400k acres have been destroyed by logging
Answer:
See the answer below
Explanation:
Homeostasis refers to the maintenance of relatively constant internal body processes. This is done in two ways
- <em>Negative feedbacks</em>
- <em>Positive feedbacks</em>
Negative feedback returns body processes back to normal after the process has been breached. An example is when the body temperature becomes too high or too low. At too high temperature, vasodilation of the skin's blood vessels occurs and more heat is lost to the surrounding from the skin, sweat is also produced by sweat glands and evaporation of the seat causes cooling. At too low temperature, vasoconstriction occurs leading to the conservation of more heat. The muscles also shake to generate more body heat
Positive feedback ensures that a breach of body processes reaches completion. An example is when a pregnant woman starts laboring. The increase in the amount of oxytocin in the blood leads to the contraction of the uterus consequently leading to the opening of the cervix. More and more oxytocin leads to more frequent and stronger contraction of the uterus untill the baby is born.

Hi,
The correct answers should be:
Electrons are smaller than protons
The majority of an atom’s mass is in the nucleus
Protons and neutrons are about the same size.
The first option is not true since in the picture you can see three different kinds of particles, while the second one is false since different electrons can occupy different energy levels and the same electron can “jump” from one energy level to another one if stimulated.
Hope this helps! If my answer was not clear enough or you’d like further explanation, please let me know. Also, English is not my first language so I’m sorry for any mistakes.
True, they can strategize where to put the food, know whats supposed to be in their environment, and make sure other animals don't take it
