how to ecosystem services affect human sustainability

Answer:

The diversity within the same species is what makes it not possible to reproduce, since it can have different methods of appearance and even different zones or mechanisms of reproduction since this was adapted to each particular climax.

Explanation:

Frogs that have different qualities in the same species are because they are subject to different environmental characteristics, therefore it is a way of natural adaptation.

By having different adaptation methods, this conditions that there is no cross reproduction between them.

Burning, pulping, as well as shredding are the three ways which are used to securely dispose of data in the paper form.

When we destroy data, the main goal is to make the data completely unreadable which is regardless of the form of the electronic media on which the data is originally stored. The process of the data destruction also includes ensuring the fact this data cannot be recovered again or used for any unauthorized purposes.

Merely deleting a particular file is insufficient. When we delete a file on a particular electronic device, we may not be able to see it any longer, but the information can still be found on the device’s hard drive. Physically, when we destroy paper, we can do that by pulping, burning and shredding.

Explanation:

The phenotype that will allow them to identify cells that have been complemented is the restoration of leucine and tryptophan prototrophy.

An auxotroph is a strain that requires specific nutrients or growth factors to be supplemented in the growth medium because it is unable to synthesize them. In this case, the yeast strain is a leucine and tryptophan auxotroph, meaning it cannot synthesize leucine and tryptophan on its own.

After the mutation caused by the chemical mutagen, the mutant yeast cells experience a defect in mRNA export at elevated temperatures. This defect leads to a disruption in the normal cellular processes and can result in impaired growth or survival of the cells under specific conditions, such as elevated temperatures.

To identify cells that have been complemented, the researchers introduce plasmids containing the genes of interest into the mutant yeast cells. The genes of interest are likely the ones responsible for restoring the defective mRNA export and allowing normal cellular functions to resume.

If the introduced plasmids containing the genes of interest successfully complement the mutant phenotype, the researchers will observe the restoration of leucine and tryptophan prototrophy in the cells. This means that the mutant cells, which were previously unable to synthesize leucine and tryptophan, will regain the ability to produce these amino acids on their own.

By monitoring the growth of the yeast cells on a selective growth medium lacking leucine and tryptophan, the researchers can identify the cells that have been complemented. The complemented cells will be able to grow on the selective medium without the need for supplemental leucine and tryptophan, indicating a restoration of the prototrophic phenotype.

In summary, the phenotype that will allow the identification of cells that have been complemented in the mutant yeast strain is the restoration of leucine and tryptophan prototrophy, indicating successful complementation of the mutant phenotype.

The presence of cell wall in plants which is absent in the animals cells is what allows the withstanding of the internal pressure during the expansion of the central vacuole.

The plant cell basically contains an outer cell which is made up of pectin as well as cellulose. It gives the plant cell its shape as well as rigidity. This cell wall is absent in the case of the animal cell and their cell only has a cell membrane.

The plants also have a centrally placed vacuole which is big in size. This vacuole plays an important role facilitating the growth of the cells and absorbs water inside it. Even though this happens, the cell is able to withstand the internal pressure due to the presence of the cell wall.

In human blood typing, there are three alleles that code for A, B, and O phenotypes. A and B are codominant, while O is recessive.

The statement describes the three alleles involved in human blood typing.

The ABO blood group system is determined by the presence or absence of three alleles: A, B, and O. The A and B alleles are codominant, meaning that if an individual inherits both A and B alleles, both antigens will be expressed on their red blood cells.

This results in the AB blood type. The O allele is recessive, and individuals with the O allele do not produce A or B antigens, resulting in the O blood type.

The ABO blood group system is important for blood transfusions and compatibility. Individuals with type A blood have A antigens, type B blood have B antigens, type AB blood have both A and B antigens, and type O blood have neither A nor B antigens.

Understanding the inheritance patterns of these alleles helps determine blood compatibility and minimize the risk of transfusion reactions.

During prophase, the parent cell will have 48 chromatids. This is because during interphase, the DNA replicates, resulting in each chromosome consisting of two sister chromatids.

Therefore, if the parent cell has 24 chromosomes, it will have a total of 48 chromatids during prophase.

Regarding the major difference between plant cells and animal cells, the most accurate statement is: "Only plant cells have a cell wall." Plant cells have a rigid cell wall made of cellulose, which provides structural support and protection to the cell. Animal cells, on the other hand, do not have a cell wall.

Answer: The VILLI (increase surface area in the small intestine).

Explanation:

Glucose, amino acids, fatty acids and glycerol, as well as , vitamins and minerals salts are absorbed in the small intestine. The walls of small intestine are specially adapted to carry out this function.

For efficient adsorption, a large surface area is necessary. The walls of small intestine have folds and furrows which serve to increase its surface area. These small finger-like projections are called the VILLI.

