Answer and Explanation:

When a cell is freezed, it cytoplasm-which is mostly water- is frozen and its volume expands. In consequence, pressure inside the cell increases and that causes damage to the outer wall.

The same occur in an unopened softdrink when it freezes. The volume inside the container increases and the pressure increases. If this volume increment is not considered before freezing the liquid, it could cause the container damage or breaking.

PLEASE help me I have NO IDEA what this means....

That is sooo false, that doesn't make sense!
The real continental drift Wegener theory was that similar fossils were found on different continents. (this is a very brief explanation of one of his theories.)

Hope this helps!

Please crown;)

yuradex [85]

Question is incomplete. Complete question is as follows:

All cells have

A. a covering called a plasma membrane that surrounds the cell and controls what information and materials enter and leave it.

B. An internal fluid that gives shape to the cell and supports the other things within it .

C. A central zone or nucleus that contains the cell's genes.

D. All of the above

Answer:

D. All of the above

Explanation:

All cells have a protective covering called plasma membrane. It allows the entry and exit of selective materials. Some cells can have an additional layer outside it which is called cell wall. For example, plant cells.
All cells have an internal fluid where the components of the cell float. It is called cytoplasm or protoplasm. It maintains the shape of the cell and also provides a structure to it.
All cells also have a zone where the genetic material is present. The genetic material is ultimately responsible for keeping the cell alive and forming various proteins. In prokaryotic cell it is present just in a zone in cytoplasm. In eukaryotes it is present inside an organelle called nucleus.
Hence, all the above things are present in each cell.

7. What is the correct order of the levels of organization in the human body from

Alexxandr [17]

Answer:

The major levels of organization in the body, from the simplest to the most complex are: atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism.

All living and non-living things are made of one or more unique substances called elements, the smallest unit of which is the atom, (for example, the element oxygen (O) is made of O atoms, carbon (C) is made of C atoms and hydrogen (H) is made of H atoms. Atoms combine to form molecules.

All living structures are made of cells, which are made of many different molecules. Cells are the smallest independent living thing in the human body. The body is made of many different cell types, each with a particular function, (for example muscle cells contract to move something, and red blood cells carry oxygen). All human cells are made of a cell membrane (thin outer layer) that encloses a jelly-like cellular fluid containing tiny organ-like structures called organelles.

A tissue is a group of similar cells that work together to perform a specific function. There are four main tissue types in humans (muscular, epithelial, nervous and connective). An organ is an identifiable structure of the body composed of two or more tissues types (for example, the stomach contains muscular tissue made of muscle cells, which allows it to change its shape, epithelial tissue which lines both the inner and outer surface of the

stomach, nervous tissue which sends and receives signals to and from the stomach and the central nervous system, and connective tissue which binds everything together).

Organs often perform a specific physiological function (for example, the stomach helps digest food). An organ system is a group of organs that work together to perform a specific function (for example, the stomach, small and large intestines are all organs of the digestive system, that work together to digest foodstuff, move nutrients into the blood and get rid of waste). The most complex level of organization, the human organism is composed of many organ systems that work together to perform the functions of an independent individual.

Alex

Observe birds nesting in cut patches and uncut patches of forest.
-Hypothesize that more birds nest in cut forest patches.
-Develop a plan for conducting nest counts in several similar-sized patches of cut and uncut forest.
-Count the number of nest found and record the data.
-Compare the data collected concerning nests from cut and uncut patches of forest.
Determine whether more birds nest in cut or uncut forest patches and share this conclusion with other researchers.
