Ans.
Protein synthesis involves two stages, named as transcription and translation. During transcription, information present in DNA molecule is used to make mRNA molecule, while translation involves formation of polypeptide chain or protein by using information present in mRNA in the form of codons.
Prokaryotic organisms lake true nuclei, hence in these organisms both transcription and translation take place in cytosol. In eukaryotic organisms, transcription takes place in nucleus, while translation takes place in ribosomes, present in the cytosol.
Answer:
Alfred Wegener
Explanation:
In 1912 Alfred Wegener (1880-1930) noticed the same thing and proposed that the continents were once compressed into a single protocontinent which he called Pangaea (meaning "all lands"), and over time they have drifted apart into their current distribution.
Answer: (A) Genetic changes can be designed to make cows yield more milk.
Explanation: Milk yield per cow has more than doubled in the previous 40 years and many cows now produce more than 20,000 kg of milk per lactation due to genetic changes. This shows that genetic changes to make cows yield more milk has already occurred.
The best argument in favor of the genetic research conducted by the Animal Functional Genomics Laboratory at Mississippi State University is that genetic modifications can enhance productivity in farm animals, like increasing a cow’s milk yield.
The idea that can BEST be used to argue in favor of the genetic research conducted by the Animal Functional Genomics Laboratory at Mississippi State University involves the possibility of genetically designing changes in commercially useful farm animals to increase productivity. For instance, a genetic modification could be designed in cows to increase their milk yield (A). This has the potential to benefit the agricultural sector immensely, supporting an economic boost and possibly aiding in addressing world hunger issues with increased food production.
It's important to understand that this approach is not about creating entirely new species (B), controlling populations (C), or modifying group behavior (D). The central focus of this research is primarily on boosting productivity and efficiency in the agricultural industry.

the answer to your scientifical question is D
Answer:
During meiosis 1, the parent cell with double the normal amount of chromosomes, splits into two diploid cells (have enough chromosomes to survive). During meiosis 2, the two diploid cells each split into two haploid cells (have half the amount of chromosomes to survive). Meiosis ends with four haploid cells.
Both Meiosis 1 and 2 have the same phases: Prophase, Metaphase, Anaphase and Telophase. One difference is that Meiosis 1 starts with a diploid cell and Meiosis 2 starts with 2 haploid cells, each with a homologous pair. ... Since there are no homologous pairs (only chromatids), recombination can not occur