The inner surface layer or epithelium of each villus is thin; this allows the absorption of the end-products by either diffusion or active transport through it. There is a rich supply of blood vessels and lymphatic vessels containing blood and lymph respectively to carry away the absorbed food substances. In each villus( singular) , there is a blind lymphatic tube called a lacteal surrounded by a network of blood capillaries. The lymph in the lacteals transports carboxylic acids and glycerol which usually recombine to form fats again in the lacteals.

A plant dies if it’s pholem tissue is removed. Why?

When the phloem is removed, no substance is transported, the plant does not have the necessary requirements to carry out the process (photosynthesis), and finally the plant dies.

The three-dimensional structure of proteins plays a fundamental role in their versatility and ability to perform diverse functions in living organisms.

Proteins indeed have a three-dimensional structure that is essential for their functionality in living organisms. This structure is determined by the arrangement of amino acids in the protein chain and is organized at multiple levels: primary, secondary, tertiary, and in some cases, quaternary.

The primary structure refers to the linear sequence of amino acids in the protein. This sequence is encoded by the DNA and RNA molecules. The specific sequence of amino acids dictates how the protein will fold and ultimately determine its shape.

The secondary structure involves local folding patterns within the protein chain, typically forming either alpha-helices or beta-sheets. These structures are stabilized by hydrogen bonding between amino acid residues.

The tertiary structure describes the overall three-dimensional folding of the protein. It results from interactions between amino acid side chains, such as hydrophobic interactions, hydrogen bonding, ionic interactions, and disulfide bonds. The tertiary structure is critical for the protein's stability and function.

In some cases, proteins can have a quaternary structure, which arises when multiple protein subunits come together to form a functional complex. This structure is important for proteins that require multiple subunits to carry out their functions.

The specific three-dimensional structure of a protein is crucial for its function. It determines how the protein interacts with other molecules, such as enzymes, receptors, or DNA, allowing it to carry out various biological processes. Any alteration in the protein's structure can lead to loss of function or dysfunction, potentially causing diseases or impairing cellular processes.

Overall, the three-dimensional structure of proteins plays a fundamental role in their versatility and ability to perform diverse functions in living organisms.

DNA Replication:

Replicate the following strand of DNA:

Original DNA: A T G A A C CA T T C A G T A T G G

Complementary DNA:

Remember that the complimentary base pairs in DNA are Adenine-Thymine and Guanine-Cytosine, or A-T and G-C. This means that if the original sequence is:

A T G A A C C A T T C A G T A T G G

Then the compliment is (replace with the opposite base pairs):

T A C T T G G T A A G T C A T A C C

Transcription:

Transcribe the DNA to make an mRNA molecule

COMPLIMENTARY DNA:

mRNA Molecule:

So if our complimentary DNA (antisense stand) is T A C T T G G T A A G T C A T A C C then to transcribe, we basically create another complimentary strand, but for mRNA, we use Uracil instead of Thymine:

A U G A A C C A U U C A G U A U G G  

Translation:

Translate the mRNA into the corresponding amino acids.

mRNA MOLECULE:

AMINO ACID:

Using the DNA sequence provided, determine the amino acids.

Next, take each codon (3-base set) to the table and record the corresponding protein:

A U G = Methionine (start)

A A C = Asparagine

C A U = Histidine

U C A = Serine

G U A = Valine

U G G = Tryptophan

ORIGINAL DNA: A T G G G T C T A G C G A A A G A T

Complementary DNA:

mRNA DNA Molecule:

Amino Acid:

And we do it all again:

A T G G G T C T A G C G A A A G A T = original DNA

T A C C C A G A T C G C T T T C T A = complementry DNA

A U G G G U C U A G C G A A A G A U = mRNA

A U G = Methionine (start)

G G U = Glysine

C U A = Leucine

G C G = Alanine

A A A = Lysine

The sequence of RNA codons resulting from the substitution mutation that changed the 5th base in the DNA from a C to a T is AUGUGCGUUAUCCAGGGUAGCCAAUUGA.

In DNA, the base C (cytosine) pairs with G (guanine), while in RNA, the base C pairs with G. However, due to the substitution mutation, the original C is replaced by a T (thymine) in the DNA sequence.

In RNA, thymine is replaced by uracil (U). Therefore, the RNA codons corresponding to the mutated DNA sequence can be derived by replacing each T with U and maintaining the sequence order.

The original DNA sequence TACACGCAATTACCAGGGTAGCCATTGATT would have the corresponding RNA codons AUGUGCGUUAUCCAGGGUAGCCAAUUGA. Each codon consists of three bases and represents a specific amino acid or a start or stop signal in the translation process of protein synthesis.
