What differentiates passive transport from active transport?
Group of answer choices
Molecules move down a concentration gradient during passive transport.
Passive transport involves molecules moving across the cell membrane.
ATP is needed for passive transport to occur.
Proteins have a role in passive transport.
Answer:
The movement of molecules across a membrane without the input of energy is known as passive transport. When energy (ATP) is needed, the movement is known as active transport.

What is the elephant getting when the bond is broken in sucrose?
Answer:
The elephant is getting Energy.
Explanation:
The elephant is getting Energy because sucrose is been hydrolysed and the bonds are broken down by enzyme sucrase isomaltase present in the intestine. Inches the bonds are broken, it is broken into glucose and fructose which is absorbed by the small intestine into the blood. The glucose serve as energy source or it is been stored as fly oven in the liver which is later broken down to glucose which is use for metabolic pathways to produce energy.
The elephant gets OXYGEN when the bond is broken in sucrose.
Sucrose is a disaccharide consisting of one glucose unit and one fructose unit, both units are linked by a glycosidic bond. The hydrolysis of sucrose generates a 1:1 mixture of glucose and fructose.The glycosidic bond can be exemplified by the central atom of oxygen that connects both monosaccharides in the sucrose molecule.Sucrase is an enzyme that binds to sucrose and catalyzes its hydrolysis to produce glucose and fructose.In conclusion, the elephant gets OXYGEN when the bond is broken in sucrose.

Explanation:
Arrows have come to represent protection and defence from any evil that can come to you. Sustenance – Arrows were used to fight enemies and to hunt food, two important aspects of sustaining life. As a result, an arrow symbolizes maintaining and protecting life.
REAL NAME - SHRESTH DUBEY
The arrows in a food chain represent the flow of energy or the transfer of nutrients between different organisms in an ecosystem.
They indicate the direction of energy transfer, showing which organism is being consumed by another. The arrow always points from the organism being consumed (prey) to the organism consuming it (predator).
The primary producers, such as plants or algae, are at the beginning of the food chain and transfer energy to herbivores (primary consumers), which are then consumed by carnivores (secondary consumers) or other higher-level consumers.
The arrows help depict the interconnectedness and energy flow within an ecosystem, illustrating the feeding relationships between organisms.

An antibiotic label says to take it for fourteen days. If we stop taking the medication after ten days, what would most likely
happen to the bacteria in our body?
A The bacteria causes the human immune system to stop producing antibodies to fight disease.
B A population of bacteria resistant to the antibiotic appears.
The strain of bacteria allows the human immune system to build up resistance.
The bacteria builds up a resistance to all types of antibiotics, turning into a "superbug".
Answer:
B
Explanation:
This actually happened to me! Since you don't fully kill off all the bacteria, they will mutate and become resistant to the medication. The 14 days ensures that the bacteria will all be killed whereas 10 days allows the stronger organisms to grow and reproduce(where they typically are immune/build an immunity)

A particle of rain water has just reached the ocean. In what order will the particle now complete the following steps of the water cycle?
Answer:
evaporation - condensation - precipitation - surface runoff
Explanation:
For a water particle that has just reached the ocean, the correct order of the water cycle is as follows: evaporation (liquid water changes to water vapor) → condensation (water vapor changes to liquid water) → precipitation (water falls to the Earth's surface) → surface runoff (water travels along the surface of the Earth into a reservoir, such as an ocean). The water cycle is a continuous cycle with no strict beginning or end.

Do you have more cells now than you did when you were five?
Answer:
No After your cell dies of another one come. Your cells are still the same
Explanation:
When you age, cells do divide and reproduce more cells. However when you age the reproduction process of cells gets slower and they can die off before they can reproduce. There can be many problems with your cells that can make cell count lower such as Atrophy, and Dysplasia. When you age, cells are a contributing factor of making you age. They can change your skin, face, etc.. So the answer would be no, you would not have more than you did when you were five.

Both natural processes and human activity are causing some of Earth's permanent bodies of ice to melt. If enough of this ice melts, it will add warm freshwater to the northern Atlantic Ocean, where deep water currents start. What effect is this likely to have
Answer:
EFFECTS - : Melting glaciers and icebergs release fresh water and reduce the salinity of the surrounding sea. The seawater also becomes less dense, changing patterns of ocean currents.
Explanation -
MELTING OF ICE AND ADDING WARM FRESH WATER TO NORTH ATLANTIC OCEAN -: As part of the thermohaline circulation (also called the Global Ocean Conveyor), seawater flows through the Atlantic, the normal pattern by which seawater passes to the oceans of the world. Due to variations in water density caused by differences in temperature and salinity, the water in the Global Ocean Conveyor circulates. Colder water is denser than colder water, while salter water is denser than fresh water or less salty water.
Water heated at the Equator flows north to cold high latitudes at the surface of the ocean, where it becomes colder. When it cools, the deep ocean becomes denser and sinks. To take its place, more warm surface water flows in, cools, sinks, and the pattern continues. But this trend may be modified by melting Arctic sea ice.
The influx of freshwater from the melting ice makes seawater less salty and thus less thick at high latitudes as the Planet begins to warm and Arctic sea ice melts. In reality, data shows that over the past few decades, the North Atlantic has already become fresher.
Answer:
Salinity changes in water
