Answer: Endocrine system
Explanation: The integumentary system is that is made up of the skin, hair, nails and the Endocrine glands. The following functions of the integumentary system are:
a. It protects skin from any form of damage which could be in form dehydration.
b. It protects the skin by secreting an hormone called melanin which protects the skin from ultra violet radiation.
c. The integumentary system helps in regulating and maintaining the body temperature
d. The skin which is part of the integumentary system secretes Vitamin D which is an essential in building of strong and healthy bones.
Answer:
Tilling breaks the natural structure of the ground by exposing the organic matter, accelerates mineralization, and pollutes.
Explanation:
Organic matter, together with porosity and humidity directly influence in the recovery of the soil structure and stability when these are exposed to different mechanical treatments or actions. Porosity and soil matrix continuity directly influence in the hydraulic conductivity and interchange water and air processes.
Tilling systems affect the productivity of the crops, and the physic, chemical and hydraulic characteristics of the soil. Tilling modifies the superficial layer of soil, alters the continuity of porosity and reduces the amount of organic matter in the ground.
Intensive use of tilling contributes severely to the carbon emission. Carbon is stored in the soil and when this last one is altered by tilling, carbon is exposed and released out in the open, becoming CO². This gas is one of the gases of the greenhouse effect and one of the causes of global warming.
Intense tilling breaks the natural structure of the ground by exposes the organic matter, it accelerates mineralization, and it pollutes.
Answer:
D but I'm not completely sure
Atoms can join together to make molecules. A single atom is made from protons, neutrons and electrons. A molecule is a group of atoms bonded together. Atoms is some thing which can't be split
<span>Molecule can be divided into many atoms. I know you dont need this but hey it may help someone else. ooops i put it in the wrong section</span>
Answer:
FALSE
Explanation:
Ionization energy is the minimum amount of energy required to discharge an electron from its orbital shell from an atom in ground electronic state. The closer the electron, that is to be discharged, is to the nucleus of the atom, the harder to remove it hence has high ionization energy. In addition, if the nucleus of the atoms has a higher mass and the electron is even closer, the higher the ionization energy.
