B.a decrease in the amount of water on Earth’s surface
C.an increase in gases in the atmosphere that absorb heat
D.an increase in surfaces that radiate energy into the atmosphere
E.an increase in the amount of solar radiation that reflects into space

Answers

Answer:

There is overwhelming evidence that human activities, especially burning fossil fuels, are leading to increased levels of carbon dioxide and other greenhouse gases in the atmosphere, which in turn amplify the natural greenhouse effect, causing the temperature of the Earth's atmosphere, ocean, and land surface to.Human activities contribute to climate change by causing changes in Earth's atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere.

Explanation:

EXAMPLES: Burning of Fossil Fuels: Fossil fuels like coal, oil and natural gas have become an integral part of our life. ... Deforestation: Forests hold a major green area on the planet Earth. ... Increase in Population: Over the last few decades, there have been huge increase in the population.

Line t passes through (4, 5) and is perpendicular to the line shown on the coordinate grid.

a coordinate plane with a line passing through two points at 0 comma 3 and 7 comma 2

What is the equation of line t in standard form?

x − 7y = −161
7x − y = 23
−7x − y = 23
x + 7y = 161

Answers

Answer:

it is b

Explanation:

The equation of line t is [tex]7x-y=23[/tex]

Equation of line :

Given that , A line passing through two points [tex](0,3),(7,2)[/tex]

Slope of line is,

                   [tex]m=\frac{2-3}{7-0}=-\frac{1}{7}[/tex]

Since, line [tex]t[/tex] and given line are perpendicular to each other.

Slope of line [tex]t[/tex] is, [tex]=7[/tex]

Equation of line [tex]t[/tex] is, [tex]y=7x+c[/tex]

Line [tex]t[/tex] passes through [tex](4, 5)[/tex]

Substitute point in equation of line [tex]t[/tex].

             [tex]5=28+c\\\\c=-23[/tex]

Equation of line [tex]t[/tex] become, [tex]y=7x-23[/tex]

Answers

Answer:

no

Explanation:because they will find new ways to survive in the environment

Answer:

We are already seeing drastic effects to the ecosystem and it's wide assortment of species. Animals such as polar bears, and seals are losing their breeding and hunting grounds. Polar bears in particular are losing their ways to catch seals for food and interbreeding with grizzly bears. Fish and whales from warmer parts of the world are starting to move up north and are becoming invasive. Most importantly, since cold water from the melting ice are mixing with ocean currents, global climates and weather systems are changing course. Ultimately, in about 500 years, there could be a large Global Climatic Shift that may put us into another Ice Age.

A. made of a cell or cells

C. respond to surroundings

Answer:

Option D) - Spontaneously generate.

Answer:

Spontaneously generate

Explanation:

all living things have cells, are similar chemically (like have water) and respond to surroundings.

Spontaneous generation refers to an obsolete body of thought on the ordinary formation of living organisms without descent from similar organisms. The theory of spontaneous generation held that living creatures could arise from nonliving matter and that such processes were commonplace and regular.

Which agent would cause the least damage to a chromosome?

Answers

Hey there!

The answer would be ultrasound.


The ultrasound is considered safe because it uses sound waves for the detection of tissue, organ, baby etc. These waves are considered safe and transfer only a small amount of heat to the tissue in which the ultrasound is done. A little amount of heat is not at all harmful to the body in any means. Early defects of baby can be detected through this procedure, the merits of the process is much higher than its demerits.

Answers

D because they evolved into the special that are current now

Fossils of species that no longer exist but are ancestors of current species have been found in rock layers. Thus, the correct option is D.

What are Fossil fuels?

A fossil fuel is a hydrocarbon-containing material which is formed naturally in the Earth's crust from the remains of dead organisms such as plants and animals which are extracted and burned as a fuel. The main fossil fuels which are present in the earth's crust include coal, oil, and natural gas.

The evolution of species is easily confirmed by the presence of fossils of the most diverse species of the living beings in the world. This is because, fossils are the records of species which do not currently exist, however there are existed millions of years ago and are similar to the current species, being their ancestors.

Therefore, the correct option is D.

Which of these locations is most likely to experience moderate climate throughout the year?

Answers

Answer:

b

Explanation:

The location that is most likely to experience moderate climate throughout the year is C.

The location C of the map will experience moderate climate because it is a coastal region of the map.

Moderate climate weather is described as a weather condition that occurs during the day, as cool air from sea rush towards the land and during night, as cool air from the land rush towards sea.

Because location C is a coastal region which means that the location is surrounded by land which better absorbs and radiates heat much faster than sea.

Therefore, the location that is most likely to experience moderate climate throughout the year is C.
