D) Use a reusable grocery bag- less plastic bag waste
Answer:
A
Explanation:
Each of the other options can change the land structure
Answer: <u>B. They signal phagocytes
</u>
Explanation: Complement proteins are a part of immune system of the body. These are plasma proteins which help in the process of marking and killing the pathogens. These are not involved in the fever causing mechanism, so option D is incorrect. Also, these are not carrier proteins, and are not associated with hormones, thus option C is also incorrect. Since these proteins bind with the pathogens and make them easily recognized by the phagocytes, option B is the right answer.
The Ptolemy's theory of the solar system was disproved by the discovery of the new information. The Ptolemy's theory stated that the Earth is at the center of the solar system and all the planets, suns and stars orbited around it while the Earth stayed completely stationary. However, this theory was proven to be false as the sun-centeric model of the solar system better explained various phenomenon, such as the particular movement of the planets.
Hence, the correct answer is 'Ptolemy's theory of the solar system'.
Answer:
The correct answer is -
1. stomata - openings that are most frequently found on the underside of a leaf.
2. Palaside layer - the layer in the leaf that is the primary spot of photosynthesis.
3. spongy layer - the layer within the leaf that has many holes and spaces for gases to exchange.
4. cuticle - the waxy protective coating on leaves.
5. epidermis - the outer layer of cells on leaves that has a waxy coating.
Explanation:
The structure of leaves has various layers and structures in it for specific functions.
Epidermis - it is the outermost protective layer of the leaf that has a waxy coating known as the cuticle.
Cuticle - it is a waxy coating that provides protection to the plant leaves and prevents moisture to move out of the cells.
Palisade layer - it is the closely packed photosynthetic pigments chlorophyll layer known as the primary spot for photosynthesis.
Spongy layer - it is the layer that has loosely packed photosynthetic cells and allows the gaseous exchange as their many small holes and spaces.
Stomata - Stomata is the holes or openings that are most frequently found on the underside of a leaf that allows for gaseous exchange.
