Answer: Option B

The enzyme has changed shape because of high temperature.

Explanation:

Enzymes are biological catalysts in living organisms that speed up the rate of chemical reactions.

High temperature changes the shape of enzymes.

Increase or high temperature lead to decrease in enzymes activities. This is due to enzyme protein been denatures by high temperature which is the breaking of molecular bonds within the enzyme protein. When the enzymes bonds are broken, the shape of the enzymes changes and they no longer act as catalysts.

The presence of both inherent diversity and acquired diversity is called intersectionality. Inherent diversity refers to the characteristics we are born with, such as race, gender, and sexual orientation. Acquired diversity, on the other hand, includes the characteristics we gain throughout our lives, such as education, language proficiency, and work experience.

The presence of both inherent diversity and acquired diversity is called "cognitive diversity." Inherent diversity refers to the differences in traits that people are born with, such as race, gender, and ethnicity. Acquired diversity involves the differences in experiences and perspectives gained throughout a person's life, such as education, skills, and work experiences. Cognitive diversity is important in organizations because it fosters a wide range of ideas and opinions, leading to better problem-solving, innovation, and adaptability. Embracing cognitive diversity can create a more inclusive and effective work environment.

True. Air pollutants can come from both natural and man-made sources. Natural sources of air pollutants include dust storms, volcanic eruptions, and wildfires.

These events release particles and gases into the atmosphere, which can negatively impact air quality. On the other hand, man-made sources of air pollutants include industrial emissions, vehicle exhaust, and burning fossil fuels for energy production. These human activities release pollutants such as sulfur dioxide, nitrogen oxides, and particulate matter, contributing to air pollution.
2. True. Light pollution does negatively affect fireflies. Fireflies rely on their bioluminescent light signals to communicate and attract mates. However, artificial light sources can interfere with these signals, making it difficult for fireflies to find mates and reproduce. Additionally, light pollution can disrupt fireflies' natural behavior and breeding patterns, leading to a decline in their populations.
3. True. Excessive use of car horns and sirens is considered noise pollution. Noise pollution refers to the presence of excessive, unwanted, or disturbing sounds in the environment. Car horns and sirens emit loud and sudden noises, which can be disruptive and annoying. Noise pollution can have negative impacts on human health, causing stress, sleep disturbances, and impaired concentration.
4. False. Light pollution does not allow us to see the stars easier. In fact, excessive artificial lighting in urban areas can create a glare that obscures the view of stars and celestial objects. The bright lights in cities scatter and reflect off particles in the atmosphere, creating a phenomenon known as skyglow. This light pollution hinders our ability to observe stars, planets, and other astronomical features clearly. To see stars easier, it is necessary to reduce light pollution and seek areas with minimal artificial lighting.
5. False. Forest fires are not considered natural air pollution. While forest fires do release smoke and particles into the air, they are not categorized as air pollution. Forest fires occur naturally in ecosystems and play a role in maintaining ecological balance. However, when humans cause uncontrolled or excessive fires, it can lead to environmental damage and impact air quality. Forest fires caused by human activities can release harmful pollutants and contribute to air pollution.
In conclusion, air pollutants can come from both natural and man-made sources, light pollution negatively affects fireflies, excessive use of car horns and sirens is noise pollution, light pollution hinders our ability to see stars, and forest fires are not considered natural air pollution. By understanding these concepts, we can work towards reducing pollution and preserving our environment.

The ocean absorbs most of the excess heat from greenhouse gas emissions, leading to rising ocean temperatures.

Increasing ocean temperatures affect marine species and ecosystems. Rising temperatures cause coral bleaching and the loss of breeding grounds for marine fishes and mammals.

Rising ocean temperatures also affect the benefits humans derive from the ocean – threatening food security, increasing the prevalence of diseases and causing more extreme weather events and the loss of coastal protection.

Achieving the mitigation targets set by the Paris Agreement on climate change and limiting the global average temperature increase to well below 2°C above pre-industrial levels is crucial to prevent the massive, irreversible impacts of ocean warming on marine ecosystems and their services.

Establishing marine protected areas and putting in place adaptive measures, such as precautionary catch limits to prevent overfishing, can protect ocean ecosystems and shield humans from the effects of ocean warming.

Ocean warming is the rise in the temperature of the oceans. Global warming affects the ocean and increases its temperature as oceans absorb a lot of heat.

Global warming is the rise in the temperature worldwide due to the increased greenhouse gases that are released by the various pollutions from human activities.

Global warming has caused ocean warming as the oceans absorb the maximum heat from the atmosphere. The increased ocean heat absorption affects aquatic life and affects the environment and ecosystem balance.

The increase in ocean warming affects the temperature and the climatic conditions as it alters the precipitation rate, and melts the glaciers that leading to natural disasters.

Therefore, global warming affects the oceans and in return the climate.

The inheritance in humans is more complex as compared to the inheritance in plants as described by Mendel.

Mendelian inheritance patterns mostly refer to the inheritance of traits controlled by a single gene with two alleles. In plants, most characteristics are governed by a single gene but in humans, most of the traits are polygenic which means that they are governed by more than one gene.

Also, most of the genes in humans have more than two alleles and hence they do not follow simple Mendelian inheritance patterns.

In humans, the males have only one X chromosome (that contains sex-linked traits) and females have two X chromosomes, this also leads to more complex patterns of dosage compensation and inheritance in humans and they do not follow the basic Mendelian laws as the plants do.
