Answer:
silicon dioxide is the correct answer.
Explanation:
Diatoms are the unicellular algae, found in waterways, soil, and ocean.
diatoms cell walls are made up of silica dioxide which is called frustule because the cell wall is composed of silicon dioxide it makes the cell wall diatoms transparent, which helps them to produce more foods.
As the diatoms cell wall is composed of silica it is used as a silica source, to treat constipation and cholesterol level and also to improve the health by removing the dead cells.
O Glucagon was secreted by his pancreas before he ate the cookies because his blood glucose was low. Insulin
was secreted after he ate the cookies because his blood glucose was high.
O Insulin was secreted by his pancreas before he ate the cookies because his blood glucose was low. Glucagon
was secreted after he ate the cookies because his blood glucose was high.
O Glucagon was secreted by his pancreas before he ate the cookies because his blood glucose was low. After he
ate, insulin from the cookies increased his blood sugar levels.
O Insulin was secreted by his pancreas before he ate the cookies because his blood glucose was low. After he ate,
glucagon from the cookies increased his blood sugar levels.
During process of digestion which takes place in digestive tract statement which describes role of glucagon and insulin is glucagon was secreted by pancreas before he ate the cookies because his blood glucose was low. Insulin was secreted after he ate cookies because his blood glucose was high.
It consists of the gastrointestinal tract along with the accessory organs which are present in digestion process . It involves the breakdown of complex food into smaller components which can be easily assimilated and absorbed by the body.
The digestion process has 3 phases: cephalic phase , gastric phase and intestinal phase.Cephalic phase begins with secretion of gastric juices from gastric glands in response to sight and smell of food.It involves chewing and chemical breakdown of food by the action of digestive enzymes ,saliva in the mouth contain enzymes like lipase and amylase which are secreted by the salivary and serous glands present on the tongue.

Answer: Option A) Glucagon was secreted by his pancreas before he ate the cookies because blood glucose was low. Insulin was secreted after he ate the cookies because his blood glucose was high.
Explanation:When Kai was hungry and his blood glucose level was decreasing, glucagon is the hormone which was secreted by the islets of pancreas to increase the blood sugar levels in his body. Glucagon forces the liver to release the stored glucose in it, which increases the blood glucose level in the body. When Kai ate the sugar cookies there was enough of blood glucose available for his body, also it exceeded the requirement and went high. Insulin was then secreted to control this excess glucose from the islets of pancreas. As it helps the body cells to absorb the glucose and lowers the amount of glucose in the blood. It makes the cell available with the glucose to produce energy and perform their activities.
In short, glucagon and insulin both are secreted by the same organ which is islets of pancreas. But they differ in their function, glucagon increases the blood glucose when the body needs it, whereas insulin helps to absorb the excessive glucose and stores that in the body. Both are the hormones which help in regulating the body glucose levels.

Answer:
C I think
Explanation:
1. A chromosome contains one long DNA molecule.
DNA or deoxyribonucleic acid is a fundamental and essential macromolecule that is built from the chain of nucleotides. A nucleotide consists of one of four nitrogen-containing nucleobases (cytosine [C], guanine [G], adenine [A] or thymine [T]), a sugar called deoxyribose, and a phosphate group. DNA carries the genetic instructions used in the growth, development, functioning and reproduction of all known living organisms. It is organized (packed) into structures-chromosomes and during cell division, these chromosomes are duplicated in the process of DNA replication. The process of replication provides each cell with its own complete set of chromosomes.
2. Each gene in this molecule gives the instructions for making a PROTEIN.
The genetic information in a genome is held within genes. Genes are a sequence of DNA that codes for a molecule that has a function, and usually, it is a protein. During gene expression, the DNA is first copied into RNA in a process called transcription. Then, synthesized RNA can be directly functional or be the template for a protein that performs a function. Synthesis of protein from RNA is a process called translation.
3. Both chromosomes in a pair of HOMOLOGOUS chromosomes have the same GENE, but the two chromosomes may have different ALLELES.
Homologous chromosomes are a set of one maternal and one paternal chromosome. Those chromosomes pair up with each other inside a cell during meiosis. Homologs have the same genes in the same loci but the alleles may be different, resulting in different phenotypes of the same genes. During the meiosis, the process of crossing over occurs when homologous chromosome pair exchange parts of DNA with one another.
4. Chromosomes that are not homologous have different GENE which gives the instructions for making different kinds of proteins.
Non-homologous chromosomes differently from homologous consist of alleles of different types of genes. Non-homologous chromosomes do not pair during meiosis and the shape of the chromosome, the length of the arms and the position of the centromere, is different among those chromosomes.
Answer:
Chitin
Explanation:
Chitin is a natural biopolymer that is made of the N-acetylglucosamine, modified glucose.
Chitin is an important polymer mainly for the fungi and the arthropod insects as it is present in the cell wall of the fungi and the exoskeleton of the insects.
The chitin provides a protective function to this organism that the digestive enzymes cannot degrade this chitin but only the symbiotic bacteria can digest eat therefore they are sometimes avoided to be eaten.
Thus, chitin is the correct answer.
