Answer:
Biology is the study of life. The word bio means life, ology means the study of.
Explanation:
I'm not sure if this is what you were looking for but this is the definition
Answer:
The correct answer will be option-A
Explanation:
The Mosses are the non-vascular plants that were developed from the aquatic plants and the ferns are the vascular plants which developed from the bryophytes.
Their life cycle shows alternation of generation and is largely dependent on the water for reproduction mainly fertilization or fusion of gametes.
The male gametes produced in these plant groups are haploid and are released in water which fuses in water with female gamete which is distinct from the higher plant groups gymnosperms and angiosperms where fertilization is mediated by mostly the wind or insects.
Thus, option-A is the correct answer.
Answer:
they are evolutionary neutral
Explanation:
Transposons are genetic mobile elements that move into the genome by means of cut-paste and copy-paste mechanisms. In consequence, transposons are known to produce mutations in the inserted genomic sequences.
Non-coding DNA regions have been generally assumed to be evolutionary neutral, it means that they might resist genetic polymorphisms (such as, for example, those caused by the insertion of transposon elements) and don't have direct effects on the phenotype of the organism. However, it is important to note that recent evidence supports the idea that noncoding sequences play important regulatory roles, thereby mutations in these genomic regions may have a deleterious effect on the organism.
The answer is Environmental issues.
Answer:
The human eye does not rotate, nor does it turn in search of sunlight to form a power source.
The human eye contracts its pupillary structure in order to collimate or select the rays of light that enter the eye, while the plant cannot make a selection or filtering of solar rays.
The human eye has three different types of cones and plants do not have the cone system.
Plants can absorb sunlight and rotate toward the beam up to 360 degrees while the human eye cannot.
Explanation:
The comparison between the human eye and this type of plants at the time of solar irradiation presents many differences, but the most important thing of all is that the human eye can regulate the entry of irradiation while the plants rotate towards where the ray of the sun but they cannot regulate how much sun they perceive by means of a filtering such as the contraction of the cornea
