The answer is a half-filled circle.
In the pedigree charts, squares present males and circles present females. If a female is healthy, the circle is empty (white). If a female is affected with a trait, the circle is filled-in (usually black). However, if a female is a carrier of a disease, which means that one allele is dominant and one is recessive, then the circle is half-filled.
Answer:
Option-D
Explanation:
Plants are the organisms present on the Earth which can be easily marked with their green color. The green color is due to the presence of the chloroplast which encompasses the chlorophyll pigment.
The chlorophyll pigment has the ability to capture the sunlight energy which initiates the process of photosynthesis. The photosynthesis process utilizes Carbon dioxide gas and water to form glucose molecules.
The glucose molecule is then transported to the other parts of the plants like stem and roots where photosynthesis is absent and to obtain the energy, plant perform cellular respiration. The cellular respiration requires oxygen gas which acts as an electron acceptor molecule.
Thus, Option-D is correct.
The moment sun will die planet Earth will leave it's orbit exactly 8 minutes and 42 seconds later.
And then will go on wondering forever in the cold surrounding of universe till it's not captured into another stellar system which seems to be a little hard to imagine.
The answer should be Environmental Protection Agency, because its the agency US federal government into mission of protecting environmental health or human health
Hope this helps.
