Answer:
Agree
Explanation:
Theories are refined and then become laws and laws are somehow more important than theories. In science actually what a law is, is a descriptive generalization. So we talk about the laws of thermodynamics that tell you about heat under different circumstances.
I believe this is the best one:
B. The volume of water will increase if cooled from 3°C to 2°C.
I don't think D) because water expands from 4°C to 0°C
"When liquid water is cooled, it contracts like one would expect until a temp of approximately 4 degrees Celsius is reached. After that, it expands slightly until it reaches the freezing point."
Answer:
The electron configuration for this atom is Calcium, which has 2 valence electrons.
Explanation:
Following the periodic table and with the electron configuration, you will end up with calcium, which has 2 valence electrons. (Always follow the electron configuration from left to right! It begins at hydrogen, then to helium... and so on.)
1s2 -> He....
2s2 -> Be....
2p6 -> Ne...
3s2 -> Mg...
3p6 -> Ar...
4s2 -> Ca.
Answer:
----------------------------------------------
Reproduction is defined as the production of individuals of the same species, that is the next generation of the species.
----------------------------------------------
There are basically two types of reproduction - asexual and sexual.
----------------------------------------------
Asexual reproduction involves only one parent and the offspring is
genetically similar to the parent ...
----------------------------------------------
The different types of asexual reproduction are fission, budding, fragmentation, spore formation and vegetative propagation.
----------------------------------------------
Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete (such as a sperm or egg cell) with a single set of chromosomes combines with another to produce a organism composed of cells with two sets of chromosomes .
Asexual reproduction is a type of reproduction which does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from a single cell or from a multicellular organism inherit the genes of that parent.
