Answer:
<em>The statement that is incorrect is :</em>
<em>Robert wanted to see if his theory was true that cigarette smoke will influence web-building in spiders.</em>
Explanation:
A theory can be described as a descriptive explanation of a phenomenon which is supported by valid experiments and careful examination of facts. As Robert, has not conducted any experiments nor has proved his study with reference to facts, hence it cannot be considered as a theory.
Robert wanted to see if his observation was true that cigarette smoke will influence web-building in spiders will be the correct statement that could be used.
A letter indicates an articulating surface that is comprised of hyaline cartilage.
<h3>What is
hyaline cartilage?</h3>
- The synovial joints include hyaline cartilage, which facilitates joint motion.
- Chondrocytes and extracellular matrix make up its structure.
- The organization of the extracellular matrix, which determines the biomechanical characteristics of cartilage tissue, is greatly influenced by chondrocytes.
- Hyaline cartilage covers the ends of the bones where they come together to create a joint.
- In a typical healthy joint, this cartilage is bluish white and shiny.
- Its main job is to reduce friction and act as a little cushion between the ends of the bones.

The formula for hydrate indicates the number of water molecules that are attached to each formula unit of the compound. Forexample, nickel (II) sulfate hexahydrate is a green/blue solid that has six water molecules included in the crystal foreach Ni2+and each SO42-ion.Many common minerals are
<h3>What is a hydrate ?</h3>
Any compound containing water in the form of H2O molecules, usually, but not always, with a definite content of water by weight.
- The best-known hydrates are crystalline solids that lose their fundamental structures upon removal of the bound water.
- Hydrates are formed when water and light end natural gases come into contact at certain temperature and pressure conditions

Answer: etiolation of plant growth in shade, with fast growing cell without chloroplasts. Out of shade, cell differentiate again to produce photosynthesising cells
Explanation: It is a subjective decision as to what is ‘best’. Good examples are plant responses to changes in the nutrient supply.
when soil nitrogen is depleted some plants, such as legumes, grow nodules on their roots, with cells that release chemical signals to attract nitogen fixing bacteria.
Lack of light induces etiolation in many plants. New cells elongate and develop without chloroplasts, with rapid cell division exhibiting gravitropism, extending upward. When they grow beyond the shade area, cell differentiation changes again, to produce photosynthesising cells.
