Answer: The correct answer is- D) Transfer RNA delivers specific amino acids to the ribosome, matching messenger RNA codons.

DNA code of a gene is first converted into mRNA ( messenger RNA) through a process called transcription ( occurs in nucleus of eukaryotes and cytoplasm of prokaryotes). mRNA is then converted into protein through a process called translation ( occurs in the cytoplasm of cell).

During the process of translation, tRNA ( transfer RNA) delivers specific amino acid to the ribosome that matches with the codons ( sequence of three nucleotides in mRNA).

As a result, a long chain of amino acid is assembled, resulting in protein synthesis.

scZoUnD [109]
The answer is Surgical Contraceptive Methods e.g. Vasectomy(For males) and  Tubectomy(Females)<span>.

</span>Vasectomy:- In this method vas deference is cutted and tied so that sperms can't reach uthera.

Tubectomy:- In this method both fallopian tubes are cut and tied, so that no egg can head towards the site of reproduction(Cervix).

Note:- Both process are irreversible.

"Now that you have come up with an equation that describes the relationship between amounts of different nucleotide bases in DNA
Dima020 [189]

Answer:

G - 21%

T - 29%

A - 29%

Explanation:

Nucleotide bases in DNA are complementary. Adenosine (A) binds to Thymine (T) while Cytosine (C) binds to Guanine (G). Hence the composition of A in DNA is the same as that of T; and that of C is the same as that of G.

From the information given, C is 21%

Therefore G is also 21% of the genome as  C is bound to G, the therefore are the same proportion.

C and G make up 42% of the genome (that 21% + 21%).

The remaining 58% (100%-42%) is made up of A + T

Similarly the proportion of A is equal to that of T,

Hence A is 29% (half of 58%) and T is 29%.

How can pesticide use be harmful to human agriculture?
iogann1982 [59]
The Answer is (A) 
Because the pesticide will kill off the bugs and weeds but will damage the soil so after the crops you have in the ground now just will not grow there again until 1 year after the pesticide has washed away

How does global warming affect the water cycle
Gennadij [26K]

Answer:

Climate change is likely hastening aspects of the water cycle as rising global temperatures raise the rate of evaporation globally. On average, higher evaporation leads to more precipitation. According to certain climate projections, coastal regions would get wetter while the center of continents will become drier.

Explanation:

There's many affects: three main ones are evaporation, precipitation, and surface runoff and stream flow.

You can see negative affects on Oceans, snowpack, clouds, and changes in water demand too.

Evaporation

Warmer air has the ability to store more moisture than chilly air. When a result, as the earth warms, the air will absorb more water from the seas, lakes, soil, and plants. The drier conditions left behind by this air might have a significant impact on drinking water supplies and agriculture.

On the other hand, the warmer, wetter air may imperil human life. Greater humidity, according to a research from Columbia University's Lamont-Doherty Earth Observatory, would make future higher temperatures unpleasant in certain regions by preventing the cooling benefits of our perspiration.

Precipitation

When all of that extra warm, more moist air cools, it pours more rain or snow on the earth. As a result, a warmer earth brings more rain and snowstorms. So far, the northeastern United States has seen the greatest rise in the severity and frequency of heavy precipitation events. Since 1979, thunderstorm groups in the Central United States have been more common and have dropped more precipitation.

Climate change will alter where precipitation falls by changing air temperatures and circulation patterns. Some regions, including the American West, Southwest, and Southeast, are anticipated to become drier. Meanwhile, the northern United States and the Midwest are forecast to receive more rain. These precipitation forecasts are already coming true.

According to the National Climate Assessment, the Southwest, southern Great Plains, and Southeast will see more intense and persistent droughts. And the majority of the rest of the country is also at danger of more severe short-term droughts. Researchers at the Earth Institute discovered that climate change may have already increased historical and current droughts, and that drier circumstances are exacerbating wildfires.

Changes in precipitation patterns will put many farmers, as well as natural ecosystems, in jeopardy. Columbia University's International Research Institute for Climate and Society scientists are developing tools and techniques to assist farmers in adapting to these difficulties. Natural ecosystems, on the other hand, may be unable to adapt as rapidly.

Surface Runoff and Stream Flow

Flooding can occur as a result of larger bursts of precipitation generated by warmer, wetter air, which can risk human lives, destroy houses, ruin crops, and harm the economy. Surface runoff — the water that pours over the ground after a storm — will also rise with heavier rainstorms. This rushing water may remove nutrients from the soil as well as sweep up pollutants, dirt, and other unwanteds, draining them into neighboring bodies of water. These toxins may contaminate our water sources and increase the cost of cleaning the water to meet drinking standards.

Furthermore, when runoff deposits sediments and other toxins into lakes and streams, it may endanger fish and other species. Fertilizer runoff may trigger algal blooms, which can suffocate aquatic species and create a nasty mess. The problem is exacerbated by warmer water, which can't store as much dissolved oxygen as fish require to thrive. These circumstances might impair fisheries and make it unpleasant for those who like fishing, swimming, and other recreational activities in lakes and streams.
