Which chemical is LEAST persistent in
the environment?
A. Radon
B. Agent Orange
C. PCBs
D. DDT
Answer:
D. DDT
Explanation:
DDT is highly persistent in the environment means that it break down very slowly in the environment. The half-life for DDT is from 2 to 15 years. Half-life is the time needed for the degradation of half of the compound. Persistent bio-accumulative toxic substances (PBTs) are chemicals that break down slowly in the environment and its accumulation in living organisms are toxic. Some PBTs are dispersed through air currents while some uses other environmental pathways, resulting in contamination of regions far from their points of origin.

"A large population of Rhinoceroses, in a wide variety of skin colors was almost entirely wiped out by a severe drought. The few that remained are all gray, and are slowly building the population back up. What is this type of event called?"
A. Genetic drift
B. Interspecific competition
C. Intraspecific competition
D. Population bottleneck
Answer:
D.
Explanation: A population bottleneck is an event that drastically reduces the size of a population. The bottleneck may be caused by various events, such as an environmental disaster, the hunting of a species to the point of extinction, or habitat destruction that results in the deaths of organisms.
The best answer on the type of event described in the questions is ( D ) : Population bottleneck
Population bottleneck is caused by the drastic reduction in the population of a population ( made up of varying species ) due to natural events such Fire or flood. population bottleneck can also be caused by man made activities such as indiscriminate hunting of animals or organisms.Genetic drift is the randomness in the gene variants of a populationInterspecific competition is the type of competition that occurs between animals of different species. this could be caused by the quest for territory, food or habitatIntraspecific competition is the same as interspecific but it occurs within animals of same specie.hence the type of event whereby the remaining gray Rhinoceroses are slowly building the population back is called Population bottleneck.

___ is the process of recording the base sequence from DNA into mRNA, which takes place in the ___. ___ is the process of assembling a protein from an mRNA transcript, which takes place in the ___.
Answer:
- Transcription, nucleus
- Translation, cytoplasm (ribosome)
Explanation:
Two major processes are involved in the expression of a gene in living organisms and they are: transcription and translation. Transcription is the process whereby mRNA transcript is synthesized from a DNA template. In the process of transcription which occurs in the NUCLEUS, the base sequence from DNA is recorded into the mRNA.
On the other hand, translation is the process whereby the mRNA transcript is used to synthesize an amino acid sequence. In other words, translation involves the process of assembling a protein from an mRNA transcript in an organelle called RIBOSOME located in the cytoplasm.
