A. a new disease develops , so having more genetic variation among there off spring is an advantage.
B. a new type of pray arrives in the environment , so they have more food sources.
C. a short and mild winter makes the environment more livable for them and all the other organisms in the area.
D. they migrate to a new location where prey and shelter are more abundant and easier to find.
Answers
Answer:
Answer A:
a new disease develops , so having more genetic variation among there off spring is an advantage.
Not 100% sure but A seems the most likely answer.
Explanation:
The question is asking where sexual reproduction is more of an advantage and I'd say that having more genetic variation would be caused by sexual reproduction and not as much or at all in asexual reproduction.
with B, C, and D. It wouldn't really be an advantage to do one or the other in this context.

Knowing an object's position requires which of the following? A. speed B. time C. displacement D. reference point
Answers
Knowing an object's position requires the (D) reference point
Reference point is the starting point use to locate another place or object. an object's position depends on reference point.
Position describes the distance and direction from reference point for an object. position of an object's is the location to the reference point.
Displacement is the difference between the initial position and the final position.
Speed is defined as the distance an object travels per unit time.
Time is defined as the duration of an object travels to cover a distance.
so according to all , reference point is needed to determine the position of an object's.
Thus, Knowing an object's position requires the (D) reference point

All alkalis are bases but not all bases are alkalis. True or False?
Answers
Answer:
A substance that neutralizes an acid is generally called a base and the basic substances that are soluble in water and alkali and the properties of alkalis are due to these hydroxide ions(OH−). ... - Thus, conclusively it can be said that all alkalis are bases but all bases are not alkali.
Answer:
This is false
Explanation:
it is actually the opposite, all bases don't dissolve in water, but alkali is a base that does dissolve in water. So, alkalis are bases, but not all bases are alkalis

three moles of sodium carbonate are mixed with two moles of lead nitrate in aqueous solution, leading to formation of a solid precipitate. how many moles of spectator ions remain in solution, assuming 100% yield of the precipitate?
Answers
There are 4 moles of spectator ions that remain in solution.
The equation of the reaction is;
Na2CO3(aq) + Pb(NO3)2(aq) -------> PbCO3(s) + 2NaNO3(aq)
We have to determine the limiting reactant. This is the reactant that yields the least amount of product. Note that the spectator ions are Na^+ and NO3^- that form NaNO3.
For Na2CO3
1 mole of Na2CO3 yields 2 moles of NaNO3
3 moles of Na2CO3 yields 3 × 2/1 = 6 moles of NaNO3
For Pb(NO3)2
1 mole of Pb(NO3)2 yields 2 moles of NaNO3
2 moles of Pb(NO3)2 yields 2 × 2/1 = 4 moles of NaNO3
We can see that Pb(NO3)2 is the limiting reactant.
Since [NaNO3] = [Na^+] = [NO3^-], it follows that there are 4 moles of spectator ions that remain in solution.

Based on location in the periodic table, which element has chemical properties that are most similar to iodine
xenon (Xe)
calcium (Ca)
Selenium (Se)
fluorine (F)
Answers
Answer:fluorine
Explanation:
Based on location in the periodic table, fluorine (F) has chemical properties that are most similar to iodine.
In the periodic table, elements are classified in groups and periods. The elements in the same group are chemically similar and they have the same number of valence electrons. Elements in the same period have the same highest energy level.
Hence, when looking for an element that is most chemically similar to iodine, we have to consider the element that is in the same group with iodine.
Both fluorine are iodine are both in group 17 hence, fluorine is most chemically similar to iodine.
