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.

Answer: A. Lysosome
Explanation:
Phagocytosis is a process of endocytosis. Basically bringing stuff into the cell. Lysosomes are the organelles that break stuff down in a cell.
The material is entrapped/engulfed by the cell with its plasma membrane and inwardly cleaves to create a vacuole in the cell. Lysosomes seek out and break down this material so that its constituents can be utilized.

To study the details of protein molecules on the surface of a cell, a biologist would most likely use a
scanning electron microscope
transmission electron microscope
compound light microscope
dissecting microscope
The correct answer to this question is a Scanning Electron Microscope.
A scanning electron microscope (SEM) is a potent magnification device that collects data using concentrated electron beams.A concentrated electron beam is scanned across a surface by a scanning electron microscope (SEM) to produce a picture. The interaction between the beam's electrons and the sample results in a variety of signals that can be used to learn more about the surface composition and topography.A scanning electron microscope has several uses, provides detailed three-dimensional and topographical imaging, and may gather a variety of information from various detectors.
Therefore, the correction option is that a Scanning Electron Microscope should be used to study the surface protein details of a cell.

A mosquito bites your arm. You feel the sting, jump, and slap the mosquito. Which of your body’s organ systems are involved?
If a mosquito bites your arm. You feel the sting, jump, and slap the mosquito the body’s organ systems that are involved are nervous system and muscular system.
What is the nervous sistem?The nervous system is the one that will transmit the signals through the body thanks to the brain and they will also be transmitted in the opposite way. Thanks to this we can have control of our abilities to move, think, breathe, among others. Also through the collection of sensory, heat and painful stimuli we can prevent damage to the body by responding by removing the part of the body that receives the damage through a reflex, such as hitting the mosquito when feeling the itch.
Therefore, we can confirm that if a mosquito bites your arm. You feel the sting, jump, and slap the mosquito the body’s organ systems that are involved are nervous system and muscular system.

Adenosine triphosphate (ATP) is a cell's energy currency. All of the following statements about ATP are true, except ATP is used to lower activation energy in enzymatic reactions.
A) ATP is used to lower the activation energy in enzymatic reactions.How does ATP affect enzyme activity?Enzymes allow chemical reactions to proceed with activation energy provided by the catabolism of ATP. When cells convert glucose and oxygen into carbon dioxide and water, they use 2 molecules of ATP as activation energy and gain 36 to 38 molecules of ATP in return. Without enzymes, this would not be possible.

Develop a plan to test the hardness of a sample of feldspar using the following items : glass plate , copper penny and a streak plate
Feldspar has a hardness of 6 and they improve the toughness durability and strength of the ceramic body.
The feldspar is considered the group of rocks which forms the aluminum tectosilicate minerals and they also contain other types of cations such as sodium, barium, potassium, and calcium.
The minerals that scratch the glass they have to be harder than 5.5 inches and feldspar can be used on a glass plate to do this feldspar is needed to run over anything which is harder than 6 inches otherwise detecting hardness is hard.
A copper penny has a hardness of about three hence the hardness test by a copper penny is not possible by a feldspar.
A streak plate has a hardness of over 6.5 to 7 and that is why it can be used to detect the hardness as feldspar has a hardness of 6 it can be run over the streak plate and a test can be done.
The benefits of feldspar are it has good dispersibility, has high chemical inertness so is not much reactive, ph is stable, resistant to abrasion highly, it has low viscosity at high filler loading and it cannot get frozen and also has a good refractive index.
it is fine-milled graded and used in many different products.

ivan is investigating the path of home runs in baseball
The correct answer is the last option which states the distance that each home run travels.
This is because, the main aim of Ivan is to investigate the path of home runs in baseball. And, the best way to do so would be to calculate the distance that each home run travels. By studying the time of the day when each home run is hit, he won't be able to examine the path. It would rather be more useful to see at what time the frequency of home runs is the maximum. The scores of the game would also not reveal the path travelled by the home runs as they are not calculated on the basis of the distance travelled. Similarly, the names of the players hitting the home runs might not provide the necessary information for this experiment.Thus, the correct answer is the distance that each home run travels.
