Answer:
A few obstacles would make it tough to accomplish this objective. In the first place, the polypeptide backbone is characteristically polar. Hardly any proteins would be dissolvable in a non-polar hydrocarbon. Moreover, to keep up the dissolvability of this protein, most of its amino acids would need to contain hydrophobic or non-polar R groups.
Then again, its charged or polar R groups would need to connect with one another or be covered in the core of the protein away from the hydrocarbon solvent. This would put noteworthy requirements on both the idea of the R groups and the structure of the protein that could take part in substrate recognition or catalysis. By and large, this is certainly not a reasonable objective.
Answer: (A) a membrane‑bound organelle with stacks of thylakoid discs called grana.
(E) the main site of photosynthesis in a plant cell.
Explanation:
The plant chloroplast is a large organelle, it is bounded by a double membrane like structure that is chloroplast envelop.
The chloroplast consists of chlorophyll pigment which traps the light energy from sun and converts it into chemical energy in the form of ATP. Thus the chloroplast is the main site for photosynthesis. Including the inner and outer membrane structure it also posses the third internal membrane structure which is called as the thylakoid membrane. The thylakoid membrane forms the network of flat discs which are called as thylakoids, the thylakoids are arranged in stacks which are called as grana.
The thylakoid membrane is the center point for the synthesis of ATP through a chemiosmotic process.
To first dive into your question, here are some vocabulary terms that I will be using and will be helpful to you as well.
- Homozygous dominant (BB): <em>Is not affected by cystic fibrosis</em>.
- Homozygous recessive (bb):<em> Is affected by cystic fibrosis</em>.
- Heterozygous (Bb):<em> A carrier for cystic fibrosis</em>.
- Phenotype (Ex: Having cystic fibrosis): <em>The appearance of an allele pair</em>.
- Genotype (Ex: bb): <em>The genetic makeup of an allele pair</em>.
We know that if both of the parents are phenotypically normal, there is no way that they can be homozygous recessive (bb), or have cystic fibrosis. We also know that since they have a child with this disease, they can't be homozygous dominant (BB) either. This means that <u>both parents have to be carriers (Bb)</u> in order for them to have a child with cystic fibrosis.
Below I have attached a Punnett square with both of the heterozygous parents.
<em>Each child they have will have a </em><u><em>1/4</em></u><em> or </em><u><em>25%</em></u><em> chance of having cystic fibrosis.</em>
Because a thermal plant radiates and generates energy itself with the decreasing number of fossil fuels we have left because of how much we use them a source like this can help give off energy and reduce our carbon foot print
