The nitrogen cycle is important to humans in the following way: it converts nitrogen into a form that humans can obtain by eating other organisms (option B).

Nitrogen cycle is the natural circulation of nitrogen in a series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition.

During the nitrogen cycle, atmospheric nitrogen is converted to nitrogen oxides by lightning and deposited in the soil by rain, where it is assimilated by plants and either eaten by animals (and returned as faeces) or decomposed back to elemental nitrogen by bacteria.

The usable form of nitrogen that is assimilated by plants becomes accessible to humans when they consume the plants, hence, depicting the importance of the nitrogen cycle.

Answer:

Explanation:

The longest-lived animal ever discovered is a quahog clam, estimated to be 507 years old.

Answer:

Valine-Leucine-Proline-Lysine-Histidine

Explanation:

The central dogma of biology is the process by which DNA is used to synthesize RNA and subsequently amino acid sequence (PROTEIN). The processes of transcription and translation is used in gene expression. Transcription is the process whereby the information encoded in a DNA molecule is used to synthesize a mRNA molecule. Transcription is catalyzed by RNA polymerase enzyme, which uses complementary base pairing rule i.e Adenine(A)-Thymine(T), Guanine(G)-Cytosine(C) pairing.

N.B: Thymine is replaced by Uracil in the mRNA

For the above DNA sequence: CAC GAC GGA TTC GTA, the mRNA sequence will be: GUG CUG CCU AAG CAU

Translation is the second process of gene expression which involves the synthesis of an amino acid sequence from an mRNA molecule. The mRNA is read in a group of three nucleotides called CODON. Each codon specifies an amino acid (see attached image for genetic code)

Based on the attached genetic code, an mRNA sequence: GUG CUG CCU AAG CAU will encode an amino acid sequence: Valine(Val) - Leucine (Leu) -Proline (Pro) -Lysine (Lys) - Histidine (His).

GUG specifies Valine amino acid

CUG specifies Leucine amino acid

CCU specifies Proline amino acid

AAG specifies Lysine amino acid

CAU specifies Histidine amino acid

When The central dogma generates the amino acid sequence that results from this sequence is: Valine-Leucine-Proline-Lysine-Histidine

When The central dogma of biology is the process by which DNA is used to synthesize RNA and also subsequently amino acid sequence (PROTEIN). Then The processes of transcription and also translation is used in gene expression. Transcription is the process whereby the transmission encoded in a DNA molecule is useful to synthesize an mRNA molecule. Transcription is catalyzed by RNA polymerase enzyme, which operates complementary base pairing rule i.e Adenine(A)-Thymine(T), Guanine(G)-Cytosine(C) pairing.

Then, N.B: Thymine is replaced by Uracil in the mRNA

After that, For the above DNA sequence: CAC GAC GGA TTC GTA, the mRNA sequence will be: GUG CUG CCU AAG CAU

The translation is the second procedure of gene expression which

implicates the synthesis of an amino acid sequence from an mRNA molecule. When The mRNA is read in a group of three nucleotides called CODON. Individually codon identifies an amino acid (see attached image for genetic code)

Established on the connected genetic code, an mRNA sequence: GUG CUG CCU AAG CAU will encode an amino acid succession: Valine(Val) - Leucine (Leu) -Proline (Pro) -Lysine (Lys) - Histidine (His).

Then, GUG specifies Valine amino acid

Now, CUG specifies Leucine amino acid

Explanation: The discovery of mitochondrial DNA (mtDNA) had no effect on the study of cork bark.

Most articles pass right through the atom, this means that most of the atom is an empty space.

An atom is described as a particle that consists of a nucleus of protons and neutrons surrounded by a cloud of electrons.

Protons and neutrons make up the core nucleus of an atom, which is encircled by an electron cloud. In relation to the size of the atom as a whole, the nucleus is exceedingly small.

As a result, the electrons surrounding the nucleus are the primary target of interactions when particles or even light pass through an atom. The majority of the atom's remaining space, which includes the nucleus, is vacant.

Answer:

Geographical isolation

Explanation:

The evolutionary mechanism that can probably explain the difference, in this case, is geographical isolation.

Geographical isolation represents one of the reproductive isolation mechanisms - an array of physiological and behavioural processes that leads to speciation in living organisms.

Geographical isolation refers to the separation of organisms of the same species in terms of physical geographical features such as distance, mountains, water bodies, etc. The separation causes each group to take different adaptive paths, eventually leading to speciation, that is, they become separate species.

In this case, the small population of monkeys in the isolated forest must have been geographically isolated from their counterparts in some ways back. They took a different adaptive path from the larger group as a result of geographical difference and eventually became a new species.

1.The motivations and drivers behind Paleolithic artists creating sculptures are not explicitly documented, as there are no written records from that time.

2.The Egyptian canon of proportions refers to the artistic guidelines followed by ancient Egyptian artists to depict human figures in a consistent and standardized manner.

3.The term "Spear Bearer" typically refers to the sculpture known as the "Doryphoros" or "Spear Bearer" by the ancient Greek sculptor Polykleitos.

4.Polykleitos, an ancient Greek sculptor from the 5th century BCE, developed a canon of proportions known as the "Doryphoros Canon" or "Canon of Polykleitos."

1.However, it is believed that the artists were inspired by their surroundings, natural forms, and possibly spiritual or religious beliefs. Some theories suggest that the sculptures had ritualistic or symbolic purposes, representing fertility, hunting, or ancestral figures. Others propose that they were created for personal expression or as a means of communication within the community.

