Answer: peptide bonds
Explanation:
A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water.
This is a dehydration synthesis reaction (also known as a condensation reaction), and usually occurs between amino acids.
Which of the following statements is true regarding anabolism?
Choose 1 answer:
А) Energy is released during anabolic reactions.
B) In anabolism, larger molecules are made from smaller molecules.
C) Anabolism is the sum of all the chemical reactions in a cell.
D) Anabolism uses the process of hydrolysis to join molecules together.
Answer:
B) In anabolism, larger molecules are made from smaller molecules.
Explanation:
Anabolism is a metabolic process that uses up energy that is produced to build up complex and larger molecules from smaller ones. It is part of the chemical process that takes place in a cell.
For example, photosynthesis is an anabolic process, in which the cell forms larger molecules such as glucose from smaller molecules like water and carbon dioxide, with the use of solar energy.
Option B is true regarding anabolism.
Identify the structure represented in the picture . Then, identify the parts labeled A—D.
Given structure is that of a virus, which includes the viral capsid, nucleic acid, etc.
A= spike
B= Envelop
C= Nucleic acid
D= Capsid
What are Viruses?Small infectious agents known as viruses can multiply only in the living cells of other animals. They are composed of genetic material, which can be DNA or RNA, encased in a protein shell called a capsid. Some viruses also have a lipid-based outer coat.
Because they cannot perform metabolic functions on their own and require a host cell to reproduce, viruses are not considered living organisms. They spread infection to various living things including bacteria, plants, animals and people.
A virus replicates its genetic material and forms new viral particles when it infects a host cell using the host cell's machinery. This can lead to the death of the host cell and result in the spread of the virus to other cells of the host.
Therefore, given structure is that of a virus, which includes the viral capsid, nucleic acid, etc.
A= spike
B= Envelop
C= Nucleic acid
D= Capsid

How digestive enzyme affected when people having high fever? Explain.
Higher the body temperature, it would disrupt the shape of the active site of the enzyme , which will reduce its activity, or prevent it from working. The enzyme will have been denatured also the protein which can also lead to death.
Answer:
When a person has high fever, it's body temperature increases.
When the temperature is too high, enzyme molecules vibrate vigorously causing it to lost it's shapes and active sites.
Then, started to denatured and eventually, the enzyme died and no longer able to function.
Which of the following describes how damaged DNA can lead to a mutation?
A. The damaged DNA stops all protein synthesis by the cell.
B. An error occurs when the damaged DNA is repaired.
C. The segment of DNA that is damaged is transcribed into RNA.
D. The nucleotide sequence of the damaged DNA is restored
perfectly
Answer:
B.an error occurs when the damaged DNA is repairex
Explanation:
the best answer is B
The damaged DNA can lead to a mutation represent that option b. An error occurs when the damaged DNA is repaired.
Reason for damaged DNA?In the case when the DNA is damaged so it should be replicated that shows an incorrect base which should be inserted opposite the site of the damaged base in the strand i.e. complementary.
Due to this, it should become the mutation at the coming replication round.
Moreover, the double-strand DNA split might be repaired.
Hence, the option b is correct.

A biology teacher takes fish, algae, pond weed, invertebrates, and bottom muck from a local pond and establishes them in an aquarium. When the system is stable, the teacher seals it into a large, airtight glass box and leaves the box in a sunny location. After 3 months, the organisms in the aquarium appear alive and healthy. Which of the following statements about the experiment is NOT correct? For EACH one of the choices indicate if it is a correct or incorrect statement and explain why (the explanation MUST include the information covered in class)
A) During the 3 months, the biomass of plant life was greater than the biomass of animal life.
B) No energy has entered or left the glass box during the 3 months,
C) Some atoms from water molecules have become parts of organic molecules,
D) The air in the glass box contains carbon dioxide.
E) Some of the energy in the system has moved from one organism to another during the 3 months
Answer:
E
Explanation:
Some are heterotrophic and the other are autotrophic.
Some of the energy in the system has moved from one organism to another during the 3 months. Hence option E is correct.
What is aquarium?Aquarium is defined as any size tank with at least one transparent side used to house and display aquatic plants and animals. Like zoos, aquariums offer enjoyable leisure and amusement activities that also serve as locations for scientific research, education, animal care, and conservation.
Your fish may die if there are any significant temperature variations in their tank. Do not place your tank close to cooling vents or in a location that gets a lot of sunlight. A steady water temperature of 72°F to 82°F is required for freshwater fish, while 75°F to 80°F is ideal for saltwater fish.
Thus, some of the energy in the system has moved from one organism to another during the 3 months. Hence option E is correct.
