Answer: They proved it causes cancer,

Explanation:

There was a change in the  view on smoking after 1960. change was influenced by declaring tobacco as an addiction and that it can cause cancer. It started in the 1964.

Answer:

Explanation:

The major cause of the change that society had on its view on smoking since 1960 was because of scientific information wherein scientists found that smoking causes cancer.

Ever since scientists discovered that smoking is bad for the lungs and the body in general, over time there became fewer and less people who do it. The smoke of cigarettes contains around 70 chemicals called carcinogens. These are known to cause cancer. So, society has changed its view on smoking since 1960.

Active transport and facilitated diffusion are two different mechanisms of moving substances across a cell membrane, with key differences in energy requirement, direction of movement, and specificity.

What is an active transport ?

Active transport is the movement of molecules or ions across a membrane against their concentration gradient, which requires energy in the form of ATP (adenosine triphosphate). Active transport can move substances from an area of low concentration to an area of high concentration, and it is often used by cells to maintain concentration gradients and perform functions like nutrient uptake and waste removal.

Facilitated diffusion, on the other hand, is the passive movement of molecules or ions across a membrane with the help of transport proteins. Facilitated diffusion moves molecules or ions from an area of high concentration to an area of low concentration, following the concentration gradient, and does not require energy input from the cell. Facilitated diffusion is often used to transport large or charged molecules that cannot diffuse across the membrane on their own.

Another key difference between active transport and facilitated diffusion is specificity. Active transport requires specific transport proteins, called pumps, that are designed to move specific molecules or ions. In contrast, facilitated diffusion can use a variety of transport proteins that are specific to certain molecules or ions, but can often transport a range of similar molecules.

In summary, the main differences between active transport and facilitated diffusion are that active transport requires energy input and can move substances against their concentration gradient, while facilitated diffusion is passive and moves substances along their concentration gradient. Additionally, active transport requires specific transport proteins and can be highly selective, while facilitated diffusion is less selective and can use a variety of transport proteins.

The image represents the continental-continental boundary. When two continental plates collide, that's another kind of convergent plate boundary. The continental lithosphere is very thick and has a low density. The continental lithosphere cannot subduct. So when two mainland plates impact, they simply crush together.

Plate tectonic boundaries come in three varieties: plate boundaries that are transformed, divergent, and convergent. The three primary types of plate boundaries are depicted in this image: transform, convergent and divergent.

Answer:

A Nucleotide is a compound consisting of a nucleoside linked to a phosphate group. Nucleotides form the basic structural unit of nucleic acids such as DNA.

The process that is part of the carbon cycle is Fixation. Fixation is the process by which atmospheric carbon dioxide (CO2) is converted by living organisms into organic compounds, such as carbohydrates, through photosynthesis or chemosynthesis.

The carbon cycle refers to the natural processes through which carbon is exchanged between living organisms, the atmosphere, oceans, and geosphere.

The process of fixation is an essential part of the carbon cycle, as it is responsible for converting inorganic carbon dioxide (CO2) into organic carbon compounds through photosynthesis.

In this process, plants and other autotrophic organisms absorb atmospheric CO2 and convert it into glucose and other organic molecules, which can then be used to build other complex organic molecules, such as proteins and carbohydrates.

These organic compounds are then passed along the food chain to heterotrophic organisms, which use them for energy and other metabolic processes. Carbon is ultimately released back into the atmosphere through cellular respiration, decomposition, and combustion, completing the carbon cycle.

Therefore, the correct answer to the question is D.

The best fishing practices solution to promote the sustainability of the orange roughy population is by setting up quotas for the number of orange roughies that can be caught.

It has been demonstrated how biological systems can be both persistent and productive. However, at this time, it stands for the need to develop the sustainable models necessary for both the survival of planet Earth and the human species. Humans must reassess their social responsibilities, environmental preservation, and economic tactics in order to attain the intended goals.

The predatory orange roughy is found in deep seamounts or undersea mountains in the majority of ocean basins worldwide. With individuals surviving for more than 150 years, this species, also known as the Atlantic roughy, is one of the longest-lived marine fish species. The orange roughy is susceptible to overfishing due to its lifespan and other life history traits.

Hence, the best fishing practices solution to promote the sustainability of the orange roughy population is by setting up quotas for the number of orange roughies that can be caught.

Answer:

LIGHT ENERGY is converted to CHEMICAL ENERGY in the process of PHOTOSYNTHESIS

Explanation:

According to the law of conservation of energy, energy cannot be created nor destroyed but can only be changed from one form to another. This means that no form of energy gets destroyed but only transformed. This is evidently so in so many natural processes including the process of PHOTOSYNTHESIS undergone by plants.

Photosynthesis, which is the way plants obtain their food via sunlight, converts the LIGHT ENERGY of the sun to CHEMICAL ENERGY in glucose produced. Hence, photosynthesis obeys the law of conservation of energy.

The usage of synthetic plant hormones for the modification of plant growth can have environmental implications.

Factors to consider

1. Ecotoxicity: Synthetic plant hormones, if not properly regulated or used in excessive amounts, can pose risks to non-target organisms and ecosystems. They may affect the growth and development of other plants, beneficial insects, and microorganisms, potentially disrupting ecological balance.

2. Soil and Water Contamination: Improper application or disposal of synthetic plant hormones can lead to soil and water contamination. Runoff from treated fields or improper disposal of unused hormones may introduce these compounds into water bodies, potentially affecting aquatic organisms and overall water quality.

3. Resistance and Persistence: Repeated and excessive use of synthetic plant hormones can contribute to the development of resistance in target plant species. This can lead to the evolution of herbicide-resistant weed populations, requiring higher doses or different chemicals to achieve the desired effect. Moreover, some synthetic hormones may persist in the environment for extended periods, potentially impacting subsequent crops or natural vegetation.

4. Non-target Effects: Synthetic plant hormones may influence the growth and development of unintended plant species, leading to unintended consequences such as changes in biodiversity, alteration of natural plant communities, or interference with the natural ecological succession.

5. Human Health Concerns: The potential impacts of synthetic plant hormones on human health are an area of ongoing research.

The second stage of protein synthesis is called translation which is the process of translating or deciphering the genetic code of the DNA copy.

RNA polymerase breaks down into DNA molecules which contain the segments which are genes. Within a gene, there are ends called the promoter and the terminator. RNA polymerase will move from the terminator to the promoter to break down the DNA. If RNA polymerase has succeeded in the promoter, the initiation process is complete.

When the mRNA that carries the DNA copy succeeds in bringing it to the ribosome, a translation process occurs, namely the process of translating or deciphering the genetic code of the DNA copy that has been carried by the previous mRNA. This genetic code will produce polypeptides as a building block for proteins.
