Answer:
B, C, & D
Explanation:
Just like any other organism, bacteria too also need to survive in their environment. When the environment become unfavorable for growth and development, they shift from a vegetative state to a dormant state. They do this through formation of endospores that are highly resistant to extreme stress. This is especially significant for bacteria that have no motility. Bacteria that have flagella can move into a new environment.
Answer:
D) How do living things get energy?
G) How are living things related?
F) Where do living things make their home?
Explanation:
Different types of organisms are present on this Earth which interact with both abiotic and biotic factors and influence the nature of the environment. So there is a need to study the living organisms in which the first thing is to arrange the living organism by a process called classification.
The questions that are necessary to classify the organisms include related to the mode of energy or nutrition, the relation between various species at the morphological and molecular level, the habitat. The relationship between the organism is a very important aspect as it makes the classification easily according to their similarities and dissimilarities.
Thus, the selected options are the correct answer.
Answer:
Prokaryotes have RHO dependent and RHO independent transcription termination; Eukaryotes have the poly A signal and downstream termination sequence transcription termination.
Explanation:
Transcription is the process by which mRNA is synthesized from DNA by the enzyme RNA polymerase. The process of transcription is keep going until some termination signal/mechanism stops it. There are various differences of transcription in prokaryotes and eukaryotes like types of RNA polymerases, nitrogenous bases utilized and the mechanism of transcription termination.
Prokaryotic termination may be dependent on RHO proteins or not.
- In RHO dependent pathway the RHO factor (protein) slide towards the RNA polymerase along the DNA and dissociate it from DNA.
- In RHO independent pathway a stem loop is formed by mRNA from a sequence which pasues the polymerase temporarily and consequently causes dissociation of RNA polymerase with help of poly-uracil sequence.
Eukaryotic termination may occur through poly A signal and downstream termination sequence;
- Poly A tail is added mRNA for its protection. It prevent the mRNA degradation.
- The polymerases pauses on the termination signal and ultimately dissociates from DNA.
Best Answer: Carbohydrates is a source of energy to keep the body moving and doing things. When the body not intake much carbohydrates all of the body will get weaken and won't do things for you.
