Van Helmont concluded that most of the mass the plant gained had come from water, because that was the only thing that he had added to the pot. Van Helmont's experiment accounts for the "hydrate," or water, portion of the carbohydrate produced by photosynthesis.
How might retaining too much heat be a disadvantage to an organism?
Excessively heat can damage the plasma membrane and disrupt subcellular structures such as membrane proteins and enzymes.
What are subcellular structures?The following are the primary subcellular structures found in animal cells: The nucleus is where genetic material is stored.
Cell membranes regulate what enters and exits the cell. Mitochondria: aerobic respiration site. Ribosomes are the sites where proteins are synthesized.
Protein denaturation occurs at high temperatures and affects protein folding, bonding, and other types of behavior.
Furthermore, membrane proteins play an important role in cell function regulation. If these are disrupted, the system will be unable to maintain homeostasis, or a stable internal environment.
Heat can damage the plasma membrane and disrupt subcellular structures like membrane proteins and enzymes.
Thus, this way, retaining too much heat can be a disadvantage to an organism.

b. 46, 23, 23
c. 46, 12, 12
d. 46, 46, 46
Answer: B is the answer
Following mitosis, the daughter cells would each have a total of 46
chromosomes.
After meiosis I, the two daughter cells would have 23 chromosomes, and
after meiosis II it will still remain as 23 chromosomes.
Mitosis is a type of cell division that involves the production of identical
daughter cells. The daughter cells usually contain 46 chromosomes with all
the parent traits present.
Meiosis is a type of cell division which produces sex cells and for
reproduction. It involves generating unique daughter cells which is gotten by halving the 46 chromosomes to become 23 chromosomes.

An increase in body fluids leads to an increase in kidney filtration which leads to an increase in kidney output (urine). What type of feedback is this?
Answer:
Positive feedback.
Explanation:
An increase in body fluids causes increase in kidney filtration which leads to higher production of urine, this type of feedback is known as positive feedback because when there is increase in the output, this is called positive feedback while on the other hand when there is decrease in the output we called it negative feedback. So we can see that the output of the kidney is higher concentration of urine so we can say that it is a positive feedback.

Meiosis- produce gametes, two cell division, 4 genetically different haploid cells
Hope this helps :)
The group that is correct regarding mitosis and meiosis is group 2 as they said that mitosis is involved in the growth and repair of cells and undergoes cell division once, while meiosis is involved in reproduction through fusion of gametes and undergoes cell division twice. The correct option is B.
What is cell division?Type of cell division by which a parent cell divides into two or more daughter cells when a parent cell divides into two or more daughter cells. Cell division is typically part of a larger cell cycle.
Cell division occurs in two stages namely mitosis and meiosis. When most people say cell division, they're referring to mitosis, the method by which new body cells are formed.
Meiosis is the process by which egg and sperm cells are formed. Mitosis is a necessary process for life.
The group 2 is stating the same that mitosis is the division for growth and repair and is done in only once, and meiosis is the process of gamete formation and occurs twice.
Thus, the correct option is B.

Greenhouse gases are measured by their ability to trap outgoing solar radiation and convert it to heat, warming the atmosphere.
Global warming potential is defined as the ability of an atmospheric gas to contribute to increasing global temperatures and
anthropogenic climate change. Carbon dioxide is used as a baseline for global warming potential, with a GWP of 1. What best
explains why CFCs (chlorofluorocarbons) have a GWP
nearly 5000?
Answer:
Greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals, trap some of the Earth's outgoing energy, thus retaining heat in the atmosphere. This heat trapping causes changes in the radiative balance of the Earth—the balance between energy received from the sun and emitted from Earth—that alter climate and weather patterns at global and regional scales.
Multiple lines of evidence confirm that human activities are the primary cause of the global warming of the past 50 years.1 Natural factors, such as variations in the sun's output, volcanic activity, the Earth's orbit, the carbon cycle, and others, also affect Earth's radiative balance. However, beginning in the late 1700s, the net global effect of human activities has been a continual increase in greenhouse gas concentrations.
This change in concentrations causes warming and is affecting various aspects of climate, including surface air and ocean temperatures, precipitation, and sea levels. Human health, agriculture, water resources, forests, wildlife, and coastal areas are all vulnerable to climate change.
Many greenhouse gases are extremely long-lived in the atmosphere, with some remaining airborne for tens to hundreds of years after being released. These long-lived greenhouse gases become globally mixed in the atmosphere and their concentrations reflect past and recent contributions from emissions sources worldwide. Others, like tropospheric ozone, have a relatively short lifetime in the atmosphere.

Why are plants important to the carbon water and nitrogen cycles?
Answer:
The carbon and water cycle I know, but I can't help with the nitrogen cycle. Sorry.
Explanation:
Carbon cycle - The role that plants play in the carbon cycle is that they take in our carbon dioxide and put out oxygen, which we breathe. So we give the plant air and they give us air.
Water cycle - The role that plants play in the water cycle is when it rains, the plants absorb some of the water in their roots, thus making them strong and therefore helping the ground not become a mud hole.
Sorry that I can't help with the nitrogen cycle. But I hope what I was able to help you with helps!

Answer:
metal shields
Explanation:
I took the quiz and exam
Humans are shielded from radiation by metal parts of a microwave oven. So, the correct option is C.
What is Microwave oven?A microwave oven, often known as a microwave or electronic oven, is a device that uses microwaves, which are high-frequency electromagnetic waves, to cook food. A microwave oven is indeed a compact, box-shaped oven that increases food's temperature by exposing it to an electromagnetic field with a high frequency.
Water, lipids, carbohydrates, and a few other molecules absorb the microwaves, which causes their vibrations to produce heat. Hence, cooking time is significantly shortened because the heating takes place inside the food rather than warming the air around it. Metal components of a microwave oven protect people from radiation.
Therefore, the correct option is C.
