Why do cells need to use active transport?
Cells use active transport to move substances against their concentration gradient or across a membrane with the help of energy from ATP. This process is necessary for the cell to maintain proper internal conditions, such as ion balance and nutrient uptake, which are essential for its survival and functioning.
Do eggs dissolving in vinegar represent active transport or passive transport?
I assume you're referring to the simple experiment where the shell is softened using vinegar (acetic acid) and then placed in water. Water moves into the egg cells via osmosis (passive transport) til the cells rupture
Short answer: Passive (Osmosis)
How are plant hormones transported?
Plant hormones are transported through the plant by a combination of diffusion and active transport processes. They can move through cell walls, cell membranes, and the plant's vascular system to reach target tissues. Different hormones use different transport mechanisms depending on their chemical properties and target locations within the plant.
Which size of cell is most efficent at transporting nutrients?
Small cells are more efficient at transporting nutrients because they have a larger surface area-to-volume ratio, allowing for quicker absorption and exchange of nutrients. This means that nutrients can enter and exit the cell more rapidly, benefiting the cell's metabolic processes.
Is mineral movement into plant root an active transport or passive transport?
Mineral movement into plant roots is typically an active transport process. It requires energy to move minerals against their concentration gradient from the soil into the plant roots. Transport proteins such as pumps or carriers are involved in this process to facilitate the movement of minerals into the plant.
Why is your transport system called a double circulstory system?
The double circulatory system refers to the two loops that the blood follows in the circulatory system. The first loop is the systemic circulation, where oxygenated blood is pumped from the heart to the body tissues and deoxygenated blood is returned to the heart. The second loop is the pulmonary circulation, where deoxygenated blood is pumped from the heart to the lungs for oxygenation and then returned to the heart.
What transports secondary oocyte toward uterus?
The fallopian tubes transport the secondary oocyte from the ovary toward the uterus. This process is facilitated by ciliary movement and muscular contractions within the fallopian tubes, which help propel the oocyte towards the uterus for potential fertilization.
What happens in the movement of molecules in passive transport?
In passive transport, molecules move across a cell membrane from an area of higher concentration to an area of lower concentration, driven by the concentration gradient. This process does not require energy input from the cell. Common types of passive transport include simple diffusion, facilitated diffusion, and osmosis.
Solar energy is important because it is a renewable and sustainable source of power that helps reduce greenhouse gas emissions and dependence on fossil fuels. it also helps in lowering electricity costs and can be used to power homes, businesses, and even entire communities.
What is the best way to transport cupcakes?
This is very tricky. You can buy specialist cupcake boxes (these can be found easily on ebay- where I find they are the best value) but this does not guarantee theicing/ decoration on top will not be damaged by the box being turned upside down etc. In general it is best to deliver cupcakes by hand where you can ensure their safety.
What types of things do bridges help transport?
Bridges tend to be viaducts or aqueducts. (These names are derived from Latin).
A viaduct carries a road or a rail track, and is used by, respectively, road or rail vehicles.
An aqueduct carries water. This might be a fairly small stream, carrying water from a reservoir to a town; but a large aqueduct can carry a canal on which boats and barges can travel.
The ancient Romans build some famous viaducts for water supply; and in England a number of the canals built during the Industrial Revolution used magnificent aqueducts to cross valleys.

What is the most popular form of transport in Italy?
You can typically expect to receive your T4 slip from your employer by the end of February of the following year. Employers are required to provide T4 slips to their employees by this deadline for the previous calendar year’s earnings. If you haven’t received it by then, you should contact your employer’s payroll department. Additionally, you can check your online account with the Canada Revenue Agency (CRA) for electronic copies.
Why do cells need to use transport proteins to function?
Carbohydrates cannot pass directly through the cell membrane.
some important molecules are too large to pass through the cell membrane
