No, biotic and abiotic factors are the environmental conditions that the organisms have to face to live in a specified environment. Abiotic factors are the physical and chemical conditions of an environment. For example : heat, salinity, pressure, light, wind, pH.Biotic factors are all the biological conditions of an environment for a specie/taxa. It can include prey and predator abundance, available food amount, available space, intra and interspecific competition... The development of organims is under the control of abiotic factors. Some are adapted to heat, cold etc ... The abiotic factors will define which organisms are able or not to live in a specified place. The living organisms will constitute the biotic factors, which define if and how can an organism live in a specified environment. So, the abiotic factors are controling the biotic factors of an environment.
Ans.
Incomplete dominance is defined as a pattern of inheritance, in which both of the alleles for a specific trait get expressed in offspring (neither allele is dominant or recessive).
It result in appearance of an intermediate, third phenotype or physical trait that shows combination of traits of both alleles.
For example, a cross between red colored and white colored flower of 4' O clock plants results in offspring plants with pink colored flowers
Thus, the correct options are :-
-Traits are neither recessive nor dominant.
-Offspring show an intermediate trait of alleles from the parents.
-Both alleles, one from each parent, get expressed in offspring.
-Incomplete dominance involves the interaction of two alleles.
Human blood groups are governed by three alleles. These are called I A ; I B ; I O .
I B shows the codominance
I O is recessive to both other alleles
Answer:
Immunoglobulin and Antibodies.
Explanation:
Have a nice day
The best answer would be:
A membrane bound nucleus
<u>Here is more about the question:</u>
There are three domains in the classification of organisms and they are Eubacteria, Archaea, and Eukarya. What makes Eukarya different from the other two is the presence of a nucleus in the cells. Among the remaining two, Archaea is more closely related to Eukarya than Eubacteria.
