Answer:
mitochondria DNA (mtDNA) has maternal inheritance
chloroplast DNA (cpDNA) has paternal inheritance
Explanation:
DNA is deoxyribonucleic acid is the molecule responsible for encoding the genetics instructions used in the development and functioning of all known leaving organism.
in humans mitochondria DNA (mtDNA) has maternal inheritance and
chloroplast DNA (cpDNA) has paternal inheritance
Answer:
So when the first animals moved onto land, they had to trade their fins for limbs, and their gills for lungs, the better to adapt to their new terrestrial environment
Explanation:
During colonoscopy, a flexible Fiberoptic or video colonoscope is used to visualize, examine and photograph the large intestine including the anus, the rectum and the sigmoid, transverse and ascending colon. This procedure is most frequently used for cancer screening and for surveillance in patients with previous colon cancer or polyps. In addition, tissue biopsies can be obtained as needed and polyps can be removed and evaluated. Other uses of colonoscopy include the evaluation of patients with diarrhea of unknown cause, occult bleeding, or anemia; further study of abnormalities detected after a barium enema and diagnosis clarification and determination of the extent of inflammatory or other bowel disease. Colonoscopy is contraindicated if the patient has a suspected or documented colon perforation, acute severe diverticulitis or fulminant colitis.
The formula for the work done in emptying a tank is this:
W = ωyV
where
ω is the specific weight
y is the center of gravity
V is the volume of the liquid
The specific weight can be calculated using the formula
ω = ρg
where
ρ is the density
g is the acceleration due to gravity
Solving for ω
ω = 817.15 kg/m3 (9.81 m/s2)
ω = 8016.24 N/m3
The center of gravity of a completely filled cylindrical tank is just 1/2 of the height. So,
y = 3 cm
The volume of the kerosene is just the volume of tank. Using the formula for the volume of a cylinder
V = πr²h
V = π (3²) (6)
V = 54π m³
Therefore, the word done is
W = 8016.24 (6) (54π)
W = 8159538.47 J or
W = 8.16 MJ
