Answer:
The correct answer is -
Euglena - single-cell organism
Onion bulb - organ
Blood - tissue (connective tissue)
Explanation:
The level of organization of an organ, or organism could be cellular level, tissue level, the organ level, organ system, or a complete organism. These levels are formed by assembling the lower level of the organization.
Euglena is a single-cell eukaryotic organism found in freshwater. These organisms have a very simple level of an organism which is cellular level. The onion bulb is the organ of the onion plant composed of shortened, compressed, underground stems (tissue) that are an organ-level organization.
The blood is considered as connective tissue due to the blood cells present in the matrix called plasm thus, blood is connective tissue.
Yes and they also can choose to die
They form muscles, speed up chemical reactions, and perform many other cellular functions. Nucleic acids are organic compounds that include DNA and RNA. DNA contains genetic instructions for proteins, and RNA helps assemble the proteins.
Major morphological characteristics The presence of a bicondylar angle, or valgus knee; a more inferiorly placed foramen magnum; a reduced or non posable big toe; a higher arch on the foot; a more posterior orientation of the anterior portion of the iliac blade; a relatively larger femoral head diameter; an increased femoral neck length; and slightly larger and anterior posteriorly elongated femoral condyles.
<h3>
What is bipedalism?</h3>
Bipedalism refers to locomotion on two legs (e.g., walking, jogging, running, etc.). Although it is common to see animals standing or walking on two legs, only a few creatures use bipedalism as their primary mode of movement. Animals, such as chimps and gorillas, that temporarily acquire bipedalism in order to execute a specific role engage in a kind of movement known as facultative locomotion.
Bipedalism is not always the fastest or most efficient way to run or walk, but it offers certain benefits over certain specialized kinds of quadrupedalism. It's unclear why early hominins adopted bipedalism. Many ideas, however, contend that environmental selection forces drove the evolution of bipedalism.
