Answer:
The rocks may have different textures
Explanation:
If we have to igneous rocks, and they have the same minerals, that doesn't necessarily means that they will have the same name, thus being classified as the same rock. The reason for this is that the two igneous rocks may have a different texture. One of the rocks may have a foliated, while the other may have porphyritic, giving them different appearance despite the same minerals being in both of them. The reason why two igneous rocks with the same minerlas may appear different, is the process in which they have been formed, the quickness of the cooling, the temperature that they were exposed to, and the pressure they were exposed to.

Answer & explanation:
Primary succession occurs in environments that did not have biological communities in place and present unfavorable conditions for the establishment of life. Examples of these sites are rocks, dunes and newly solidified lava pits.
The pioneer organisms in primary succession are mainly producers and some decomposers.
In <u>dune</u> <u>environments</u>, for example, there are grasses, whose seeds are wind-borne and able to withstand excessive heat, water scarcity and unstable soil, and their roots are firm, preventing these plants from being harmed by the wind.
Sites with <u>rocky</u> <u>surfaces</u> can be colonized by photosynthetic bacteria, fungi or some species of algae. These organisms release substances that alter the substrate, allowing the installation of new species over time.
Answer: Approximately 1 in 70 individuals carry an mutated allele
Answer:
The cell structures which can be found in every cell are
DNA
Cytoplasm
The Cell Membrane
Ribosomes
Explanation:
The cell structures which are common to every cell whether prokaryotic or eukaryotic are
Deoxyribonucleic acid (DNA): DNA can be referred as the basic hereditary material for all organisms. In prokaryotes, DNA is not membrane bound whereas in eukaryotes the nucleus is membrane bound.
The Cell Membrane: The cell membrane comprises of phospholipid bi layers and other proteins. Cell membrane seperates the cell from the outer environment. It also acts as a barrier for imorting and exporting of materials inside and outside of cell.
Ribosomes: Ribosomes can easily be described as the protein synthesis factory.
Cytoplasm: The fluid material present inside the cell membrane which comprises of all the organelles.
