Answer:
Photosynthetic lamellae
Explanation:
The cyanobacteria were the first successful photosynthetic cells present on the Earth which were able to convert the light energy into the chemical energy.
The endosymbiosis theory suggested that these cyanobacteria were engulfed by the eukaryotes and the cyanobacteria get transformed into the chloroplast.
The region of the chloroplast that was formed in the cyanobacteria before the endosymbiosis happened was the photosynthetic lamellae which contained the chlorophyll molecule and thus is the correct answer.
Thus, Photosynthetic lamellae are the correct answer.
Answer:
your heart rate goes up explaining why the blood is traveling quicker. this causes you to breath faster meaning bring more oxygen to the blood in your lungs faster. your blood pressure also goes up from the increase in heart rate.
The area namely Tundra receives least amount of precipitation, i.e., option C.
<h3>What is a biome?</h3>
A distinctive biogeographical unit built by a biological community in response to a shared regional environment. Biomes can exist on multiple continents.
A biome is a broader phrase than habitat and can include a wide range of habitats.
The area among the biomes, namely Tundra receives least amount of precipitation.
Thus, the correct option is C.

False, a lipid bilayer is a MOSTLY apolar cell structure,which means polar molecules can't easily go through it
Answer:
Mutation, Gene flow/Migration/Immigration of gene and Recombination
Explanation:
For any species there are majorly three sources of genetic variations –
a) Mutation – This leads to change in the genetic code with in the DNA of an organism. Sometimes mutation does not produce any effect on the organism. Mutation can produce both positive and negative impact. Its effect is observed in long run as its rate is slow.
b) Recombination – When an organism undergoes sex, his/her genes recombine with the genes of mating partner. The rate of recombination is faster than the rate of mutation
c) Gene flow /Migration/Immigration of gene – In this gene travel from one set of population to the other. The frequency of gene in the mixed population lies between the original population gene frequency and the migrated or donor population gene frequency
