Answer:
i want to know the answer
Explanation:
Answer:
The correct answer is statement c.
Explanation:
The procedure of the development of bones from hyaline cartilage is known as endochondral ossification. Endochondral ossification transforms hyaline cartilage into true bones, that is, hyaline cartilage functions as a template for the formation of bones. All the bones of the body, except for the mandible, flat bones of the skull, and clavicles are produced via endochondral ossification.
A certain bacterial mRNA is known to represent only one gene and to contain about 800 nucleotides. If you assume that the average amino acid residue contributes 110 to the peptide molecular weight, the largest polypeptide that this mRNA could code for would have a molecular weight of about _______.
A) 800.
B) 5,000.
C) 30,000.
D) 80,000.
E) An upper limit cannot be determined from the data given
Answer:
c. 30,000
Explanation:
The gene has a total of 800 nucleotides and would be transcribed into an mRNA having about 800 nucleotides. The nucleotides of mRNA are read in the form of genetic triplets. This means that the mRNA with 800 nucleotides would have about 800/3= 266.66 or 266 genetic codes. This mRNA would be translated into a polypeptide chain having around 266 amino acids.
One amino acid contributes 110 to the molecular weight. The total molecular weight of the largest possible polypeptide that can be encoded by the said gene would b 266 x 110= 29260 (around 30,000).
Answer:
Fundus.
Explanation:
The fundus or ophthalmoscopy consists of viewing the retina and the optic disc through the pupil and the transparent media of the eyeball (cornea, aqueous humor, crystalline humor, and vitreous humor) including the optic disc, retinal vessels, macular area and fundus as a whole. It is an important component of the clinical evaluation of many diseases and is the only location where the vascular bed can be observed in vivo in a bloodless manner. The direct ophthalmoscope is available to perform it in Primary Care (PC) consultations and in other specialties, this is an optical instrument that directs light directly onto the retina through a mirror that reflects a ray from the light source. This mirror has a central hole that allows the observer to view the illuminated retina. The major retinal vessels are examined and tracked distally as far as possible in each of the four quadrants (superior, inferior, temporal, and nasal). The color, tortuosity, and caliber of the vessels are examined. The posterior pole is between the temporal vascular arches, measures 5-6 mm, and is where most of the lesions in diabetic retinopathy are located, such as microaneurysms, hemorrhages or exudates.
Answer:The intensity of sunlight decreases rapidly with depth. The depth of the water not only affects the colors of light that are noticeable underwater, it also affects the intensity, or amount of light. Within the first 10 m, water absorbs more than 50 percent of the visible light energy
