Answer:
B
Explanation:
Carbon is a versatile element and is found in many different chemical compounds, including those found in space. Carbon is versatile because it can form single, double, and triple bonds. It can also form chains, branched chains, and rings when connected to other carbon atoms.
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.

Answer:
Mutualism
Explanation:
Organisms of same or different species tend to interact in their natural environment. They form relationships that benefits or harms them. The relationship between two organisms is referred to as SYMBIOSIS. A type of symbiotic relationship is one in which both organisms involved benefits from the relationship. This kind of symbiotic relationship is called MUTUALISM.
This mutualistic relationship is the case here, where both the bullhorn acacia tree and acacia ants provide services that benefits both organisms. The acacia tree houses the acacia ants, providing them with shelter and food in form of highly nutritious nectar and in return the acacia ants protect the tree by helping drive away predators or herbivores.
