An idea or belief that is developed by a group of people and is not inherently
true or scientifically proven is considered to be constructed socially.
An idea or belief that is developed by a group of people and is not inherently true or scientifically proven is considered to be constructed Socially i.e. Social racism.
what is social racism?Social racism is the formalization of a set of institutional, historical, cultural and interpersonal behaviors within a society. Social Racism disadvantages one or more social or ethnic groups and places them in a better position to succeed, resulting in long-term inequities between the groups. Scientists generally believe that race is a social construct without biological significance. For example, DuBois would be favored by science. Scientists nowadays believe that race is a sociological construct with no biological significance. Even yet, you might discover categories like white and black being utilized as biological variables in a genetics study published in a major scientific publication.
Hence , the correct option is D.

A. the amount of drug needed to achieve the same effect is increased as the substrate concentration increases.
B. the amount of drug needed to achieve the same effect is increased as the substrate concentration decreases.
C. substrate must be bound to the enzyme before the drug can bind.
D. the enzymes have to be allosterically regulated.
Answers
Answer: A. the amount of drug needed to achieve the same effect is increased as the substrate concentration increases
Explanation:
Competitive inhibition is when identical molecules to the substrate molecules gets bonded to the active site which then hinders the binding of the actual substrate. An example of competitive inhibitor is penicillin, since it blocks an enzymes active site which us used in the construction of the bacteria cell.
Then, the correct statement will be:
"Many drugs are competitive inhibitors of specific enzymes. In such cases, then the amount of drug that'll be needed to achieve the same effect is increased when the substrate concentration increases".
Therefore, the correct option is A.

Throughout human existence we have relied on the oceans – for food, as a waste dump, for recreation, for economic opportunities and so on. However, it’s not only our activities in the marine environment that affect life in the sea – it’s also the things we do on land.
With more than half the world’s population now living within 100 kilometres of the coast, it’s not surprising that our activities are taking their toll. Human impacts have increased along with our rapid population growth, substantial developments in technology and significant changes in land use. Over-fishing, pollution and introduced species are affecting life in the sea – and New Zealand is no exception!
Threats to marine habitats
Human actions at sea and on land are putting increasing pressure on the ocean and the species that live there.
Fisheries
Humans living near the coast have probably always used the ocean as a source of food. However, with advances in fishing equipment, larger ships and new tracking technologies, many fish stocks around the world have reduced significantly. Fish stocks on continental shelf areas are now widely considered to be fully or over exploited. Aside from reducing fish stocks, unsustainable fishing practices can have other negative impacts on the marine environment. For example, some fishing techniques such as dredging and trawling can cause widespread damage to marine habitats and organisms living on the sea floor. These techniques also often capture non-target species (known as bycatch) that are then discarded.

Commercial fishing boat
Fishing was probably the first use of the oceans by humans. In the last century, significant increases in commercial fishing have resulted in the over-exploitation of many fish stocks.
In New Zealand, fisheries are managed by a quota system that sets catch limits for commercially important species and aims at sustainable management of our fish stocks. The Royal Forest and Bird Protection Society (NZ) publishes the Best Fish Guide to try and encourage us to make more sustainable choices when purchasing seafood. The list evaluates fish stocks and bycatch levels and the fishing methods used.
Pollution
Our oceans have long been used as an intentional dumping ground for all sorts of waste including sewage, industrial run-off and chemicals. In more recent times, policy changes in many countries have reflected the view that the ocean does not have an infinite capacity to absorb our waste. However, marine pollution remains a major problem and threatens life in the sea at all levels.

Phytoplankton bloom
This image shows a large phytoplankton bloom that occurred around New Zealand in October 2009. The image was acquired by the Moderate-resolution Imaging Spectroradiometer (MODIS), flying aboard NASA’s Terra satellite.
Some marine pollution may be accidental, for example, oil spills caused by tanker accidents. Some may be indirect, when pollutants from our communities flow out to sea via stormwater drains and rivers. Some effects may not be immediately obvious, for example, bioaccumulation – the process where levels of toxic chemicals in organisms increase as they eat each other at each successive trophic level in the food web.

