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.
I believe this is called the Atmosphere
Answer:
A.)are ectothermic organisms with variable body temperatures.
Explanation:
Invertebrates animal are animals that lack a backbone, Land invertebrates include insects,spiders, centipedes ,coelenterate, an arthropod, mollusc and the rest.
Ectotherms are also called called cold-blooded animal because their bl body temperature regulation is dependendent on external sources, such as sunlight or a heated rock surface. Some of the examples of ectotherms are fishes, amphibians, invertebratesand reptiles. The aquatic ectotherms body temperature is usually compare closely to the temperature of the surrounding water
Ectothermic species that lives in temperate regions usually experience rapid and potentially stressful changes in body temperature simply because of weather changes even among amphibians there is variation in their temperature
It is believed that naturally occurring periods of temperature variation negatively impact amphibian health.
Answer:
D. The Conus arteriosus of the amphibian heart receives blood from the right atrium and passes the blood on to the pulmonary circulation. This keeps oxygenated and nonoxygenated blood separate.
Explanation:
The conus arteriosus plays an important role in directing blood into the correct arterial arches in amphibian which keeps oxygenated and nonoxygenated blood separate from one another. The Conus arteriosus of the amphibian heart receives blood from the right atrium chamber of heart and passes the blood on to the pulmonary circulation which keeps oxygenated and nonoxygenated blood separate from each other and there is no need for partial ventricular septum.
I think it’s C. I know I’m right
