Emma and Anna are identical twins who were adopted by different families a few weeks after birth. Although genetically identical

, they grew up with different physical and psychological characteristics. For example, though both inherited a tendency to grow large, Anna was slim and athletic due to the active lifestyle practiced in her adoptive family. This variability can be explained by how:

Answer:

for each genotype, a range of phenotypes can be expressed

Explanation:

  • The genetic makeup of an organism is referred to as the genotype of the organism and is responsible for determining the characteristics of an organism.
  • The phenotype of the organism is the traits that are possessed by the organism by the expression of their genes however the phenotype of the organism is influenced by many factors.
  • The various factors that influence the phenotype of the organism are :

1. Genotype

2. The environment that the organism lives in.

3. Stochastic developmental events

<em>Therefore, even though Emma and Anna were identical twins having the same genotype they had variability in their phenotypes because environmental and developmental events also influence the phenotype of the organism. </em>

Which of these statements describes some aspect of facilitated diffusion?a.Facilitated diffusion is another name for osmosis.b.F
frosja888 [35]

Answer:

D

Explanation:

Facilitated diffusion is a form of passive transport hence no energy is required by the cell. This means that while the molecules are moving down a concentration gradient – line normal diffusion – the movement of the molecules needs to be facilitated (in this case by a transmembrane protein) either because the molecule is polar and can't pass through the hydrophobic region of the cell membrane, or the molecule is too big to passively pass through the small natural pores of the cell membrane.

Describe the steps in transcription that require complementary base pairing.
nalin [4]

Answer:

Explanation:

Transcription takes place in nucleus in the presence of the enzyme RNA polymerase.

During transcription, the code present in DNA gets transcribed into the code in mRNA.  (messenger RNA)

RNA even though is a single stranded shows base pairing.

The pre-mRNA gets created from the DNA.

DNA has two strands, one of these strands acts as coding and another non coding strand.

The DNA shows base pairing with AGTC.   [A-Adenine, G- Guanine, T-Thymine and C- Cytosine]

Whereas mRNA base pairing with AGUC.  [ U- Uracil ]

Here in mRNA, instead of thymine, uracil gets paired.

According to base pairing of coding strand/sense strand of DNA, complementary bases pairs in 5'---->3' direction in mRNA.

The mRNA created looks exactly like the non-coding strand/sense strand of DNA except instead of thymine, uracil gets replaced.

The pre-RNA undergoes splicing, capping and tailing to form mature mRNA.
