The function of the integumentary system includes all but not innervation of skeletal muscle.
The human body is a complicated machine that has numerous moving corridors. The colorful functions of the body are divided into eleven body systems called the integumentary, respiratory, digestive, lymphatic, cardiovascular, reproductive, urinary, nervous, endocrine, skeletal, and muscular. These systems represent a group of tissues and organs that perform specific functions in the body but some tissues and organs support further than one system.
The integumentary system functions as the first position of hedge protection for the body. The other functions of this system include regulation of body temperature, excretion through sweating, Vitamin D conflation (immersion), the discovery of stimulants (sensation), and elimination of poisons (stashing/ secretion).

HeEeLllpp 8.Carbon atoms are important for all of the following reasons except
The one exception to the reasons why carbon atoms are significant is (d) their ability to form ionic bonds.
The periodic element with atomic number 6 is carbon. On Earth, it occurs the most frequently. Stable covalent bonds are created between carbon atoms and other elements. Catenation is the ability of carbon to make four covalent connections with itself.
The non-covalent bonds that are less strong than covalent bonds are ionic bonds. Instead of neutral atoms, two charged atoms join together to form this bond. This bond typically has large variations in electronegativity between the atoms. The atoms are changed over to more electronegative atoms in this place.

The deforestation of tropical rainforests is a serious concern because the biome is a major storehouse for biodiversity, an important reservoir of carbon, and a major producer of atmospheric oxygen.
Tropical rainforests are those that develop in areas with a tropical rainforest climate, which means there is never a dry season and all months have an average precipitation of at least 60 mm. These ecosystems are also referred to as lowland equatorial evergreen rainforests.
The tropical rainforest biome is characterized by very high annual rainfall, high average temperatures, nutrient-poor soil, and high levels of biodiversity (species richness). The tropics receive almost direct sunlight, which produces strong solar energy that keeps temperatures between 70° and 85°F (21° to 30°C) high.

hypoxia can cause apoptosis by increasing excitotoxicity in the cell via glutamate. what downstream cellular effects would this have?
A lethal influx of extracellular calcium results from excitotoxicity, which happens when neurons are exposed to high levels of glutamate.
This results in a persistent activation of the N-methyl-d-aspartate acid (NMDA), -amino-3-hydroxy-5-methylisoxazole propionic acid (AMPA), and voltage-gated calcium channels.
As cellular energy stores and Na+ gradients decline during hypoxia-ischemia, increased glutamate release and defective glutamate uptake create a toxic accumulation of extracellular glutamate, which causes glutamate receptors to become overstimulated and ultimately results in neuronal cell death.
Does excitotoxicity cause cell death?
Since excitotoxic stimulation of neurons may result in increased NO synthesis and exposure of neurons to NO may result in the release of excitotoxins, these two pathogenic mechanisms are intimately related. Excitotoxic neuronal death can be either apoptotic or necrotic, depending on the experimental conditions and cell type.

In the gal gene system, which protein binds to the activation domain of the activator protein, ultimately blocking transcription in the absence of galactose?.
In the gal gene system , Gal80 protein binds to the activation domain of the activator peotein, ultimately blocking transcription in the absence of galactose.
The transcriptional activator Saccharomyces cerevisiae GAL4 is negatively regulated by the Saccharomyces cerevisiae GAL80 gene. Although GAL4 can still connect to the UAS sequence after being bound by a GAL80 dimer, it can no longer induce transcription.
The GAL4 gene's interaction with GAL80 depends on the 30 amino acids at its C-terminus.
Thus, by combining a transgene or modified endogenous locus encoding a GAL4-based "driver" with a second transgene or modified endogenous locus in which the target gene of interest is located downstream of UAS sequences, GAL80 can be used to further refine the expression pattern of a gene of interest expressed using the UAS-GAL4 binary expression system.

during the elongation stage of translation, the ribosome translocates relative to the mrna and the trnas. this step requires the elongation factor
During the elongation stage of translation, the ribosome translocates relative to the mRNA and the tRNAs. this step requires the elongation factor EF-G and hydrolysis of GTP.
The tRNA with the proper corresponding anticodon will pair with the relevant mRNA codon during the translation's elongation phase. Methionine from the first tRNA joins with the second amino acid from the second tRNA to form a peptide bond, the kind of bond that binds amino acids together.
After then, the ribosome shifts downward, moving in the 5' 3' direction, creating room for a new tRNA to link with its corresponding codon and produce a new peptide bond. The ribosome continues this process by traveling down the mRNA strand and lengthening its amino acid chain as it does so.
