Answer:
The correct answer is:
The two layers of the plasma membrane are identical.
Explanation:
The plasma membrane is called a lipid bilayer because it is composed of two layers of cells and it makes the boundary of cell.
The other three statements are false because
Plasma membrane is semipermeable i.e it allows the transport of materials inside and outside the cell.
The proteins in the plasma membrane are integral proteins
The proteins in the plasma membrane are extensively folded and protruding from the membrane are in contact with inside and outside the cell.
Answer:
A: Cumulative recorder
Explanation:
B. F. Skinner was a psychologist, author, behaviorist and inventor of Operant conditioning chamber and Cumulative recorder. The purpose of cumulative recorder was to study the rate of operant conditioning. It is a process in which behavior of an organism is modified or an organism is conditioned to perform a specific behavior through giving punishment or reward.
For example: We teach a kid that he should not touch a hot stove because it will burn his hands, or we give him a box of candies to perform a specific task or behave in a certain way. Skinner used Cumulative recorder to find the effect of certain factors on behavior or response of an organism For example: the rate at which lever was pressed by a monkey to get bananas etc.
Hope it helps!
Answer:
Transcriptomics.
Explanation:
Transcriptomics may be defined as the field of biology that mainly deals with the study and collection of the mRNA molecules. Various techniques like DNA microarray and exon shuffling is used in transcriptomics.
Messenger RNA molecule are collected from the source that are produced by the cells. Transcriptomics helps the scientist to determine the similarities and differences in the gene expression pattern between the different cells.
Thus, the correct answer is option (2).
Of course the major needs of a plant is CHLOROPHYLL, because chlorophyll makes the plant green then SUNLIGHT, because the process cant work without energy. Then WATER and CARBON DIOXIDE.
