what is a physical change ?

the material involved in the change is structurally the same before and after the change.

what are the three proceses that shapes earth surface.


  • Erosion. Erosion involves the movement of rock fragments through gravity, wind, rain, rivers, oceans and glaciers.
  • Weathering. Weathering is the wearing down or breaking of rocks while they are in place.
  • Deposition. ...
  • Landforms. ...
  • Relief.

what is a main idea?

 the author's message about the topic.

what is a life cycle?

the developmental stages that occur during an organism's lifetime. In general, the life cycles of plants and animals have three basic stages including a fertilized egg or seed, immature juvenile, and adult.

what  do Animal cells, like other eukaryotic cells have?

they have a nucleus and other membranous organs.

what is the diffrerence between  chemical and a physical change?

In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed.

what causes a earthqauke"?.

sudden movement along faults within the Earth.

what is nonfiction?

writing that is about real events and facts, rather than stories that have been invented.

can a turtle go through a life cycle?

yes a turtle can go through a life cycle.

what are the the three main things in a animal cell.

 cell membrane, cytoplasm, and cell organelles. The organelles are covered with a plasma membrane.

chemical change.

  • Can wind travel faster than the speed of sound?

Yes, wind can travel faster than the speed of sound

what is fiction.

A fiction is a deliberately fabricated account of something

what do all cells have in common

All cells share four common components: (1) a plasma membrane, an outer covering that separates the cell's interior from its surrounding environment; (2) cytoplasm, consisting of a jelly-like region within the cell in which other cellular components are found; (3) DNA, the genetic material of the cell;

How does polarity develop de-novo in isolated plant cells?

The mechanisms to establish de novo cell polarity are likely to differ between systems, but all must begin with a symmetry breaking process to form the initial asymmetric cellular distributions, and followed by downstream feedback mechanisms to consolidate the asymmetry and to build polarized structures.

what is melting a physical chemical.

melting is a physical change.

  • What is the rock cycle, and how does it work?


The rock cycle is a web of processes that outlines how each of the three major rock types—igneous, metamorphic, and sedimentary—form and break down based on the different applications of heat and pressure over time. For example, sedimentary rock shale becomes slate when heat and pressure are added.

what is conflict?

the clash of opposing forces with a character's own pursuit of a goal.

  • How do individual differences occur within species of living things? •



Genetic variation within a species can result from a few different sources. Mutations, the changes in the sequences of genes in DNA, are one source of genetic variation. Another source is gene flow, or the movement of genes between different groups of organisme

400

What is the spectrum of cellular functions for membraneless organelles and intrinsically disordered proteins?

mRNA decay in P-bodies, mRNA storage in stress granules, mRNA splicing in nuclear speckles, and rRNA synthesis in nucleoli (29). Indeed, RNA acts as a potent, biologically important nucleator of intracellular phase separation

chemical

  • How has the surface of the Earth changed over time?

Some changes are due to slow processes, such as erosion and weathering, and some changes are due to rapid processes, such as landslides, volcanic eruptions, and earthquakes.

500

whats a brainstorm.

 a group problem-solving method that involves the spontaneous contribution of creative ideas and solutions.

Why are living things so different yet alike? • .

they all need something from their environment in order to survive, no matter if it is food, or a mate for reproduction.

500

How do plants deal with internal noise? How does order emerge in cells and propagate to organs and organisms from complex dynamical processes?

Plant cells communicate with each other via narrow channels embedded across adjacent cell walls. These channels, called plasmodesmata, allow molecules to pass between cells, thereby enabling plants to grow normally and develop tissues and organs.
