Matter can exist in one of three main states: solid, liquid, or gas.
Solid matter is composed of tightly packed particles. A solid will retain its shape; the particles are not free to move around.
Liquid matter is made of more loosely packed particles. It will take the shape of its container. Particles can move about within a liquid, but they are packed densely enough that volume is maintained.
Gaseous matter is composed of particles packed so loosely that it has neither a defined shape nor a defined volume. A gas can be compressed
liquid: A substance that flows and keeps no definite shape because its molecules are loosely packed and constantly moving. It takes the shape of its container but maintains constant volume.
gas: A substance that can only be contained if it is fully surrounded by a container (or held together by gravitational pull); a substance whose molecules have negligible intermolecular interactions and can move freely.
solid: A substance that retains its size and shape without a container; a substance whose molecules cannot move freely except to vibrate.
Answer:
D
Explanation:
In those two gaps. After the two gaps It is written as Bonds. That 1,2,3 answers are not correct
Answer:
To maintain body homeostasis
Explanation:
The endocrine system consists of the endocrine glands that release hormones directly int the blood. Those hormones bind to their receptors on the target cells and thus regulate their function. The major glands are:
pineal gland-releases melatonin, controls sleep cycle
pituitary gland-control growth, blood pressure, thyroid glands and metabolism etc.
pancreas-secretes insulin and glucagon, control of blood sugar levels
ovaries, testes-reproductive role (release female and male hormones)
thyroid gland-controls metabolism and protein synthesis
parathyroid gland-controls Ca levels
hypothalamus-connects nervous and endocrine systems, controls other glands
adrenal glands-release adrenalin and steroid hormones.
ISDN uses digital transmission encoding scheme known as 2 binary 1 quaternary or 2B1Q. The 2B1Q means that there are four possible signal levels and that each signal level encodes two bits of information.
Hope this helped :)
<span>The correct answer is multinucleate tissues, occurring naturally during the physical body work in conjugation with the plasma of the membranes of the cells. In summary, the skeletal cells are multinucleate because they are the result of the union between the muscular cells and the soft cells of the muscle. The reason they are multinucleate is because they facilitate the circulation of stem cells during the most demanding muscular movements. Stem cells help multinucleate tissue communicate faster.</span>
