Answer:
catabolite activator protein (CAP)
Explanation:
Catabolite activator protein (CAP) is a homodimeric transcriptional activator required for transcription initiation of catabolite-sensitive genes in <em>Escherichia coli</em>. CAP contains a ligand-binding domain at its N-terminus and a DNA-binding domain at its C-terminus. CAP activates transcription by binding at target DNA sites on promoter sequences, thereby enhancing the ability of the RNA polymerase to bind and initiate transcription. CAP binds cyclic AMP (cAMP) to increase CAP’s affinity to DNA and thus activates the transcription of genes for catabolism, such as the lactose (lac) operon genes (the lac operon is a set of genes that encode for enzymes taking part in lactose metabolism).
Answer:
Explanation: In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers. A concentration gradient exists for these molecules, so they have the potential to diffuse into or out of, the cell by moving down it.
Explanation:
The answer is B.
That's : Red blood cells are flat and indented so they can carry the greatest possible amount of oxygen.
The answer you chose is incorrect, because it is the white blood cells which destroys infection.
Answer:
Although figure is not attached in the answer but as per past knowledge it can be answered.
What is the phenotype of offspring from a round yellow seed plant and a wrinkled green seed plant?
There are two parents, one is wrinkled green and the other is round yellow. For wrinkled green, the genotype will definitely be rryy because both are recessive traits. For round yellow seed parents, the genotype can be either RRYY, or RrYy. Let's cross them one by one.
Condition 1:
rryy x RrYy
Gametes: ry RY or Ry or rY or ry
Offspring: RrYy : Rryy: rrYy: rryy
1/4 : 1/4 : 1/4: 1/4
So, in this situation the phenotype of 1/4 will be round yellow (RrYy), 1/4 will be wrinkled yellow (rrYy),1/4 will be round green (Rryy), 1/4 will be wrinkled green (rryy).You can see the punnet square in figure for better understanding.
Condition 2:
rryy x RRYY
Gametes: ry RY
Offspring : RrYy
In this scenario, all of the offspirng will have the genotype of RrYy and the phenotype will be round and yellow.You can see the punnet square in figure for better understanding.
Hope it helps! :)
The individual is likely using two-person psychology. A two-person psychology likely involved with understanding psychoanalytic concepts in which it also considered the treatment of an individual as a way of interacting between two individuals that are involved. The answer is two-person psychology.
