The answer is B. Nitrogen base
The sides of the DNA ladder are made of alternating sugar and phosphate molecules, the sugar being deoxyribose. The rungs of the ladder are pairs of four types of nitrogen bases (adenine, thymine, cytosine, and guanine)
Hope this helps :)
Answer:
Following are the answer to the given points:
Explanation:
- Unlinked - Nonrecombinant progeny (50%), recombinant progeny (50%)
- Fully related genetics - 100% non-recombining genetic progeny (parental)
- Incomplete connection of genes > 50% non-recombinant progeny < 50% crossover offspring. Connected genes
Mendel had established some essential concepts concerning inherited mechanisms such as the patterns of transmission of genes to offspring depending on their chromosomal placements. This same notion of linkage was offered to describe the pattern of the legacy of alleles on its chromosomal position.
Two different chromosomes have specific isoforms – for example, A and B which have two different features. As just a result, 50 percent of gametes are parental throughout type AB, and the other 50 percent of a recombinant in zygotes are quasi (aB & Ab) and 50 percent of the progenies that outcome from this mixture of gametes, therefore, are nonrecombinant in 50% and the cloned in 50 percent of the genetic makeup AaBb.
With two fully linked genes, e.g they exist on the very same chromosome and no cross-over occurs, all gametes are similar to parent types (AB and ab), like they do not split themself nor are diverse and culturally produced (nonrecombinants).

Animals depend on food and without food it will break our animal food source chain. for example cows depend on hay and lions depend on meat from cows or something like that
Answer:
When fresh water reaches lakes and shores , it becomes dirty and less diverse in living organism.
Explanation:
Fresh water originating from a given source is usually cooler at upstream side. Also it has high oxygen content and fresh water fauna such as fishes. In the middle of its course, its width and species diversity increases. With further progression, sediments and dust adds to the water thereby reducing its clarity and hence the penetration of sunlight. By the time this water reaches streams and ponds, it is full of mud, sand, and other sediments.
