Provide a scientific explanation describing whether plants use the by-product of cellular respiration for photosynthesis, and determine the complementary relationship between photosynthesis and cellular respiration in terms of both matter and energy conversions. Claim:
Evidence:
Reasoning:
Rebuttal:
Answer:
Explanation:The process of photosynthesis converts light energy into stored chemical energy by converting carbon dioxide plus water into sugars plus released oxygen. ... Cellular respiration releases the energy needed to maintain body temperature despite ongoing energy transfer to the surrounding environment. Photosynthesis is the conversion of light energy into chemical energy by living organisms. The raw materials are carbon dioxide and water; the energy source is sunlight; and the end-products are oxygen and (energy rich) carbohydrates, for example sucrose and starch.

Why is it hard to observe winter insects
Answer:
As the Earth warms overall, insects are shifting toward the poles to colonize areas that are warmer than before in the summer months. Yet many of these insects lack the ability to survive the colder winters found in these regions. ... As the days stay warmer later into the fall, insects' bodies get confused.
Explanation:
1. How did scientists discover that all living things are made of cells?
2. How did Pasteur’s experiment with the flasks help disprove the idea that living things could just appear or come from nonliving things like water and air?
3. Why are nutrients needed for living things? Describe the difference between living and nonliving things.
Answer:
1-Modern replica of van Leeuwenhoek's microscope. As microscopes improved, scientists made more discoveries. In 1839, two German scientists, Matthais Schleiden and Theodore Schwann, viewed plant and animal tissues under a microscope. They concluded that all plants and animals were made up of cells
2-Pasteur's experiment with the flasks helps disprove the idea that living things could just appear or come from nonliving things like water and air because the flask without a lid grew microorganisms that cam from a living thing not air or water
3-Nutrients are chemical substances found in every living thing on Earth. They are necessary to the lives of people, plants, animals, and all other organisms. Nutrients help break down food to give organisms energy. ... Autotrophs are organisms that can make their own food.
Explanation:
Answer:
1: They used microscopes and by then they used it so much they microscoped an animal, a human, plants etc.
2: The flasks helped disaprove by microscoping everything.
3: Living things need nutrients and no living things dont.
Explanation:
write a summary about the cell theory
Answer:
Over the next two centuries after the discoveries of Hooke and Leeuwenhoek, biologists found cells everywhere. Biologists in the early part of the 19th century suggested that all living things were made of cells, but the role of cells as the primary building block of life was not discovered until 1839 when two German scientists, Theodor Schwann, a zoologist, and Matthias Jakob Schleiden, a botanist, suggested that cells were the basic unit of structure and function of all living things. Later, in 1858, the German doctor Rudolf Virchow observed that cells divide to produce more cells. He proposed that all cells arise only from other cells. The collective observations of all three scientists form the Cell Theory, which states that:
all organisms are made up of one or more cells,
all the life functions of an organism occur within cells,
all cells come from preexisting cells.
Though no one point of the Cell Theory is more important than another, the theory clearly states that the functions necessary for life occur in the cell. Findings since the time of the original Cell Theory have enabled scientists to "modernize" the theory, including points related to biochemistry and molecular biology. The modern version of the Cell Theory includes:
all known living things are made up of one or more cells,
all living cells arise from pre-existing cells by division,
the cell is the fundamental unit of structure and function in all living organisms,
the activity of an organism depends on the total activity of independent cells,
energy flow (metabolism and biochemistry) occurs within cells,
cells contain hereditary information (DNA) which is passed from cell to cell during cell division,
all cells are basically the same in chemical composition in organisms of similar species.
The Cell Theory is one of the main principles of biology. The points of the theory have been found to be true for all life. As with any scientific theory, the Cell Theory is based on observations that over many years upheld the basic conclusions of Schwann’s 1839 paper. However, one of Schwann’s original conclusions stated that cells formed in a similar way to crystals. This observation, which refers to spontaneous generation of life, was discounted when Virchow proposed that all cells arise only from other cells. The Cell Theory has withstood intense examination of cells by modern powerful microscopes and other instruments. Scientists continue to use new techniques and equipment to look into cells to discover additional explanations for how they work.

According to the unified cell theory, all living things are made up of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells. Later, Rudolf Virchow made significant contributions to this theory.
Why is it important to study cell theory?Cell theory is critical for understanding biology because cells are the foundation of all life. We can have unicellular organisms such as bacteria and yeasts. cell division, the division of a cell from one to two to four, is the foundation of all living things' growth and development.According to the unified cell theory, all living things are made up of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells.

I guess evolution could eventually occur causing the insect species to darken but since it's a drought it's probably a short period

An increase in the concentration of greenhouse gases, like carbon dioxide, in the atmosphere can increase the temperature on Earth. How would such an increase in temperature most likely affect Earth's water cycle?
Answer:
Global warming intensifies water cycle
Explanation:
Global warming can dramatically intensify the water cycle because this phenomenon is associated with an increase in temperature, thereby a higher amount of water is evaporated into the air and a higher amount of ice is melted at the poles. Warmer atmospheric air will have a higher amount of water vapor, increasing the frequency and intensity of rainstorms. In consequence, global warming can significantly increase the probability of flooding in coastal communities.

NEED HELP ASAP!!! Which two conditions are caused by blockage of a blood vessel?
A. hypertension and obesity
B. hypertension and high cholesterol
C. arrhythmia and stroke
D. heart attack and stroke
Answer:
D. heart attack and stroke
Explanation:
The two conditions that are caused by blockage of a blood vessel are heart attack and stroke. Hence the correct option is D.
Both heart attacks and strokes are medical emergencies that occur when a blood vessel is blocked, leading to a lack of blood flow to vital organs. In the case of a heart attack, a coronary artery supplying blood to the heart becomes partially or completely blocked, usually by a blood clot formed on a plaque in the artery's walls.
The blockage reduces or cuts off blood supply to a part of the heart, causing damage to the heart muscle. Similarly, in a stroke, a blood vessel in the brain is either blocked (ischemic stroke) or ruptures (hemorrhagic stroke), leading to decreased blood flow or bleeding in the brain. As a result, brain cells are deprived of oxygen and nutrients, causing damage or cell death.
Hence the correct option is D.
