Answer:

Epigenetic effects can be caused by DNA heterochromatin and/or histone silence or activate.

As such, they can different chromosomes or certain chromosomal regions and be responsible for parental imprinting or influencing gene activity in oxidation and reduction.

Patterns of nucleotide demethylation and hypermethylation are often activate when cancer cells are compared to normal cells.

Explanation:

Cells acquire various patterns of gene expression during differentiation to adapt to a changing environment. Epigenetic and genetic alterations are considered as two independent mechanisms that participate in the onset and progression of cancer. Epigenetic mechanisms can be as important for biological events as genetic mechanisms, which do not imply a change in the DNA sequence, but do have an important role in the modification of gene expression.

Why do you need a minimum of three Seismic stations to determine the location of an epicenter

IRISSAK [1]

Single seismograph can register the occurrence of an earthquake. Analysis of the waves can yield the distance between the sensor and the epicenter. This describes a circle with the seismograph at the center. ... Adding data from a third station pinpoints the epicenter as the only place where all three circles intersect

Circadian rhythm refers to

strojnjashka [21]

Answer:

The correct option is B) a pattern of biological functioning that occurs on a 24-hour cycle.

Explanation:

Biological rhythm is defined as the regular variation of an organic function related to the course of time, circadian biological phenomena (around the day), are those with a period of approximately 24 hours.

Circadian rhythms are physical, mental and behavioral changes that follow a daily cycle (the biological rhythm), and that respond primarily to light and darkness in an organism's environment. This cycle close to 24 hours, allows to recognize the sleep-wake phenomena and their homeostatic action, in the systemic processes of every living being. The circadian system is composed of photoreceptors, pacemakers and efferent pathways that allow a regular functioning of the sleep and wakeful state.

Consider the genes for pea color (the "Y" gene) and pea height (the "T" gene). For the "Y" gene, the Y allele = yellow peas and

steposvetlana [31]

Answer:

9/16= tall and yellow offspring

Explanation:

Two dihybrid pea plants for color and height are crossed to obtain the progeny. The genotype of both the parents is "TtYy".

Each of the dihybrid parent will form four types of gametes in 1:1:1:1 ratio= TY, Ty, tY and ty. A random fusion of gametes from both the parents would give a progeny in following phenotype ratio=
