‘ an enzyme is a biological catalyst that enables chemical reactions to take place. They speed up the amount of time needed for an reaction to take place. Enzymes of photosynthesis capture energy from the sun to build a larger molecule. I’m sorry I don’t know the last part.
Answer:
4 is gravitational force
Option B
Explanation:
This is a force diagram of a block on an inclined plane.
The force component is what makes up weight in the diagram. Weight is given as mass multiplied by the gravity.
Gravitational force acts downward and it is the force of attraction between all objects and the earth. It is directly proportional to mass.
Force 1 and 2 are both shear forces that acts parallel to the face of the incline. They are mostly expressed as frictional forces.
The right answer is 28 years.
The half-life, or period of a radioactive isotope, is the time required for half of the nuclei of this isotope initially present to decay naturally.
One gram of pure 90 strontium has a radioactivity of 5.11 TBq. Its beta radiation is not penetrating, which makes it difficult to measure when it is in the soil or a matrix. It is very harmful when the particle is inhaled or ingested.
What reaction? Can you show the whole problem?
Answer:
Homeostasis
Explanation:
Living systems will always try to maintain homeostasis: a steady state of all internal and external conditions.
This includes body temperature and fluid balance.
Shivering and getting goosebumps are attempts the body makes to warm itself up, which means it is trying to maintain homeostasis.
