Red pandas are going extinct because of habitat destruction. They also reproduce slowly, that's why they're one of the most endangered animals.. :(
Answer:
True.
Explanation:
The water cycle does not exclusively need life to function. The water cycle consists of 3 steps in any given order:
1. Water falls to the surface.
2. Water evaporates from the surface.
3. Water condenses into clouds in the atmosphere.
Answer:
See below
Explanation:
The correct statements can be two of the following:
1) Rough Endoplasmic reticulum has ribosomes attached to it.
2) Smooth endoplasmic reticulum do not have ribosomes attached to it.
Follicle cells in your scalp assemble proteins to build new hair. This most likely involves dehydration synthesis reactions.
Dehydration synthesis forms a peptide bond between amino acids and releases a water molecule. Amino acids connected via peptide bonds form a polypeptide chain, which then chemically interact with other polypeptides in order to create a complex three-dimensional structure of the protein.
Answer:
Nitrogenous bases contain the genetic information, their amount is variable among different species, and the arrangement of these bases is also variable among different species
Explanation:
Both Watson-Crick and Pauling's DNA models considered that DNA nitrogenous bases (i.e., Adenine, Cytosine, Thymine and Guanine) contain the genetic information that determines the characteristics of living organisms. Moreover, both DNA models also considered that nitrogenous base composition varies between species, as well as the arrangement of these bases in the DNA chain also varies between species. Based on these features, Linus Pauling considered that a model where nitrogenous bases would be arranged on the outside of the DNA molecule would be easier for the DNA molecule to be replicated, transcribed, or repaired. Although incorrect, Pauling's DNA triple helix model was fundamental to develop the helical (double-stranded) structure of DNA, which was finally discovered by Watson and Crick in 1953.
