All elements of a ecosystem work together, the sun provides sun light which plants use photosynthesis for food. Small animals eat the producers aka the plants. Then other animals eat those. And so on if a plant wasn't alive then the whole ecosystem will fail.
Answer:
For the energy to be released from the ATP molecule it must first take place that the bond holding the third phosphate molecule must be broken.
Explanation:
The ATP molecule is the one that provides energy with which living beings carry out their metabolic processes.
ATP has in its structure three phosphate molecules, each of them united by a high energy bond. When the hydrolysis of ATP occurs —releasing a phosphate molecule and leaving ADP— <u>energy is released by breaking the bond</u>. That energy is used by the cell to perform its functions.
The other options are not correct because:
- <em>The addition or gain of phosphate to the ADP is called phosphorylation, and it does not release energy.
</em>
- <em>The separation of a phosphate molecule from ATP is sufficient to produce energy.</em>
White blood cells fight infections from bacteria, viruses, fungi. and other pathogens (organisms that cause infection). One important type of white blood cell is the neutrophil. These cells are made in bone marrow and travel in the blood throughout the body. They sense infections, gather at sites of infection, and destroy the pathogens.
When the body has too few neutrophils, the condition is called neutropenia. This makes it harder for the body to fight off pathogens. As a result the person is more likely to get sick from infections. In general, an adult who has fewer than 1,000 neutrophils in a microliter of blood has neutropenia.
If the neutrophil count is very low, (fewer than 500 neutrophils in a microliter of blood), it is called severe neutropenia. When the neutrophil count gets this low, even the bacteria normally living in a person's mouth, skin, and gut can cause serious infections.
Answer:
A
Explanation:
There are different mechanisms for transport of molecules across the cell membrane. One kind of this transport is facilitated diffusion, this is a form of passive transport, not requiring any ATP (the opposite would be active transport, where it does require ATP.
Simple diffusion does require special transport proteins, and neither does osmosis. Filtration is a technique used for sterilisation of water, where any impurities can be drawn out of the liquid
Myosin and actin protein filaments attach to each other . Calcium ions release into myofibrilles . Myosin filaments pull on the actin filaments