2.It involved specific ratios and proportions that governed the idealized representations of the human body in Egyptian art. The canon typically depicted figures with the head, torso, and legs in a frontal view, while the arms and feet were shown in a more stylized, composite view. The proportions emphasized symmetry, rigid postures, and hierarchical scaling, reflecting the social and religious values of the Egyptian civilization.

3. This sculpture is believed to have been created in the 5th century BCE and is known primarily through Roman copies. It represented a male athlete holding a spear in a contrapposto stance, with balanced and harmonious proportions. The primary sources available regarding the Spear Bearer would include writings from ancient historians, descriptions in art catalogs, and any other documents that discuss the sculpture.

4.This canon aimed to establish an idealized representation of the male figure. Polykleitos believed that harmony and beauty in sculpture could be achieved through mathematical ratios and proportions. His canon emphasized the idea of symmetria, or balance, in the human body. The proportions were based on the concept of the "perfect" or "ideal" male figure, with mathematical ratios determining the relationships between various body parts. The canon aimed to achieve a sense of naturalistic realism while still adhering to the idealized proportions defined by Polykleitos.

Answer:

Two heterozygous parents have a 50% chance of contributing one of their alleles to each offspring.

Explanation:

Individuals who are heterozygous for a specific trait have two different alleles in the gene that determines that trait. This characteristic makes their chances of contributing each of their alleles to the offspring 50%.

The alleles of a gene are distributed in the gametes by the process of meiosis, which results in daughter cells with half the genetic charge, so each gamete can only have one copy of the allelic pair of a gene.  

On the other hand, if an individual has two equal alleles for a characteristic in a gene, he has a 100% chance of passing that allele on to his descendants.

The organism has different types of Connective tissues providing support and connectin to organs and other structures. 1) Connective tissue. 2) Dense irregular connective tissue.

The connective tissue, also known as support tissue, supports and connects all the other tissues and organs in the body. Every substance exchange between epitheliums, muscles, nerves, and the vascular system must be done with the connective tissue as an intermediate.

According to its specialization, there are different kinds of connective tissue, such as cartilage, blood, bony tissue, or lymphatic tissue, among others. Each type of connective tissue has its own cell type according to its functions. Cellular types, fibers, and aqueous medium appear in different amounts in different parts of the organism.

The connective tissue is composed of cells that are very separated from each other because of the abundant extracellular matrix, which is produced by fibroblasts, a predominant cell population. The extracellular matrix has fibrillar proteins of different natures such as collagen, fibrillin, and elastin that determine tension properties.  There are also adessive proteins such as fibronectin and laminin. All of these proteins are included in a medium that contains water, salts, GAGs, proteoglycans, glycoproteins, and other macromolecules that confer turgidity and facilitate diffusion. The properties of this matrix in different connective tissues mark the difference between each other.

The connective tissue originates in the mesoderm, which in the early stages of development, differentiates from an embryonary connective tissue called mesenchyme.

Answer:

The most probable location on the chromosome of each gene is:

wing shape gene ------- eye color gene -------- body color gene

Explanation:

To know if two genes are linked, we must observe the progeny distribution. In a tri-hybrid cross, If individuals, whos genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1:1:1:1:1. If we observe a different distribution, that is that phenotypes appear in different proportions, we can assume that genes are linked in the heterozygote parent.

We can recognize the parental gametes in the descendants because their phenotypes are the most frequent, while the double recombinants are the less frequent. And simple recombinant gametes produced by the cross, which frequencies are intermediate.  

By comparing the parental and the double recombinant we will realize which is the allele that changes in position. The position of this gene is in the middle of the other two genes because in a double recombinant only the central gene changes position in the chromatid.

So, according to this knowledge and the available information in the problem we can estimate the position of the genes in the chromosome.

Phenotypic proportions:

90% of individuals are red-eyed and curly-winged. This is a high frequency, which means that this is the parental phenotype. The other parental phenotype must be white eyes and straight wings.

Flies with curly wings, white eyes, and black bodies represent the lower proportion (1%) so this phenotype must be the double recombinant.

Flies with red eyes and black bodies, and flyes with red eyes and brown bodies are intermediate in proportion, so they must be simple recombinant phenotypes.

Parental)

Red, Curly  

White, Straight

Double recombinant)

White, Curly, Black  

Red, Straight, Brown  

Simple recombinant)  

Red, Black

Red, Brown

In the chromatid, there are two regions, Region 1 (from the first gene to the gene in the middle), and region 2 (from the gene in the middle to the gene of the other extreme).

The fact that both simple recombinants are red, tells us that the eye color gene and the body color gene are together, and the recombination occurred either in region 1 or 2.  

We know that the double recombinant is White, Curly, Black. We also know that the eye color gene and the body color gene are together, so one of these two must be in the middle.

Parentals are red and curly, which means that the eye color gene and wing shape gene are also together. This leads us to assume that the eye color gene is in the middle.

Finally, the fact that the double recombinant is White, Curly, Black, and knowing that the eye color is in the middle and that both the extreme alleles change position, we can assume that the parental Red, Curly is also black, while the other parental is white, straight and brown. So:

Curly ------ Red ------Black (90%)

Straight ----- White ----- Brown

Curly -----White-----Brown

Straight-----Red -----Black (75%)

Curly----Red-----Brown (25%)

Straight ----White-----Black

Curly-----White------Black (1%)

Straight----Red------Brown
