Answer:
Every particle attracts every
other particle in the universe
using a force that is directly
proportional to the product
of their masses and inversely
proportional to the square of
the distance between them. (theory)
Human beings walk on the
ground rather than floating
in the air. (law)
Human beings walk on the
ground rather than floating
in the air because of Earth's
gravitational force. (fact)
Explanation:
theory: Us humans always come with theories so that it will make it a lot easier for us to understand the whole picture. So that's why the first part is a theory because we have never seen every particle attract an other particle. but because of the modern technology we are able to make a trustworthy theory.
Fact: We know that humans walk on the ground because of the earth's gravitational force.
law: This law mathematically describes how two different bodies in the universe interact with each other.
I hope this is ok :)
12. The goal is meiosis is to reduce the number of chromosomes by half.
Some molecules are too big they cannot diffuse through the membrane, for example starch (glucose) molecules.
The endocrine
system is the system that comprises all the glands in the body, from the hypothalamus
pituitary, pineal, thymus, thyroid, parathyroid, adrenal glands, testes and
ovaries. These organ glands mentioned are just the few major glands in the
body. Moreover, take note of the hypothalamus which is responsible for many
functions such as hunger, thirst and other simple urges, that also regulates
the pituitary gland. How does your endocrine conserve body water? By
controlling and regulating your water intake and outtake, ensuring the amount
of electrolytes is efficient. Your hypothalamus is responsible for water
balance hence, it participates in one of the many functions such as regulating
the sweat glands excretion of sweat which is by the process of osmosis promoting
skin-temperature homeostasis.
