Answer:
lithosphere
Explanation:
Lithosphere is the Earth's layers has the same chemical composition as the mesosphere. The lithosphere has a rigid look and is locateed in the outer section of the Earth. It also consists of the Earth's crust and mantle.
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:A). genome chromosome DNA molecule gene
Explanation: A genome is the totality of the DNA or genes that make up an organism. A genome involves the total number of genes present in all the DNAs of all the chromosomes in an organism. An organism has many chromosomes, for instance humans have 46 chromosomes. These chromosomes are made up of DNA molecules. Chromosomes are DNA molecules arranged in a threadlike manner. Chromosomes contains all the genetic information upon which an organism is built. A DNA molecule is made up of coding and noncoding segments. The segments of the DNA that codes for a particular protein or RNA is called a gene.
Absorb and distribute materials.
Explanation: Life involves both material intake and excretion of unwanted used material from the body of an organism.
Answer:
Total Pieces Food Percentage Simulated Number of Birds
of Food Eaten in Flock for 2nd Generation
Flock X 57 19% 6
Flock Y 153 51% 15
Flock Z 90 30% 9
<u>Calculations. </u>
Food percentage:
Flock X = 57/300 * 100% = 19%
Flock Y = 153/300 * 100% = 51%
Flock Z = 90/300 * 100% = 30%
Simulated Number of Birds in Flock for 2nd Generation
Flock X = 19% * 30 = 6
Flock Y = 51% * 30 = 15
Flock Z = 30% * 30 = 9
