Explanation:
The incorrect statement is: C) It transports mainly sugars and amino acids.
Xylem together with floem is a plant tissue involved in the transport of substances through the plant.
Xylem’s role is to transport water (sometimes and nutrients) from roots to stems and leaves and to provide support to the plant. Xylem consists of a specialized, water-conducting cells - tracheary elements (tracheids and vessel) which are long, narrow and hollow.
Answer:
Explanation:
Gregor Mendel showed his inheritance character in the garden pea plant. According to him, there are 2 alleles which are inheritable - dominant allele and recessive allele. The dominant allele is always dominant over the recessive one which is known as the complete dominance. When the offsprings have both recessive alleles it will show its character.
There are other characters present besides dominant and recessive. Such characters are known as Mendelian deviation as it does not obey Mendel's law of inheritance. e.g. codominance, incomplete dominance.
In codominance alleles, characters are blended and a new character has seen in the next generation. This new character is neither dominant not recessive, it is an intermediate character between the 2 characters.
e.g When the white and red flowers crossed pink flowers are formed along with red and white.
In the case of codominance, both alleles express their characters. Such phenotypic characters are known as codominance because both alleles are expressed in the offsprings.
e.g. When the red and white flower plants crossed the offspring flowers are red with white spots or the white with red spots.
Cells, the cell is the basic unit of life
The correct answer is option C, that is, the Operons afford the organism the opportunity to simultaneously monitor the transcription of multiple genes, whose products are active in the same process.
The genes, which correspond to a particular metabolic procedure are usually under the control of a single promoter in a bacteria. This is known as Operon that assists in monitoring the expression of genes taking part in the similar metabolic procedure.
