Answer:

It is an important part of many cells and processes such as amino acids, proteins, and even our DNA. It is also needed to make chlorophyll in plants, which is used in photosynthesis to make their food. As part of these life processes, nitrogen is transformed from one chemical form to another.

Explanation:

Some questions to clarify;

How does nitrogen help plants?

Nitrogen is so vital because it is a major component of chlorophyll, the compound by which plants use sunlight energy to produce sugars from water and carbon dioxide (i.e., photosynthesis). It is also a major component of amino acids, the building blocks of proteins. Without proteins, plants wither and die.

How does nitrogen help humans?

It is used to make amino acids in our body which in turn make proteins. It is also needed to make nucleic acids, which form DNA and RNA. Humans or other species on earth require nitrogen in a 'fixed' reactive form. Till 1900 we had an access to use naturally occurring nitrogen for processing food like manure

Nitrogen also:

Nitrogen is a key element in the nucleic acids DNA and RNA, which are the most important of all biological molecules and crucial for all living things. DNA carries the genetic information, which means the instructions for how to make up a life form

Nitrogen is also helps runs power plants.

Answer:

Different bird species have differently shaped beaks because each species has evolved a beak design that suits its diet and lifestyle. Beaks function somewhat as human tools do, and they help the birds to access food.This enables the birds to sip nectar from inside flowers.

Answer:

Is D

Explanation:

Nucleic acids are giant biomolecules made of monomers called nucleotides. Nucleotides have three components: pentose sugar (5-carbon sugar), phosphate group, and nitrogenous base.

A nucleotide is the monomer of a nucleic acid. Thus, the correct option is D.

A monomer may be defined as a molecule that can typically form a bond with other molecules in order to derive an entire set of molecules known as a polymer.

Nucleotide generally forms covalent bonds with other nucleotides in order to derive a polymer which is commonly known as nucleic acid.

A nucleotide consists of a pentose sugar molecule attached to a phosphate group and a nitrogen-containing base.

The phosphate group of one nucleotide is covalently joined to the third carbon atom of the pentose sugar of the next nucleotide.

Therefore, a nucleotide is the monomer of a nucleic acid. Thus, the correct option is D.

Independent variable: Adding/not adding soil.

Dependent variables: Does the plant grow? Amount of leaves, plant length.

Controlled variables: Type of plant used, amount of sunlight received, pot used for plant, amount of water given, temperature of soil, etc.

Explanation:

Independent variable: The thing that you want to change. To see if plants need soil to grow, you would need to either add or remove soil altogether.

Dependent variables: The thing that is being measured. By adding your independent variable, you should be able to answer certain questions.

Controlled variables: Things you want to keep the same for each experimental group. For example, if you used different plants, your results could be affected negatively as some plants might rely on soil less than others/grow at a slower or faster pace.

Answer:

Complex Carbohydrates: Also know as polysaccharides (poly = many), these carbohydrates have more than two units of glucose (sugar) linked together. Polysaccharides are generally not sweet and are not water soluble. Starches and dietary fiber are complex carbohydrates.

Complex carbs pack in more nutrients than simple carbs. They're higher in fiber and digest more slowly. This also makes them more filling, which means they're a good option for weight control. They're also ideal for people with type 2 diabetes because they help manage blood sugar spikes after meals.

Simple carbs — also known as simple sugars — contain one or two sugar molecules, whereas complex carbs have three or more. A simple sugar may be a mono- or disaccharide.

In this experiment the dependent variable is the number of mosquito bites, the independent variable is the type of repellent the control group is the population that is not sprayed.

Changing all of the first codons to AAA would result in a substitution of lysine for the original amino acid in each position.

This substitution could have various effects on the protein, depending on the specific sequence and function of the protein. For example, if the original amino acid was a hydrophobic residue and lysine is hydrophilic, it could result in changes in the protein's folding or interactions with other molecules. Additionally, if the first codon in the original sequence was a start codon, changing it to AAA could result in a different reading frame and a completely different protein being produced. Further analysis would be necessary to determine the exact effects of this change on the resulting protein.
When you change the first codon of each gene to AAA, you're altering the genetic code. The AAA codon specifically codes for the amino acid lysine. By changing the first codon to AAA, you're introducing lysine as the starting amino acid for each protein, which can significantly impact the protein's structure, function, and interactions. The new protein may have different properties or even become non-functional, depending on the significance of the original amino acid and its role in the protein's structure. This editing demonstrates the importance of specific codon sequences in determining protein characteristics.

