Answer:
What do they look like?
Glaciers look like solid blocks of ice.
What climate do they exist in?
Regions that have high snowfall in winter and cool temperatures in summer.
Where can you find them?
Most of the world's glacial ice is found in Antarctica and Greenland, but glaciers are found on nearly every continent, even Africa.
What do you think we can learn from glaciers?
Glaciers preserve bits of atmosphere from thousands of years ago in these tiny air bubbles, or, deeper within the core, trapped within the ice itself. This is one way scientists know that there have been several Ice Ages. Scientists are also finding that glaciers reveal clues about global warming.
(The last question is unclear to me, so I'm going to take a guess as to what you meant)
Why is sea ice so important?
Arctic sea ice keeps the polar regions cool and helps moderate global climate.
I hope this helps!! :3
Answer:
<u>Inducer</u>
<u></u>
Explanation:
Structural proteins within bacteria are encoded along with their functions. These are typically found in a block of genes called an operon. They undergo transcription together with the use of a single promoter sequence to form a polycystronic transcript- this allows for the simultaneous control and regulation of biochemical pathways. This is efficient as these pathways would either need to function together when "switched on" or will not be needed when "switched off". Repressors are proteins that effectively hinder translation by binding to DNA at the operator site, blocking the activity of RNA polymerase in transcription. However inducers are small molecules that can displace these, freeing up the operon for transcription and the activation of relevant biochemical pathways.
The mal operon includes genes which mediate the breakdown of the substrate maltose in bacterial cells. Maltose, called a malt sugar, is a carbohydrate compound made up of two glucose molecules joined by an α-(1,4) glycosidic linkage.
In the presence of maltose, the inducer binds to the activator. This then allows for the binding of RNA polymerase, which facilitates translation and th epr
Conifer tree is the tree that the leaf is slender like needle, it is evergreen tree more, material is general softer, some contain colophony , reason calls soft material again, its grows in elevation 100 ~ 1500 meters commonly, have economy and ornamental value.Conifers appeared 280 million years ago before any other trees.Conifers are believed to be the oldest trees on earth。
Definitely belongs to the fungi kingdom!
did you hear the joke about the fungus???
... I could tell you, but it'd take some time to grow on ya!
goodluck my friend, :-)
