sense.

I have to answer these questions with these graphs made how do i answer them
Answer:
A line graph is also used when there are two variables—but only makes sense when you're tracking changes over a continuous measurement (e.g., time, temperature, distance). Line graphs are especially useful for illustrating direction (i.e., peaks and dips) rather than magnitude.
Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group.

a. It contains the same number of carbon atoms as a oxygen atoms.
b. It contains twice as many carbon atoms as a molecule of glucose.
c. It contains twice as many hydrogen atoms as oxygen atoms.
d. It contains more hydrogen atoms than carbon atoms.
What it will be ?
Answer:
The correct answer is A.
Explanation:
The chemical formula for maltose is C12H22O11. That means there are 22 carbon molecules, 22 hydrogen molecules, and 11 oxygen molecules. You can see that A is untrue because 22 is not equivalent to 11. Meanwhile, all other statements are true.

According to some scientists, which is a cause of global warming? decrease of nitrous oxide changes in cloud cover decrease of methane gas changes in solar energy
Answer:
D.) Changes in solar energy
Explanation:
This is because increased solar irradiation causes the release of methane and carbon dioxide from storage in the seas and icecaps, which can then cause additional warming. I hope this helps! ^-^
According to some scientists, the major cause of global warming based on the options given is changes in solar energy.
What do you mean by Global warming?Global warming may be defined as the situation that unusually or rapidly increases the Earth's average surface temperature over the past century primarily due to the greenhouse gases released by people burning fossil fuels.
An increase in Methane, Carbon dioxide, and nitrous oxide leads to global warming as these all are greenhouse gases.
Therefore, according to the option given above, the major cause of global warming is changes in solar energy.

If the voltmeter shows a neuron's membrane potential becomes more negative, from -70 mV to -85 mV, then the neuron is experiencing a hyperpolarization phase.
What is the hyperpolarization phase?The hyperpolarization phase is a stage in which potassium channels remain open while sodium channels need to reset.
This causes a change in the voltage inside the cell, which triggers a concomitant response.
The period of hyperpolarization is inversely opposite to the depolarization state of the neuron.
