A valve is a device or NATURAL object that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or SLURRIES) by opening, closing, or partially OBSTRUCTING VARIOUS passageways. Valves are TECHNICALLY fittings, but are usually discussed as a separate category. In an open valve, fluid flows in a direction from higher pressure to lower pressure. The word is derived from the Latin valva, the moving part of a door, in turn from volvere, to turn, roll.

A cephalopod (/ˈsɛfələpɒd, ˈkɛf-/) is any member of the molluscan class Cephalopoda (Greek plural κεφαλόποδες, kephalópodes; "head-feet")[2] such as a squid, octopus, cuttlefish, or nautilus. These exclusively marine ANIMALS are CHARACTERIZED by bilateral body symmetry, a prominent head, and a set of arms or tentacles (muscular hydrostats) modified from the primitive molluscan foot. Fishermen SOMETIMES call CEPHALOPODS "inkfish," referring to their COMMON ability to squirt ink. The study of cephalopods is a branch of malacology known as teuthology.

ong>Answer:

Plant parenchyma is classified into 4 shapes: polyhedral, stellate, elongated, and lobed. In animals, parenchymal cells are the functional cells within the organism. This does not include those that have structural and/or protective functions like bone cells that make up a skeleton.

Parenchyma is the tissue made up of cells and intercellular spaces that fills the INTERIOR of the body of a flatworm, which is an acoelomate. This is a SPONGY tissue also known as a mesenchymal tissue, in which several TYPES of cells are lodged in their EXTRACELLULAR MATRICES.

rong>Chromosomes are described as follows:

Explanation:

• Chromosomes are described as structures present inside the nucleus of the cell.

• Each CHROMOSOME has specific genes on a particular chromosome.

• The genes contain DNA.

• Hence, each chromosome contains certain amount of genetic material.

• Apart from DNA, chromosomes are also made up of histones.

• Hence, chromosomes carry out HEREDITARY information.

• Each SPECIES carry out specific NUMBER of chromosomes inside each cell.

glucose is converted into insoluble starch and LATER into soluble sugar i.e. sucrose, which is transported in SOLUTION through the phloem in the veins of the leaf and down through the phloem of the STEM. Stoma: The main function of stoma is to let in carbon DIOXIDE from the ATMOSPHERE for photosynthesis.

rong>Lysosomes are known as suicidal bags because of the following reasons:

Explanation:

• Lysosomes are called suicide bags of the cell because lysosomes cause lysis of the DAMAGED cell.

• Lysosomes have digestive ENZYMES known as lysozyme.

• The lysozyme DIGEST their own cells in response to injury or INFLAMMATION.

• Lysosomes can also burst and destroy the cell.

• Due to this reason, lysosome are commonly referred to as suicidal bags or suicidal SACS of a cell.

LIVING organisms are divided into five kingdoms:

Prokaryotae

Protoctista

Animalia

ong>Answer:

researchers thought protein was the genetic material because; proteins were macromolecules with great heterogeneity and functional specificity. Little was known about nucleic ACIDS. The physical and chemical properties of DNA seemed too uniform to account for the multitude of inherited traits.

So, which was the genetic molecule housing all the hereditary information? MANY scientists of the day actually thought it was protein because there are 20 different amino acids for building a protein polymer, while DNA polymers are made of only four NUCLEOTIDE bases.

t now seems certain that RNA was the first molecule of HEREDITY, so it evolved all the essential methods for storing and expressing genetic information before DNA came onto the SCENE. However, single-stranded RNA is rather unstable and is easily damaged by enzymes.
