Which factor will increase a population's size?A.) High birthrate
B.) High death rate
C.) High emigration rate
D.) High predation rate

Answers

Answer 1
Answer:

The factor that will increase a population's size is High birthrate. Therefore, option (A) is correct.

High birthrates can grow populations. Population expansion occurs when the birthrate surpasses the death rate. Birthrate is the number of births per population per time period.

High death rates reduce population size. A population shrinks when the mortality rate exceeds the birthrate. Emigrants leave the population to live elsewhere. This may reduce population size. Predator predation rate is high. Predation decreases prey species populations but does not directly increase them.

Today, it is Moore's turn to measure the earthworms. For theworm above, Moore records a length of 6.0 cm. Explain whether Moore's recording is accurate and why.A)The earthworm length is shorter than 6.0 cm because the worm is curved.B)The earthworm length is shorter than 6.0 cm because Moore used theincorrect units.C)The earthworm length is longer than 6.0 cm because the worm needs tobe straightened.D)The earthworm measurement is accurate because Moore subtracted thebeginning and ending points from the ruler.

In living organisms DNA does not usually exist as a single molecule, but ...... Levene suggested that DNAconsisted of a string of nucleotide units
DNA is made up of three subunits: a deoxyribose 5 carbon sugar, a phosphorous group, and a nitrogenous base (adenine, thymine, guanine, cytosine). All in all, these are called nucleotides that wrap around in a double helix in order to form DNA.

Washington has the most waterways that still fail to meet the standards.

What is Clean water act?

The Cuyahoga River in Ohio was so contaminated by industrial pollutants in 1969 that it caught fire.

The historic CLEAN WATER ACT was enacted by Congress in 1972 in response to public outcry about polluted rivers. The historic rule was created to guard against pollution and devastation of all of our waters, from the tiniest streams to the mightiest rivers.

The Clean Water Act has prevented billions of pounds of pollution from entering our rivers and increased the number of streams in the country that meet clean water standards, which has a direct positive impact on drinking water, public health, recreation, and wildlife.

Therefore, Washington has the most waterways that still fail to meet the standards.

How is gravity affected by mass and radius?

Answers

Gravity is directly proportional to the difference in mass ( thus, the greater the difference in mass of two objects, the greater the gravity).

Gravity is inversely proportional to the square of radius between two objects ( thus, the greater the distance from radius, thus, the lesser the gravity)

* Well if you mean the radius of an object, then it is directly proportional; greater the radius, greater the gravity.*
