The system of classification, first developed by Linnaeus in the 1700's, which is now used by biologists and paleontologists has modern humans and their near relation in the Genus Homo.

The genus Homo is a taxonomic classification that includes modern humans (Homo sapiens) and several extinct species that are closely related to humans. It is part of the family Hominidae, which also includes great apes such as chimpanzees, bonobos, gorillas, and orangutans. The genus Homo is characterized by certain distinctive traits that separate it from other hominin species. These traits include an upright bipedal posture, a larger brain size relative to body size, reduced facial and dental features, and the ability to create and use complex tools.

The earliest known species in the genus Homo is Homo habilis, which lived approximately 2.4 to 1.4 million years ago. Homo habilis is considered one of the earliest tool-makers and was likely capable of simple stone tool production. Another significant species is Homo erectus, which existed from around 1.9 million to 143,000 years ago. Homo erectus had a larger brain size and more advanced tool-making abilities than earlier hominin species.

Answer:

Hello the answer is in explanantion

Explanation:

Global temperature records: Over the past century, global temperature records show that the average temperature of the Earth's surface has increased by about 1 degree Celsius (1.8 degrees Fahrenheit). This may not sound like a lot, but it is a significant change in the context of the Earth's climate history.

Melting glaciers and ice caps: Glaciers and ice caps are melting at an unprecedented rate in many parts of the world. For example, the Greenland ice sheet, which is the second-largest ice sheet in the world, is losing an estimated 260 billion tons of ice per year. This melting has led to rising sea levels, which threaten to flood coastal communities and low-lying islands. The melting of glaciers and ice caps is also disrupting ecosystems and water supplies in many regions.

Cellular respiration describes the process of oxygen and glucose and converting into water and carbon dioxide. Homeostasis is a term which refers to biological processes in which living things must maintain stable and equal conditions for survival. Cellular respiration which uses oxygen and glucose must be able to sustain life by releasing energy which is called ATP, the ATP which is produced enables many biological processes that keeps organisms alive. Cells need energy to grow, move, and function. The process of homeostasis enables cellular respiration to produce enough molecules which can sustain the development of the cell. Without homeostasis cellular respiration would cease to function and without cellular respiration the process of homeostasis would not occur. Homeostasis regulates how much molecules have to be expended in order to produce energy for the process of cellular respiration.

According to Chargaff's rule, if a DNA strand has 30% guanine before to semi-conservative replication, the  percentage of thymine that will have each new strand after replication will be 20% (option A).

Explanation:

A DNA molecule stores the genome of a living organism in a specific sequence of its nitrogenous bases adenine, guanine, cytosine and thymine. By knowing the percentage of a nitrogenous base in the DNA, the percentage of the other bases can be established using Chargaff's base pair rule.

Chargaff was able to establish that in a DNA molecule the ratio purine:pyrimidine is 1:1, so there must be the same amount of guanine as cytosine and a similar amount of adenine for thymine, taking into account the complementarity of the bases.

According to the base pair rule, if in a DNA strand there is 30% guanine, in the molecule there is:

In this case, Chargaff's rule is useful to determine the percentage of thymine that each new strand will have after replication, corresponding to 20%.

The development of resistant strains of bacteria like TB, Malaria, and Gonorrhea is due to the use of antibiotics.

The overuse and misuse of antibiotics are among the reasons for the development of resistant strains of bacteria. Antibiotics destroy or inhibit the growth of bacteria, but overusing them, or using them when they're not necessary, can make them less effective.

Inappropriate prescriptions, the use of antibiotics in livestock and fish, and the use of antibiotics in the environment can all contribute to antibiotic resistance. The repeated exposure to a specific antibiotic also encourages the development of resistant bacteria.

That is why antibiotic prescriptions should always be taken as prescribed, and only for bacterial infections, not for viral infections, such as colds or flu. The emergence of resistant strains of bacteria can result in higher morbidity, mortality, and healthcare costs, as well as the need for more expensive or toxic antibiotics.

After transcription, mRNA goes through a process called splicing in which introns are removed and thrown away, leaving only exons. Therefore, option c is the right response: exons are left after introns have been removed and discarded.

Introns, which are non-coding DNA segments, are excised from the pre-mRNA transcript during the splicing process, which takes place in the nucleus of eukaryotic cells after transcription.

