Euglena. It does photosynthesis like a plant, and moves around and eats like an animal.
Answer:
Light energy, Water, and Carbon Dioxide/Chlorophyll
Explanation:
Photosynthesis uses 12 water molecules, 6 Carbin Dioxide molecules and light energy so it can produce one glucose, six water and oxygen molecules. This can be expressed and represented by 12H2O + 6CO2 + light energy = C6H12O6 + 6H2O + 6O2
Vital to remember that the produced oxygen is from the original water molecules and not the carbon dioxide.
Answer:
Option-C
Explanation:
Scientists found a fossil of a fish with four limbs or legs. The fossil was estimated to be around 375 million years old.
The fossil showed the fins and scales of a fish but they also possess the bones of proto-wrist, shoulders and the elbow.
The presence of these bones can be a clue that the fish evolved the limbs to walk on the land and will later evolve into animals belonging to amphibians, reptiles and mammals. Therefore, the Tiktaalik is considered the missing link of how life evolved from water to land.
Thus, Option-C is correct.
I think the correct answer would be the last option. Monozygotic twins are identical, while dizygotic twins are fraternal. Identical twins involves developing from one zygote where it splits, forming two embryos so that the twins would have more or less the same characteristics. This type of twins can share the same amniotic sac depending on the time the fertilized egg is divided. On the other hand, fraternal twins developed from two eggs wherein they are being fertilized by two different sperm cells resulting to twins which has different characteristics. For this type, the two fertilized eggs would develop separate amniotic sacs.
