Any element's atomic number represents the number of protons it contains (D). The mass, weight, and sum of protons and neutrons can change for various isotopes a single element, but any isotope of a single element has the same number of protons.

I hope this helps.

What is the key difference between age polyethism and reproductive division of labor in honey bees? ento 320?
Colt1911 [192]
The key difference between age polyethism and reproductive division of labor in honey bees is their age and functions, younger bees work inside the honeycomb, they have several duties, such as feeding the larvae, cleaning, thermoregulate the inside and receiving the nectar from the older bees, through trophalaxy (mouth contact), those bees are in charge of the guard an cleaning of the outside, besides helping with the honeycomb ventilation.

A cell containing only pure water is placed into a solution containing 1M sucrose. The cell's membrane is impermeable to water,
sesenic [268]

Answer: b and e

Explanation:

Two solutions are isotonic to each other if the have the same osmotic pressure.

Since the cell is impermeable to sucrose, sodium and chloride ion outside the cell, For the solution inside the cell to be isoosmotic to the solution outside the cell, same 1M of sucrose should be added to the solution inside the cell to balance osmotic pressure.

If osmolarity is the concentration of a solution expressed as the total number of moles per litre, also the addition of an ionic 0.5M Na+Cl- to the solution inside the cell will also balance the osmotic pressure.

0.5M if NaCl will dissociate and create an equivalent 1M osmotic pressure inside the cell.

If flies that are heterozygous for all three traits are crossed, what proportion of the offspring would you expect to be heteroz
Archy [21]

Answer:

\frac{1}{8}

Explanation:

If flies that are heterozygous for all three traits are crossed; e.g HtHtHt crosses with HtHtHt. The proportion of the offspring that would be expected to be heterozygous for all three traits will be: 1/8 because 50% (0.5) of their offspring will be heterozygous for just one trait. Therefore for three traits; we have (0.5)³= 0.125

0.125 is equivalent to \frac{1}{8}

From the table, the area of the asterisk region illustrate the traits that are heterozygous in the offspring.

= \frac{8}{64}

= \frac{1}{8}

Based on this information, how is the ath operon most likely controlled
grin007 [14]
Digestion of the sugar athelose in this theoretical framework is controlled by an operon that displays both positive control and negative control. Translation of the ath operon is turned on when athelose is available, and accelerated when the bacterium comes up short on glucose and must depend on athelose for vitality.
