All your cells have the same genes. True or false?

QUESTION POSTED AT 18/01/2020 - 06:40 AM

Answered by admin AT 18/01/2020 - 06:40 AM

That is True! As it says here on a website:All the cells in a person's body have the same DNA and the same genes. However, the difference between cells in different tissues and organs is that the "expression" of the genes differs between cells.

Suppose that a when a cell phone store charges 16$ for a car charger, it sells 92 units. When it drops the price to 15$ it sells 96 units. Assume that demand is a linear function of price. If each phone charger costs 1$ to make, what price should the store charge to maximize its profit? If x is the number of times the price is reduced by one dollar. Find a function for total profit with respect to x. A negative value for x will mean the price is increased. ...?

If you put the dollar decrease as x, you sell charge
16−x

dollars and sell
92+4x

units for a profit of
(16−x)(92+4x)−(2+4x)

dollars. the last subtraction because your cost is $1 per unit multiply out and
get
P=−4x2−32x+1470

which will have a maximum at the vertex
x=−b/2a

32/(2(−4)) 

= −4

Which one of these is not an example of intracellular communication A. Molecule in a cell changes function of cell B. Control of cell division C. Molecular movement within a cell D. Reaction to pheromones

Answer:

The answer is Reaction To Pheromones

Explanation:

This is not an example of intracellular communication because Airborne molecules that elicit a reaction in a member of the same species are called pheromones, and the most famous ones are potent aphrodisiacs, like androstenone and androstenol in the saliva of male boars.

Explain how the inside of a cell remains separate from its environment

     Well, first, we need to know the structures of a cell to answer this question properly.

      As you may know, a cell contains lots of different structures with different functions, for example, a ribosome, it is an organelle that makes protein for your body. The inside of a cell is separated then by a plasma membrane made out of phospholipids, it protects the inside of a cell by deciding what gets in and what gets out through proteins attached to it and vesicles. The inside of a cell must be always separated from its environment because of the difference in pH levels most of the times, or even to maintain its functions working properly without outside influences.

Iso mean  equal , there is no change in the cell .

For example iso-gametes

It means the gametes are same .All gametes are same and are not different with each other.

Isomer : It means that the compound which have same molecular formula but different structural formula .

Therefore, we can say that iso mean same or equal or identical or  like or similar .

Hence, the given statement is true.
