Answer:(i)The most common way for a dead organism to avoid decomposition: The body could be buried in a sandstorm.
(ii)Dry and barren places have high erosion that reveals fossils. Dry and barren places are comfortable for heavy phyiscal labor.
(iii)Radiometric dating methods
(iv)In a quadrupedal pelvis, the ilium lies lateral to and parallel to the vertebral column and the ischium extends dorsally. ... In a bipedal pelvis, the ilium is shorter, wider and expanded front-to-back. Where the ilium articulates with the sacrum is wider, providing greater stability and support.
(v)Lucy has a more humanoid pelvis because she was a hominin.

Answer:
A) 300
B) 3:1
C) 9 long yellow : 3 long green : 3 short yellow : 1 short green
Explanation:
Long stems (L_) are dominant to short stems (ll)
Yellow seeds (Y_) are dominant to green seeds (yy)
We interbred pea plants with long stems and yellow seeds (L_Y_), but they had a short green parent (llyy) that could have only produced <em>ly</em> gametes, so our plants are heterozygous <em>LlYy</em>.
C) We interbred them LlYy x LlYy. If the two genes are unlinked, this is a typical dihybrid cross and from Mendel's law of independent assortment we know that the offspring will have the following phenotypic ratios:
- 9/16 L_Y_ (Long, yellow)
- 3/16 L_yy (Long, green)
- 3/16 llY_ (short, yellow)
- 1/16 llyy (short, green)
A) 3/16 × 1600 = 300 plants will be long and green.
B)
9/16 + 3/16 = 12/16= 3/4 plants will be yellow;
3/16 + 1/16 = 4/16= 1/4 plants will be green.
The ratio will be 3 yellow : 1 green
Answer:
Niacin (Ans. A)
Explanation:
Nicotinamide adenine dinucleotide (NAD) is known as important cofactor which help in carrying electrons from one reaction to another reaction in the cellular respiration process.
Cells are able to restore performed compounds which are containing a pyrimidine base precursor vitamin for the synthesis of NAD: nicotinamide, nicotinic acid, and nicotinamide riboside.
These elements are taken up from the diet whos containing vitamin B3. Nicotinamide, and nicotinamide riboside both can be absorbed from the gut. Niacin or vitamin B3 also produced within cells with the help of cellular digestion of NAD+.
Located on the basilar membrane are(is) the <u>organ of Corti</u><u> </u>containing hair cell sensory receptors for the sense of hearing.
The organ of Corti is also called basilar papilla which is a complex form of neuroepithelium composed of hair cells sensory receptors and supporting cells. In addition to these sensory and supporting cells, the organ of Corti also consists of a tectorial membrane. Endolymph which is a potassium-rich fluid surrounds the organ of Corti. The organs known as scala tympani and scala vestibule are present under and above the basilar papilla respectively.
The function of the organ of Corti is to generate electrical signals based on the sounds and transmit these signals to the brainstem through the passage of auditory nerves.
