Sensory neurons are the neurons responsible for receiving the information from the environment or the stimuli. This sensory neurons pass the message thru interneurons and then to Central Nervous System (brain and spinal cord) which then sends the signal to the motor neuron. </span>
A nail may be considered as an achiral object because it can
be superimposed when it is faced in a mirror image where in it may look exactly
the same rather than chiral when they are in a mirror image, it wouldn’t be
superimposable.

Answer:
1.) Inflated pod shapes (Cc) in the F1 generation
2) See attached image for the work out of the cross from P generation to F2 generation.
3). CC- 1/4, Cc- 1/2, cc- 1/4
Explanation:
This question is related to the pod shape trait encoded by a single gene in pea plants. The alleles for inflated pod shape (C) is dominant over the allele for constricted pod shape (c). This means that allele "C" will be expressed over allele "c" in a heterozygous state.
The two truebreeding parent plants will have genotypes: CC (inflated pod shape) and cc (constricted pod shape). When these two plants are crossed, an all heterozygous plant with genotype: Cc will be formed in the F1 generation. Since, C is dominant over c, the F1 Cc plants will have an inflated pod shape phenotype.
The F1 Cc plants are self-crossed to produce the F2 generation offsprings i.e. Cc × Cc. The gametes C and c will be produced by each F1 parent, which will be used to draw a punnet square (see attached image). From the cross, offsprings with genotypes: CC, Cc and cc are produced in the F2 generation.
CC (phenotypically inflated pod shape)- 1/4
Cc (phenotypically inflated pod shape)- 1/2 or 2/4
cc (phenotypically constricted pod shape)- 1/4
Answer:
By making a paternity test by Short tandem repeats, or STRs (microsatellites).
Explanation:
Short tandem repeats, or STRs, are microsatellites consisting of repeated sequences of 2 to 6 base pair length monomers in tandem, and most of them have a high degree of polymorphism. Half of an individual microsatellites are inherited by each parent, and they can be assesed by PCR amplification and further electrophoresis.
In this case, you would try to recover a bone from the remainings of the woman, the Tsar and his wife, since the rest of the latest were in a shallow grave with many different individuals. Preferably, you should manipulate this samples in an ancient DNA facility (aDNA) with proper techniques. You clean the bone samples, drill them, and from internal bone powder make a DNA extraction. After this, you perform a series of PCR targeting a panel of STRs, and electrophoresis. If the woman claim is true, half of her microsatellites should have correspondence with the Tsar, and half with the ones of his wife.
