Answer:

Category D

Explanation:

In the USA, the Federal Animal Welfare Regulations require that research laboratories report animal use according to the species as well as the number of individuals subject to experimentation procedures. Moreover, animal use for research/teaching purposes is also reported according to the classification by pain and distress categories. Basically, this classification has four categories (B,C, D and E) in increasing order according to the pain level suffered by research animals. Animals within Category D include those subjected to potentially painful or stressful procedures. In consequence, in this category, it is imperative the utilization of proper anesthetics and/or analgesics in order to diminish the pain and suffering of these animals at the lower level possible.

While listening to sad rather than happy music, people are more likely to perceive a spoken work as mourning rather than morning
Shtirlitz [24]

Answer:

top-down processing

Explanation:

  • When the perception is formed starting from a larger concept or object and then it is focused on to more detailed information, then such a method of forming perception is termed as top down processing.
  • This processing takes into consideration the general impressions and then focusing on the finer details to make a final perception.
  • Due to the top down processing the circumstances under which a particular emotion or object is perceived influences our expectations in that particular situation.
  • Therefore, when we listen to sad music our brain already perceives that the word spoken would be in context to the current situation and hence, the word gets perceived as mourning rather than morning and this is an example of top down processing.

earnstyle [38]

The options are incomplete and have been listed incorrectly. Complete question has been attached.

Answer:

C) Dd and Dd

What is the purpose of redox reactions in the cell?
Phoenix [80]

Answer:

To discharge energy gradually in a step-by-step process.  

Explanation:

The process of cellular respiration comprises various reactions in which electrons are transferred or mediated from one molecule to another. The reactions taking part in electron transfers are called redox reactions or oxidation-reduction reactions.  

With the movement of electrons the energy is released that can be captivated and is used to do work. In cellular respiration, the electrons from glucose move slowly via the electron transport chain ultimately towards oxygen that is, transferring towards lower and lower energy states and discharging energy at each stage.
