Prokaryotic cell

A prokaryotic cell is one that lacks a genuine nucleus as well as membrane-bound organelles.
Prokaryotes are organisms that have prokaryotic cells and are usually single-celled microbes.
The only structure or component that a virus and a cell share in common, according to the information in the Venn diagram, is nucleic acid. The virus is devoid of all other cellular features, and it is unable to exist, prosper, or replicate on its own.
A virus and a prokaryotic cell have Nucleic acid in common.

Viruses are not cells at all, so they are neither prokaryotes nor eukaryotes. Viruses contain DNA but not much else. They lack the other parts shared by all cells, including a plasma membrane, cytoplasm, and ribosomes

There are four steps in bacterial conjugation. The second step is missing in this list.1. Special sex pilus connects two cells.
2.
3. Each cell makes a complementary DNA strand.
4. The cells separate.
Which is the missing step for the process of conjugation described?

Answers

Answer:

2. The Fusion of cell membranes and transfer of single strand of plasmid DNA of donor cell.

Explanation:

When one bacterium transfers its genetic material through direct contact to others. The bacterium transfers its genetic material called donor cell and one serves it called recipient cell.

There are mainly four steps in this process-

1. Connecting sex pilus to recipient cell by donor cell.

2. The Fusion of cell membranes and transfer of single strand of DNA to the recipient cell.

3. Each bacterium cell makes a complementary DNA strand.

4. Both bacterium cells separates.

B. After the pilas connection between the two bacteria, the cell wall is nicked, whereby the DNA of one cell is transferred to the other.

Activating the muscles involved in smiling may actually make us feel happier. this is an example of (the)

Answers

Activating the muscles involved in smiling may actually make us feel happier and this is an example of Facial feedback effect . The facial feedback effect states that skeletal muscle feedback from facial expressions can influence emotional experience. Facial movement plays a causal role in regulating emotional experience and behavior.

Final answer:

The idea that creating a physical smile can cause feelings of happiness is an example of the facial feedback hypothesis. This suggests that our facial expressions can impact our emotions, a concept backed by various studies. This is observed in universal expressions like laughter that signal joy or pleasure.

Explanation:

The statement that activating the muscles involved in smiling can make us feel happier is an example of the facial feedback hypothesis. This hypothesis suggests that facial expressions can influence our emotions. For example, physically forcing yourself to smile can potentially lead to a lighter mood. This concept has been examined in studies like the one by Soussignan in 2002, which found that a Duchenne smile, a genuine smile that involves the muscles around both the mouth and eyes, can trigger positive emotions and physiological responses. Similarly, laughter is a universal expression of joy or pleasure recognized across cultures. Strategies like these can be a part of successful happiness interventions, as seen in the study by Seligman et al., 2005 where participants recorded good things from their day and saw increases in happiness.
