Cholesterol refers to a fat-like waxy substance, which is found in all the cells of the body. The body needs some cholesterol to produce hormones, substances that assist in digesting foods, and vitamin D. The body produces all the cholesterol it requires.
Cholesterol enhances the fluidity of the membrane, which otherwise comprises majorly the long-chain saturated fatty acids.
Cholesterol minimizes the fluidity of the membrane in the regions known as rafts that comprise huge concentrations of cholesterol and sphingolipids.
Answer:
25%
Explanation:
This cross involves a single gene coding for spot color in beta fish. Green allele is C while the blue allele is c. This gene exhibits co-dominance, hence, an heterozygote beta fish (Cc) i.e. combination of both alleles, will have both phenotypes expressed to form a green and blue spotted beta fish.
If two green and blue spotted beta fishes (Cc) are crossed, each beta fish will produce gametes with C and c alleles. Using these gametes in a punnet square, four possible offsprings with the following genotypes will be produced: CC, Cc, Cc and cc.
C c
C CC Cc
c Cc cc
Hence, the percentage of offsprings expected to be green (CC genotype) is 1 out of 4possible offsprings i.e. 1/4 × 100 = 25%
Answer:
2/3 of the progeny would be green
Explanation:
Lethal alleles means that their presence result in death of the organism
Assuming this Lethal allele is recessive --> a
This way, if there is AA or Aa the plant will survive, otherwise if there is aa the plant will not survive
Than, assuming AA is a progeny white and Aa is green
Aa x Aa
2/3 Aa - Green
1/3 - White
1/3 - plant will not survive
Crossing 2 green progeny with each other
Aa x Aa
2/3 - Green
I think the answer is false because blood flow can't prepare you for a potential encounter. Hope this helps ^_~
