What is body systems and their interaction?There are numerous parts to the human body. Every physical portion serves a distinct purpose. To better comprehend how the human body's components interact with one another and work together as a whole, scientists divide the body into systems. A group of bodily parts that cooperate to carry out a specific task is known as a body system.
For instance, the integumentary system, that shields the body from its surroundings, is made up of the skin, hair, and nails. Another instance of an organ that guards the body is the immune system.

Which statement best explains the ideas of phyletic gradualism and punctuated equilibrium?
A. Phyletic gradualism isn't supported by the fossil record, but punctuated equilibrium is
B. Phyletic gradualism states that many species evolve rapidly at specific points in time, and punctuated equilibrium states that speciation occurs constantly over time
C. Phyletic gradualism states that speciation occurs constantly over time, and punctuated equilibrium states that many species evolve rapidly at specific points in time
D. Phyletic gradualism is supported by the fossil record, but punctuated equilibrium isn't
A. Phyletic gradualism isn't supported by the fossil record, but punctuated equilibrium is
Punctuated equilibrium and phyletic gradualism are two opposing evolutionary tendencies that can be seen in the geological record. Species in punctuated equilibrium tend to demonstrate morphological stasis between rapid speciation episodes, whereas species in phyletic gradualism change more frequently. "Phyletic gradualism isn't supported by the fossil record, but punctuated equilibrium is," says the statement that best summarizes the ideas of phyletic gradualism and punctuated equilibrium.

The role of the RNA-induced silencing complex (RISC) in RNA interference is to cleave tRNAs to slow the rate of translation. disrupt gene expression by cleaving mRNAs that are complementary to the guide strand of the RNA duplex that was introduced. cleave the introduced RNA duplex. disrupt gene expression by interfering with mRNA export to the cytoplasm. create a passenger strand to bind to the mRNA and keep the mRNA from being translated.
Answer:
disrupt gene expression by cleaving mRNAs that are complementary to the guide strand of the RNA duplex that was introduced
Explanation:
The RNA-induced silencing complex (RISC) is a ribonucleoprotein complex composed of proteins that associate with regulatory small non-coding RNAs (sncRNAs) such as, for example, microRNAs (miRNAs) and small interfering RNAs (siRNAs) in order to regulate gene expression by the RNA interference (RNAi) pathway. These sncRNAs (around 18-30 nucleotides in length) are complementary or nearly complementary to messenger RNAs, thereby they can bind to target mRNA sequences in order to trigger RNAi via mRNA degradation, translational repression, etc. The core component of the RISC complex is an evolutionary conserved Argonaute (Ago) protein that cleaves target mRNAs.

What is the primary mechanism associated with the role of fluoride in prevention of dental caries? a. Fluoride increases calcium absorption, which increases crystal formation of teeth b. Fluoride increases salivation which aids in the removal of bacteria and the foods needed to sustain bacterial growth c. Decay is reduced due to the inhibitory effects of fluoride on growth of bacteria on the teeth d. Fluoride becomes incorporated into the crystalline structure of teeth, making them less susceptible to decay e. Decay is inhibited due to neutralization of organic acids produced by bacteria on the teeth
Answer:
d. Fluoride becomes incorporated into the crystalline structure of teeth, making them less susceptible to decay
Explanation:
Dental caries results when cariogenic (caries-causing) bacteria metabolize carbohydrates or sugars present in the mouth for their energy needs, producing organic acids as byproducts, thus lowering the pH of the plaque biofilm.
The hydroxyapatite of tooth enamel is composed mainly of phosphate ions (PO₄³⁻) and calcium ions (Ca⁺). Under normal conditions, there is a stable equilibrium between the calcium and phosphate ions in saliva and the crystalline hydroxyapatite. At low pH (acidic conditions), there is a shift in equilibrium resulting in the dissolution of hydroxyapatite from tooth enamel, a process known as demineralization. A reverse process called remineralization (the process of incorporation of minerals in tooth enamel) occurs when the saliva, acting as a buffer elevates pH. When equilibrium is shifted to favor continued demineralization, dental caries results.
However, when fluoride is present in saliva, fluorapatite, rather than hydroxyapatite, forms during the remineralization process as fluoride ions replace hydroxyl groups in the formation of the apatite crystal lattice.
Fluorapatite is less soluble than hydroxyapatite making it more resistant to demineralization, even under conditions of low pH. Thus, fluoride acts as an effective anticaries agent.
Sally, 9-year-old girl, just did an awesome backflip on her trampoline. Instead of landing in a similarly awesome manner, she miscalculated and landed on her neck. Sally stood up with pain in her neck and does not appear to be able to extend her left arm very well. An x-ray shows a fracture of her C6 vertebrae that is compressing down on her C7 vertebrae impacting the spinal nerve located between C6 and C7 vertebrae. Which spinal nerve did Sally likely injure
Answer:
The C7 spinal nerve
Explanation:
The C7 spinal nerve exits on each side through the intervertebral foramen between the C6 and C7 vertebrae. The C7 spinal nerve has both a sensory root which is composed of sensory fibers and a motor root. This nerve is required to control motor functions including shoulder movement (i.e., adduction, abduction and rotation). The C7 dermatome is a region of skin that receives sensory inputs from the C7 spinal nerve.
