Answer:

In multicellular organisms, stem cells are undifferentiated or partially differentiated cells that can differentiate into various types of cells and divide indefinitely to produce more of the same stem cell. Stem cells are undifferentiated cells that can turn into specific cells, as the body needs them. Scientists and doctors are interested in stem cells as they help to explain how some functions of the body work, and how they sometimes go wrong.

Consider the results of a testcross performed on an organism heterozygous for 2 genes. For each scenario of gene arrangement for
emmasim [6.3K]

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).

Where is potential chemical energy stored?
kenny6666 [7]

Answer:

In the bonds between atoms

Explanation:

Chemical energy is stored in the bonds that connect atoms with other atoms and molecules with other molecules. Because chemical energy is stored, it is a form of potential energy. When a chemical reaction takes place, the stored chemical energy is released.
