The right answer is B) gene.
A gene, in genetics, is a basic unit of heredity which in principle predetermines a specific trait of the form of a living organism, as defined in 1909 by Wilhelm Johannsen. From the physical point of view, a gene is a fragment of the determined locus of a DNA sequence.
A gene "parameter" the synthesis of a given RNA, by predefining its structure and, therefore, that of the possible protein or possible polypeptide synthesized from this RNA: this is what molecular biology studies .
These two aspects of the notion of gene are supposed to correspond, one at the physical and molecular level, the other at the level of principle and heredity.
Enzymes are protein molecules which serve as catalysts for chemical reactions. A catalyst is a substance which will decrease the activation energy for a reaction. ... Enzymes will make reactions occur much more easily, quickly and more efficiently than they ever would without the enzyme.
Answer:
Chloroplasts - green structure found only in plants cells
Golgi Apparatus - packages and moves proteins
Semi-permeable membrane - outer layer of animal cell, controls movement in and out of the cell
Endoplasmic reticulum - has smooth and rough types
Ribosomes - synthesize proteins
Cell wall - outer layer of plant cell and provides support
The semi-permeable membrane can also be called plasma membrane.
Answer:
1 All living organisms are made up of one or more cells.
2 The cell is the basic structural and functional unit of life.
3 Cells arise from pre-existing cells.
Explanation: if this is not correct plz tell me and ill do some more research but im pretty sure its correct.
The correct answer here is "cell membrane". Generally it makes sure that nothing enters or leaves the cell, except by its highly guarded "gates", such as ion channels, that let some particles through - but they're very picky about whom to let in!
