The correct answer is option C, that is, regulate water loss.  

Guard cells refer to the cells enclosing each stomata. They assist in monitoring the rate of transpiration by closing and opening the stomata. The guard cells possess the tendency to monitor the closing and opening of stomata by changing shape. The shape of the guard cells modifies on the basis of the concentration of potassium ions and water found in the cells themselves.  

The stomatal pores get closed when carbon dioxide is no longer needed for the process of photosynthesis. The guard cells swell when movement of water takes place inside these pores, and thus, the opening of stomatal pores occurs, and as water moves out, the guard cell closes. Thus, guard cells play an essential role in regulating water loss.

aleksandr82 [10.1K]

Answer:

Maintenance of postural equilibrium is an integrated process requiring optimal muscular balance, joint dynamics, and neuromuscular efficiency using visual, vestibular, and proprioceptive inputs.

Explanation:

Maintaining postural equilibrium involves multiple parts of the body, and can be divided in two levels of control: the first one being on the brainstem, the cerebellum and the spinal cord; and the second one including cortical areas that participate in multisensory integration and control as well as the basal ganglia located in the cerebrum.

5. a. What technology produced the results illustrated here, and what is this
notsponge [240]

The technology that was used to produce the results illustrated in the image is gel electrophoresis and it is used for separating deoxyribonucleic acid (DNA) fragments.

Gel electrophoresis can be defined as a technology that is used in the laboratory for the separation of mixtures of deoxyribonucleic acid (DNA), ribonucleic acid (RNA) or other macromolecules such as proteins based on molecular size and charge.

In gel electrophoresis, an electric current is applied to the deoxyribonucleic acid (DNA) samples so as to create fragments that can be used to compare the various samples of deoxyribonucleic acid (DNA).

The steps involved in gel electrophoresis include the following:

  • Extraction of deoxyribonucleic acid (DNA).
  • DNA isolation and amplification.
  • Addition of deoxyribonucleic acid (DNA) to the gel wells.
  • Application of an electric current to the gel.
  • The separation of DNA bands based on molecular size and charge.
  • Deoxyribonucleic acid (DNA) bands are stained.

Y_Kistochka [10]

Answer:

The citric acid cycle is fundamental to produce the energy needed for aerobic cell metabolism, thereby mutations in the enzymes involved in this metabolic pathway would be lethal to the individual

Explanation:

In aerobic organisms, the citric acid cycle (also known as the Krebs cycle), is a key metabolic pathway used to remove electrons and uses them in the electron transport chain in order to generate adenosine triphosphate (ATP), the energy currency of the cell. The citric acid cycle depends on eight enzymes that oxidize acetyl-CoA into two molecules each of carbon dioxide (CO2) and water (H2O). Thus, the citric acid cycle is a series of chemical reactions that are key to breakdown carbohydrates, fats and proteins into CO2 and H2O in order to produce energy (ATP).
