Answer:
Genes aren't eradicated from natural selection, but the chances of getting the phenotypes (the physical attributes of an organism based on the genes) go down as the organisms with those phenotypes die out.
Explanation:
Recessive genes are still present in, for example, a heterozygous genotype. but since there is a dominant, it covers the recessive gene and the phenotype won't have anything to do with the recessive gene (unless we are talking about incomplete or codominance).
Answer:
The correct answer is- bioremediation and acting as a carbon sink
Explanation:
Plants play various roles in affecting the environment. Plants prevent soil erosion, pulling carbon from the atmosphere by photosynthesis incorporating or releasing oxygen by cellular respiration, acts as pollution indicator, decreases soil toxicity, provides habitat and niche and many more to balance ecosystem and improve the environment.
Plants to help in cleaning the environment can be played by these two ways:
1. bioremediation in pants or phytoremediation is the process in which the roots system of plants uses synergistic action for the growth of microorganisms and removal of toxic substances from the soil.
2. plants also play the role as a carbon sink due to the ability to absorbs a huge amount of carbon from the environment and use it to produce food and energy and releases oxygen in this process.
They answer is phytochrome, which responds to light in a critical darkness period which tells the plant when to flower
Bryophytes never form xylem tissue, the special lignin- containing, water-conducting tissue that is found in the sporophytes of all vascular plants.
