Explanation:
Nucleus Cytoplasm
Contains the genetic material (DNA) Contains a thick gel-like substance
The most obvious structure in the cell Contains all organelles
Contains directions for cell regulation Mostly water
The nucleus is a large and obvious organelle in the cell and it provides instructions for the regulation of the cell's activities and it contains the genetic material (DNA). All organelles are embedded in the cytoplasm which is made up of mostly water.
The B vitamins and vitamin C are absorbed along with water in the small intestine and then circulate through the blood.
Answer:
Changes of state are physical changes. They occur when matter absorbs or loses energy. Processes in which matter changes between liquid and solid states are freezing and melting. Processes in which matter changes between liquid and gaseous states are vaporization, evaporation, and condensation.
Answer:
Homo species have differences in brachial index, face and teeth size as compared with australopithecines.
Explanation:
Australopithecines were found in pleistoocene era and adapted to the bipedal locomotion but shows differences in walking style as compared to early homo species. They have large brachial index. The postcanines were large but incisors and canines were small.
Early homo species were found around 2 million years ago. They shows bipedal locomotion with different walking styles. The brachial index of early homo species was small as compared with the australopithecines. The post canines were small but incisors and canines were large.
Answer:
luster, streak, hardness, cleavage, fracture, and crystal form are the most useful physical properties for identifying most minerals. Other properties-such as reaction with acid, magnetism, specific gravity, tenacity, taste, odor, feel, and presence of striations-are helpful in identifying certain minerals.
