Two tectonic plates of different densities collide. Which of the following could form at the plate boundary? (Multiple answers)

1. island

2.mid-ocean ridge

3.rift valley

4.trench

5.volcano

Answers

The answer is Trench and Volcano, because when two plates of different densities collide. When an oceanic plate and a continental plate collide.

Trench and volcano could form at the plate boundary.

When two tectonic plates of different densities collide due to convection currents that are produced by the heat within the asthenosphere, a plate boundary (convergent) is formed. Deep trenches are usually formed where one of the plates slides beneath each other (a process called subduction). Trenches are elongated and often narrow cavity. The plate which is below will move down into the mantle, and there will be release of fluids from the rock which will partially melt the mantle. The molten rock will rise and may erupt violently to produce volcanoes.

Other features that could also form at the plate boundaries apart from trench and volcanoes are submarine mountain ranges and fault lines.

Which of the following roles does an enzyme play when the body produces sucrose into glucose and fructose?
A: An enzyme decreases the bodies need for sucrose
B: An enzyme increases the amount of sucrose available
C: An enzyme increases the rate at which the sucrose breaks down
D: An enzyme decreases the amount of fructose and glucose product available

Answers

the answer is C. an enzyme increases the rate at which the sucrose breaks down. also i think your pic is cute



Final answer:

In the production of glucose and fructose from sucrose, an enzyme, specifically sucrase, increases the rate of sucrose breakdown by reducing the activation energy required for the reaction.

Explanation:

When the body produces sucrose into glucose and fructose, an enzyme plays a crucial role in the hydrolysis process. The correct answer to the question is C: An enzyme increases the rate at which the sucrose breaks down. In the small intestine, sucrose is hydrolyzed to form glucose and fructose in a reaction catalyzed by sucrase. This specific enzyme binds to the substrate, sucrose, and catalyzes its breakdown. Enzymes like sucrase work by reducing the activation energy needed for the reaction to proceed, significantly speeding up the reaction. Without sucrase, the hydrolysis of sucrose is significantly slower.

Cell graphic organizer

Hello there! Unfortunately, your post does not include a question, and therefore we are unable to help you:( You can add attachments to a post by clicking on the paperclip if necessary:)

Cell Graphic Organizer: Cells have three main parts – the cell membrane, which encloses the cell; the cytoplasm, a jelly-like substance where organelles are suspended; and the nucleus, which houses genetic material.

A cell is the fundamental unit of life, and its structure can be comprehensively understood through a graphic organizer. At its core, a cell consists of three essential components. Firstly, the cell membrane forms a protective boundary, enveloping the cell and regulating the passage of substances in and out. Secondly, the cytoplasm, a gel-like substance filling the cell's interior, serves as a medium for the organelles—tiny structures that perform specific functions—to carry out their activities.

Finally, the nucleus, often referred to as the cell's control center, houses genetic material in the form of DNA, dictating the cell's characteristics and functions. This graphic representation provides a visual framework for grasping the intricate yet organized architecture of a cell, emphasizing the interconnected roles these structures play in maintaining life processes.

Why aren’t organelles considered to be basic parts of a cell

Answers

Core organelles are found in virtually all eukaryotic cells. They carry out essential functions that are necessary for the survival of cells – harvesting energy, making new proteins, getting rid of waste and so on.

Final answer:

Organelles are complex, specialized structures within eukaryotic cells that perform specific tasks, similar to how organs function in an organism. They are not considered basic parts of a cell because cells can function with a basic structure of a membrane, cytoplasm, and DNA, without the presence of these specialized organelles.

Explanation:

The term 'organelle' refers to the various structures within cells that perform specialized tasks, similar to how organs have distinct functions within the human body. Hence, organelles, such as the nucleus, mitochondria, lysosomes, chloroplasts, endoplasmic reticulum, Golgi apparatus, and others, are fundamental components of eukaryotic cells, not basic parts.

Eukaryotic cells, which include all animal and plant cells, have membrane-bound organelles and a nucleus enclosed by a membrane, often referred to as a 'true nucleus'. Within this nucleus, the cell's DNA is stored.

However, not all organelles are found in all cell types. For example, lysosomes, known as the cell's 'garbage disposal', are more common in animal cells while in plant cells, a similar process occurs in vacuoles. Further, plant cells have unique organelles such as chloroplasts and a large central vacuole.

In the perspective of the cell theory, the basic parts of a cell would include the cell membrane or plasma membrane, cytoplasm, and genetic material in the form of DNA.

How might the oceans on early Earth have formed?

Answers

The oceans on early Earth formed as the planet cooled and volcanic activity released gases through outgassing. Water vapor in the atmosphere condensed and created rain, which filled basins to form primitive oceans. Additional water from space may have contributed to this process.

Approximately 4.6 billion years ago, when Earth formed, it was a molten world without an atmosphere or oceans. Over time, Earth's early, hot surface began to cool, allowing for a solid crust to form. As the climate continued to cool and the crust solidified, volcanic activity was prevalent, emitting various gases, a process known as outgassing. The outgassed water vapor, along with gases like carbon dioxide (CO2) and methane (CH4), started to build Earth's early atmosphere.

