Introduction:
Living organisms vary from the single celled prokaryotic cells to the multicellular eukaryotic cells. Life or living organisms perform the basic functions of life that is respiration, locomotion, obtaining nutrition, response to stimulus, reproduction, growth and excretion. These functions distinguish them from non living entities.

Explanation of Solution
Correct answer:
The entire living organisms do not care for their offspring. Therefore, option (c) is correct.
Explanation for the correct answer:
The organisms, such as mammals, fishes, and birds care for their offspring until they get mature and are able to survive in nature. Some of the organisms do not care for their offspring. Instead, they leave them after the offspring’s are formed.
Option (c) is given as “care for their offspring”.
As, “all of the offspring are not cared by their living organisms”, is the right answer.
Hence, option (c) is correct.
Explanations for incorrect answers:
Option (a) is given as “organization”. The living organisms have a certain level of organization of
Option (b) is given as “acquisition of materials and energy”. The living organisms consume food and generate energy from their cellular activities. So, it is a wrong answer.
Option (d) is given as “reproduction”. All the living organisms reproduce and produce their offspring. Reproduction is an important key to the survival of organisms.
So, it is a wrong answer.
Option (e) is given as “responding to the environment”. All the living organisms respond to the external stimulus. So, it is a wrong answer.
Hence, options (a), (b), (d), and (e) are incorrect.
All the progeny are not are not taken care by their parental living organisms.

- When beta-lactamase was isolated from Staphylcoccus aureus and treated with a phosphorylating agent, only the active site, serine was phosphorylated. Additionally, the serine was found to constitute 0.35% (by weight) of this beta-lactamase enzyme. Using this, calculate the molecular weight of this enzyme and estimate the number of amino acids present in the polypeptide.arrow_forwardBased on your results from the Mannitol Salt Agar (MSA) media, which of your bacteria were mannitol fermenters and which were not mannitol fermenters?arrow_forwardhelp tutor pleasearrow_forward
- Q8. A researcher wants to study the effectiveness of a pill intended to reduce stomach heartburn in pregnant women. The researcher chooses randomly 400 women to participate in this experiment for 9 months of their pregnancy period. They all need to have the same diet. The researcher designs two groups of 200 participants: One group take the real medication intended to reduce heartburn, while the other group take placebo medication. In this study what are: Independent variable: Dependent variable: Control variable: Experimental group: " Control group: If the participants do not know who is consuming the real pills and who is consuming the sugar pills. This study is It happens that 40% of the participants do not find the treatment helpful and drop out after 6 months. The researcher throws out the data from subjects that drop out.
