The biological perspective examines psychological issues by investigating the scientific basis for animal and human actions. It is a major perspective in psychology that entails analyzing the brain, immune system, nervous system, and genetics. One of the long-running debates in psychology has been about the relative impact of nature versus nurture. Those on the nurture side of the issue contend that the environment has the greatest influence on behavior. The biological perspective emphasizes the value of nature.
The biological perspective is fundamentally a way of viewing human problems and actions. Since its inception, the survey of physiology and biochemical functions has played an important role in psychology.

Explain the limitation binomial nominclature (15 marks)
Answer:
- Binomial nomenclature is a widely accepted naming system, which is used in the naming of living things. Multiple native names make it extraordinarily tough to establish an organism globally and maintain an observation of the variety of species. Thus, it creates quite a lot of confusion. To eliminate this confusion, a normal protocol came up. According to it, every organism would have one scientific title which might be utilized by everybody to establish an organism.
What is binomial nomenclature?
Binomial Nomenclature follows a universally accepted naming system, which is used to provide a scientific name to a known organism.
Binomial Nomenclature also known as the binary nomenclature.
It uses two-terms during the nomenclature of a specie (plants, animals, and living organisms) that is why it called two-term naming system.
The scientific name of an organism or binomial nomenclature consists of two words, such as the generic epithet and describes the genus and the specific epithet and refers to the species of the organism.
Both of this term is written in italic and the genus name is capitalized.
Binomial nomenclature was given by Swedish botanist and physician Carl Linnaeus. He also called the founder of modern taxonomy.
Carl Linnaeus described and classified thousands of species of plants and animals in his book Systema Naturae.In this technique, there are particular guidelines that are followed while naming organisms. This normal algorithm is relevant to plants and animals whereas giving them distinctive names inside a given system.There are two worldwide codes such as the International Code of Botanical Nomenclature (ICBN) deal with the biological nomenclature for plants and the International Code of Zoological Nomenclature (ICZN) deal with the biological nomenclature of animals.
These two codes agreed upon by all of the biologists over the world for the naming protocol. These codes ensure that every organism will get a selected identity and that identity is globally recognized.
Summary of the limitation binomial nominclature:
- Some of the main drawbacks of binomial nomenclature are: If two or more names are actually in use in compliance with the priority rule, the appropriate name will be used first and the other names will end up being synonyms because authenticity is synonymous with the senior.

Explanation:
What feature about water gives it such unique properties?
Its polarity and bond angle
Water being made up of oxygen and hydrogen
Water being able to dissolve substances
Water being in all cells
Its polarity and bond angle makes water unique properties.
The structure of water molecules is twisted and polar, with partial positive charges on the hydrogens and partial negative charges on the oxygen. This is because oxygen attracts electrons more effectively than hydrogen since it is more electronegative. A great solvent is a water.
Cohesion in water is caused by its polarity. The forces that induce or permit similar molecules to stick together are referred to as cohesion. Water has cohesiveness because its molecules naturally desire to adhere to one another.
When water is not boiling into a gas or freezing into a solid, it is in a liquid condition. When it is liquid, water has the lowest density.

In a dihybrid cross between two pea plants, one parent is green pod-purple flower (GgPp). The other parent’s genotype is unknown. The phenotype f ratio of their offspring is (1 Green Pod-Purple Flower : 1 Yellow Pod-Purple Flower). What is the genotype of the unknown parent?
The unknown parent's genotype in the dihybrid cross is likely GgPp. This genotype would result in a 1:1 phenotypic ratio of green pod-purple flower to yellow pod-purple flower offspring.
In a dihybrid cross, we consider two independent traits. In this case, the traits are pod color (green or yellow) and flower color (purple). The known parent's genotype is GgPp, where G represents the dominant allele for green pod color, g represents the recessive allele for yellow pod color, P represents the dominant allele for purple flower color, and p represents the recessive allele for non-purple (white) flower color.
Since the phenotypic ratio of the offspring is 1 green pod-purple flower : 1 yellow pod-purple flower, we can infer the possible genotypes of the unknown parent. The observed phenotypic ratio suggests that both parents contribute equally to the offspring's traits. Therefore, the unknown parent likely carries the same genotype, GgPp.When the unknown parent's genotype is GgPp, it means that it can produce two types of gametes: GP and gP. The known parent, GgPp, can also produce two types of gametes: GP and gP. The cross between these parents can result in four possible genotypes for the offspring: GGPp, GgPp, Ggpp, and ggPp. However, only two of these genotypes correspond to the observed phenotypic ratio: GgPp (green pod-purple flower) and ggPp (yellow pod-purple flower).Therefore, the genotype of the unknown parent is likely GgPp, which produces the desired 1:1 phenotypic ratio of green pod-purple flower to yellow pod-purple flower in the offspring.

