The correct answer is (b) Organelles are not membrane- bound

The most characteristic feature of prokaryotes is that they lack membrane bound organelles. They have protoplasm, ribosomes, cytoplasm but none of them are membrane bound. All the organelles that are present inside the cell are dissolved in cytoplasm. They also lack nucleus.

Which of the following choices lists the ways that you can show intellectual honesty in scientific communication.
Alika [10]

Answer:

<em>The correct option is A) Do not let your personal beliefs interfere with the truth; do not omit facts even if they contradict your hypothesis or your goals; avoid bias; do not make up data; do not plagiarize; give credit to others if you cite their work.</em>

Explanation:

Ethics and scientific research go hand in hand. If intellectual honesty and ethics are not maintained during scientific research, then this field could raise many ethical concerns.

Modifications in results are strictly against ethics during scientific research. A scientist should never try to manipulate the results so that it supports their hypothesis. Cheating or stealing other peoples work is also not acceptable in the scientific world. A scientist should always be modest.
