Answer: The impact of so many humans on the environment takes two major forms: consumption of resources such as land, food, water, air, fossil fuels and minerals. waste products as a result of consumption such as air and water pollutants, toxic materials and greenhouse gases. Population is growing rapidly, far outpacing the ability of our planet to support it, given current practices. Overpopulation is associated with negative environmental and economic outcomes ranging from the impacts of over-farming, deforestation, and water pollution to eutrophication and global warming. Fossil fuels produce large quantities of carbon dioxide when burned. Carbon emissions trap heat in the atmosphere and lead to climate change. In the United States, the burning of fossil fuels, particularly for the power and transportation sectors, accounts for about three-quarters of our carbon emissions. Population density can have a negative impact on our environment and natural resources. These pressures can lead to deforestation, result in overcrowding, and could lead to the destruction of our planet's delicate ecosystem. Growing populations use large amounts of nonrenewable resources like timber, coal, and oil. Irrigation, for example, uses per calorie less land but more water, fertilizer, and/or capital. The variation of land quality also interacts with development. Population growth increases food demand and therefore the demand for agricultural land. Poverty is believed to be the leading cause of overpopulation. A lack of educational resources, coupled with high death rates leading to higher birth rates, result in impoverished areas seeing large booms in population.

Answer:

Intensity

Explanation:

The intensity of sound waves determines the loudness of sounds, but what determines intensity? Intensity results from two factors: the amplitude of the sound waves and how far they have traveled from the source of the sound.

Answer:

An egg or sperm only has half of the parent's sex chromosome pair. An egg will always have an X chromosome, since the woman's sex chromosome pair only has Xs. Sperm can have either an X chromosome or a Y chromosome. If a sperm with an X chromosome fertilizes the egg, the new cell will have two X chromosomes. One came from the father's sperm and one came from the mother's egg. Since the sex chromosome that is made is XX, the cell will grow into a girl baby.

Explanation:

Hope this helped Mark BRAINLIEST!!

mixing occur before the chromosomes are sorted into individual sperm or egg cells. Chromosomes from each pair in a mother or father, respectively, make contact and exchange pieces of DNA, creating hybrid chromosomes.

A chromosome is a thread-like structure present in the nucleus of cells such as plant, animal and human cells and it is made of a molecule of DNA (Deoxyribonucleic acid) and histone proteins.

It is composed of three components, DNA, proteins and RNA,  amount of the DNA content ranges from 30 to 40 %, the amount of proteins from 50 to 65%, and small amount of RNA from 1 to 10%.

Two types of protein present in DNA such as histone and non-histones proteins, histone constitute large amount (90% of total protein), whereas non-histone is present in small amount (around 10% of total protein).

Answer:

a. As CO2 increases, the temperature also increases.

Explanation:

Carbon dioxide (CO2) is an atmospheric molecule produced naturally via respiration or artificially via burning of fossil fuels. CO2, as rightly stated in this question, has been referred to as a greenhouse gas because it acts to trap the sun’s heat on Earth.

Logically, an increase in the amount of greenhouse gas like CO2 released into the atmosphere means an increase in the greenhouse effect or global warming (increase in global air temperature). However, according to the GRAPHICAL REPRESENTATION in this question, an increase in the ppm concentration of CO2 led to an increase in the temperature (°F) of the globe over the years.

As depicted on the graph, at a CO2 concentration of 390ppm, the relative temperature was at over 1°F.

I did the test I got it right

Answer:

The answer is 80%.

Explanation:

The relative humidity will be 80 %.

The amount of water vapor in the air, represented as a proportion of the highest quantity of water vapor the air could contain simultaneously temperature, was known as humidity levels, referred as relative humidity.

Calculation of relative humidity.

It can be calculated as:

Relative humidity = Actual vapor / saturation vapor density × 100

Relative humidity = 14 / 18 × 100

Relative humidity = 0.7777 × 100

Relative humidity = 77%.

Therefore, the relative humidity will be 77 %.

The pond that should be most  likely to lead to terrestrial succession should be considered as the pond d.

In terms of terrestrial ecosystems, the succession should arise either at the primary or the secondary succession. here the primary succession should be the type of succession where it arise at the time when the area should experience the disturbance.

Answer:

Ocean desalination, Using nuclear fusion as an energy source  and using stem cell technology to cure disease.

Explanation:

Ocean desalination  is the major problem that occurs due to removing of nutrients that is present in the ocean water because of human activities. These nutrients are essential for the marine animals so for solving this problem, we should use other alternative energy resources in order to reduce ocean desalination. Using nuclear fusion as an energy source is a good idea but it can't be implemented on the earth because it requires 100 million degrees Celsius which is impossible to generate. Using stem cell technology to cure disease is a great idea which can cure many diseases in the human body. This available technology is used by replacing damaged cells with the healthy cells.
