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.
The slide of stages in starfish development illustrates stages from unfertilized egg to gastrula—typical of echinoderms and chordates that have very little yolk in the egg. Three embryonic cell layers—ectoderm, endoderm, and mesoderm—are established. All adult tissues are derived from these layers.
The mitochondrial matrix is the fluid inside the mitochondria. It is required during cellular respiration.
<h3>What are mitochondria?</h3>
Mitochondria are eukaryotic organelles that can be considered the energy factories of this type of cell.
Mitochondria are able to synthesize ATP (the energy coin of the cell) by a process called cellular respiration.
The mitochondrial matrix is a fluid inside the mitochondria which is required to create a proton gradient during cellular respiration.

Answer:
Osmosis is the process cells use to move water molecules in and out of the cell through the cell membrane. When cells are put in different environments they will try to maintain an equilibrium with the water concentration outside the cell. Through osmosis the cell will lose or gain water molecules to become equal to the concentration in their environment.
