The given statement-Logistic growth curves are density-dependent is True.
Logistic growth curves describe population growth that takes into account density-dependent factors, such as competition for resources and predation.
The logistic growth model assumes that as a population grows, it will eventually reach a point where resources become limited, and the growth rate slows down.
This is known as the carrying capacity of the environment, which is the maximum population size that can be supported by the available resources. Thus, the growth rate of the population becomes dependent on the population size or density. Hence, the statement is True.

The correct answer is true.
The density dependent factors are those factors, which is affect the size of the population.
The logistic growth curve shows a a lag phase, a log phase and a stationary phase. In the lag phase, the growth of the organism is minimal, here it prepare for the growth, in log phase, the population growth is exponential. As the resources in a particular area is limited and carrying capacity is also limited, after a certain population density, the growth become stationary, which means mortality becomes equal to the birth rate. As the logistic curve is affected by the density of the population, it would be density dependent.
P.S.- if the resources are not limited, the population continuous to grow exponentially, and would represent exponential growth curve.

Answer:
DNA
Explanation:
DNA is directly related to the physical and physiological characteristics of our body and other living beings, in addition to being the main molecule responsible for heredity. In eukaryotic organisms, the DNA molecule is found in the cell nucleus and in organelles called mitochondria. In prokaryotic organisms, on the other hand, this material is dispersed in the cell's cytoplasm.
DNA, like RNA, is a nucleic acid, a structure basically formed by the nucleotide.
DNA in the nucleus of a cell contains the genetic instructions for traits that are passed on to the next generation. They are found in segments of DNA known as genes and are copied and passed on during reproduction.
The hereditary material in the nucleus of a cell that is responsible for passing traits to the next generation is known as DNA (Deoxyribonucleic Acid).
DNA is a long molecule that contains our unique genetic code and holds the instructions for building the proteins that our bodies need to function. This information is located in specific segments of the DNA molecule called genes. Each gene provides a different set of instructions, for example, instructions for eye color, hair color, height, etc.
When reproduction occurs, these genes are copied and passed on from parents to their offspring, ensuring the continuity of traits from one generation to the next. Changes or mutations in these genes can lead to varied traits among individuals, which contributes to evolutionary diversity within species.
