1. In passive transport, what direction do molecules move?

2. In active transport, what direction do molecules move?

Answers

Answer:

In passive transport, substances simply move from an area of higher concentration to an area of lower concentration, which does not require the input of energy. Concentration gradient, size of the particles that are diffusing, and temperature of the system affect the rate of diffusion.

In active transport, the particles move across a cell membrane from a lower concentration to a higher concentration. Active transport is the energy-requiring process of pumping molecules and ions across membranes "uphill" against a gradient.

Explanation:

Passive transport moves molecules from high to low concentration without energy. Energy-driven active transport moves molecules from low to high concentrations.

What is active and passive transport?

The transfer of molecules from higher concentrations to lower concentrations is an example of passive transport, which does not require any amount of energy.

The movement of molecules from a lower concentration to a higher concentration is referred to as active transport. Active transport requires the application of energy.

Types Of Passive Transport

Simple DiffusionDiffusion with Facilitation.Filtration.Osmosis.

Active transport mechanisms include 

AntiportSymport Pumps.Endocytosis.Exocytosis.

If there is moisture in the atmosphere as the front (pictured) comes through, what effect could it have on temperature and weather?
(ANSWER FAST!!)

Answers

Answer:

c)The temperature would decrease and there would be a chance of thunderstorms.

Explanation:

The temperature would decrease and there would be a chance of thunderstorms. So, the correct option is C.

What is Thunderstorm?

A thunderstorm is defined as a storm with lightning and thunder produced by a cumulonimbus cloud, usually producing strong winds, heavy rain, and sometimes hail. Thunderstorms are so called because of the thunderous loud noise they make.

There are three basic elements that lead to the development of thunderstorms: moisture, an unstable atmosphere, and some way for the atmosphere to move where the moisture is necessary to produce thunderstorm clouds and precipitation.

Thus, the temperature would decrease and there would be a chance of thunderstorms. So, the correct option is C.

In an ecosystem, atmosphere is a sphere in  the Earth system  which is also part of the hydrosphere.

What is an ecosystem?

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

F. Photosynthesis
G. Cellular respiration
H. DNA replication
J. Protein synthesis

Answers

Answer:

F. Photosynthesis

Explanation:

The organelle pictured (a chloroplast) seems to be absorbing energy from the sunlight and that is included in the process of photosynthesis.

The carbohydrates (glucose) are formed by the process of photosynthesis in the chloroplast of the cell which then sent to the mitochondria for the production of ATP through glycolysis. Thus, the correct option is F.

What is Photosynthesis?

Photosynthesis is the process of conversion of light energy (sunlight) into chemical energy (glucose). This process takes place in the chloroplast of plant cell where chlorophyll is present, this pigment (chlorophyll) is responsible for trapping the sunlight which is responsible for conduction of photosynthesis.

The products of photosynthesis (glucose) is sent to the mitochondria of cell for the production of ATP by the process of glycolysis. This ATP is then utilized by the cell in other cellular mechanisms.

Therefore, the correct option is F.
