DNA is the genetic material that is passed from parents to offspring. This means that the DNA of the offspring will be a combination of the DNA of the parents. DNA is involved in the process of cell division. Cell division is the process that produces new cells, and it is essential for reproduction.
When a sperm cell fertilizes an egg cell, the DNA from the sperm cell and the egg cell combine to form a new cell. This new cell contains all of the genetic information that it needs to develop into a new organism.
The process of cell division is also important for reproduction. When a cell divides, the DNA is replicated so that each new cell has a copy of the original DNA. This allows the genetic information to be passed on to the next generation.
So, DNA is essential for reproduction because it is the genetic material that is passed from parents to offspring, and it is also involved in the process of cell division.

Hi there! ;)
DNA is a molecule that carries genetic instruction used in growth, development, and functioning and reproduction to all living organisms.
Reproduction is the process of copying of something.
If you want to match your DNA with somebody else besides your parents it is not going to match because the reproduction is not going to match. Reproduction is a process of copying of something and you get your DNA from your parents.
Hope I helped! :D
Answer:Read the excerpt from chapter 7 of Night.
We all got up. We all pulled our soaked blankets tighter around our shoulders. And we tried to take a few steps, to shuffle back and forth, in place.
Suddenly, a cry rose in the wagon, the cry of a wounded animal. Someone had just died.
Others, close to death, imitated his cry. And their cries seemed to come from beyond the grave. Soon everybody was crying. Groaning. Moaning. Cries of distress hurled into the wind and the snow.
The lament spread from wagon to wagon. It was contagious. And now hundreds of cries rose at once. The death rattle of an entire convoy with the end approaching. All boundaries had been crossed. Nobody had any strength left. And the night seemed endless.
Which sentence from the passage best supports the author’s viewpoint that the situation is hopeless?
“We all pulled our soaked blankets tighter around our shoulders.”
“The lament spread from wagon to wagon.”
“It was contagious.”
“The death rattle of an entire convoy with the end approaching.”

Answer:
The correct answer will be- the molecules move from high concentration to low concentration.
Explanation:
Diffusion represents the movement of solute particles that is ions or molecules. The movement is driven by the concentration gradient that is from the higher concentration to lower concentration.
The diffusion can be categorized into two types: simple and facilitated diffusion. In biology, diffusion plays an important role as the important solute particles move into and out of the cell through this process.
Thus, the molecules move from high concentration to low concentration is the correct answer.
During diffusion, molecules move from area of high concentration to an area of low concentration to achieve equilibrium.
During diffusion, molecules move from an area of high concentration to an area of low concentration. This happens due to the random motion of the molecules. The goal of diffusion is to achieve equilibrium, where the concentration is equal throughout the space.

Answer:Secondary consumers eat herbivores. They are at the third trophic level. In a desert ecosystem, a secondary consumer may be a snake that eats a mouse.
Explanation:
Current populations of organisms vary significantly depending on the species and ecosystem. For instance, the population of pine trees in a forest is determined by ecological factors. Total known species represent a fraction of entire biodiversity, with limitations due to resources and political will.
The current population of an organism varies greatly depending on the species and its ecology. For instance, in a forest, each pine tree is an organism and all these pine trees together make up a population. The number of individuals in this population would be dependent on various ecological factors such as availability of resources and interactions with other species.
Furthermore, it's important to note that our current knowledge of species that inhabit the planet is quite limited, and always will be, due to lack of resources and political willpower. Estimates suggest that the known eukaryote species, approximately 1.5 million, account for less than 20 percent of the total eukaryotes present on earth (around 8.7 million species, according to one estimate). For prokaryotic species, current numbers are largely speculative and scientists agree that we have only begun to catalog their diversity.

Answer:
A disease in the population of rabbits. Trapping has severely reduced the population of rabbits in an ecosystem, as shown in the bar graph. ... The grass, rabbit, snake, and hawk populations will all decrease rapidly. The grass population will decrease rapidly and the snake population will increase rapidly.
Answer:
Explanation:
The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged). Atoms have different properties based on the arrangement and number of their basic particles.
Explanation:
Issun Shingeki... Messatsu!
In short, electrons are the negative charge in Atoms.
