Answer:

Because the tongue is a muscle. Muscles can be involuntary(moves without control) or voluntary(controlled). Necessarily, the tongue is not an involuntary muscle, but the tongue not staying still, scientifically, can be a sign of lacking energy.

<h3>What is DNA methylation?</h3>

Adding methyl groups to the DNA molecule is a biological process known as DNA methylation. Methylation has the ability to change a DNA region's activity without changing the sequence.
When DNA methylation takes place at a gene promoter, it frequently decreases gene transcription.
DNA methylation plays an important role in a number of critical processes in mammals, including aging, cancer, X-chromosome inactivation, genomic imprinting, and transposable element repression.
The majority of eukaryotic genomes contain DNA methylation, a dynamic epigenetic alteration. It is well recognized to cause a high rate of CpG to TpG mutations.
However, nothing is known about the connection between the rate of germline mutation and the dynamics of methylation during germline development.

Which type of motor units are activated for the longest time during low to moderate level exercise?

Furkat [3]

Motor unit refers to the functional element of muscle contraction during an exertion. There are two basic types of motor unit: large and small motor units. During low to moderate level exercise, small motor units are activated. Small motor units are recruited during sustained activity; is made up of high proportion of type 1 muscle fibers, which are resistant to fatigue

The trait for medium-sized leaves in iris is determined by the genetic condition PP'. Plants with large leaves are PP, whereas p

loris [4]

Answer:

See the answer below

Explanation:

Medium size leaves genotype = PP'

Large leaves genotype = PP

Small leaves genotype = P'P'

Red flower genotype = RR

Pink flower genotype = RR'

White flower genotype = R'R'

Two plants each with medium-sized leaves (PP') and pink flowers (RR') were crossed.

PP'RR' x PP'RR' (let PP' = Aa and RR' = Bb)

Progeny and expected phenotypes

1 PPRR - large leaves, red flower = 1/16 x 640 = 40 seedlings

2 PPRR' - large leaves, pink flower = 2/16 x 640 = 80 seedlings

2 PP'RR - medium leaves, red flower = 2/16 x 640 = 80 seedlings

4 PP'RR' - medium leaves, pink flower = 4/16 x 640 = 160 seedlings

1 PPR'R' - large leaves, white flower = 1/16 x 640 = 40 seedlings

2 PP'R'R' - medium leaves, white flower = 2/16 x 640 = 80 seedlings

1 P'P'RR - small leaves, red flower = 1/16 x 640 = 40 seedlings

2 P'P'RR' - small leaves, pink flower = 2/16 x 640 = 80 seedlings

1 P'P'R'R' = small leaves, white flower = 1/16 x 640 = 40 seedlings
