Answer:
(B) Garden pea has 7 linkage groups, and Neurospora has 7.
Explanation:
<u>Number of linkage group is always equal to type of chromosomes.</u> In garden pea which is a diploid organism, there are 7 linkage groups because the homologous chromosomes of a pair are alike so even though the total number of chromosomes are 14 yet no. of linkage group will be 7.
Here, it may also be noted that <u>there is no separate male or female chromosomes i.e. no allosomic pair</u> in this organism which are usually different for males and lead to the increase in linkage groups. For example in human males out of the 23 pairs, we have 23rd pair which leads to the increase in linkage groups as compared to number of diploid sets of chromosomes. In human males, 22 pairs of chromosomes are alike but the 23rd pair is different which has 1 X chromosome and 1 Y chromosome which leads to a total of 22+1+1 = 24 linkage groups. In contrast to this, human females have only 23 linkage groups because in females 23rd pair of chromosome is XX in which both the X chromosomes are alike so it does not lead to an increase in linkage groups.
Neurospora crassa has 7 haploid chromosomes so the type of chromosomes and total number of chromosomes both are 7. Since type of chromosomes are 7, the linkage groups will also be 7 in this organism.
The normal amino acid for CTC is Leucine.
CAC codes to Histidine.
The correct answer is option D, that is, ice floating on the water surface.
The cohesive forces among the molecules of a liquid are accountable for the process called surface tension. Surface tension refers to the tension of the surface film of a liquid resulting due to the attraction of the particles in the surface layer by the bulk of the liquid that seems to reduce the surface area.
The examples of surface tension are walking of small insects on water, floating of a needle, the surface tension of water offers the essential wall tension for the creation of bubbles with water, and surface tension is accountable for the shape of liquid droplets.
The low density of ice makes it float at the liquid water surface, like ice cubes in a glass of water, or an iceberg. The lower density of water in its solid form is because of the way hydrogen bonds are aligned as it freezes, the water molecules are pushed further far away in comparison to the liquid water.
