Answer:
The cell membrane is selectively permeable, which controls the movement of materials in and out of the cell by passive and active transport.
Explanation:
According to this question, animal cells are made up of the following contents: 90% water and 10% protein, carbohydrates, nucleic acid, lipids and other molecules. The cell regulates this internal composition in a stable way via a process called HOMEOSTASIS.
The animal cell is able to regulate or maintain a stable internal composition by the possession of a selective permeable membrane called CELL MEMBRANE. The cell membrane is semi-permeable in the sense that it allows the entry of some molecules into and out of the cell and blocks others.
Some molecules are allowed by the cell membrane without the need for energy input in a transport called PASSIVE TRANSPORT while some requires energy input in a transport called ACTIVE TRANSPORT.
A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter. The word galaxy is derived from the Greek galaxias, literally "milky", a reference to the Milky Way.
Elliptical: These have a faint, rounded shape, but they're devoid of gas and dust, with no visible bright stars or spiral patterns. ...
Spiral: The Milky Way is one of the larger spiral galaxies. ...
Irregular: These are small, faint galaxies with large clouds of gas and dust, but no spiral arms or bright centers.
Answer:
I would expect to see a greater variety of traits observed. Simplistically, I would expect to see people with blue eyes and brown hair, blonde hair or red hair. Whereas in a population where chromosomes do not cross over, I would expect to see traits that are more frequently associated with each other. For example, I would expect to see a greater proportion of blue eyed people to be blonde because the gene for hair colour is more frequently associated with the gene for eye colour.

Answer:
9 : 3 : 3 : 1
Explanation:
If you want to be sure test this ratio, if you multiply 84 by 3, it nearly give you 242. Why by 3 ? Simple, just because the multiple of 9 : 3 is 3.
Explanation:
Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. ... These structures include: chloroplasts, the cell wall, and vacuoles.
