Which factors add to the greenhouse effect and are caused by human activities? Select two options. (This question requires Two answers)
A.a decrease in the amount of dust in the atmosphere
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
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.The picture below shows a simple model of the rock cycle. Use the picture to answer any questions that follow.Which events at point 6 could transform sedimentary rock into igneous rock?
Extreme winds and storms weather the sedimentary rock into particles, which collect in rivers and are compacted into igneous rock.
Rising oceans erode mountains of sedimentary rock into particles, which sink and get compacted into layers that form igneous rock.
Tectonic plates drive sedimentary rock under Earth's surface, where it melts into magma and turns into igneous rock as it cools.
Shifting tectonic plates push the sedimentary rock toward the poles, where it freezes and hardens into igneous rock.
Answer:
Tectonic plates drive sedimentary rock under Earth's surface, where it melts into magma and turns into igneous rock as it cools.

Arctic ice retreat is threatening many species in this ecosystem. Their resources are being cut and they are needing to find new ways to survive. Do you think in your lifetime you will see drastic effects to the species in this ecosystem and why? Will that affect other ecosystems?
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.

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

How do limiting factors impact local ecosystems?
A)Limiting Factors prevent populations in ecosystems form growing any larger. If any of the limiting factors change, animal and plant populations change, too.
B)Limiting factors do not prevent populations in ecosystems from growing any larger. If any of the limiting factors change, animal and plant populations do not change, too.
C)Limiting factors can never impact ecosystems.
D)As biodiversity of an ecosystem increases, the ability to withstand environmental stress due to the loss of a single species or group also increases, improving the sustainability of the ecosystem.
Answer:
limiting factors like the availability of food, water, shelter and space can change animal and plant populations. Other limiting factors, like competition for resources, predation and disease can also impact populations. ... Sometimes a population will grow too large for the environment to support.

explain how the products of photosynthesis are stored leaves!
Answer:
The products are stored in the form of starch because glucose is soluble
Explanation:
Answer:Although the cuticle provides important protection from excessive water loss, leaves cannot be impervious because they must also allow carbon dioxide in (to be used in photosynthesis), and oxygen out. These gases move into and out of the leaf through openings on the underside called stomata.

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
Answer:
it is b

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.

A newborn child was brought to the hospital nursery before he was marked with his parents' names. The hospital workers must use what they know
about genetic outcomes to determine whom the child belongs to. They use his traits to help them. The baby has freckles (F dominant), and attached
earlobes (I recessive). They believe that the baby most likely belongs to a couple in which the man has attached earlobes but no freckles. It is known that
the woman is heterozygous for freckles and earlobe type.
Complete the Punnett square below to determine the probability that the child belongs to this couple. List the possible combinations of the father's
