Answer:
D) An original parent DNA strand and one newly synthesized DNA strand comprising a new DNA molecule.
Explanation:
- Semi-conservative replication refers to two strands of DNA unzip, and a new strand is assembled onto each 'conserved' strand.
- The replicated double helix consists of one old strand and one newly synthesised strand.
- It describes the structure of DNA, a twisted helix of two strands with bases joining the strands.
Answer:
The structure of proteins is complex and unique, and only specific molecules can interact with their surface features. The natural shape of each protein is termed the native state. When proteins are exposed to heat, acid, or alcohol, their shape is disrupted and they become nonfunctional or denatured.
Explanation:
Physical agents such as heat, and chemicals such as alcohol and acids cause protein denaturation, that is, a loss of the spatial conformation and structure of the proteins and with this their functionality. Depending on the intensity of the event there may be total loss of function. The three-dimensional structure of a protein is basic for the protein to perform its function correctly.
Answer:
Humans rely heavily on pollinator bees to sustain food production globally. But for decades, the insects’ population has declined, in part because of pesticide use. If the die-off continues, it will have huge economic and public health consequences for people. William Brangham reports on groups that are working on innovative ways to save the world’s jeopardized bee population — or supplement it.
Explanation:
Diffusion is the movement of a substance from an area of high concentration to an area of low concentration. Diffusion happens in liquids and gases because their particles move randomly from place to place. Diffusion is an important process for living things; it is how substances move in and out of cells
