Answer:
B
Explanation:
Both of the original DNA strands act as templates during replication. This option is correct.
I'm not sure if I will answer the question you asked, as I many have interpreted it incorrectly. In natural selection, there must be variance in the gene pool, the total frequency of alleles in a population. Now, one of the organisms may have a gene that somehow helps them survive from the selective force much better compared to the others. If this does happen, over time the gene pool will narrow down to become just the genes of that organism that survived better in the first place because the rest would be taken care of by the selective force. So, the alleles and trait come from the first organisms that had the advantage over the others of its species.
Answer:
1.ans Phylogenetic Trees
Scientists use a tool called a phylogenetic tree to show the evolutionary pathways and connections among organisms. A phylogenetic tree is a diagram used to reflect evolutionary relationships among organisms or groups of organisms.
2.ans Binomial Nomenclature Rules
The entire two-part name must be written in italics (or underlined when handwritten). The genus name is always written first. The genus name must be capitalized. The specific epithet is never capitalized
3.ans Dichotomous Key
A dichotomous key is a tool created by scientists to help scientists and laypeople identify objects and organisms. Typically, a dichotomous key for identifying a particular type of object consists of a specific series of questions.
Answer: this is because bacteria that encounter such an environment UNDERGO DEATH AS A RESULT OF WATER LOSS FROM THE CELL.
Option C.
Explanation: Water is a great medium of growth for bacteria. Several experiments have been carried out to support this statement. Also, it is a means by which the bacterium is transmitted from "a site" to another.
Answer:
Nucleic Acids are precursor for Proteins.
Explanation:
Proteins are formed( protein units called amino acids) by the decoding of specific nucleic acids to give specific Proteins.
No nucleic acids don't provide energy, these are building block of genetic material (DNA). While Proteins provide energy.
No proteins don't carry genetic information.
Yes structure of protein is determined by nucleic acids because each nucleic acids code fir specific unit of amino acid which join to form protein.
No subunits of nucleic acids are nucleotides where as subunits of Proteins are called amino acids.
Please mark it branliest if the answer is little bit satisfying.
