Answer: phagocytosis; lysosomes
Collar cells in the sponge digest food through phagocytosis or by using enzymes that come from the lysosomes. Bacteria are among the elements that are broken down by phagocytosis with the help of some specific enzymes found in lysosomes.
The number of molecules in some water isn't affected by changing its temperature. But to know if you have the same number of molecules in two water samples, you need to compare their masses, not their volumes. When you heat some cool water, it expands. (When you slightly warm some ice-cold water, it contracts a little, but let's keep this simple.) So hot water takes up more space than cold water. The amount of space something takes up is called volume. If you were to have 2 cups of water, one of hot water and one of cold water with equal volumes, the cold water would have more molecules.
<span>Hot and cold water are made of the same type of molecules. Each molecule has one oxygen and two hydrogen atoms. The difference between them is the speed of the molecules jiggling around. </span>
Each male and female sex cell has 46 chromosomes in it. The number of chromosomes are reduced to half(23), so that when the sex cells combine, they also add up to 46(23+23). If the chromosomes did not reduce to half, the number of chromosomes would be off balance and the gamete would not survive.
Answer:
by osmisis
Explanation:
from region of high water potential to one with low water potential
Answer:
The correct answer is a. where it reproduce
Explanation:
Lizard is a reptile and salamanders are amphibians and they both reproduce in different way. Female amphibians mainly lay their fertilized eggs in water, therefore, the reproduction in amphibians takes place in water and moist area not on land.
The eggs of amphibians are not covered from the shell and they have a larval stage which have gills to respire in the water. While lizards are reptiles that lay eggs on land because their shells have a protective outer shell of calcium carbonate.
Therefore difference in reproduction behavior best distinguishes the saladizard as either a lizard or a salamander. So the correct answer is a.
