CaHeK987 [17]3 years ago
8 0

Answer:

Archaea and eukaryotes are very closely related than bacteria and eukaryotes. because both archaea and bacteria responsible for the formation of more complex cells

Explanation:

  • It has been believed for many years that archaea and eukaryotic cells are genetically related to a developmental process that involves the production of eukaryotic cells by archaea development.
  • At the same time, scientists believe that archaea have more to do with eukaryotic cells than bacteria.
  • This is because research shows that bacteria are also closely related to eukaryotic cells, meaning that along with archaea, bacteria are part of the evolutionary process that makes up these cells.

What is the difference between an exchange pool and a reservoir? What role do these areas play in the water cycle?
goldfiish [28.3K]

Answer:

EXCHANGE POOL is a part of the cycle that holds water for a short period of time. 

RESERVOIR POOL is a part of the cycle that holds water for a long period of time. 

So, the main difference is the period of time each one holds water during the water cycle. 

Explanation:

Water is recycled during the water cycle. Chemical elements and water that are important for an ecosystem and the animals living in it are CONSTANTLY being recycled.  For instance, chemicals might travel from organisms to the atmosphere or oceans and come back to the organisms again. But, it certainly happens that water is held for many years in different parts of the cycle. For example, the atmosphere plays the role of an exchange pool because it holds the water in the shape of vapor for just a few days. The ocean is a reservoir for water since it may hold water for thousands of years. The water cycle happens on, above and below earth surface, so the water cycle is a global cycle.

The lac operon can be regulated by two distinct methods. Which of the following statements are correct?The lac operon can be act
Ad libitum [116K]

Answer:

  • The lac operon can be activated by the binding of allolactose to the repressor protein, releasing it from DNA and thereby allowing for transcription to occur.
  • In response to low glucose levels, cAMP is upregulated; the binding of cAMP to the cAMP receptor protein triggers the activation of the operon.

Explanation:

Lactose operon or lac operon  (includes lacZ, lacY and lacA genes) is found in some bacteria and the products of its genes are involved in lactose metabolism. So, this operon is active (genes are transcribed) when lactose is present and glucose is absent (or at low level). The operon is regulated by the lac repressor which acts as a lactose sensor and catabolite activator protein (CAP) which acts as a glucose sensor.

When there is lactose (in the form of allolactose) lac repressor detects it and stops being repressor. This enables transcription.

CAP detects glucose (via cAMP) and activates transcription when glucose levels are low.
