This seems to be the best answer: C. The data does not take into account underground growth and the actual area of fungus spread may be larger, so the original conclusion of the experiment is not accurate.
Sperm must be deposited and transported to the site of fertilization. Ovulation must occur and the egg must be "picked up" by the tube. Union between the sperm and egg must result. The embryo must implant and begin to grow in the uterus.
Answer:
The tilt of earth's rotation axis stays the same as it orbits the sun.
Explanation:
The axis of the Earth is an imaginary line around which the Earth is known to orbit. The axis of the earth is known to tilt at an angle of 66 and a half degrees. The tilt of the axis of the Earth remains the same and it does nor change as the earth orbits around the sun. The orbiting of the Earth around its axis causes day and night to occur on the planet Earth. The rotation of the Earth around its axis is slowing with time.
Answer:
The positive charge of the histone proteins get reduced due to the process of histone acetylation, thus making the wrapping of DNA around the histones less tightened. The loose connected DNA afterward associates with the transcription factors for the articulation of the genes situated in that area.
Generally, when there is no requirement of gene anymore, the acetyl groups from the histones get withdrawn by the activity of histone deacetylase enzyme (HDAC9) that makes the DNA tightly wrapped and inaccessible again. In case, when less expression of histone deacetylase enzyme occurs, the process of deacetylation fails to take place. This indicates that within an immune cell, at the time of infection, the inflammatory gene, which was made available does not get re-wrapped firmly around the histones.
The correct answer is option D, that is, mitochondria and chloroplasts.
Mitochondria and chloroplasts are the two organelles witnessed in the eukaryotic cells. The majority of eukaryotic cells exhibit mitochondria, while chloroplasts are only found in plants.
Apart from the nucleus, mitochondria and chloroplasts are the only organelles that comprise their own genetic material. They both possess their own DNA, and therefore, both the organelles utilize their own DNA to generate various enzymes and proteins needed for their normal functioning.
