Answer:
The correct answer is option A.
Explanation:
Cellular organization is one of the characteristics of life that states that each living organism is made up cell or more than one cell, that is made up by organization of various components such as chemicals like micro molecule that form the macro molecule and these chemical level structural organization is formed together to make cells and this level of organization makes the tissue which is complex to cell but simpler to organ that is makeup of various together.
The makeup of organs is necessary as organs are the structural level that individuals facilitate the function and make up the organ system that is a complex system made up of organs that are similar in their function. The organism is the most complex of all levels.
Thus, the correct answer is option A.
Answer:
The correct answer is- founder effect
Explanation:
Founder effect occurs when a small number of individual isolates from the majority of the population by natural calamity or any other region. These isolated individuals show less genetic diversity than the larger population because they are less in numbers.
Therefore founder effect makes a small group of individuals isolate from a bigger population and make them occupy a different habitat. So a founder population can go on a newly developed island and start reproducing there.
A founder population over time converts into a new species because of reproductive isolation from the main population. So the evolution of life on the island of Hawaii should have been most strongly influenced by founder effect.
<span>the correct answer is B. the information that decides the characteristics of all organisms are contained in their nucleic acids. Nucleics acids are DNA and RNA. DNA have genes that code for proteins which are responsible for the structural and functional characteristics of organisms. DNA is transcribed into RNA and RNA is translated to proteins. Therefore information that is in these nucleic acids determines all the characteristics of organisms</span>
Rachel's behavior provides an example of Hypochondriasis. Hypochondriasis is a condition in which a person is inordinately worried about having a serious illness. It is often characterized by fears that minor bodily or mental symptoms may indicate a serious illness, constant self-examination and self-diagnosis, and a preoccupation with one's body.
The correct answer is option C, that is, the presence of the nuclear membrane.
Cyanobacteria is a phylum of bacteria that attain their energy via the process of photosynthesis, and are the only photosynthetic prokaryotes possessing the tendency to generate oxygen. As a prokaryote, they are devoid of the nuclear membrane.
Euglena refers to a single cell flagellate eukaryote. It comes under the class Euglenoidea. The species of Euglena are witnessed in salt water and in freshwater. Being a eukaryote, they possess nuclear membrane.
