Answer:
D. 1 BB : 2 Bb : 1 bb
Explanation:
This question involves a single gene coding for fur color in guinea pig. Black fur (B) is dominant over white fur (b). This means that, as stated in the question, if a black fur parent (BB) is crossed with a white fur parent (bb), a 100% heterozygous offspring (Bb) with black fur will result.
If two heterozygous guinea pigs are crossed i.e. Bb × Bb, the following gametes will be produced by each heterozygous parent:
Bb = B and b
Using these gametes in a punnet square (see attached image), offsprings with the following genotypic ratio will be produced:
1 BB : 2 Bb : 1 bb
BB and Bb = black fur guinea pigs
bb = white fur guinea pigs
Answer:
C. a decrease in phospholipid fatty acid side chain length and a decrease in side chain saturation
Explanation:
Temperature is a factor that has a huge impact on cell membrane structure, more precisely its fluidity. So, for example, if temperature increases, the cell membrane becomes more fluid because the fatty acid tails of the phospholipids become less rigid.
The lipid components of cellular membranes often include phospholipids and cholesterol. Phospholipids is made up of glycerol, fatty acids, phosphate and organic derivatives such phospho inositol and choline. Cholesterol is the component of the membrane lipid which determine the fluidity of the memebrane; it also participates in membrane singalling system.
Answer:
Because Lumbricina ( Earthworm ) Is a living, breathing, animal
Explanation:
Answer:
The streaks made by the limonite are yellow, and the streaks made by Mary and Jim’s sample are brown. Therefore, they are not the same mineral. The rock is not made of limonite.
