Which processes in the water cycle are driven by the force of gravity? Explain how you know.
Answers
Answer:
pls mark me as brainliest
Explanation:
Gravity causes precipitation to fall from clouds and water to flow downward on the land through watersheds. Energy from the sun and the force of gravity drive the continual cycling of water among these reservoirs. As the water is heated, it changes state from a liquid to a gas. This process is called evaporation.
Gravity causes the precipitation to fall downwards towards the earth. Gravity also directs the movement of water through the turning points.
What is the water cycle?Water is found in three states on Earth. Ice as solid, water as liquid, and steam as gas. The change in the state of water occurs by loss or gain of energy.
When the water absorbs the energy of sunlight, it turns from liquid to vapors. This is called the evaporation of water. The evaporation results in vaporization.
The vapors turn back to liquid when their temperature drops. This process is called condensation. When the temperature of the liquid also drops, it turns to solid ice. This is called freezing.
The energy source for the water cycle is sunlight. The propelling force for the water is gravity. Gravity pulls the rain of precipitation down to the earth from the clouds.
The movement of air according to its density and the movement of ocean water are all possible due to gravity.
Therefore gravity plays an important role in the water cycle.

Answers
Answer:
One way that the world’s ocean affects weather and climate is by playing an important role in keeping our planet warm. The majority of radiation from the sun is absorbed by the ocean, particularly in tropical waters around the equator, where the ocean acts like a massive, heat-retaining solar panel. Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds. In fact, almost all rain that falls on land starts off in the ocean. The tropics are particularly rainy because heat absorption, and thus ocean evaporation, is highest in this area.
Major current systems typically flow clockwise in the northern hemisphere and counterclockwise in the southern hemisphere, in circular patterns that often trace the coastlines.
Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics.
Explanation:
One way that the world’s ocean affects weather and climate is by playing an important role in keeping our planet warm. The majority of radiation from the sun is absorbed by the ocean, particularly in tropical waters around the equator, where the ocean acts like a massive, heat-retaining solar panel. Land areas also absorb some sunlight, and the atmosphere helps to retain heat that would otherwise quickly radiate into space after sunset.
The ocean doesn't just store solar radiation; it also helps to distribute heat around the globe. When water molecules are heated, they exchange freely with the air in a process called evaporation. Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds. In fact, almost all rain that falls on land starts off in the ocean. The tropics are particularly rainy because heat absorption, and thus ocean evaporation, is highest in this area.
Outside of Earth’s equatorial areas, weather patterns are driven largely by ocean currents. Currents are movements of ocean water in a continuous flow, created largely by surface winds but also partly by temperature and salinity gradients, Earth’s rotation, and tides. Major current systems typically flow clockwise in the northern hemisphere and counterclockwise in the southern hemisphere, in circular patterns that often trace the coastlines.
Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth’s surface. Without currents in the ocean, regional temperatures would be more extreme—super hot at the equator and frigid toward the poles—and much less of Earth’s land would be habitable.

Mark plans and prepares the meals for a local Head Start program that serves approximately seventy-five 3- and 4-year-olds. He has explored and likes the new MyPlate guidelines and wants to use several features when he develops his weekly menus for the coming school year. He is especially interested in including a greater variety of fruits and vegetables for the children to try and incorporating more plant-based proteins and ethnic foods into his meals. Mark and the teachers have fenced off a corner of the play yard where the children will be able to plant a garden when they return in the fall. They also worked together over the summer to design weekly lesson plans around featured foods and have decided to concentrate on colors during the first month.
How should the menu planner respond to children’s refusal to eat a new food(s)? Should these items be eliminated from future menus? Why or why not?
Answers
The menu planner must respond to children's refusal to eat a new food by introducing foods in gradual and diverse ways, looking for strategies to make the children's experience more playful.
Items that children are less likely to try should not be removed from future menus, but should be implemented in a way that accepts those foods.
The menu planner must therefore establish a plan to introduce healthy eating to children through knowledge of each food, explanation of benefits, integrative tasks and activities, diversified recipes, etc.

The traits of a living organism are the result of complex interactions of chemical components that make up the living organism. Proteins do much of the chemical work inside cells, so they largely determine an organism’s traits. What components are responsible for providing the genetic code that determines how proteins are built and, therefore, how they determine traits?
Answers
The components responsible for providing the genetic code that determines how proteins are built and, therefore, they determine traits are the nitrogen bases of nucleotides in the DNA molecule.
What are the nitrogen bases of nucleotides in the DNA molecule?Nitrogen bases of nucleotides in the DNA molecule are small subunits of these building blocks of the genetic material. In DNA, a nucleotide is composed of three different subunits which are the nitrogen bases, the sugar ribose and a phosphate group.
There are four types of nitrogen bases which are called adenine or A, guanine or G, cytosine or C, and thymine of T.
Therefore, with this data, we can see that nitrogen bases of nucleotides in the DNA molecule are four (A, C, G and T) and they are building blocks of the nucleotides that form the genetic material of an organism cell.

When the smooth/rough endoplasmic reticulum sends out the proteins to the Golgi Apparatus using vesicles as the "delivery trucks" the golgi apparatus modifies them with enzymes and then sorts and sends them to where there are needed. Does the golgi apparatus use vesicles to do that? Thanks so much!
Answers
The golgi apparatus is involved in sorting and sending the proteins involved in cellular functions. For this purpose, golgi apparatus uses specific vesicles for the transport of substances to their target destinations.
What is Golgi Apparatus?
The Golgi apparatus also known as Golgi complex is an organelle found in the eukaryotic cells. It functions as a factory in which proteins received from the Endoplasmic reticulum are further processed and sorted for transport to their eventual destinations such as lysosomes, plasma membrane, or secretion.
In the final stage of transport through Golgi apparatus, the modified proteins and lipids are sorted in the trans Golgi networks and are packaged into vesicles at the trans golgi. These vesicles then deliver the molecules to their destinations, such as lysosomes or the cell membrane.

The seed formed inside the ovary of the flower. As the seed develops in the flower, water is withdrawn from it so that it becomes almost dry. suggest why is it important?
Answers
Water withdrawal from the developing seed inside the flower is important to induce dormancy, enhance longevity, protect against pathogens, facilitate dispersal, and trigger germination under favorable conditions.
Water withdrawal from the seed during its development inside the ovary is crucial for seed dormancy, longevity, protection, dispersal, and germination. Dormancy enables seeds to survive unfavorable conditions. The dry state reduces metabolic activity, enhancing seed longevity. Withdrawing water creates an inhospitable environment for pathogens, safeguarding the seed. Dry seeds are lighter and more easily dispersed by wind, animals, or water, aiding in the colonization of new habitats. Rehydration of the seed after dispersal triggers germination, initiating growth.Overall, water withdrawal from the seed inside the ovary serves as a survival strategy, allowing seeds to endure harsh conditions, remain viable for extended periods, avoid microbial damage, disperse effectively, and germinate when conditions are favorable.
