Answers

Answer:

Protein/nucleic acid/Carbohydrates/lipid

The correct and most appropriate words to fill in the blanks are: peptide, water and protein.

An amino acid can be defined as a simple organic chemical compound that is made up of an acidic carboxyl group (COOH), a basic amino group ([tex]NH_2[/tex]), and a variable (unique) side chain group.

Generally, an amino acid is typically named after two (2) of its functional groups and these are:

An acidic carboxyl group (COOH): it acts like an acid.A basic amino group ([tex]NH_2[/tex]): it acts like a base.

Basically, a peptide bond is formed between two amino acids when they unite. Also, this chemical reaction lead to the release of a molecule of water.

Finally, the union of many amino acids forms a macromolecule called a protein.

In conclusion, protein is a macromolecule which is formed as a result of the union of many amino acids.

Which is an environmental factor that would MOST LIKELY have an adverse impact on the stability of an ecosystem?

Answers

It is desserts and oceans because the water helps

The climate change would most likely exhibit an adverse influence on the stability of an ecosystem.

Climate change impacts on ecosystems:

Climate change influences ecosystems in numerous ways. Warming may make the species to migrate to higher elevations or latitudes where temperatures are more favorable.

Climate change is resulting in the elevation of sea level, resulting in intrusion of seawater into the freshwater system, which is forcing the key species to relocate. Thus, removing the prey or predators, which are essential for the stability of the ecosystem.

Due to climate change, the vegetative biomes in the United States is predicted to change across 5 to 20 percent by 2100. A specific species due to climate change ca ripple through a food web and influence a broad array of other species, thus, disrupting the food web.

Change in climate and shift in ecological conditions could support the spread of parasites, pathogens, and diseases with potentially adverse influences on agriculture, human health, and fisheries. Climate change, along with pollution and habitat destruction is one of the stressors, which can result in the extinction of species.

Thus, climate change is the environmental factor, which would most likely exhibit an adverse influence on the stability of the ecosystem.

The author suggestion to mitigate this is to convert underground facilities such as oil and gas wells that previously held fossil fuels until they were pumped out. The author claims that the technology to do so is already present and that there are ways this could be made inexpensive.

Clues:
a. DNA is made of nucleotides.
b. Protein is made of amino acids.
c. DNA is located exclusively in the nucleus.
d. Protein is synthesized exclusively in the cytoplasm.

Answers

Answer:

The two problems that the transfer of information from DNA to protein must overcome are:

How to bring the information from the nuclear DNA to the place of protein synthesis?How to convert this DNA information into amino acids and then into proteins?

Explanation:

The genetic information is found in the DNA and depends on a specific sequence of nitrogenous bases. This information is transcribed into the messenger RNA, whose base sequence is organized into triplets and codons, each of which encodes an amino acid, as well as establishing the pattern for starting and stopping the synthesis of a protein.

How to bring the information from the nuclear DNA to the place of protein synthesis?

The DNA must be transcribed into messenger RNA (mRNA), a process that occurs in the nucleus of the cell. mRNA leaves the nucleus and travels to the cytoplasm, where amino acid synthesis will take place.

How to convert this DNA information into amino acids and then into proteins?

Once in the cytoplasm mRNA binds to ribosomes, structures in charge of translating the sequence of nitrogenous bases RNA to synthesize amino acids. The set of ribosomes and rough endoplasmic reticulum are in charge of the assembly of amino acids to produce peptides and proteins.

The tall buildings that make up the landscape of these urban environments are becoming greener. People are trying to help the environment and have found that green roofs are one way to do so. By planting grass and small shrubbery on the tops of buildings, the environment is getting a helping hand.It is more expensive to build a green roof than it is to lay asphalt or shingles on a roof, but the trend is growing. The basic green roof requires a frame, waterproof membrane, gravel for drainage, fibrous material to retain moisture, soil for planting, and a barrier that prevents roots from penetrating the building.Green roofs started in Europe and are now gaining a strong foothold in the United States. The largest green roof in New York City is built on the roof of a processing and distribution facility. It is actually the biggest green roof in the country. Being in New York, it has faced snow, rain, freezing, and thawing. It has survived it all.The city of Chicago, Illinois, now has more green roofs than any other U.S. city. There are 7 million square feet of green roofs planted across the city. Toronto, Canada, is the first city in the western hemisphere to mandate green roofs on all new tall buildings. Green roofs are beneficial, not only to the environment, but also to the cities that build them.

The full title of the book is Tea Leaves: Being a Collectionof Letters and Documents Relating to the Shipment of Tea to the AmericanColonies in the year 1773, by the East India Tea Company.1 Our numbers were between twenty-eight and thirty. . . . I had but afew hours warning of what was intended to be done. We first talked of[setting fire to] the ships, but feared the fire would [spread] to thetown. We then proposed sinking them, but dropped that [idea]through fear that we should alarm the town before we could [finish.]2 We had [noticed] that very few persons remained on board theships. So, we finally concluded that we could take possession of them,and discharge the tea into the harbor without danger or opposition.To prevent discovery, we agreed to [dress] to resemble Indians asmuch as possible. [We smeared] our faces with grease and lamp blackor soot, and should not have known each other except by our voices.Our most intimate friends among the spectators had not the leastknowledge of us.3 At the appointed time, we met in an old building at the head of thewharf. We fell in one after another, as if by accident, so as not to excitesuspicion. We placed a sentry at the head of the wharf, another in themiddle, and one on the bow of each ship as we took possession. Weboarded the ship moored by the wharf1. Our leader, in a very stern andresolute2 manner, ordered the captain and crew to open the hatchways.[He ordered them to] hand us the hoisting tackle and ropes, assuringthem that no harm was intended them. The captain asked what weintended to do. Our leader told him that wewere going to unload the tea, and ordered himand the crew below. They instantly obeyed.4 Some of our number then jumped into thehold, and passed the chests to the tackle. Asthey were hauled on deck, others knockedthem open with axes. Others raised them tothe railing and discharged their contentsoverboard. All who were not needed fordischarging this ship went on board theothers, [tied] them to the wharf, where thesame ceremonies were repeated. We weremerry, in an undertone, at the idea of makingso large a cup of tea for the fishes.
