O A. the body's nitrogen levels
B. the body's internal environment
OCthe body's external skin and hair
0
D. the body's support for movement
Answer:
B. the body's internal environment
Explanation:
Homeostasis is defined as the process of maintaining the internal environment of the body.
All the systems work together to maintain homeostasis. The nervous and endocrine systems are two important system that helps in maintaining homeostasis.
The nervous and endocrine systems are linked with hypothalamus that controls the internal environment of the body by releasing and inhibiting hormones. These hormones keep pH, temperature, and other internal conditions stable that support homeostasis.
Hence, the correct answer is "B. the body's internal environment".

Che healthy way to lose weight is to...
Drink a lot of water
O Take in slightly less calories than you use daily
O Eat no fats
O Eat no carbohydrates
1 point
Answer:
O Take in slightly less calories than you use daily
Explanation:
It has been shown that the healthiest diets to lose weight are those where individuals consume fewer calories than normal and simultaneously by taking care of consuming all essential nutrients in adequate quantities.
The essential nutrients to be consumed in a healthy diet include:
1- macronutrients, especially proteins (amino acids) to avoid muscle loss as well as normal metabolic functions, and fats, which are required to absorb some micronutrients (i.e., liposoluble vitamins)
2- micronutrients, which include vitamins (e.g., vitamin D, vitamin C, etc) and minerals (e.g., iron, calcium, etc).
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.

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.

Which kind of molecule provides building blocks for tissues, transports
other molecules, and helps regulate certain reactions in the human body?
A. carbohydrates
B.lipids
C. proteins
D. nucleic acids
Answer:
C : Proteins
Explanation:
(Can I get brainlest?)
Proteins are the molecules that provide building blocks for tissues, transports other molecules, and helps regulate certain reactions in the human body. The correct option is C.
What are proteins?A protein is a found naturally, extremely complex substance composed of amino acid residues linked together by peptide bonds.
Proteins are found in all living life forms and contain a variety of important biological compounds such as enzymes, hormones, and antibodies.
Proteins are massive complex molecules that perform numerous important functions in the body.
They are essential for the structure, function, and regulation of the body's tissues and organs and do the majority of the work in cells.
Proteins are molecules that serve as foundation for tissues, transport other molecules, and aid in the regulation of certain bodily reactions.
Thus, the correct option is C.

Protein synthesis consumes four high-energy phosphate bonds per added amino acid. Transcription consumes two high energy phosphate bonds per added nucleotide. Calculate how many protein molecules will have been made from an individual mRNA at the point when the energy cost of translation is equal to the energy cost of transcription. Assume that the nucleotides in the coding portion of the mRNA constitute 5% of the total that are transcribed.
Answer:
30 protein molecules per mRNA molecule
Explanation:
In this problem, it is necessary to have into account that the transcriptional process requires six (6) phosphate bonds to synthesize one (1) codon (i.e, each three nucleotides), and also discards 95% more energy to make mRNA, it means 19 times this amount of energy >> 6 x 19 = 114 bonds. In consequence, transcription requires 120 phosphate bonds (6 + 114 = 120), while translation requires four (4) phosphate bonds per codon. From this deduction, it is possible to find the number of protein molecules synthesized with regard to the energy cost of the translation process and the transcriptional process >>> 120 bonds (transcription) /4 bonds (translation) = 30 protein molecules.
