what are the steps of enzyme activity?
Answers
1. The enzyme and the substrate are in the same area. Some situations have more than one substrate molecule that the enzyme will change.
2. The enzyme grabs on to the substrate at a special area called the active site. The combination is called the enzyme/substrate complex. Enzymes are very, very specific and don't just grab on to any molecule. The active site is a specially shaped area of the enzyme that fits around the substrate. The active site is like the grasping claw of the robot on the assembly line. It can only pick up one or two parts.
3. A process called catalysis happens. Catalysis is when the substrate is changed. It could be broken down or combined with another molecule to make something new. It will break or build chemical bonds. When done, you will have the enzyme/products complex.
4. The enzyme releases the product. When the enzyme lets go, it returns to its original shape. It is then ready to work on another molecule of substrate.

How do temperature and salinity affect deepwater currents?
As temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions.
They create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
They equalize the forces on undersea currents caused by the Coriolis effect as they replace more dense water with less dense water.
They create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean.

Gravity on Earth is 9.8 m/s2, and gravity on the Moon is 1.6 m/s2.
So, if the mass of an object on Earth is 40 kilograms, its mass on the Moon is____ kilograms and its weight on the Moon is _____newtons.
Answers
Answer:
Mass = 40 kg Weight = 64 N
Explanation:
Mass does not change. 40 kg on Earth = 40 kg on the moon = 40 kg on Saturn, etc.
Weight = Force = Mass*Acceleration
So, Weight = 40 kg * 1.6 M/s^2 = 64 newtons

Plant cells have a cell wall, a large central vacuole, and plastids such as chloroplasts. The cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell, providing structural support and protection
Answer: Really Sayuri
Explanation:
Plastids, a sizable center vacuole, and a rigid cell wall are all features of plant cells. The cell wall offers skeletal defense and support. Water and nutrients can enter and exit cells thanks to pores in the cell membrane. When water penetrates the plant cell, the cell wall also stops the cell from bursting.
Cell Wall: this provides extra strength and support for the plant cell so it doesn't burst when gaining water by endosmosis.
Chloroplasts: this is where photosynthesis takes place.
Large permenant vacuole: this stores several pigments, ions, enzymes and organic and inorganic substances.

The global population has increased immensely over the last two centuries. Humans use fossil fuels to do a variety of tasks from heating their homes to travel to production of everyday products. As the human population has increased, so have the global fossil carbon emissions.
Write a scientific explanation that describes total world carbon emissions in 2050 if the world’s population decreases to five billion people.
Claim:
Evidence:
Reasoning:
Answers
Answer:
The earth would eventually become become a brown and grey wasteland and the blue sky and rainbows and things like that will be rare rain would be highly acidic
Evidence: There are less people which means less cars will be driven less oil will be used etc. also fossil fuels are non renewable resource which means fossil fuels will be harder to find overall diving up prices of gas,heating,etc which might make Deter people from using fossil fuels and switching to something cheaper. At this point to people will dislike fossil fuels more then now.
Reasoning: I think people won’t like fossil fuels for 2 good reasons. First the driven up price. Second there will be noticeable effects from fossil fuels it 2050. It can make crops harder to grow which could lead to famine and a Recession because driven up food prices and it will hurt the economy. Towns will slowly flood. Arctic species will die so on. So a poor family’s that can’t afford food won’t spend more money on something that overall hurts them. They will despise people who use fossil fuels and it will become socially wrong. Civilization at that time might also be working on them self. Population decreased a major amount. Something bad happened. And if what ever caused the decline in population was caused by humans which there’s no way to tell, they might try to improve human habits try not to begin wars, work on helping each other, and most importantly don’t harm there plant.

Answers
Answer:
Explanation:
The cell theory basically just tells you that all living things have more than one cell and that cells are made from other cells. It basically just tells you that cells are our foundation for life, without cells we can't live.
For, example, blood cells. If we didn't have blood cells our body's organs can't get the oxygen and nutrients they need to survive. Without blood cells we could get weak or we could just die instantly.
Hope this helps!!!
The basic tenets of cell theory are that all living things are made up of cells and that cells are the basic units of life. However, cell theory dives deeper than that. ... In other words, everything is made up of cells. Cells are the basic building blocks of organisms and of life.

Water, carbon and nitrogen cycles are biogeochemical cycles that exist in the biosphere to maintain a balance in the flow of energy and matter.
What patterns are observed in the cycles?There are three major biogeochemical cycles - water, nitrogen and carbon - that exist in nature which allow the transfer of matter and energy between the living and non-living things of the biosphere.
All the three cycles involve the exchange of gases from the plants to atmosphere to the animals or microbiota, which is again released back into the atmosphere.
Plants absorb the nitrogen, carbon and water in different forms from the environment which is then passed on.
Another similar pattern seen amongst the three is that humans release carbon, nitrogen and oxygen in various forms.

4. Name three agents of dispersal. In each case, give an example of a plant whose seeds are dispersed by the agents
Answers
Answer:
Three agents of dispersal are:
Wind: Some plants have adaptations that allow their seeds to be carried by the wind. Examples include dandelions, which have feathery bristles attached to their seeds that help them float through the air, and maple trees, which have winged seeds called samaras that spin as they fall, allowing them to travel long distances.Animals: Some plants have adaptations that allow their seeds to be dispersed by animals. For example, burrs have hooks or spines that attach to the fur of animals, allowing the seeds to be carried away from the parent plant. An example of a plant that uses this method is burdock. Some fruits, such as berries, are also eaten by animals, which then excrete the seeds in their droppings, allowing them to be dispersed over a wider area. An example of a plant that uses this method is the blackberry.Water: Some plants have adaptations that allow their seeds to be dispersed by water. Examples include coconuts, which have a fibrous husk that can float on water, allowing the seed inside to be carried away by ocean currents, and water lilies, which have seeds that float on the surface of the water and are dispersed by the movement of the water.PLEASE GIVE ME BRAINLIEST!
Also, one of them is wind since the seeds that have wings like dandelions fly with wind.
Finally it is animals - if any animal goes near seeds it can stick on the animals and it goes far from its original plant (where it came from originally.

Identical twins share all of their genes, while fraternal twins share only half of their genes. For twins with the disorder schizophrenia, about 50% of indetical twins share the disease, while only about 10-15% of fraternal twins do. What does this tell you about the way genetic and envionmental facotrs affect schizophrenia?
Answers
Answer: The environmental factors likely interact with genetic liability negatively to produce disorders in the schizophrenic spectrum. Genetic and environmental components of the disorder are examined, as well as their interactions in producing either neurodevelopmental syndromes or schizophrenia itself.
Explanation:
The differences between identical and fraternal twins are due to how they are conceived. When identical twins are conceived, the fertilized egg splits into two, causing two separate embryos to grow. When fraternal twins are conceived, two eggs are fertilized at the same time.
Many factors normally contribute to the onset of schizophrenia
The actual causes of schizophrenia are not fully understood.
Brain chemistry: Abnormal functioning of neurotransmitters such as dopamine can cause schizophrenia.
Heredity: Schizophrenia tends to run in families. If a parent has the disorder, the offsprings are susceptible to the disease.
