Answer:
Mikroalga adalah alga mikroskopik, biasanya terdapat di sistem air tawar dan laut. Mereka adalah spesies uniselular yang wujud secara individu, atau dalam rantai atau kumpulan. Bergantung pada spesies, ukurannya boleh berkisar antara beberapa mikrometer (µm) hingga beberapa ratus mikrometer.
Explanation:
Answer: Carbon dioxide
Explanation:
The chemolithophs are the prokaryotes which uses inorganic matter in order to make organic materials for the other processes.
These organism get energy by the oxidation of the inorganic compounds. The organism such as human beings breaks down the organic compounds in order to get energy and nutritional building block.
The macro molecule used by the organism is carbon dioxide.
Answer:
Limit their fast food intake.
Explanation:
Fast food places have a lot of salt in their food because adding salt, which is a preservative, allows them to store the food supplies longer and save money.
Food, water, shelter, and warmth represent <u>physiological</u> needs in Maslow’s hierarchy of needs.
Abraham Maslow proposed and developed a theory in human development psychology titled "A theory of human motivation" in 1943.
Maslow's Hierarchy of Needs can be defined as a pyramid model which typically represents the fundamental (basic) needs of an individual, that are essential and required to be met before he or she can achieve complete growth, development and self-actualization.
The five (5) levels of Maslow's Hierarchy of Needs in a chronological order are;
According to Abraham Maslow the psychological needs comprises:
I. Food.
II. Water.
III. Shelter.
IV. Warmth.

Answer:
This is an incomplete question.
Below should be the complete one with options:
A researcher introduces a signal produced by bacteria to eukaryotic cells that she is culturing in the laboratory. Remarkably, she notices that this signal results in an increase in eukaryotic gene expression. How is this possible?
A.This gene expression is likely independent of the presence of the prokaryotic signal.
B.The signal is either similar in structure to a ligand used by eukaryotes, or this signaling pathway is utilized by both prokaryotes and eukaryotes.
C.This signaling pathway might actually be utilized by both prokaryotes and eukaryotes.
D.This signal is likely similar in structure to ligands utilized by eukaryotic cells.
E.This prokaryotic signal likely travels directly into eukaryotic cells and acts as a transcription factor.
THE CORRECT ANSWER IS B
B.The signal is either similar in structure to a ligand used by eukaryotes, or this signaling pathway is utilized by both prokaryotes and eukaryotes.
