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?

Answers

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.

How might retaining too much heat be a disadvantage to an organism?

Answers

One disadvantage of having a large surface area to volume ratio is the heat loss. An organism that has larger surface area has high rate heat gain and heat loss. Therefore they need to eat or acquire nutrients faster in order to sustain life.

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.

Homeostasis is maintained by which of the following organ systems in humans?
A. Multiple organ systems working together
B. The muscular system
C. The endocrine system
D. The nervous system

Answers

A. Multiple organ systems working together

Explanation:

All of the organ systems work together to maintain homeostasis in humans because each system does something different. For example, the circulatory system delivers oxygen rich blood to the bones and the bones create new blood cells. When one thing is wrong with one system, it affects all of the systems, like a disease. Another example of this would be the central nervous systems and endocrine working together to coordinate messages to the brain about the body's state while resting and exercising to maintain homeostasis.

Explanation:

Several groups of students were comparing the processes of mitosis and meiosis. Each group came up with a different answer for how the two processes are different.  

Mitosis- growth and repair one cell division 2 genetically identical diploid cells

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.

C) an oil
D) water

The answer is B an enzyme !

Answers

Answer:

[tex]\boxed {\boxed {\sf Enzymes}}[/tex]

Explanation:

Meat is a good source of protein because it is the main component. Hormones, oil, and water won't really produce a substance when added to meat.  Enzymes break down different substances. The right enzyme can break down proteins. The monomer, or building block, of protein is an amino acid. Therefore, when a protein is broken down, amino acids are produces.

So, from the information above, we can assume that the substance is an enzyme. Enzymes break down meat/protein into amino acids.

*Please Help* Invertebrates have a higher net production efficiency than mammals. Which statement most likely explains this observation?


A. Invertebrates are more abundant than mammals in an ecosystem.

B. Mammals maintain their body temperature; invertebrates don't.

C. Most mammals are secondary consumers. Most invertebrates are primary consumers.

D. Invertebrates have smaller bodies than mammals.

Answers

Answer:

C. Most mammals are secondary consumers. Most invertebrates are primary consumers.

Explanation:

Net production efficiency (NPE) refers to how efficient an organism at one trophic level utilizes and transfers energy to the next trophic level. Ceetain organisms called CONSUMERS obtain energy by feeding on other organisms. They use this energy for their metabolic activities and transfer the rest when eaten or fed on.

As the trophic level increases, the net production efficiency decreases. This is because organisms at the lower level use energy less than those at higher trophic levels. In this question, invertebrates are mostly PRIMARY CONSUMERS (lower trophic level) while mammals are mostly SECONDARY CONSUMERS (higher trophic level). Therefore, invertebrates use energy more efficiently (less) than mammals, making them have a HIGHER net production efficiency than mammals.

During cellular respiration what is the direct source of the energu used in the cells of consumers?

Answers

Answer:

Consumers use chemical energy from the chemical bonds within organic molecules such as carbohydrates, lipids,  and amino acids.

Explanation:

Heterotrophs are consumers; they ingest or absorb organic matter (lipids, carbohydrates, proteins, etc.)  made by autotrophs or producers for their energy consumption. Autotrophs include plants, bacteria, and other photosynthesizing organisms, while heterotrophs include animals, fungi, protists, and bacteria.

Heterotrophs obtain energy from food through the process of cellular respiration. For instance, during aerobic respiration in mitochondria, they break down sugars in the form of glucose into carbon dioxide and water to obtain energy in the form of ATP or adenosine triphosphate.

aerobic respiration:      C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP

                                      glucose+ oxygen →  carbon dioxide+ water+ energy
