Top predators like lions, grey wolves, and great white sharks all share this trait. They eat virtually exclusively meat, and aside from humans, these animals don't have any other natural predators.

An organism that devour other plants or animals for energy and nutrients is termed as a heterotroph. The concept is derived from the Greek terms hetero, which signifies "other," and trophe, which indicates "nutrition." The two main classifications of organisms—autotrophs and heterotrophs—are depending on how they receive nutrition and energy.

Herbivorous animals are the main consumers (vegetarians). The organisms known as secondary consumers are carnivores that consume the prime consumers. The secondary consumers are commonly both more frequent and stronger.

If we are studying a histone complex that contains an unusually high level of modification with acetyl groups, then we can conclude about the nucleosomes containing this histone complex contain actively transcribed genes, i.e., they are subject to epigenetic regulation (Option E).

Epigenetic regulation is the control of gene expression due to chemical modifications in the DNA  and associated histones (methylation in the case of DNA, while histone modifications are diverse and they also include histone acetylation).

Therefore, with this data, we can see that epigenetic regulation also involves histone acetylation which is able to increase the transcription of genes by opening the chromatin structure in the heavily acetylated chromosome regions.

Complete question:

You are studying a histone complex that contains an unusually high level of modification with acetyl groups. What can you conclude about the nucleosomes containing this histone complex?

The portion of the small intestine that attaches to the cecum is the ileum.

At nearly 6 feet (1.8 m) in length, the ileum is the longest section of the small intestine.

The large intestine is the final portion of the digestive system and is where stool is formed. It is in this organ where a large part of the water and mineral salts are absorbed, some products are fermented and mucus is formed. The mucus has the function of compacting the fecal mass and contributing to its sliding.

The large intestine has a few main parts: cecum, colon, rectum, and anus. The colon is divided into the ascending colon, transverse colon, descending colon, and sigmoid colon.

Compared to the jejunum, it is thicker, more vascularized, and has more advanced mucosal folds.

At the ileocecal sphincter, the ileum connects to the cecum, the first segment of the large intestine (or valve).

The coiled tube of the small intestine separates into three sections. These are the duodenum, jejunum, and ileum, arranged from proximal (in the stomach) to distal.

The 25.4 cm (10 in) long duodenum, beginning at the pyloric sphincter, is the shortest section.

The jejunum connects the duodenum to the ileum and is approximately 0.9 m (3 ft) long (in life). The jejunum and ileum, the last section of the small intestine, do not have a defined boundary.

X-inactivation illustrates epigenetics.

Imprinted X-inactivation is a mammalian example of transgenerational epigenetic inheritance in which genes only on the paternally transmitted X chromosome are silenced.

Therian female mammals lose one of their X chromosome copies by a process known as X-inactivation, sometimes known as Lyonization. The packaging of the inactive X chromosome into the transcriptionally inactive heterochromatin structure silences it. X-inactivation prevents female animals, who almost always have two X chromosomes, from having twice as many X chromosome gene products as male mammals, who only have one copy of the X chromosome.

The anterior/posterior axis of the Drosophila embryo is organized by a concentration gradient created by the distribution of the bicoid (Bcd) protein.

It is known that bcd RNA is sequestered in the anterior pole during oogenesis, that it is not translated until fertilization, that it forms a protein gradient that works in the syncytial blastoderm after 9–10 nuclear divisions, and that it is then translated during the process of fertilization. The bcd maternal effect gene in Drosophila is responsible for encoding the homeotic protein bicoid. During Drosophila development, a gradient in the concentration of the homeotic protein bicoid shapes the anterior-posterior (A-P) axis. The first protein that was shown to function as a morphogen was bicoid. Although bicoid is crucial for the growth of Drosophila and other higher dipterans, it is lacking in the majority of other insects, where other genes fill its place.By activating transcription and repressing translation, the Drosophila protein bicoid (Bcd) regulates the expression of embryonic genes. The homeodomain (HD), which detects DNA patterns at target gene enhancers and a particular sequence interval in the Caudal (CAD) mRNA 3' untranslated region, is necessary for both of these roles.

Diverse transcription beginning sites produce structurally different RNAs in the Drosophila melanogaster Antennapedia gene. Transcripts are generated from each piece of the split Antp locus when the two locations are separated by a chromosomal inversion, and these RNAs start at the same nucleotide as in animals of the wild type.

Therefore, separate promoters control the initiation sites. By using in situ hybridization, we demonstrate that transcripts from each promoter accumulate in a subset of wild-type imaginal discs in a manner that is geographically different. It's significant that the inversion mutant generally maintains these patterns.

We come to the conclusion that the promoters have separate and unique regulatory elements for spatial activation. Last but not least, we examined transcription in seven distinct dominant Antp mutants, all of which exhibit head transformation tissue to thoracic tissue.
