Answer:
Chloroplasts are the ’solar energy plants’ of a cell – they convert light energy into chemical energy
This chemical energy may be either ATP (light dependent) or organic compounds (light independent)
Only photosynthetic tissue possess chloroplasts (e.g. is present in leaves but not roots of plants)
Chloroplasts are thought to have once been independent prokaryotes that were internalised by eukaryotes via endosymbiosis
They have a double membrane structure (due to vesicular coating as part of the endocytotic process)
They have their own DNA (circular and naked) and ribosomes (70S)
Their metabolic processes are susceptible to certain antibiotics
The structure of the chloroplast is adapted to the function it performs:
Thylakoids – flattened discs have a small internal volume to maximise hydrogen gradient upon proton accumulation
Grana – thylakoids are arranged into stacks to increase SA:Vol ratio of the thylakoid membrane
Photosystems – pigments organised into photosystems in thylakoid membrane to maximise light absorption
Stroma – central cavity that contains appropriate enzymes and a suitable pH for the Calvin cycle to occur
Lamellae – connects and separates thylakoid stacks (grana), maximising photosynthetic efficiency

THE OVERALL UNBALANCED:
C6H12O2 + O2 -> CO2 + H2O + ENERGY
THE BALANCED:
C6H12O6 + 6O2 -> 6CO2 + 6H2O + ENERGY
IN WORDS IT WOULD BE:
Glucose + oxygen -> carbon dioxide + water + energy
Answer:Scientific research is the investigation or examination performed by applying systematic scientific methods to obtain, analyze, and interpret the data. The sample size of the population plays a crucial role in research. The phrase that limits the accuracy of the research is:Option A: A sample size of 300 peopleScientific studies are advantageous when:It is conducted on large population size. The number of individual users in the research is used to calculate the set of statistics.The large sample size allows the scientist to better understand and average the values of data. The large population size also helps in neglecting the errors, which can be frequent on the small population size. The maximum size of the population is usually 10percent of the total population. It can be calculated as the total population of 200,000, the 10% will be 20,000. Thus, for the scientific study conducted by Marcus, the sample size of 300 people will limit the accuracy of the experiment.
Explanation:
First, let's define the alleles:
(Dominant) allele for unattached earlobes is E
Allele for attached earlobs is e
(Dominant) allele for dark hair is H
Allele for light hair is h
Heterozygous would mean that for both sets of alleles, they will be EeHh.
Now for a Punnett Square:
EH Eh eH eh
EH EEHH EEHh EeHH EeHh
Eh EEHh EEhh EeHh Eehh
eH EeHH EeHh eeHH eeHh
eh EeHh Eehh eeHh eehh
These are all the possibilities for the parents' offspring. Since the square is 4x4, then the number of genotypes is <u>16</u>.
<u>Now for the probabilities of each genotype</u> (the amount of times a certain genotype appears divided by the total number of genotypes):
EEHH: 
EEHh: 
EEhh:
EeHH:
EeHh: 
Eehh:
eeHH:
eeHh:
eehh:
(If you ever want to check if your probabilities are off, just add them together and they should add up to the total!)
Hope this helps! :)
