Answer:
B
. Knowing the climate makes it easy to predict the weather.
C
. If it is cold today, you almost certainly live in a cold climate.
D
. Weather can change quickly, but climate changes slowly.
Explanation:
If we know the climate of a particular region we can predict the weather of the next day or week of that region because climate is remain the same of a specific region. If the weather is cold it means that you live in a cold climate, similarly, if the weather is warm it means the climate of that region is warm and hot. Weather can change and has high variations whereas climate is the average atmospheric conditions of a region for a long period of time.
Answer:
the observations that chloroplasts and mitochondria resemble bacteria
Explanation:
The Endosymbiotic Theory is a theory that enables us to understand the origin of eukaryotic cells. The Endosymbiotic Theory posits that the mitochondria and chloroplast, which are organelles found in the eukaryotic cells, were once prokaryotic microbes that were first ingested by amoeba-like organisms and subsequently evolved by developing a symbiotic relationship with them. Some of the most important lines of evidence that supports this theory are: 1-chloroplasts and mitochondria resemble prokaryotic cells, i.e., they have a similar size, replicate by binary fission and there are unicellular eukaryotic protists that have filamentous temperature-sensitive proteins at their division plane (similarly to bacteria), and 2- chloroplasts and mitochondria are organelles with their own DNA and their own ribosomes (which are similar to those of bacteria).
Enzymes are (usually) specific to the substrates they bind to. Thus, each enzyme has one and only one substrate structure they can metabolize, so even substrates with similar structures cannot be broken down by an enzyme specific to one of them.
Answer:
Translation
Explanation:
Translation is the process by which mRNA is decoded and translated to produce a polypeptide sequence, otherwise known as a protein. This method of synthesizing proteins is directed by the mRNA and accomplished with the help of a ribosome, a large complex of ribosomal RNAs (rRNAs) and proteins. In translation, a cell decodes the mRNA’s genetic message and assembles the brand-new polypeptide chain. Transfer RNA, or tRNA, translates the sequence of codons on the mRNA strand. The main function of tRNA is to transfer a free amino acid from the cytoplasm to a ribosome, where it is attached to the growing polypeptide chain. tRNAs continue to add amino acids to the growing end of the polypeptide chain until they reach a stop codon on the mRNA. The ribosome then releases the completed protein into the cell.
