Answer:
There are 4 different fundamental states of matter: solid, liquid, gas, and plasma.
The atoms/molecules that make up a solid are packed <u>tightly</u> together and arranged in regular, repeating patterns. They are held firmly in place by their attractive forces and their <u>low kinetic energies</u> but do vibrate within a limited area. Solids, have a <u>fixed</u> shape and volume.
In liquids, the atoms/molecules have a moderate kinetic energy and flow easily around one another. They are kept from flying apart by attractive forces between them. Liquids have a fixed <u>volume</u> but assume the <u>shape</u> of their containers.
Atoms/molecules in gases fly in all directions at great speeds. Due to this <u>high</u> kinetic energy, attractive forces between them are <u>insignificant</u>. Gases assume the volume and shape of their containers.
Lastly, plasma is the state of matter with the highest thermal energy. It is made up of free electrons and the positive ions from which they came. The electrons freely move around within this system of positive ions in a similar way to <u>gases</u> . Plasmas are strongly influenced by electric and magnetic fields due to the charged particles.
Answer:
Both differentiated cells and sex cells generally do not undergo mitosis past a certain phase of development. These differentiated cells include neurons, myocytes (muscle cells), keratinocytes (skin cells), and most blood cells, including B-cells, T-cells, and red blood cells.
Explanation:
The type of plant that grows near the river
According to the United States Department of health and human services, in order to obtain sufficient physical activity for health, the Americans should perform the following activities:
1. 75 minutes per week of vigorous-intensity activity.
2. 150 minutes per week of moderate intensity activity.
3. Or, an equal combination of both moderate and vigorous-intensity activity
Answer:
Option D
Explanation:
Pentose in Pentose sugar contains the root word "penta", meaning 5 sides, and so it must be the shape labeled C.
