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.
When a animal changes their body over long periods of time with mating with other species to develop different characteristics.
When it comes to questions like this, always pick the ones that say something like "saving the planet"
So, this one is... B. Recycled materials are often more expensive but they save resources such as trees or materials.
Answer:
Regarding translation the following statements is <u>false</u>: The mRNA strand is read from 3' to 5' direction during translation.
Explanation:
The <em>primary structures</em> for protein synthesis are the ribosomes, organelles composed by the <em>association of proteins with rRNA and tRNA</em>. During translation, mRNAs are read in the 5´ to 3´ direction, and tRNA transfer amino acids to build the polypeptide chain. The <em>protein is synthesized</em> from the amino terminus<em> to </em>the carboxy terminus. Each amino acid is <em>specified by a </em>codon formed by three bases in the mRNA. mARNs have a<em> </em>start and end codon that tells the ribosome where to start and stop adding amino acids. When the ribosome reaches the end codon, it means that protein synthesis is finished.
Answer:
The options are
A. Both the cell membrane and nuclear membrane are coverings.
B. Both the cell membrane and the nuclear membrane controls the cell's activities.
C. Both the cell membrane and the nuclear membrane let out waste.
D. Both the cell membrane and the nuclear membrane allow substances to enter the
cell.
The answer is A. Both the cell membrane and nuclear membrane are coverings.
Explanation:
Mike’s mom compared the cell and
nuclear membrane by saying that the nucleus is surrounded by the nuclear membrane, which is like a blanket that protects the nucleus. The cell membrane is the outer covering of the cell, much like the nuclear membrane is the covering of the nucleus.
