The digestive organs are an example of an organ system in biology, where different organs work together to carry out a similar function.
The digestive organs are an example of an organ system in biology. An organ system is a group of organs that work together to perform a specific function. In the case of the digestive system, it includes organs such as the mouth, esophagus, stomach, small intestine, large intestine, and liver.
Each organ in the digestive system has a specific role in the overall process of digestion. For example, the mouth is responsible for chewing and starting the breakdown of food, while the stomach performs the chemical digestion of proteins. The small intestine is where most of the nutrient absorption takes place, and the large intestine is involved in reabsorbing water and forming feces.
All of these organs work together in a coordinated manner to ensure that food is properly digested and nutrients are absorbed. This is an essential process for obtaining energy and nutrients from food.

a cavity filled with fluid
layers of tissue
an inner lining of tissue
Option B, a cavity filled with fluid, is the right answer.
A coelom is a fluid-filled mass decay in bilaterally symmetrical mammals that is absolutely filled with derivatives of mesoderm. In simple terms, it is the main body cavity in many animals and is found inside the body to encompass and hold the digestive expanse and different organs. In matured creatures, it is marked with mesothelium and in other mammals like molluscs endures undifferentiated.
3:1 is correct, had this question earlier
B. primary consumer
C. secondary consumer
D. tertiary consumer
Answer;
C. secondary consumer
Explanation;
-Secondary consumers are largely comprised of carnivores that feed on the primary consumers or herbivores
-A ladybug is a secondary consumer. It eats plants and small insects that destroy plants. The small insects that it eats include aphids, which makes ladybugs good for the garden. Ladybugs, in turn, are eaten by other animals such as frogs.
A. a five carbon sugar, a nitrogenous base, and a phosphate group
B. a five carbon sugar, an amino acid, and a carboxyl group
a polysaccharide, an amino acid, and a phosphate group
C.
D.
a polysaccharide, a nitrogenous base, and a carboxyl group
DNA (deoxyribonucleic acid) is a molecule that contains the genetic instructions necessary for the growth, development, functioning, and reproduction of all living organisms. It is composed of smaller units called nucleotides, which are the basic building blocks of DNA.
The correct option is A .
The backbone of DNA is made up of a sugar-phosphate chain. The sugar component in DNA nucleotides is deoxyribose, which is a five-carbon sugar molecule. Deoxyribose is a key structural element in forming the backbone of the DNA strand. Each nucleotide contains one of four nitrogenous bases: adenine (A), thymine (T), cytosine (C), or guanine (G). These nitrogenous bases are the "letters" of the genetic code and pair with each other in specific ways (A with T and C with G) to form the rungs of the DNA double helix.
Single nucleotide of DNA always contains a five-carbon sugar (deoxyribose), a nitrogenous base (adenine, thymine, cytosine, or guanine), and a phosphate group. These components come together to form the fundamental units of the DNA molecule, allowing it to carry and transmit genetic information.
Hence , A is the correct option
