Answer:
The correct option is B. Prokaryotic
Explanation:
A prokaryotic cell can be defined as a cell which is unicellular and does not have any membrane-bound organelles present in it. Scientists claim that the earliest form of life was in the form of prokaryotic cells. The bacteria and archaea bacteria come under the category of prokaryotes.
The prokaryotic cell lack a nucleus. It's DNA material is present in a region called the nucleoid inside the cytoplasm of the cell.
Answer: Their supporting structure would be most likely the MUSCULOSKELETAL SYSTEM of the multicellular organisms.
Explanation:
The musculoskeletal system found in multicellular organisms are made up of structures which provides support, protection and allows for various movements. These structures include:
--> Muscles
--> Cartilage
--> Ligaments
--> Tendons and
--> Joints
Furthermore, Microtubules and microfilaments are the major components of cytoskeleton. They are the structures that gives a cell it's shape and helps organise it's parts. As described in the question, they are elongated structures that cross the cell, giving SUPPORT to the cell, and carries organelles and objects throughout the cell.
Therefore, since the Microfilaments and Microtubules provides support and shape at the cellular level it can be most likened to the musculoskeletal system of multicellular organisms which performs the same functions.
Answer:
When the body has excess water, thirst is suppressed. An interaction between the pituitary gland and the kidneys provides another mechanism. When the body is low in water, the pituitary gland secretes vasopressin (also called antidiuretic hormone) into the bloodstream.
Answer:
A) Effect of findings on other family members would be most important factor.
Explanation:
Genetic research is done on human DNA to know the genes and environmental factors associated with certain disease.
Institutional review board (IRB) is the regulatory authority to protect the rights of subjects invloved in a resaerch.
The genetic reaerches usually involve families, so the researcher subjects and the result of research is related to all subjects that cause increased information flow between subjects and effect their decision to partcipate independently in research. Also, if the research involve therapeutic studies special precautions would be taken to choose the subject
1) D because even if you rip all them out, the seeds of the plant are still in the ground
2) D because of the current, short-legged birds might get swept away
3) D because all of the other options would most likely not enforced.