The mature mRNA molecule is created by joining the leftover exons, which contain the protein-coding sequence. The spliceosome, a massive assembly of proteins and RNA molecules, aids in this process.

The creation of a functional mRNA molecule, which can then be translated into a protein by the ribosome, depends on the removal of introns and the joining of exons.

In eukaryotic cells, splicing is a key process for controlling gene expression and producing a variety of proteins.

The frequency of resistant cells in a population of bacteria can be changed by factors such as mutation, migration, and plasmids. Among the options provided, option 6 - "Plasmids, mutation, and migration" best explains the combination of factors that can influence the frequency of resistant cells.

Mutation can lead to the development of new resistant alleles, allowing bacteria to become resistant to certain substances or antibiotics. Migration refers to the movement of resistant cells into or out of a bacterial population, which can alter the overall frequency of resistant cells. Plasmids are small, circular DNA molecules that can be transferred from one bacterial cell to another, potentially spreading resistance genes among the population.

In summary, the frequency of resistant cells in a population of bacteria can be influenced by plasmids, mutation, and migration, all of which play a role in shaping the resistance traits observed in the bacterial population.

The relationship between metabolites and DNA is indirect but crucial for the proper functioning of the cell.

Metabolites are small molecules that are involved in metabolic pathways and contribute to the overall cellular function. They are not directly encoded by DNA, but their production is catalyzed by enzymes, which are proteins that are encoded by DNA. These enzymes are responsible for converting one metabolite into another, which enables the cell to carry out various biological processes. While metabolites are not responsible for storing genetic information like DNA, they do interact with nucleic acids, which include DNA and RNA. Nucleic acids are the macromolecules that are responsible for encoding genetic information and controlling cellular processes. Additionally, proteins, which are made up of amino acids and are encoded by DNA, play an important role in the metabolism of various metabolites. Ribosomes, which are molecular machines made up of RNA and proteins, translate the genetic information encoded in RNA to produce proteins, which then catalyze the production of metabolites. Therefore, the relationship between metabolites and DNA is indirect but crucial for the proper functioning of the cell.

Homozygous dominant, heterozygous, and homozygous recessive genotypic frequencies are 36%, 48%, and 16%, respectively:

Here: homozygous dominant genotype, AA

Aa for the genotype of heterozygotes

Homozygous recessive genotype for aa, 16 out of the 100 people in the population have the recessive trait, hence there are 16 in the population. Thus, the genotype frequency for aa is 16/100, or 0.16.

The frequency of the A allele plus the frequency of the an allele must equal one because there are only two potential alleles at this locus (A and a). This fact, along with the frequency of the aa genotype, can be used to determine how common the A allele and the aa genotype are:

frequency of aa genotype = q² = 0.16,

frequency of A allele = p = 1 - q

frequency of Aa genotype = 2pq,

q = 0.16 = 0.4

p = 1 - q = 0.6

frequency of Aa genotype = 2pq = 2(0.6)(0.4) = 0.48

frequency of AA genotype = p² = (0.6)² = 0.36

Therefore, the genotypic frequencies are:

AA: 0.36 or 36%

Aa: 0.48 or 48%

aa: 0.16 or 16%

Urban runoff is a major environmental threat to habitats and ecosystems and is closely linked to the world's growing urban population. Therefore, the correct option is C.

As cities grow and urban areas mature, more impermeable surfaces such as highways, parking lots and buildings are exposed. Because of these surfaces, water cannot be absorbed by the soil, leading to excessive rainfall and storm water runoff.

Urban runoff carries contaminants such as oil, chemicals, heavy metals and garbage from roads and urban areas into neighboring water bodies, such as rivers, lakes and seas. This pollution has the potential to damage aquatic ecosystems, contaminate drinking water supplies, and disturb the balance of the aquatic environment.

Therefore, the correct option is C.

The relationship between fig wasps and fig trees is one of the best examples of coevolution due to the strong reciprocal relationship between the two species.

Fig wasps are the only species capable of pollinating the flowers of fig trees, and in turn the trees provide a habitat for the wasps to lay their eggs and reproduce. This interdependent relationship is a perfect example of coevolution.

Over time, the two species have developed specific adaptations to ensure the continued survival of each other. For example, the wasps have evolved to be able to enter the tiny openings of the fig tree's flowers, and the trees have evolved to produce small flowers that only the wasps can enter.