The topic is the invasive species “Kudzu” My practice for us to review is in the pic, answer these in a short summary
Kudzu is an invasive species brought from regional areas around the Pacific. It was brought over as decoration and farming purposes, unknown to the farmers that it was an invasive species. Kudzu is a type of vine that grows over plants and trees and occupies a large area.
Kudzu is known as an invasive species because it grows over primary producers, aka trees, grass, and plants. When Kudzu grows, it envelops the primary producer underneath it, causing it to have limited access to sunlight, a vital energy source for primary producers. Without the sun, these primary prouccers like plants and grass cannot produce the food necessary to support an ecosystem.
We can recall that primary producers are the most abundant species in an ecosystem. They are also a keystone species - if primary producers are removed, the entire ecosystem will be disrupted, as there is no food source for primary consumers. This in turn creates a shortage of food for secondary consumers, etc.
Relating this back to Kudzu, this vine species kills and displaces the primary producers in any ecosystem, causing the primary producers to limited in numbers. Animals such as deer (primary consumers) who rely on primary producers such as grass as their main food source will not have enough energy to survive (food-energy transfer). This, in turn, will affect secondary consumers such as coyotes who prey on deer as their food source. The tertiary consumer, in our example we can use wolves, who hunt on coyotes as a food source, will also struggle to find a sustainable food source, since the number of coyotes is smaller.
Therefore, Kudzu, an invasive species, creates a chain effect (or snowball effect) that causes devastating consequences to an ecosystem.
What is the constant cycling of carbon between living organisms and their environment called?.
The constant cycling of carbon between living organisms and their environment is called the Carbon Cycle.
Carbon is a key component of life, and it is found in molecules like carbon dioxide, which is essential for plants and other organisms to convert into energy through photosynthesis. Additionally, carbon is found in other molecules like proteins, lipids, and carbohydrates, and is exchanged between living and non-living organisms. The Carbon Cycle involves photosynthesis and respiration in which carbon dioxide is taken up by plants and converted into organic compounds, and then released back into the atmosphere through respiration by animals and decomposition of organic matter.
Additionally, the Carbon Cycle is also affected by human activities, like the burning of fossil fuels and deforestation, which add carbon dioxide to the atmosphere and reduce its ability to absorb the gas.

If you added 1 ml of an aqueous solution of NaCl at 0.4 mol/l to 9 ml of water, what would be the final concentration of NaCl in the solution?
Taking into account the definition of dilution, the final concentration of NaCl in the solution is 0.04 mol/L.
DilutionWhen it is desired to prepare a less concentrated solution from a more concentrated one, it is called dilution.
Dilution is the process of reducing the concentration of solute in solution, which is accomplished by simply adding more solvent to the solution at the same amount of solute.
In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, as the volume (and weight) of the solution increases.
A dilution is mathematically expressed as:
Ci×Vi = Cf×Vf
where
Ci: initial concentrationVi: initial volumeCf: final concentrationVf: final volumeFinal concentrationIn this case, you know:
Ci= 0.4 mol/LVi= 1 mLCf= ?Vf= 1 mL of aqueous solution of NaCl + 9 mL of water= 10 mL solutionReplacing in the definition of dilution:
0.4 mol/L × 1 mL= Cf× 10 mL
Solving:
(0.4 mol/L × 1 mL)÷ 10 mL= Cf
0.04 mol/L= Vf
In summary, the final concentration of NaCl in the solution is 0.04 mol/L.
