Isotopes are variants of a particular chemical element which differ in neutron number (neutral particle)and all isotopes of a given element have the same number of protons (positive particle) in each atom.So isotope B of the sodium will have 11 protons, 11 electrons but it may have a wide range in its number of neutrons.
Answer:
<u>D) the nucleic acid (either DNA or RNA)</u>
<u />
Explanation:
Phages, or bacteriophages are viruses that infect bacteria.They have varying shapes, and sizes, and may contain one of two kinds of nucleic acid; these are RNA and DNA.
The nucleic acids are made up of nucleotides. These are genetic storage biomolecules made up of the monomers ribonucleic acid (RNA) deoxyribonucleic acid (DNA).
1 c is the answer. <span>Energy is not created or destroyed; it can change form or can be transferred.
2d work is calculated as newton x </span>displacement so 60 x 4= 240 joules
Because water molecules are polar(partially negative and postive charge)
Decrease resource use methods might be used to decrease the rate of approach to carrying capacity by the developed world
<u>Explanation:</u>
Carrying capacity is the greatest quantity of people of a supplied species that an area's sources can support frequently without significantly spending or diminishing those resources. For communities which increase exponentially, growth begins gradually, starts a fast maturity phase and then straightens off when the carrying capacity for that species has been touched.
The proportion of the population then shifts somewhat above or below the carrying capacity. Reproductive lag time may produce the population to exceed the carrying capacity temporarily. The carrying capacity may be reduced by resource leveling and disgrace during an overshoot period or spread through technological and social changes.
