Black holes are inviable because they don't reflect light? true or false

Answers

Answer 1

The gravity of a black hole is so strong that not even light can escape. Even if a bright star is shining right next to a black hole, you cannot see the black hole. Instead of reflecting the light as other objects do, the black hole just swallows the starlight forever.

The immune response consists of different components playing their role for a common goal: to rid the body of a pathogen. Create an analogy that helps explain the roles of the responses of the immune system and describe the relationship between the responses.

Answers

Answer:

In a primary immune response, naive B cells are stimulated by antigen, become activated, and differentiate into antibody-secreting cells that produce antibodies specific for the eliciting antigen.

A secondary immune response is elicited when the same antigen stimulates memory B cells, leading to the production of greater quantities of specific antibodies that are produced in the primary response

Earth is the only planet that is known to support life. Almost two-thirds of Earth's surface is covered with water. It has a rocky terrain consisting of deep valleys and high mountains. Earth is neither too far nor too near to the Sun. This ensures that there is enough sunlight to maintain moderate temperatures on Earth. Which three factors would be most important for a body in the Solar System outside of Earth to support life?

Answers

Answer:

My guess would be an energy source, water, and an atmosphere.

how would the solar eclipse be different if the moon was moved AWAY from the earth?​

Answers

Answer:

The Sun is completely blocked in a solar eclipse because the Moon passes between Earth and the Sun. Even though the Moon is much smaller than the Sun, because it is just the right distance away from Earth, the Moon can fully blocks the Sun’s light from Earth’s perspective. Sometimes the Moon is far enough away that it doesn't create a total solar eclipse. However, once the Moon's growing orbit takes it approximately 14,600 miles (23,500 km) farther away from Earth, it will always be too far away to completely cover the Sun. That won't happen for a long time though.

1. What is the gradual change in populations over time?

2. What is the idea that species originate in small gradual steps over time?

Answers

1. Gradualism

2. evolution

Answer:1.Gradualism is an evolutionary model that refers to the tiny variations in an organism or in society that happen over time to make a better fit for animals and humans in their environment. These variations allow them to survive and thrive, resulting in a slow and consistent process of change in the whole population.

2.Phyletic gradualism is a model of evolution which theorizes that most speciation is slow, uniform and gradual. When evolution occurs in this mode, it is usually by the steady transformation of a whole species into a new one (through a process called anagenesis).

Which of the following is not an appropriate unit for momentum?

A. g • cm/min

B. g • m/S

C. km • m/S

D. kg • m/hr ​

Answers

Answer:

Option C us correct.

km • m/S

Explanation:

This is because momentum is result of mass and velocity of an object. Momentum is a vector quantity that is it has magnitude and it's direction is in form of three dimensional.

From the option C, kilometer there is not a unit for mass or velocity it it is a unit for distance, therefore it is incorrect.

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.

Answers

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.

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

Answers

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.

List the three parts of the cell cycle.

Answers

Answer:

The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.

What are some negative impacts of having this life cycle that might have contributed to a decline in the dragonfly population?

Answers

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.