To determine whether the lactase enzyme shows specificity, we can compare its activity on lactose and sucrose substrates. If the enzyme is specific to lactose, it should only break down lactose and not sucrose.

Based on the data collected in the lab, we can see that the lactase enzyme did show specificity. When lactose was used as a substrate, there was a significant increase in the rate of reaction compared to the control group where no lactase was added. In contrast, when sucrose was used as a substrate, there was no significant increase in the rate of reaction compared to the control group.

This indicates that the lactase enzyme is specific to lactose and is not able to break down sucrose. This specificity is due to the enzyme's unique shape and active site, which is optimized to bind and break down lactose but not other types of sugars.

Overall, the data supports the idea that the lactase enzyme shows specificity and is optimized to break down lactose.

Both the sympathetic and parasympathetic divisions of the autonomic nervous system are responsible for innervating the kidneys.

A highly innervated organ, the kidney. Both afferent and efferent fibers of the renal plexus are involved in kidney innervation. This plexus is made up of fibers that come from the celiac plexus. Each contributing plexus contributes to efferent innervation, which is mostly sympathetic. The kidneys are additionally innervated by parasympathetic fibers from the vagus nerve and fibers from the intermesenteric plexus.

The sympathetic route is followed by afferent fibers that transmit pain from the viscera. The sympathetic trunk is reached by way of the celiac plexus and the splanchnic nerves by the afferent fibers that sense pain coming from kidney stones in the renal pelvis or calyces.

Peptidoglycan is a vital component of the bacterial cell wall and plays a crucial role in maintaining the structural integrity and shape of bacterial cells. It is a polymer made up of alternating sugar molecules, N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM), cross-linked by short peptide chains.

Let's discuss the various aspects of peptidoglycan, including its structure, synthesis, and inhibition by antimicrobials.

1) Structure of Peptidoglycan: Peptidoglycan consists of long chains of NAG and NAM sugars, which are connected by glycosidic bonds. The NAM sugar has a peptide side chain attached to it. The peptide side chain typically consists of four to six amino acids, which can vary between bacterial species. These peptide chains serve as cross-links between the sugar chains, providing strength and rigidity to the cell wall. The cross-linking of peptidoglycan is crucial for maintaining the cell wall's integrity and protecting bacteria from osmotic pressure.

2) Synthesis of Peptidoglycan:

The synthesis of peptidoglycan occurs in several steps:

a. Formation of NAM and NAG: The precursor molecules NAM and NAG are synthesized in the cytoplasm from sugar nucleotide precursors.

b. Assembly of the sugar precursors: The NAM and NAG molecules are transported across the cytoplasmic membrane and attached to a lipid carrier molecule called undecaprenyl phosphate. This complex, known as lipid II, is flipped across the membrane to the outer surface.

c. Polymerization: The lipid II molecule on the outer surface serves as the building block for peptidoglycan synthesis. The NAM and NAG units from lipid II are transferred to the growing peptidoglycan chain, which is anchored to the inner surface of the cell membrane.

d. Cross-linking: The peptide side chains of adjacent sugar chains are cross-linked by enzymes called transpeptidases or penicillin-binding proteins (PBPs). These enzymes form peptide bonds between the amino acids, resulting in a three-dimensional network of peptidoglycan.

3) Inhibition by Antimicrobials: Peptidoglycan synthesis is an attractive target for antimicrobial agents because it is unique to bacteria and absent in eukaryotic cells. Several antimicrobial agents inhibit peptidoglycan synthesis through different mechanisms:

a. Beta-lactam antibiotics: This class includes penicillins, cephalosporins, and carbapenems. They target PBPs, which are responsible for cross-linking the peptidoglycan. Beta-lactam antibiotics bind to PBPs and inhibit their activity, leading to the weakening of the cell wall and cell lysis

b. Glycopeptide antibiotics: Examples include vancomycin and teicoplanin. They interfere with the late stages of peptidoglycan synthesis by binding to the peptide side chain of the growing peptidoglycan and preventing cross-linking.

c. Fosfomycin: This antibiotic inhibits the first step of peptidoglycan synthesis by blocking the enzyme responsible for the formation of NAG.

d. Bacitracin: Bacitracin interferes with the recycling of the lipid carrier molecule (undecaprenyl phosphate), preventing the assembly of NAM and NAG units into lipid II.

These antimicrobials disrupt peptidoglycan synthesis, leading to cell wall weakening, impaired bacterial growth, and ultimately, cell death.

In conclusion, peptidoglycan is a vital component
