Answer: The perecentage of guanine is 30%
Explanation:
According to the Chargaff's rules the DNA from any cell of all organisms should have a 1:1 ratio (base Pair Rule) of purine bases [for the DNA cytosine, thymine and for the RNA uracil] and pyrimidine bases [guanine and adenine for RNA and DNA]. The amount of guanine should be equaled to cytosine and the amount of adenine should be equaled to thymine. You can follow this rule in both strands of the DNA.

Identify all correct statements about how viroids differ from viruses.
Select all that apply.
-Unlike viruses, viroids do not encode proteins.
-Unlike viruses, the genetic material of a viroid is protein.
-Unlike viruses, viroids cause plant disease.
-Unlike viruses, viroids do not encode proteins.
Viroids are small infectious agents composed solely of RNA molecules. The correct statements about how viroids differ from viruses are:
1. Unlike viruses, viroids do not encode proteins.
3. Unlike viruses, viroids cause plant disease.
Viroids lack the protein coat typically found in viruses and do not encode proteins of their own. Viroids are known to cause diseases in plants and are not associated with animal or human diseases.
Viroids are unique infectious agents that differ from viruses in several ways. One of the key distinctions is that viroids do not encode proteins, unlike viruses. While viruses are composed of genetic material (either DNA or RNA) surrounded by a protein coat, viroids consist solely of small RNA molecules. This means that viroids cannot produce their proteins and rely on host cellular machinery for replication.
Therefore, the correct statements about how viroids differ from viruses are:
1. Unlike viruses, viroids do not encode proteins.
3. Unlike viruses, viroids cause plant disease.

What is number of ATP molecules produced per molecule of glucose when Pyruvate is used to produce NADH, ATP, and FADH2
Answer:
2 ATP molecules.
Explanation:
This question is describing KREB'S CYCLE, which is the second stage of aerobic cellular respiration that occurs in the mitochondrion. In the Kreb's cycle, also known as tricarboxylic acid cycle, pyruvic acid (product of glycolysis) is oxidized to produce NADH, FADH2, ATP and CO2 as products.
In a nutshell, per glucose molecule that begins the respiration process (glycolysis), 2 molecules of ATP are produced alongside 3 NADH and 1 FADH2 molecules in the Krebs cycle. Note that, the electron carriers (NADH and FADH2) are used in the electron transport chain.

Kelly's teacher asked the class to explain how the rough endoplasmic reticulum works with the nucleus to maintain homeostasis.
Which student's statement is BEST evaluated by the claim and why?
biology
Answer:
C
Explanation:
Because the roughly endoplamsic works with nucleus and it does so to maintain homeostasis it has to.
Jacob clarified that when issues develop synthesize proteins in the rough endoplasmic reticulum signals the nucleus can receive signals from the reticulum to control the synthesis of proteins.
What is rough endoplasmic reticulum?Because it produces proteins for the cell, the rough ER (endoplasmic reticulum) aids in the maintenance of homeostasis. The role of the rough ER is to produce proteins that are either going to be secreted or are going to other membrane-bound organelles in the endomembrane system.
The ER has a special degree of control over protein synthesis because of its close proximity to the cell nucleus.
When issues with protein synthesis and folding arise, the rough ER can quickly transmit signals to the nucleus, which affects the overall pace of protein translation.
Therefore, the nucleus can receive signals from the rough ER to control the synthesis of proteins.

1. Which statement is scientifically accurate? A. "Don't let the cold energy out of the fridge!" b. "Don't let the energy into the fridge!" Explain in terms of energy transfer.
Answer:
The accurate statement is b. "Don't let the energy into the fridge!"
Explanation:
Heat is energy. Inside a fridge there is lower heat - lower energy - than the surroundings. The spontaneous transference of energy is always from a place with higher energy (hot) to a place with lower energy (cold). So, as the frigde is cold, the heat is transferred from the surroundings to the fridge.

36. What are the functions of proteins?
37. What foods contain high amounts of protein?
38. What are the four levels of structure found in proteins?
30.Water molecules are polar because they have positive and negative ends, rather like little magnets. Most lipids are non-polar (having no charged areas) or only slightly polar, with a very few charged areas. Water mixes with hydrophilic (water-loving) compounds by sticking to their charged groups.
31.Lipids are detected using the emulsion test. This is what happens: The test substance is mixed with 2 cm 3 of ethanol. An equal volume of distilled water is added.
32.In addition to carbon, hydrogen, and oxygen atoms, all proteins contain nitrogen and sulfur atoms, and many also contain phosphorus atoms and traces of other elements. Proteins serve a variety of roles in living organisms and are often classified by these biological roles.
33.amino acids
For example, proteins are composed of monomers called amino acids. They are linked together to form a polypeptide chain, which folds into a three dimensional (3D) structure to constitute a functional protein
34.Peptide Bonds
Section 3.2Primary Structure: Amino Acids Are Linked by Peptide Bonds to Form Polypeptide Chains. Proteins are linear polymers formed by linking the α-carboxyl group of one amino acid to the α-amino group of another amino acid with a peptide bond (also called an amide bond).
35.A polypeptide is a single linear chain of many amino acids (any length), held together by amide bonds. A protein consists of one or more polypeptides (more than about 50 amino acids long). An oligopeptide consists of only a few amino acids (between two and twenty).
