Out of the statements presented regarding the skeletal system, the last one would be the only true statement which says that there are 3 components to the sternum bone.
For the number of vertebrae that cover the spinal cord, there are around 31 segments that have it. For the pairs of ribs, there are 12 pairs of it. There are also 14 major facial bones. As for the components of the sternum bone, there are 3 components which are as follows: the manubrium, the body, and the xiphoid process.

Answer:
When AraC binds to arabinose to initiate the process of transcription, then AraC is acting as an Activator.
Explanation:
Transcription is a process that help to produce messenger RNA from the DNA that is present in the nuceloids of bacteria cells. The production of these mRNA however, depends on the intracellular condition of the bacteria, for example, if there is a need for the protein coded for by the segment or not. In the case of this bacterium, the AraC can act as a repressor only when there is no arabinose sugar in the cell. In the scenario above, AraC will act as an activator because of the presence of the sugar arabinose.
The viruses that lie dormant in host cells until ready to multiply use : Lysogenic cycle
During the lysogenic cycle the virus do not kill the host. It integrate it's dna with the host's so it could lie dormant until it ready to multiply
Hope this helps
Answer:
The correct answer is -
Genotypes: 1 heterozygous dominant: 1 recessive
Phenotypes: 1 long hair cat: 1 short hair cat
probability: 50% chances of both long and short hair cats
Explanation:
It is given that long hair is a dominant represented by H, over the short hair represented by h. In the cross of a heterozygous cat for long hair with a cat with short hair, would produce H, h and h, h gametes respectively.
Cross: Hh × hh
H h
h Hh hh
h Hh hh
In this Punnett, there are two heterozygous long hair offspring produced and two short-hair cats.
So, Genotypes: 1 heterozygous dominant: 1 recessive
Phenotypes: 1 long hair cat: 1 short hair cat
probability: 50% chances of both long and short hair cats
