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

Explanation:

Why is hydrogen a “cleaner” fuel source than gasoline?

hydrogen is natural created and in the air already, gas is a fossil fuel and is killing the Ozone layer.  carbon dioxide is a poison and can really harm us and the world.

this paragraph basically explains the question

Compared to the carbon dioxide that is produced when we burn gasoline, ethanol, and other carbon-containing fuels, the water produced by burning hydrogen has a less harmful effect on Earth’s climate. If we can power our cars with hydrogen without producing carbon dioxide, then why don’t more vehicles use hydrogen fuel? Unfortunately, the technology needed to use hydrogen as a fuel is expensive, and storing hydrogen fuel can be difficult. Also, the most common way of getting pure hydrogen is by separating it from substances that contain carbon—so although burning hydrogen fuel does less harm to Earth’s climate than burning carbon-containing fuels, the production of hydrogen fuel is still a problem for scientists trying to reduce climate change.

Answer:

let's be honest, chocolate may be a solid but it's both liquid and solid and the reason why it smells is bc the chocolate bar releases gas or some smell or it has a reaction. Many solid release gases.... or a smell

Volatile aromatic molecules found in chocolate are responsible for the smell of chocolate.

All forms of matter can exist in three most common states, which are:

During change of state of matter, solids can change to gas or liquids.

In the case of chocolate, in addition to the solid molecules, it contains volatile aromatic molecules which are responsible for the the smell of chocolate.

Answer:

Many scientists use dichotomous keys to identify plants, animals, and other organisms. They may also use dichotomous keys to identify species, or to determine whether a particular organism has been identified and described before. However, dichotomous keys are not used only to identify organisms.

Explanation: Scientists: Botantist, Cytoligist, Agronomist.

Hope this helps!!

Dichotomous keys are used in research to identify organisms like plants, animals, and microorganisms. Botanists, Agronomists, and Cytoligist can use dichotomous keys.

Dichotomous keys are the identification method of a group of organisms based on the alternative characters and divisions. They identify an organism based on immutable features.

Botanists study plants, Cytoligist study the function and structure of cells, and Agronomists study crop plants and soil. These types of scientists use the key to identify plants and animals.

Therefore, many scientists like Botanists, Agronomists, and Cytoligist use dichotomous keys.

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.

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

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:

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.

Answer:

Rosalind Elsie Franklin (25 July 1920 – 16 April 1958)was a British biophysicist and X-ray crystallographer who made critical contributions to the understanding of the fine molecular structures of DNA, RNA, viruses, coal and graphite. The DNA work achieved the most fame because DNA (deoxyribonucleic acid) plays essential roles in cell metabolism and genetics, and the discovery of its structure helped scientists understand how genetic information is passed from parents to children.

rosalindfranklin

Franklin is best known for her work on the X-ray diffraction images of DNA which led to discovery of DNA double helix. Her data, according to Francis Crick, was "the data we actually used" to formulate Crick and Watson's 1953 hypothesis regarding the structure of DNA.Franklin's X-ray diffraction image confirming the helical structure of DNA were shown to Watson without her approval or knowledge. Though this image and her accurate interpretation of the data provided valuable insight into the DNA structure, Franklin's scientific contributions to the discovery of the double helix are often overlooked. Unpublished drafts of her papers (written just as she was arranging to leave King's College London) show that she had independently determined the overall B-form of the DNA helix and the location of the phosphate groups on the outside of the structure. However, her work was published third, in the series of three DNA Nature articles, led by the paper of Watson and Crick which only hinted at her contribution to their hypothesis.

After finishing her portion of the DNA work, Franklin led pioneering work on the tobacco mosaic and polio viruses. She died in 1958 at the age of 37 from complications arising from ovarian cancer.
