Why does a cell use less energy to move things when they are small?

Answers

Answer 1

Because they don’t have to move quickly because it’s a smaller space.

Explanation:

When a cell moves quickly they are trying to take up space. So if the cell is moving in a small space then they would use less energy

Answers

Calcium signaling is the use of calcium ions (Ca2+) to communicate and drive intracellular processes often as a step in signal transduction. Ca2+ is important for cellular signalling, for once it enters the cytosol of the cytoplasm it exerts allosteric regulatory effects on many enzymes and proteins.

Answer:

Calcium signaling is the use of calcium ions (Ca2+) to communicate and drive intracellular processes often as a step in signal transduction. Ca2+ is important for cellular signalling, for once it enters the cytosol of the cytoplasm it exerts allosteric regulatory effects on many enzymes and proteins. Ca2+ can act in signal transduction resulting from activation of ion channels or as a second messenger caused by indirect signal transduction pathways such as G protein-coupled receptors.

If an egg is fertilized by a sperm carrying the X sex chromosome, the zygote will have one pair of X chromosomes that will determine the female sex in the product.

How does mitochondria help the cell get the material it needs

Answers

Answer:

Known as the “powerhouses of the cell,” mitochondria produce the energy necessary for the cell's survival and functioning. Through a series of chemical reactions, mitochondria break down glucose into an energy molecule known as adenosine triphosphate (ATP), which is used to fuel various other cellular processes.

The reactants for photosynthesis are carbon dioxide, water and sunlight (light energy).

Give two uses of energy transferred by respiration in eukaryotes

Answers

Answer:

Most aerobic respiration takes place inside mitochondria. Some of the energy released in respiration is used to make larger molecules from smaller ones, to enable muscles to contract and to keep temperature steady. Some of the energy released in respiration in plants is used to make amino acids and proteins.

Explanation:google said it and i had this question in my science class and got it right

The uses of energy are - energy for metabolic reaction and growth and development of cells.

Cellular respiration provides energy with the series of complex chemical reaction cycles that is used for:

Working your muscles - for movement and physical activities energy is required.Growth and repair of cells - dividing cells, repairing them and development of the cells also require energy.Building larger molecules from smaller ones for instance proteins from amino acids.Allowing chemical reactions to take place.Absorbing molecules in active transport.

Thus, The uses of energy are - energy for metabolic reaction and growth and development of cells.

What is an experiment?

An experiment is a technique used to confirm or deny a hypothesis, as well as assess the likelihood or effectiveness of something that has never been tried before. Experiments show what happens when a specific factor is modified, which sheds light on cause-and-effect relationships.

The three primary categories of scientific experiments are quasi-experimental, observational, and experimental (non-experimental). The most rigorous type of scientific investigation is experimental, often known as randomized control. The most control is present, as the name would imply.

Data are the facts and the observations gathered in an experiment.  Therefore, option B is correct.

If carbon dioxide was removed from a plant's environment, what would you expect to
happen to the plant's production of sugars?
O fewer sugars will be produced
more sugars will be produced
O carbon dioxide does not affect the production of sugars in plants
o the same number of sugars will be produced but without the carbon dioxide

Answers

Answer: Fewer sugars will be made because plants use carbon dioxide in photosynthesis.

Hope this helps

Plants are autotrophs, which prepare their food in the presence of sunlight, water, and carbon dioxide to yield sugar and oxygen.

The carbon dioxide is removed from the plant's environment, then less sugar will be produced.

Photosynthesis is a metabolic process in which plants prepare food in the presence of sunlight, carbon dioxide, and water. The products of photosynthesis are oxygen and sugar molecules.

The carbon dioxide if removed or reduced from the plant's environment, then the plants will be unable to perform photosynthesis properly, and in the limited resources, the products formed will be reduced.

Thus, the correct answer is Option A.
