Cohesion, adhesion and surface tension are different from each other. Adhesion is used in xylem. Surface tension enables an insect to sit on water.
<u>Explanation:</u>
The force of attraction between the molecules of the same type is called cohesion. The force of attraction between the molecules of different type is called adhesion. Tendency of fluid surfaces to shrink to minimum possible area due to the attraction between the liquid molecules is called surface tension.
Adhesion is used in xylem. In xylem water molecules move from the roots to different parts of the plant through the xylem tubes. The adhesive force between the water molecules and xylem walls make the movement of water possible.
Surface tension enables an insect to sit on the surface of a liquid. Due to surface tension the water surface stretches like a membrane due to the higher attractive force between the water molecules.
Assuming that you're referring to forest ecosystem, the two ecological benefits of this ecosystem are :
- it provides habitats for many organisms
- It provide Oxygen supply for the world
<span>The way to do this is called Civil Disobedience
Martin Luther King Jr. described this as hatred and contempt for the law. It mostly involves telling the government no in subtle ways that does not involve violence resistance and peaceful demonstrations . usually it takes certain of such steps before governments can reverse certain policies that are unfavorable to her citizens.</span>
Answer:
2 in 4
Explanation:
If a female cat with orange fur (XOXO) is crossed with a male cat with black fur (XoY) then:
P: XOXO x XoY
F1: XOXo XOY XOXo XOY
This means that half of the offspring will be females with tortoiseshell color (XOXo) and other half of the offspring will be males with orange fur (XOY).
Answer:
Due to different pigments.
Explanation:
The multicellular algae are red, green and brown because of the presence of pigments. The red algae are red in colour because of the presence of the phycoerythrin which is a type of pigment. This pigment reflects red light due to already presence in its body and absorbs blue light that is necessary for photosynthesis process. The brown algae contain fucoxanthin pigment and green algae contain xanthophylls pigments that are responsible for its colour so we can conclude that these different types of pigments are responsible for the different colour of algae.
