Objects in our solar system are in a spinning motion because THE GRAVITATIONAL PULL OF THE SUN PUSHED OBJECTS INTO A SPINNING MOTION.
The reason why the planets orbit around the sun is because the gravity of the sun keeps them in their circular paths. The gravity is a fundamental part of the universe structure. The planets revolving around the sun traveled in a circular path because they have velocities that are perpendicular to the velocity of the sun.
<u>Answer</u>: <em>Option 2</em> foreign antigens
<u>Explanation</u>:
<em>Antigens</em> are proteins that are found on the surface of a pathogen and <em>white blood cells </em>(leukocytes) are the cells of the immune system which helps fight infection and protect the body from foreign antigens.
Whenever a foreign antigen enters the body, a type of white blood cell called as the lymphocyte recognizes it and then produces antibodies against it, to generate an immune response.
So, <em>an immune response is primarily due to white blood cells recognizing foreign antigens.</em>
Answer:
Solar energy (light energy)
Explanation:
Plants absorb the energy from the sun along with water,carbon dioxide to photosynthesize and produce their own food (starch,glucose) and oxygen.
I hope this helps:)
Water wouldn’t be able to form hyrdogen
Reaction will be faster.
Rate of reaction is proportional to the number of enzymes involved in the reaction.
