Answer:DNA is antiparallel.
Explanation: DNA is a double stranded helix in which the two strands are antiparallel. Being antiparallel means that as one strand runs from 5'->3' direction, the other strand runs from 3'->5' direction. During DNA each of the two strands serves as a template for a new complementary strand. The synthesis of a new DNA strand is always in the 5'->3' direction, therefore one strand is synthesized continuously in the direction of the replication fork while the other strand is synthesized discontinuously in the direction opposite to the replication fork in short fragments called the Okazaki fragments. The strand that is synthesized continuously is called the leading strand while the strand that is synthesized discontinuously in Okazaki fragments is called the lagging strand.
A scientist designed an experiment to test the effect of temperature on bacterial growth. The independent variable in this experiment was temperature.
<h3>What is the bacterial growth?</h3>
The outcomes display that microbes have a better increase price at 20, 25 and 30°C and 30°C than at 3°C. In general, an boom in temperature will boom enzyme pastime. But if temperatures get too excessive, enzyme pastime will reduce, and the protein (the enzyme) will denature.
General, the better the temperature, the greater without problems microorganisms can develop as much as a sure point. Very excessive and coffee temperatures each impede the enzyme strategies microorganisms rely on to survive.

Answer:
Positively charged ions
Explanation:
Histones are a group of proteins with a N-terminal end of an amino acid, that binds to the DNA in the nucleus helping it to condense into Chromatin. DNA wraps around a core of proteins to initially form the NUCLEOSO ME structure, which is the basic subunit of Chromatin. Each nucleosome is made up of DNA coiled around two copies (2) of proteins- H2A, H2B, H3 and H4, to form a set of eight proteins called histone octamer.
Due to the phosphate group (PO4-) embedded in the DNA molecule, they assume a negative charge. The positively charged ions of the N(C) terminal end of histones which arise from the amino acid group they contain allows it to bind tightly to negatively charged DNA i.e. the more positively and negatively charged the histone and DNA are respectively, the tighter the binding.
Due to this property, the proteins that binds to DNA in E.coli, should possess a positive charge in similarity to histones in eukaryotes.
Cellular respiration is a process that converts glucose and other chemicals and substances into ATP (energy used by the cell). This is important because if we didn't have cellular respiration, we would not have energy to move our bodies and die off.
