Question 1(Multiple Choice Worth 2 points)(05.05 MC)How does the human immune system initially respond to a pathogen?

Answers

Answer 1

Immediately, the pathogen has been recognized:

Macrophages acts as the first line of defence by engulfing pathogens identified by antigens which will now present the antibody shape to a helper T cell.

The Helper T cells produce a signal to plasma and Memory B cells to yield antibodies that attach to the antigens. The cytotoxic cells that leads to cell death are activated by the helper T cells.

Antibodies helps to immobilize pathogen for macrophage to feed on.

if the pathogen comes back a 2nd time the memory cells helps in quick and efficient recovery by producing the specific B and T cells for the antigen.

Fossil fuels store energy from the sun as

Answers

Fossil fuels are simply solar energy stored in a secondary form. The original energy from the Sun is captured through photosynthesis and stored in chemical bonds as plants grow. This energy is then released millions of years later after these plants have transformed into fossil fuels.

Fuels, including fossil fuels, are energy sources. Fossil fuels are powered by solar energy, which also powers photosynthesis, which transforms carbon dioxide and water into the fundamental constituents of prehistoric plants and animals.

What Fossil fuels store energy from the sun?

Biomass, fossil fuels, as well as some renewable energies like wind and solar power, are all derived from the sun. Simple solar energy in a secondary form is what fossil fuels are.

This energy is then released millions of years later, when these plants have transformed into fossil fuels.

Therefore, Simple solar energy in a secondary form is what fossil fuels are. Through photosynthesis, the sun's initial energy is collected and stored in chemical bonds as plants develop.

Photoperiodism is one example of how a plant responds to changing seasonal conditions. Why is it important for plants to be able to respond to seasonal changes?

Answers

Answer:

It is important because plants respond to light depend, logically enough, on the plant's ability to sense light. Phototropism is a directional response that allows plants to grow towards, or in some cases away from, a source of light. Photoperiodism is the regulation of physiology or development in response to day length.

Answers

If a planet is close to the Sun, the distance it orbits around the Sun is fairly short. This distance is called an orbital path. The closer a planet travels to the Sun, the more the Sun's gravity can pull on the planet. The stronger the pull of the Sun's gravity, the faster the planet orbits.
