11 and 12 seem to be right :) For 13, only organisms which are homozygotic for a certain gene (aa) express a recessive phenotype.
14. This dna exchange between the homologous chromosomes is called crossing-over.   
15. geneticly linked or coupled, the phenomenon is known as genetic linkage
16. and 17. also seem all right :)

What happens to the temperature of a sample of matter as it changes from a liquid to a gas?
irina1246 [14]
All matter can move from one state to another. It may require extreme temperatures or extreme pressures, but it can be done. Sometimes a substance doesn't want to change states. You have to use all of your tricks when that happens. To create a solid, you might have to decrease the temperature by a huge amount and then add pressure. For example, oxygen (O2) will solidify at -361.8 degrees Fahrenheit (-218.8 degrees Celsius) at standard pressure. However, it will freeze at warmer temperatures when the pressure is increased. i think

Use the mechanisms of meiosis to explain why most mules are sterile.
Tema [17]

Answer:

3. An even number of chromosomes are required for synapsis during prophase I and proper pairing during metaphase

Explanation:

Mules are hybrids of a cross between a female horse and a male donkey. Horses contain 64 chromosomes while donkeys contain 63 chromosomes in their somatic cells respectively. This means that they each produce 32 and 31 chromosomes respectively during meiosis. A mule, hence, contains 32+31= 63 chromosomes in their somatic cells.

This chromosome number in mules are uneven for meiosis to occur because meiotic division requires that an even number of homologous chromosomes pair together in a process called SYNAPSIS during prophase I of meiosis I. This is impossible in a mule because of the uneven number of chromosomes in its cells.

Also, during metaphase of meiosis, the homologous chromosomes need to be properly aligned at the equator for separation to occur. This is also impossible in a mule considering the number of chromosomes that don't add up.

Due to this reason of unevenness in the number of chromosomes present in a mule, meiosis will not occur and if meiosis (gamete formation) does not occur, reproduction cannot take place. Therefore, the mule is a sterile species i.e. cannot produce offsprings via sexual reproduction.
