The word transcribe means 'to write out' and the word translate means 'to express in a different language'. Review the meanings of transcription and translation in protein synthesis. How do the technical meanings of these words relate to meanings of the words in ordinary language.
The word transcribe means 'to pass the code from DNA to RNA', whereas the word translate means 'change from mRNA to protein', which is a different language.
What is the genetic code?The genetic code is a series of instructions that indicate how to synthesize proteins from a given gene sequence.
During transcription, the DNA gene sequence is transcribed into a messenger RNA (mRNA).
During translation, triplets of nucleotides or codons in mRNA determine specific amino acids in the growing protein sequence.
In conclusion, the word transcribe means 'to pass the code from DNA to RNA', whereas the word translate means 'change from mRNA to protein', which is a different language.

Which of the following would explain why the total fertility rate is 3.8 five years later?
2
O A governmental policy to ensure replacement-level fertility remains constant even though there is no change in death rate.
Females are being given fewer educational opportunities so there is a reluctance to have children.
Couples are able to settle down at younger ages and quality of life has improved in the nation.
O The birth rate is determined to be 28 births for every 1,000 individuals five years later.
Option D seems to provide the most information about the total fertility rate, which is 3.8 five years later.
Why does fertility decline over time?A variety of factors contribute to the decline in fertility rates. One of the factors is primarily due to job changes, reproductive health issues, and other factors.

A heron, a large wading bird, is hunting in a pond that contains three types of prey: fish, frogs, and snakes. All three types of prey are abundant and provide the same amount of energy to the heron. The heron has the highest handling time capturing fish, an intermediate handling time capturing snakes, and the lowest handling time capturing frogs. What prey item would foraging theory predict that the heron should catch most frequently
The preferred prey item would be frogs.
What is optimal foraging theory?
It is a theory in ecology that proposes that predating animals that get the most energy from minimal efforts are favored by natural selection.
In order words, selection forces prefer investing minimum energy in order to extract maximally available energy.
In this case, the heron needs to use the lowest time to harvest the maximum energy possible. Since all the preys offer the same amount of energy, the one that requires the lowest time would be preferable for the heron.
In other words, frogs would be the most preferable prey.

A hypertonic solution has:
Fewer water molecules outside the cell than are inside the cell
More water molecules outside the cell than are inside the cell
The same number of water molecules inside and outside of the cell
No water inside or outside of the cell
A hypertonic solution has:
Fewer water molecules outside the cell than are inside the cell. Thus, option "A" is correct.
What is hypertonic solution?The cell is in a hypertonic solution because it lost water through osmosis and shrunk.A hypertonic solution contains more solute molecules compared to solvent molecules while the hypotonic solution has more solvent molecules than solute molecules.When a plant cell is placed in a hypertonic solution it loses water through osmosis and shrinks.An animal cell placed in a hypotonic solution absorbs water through osmosis, increases in size and then bursts. Plant cell, on the other hand, does not burst when placed in a hypotonic solution as it contains a cellulose cell wall.Thus, option "A" is correct.
