Surface tension in water owes to the fact that water molecules attract one another, as each molecule forms a bond with the ones in its vicinity. ... This inward net force causes the molecules on the surface to contract and to resist being stretched or broken.
They observe it, run tests on many different things, and do expirments
Metamorphosis is a type of homeostasis. A. is the correct answer.
Answer:
The options are:
A. Gravel
B. Sand
C. Silt
D. Clay
E. Mud
The answer is A. Gravel
Explanation:
Meiofauna are small benthic invertebrates which live in aquatic habitat. They are suited for both marine and fresh water environments.
Gravel aren’t tightly packed together in large quantities when compared with the other options such as sand, silt, clay, mud. This makes it possible for more aeration and the presence of more oxygen at the soft-bottomed intertidal community.
Answer:
F,T,T,F
Explanation:
1)false-(its a covalent bond)
A water molecule is formed when two atoms of hydrogen bond covalently with an atom of oxygen.
2)True-(water is a polar molecule)
Water is a polar molecule because the positive end attracts particles of negative charge.
3)True
water dissociates to form hydrogen ions (H3O+) and hydroxide (OH-) ions
4)false
Lower pH number means stronger acid, higher pH number means stronger base.
