Active transport is a type of cellular transport that requires energy in the form of adenosine triphosphate (ATP) to move substances against their concentration gradient, from lower to higher concentration. This process enables cells to take up essential nutrients, excrete waste products, and maintain proper ion concentrations.
What does not affect the rate at which a solid solute dissolves?
Increasing the pressure over a solid solute has virtually no effect on the rate that it dissolves. Stirring and increasing the temperature are the best methods for increasing the rate at which a solid solute dissolves.
Do plants that are not green make food?
non-green or non-sun plants can get their food/energy (ATP) from:
1. glycolosis
2.bridging pathway (puyruvate to CoA
3.Krebs cycle (or CAC/citric cycle)
4.electron transport
2,3,&4 are activities of the mitochondria and need oxygen to be performed.

Why does an iceberg float in the ocean?
An iceberg floats in the ocean because it is less dense than the water it displaces. Ice has a lower density than liquid water because of its crystalline structure, which allows it to float on the surface.
What are the two imaginary lines that divide the earth in half?
The two imaginary lines that divide the earth in half are the Equator (divides the earth into Northern and Southern Hemispheres) and the Prime Meridian (divides the earth into Eastern and Western Hemispheres).
What is the distance around the earth at the equator in miles?
The circumference of the earth at the equator is 24,901.55 miles (40,075.16 kilometers). But, if you measure the earth through the poles the circumference is a bit shorter - 24,859.82 miles (40,008 km). This means the earth is a tad wider than it is tall, giving it a slight bulge at the equator. This shape is known as an ellipsoid or more properly, geoid (earth-like).
The force that pulls objects toward one another?
The force that pulls objects toward one another is gravity. This force is proportional to the masses of the objects and decreases with distance.
Do cameras have concave or convex lenses?
Cameras typically use convex lenses to focus light onto the image sensor or film. Concave lenses are not commonly used in cameras because they cause light to diverge rather than converge, making them unsuitable for image formation.
What kind of temperatures does a tropical zone have?
Tropical zones typically have warm to hot temperatures, with average temperatures ranging between 20°C to 30°C (68°F to 86°F). These regions experience minimal temperature variations throughout the year due to their proximity to the equator and receive high levels of solar radiation.
The term that describes the ability of many metals to be pounded into thin sheets?
malle·a·bly adv.
Synonyms: malleable, ductile, plastic, pliable, pliant
These adjectives mean capable of being shaped, bent, or drawn out: malleable metals such as gold and silver; ductile copper; a plastic substance such as wax; soaked the leather to make it pliable; pliant molten glass.
The main idea of writing a science project to determine which solution freezes the fastest (plain water, salt water, sugar water) is to investigate the impact of different solutes on the freezing point of water. By conducting experiments and analyzing data, students can learn about the concept of freezing point depression and how solutes affect the physical properties of a solution.
What is the color of aluminum?
Al is a metal, and its color is metallic (you might wish to call it a 'bright grey' or 'silvery'), because the freely movable conduction electrons represent a good mirror for incoming light.
How do you find the speed of a object?
Speed is an absolute unchanging linear distance crossed per unit time. Speed is not the same thing as velocity, and an object cannot exhibit a "rate of speed" since rate is velocity. Speed is determined by measuring the distance traversed over a specific unit of time. Since the object almost always is not at a constant speed, we are really estimating the average speed.
Some examples of liquids include water, milk, juice, and alcohol. Liquids have a definite volume but take the shape of their container.
How did the thermal energy of the cookies transfer to the counter?
The thermal energy of the hot cookies transferred to the cooler counter through a process called conduction. When the cookies were placed on the counter, heat energy moved from the cookies to the counter as they came into direct contact, causing the counter to warm up.
Its commonly referred to as hazardous waste or toxic waste.
A force that pulls objects towards eachother?
Gravity is the force that pulls objects towards each other. It is a fundamental force of nature that causes objects with mass to be attracted to each other.
What is the displacement of water?
When objects cannot be easily measured with a ruler water displacement is used to measure the objects volume. Water displacement measures the amount of water that is displaced, or moved. The amount that the waster rises is mL indicates the volume of the object in Cm3
What is the direction of a shadow?
A shadow is formed in the opposite direction of the light source. For example, when the light source is behind an object, the shadow is cast in front of the object.
What causes the ice to change to water as they pass the block round from hand to hand?
The heat from their hands transfers to the ice, causing it to melt and change from a solid to a liquid state (water). The increased temperature breaks the bonds holding the ice molecules together, allowing them to move more freely and flow as liquid water.
How does the sun affect the weather?
The sun, the closest star of the sky, is more than our source of light. It provides heat, energy and acts as the main engine driving the atmosphere on our planet. The sun generates temperature variations so that basically, every weather phenomenon available on earth can be traced to the sun.
The sun typically warms up the earth unevenly due to the earth's natural tilt at an angle of 23.5 degrees which causes the areas near the equator to be warmed up much more than the Poles. This causes the major climate differences we see between the equatorial areas typically mildly temperated and the Polar regions extremely gelid. The earth's natural tilt is also what causes weather and climate differences throughout the year known as seasons.
The sun plays a primary role in affecting weather patterns on earth, here are a few examples:
-When the sun warms up air, the area encompassing this warm air in meteorology is known as a warm front. Many weather phenomenons occur when a warm front meets a cold front.
-The sun will warm up the earth's surface and this warm air will expand and rise, as it rises, the air will then cool and descend. This up and down cycle of rising warm air and descending cool air will generate a weather phenomenon known as wind.
-The sun will warm up air over the sea near the equator and this warm air will rise creating a cloud. Cold air will then replace the warm air that has lifted and the clashes between cold and warm air will be creating spiraling turbulence known as a hurricanes.
-The sun creates warm air which then abruptly turns cold, this creates pressure and turbulence which whips up a tornado.
-The sun warms up the ocean's, lake's and soil's surfaces causing warm air to rise in the athmosphere up to a point where it will meet colder air causing it to condense and generate clouds that in turn, will produce rain, hail or snow. This is know as the water cycle which is fundamental for all living beings on earth.
In the past, people thought that the closest you could get to the sun the warmer it would be. This is actually untrue. If you climb to the top of a mountain you will likely feel a dramatic climate change. This is because as warm air rises it tends to cool, therefore, making mountain tops often cold and capped with snow.
As seen, the sun plays a primarily role on affecting the weather patterns on earth. However, recently the sun has also been perceived as a main contributing factor of global warming. HEHE
How many red blood cells are made each day and where are they made?
The are made in bone marrow or the spongy bonepart of the bone. Look in your science book to double check!
What type of energy is a burning match?
A burning match produces thermal energy, in the form of heat and light, due to the combustion reaction of the match head with oxygen in the air.
This is called static electricity. When you rub your feet on the rug, electrons are transferred from the rug to your body, creating a charge imbalance. When you touch a doorknob, the excess electrons on your body are discharged, creating a spark.
