when an organism of many cells breaks up into two or more parts and these parts survive to produce a new organism , reproduction occurs by fragmentation.
Answer:
Water has several very unique properties, like surface tension, cohesion, and adhesion because water is polar and every water molecule electrically attracts the neighboring water molecules.
Explanation:
Water is a universal solvent and has several unique properties like surface tension, adhesion, cohesion, high specific heat, etc.
In a water molecule, the oxygen atom's nucleus attracts electrons more strongly than the nuclei of hydrogen atoms. The negatively charged electrons are pulled toward the oxygen atom's nucleus and away from the hydrogen atom nuclei. As a result, a negative electrical charge occurs in the middle part of the water molecule near the oxygen atom and a positive charge near the other parts of the molecule (hydrogen atoms). This unequal distribution of electrical charge between different parts of the water molecule (polarity) makes it a polar molecule.
The positive part of one water molecule (hydrogen atoms) is attracted to the negative parts of neighboring water molecules and as a result, hydrogen bonds are formed between hydrogen and oxygen atoms of adjacent water molecules. These hydrogen bonds between molecules help hold water molecules together.
Answer:
1.) Particles in a solid have fixed locations in a volume that does not change. • Solids have a definite volume and shape because particles in a solid vibrate around fixed locations.
2.) It's a process called sublimation. The easiest example of sublimation might be dry ice. Dry ice is solid carbon dioxide. When you leave dry ice out in a room, it just turns into a gas.
Answer:
they are formed in sperm and eggs.
Explanation:
The term chromosome comes from the Greek words for color (chroma) and body (soma). Scientists gave this name to chromosomes because they are cell structures, or bodies, that are strongly stained by some colorful dyes used in research
Hi
Basically, <span>Eukaryotic cells are a fair bit larger than Prokaryotic cells. Of course, if you look at them under the microscope, you can generally see details inside Eukaryotic cells, whereas Prokaryotes are just tiny dots. So, an exact measure doesn't exist, but the first are bigger than the second. </span>
