answer:
our sun will never become a neutron star.
explanation:
- neutron stars are born from suns that are 10-20 times the size of ours.
- in 5 billion years our sun will become a red giant and then eventually a cold white dwarf which is similar to a neutron star, just much larger and much less dense.
The answer would be dominant
Answer:
b. intracellular fluid moves to the outside of cells
Explanation:
The presence of an excess of sodium ions in the extracellular fluid would make it hypertonic with respect to the intracellular fluid. The concentration gradient would drive the intracellular fluid towards the outside of the cell to balance the concentration of the fluids on either side. The passive movement of fluids occurs across the cells and is driven by the concentration gradient only. The biological membranes are permeable for fluid movement such as the movement of water across it.
Answer:
b. they require more oxygen per unit of volume.
Explanation:
Large animals have a specialized organs for exhalation and inhalation of gases due to the requirement of large amount of oxygen for cellular respiration. Respiration is a process in which energy is released in the form of Adenine tri phosphate (ATP) in the mitochondria of the cell with the addition of oxygen. The waste product such as carbondioxide is produced which is removed from the body body through lungs.