Eventually, as the atmosphere cooled further, the water vapor started to condense, and Earth experienced its first rainfall. This condensation and the subsequent precipitation were crucial steps in the formation of Earth's oceans. Additional water is theorized to have been delivered by comets and asteroids striking the planet.

Over millions of years, and as the surface temperature dropped, persistent rainfall filled basins and low areas, forming the primitive oceans. The atmosphere, once hostile and rich in reducing gases like methane and ammonia, began to transform as the Earth evolved towards supporting life as we know it today.

By about 3.8 billion years ago, enough cooling had occurred to allow rainwater to stay liquid and not vaporize upon contact with the Earth's surface. Thus, the early warm, shallow oceans were formed in a reducing environment with little oxygen. Later tectonic activity would reshape these primitive oceans into the complex distribution of seas and continents present on modern Earth.

Which activity might lead to damage of a microscope and specimen

Answers

The correct answer is the application of the coarse adjustment to focus the specimen under high power.  

One should always remember while using the coarse adjustment to focus the microscope is to use it only with the low power objective. One should prevent the use of coarse adjustment when focusing on high power because the image moves in and out of focus too prompt that it becomes tough to accurately adjust the focus.  

Secondly, one may run the threat of crashing the objective into the slide, that is, why it is recommended to use the coarse focus only with the 4x low power objective. However, one can use the fine focus knob with all the objectives.


Final answer:

Improper cleaning of lenses, carelessly adjusting the focus and objective, misuse of immersion oil, and not securing the microscope when not in use can lead to microscope and specimen damage.

Explanation:

There are several activities that could potentially lead to damage of a microscope and specimen. These include activities such as not cleaning the lenses with lens paper, allowing the lens to come into contact with the slide by rapidly changing the focus, pushing an objective into a slide, and using the coarse focusing knob when using the 40× or greater objective lenses. Moreover, only using immersion oil with a specialized oil objective, generally the 100× objective and cleaning oil from immersion lenses after using the microscope is critical.

Damage may also come from negligence when a microscope is not being used, such as not covering it or placing it in a cabinet. Looking at a specimen, if the slide with the specimen is not properly secured and centered over the light, damage may occur. It is crucial to take the utmost care when using a microscope and handling specimens to avoid any damage that may affect the accuracy of your observations and study.

Now let's look at an example in a plant cell from a leaf. Use the slider to examine a plant cell before and after the plant was watered with very salty water. After watering with salt water, the plant wilted. Propose an explanation as to why the plant wilted using evidence from the cell diagrams

Answers

Answer:The reason for the plant that its leaf got wilted after being watered with salty water is that salty water is so dense that it does not allows for osmosis through the plant tissues ans eventually it dehydrates the plant by actually taking water out of the plant.

There are chances that the salt water can be poisonous to the plant. Too much salt interferes in the chemical processes which the plant uses to spread the nutrients in the plant. This can kill the plant.

The plant wilted is due to the fact that the plant was dehydrated.

The experiment that was carried out was about a plant that was watered with salt water and after watering the plant with salt water, it wilted.

It should be noted that salty water is dense and doesn't give room for osmosis to take place. This leads to dehydration as it takes water out of the plant.

Also, it should be noted that when the salt is too much, it causes harm to the plant as it interferes in its chemical process. This eventually leads to the plant wilting.

The topsoil is the upper and outermost layer of the soil. It exhibit high amount of organic matter and the microorganisms remain active in the layer. It is composed of mineral particles, water, organic matter and air. It is fertile in nature and can support plant growth.

The erosion of land by wind: The soil erosion can occur due to agents like wind and water. These agents displace the top layer of soil and the components are deposited to other places.

Plowing land without replanting: Plowing is an agricultural practice in which the compact and tight soil is improved by turning up using a tool. It is done before sowing of seeds. Plowing can result in the soil erosion by wind as the loose soil can be easily blown up by wind.

Overusing land: The land can be overused in agricultural practice and mining. These practices can remove the topsoil layer.

The structure that regulates what enters and leaves the cell is called

Answers

Final answer:

The plasma membrane is the cell structure that regulates what enters and leaves the cell. It has selective permeability, allowing only certain substances to pass through, providing both protection and support to the cell.

Explanation:

The structure that regulates what enters and leaves the cell is called the plasma membrane. This membrane separates the cell from the external environment and controls the passage of organic molecules, ions, water, oxygen, and waste in and out of the cell. The plasma membrane has the ability to regulate the concentration of substances inside the cell, a property referred to as selective permeability.

It allows only certain substances to pass through, while keeping others in or out, including ions such as Ca+, Na+, K+, and Cl¯; nutrients including sugars, fatty acids, and amino acids; and waste products, particularly carbon dioxide (CO2), which must leave the cell. Not only does the plasma membrane control what material enters and leaves the cell, but it also provides protection and support to the cell.
