Answer:

"Carbon dioxide (CO2) is one of a number of gases that are transparent to the visible light falling on the Earth from the Sun, but absorb the infra-red radiation (heat) emitted by the warm surface of the Earth, preventing its loss into space. During the geological history of the Earth the level of atmospheric CO2 has varied considerably and this has had an impact on the global temperature. A significant amount of this atmospheric carbon was sequestered or (removed from the atmosphere) and turned into inert material (coal, and oil) typically 300-360 Million years ago. All of the global ecosystems and species have adapted to a lower level of atmospheric CO2 and critically, human civilisation has also grown since that period.  Since the industrial revolution humans have been burning sequestered CO2 in the form of coal, oil, and natural gas which has the result of releasing energy but also releases CO2 back into the atmosphere".

Answer:

true

Explanation:

because an element is of one type of an atom.

A molecule is made of two or more atoms held together by chemical bonds and if two atoms that form a molecule are of the same element form a diatomic molecule.

A molecule that consists of two or more atoms of different elements it forms a chemical compound.

Answer:

float

Explanation:

since everything that have a density more than 1g/l (not g/ml) will sink and less than that will float

then 1.9g/ml < 1g/l

Answer:

it would sink

Explanation: it would sink because the density of water is 0.997 m/ml and 1.9 is more then that

Answer:

ampiltude

Explanation:

Amplitude means a measure of the amount of energy in a wave. Notice in the drawing below how the amplitude measures the height a wave is going above or below the resting position of the wave.

Answer:

Explanation:

A crest point on a wave is the maximum value of upward displacement within a cycle. A crest is a point on a surface wave where the displacement of the medium is at a maximum. A trough is the opposite of a crest, so the minimum or lowest point in a cycle. When the crests and troughs of two sine waves of equal amplitude and frequency intersect or collide, while being in phase with each other, the result is called constructive interference and the magnitudes double (above and below the line). When in antiphase – 180° out of phase – the result is destructive interference: the resulting wave is the undisturbed line having zero amplitude.

Answer:

DNA viruses contain usually double‐stranded DNA (dsDNA) and rarely single‐stranded DNA (ssDNA). These viruses replicate using DNA‐dependent DNA polymerase. ... Compared to DNA virus genomes, which can encode up to hundreds of viral proteins, RNA viruses have smaller genomes that usually encode only a few proteins.

Explanation:

Answer:

Difference Between DNA & RNA Viruses

A virus can self-replicate inside a host cell. ... The viruses that contain DNA as their genetic material are called the DNA viruses. RNA viruses, on the other hand, contain RNA as their genetic material. DNA viruses are mostly double-stranded while RNA viruses are single-stranded

Explanation:

The United Nations International Panel on Climate Change’s (IPCC) 2013 climate change science report states with “90 to 99 percent certainty” that more frequent and more severe weather events like droughts, intense heat waves, and “more frequent/ intense heavy rainfall events” are a consequence of the climate crisis. And it is communities of color that are bearing the brunt of those events, say many experts.

Other communities of color are also feeling the heat. In California, for example, record heat waves and droughts are affecting Latino communities hardest throughout the state, says Mario Santoyo of the California Latino Water Coalition.

As state farmers see their fruit and vegetable crops shrink from lack of water, it’s the state’s majority-Latino farmworkers who are struggling most as a result, as they scramble to get enough hours picking crops to earn a livable wage.

Explanation:

RR , Rr , Rr all result in dominant trait

Answer:

In many areas, rain or snowmelt on seasonally frozen soil is the single leading cause of severe runoff and erosion events. As soils freeze, ice blocks the soil pores, greatly diminishing the permeability of the soil. This is aggravated by the tendency of water to migrate to the freezing front, causing elevated ice content and frost heave.

Explanation: Specialized Structures. ... This is because different organisms have developed unique structures that perform these functions and that do so in ways that fit their specific environments. So in this case, the structures are specialized to perform a specific function but also to fit the needs of a specific organism.

Due to unique structure an organism perform similar function if the structures are different.

Different structures perform the same function because different types of organisms have developed unique structures that helps them to perform function that is specific to their environments. The structures are specialized to perform a specific function but also to fit the needs of a specific organism.

Analogous structures refers to those structures which perform same function, but have different structures. Such type of organisms belongs to different ancestry but their body parts perform similar function so we can conclude that due to unique structure an organism perform similar function if the structures are different.
