telo118 [61]

Answer:

<h2>(14+16)/1000 *100= 3</h2>

Explanation:

Parental combinations are always more common then other recombinant progenies.

A female fly is heterozygous for three X-linked genes crossed with an abc/Y male. . If single crossover occurs between a & b  and between b & c, then the double cross is that, which occurs in both.

Double cross over progeny are always least in number, so here double cross occurs are in abC 14 and ABc 16.

So we are expecting that number of double cross over progeny= (14+16)/1000 *100= 3

Are Potassium hydroxide, Cesium hydroxide and Calcium hydroxide weak bases, strong bases, or acids
VladimirAG [237]

Strong bases

KOH, CsOH and Ca(OH)₂ are all strong bases because they dissociate completely in aqueous solution.

A base is a substance that produces excess hydroxyl ions in aqueous solutions.

Strong bases would dissociate completely when in solution.

Bases of alkali and alkali earth metals are classified as strong because they exhibit full ionic characteristics.

Wind can use sand as a blank to wear away rock
Gekata [30.6K]

Wind can use sand as an abrasive to wear away rock.

Option (d);

<u>EXPLANATION: </u>

  • Rocks are broken down into smaller pieces with sand or water flowing over the rocks at a great speed.
  • Many solid particles like soil, sand, mud, etc. move down the rocks by downhill or wind blowing in the downward direction and called wind abrasion.
  • Sand blown with the help of high speed, sandblast away the rocks.
  • Abrasion is a process in which sand is blown in downwards direction with the help of wind and that wears away the rock's surface over time.
  • Thus, wind uses sand as an abrasive to wear away a rock.
