The energy required for the chemical reaction of 21.7 grams of nitrogen to produce ammonia is -71.1 KJ/mol.

A chemical reaction is the process which involves a change in the chemical composition of compounds. It involves formation of new chemical bonds between atoms.

In this case, since the formation of ammonia by starting with nitrogen and therefore hydrogen is:

N₂ + 3H₂ ⇒ 2NH₃

This chemical reaction has energy:

ΔfH(NH₃) = -45.90 KJ/ mol

We can compute the energy required for this chemical reaction by first computing the moles of ammonia yielded by 21.7 grams of nitrogen (28.02 g/mol) via stoichiometry:

nNH₃ = 21.7 N₂ × 1 mol N₂/ 28.02g N₂ × 2 mol NH₃/ 1 mol N₂ = 1.55 mol NH₃

Thus, the energy turns out:

Q = n NH₃ ΔfH(NH₃) = 1.55 mol NH₃ × -45.90 KJ/ mol

Q = -71.1 KJ

Hence, the ΔH of the chemical equation will be = -71.1 KJ/mol

tRNA makes up the ribosomal sub units and reads the mRNA as it is made up of two sub units where the mRNA is attached to the lower unit and it reads the mRNA that is doing proof reading as well.

What is the full form of tRNA ?

The full form of tRNA is transfer RNA.

Ribosome is the unit of the cell that is responsible for the protein synthesis and these make up the cells' proteins.  rna polymerase is responsible for synthesising the RNA strand and continuing the synthesis.

tRNA is the transfer RNA that containsw the two ribosomal subunits where the two of the units are joined together and on the lower unit is the mRNA attached to which the amino acid synthesis take place and that reading is done by the tRNA is done in order to check the pattern as per the instructions.

Answer:

A lot of sunlight

Explanation:

Although taigas and tundra's have colder climates, they receive a lot of indirect sunlight. Tropical rainforests receive a lot of sunlight as well.

The exchange of chromosomal segments between nonsister chromatids during meiosis is known as crossing over or recombination. Genetic diversity is increased by the cross-over of novel gene combinations that do not exist in either parent in the gametes.

When homologous chromosomes are fully coupled during the pachytene stage of meiosis, crossing-over takes place. Chiasmata, which retain the two homologs of a bivalent together until segregation at anaphase I, are apparent as the sites of crossing-over at diplotene, when homologs split.

To boost genetic variety, a process called crossing over takes place between homologous chromosomes. An exchange of chromosomal segments occurs during crossing over. The outcome is a hybrid chromosome with a distinctive genetic material pattern.

The maximum to minimum body water loss occurs by: Urine production, Skin losses, Lung respiration and minimum by Feces

Through breathing, sweating, and peeing, the body continuously loses water. You become dehydrated if you don't drink enough water or other liquids.

The majority of fluid loss happens through the stools, sweat, and urine, but it's not only those things. The quantity of body fluid lost daily through the skin, respiratory system, and water in the feces that cannot be readily measured is known as insensible fluid loss.

Physical exercise also influences increased respiratory water loss due to the increased expiratory volume and frequency of breathing. Various environmental elements like temperature, humidity, radiation, and atmospheric pressure mostly affect sweating and urine water loss.

-They have the same functions

Explanation:

A cell wall is present in a plant cell to keep its structure and rigidity. They are made from cellulose.

All plant cells have a nucleus, ribosomes, mitochondria and cell membrane and they all have the same functions as they would have in an animal cell.

Statement 1 is false as plant cells are eukaryotic, which means they have a nucleus.

Statement 2 is also false because a plant cell needs a cell membrane to separate the vacuole and the organelles.

The differences in beak shape are examples of the biological adaptation of the birds to obtain food.

Biological adaptation is a characteristic of an organism's phenotypic traits in relation to environmental selection pressures. Adaptive features are those that have form and function characteristics that enable the organism to successfully sustain the synergy between a feature's biological purpose and a stated selection force. The quantity of energy required to sustain the synergy can be used to gauge how well an adaptation is working, with lower energy requirements suggesting better adaptation.

An external anatomical feature called the beak, bill, or rostrum is usually present in birds but can also be seen in turtles, non-avian dinosaurs, a few mammals, and other animals. To eat, groom, manipulate things, kill prey, battle, probe for food, court, and feed young, an animal uses its beak.

Pesticides such as DDT cause liver tumors in mice and cancer in humans.

what is DDT ?

The first of the current synthetic pesticides, DDT (dichloro-diphenyl-trichloroethane), was created in the 1940s. Malaria, typhus, and other human illnesses spread by insects were the first to be successfully treated with it in both military and civilian populations. Additionally, it worked well to control insects in houses, institutions, gardens, dwellings, and crop and livestock production. Due to DDT's widespread usage and early effectiveness as a pesticide in the US and other nations, many insect pest species have developed resistance to it.

DDT is:

a substance that is known to be extremely persistent in the environment, builds up in fatty tissues, and

in the high atmosphere, may travel great distances.

Although the concentration of DDT in the environment and animals has dropped since it was no longer used in the United States, residual danger from earlier usage is still present due to its persistence.

Seacoasts are land. Coastlines are where land meets water. Waves, tides, and currents form coasts. Waves degrade land.  For example: Great Ocean Road, Australia.

The coastline is the area of a shoreline where land and water converge. Coastlines are shaped in part by currents, tides, and waves. The ground is eroded or worn away when waves crash upon the shore.

Coastal regions can be divided into four categories: emergent, submergent, discordant, and concordant. Submergent beaches have sunk below the water, while emerging coastlines have protruded from it.

Beaches, mudflats, cliffs, and caverns are just a few of the many varied characteristics of coasts. These coastal characteristics are shaped by tides, waves, and water currents (flow). Glaciers, which are massive rivers of ice, and volcanic lava flow both alter some beaches.

The three requirements for a trait to become more common over time in a population area;

Traits are qualities or characteristics that are shared between living organisms as a result of the transfer of these traits from parents to offspring.

Traits are determined by genes.

Genes are the basic unit of inheritance. Genes are regions of DNA that code for a particular product.

The combination of the genes present in an organism is responsible for the traits that are observed in organisms.

The combination of genes in an organism is known as the genotype whereas the observable traits in an organism is known as the phenotype.

Genes for a particular trait in an organism have alternate forms known as alleles. When an organism has similar copies of the allele for a trait, the organism is said to be homozygous for that trait, but when an organism has different alleles for a trait, the organism is said to be heterozygous for that trait.

Several of the cones are "less active" in the absence of daylight, which makes colors harder to discern. As a result, yellow is easier to notice at night since there is less light to aid in color perception.
