Answer:
Plant cells have a cell wall, as well as a cell membrane.
Explanation:
In plants, the cell wall surrounds a cell membrane. This gives the plant cell its unique or rectangular shape. animal cells simply have a cell membrane, but no cell wall.
The first answer is c by decomposition.
The second one is c too dunes.
hope this helps :)
Answer:
Both (b) and (c)
Explanation:
Fats, steroids and waxes are some of the most common types of lipids. Lipids are non-polar hydrocarbons because of the presence of non-polar carbon-carbon and carbon-hydrogen bonds in there structure.
Generally, polar molecules are soluble in water while non-polar molecules are insoluble in water, hence, lipids do not dissolve in water. There non-polarity also makes them a suitable component in the selectively permeable biological cell membrane.
Answer:
The correct answer is option B) "computers are not as trustworthy as actual prototypes are"
Explanation:
It is false to affirm that results obtained from computer simulations towards looking for solutions of real-world problems are not as trustworthy as results obtained from actual prototypes. In most cases, computer simulations had proved to be reliable, particularly when the programers use validating arithmetic and algorithms. There are multiple companies dedicated to develop computer simulations to solve real-world problems, which are constantly used and tested in scientific investigations.
