Answer: It is photosynthesis!

The major source of atmospheric oxygen is photosynthesis carried out by plants, algae, and some bacteria where they use sunlight, water, and carbon dioxide to produce glucose and oxygen. This oxygen is released into the atmosphere, enriching it with this vital gas. The oxygen-rich atmosphere we have now is largely the result of billions of years of photosynthetic activity, particularly by ancient cyanobacteria.

The major source of atmospheric oxygen is photosynthesis carried out by plants, algae, and some bacteria. During photosynthesis, these organisms convert carbon dioxide and water into glucose and oxygen.

This process occurs in the chloroplasts of plant cells where chlorophyll captures sunlight and converts it into energy. The oxygen produced during photosynthesis is then released into the atmosphere, contributing to the oxygen content of our planet's atmosphere.

Therefore, photosynthesis is the main process responsible for the presence of oxygen in the Earth's atmosphere.

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.

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.

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.

Plants’ nonspecific immune responses includes cell-surface receptors (pattern recognition proteins) which allow them to identify certain patterns characteristic for pathogens.  Activated receptors trigger the production of chemical signals that may initiate both local and systemic defense responses. Sometimes when a plant is affected by infection, it triggers rapid localized programmed cell death to stop the infection further.  When it comes to defense form the herbivores, plants have physical barriers (plant cell walls and their extensions), some antibiotic compounds (phytoalexins), and even enzymes that can defend them.

It would be first one.

A chemical equation is balanced, when there are the same amount of atoms in both sides of the equation. Here are some examples of non-balanced and balanced equations:

[tex]O_{4} + CO_{2} \neq O_{3} +CO_{2}[/tex] → non-balanced

[tex]H_{8} + C_{2} = 2H_{4} + C_{2}[/tex] → balanced

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.

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.

Photosynthesis and respiration should balance each other out.

Cellular respiration and photosynthesis are both dependent on each other, thus creating a cycle. Respiration creates carbon from oxygen, while photosynthesis takes that carbon created and reuses it to make oxygen. If they are creating/using carbon at the exact same rate, everything should stay the same. I think that's the answer you were looking for, anyways. Hope I helped :)

Calcitonin is ahormone that is poduced in humans by the parafollicular cells (other wise known as c-cells) of the thyroid gland. Therefore, inhibition of the osteoclasts directly reuces the amount the amount of calcium released into the human blood. This is just a simple explanation so now all you have to do is understand what will happen when you combine calcitonin and parathyroid.

Parathyroid hormone is secreted from parathyroid glands. Parathyroid hormone increases calcium levels in the blood when they are too low. Whereas as calcitonin is a hormone secreted by the parafollicular cells of the thyroid gland. It works antagonistically to the parathyroid hormone. This means that calcitonin reduces calcium levels in the blood when it is high. It is, therefore, the secretion of both calcitonin and parathyroid hormone is determined by the level of calcium in the blood.

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.

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.
