The statement given above is FALSE.
In the United States, National labour union formation began earnestly after the civil war but most of these unions become non functional as a result of lack of organization, discords over union goals, lack of effective leadership, opposition from employers and the government. In the past decades, the number of employees that are members of unions have significantly decrease, this is especially true for private companies.

<span>This statement is false. Labor unions have gotten smaller when compared to their peak membership times in the 1950s. They do remain a big factor when it comes to politics in the United States, they are mobilized well and through dues and coalitions can organize around important issues like trade policy, immigrant rights, living wage campaigns, and health care.</span>

Explain the advantages to a plant of having its cell membranes surrounded by cell walls

QveST [7]

Plant cell walls are rigid membranes on the outermost part of the cell. The cell wall provides a structured shape for the cell, helping the cell retain its form and shape. The cell wall also controls the rate of replication, allowing plant cells to replicate at a much slower rate than animal cells.

What are the common promoter elements found in eukaryotic genes, and how are they different from enhancer elements?

V125BC [204]

Answer:

In eukaryotic cells you find core and proximal promoters.

Promotors are specific DNA sequences where transcription factors (proteins) and RNA polymerase binds to initiate transcription. Promotors are located upstream the coding sequence

Core promoters are where RNA polymersae binds and proximal promoters are where transcription factors bind.

Enhancer elements are DNA sequences where transcription factors (proteins) bind to increase the rate of expresion of an specific gene. Enhancers can be located either upstream, downstream or thousands of nucleotids away from the of the coding region.

Explanation:

Promoters and enhancer are key elements for controling gene regulation. Transcription begins when chromatin rearranges from a condensed state to a accesible state, this allow to transcrition factors and RNA polymerase to bind specif DNA sequences (promotors). Proteins bind to enhancers , this complex develops a DNA loop, so that the protein that is bound to the enhancer interacts with the RNA polymersase. When this interaction is made, the activity of the RNA polymerase is increased.

Answer:

The correct answer is : state - dependent memory.

Explanation:

State dependent memories are recollections of memories that are set off or enhanced or increased by an individual's present mind-set in view of the relationship to memories framed when you were in a comparative state.

For example, pleasant memories are all the more effectively or strongly recalled when one is feeling happy and the equivalent goes for negative thoughts and sadness or outrage towards something. In this case Joe having more negative thoughts in response of depression or negative thoughts.

Answer:

The correct answer is -

A: Prophase (top left)

B: Cytokinesis (top middle)

C :Interphase (top right)

D :Telophase (bottom left)

E: Metaphase (bottom middle)

F: Anaphase (bottom right)

Explanation:

A. prophse - the first stage of mitosis, in this pahse the chromatin which is DNA and proteins, condenses in nucleus.

B. Cytokinesis - It is the physical sepration or dividion of cytoplasm of the parental cell.

C. Interphase - This phase have no change in cell except its size as it grows and enlarges itself.

D. Telophase - formation of a nuclear membrane around chromosome set to separate the genetic material from the cytoplasm.

E. Metaphase - visible chromosomes, removal of nucleus and chromosomes present in cytoplasm.

F. Anaphase - replicated chromosomes are separated and move towards opposite poles.
