Crossing-over of chromatid segments during meiosis division I results in the formation of genetic variation.
<span>Crossing-over is an event during the meiosis (during prophase I)<span> and represents the exchange of genetic material between non-sister chromatids of homologous chromosomes. As a result of it, the creation of new combinations of genes on each chromosome occur. The exchange can happen many times within the same pair of homologous chromosomes, creating unique combinations of alleles.</span></span>

Crossing over of chromatid segments during meiosis division 1 results in new gene combinations.  Cross over occurs between prophase 1 and metaphase 1 and is the process where homologous chromosomes pair up with each other and exchange different segments of their genetic material to form recombinant chromosomes. Additionally, it can happen during mitotic division ; which may result in loss of heterozygosity.

Pavlova-9 [17]
<span>An electroencephalogram (EEG) machine EEG machine works by tracking and recording electrical activity of the brain in form of wave pattern. The instrument has electrode discs which are placed on ones scalp and then the electrical activity of the brain is detected and signals send to the computer which shows the result in form of a wave pattern. The doctors can there be able to detect any abnormal wave pattern and be able to diagnose if one is having seizure, stroke, tumor, epilepsy, brain death, coma or any other brain related abnormality.</span>

The pattern of transcription for a pair of identical twins (Tweedledee and Tweedledum) is very similar at the age of 10. However
aivan3 [116]

Answer:

Explanation:

My best bet is DNA methylation at the site of Tweedledum's leptin gene or Histone Acetylation at the site of Tweedledee's gene.

B/c DNA methylation is a process by which methyl groups are added to the DNA molecule. Methylation can change the activity of a DNA segment without changing the sequence. When located in a gene promoter, DNA methylation typically acts to repress gene transcription. So this is probably repressing Tweedledum's leptin gene trancription which is not happening in Tweedledee.

Additionally, Histone Acetylation at site of Tweedledee's gene increases her trancription b/c Histone acetylation causes DNA to be more accessible and leads to more transcription factors being able to reach the DNA. Thus, acetylation of histones is known to increase the expression of genes through transcription activation.

Please help me out :( !! Compare and contrast mutualism, commensalism, and parasitism. Use clear and complete sentences.
stiks02 [169]

Answer:

Mutualism is where both organisms benefit, commensalism is where one benefits but the other organism isn’t harmed, and lastly, parasitism is where one organism benefits and the other is harmed. The various species found within a single ecosystem can relate to each other in a variety of ways. The terms mutualism, commensalism, parasitism and symbiosis all refer to the various ways that species within an ecosystem can interact with one another.
