The hyoid bone is the attachment site for some tongue muscles. It is also called the tongue bone or the lingual bone. It functions as an anchoring structure of the tongue. It is located at the end part of the tongue, front of the neck.
1. What is the relationship between chromosomes and DNA? The chromosome is a molecule formed by a chain of DNA associated with proteins. Together, they form a group of molecules directly responsible for heredity.
2. What is heredity? It is the biological process where the genes present in a DNA are transmitted by parents to their children, through the division of gametes. These genes carry the codes that form the genotypic and phenotypic characteristics, which allows a similarity between parents and children to occur.
3. What is the role of proteins associated with the DNA molecule that makes up the gene? Proteins are responsible for keeping the DNA line tightly compressed, maintaining the chromosome structure. In addition, they control the activities of the genes present in this DNA molecule, being essential in maintaining heredity.
4. How do chromosomes participate in gene transmission? As mentioned above, genes are part of DNA and DNA is the molecule that makes up chromosomes, in this case, chromosomes are molecules loaded with genes. In the human body, cells have 46 pairs of chromosomes, with the exception of gametes that have half that number. During the reproductive process, the gametes (reproductive cells) divide and produce a new being. The mother's gametes unite with the father's gametes to form a new being. Each gamete has 23 chromosomes, which contain the genes responsible for transmitting the characteristics.
<span>Lipids have long been used as lamp oil and along with candles were the main fuel for pre-industrial light sources. Whale oil was one of the main fuels harvested and fueled the 19th century whaling industry leading to widespread endangerment of various species. This practice is now outlawed except in a number of countries which mostly hunt whales for cultural purposes.</span>
Answer:
c. Carbon Dioxide
Explanation:
The rate of respiration is determined by the presence of concentration of carbondioxide gas in the blood because in the process of respiration, energy in the form of adenine tri phosphate (ATP) and carbondioxide gas are produced. This ATP is required for performing different activities while carbondioxide gas is a waste product which must be removed from the blood through breathing. If carbondioxide gas is produced quickly so the rate of respiration is also increased in order to remove the gas from the blood.
Answer:
The most appropriate answer would be a stem cell.
Stem cells are the undifferentiated cells which have the capability to divide to give rise to more number of the same type of cell.
In addition, these cells have a capability to develop in a particular cell type or specialized cell by the process of cell differentiation.
For example, the embryonic stem is undifferentiated pluripotent cells which are capable of giving rise to almost all types of cells of the body.
