Answer:
A biome is described as an area of the planet, which is classified on the basis of plants and animals living in that area. Soil, amount of light, temperature, and water are some of the important factors that determine what type of life exists in a biome.
The temperature, vegetation, and precipitation are the important characteristics of the biome.
Examples of biomes include tundra, desert etc.
energy is lost at each level of consumption so it’s simply not efficient to be a 5th + level consumer
Answer: Option A) Exocytosis
Explanation:
Unlike the other pathways mentioned, exocytosis involves the outward movement of outside the cells. This is vital in the removal of waste products generated within the cell.
Thus, exocytosis is the answer because it expels materials out of the cell, rather than deliver materials to lysosomes
Some scientists hypothesize that the eukaryotic cells are really the result of symbiotic processes!
Specifically, the internal organs of the cells could be a remnant of a symbiotic relationship in which one cell lived inside of another cell. These two cells then both split upon reproduction and eventually the cell inside was reduced to an organelle.
But according to this theory, it is very likely that the prokaryotic cells engaged in a number of symbiotic relationship, and that this actually lead to the emergence of eukaryotic cells!

<u>ANSWER:</u>
The muscles and joints allow the hands to perform their function of holding and grasping a wide variety of things.
<u>EXPLANATION:</u>
- The structure of hands is "very delicate and complex". The tendons, nerve fibres, tissues and thin muscles are located right under the skin.
- The bones of the hand including the 4 carpal bones, 5 metacarpal and 14 finger bones are all connected by joints and ligaments and these allow the hand to grasp things.
- The wrist is made of "two parts of a joint" that allow the extension and stretching of hands.
