Proteins are not responsible for global warming. That's greenhouse gases, which are an entirely different kind of chemical. There are also millions of other things that proteins are not responsible for. Why do people always want to blame the proteins? It's so unfair.Sending Nerve Impulses
A chemical property is the substance's response to other substances, resulting in a new substance. A physical property is something like a substance's lustre, melting point, boiling point, colour, or density, to name a few. Examples of chemical properties are: combustibility and reaction to acid.
False
Not necessarily. There's something called the enthalpy of mixing which can be responsible for lowering the temperature when two substances are mixed even if no chemical reaction occurs. It may also be an endothermic reaction; if there are other signs of a reaction (formation of a precipitate, evolution of a gas, color change, etc.) then it probably is a chemical reaction.
The flexibility of a material is known as pliability. The opposite of this is stiffness, or the resistance to outside applied forces.
Sclerenchyma have long columns of cells, each cell is thick. The end walls of sclerenchyma are often perforated (contain holes). Xylem and phloem are often surrounded by layers of sclerenchyma
Luciferon was the chemical responsible to it.
The nuclei is not visible in the sclerenchyma tissue at maturity because the cells are usually dead.
It is a dead tissue. Sclerenchyma occurs over vascular bundles, hypodermis of monocot stems, veins of leaves and hard covering seeds and nuts.
Valence electrons are responsible for chemical boding.
Sclerenchyma
The chemical responsible for genetic information in a cell is DNA
Sclerenchyma cells are the dead cells and they are devoid of protoplasm.The walls of Sclerenchyma are greatly thickened with deposition of lignin. Such cells are called lignified.Due to excessive thickening of the walls of sclerenchyma cell, its cell cavity or lumen is nearly absent.
Collenchyma tissue composed of polygonal cells includes parenchyma, collenchyma, and sclerenchyma.
The chemical mainly responsible for growth and repair is Protein.
Sclerenchyma
A stem requires more strength and structure, which sclerenchyma and collenchyma provide, than leaves.
