why plants need the carbohydrates they produce in photosynthesis?

Answers

Answer: Carbohydrate make up part of the cellulose, giving plants strength and structure.

Explanation:

Answer:

Green plants create carbohydrates on their own through the process of photosynthesis. Those carbohydrates are the plant's source of fuel for growth. If even one basic ingredient a plant needs for photosynthesis is absent or lacking, the plant's health can suffer, resulting in stunted growth or reduced production.

Which are included in the inflammatory response? Select three options.

pain
swelling
antibodies
mucus
rednes

Answers

Answer:

the answer is redness, pain and swelling

Explanation:

The primary indicators of inflammation include discomfort, heat, redness, edema, and functional loss.

What are the main symptoms of inflammatory response?

Redness (Latin rubor), heat (Latin calor), swelling (Latin tumor), and pain are the four primary indicators of inflammation (dolor). Small blood vessels in the injured area enlarge, resulting in redness.

Inflammatory cells and cytokines are the initial responders that your immune system dispatches (substances that stimulate more inflammatory cells).

Due to an allergic reaction, several of these symptoms are visible here. Heat, discomfort, redness, swelling, and loss of function are the five primary symptoms (Latin calor, dolor, rubor, tumor, and functio laesa).

Therefore, redness, pain, and swelling are included in the inflammatory response.

Plz help!! We cannot survive without plants, while they would be fine without us. Explain.

Answers

Answer:

We cannot survive without plants because they give us oxygen and food. Plants would be fine without us because the earth gives them everything they need. The sun provides energy; rain, bodies of water, and groundwater provide water; the atmosphere provides nitrogen and carbon dioxide--all of these factors are required for photosynthesis to occur. This is how plants make glucose to feed themselves. Additionally, plants reproduce by several means, whether by pollination or wind spreading seeds to the ground.

Explanation:

Humans cannot survive without plants, while they would be fine without humans because plants produce oxygen.

Photosynthesis:

It is the process in the plant that produces glucose using the Carbon dioxide and water in the presence of sunlight.

During the process plants release Oxygen as byproduct which is used by all animals in the earth.Photosynthetic plants are the only source of Oxygen in the Earth.Plants are the primary producers in the food chain. Hence, consumers will not able to get the food.

Humans do not do anything that is compulsive need of plants.

Therefore, humans cannot survive without plants, while they would be fine without humans.

Analyze the oxygen levels of the victims. Were the levels higher or lower than normal? How can you reconcile this observation with the cause of death being hypoxia

Answers

Answer:

In the case study of the Chicago cyanide murder, the oxygen levels were very low which lead to the death of the cells in the body (there would be signs of dead cells in the victims' bodies).

Explanation:

The mitochondrion is the powerhouse of all cells in the animal body, it is responsible for cellular respiration and production of adenosine triphosphate or ATP.

When the cyanide stops the activities of the mitochondrion, each cell in the body begins to die as a result of hypoxia, which is a condition where the body or a part of the body is deprived of oxygen.

Explain the relationship between photosynthesis and cellular respiration using the following words: Photosynthesis, Cellular respiration, Atmosphere, Chloroplasts, Sunlight, Reactants, Products, Carbon Dioxide (CO2), Glucose (C6H12O6), Water (H2O), Oxygen (O2), Energy (ATP)

Answers

Answer:

Photosynthesis converts carbon dioxide and water into oxygen and glucose.  Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

Earth's second atmosphere (atmosphere III) was a thick atmosphere of primarily water vapor and carbon dioxide,
What effects did this have on Earth?

A. Heat energy was retained and water vapor condensed
B. Ultraviolet light split water vapor into hydrogen and oxygen.
C. Increased oxygen allowed reptiles to thrive.
D. Helium and hydrogen gases escaped earth's gravity

Answers

The answer is A.
Heat energy was retained and water vapor condensed . Hope this helps (:

This had the same effect on Earth as it did on Mars. Heat energy was conserved, and water vapor was condensed.

What was the second atmosphere of Earth like?The second atmosphere, which remained on the planet, was formed by volcanic outgassing and comet ices. This atmosphere had almost no oxygen, but plenty of water vapor, carbon dioxide, nitrogen, and methane.When Earth's crust began to cool 2.5 billion years ago, there was less water vapor in the sky, and more water condensed into liquid, resulting in the formation of Earth's second atmosphere.The second atmosphere was formed by volcanic outgassing and comet ices, and it was the first to survive on Earth.A secondary atmosphere is a planet's atmosphere that did not form through accretion during the formation of the planet's star. Instead, a secondary atmosphere forms as a result of internal volcanic activity or the accumulation of material from comet impacts.
