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.
Thus, the correct answer is : state - dependent memory.

Answer:</h2>
<u>Blood clotting</u> is a positive feedback.
<h2>
Explanation:</h2>
All the physiological process occurring in the body are monitored by two types of mechanism called negative feedback and positive feedback.
Positive feedback is the reaction which occurs with the feedback from the actions the system has performed. The blood clot occurs with palette formation which is regulated with the blood lose (continuous feedback).
Negative feedback is a reaction that is the invert of the change distinguished, meaning it capacities to decrease the change. A change is recognized by a receptor and an effector is made to incite a contrary impact which facilitates further reaction.
The physiological process such as shivering, sweating and digestion are examples of negative feedback.
In prokaryotes, new mutations accumulate quickly in populations, while in eukaryotes, new mutations accumulate much more slowly. The primary reasons for this are prokaryotes reproduce quickly and have vast populations.
<h2> Prokaryotes V/S Eukaryotes</h2><h3>Prokaryotes</h3>
Prokaryotes are organisms consisting of cells that don't have cell nuclei or any organelles that are enclosed in membranes. It follows that prokaryote's DNA is not contained within a nucleus.
The following components could be found in a normal prokaryotic cell:
- The membrane enclosing and guarding the cell is known as the cell wall.
- All of the cell's internal components, excluding the nucleus, are called cytoplasm.
- Some prokaryotic cells have filaments made of proteins called flagella and pili.
- A nucleoid is a cell structure that resembles a nucleus and contains genetic material.
- A plasmid is a little DNA molecule with independent reproduction.
<h3>Eukaryotes</h3>
Eukaryotes are organisms made up of cells with membrane-bound organelles and a nucleus that contains DNA in the form of chromosomes. Eukaryotic organisms can have several cells or just one cell. Eukaryotes make up all animal life. Protists, fungi, and plants are examples of additional eukaryotes.

Answer:
The correct answer would be a lipid-soluble signal.
Signal transduction refers to the set or cascade of bio-chemical reactions take place in a cell in order to transmit the chemical or physical signal from outside the cell to inside target molecule.
It is usually initiated by receptors present on the membrane of the cell which sense the extracellular stimulus (such as ligand, hormone, pressure, temperature, pressure etc). Once activated, these receptors activate the cascade of reaction which ultimately reaches the target molecule and produces a cell's response.
In contrast, the lipid-soluble signals (such as steroidal hormones, thyroid hormone etc) enter the cell membrane without any hindrance. They directly bind to intra-cellular receptor present in the cytoplasm or on the nuclear membrane.
The hormone-receptor complex then enters the nucleus and act as transcription factor and produces the response in the form of transcription.
Answer:
Energetic coupling of chemical processes in metabolic pathways Biochemical systems couple energetically unfavorable reactions with energetically favorable reactions. These reactions can be part of catabolic pathways where complex substances are broken into simpler ones with the release of energy or anabolic pathways where complex molecules are synthesized with an input of energy.
