Answer:
In compare to eukaryotes,prokaryotes are morphologically simpler,more evolutionary primitive,less sensitive to physical environment.
Explanation:
Prokaryotes are unicellular organism which don't possess cell organelle like nucleus,mitochondria,Endoplasmic reticulum,golgi body, etc.
They are the first living organism in the primitive earth and the genetic components are located in the cytoplasm which is enclosed by cell membrane.
prokaryotes contain 3 domains that are Archaea, bacteria and eukarya.
The cytoplasm is enclosed by cell membrane.
Molecular studies have reveal that eukaryotes are evolved from prokaryotes.
Some prokaryotes bear long projection which helps them for locomotion,called as flagellum.This is present in gram positive and gram negative bacteria.
Answer:
B
Explanation:
An ionic bond is formed when an atom usually metallic, loses an electron to become positively charged and another atom usually non-metallic, gains such electron lost and becomes negatively charged..
Approximately 1,000 to 30,000 years old
The sun is the primary source of energy for living things mostly organisms like plants and ecosystems. But if you're talking about the bonds inside organic molecules, which are carbohydrates. With this, the energy from the sun gets trapped within a chemical bond and still relates to photosynthesis in plants.
Answer:
The correct answer is - Grant's research on finches on the Galapagos islands.
Explanation:
Grant's research was made on medium-sized finches on the Galapagos islands showed evolutionary processes in real-time. He showed that due to the drought there is a decrease in the number of small and soft seeds that were finches major food source.
It is known that there are different beak sizes in this finch species, the finches with larger beaks could feed on tough and large seeds and survive in such case of the drought-induced decrease in food availability. Due to this natural selection and adaption the number of larger beaks in finches is increased over the real time.
