Answer:
The invention of the microscope
Explanation:
<em>The invention of the microscope and the ability to see organisms that are otherwise invisible to the ordinary eye led to the establishment of Monera and Protista kingdoms</em>.
<u>Organisms in the Monera and Protista kingdom are microscopic and the invention of the microscope created and avenue for them to be studied extensively by scientists.</u>
Through their studies, taxonomists discovered that these microscopic organisms have characteristics that are neither of plants nor of animals.
<em>Some organisms were found to lack nucleus and membrane-bound organelles which is unlike plants and animals. Some were also found to posses most of the characteristics of animals except that they are unicellular.</em>
These led to the establishment of the Monera and Protista kingdoms respectively.
Answer:
Option B
Explanation:
Nitrogen fertilizer runoff into the farmlands results into Eutrophication which is a form of nutrient enrichment of the water body. Because of the nutrient enrichment, the productivity of the water increases and hence the oxygen level of the water reduces thereby degrading the quality of water and adversely affecting the aquatic life in the water body
Hence, option B is correct
Answer:
The main criteria of the five kingdom classification were cell structure, body organisation, mode of nutrition and reproduction, and phylogenetic relationships.
The Nervous system of the body consists of all the nerve cells. It is the body's "speedy" electrochemical communication system.
every neuron (nerve cell) has a long process known as 'axon' which is used to contact the next cell in the circuit. The receiving cell (another neuron) has small processes called 'dendrites' which are contacted by the axon. Now the neurons, like all other cells in the body, are enclosed by a selectively permeable cell membrane - which means it allows certain chemicals to pass through, while others are prevented from entering or leaving the cell
Polygenic inheritance result in a continuum of phenotypes because the genes that are involved can be considered to be co-dominant traits that fall into discrete categories are called continuous traits false.
<h3>What is Polygenic Inheritance?</h3>
A single inherited phenotypic trait that is governed by two or more separate genes is referred to as polygenic inheritance, often referred to as quantitative inheritance.
In a system that is distinct from Mendelian Genetics, wherein monogenic features are determined by the various alleles of a single gene, polygenetic traits may exhibit a variety of potential phenotypes, determined by a number of different genes and the interactions between them.
In contrast to Mendelian genetics, when one allele completely dominates or hides another, features generated by polygenic inheritance are not only the result of dominance and recessively. Instead, polygenic features show incomplete dominance, resulting in a combination of the phenotypes seen in the parents in the offspring.