Explain the general distribution of life in aquatic systems as a function of chemistry, geography, light, depth, salinity, and temperature.
Answers
Different types of organisms can exist in a variety of aquatic environments due to the fact that they can vary significantly from place to place and that organisms within each water system will have evolved to adapt to their specific environment.
How does light affect aquatic life?Sunlight plays a vital role in the ocean’s ecosystem. First, sunlight enters the water column, warms it, creates currents, and is then absorbed by phosphorous-rich phytoplanktons. Phytoplanktons use the energy captured by phototrophs (pigments like chlorophylls) to convert water and nutrients into organic matter.
Light availability determines the types of organisms that can live in a particular part of an aquatic environment. The deeper the water depth, the less light it can penetrate until there is no light at all.
The salinity of water affects its density which in turn affects the movement of ocean currents. It may also affect marine life which needs to regulate the intake of salt water. There is a relationship between salinity, temperature, and water density. Therefore, any change in temperature or water density will affect the salinity of the water in the area.
Water chemistry parameters (pH, dissolved organic carbon, and hardness) play a role in metal toxicity by influencing the bioavailability of aquatic species of metals in water.

Which is an advantage of a natural gas burning power plant over an oil burning power plant
Answers
Answer:
Natural gas is a fossil fuel that burns relatively cleanly.
When natural gas is burned for energy, it produces fewer air pollutants and carbon dioxide (CO2) than when coal or petroleum products are burned to produce the same amount of energy.
An advantage of a natural gas-burning power plant over an oil-burning power plant is that the burning of natural gas produces no or less amount of air pollution as compared to that of oil or coal burning.
What is Natural gas?Natural gas may be defined as a type of non-renewable energy resource that typically synthesizes deep under the earth's surface. This gas is a mixture of hydrocarbons that primarily consists of methane.
The burning of natural gas generally releases very less or no amount of air pollutants like carbon dioxide, and other greenhouse gases which are harmful to all living entities. Natural gas is typically cleaner, environment friendly, and burned for energy.
But when coal, oil, or other petroleum products are burned, they release huge amounts of pollutants into the environment and make it toxic for all.
Therefore, it is well described above.

The two main types of minerals are macro minerals and trace minerals.
Explanation:
Macro means large in Greek. And your body needs larger amounts of macro minerals. Calcium, phosphorus, magnesium, sodium, potassium, chloride, and sulfur make up the macro mineral group.
A trace of anything indicates that only a small amount of it exists. Even while your body requires trace minerals, it only requires a small amount of each. Iron, manganese, copper, iodine, zinc, cobalt, fluoride, and selenium are examples of trace minerals.

D. Autotroph, producer
Answers
Answer: Autotroph, producer
Explanation: The grass gets eaten by primary consumer starting the food chain
In a food chain, the grass is referred to as an autotroph and producer. Therefore, option D is correct.
What are autotrophs?An organism is referred to as an autotroph or primary producer when it uses carbon from simple substances like carbon dioxide to create complex organic compounds. These creatures often obtain their energy from inorganic chemical reactions or light.
Both plants like blue-green algae and microorganisms like cyanobacteria are assumed to be autotrophs. Most plants are autotrophs because they create their own food through photosynthesis. But there are always exceptions to the norm. Some plants are parasitic and non-photosynthetic, getting their nutrition from a host.
Thus, the grass in a food chain is described as autotroph and producer. Therefore, option D is correct.

A.
Three–fourths of the F1 and one–half of the F2 plants will be tall.
B.
All of the F1 and three–fourths of the F2 plants will be tall.
C.
Three–fourths of the F1 and all of the F2 plants will be tall.
Answers
Answer:
Explanation:
Let T = tall allele (dominant), t = short allele
True breeds are homo-zygous.
So the gardener is crossing TT with tt, with the resulting genotype of F1 all equal to Tt, i.e. all Tall hetero-zygous.
When the F1 pea plants are allowed to self-polinate, F2 results in Tt crossing with Tt, with the genotypes TT, Tt, tT and tt, and phenotypes 75% tall and 25% short, tall being dominant.
