My guess would be an energy source, water, and an atmosphere.
Explanation:
Whatever lives there is going to need energy and water to survive. The atmospheric layer will protect the planet like ours protects Earth. Hope this helps! :)
Answer:
it's going to be water, sunlight and sun

D water molecules in the leaf with more kinetic energy.
What are some negative impacts of having this life cycle that might have contributed to a decline in the dragonfly population?
Answer:
Dragonflies are important for our environment.
Explanation:
Dragon flies belongs to the ancient family of insects. They are found on every parts of the world and have been from around 300 millions years ago. There are more than 5000 different species of them found in different parts of the world. Conserving dragonflies is important as they considered as a valuable environmental indicators.
Dragon flies are found in the areas where water is available and near grasslands. Their life cycle is an example of an incomplete metamorphosis. The dragon flies lays their eggs near the water or in the water. Dragon flies spends most of the life time as a nymph in the water where they turn into an adult and leave the water. The dragon flies rely on the aquatic ecosystems all through their life. Thus dragonflies are an important indicators of the environment and water quality.
Most of the life cycle of the dragon flies depend on the availability of water and its quality. Polluting water and destroying their habitat will result in the decline of the population of the dragon flies.
Complete the chart. Thymine _____, Guanine ____.
Answer: 27, 23
Explanation: Thymine goes with Adenine and together they equal 50 so Thymine would be 27 because Adenine is 23. Same with Cytosine and Guanine. They go together and equal 50 so Guanine would be 23 because Cytosine is 27. Hope this helps!
Si se aplica a un muelle una fuerza de 30N provocamos que se alarguen 0.2m . Calcular la constante del resorte. Y que fuerza que habra que aplicarle para que se alargue 0.45m
Answer:
I. Constante de resorte, k = 150 Nm.
II. Fuerza = 67.5 Newton.
Explanation:
Dados los siguientes datos;
Fuerza, F = 30 N
Extensión, e = 0.2 m
Para encontrar la constante del resorte;
Fuerza = constante de resorte * extensión
F = ke
30 = k * 0.2
Constante de resorte, k = 30 / 0.2
Constante de resorte, k = 150 Nm
A continuación, para encontrar la fuerza para una extensión de 0,45 m;
Fuerza = 150 * 0.45
Fuerza = 67.5 Newton.
Moving a book to a lower shelf decreases potential energy.
True
False
Answer:
True
Explanation:
Moving a book so the potential energy of the system decreases is a true statement.
What is potential energy?A book's potential energy is reduced when it is moved to a lower shelf. A charge's electric potential energy is decreasing if it is traveling in the direction that it would typically go.
A charge's electric potential energy increases if it is pushed in the opposite direction from how it would ordinarily travel.
Since the potential at the Earth's surface is zero, gravity always has a tendency to draw items toward the planet's center, this causes the potential energy to be reduced.
Therefore moving the book to a lower shell change potential energy, which decreases.

Human Immunodeficiency Virus (HIV) is a virus that infects (and destroys) Helper T Cells. As a result, people who are HIV+ generally have a low number of these T Cells. How would the dramatic decrease in Helper T Cells caused by HIV affect a person’s immune response? Be specific using details from what you learned about the immune response.
Answer:
HIV invades various immune cells (e.g., CD4+ T cells and monocytes) resulting in a decline in CD4+ T cell numbers below the critical level, and loss of cell-mediated immunity − therefore, the body becomes progressively more susceptible to opportunistic infections and cancer.
HIV infects and deletes CD4+ T cells that normally coordinate the adaptive T- and B-cell response to defend against intracellular pathogens. The immune defect is immediate and profound: At the time of acute infection with an AIDS virus, typically more than half of the gut-associated CD4+ T cells are depleted, leaving a damaged immune system to contend with a life-long infection.
