Answer:
When water falls and seeps into the ground it actually interacts with the lithosphere
Answer:
Damaged muscle tissue is replaced by fibrous scar tissue. This is called as 'Fibrosis'. Thicker than the surrounding tissue, scar tissue is paler and denser because it has a limited blood supply; although it takes the place of damaged or destroyed tissue, it is limited in function, including movement, circulation, and sensation.
Dense irregular connective tissue contains fibroblasts scattered amongst randomly oriented collagen fibers, whereas muscular tissues contain multinucleated muscle cells that are able to contract upon stimulation. Because the connective tissue cells cannot contract, the muscle will lose strength, and so muscle function will become impaired.
Answer:
1. Roots: anchor the plant in soil and absorb water and minerals
2: Stem: Holds the plant upright and bear leaves, branches and fruits.
3. Leaves: Carry out photosynthesis to make food for other plant parts.
4. Flower: serves as organ of reproduction to maintain the continuity of the species.
Explanation:
1. Roots: The cells of roots are specialized to penetrate the soil deep to anchor the plant and absorb water and minerals for nutrition of plants.
2: Stem: The cells of stem impart mechanical strength to keep the plant upright and bear leaves, branches and fruits.
3. Leaves: Cells of leaves have chlorophyll pigment to carry out photosynthesis to make food for other plant parts.
4. Flower: Some of the cells of flowers produce male and female gametes that fuse leading to seed formation. Seed germination maintains the continuity of the species.

The answer is; they provide positional information in the embryo
The hox genes are responsible for determining the head and tail ends of the embryo, and ensuring that the right embryo segments develop appropriately and with the right appendages. Without the hox genes, the embryo (and consequently the body) would become unplanned and abnormalities would occur such as having legs in the antennae section in drosophila sp.
