When a protein denatures, which type of bonding is effected?
GenaCL600 [577]

Answer:

When a protein is denatured, secondary and tertiary structures are altered but the peptide bonds of the primary structure between the amino acids are left intact. Since all structural levels of the protein determine its function, the protein can no longer perform its function once it has been denatured.A protein becomes denatured when its normal shape gets deformed because some of the hydrogen bonds are broken. Weak hydrogen bonds break when too much heat is applied or when they are exposed to an acid (like citric acid from lemon juice).

Does peterson's solution to the mutual-exclusion problem shown in fig. 2-24 work when process scheduling is preemptive
Sloan [31]
<span>Yes. Not only does Peterson's Solution work with preemptive scheduling, but it was designed for that very case. In fact, when scheduling is non-preemptive, there is a possibility it might fail. For example, in a case where 'turn' is initially 0, but process 1 runs first, it will loop perpetually, and never release the CPU.</span>

The plant kingdom is divided into 2 groups vascular and nonvascular. describe each subclass. include key words such as vascular
BaLLatris [955]
<h2>Vascular and Nonvascular Plants </h2>

Explanation:

Kingdom Plantae on the basis of vasculature is divided into two groups-vascular and non-vascular plants .

  • <u>Vascular plants </u>or tracheophytes have a proper tissue-level organization and true shoot and root structures like leaves, stem, flowers, root etc
  • The tissue system or vasculature of vascular plants compromises of vascular tissues like tubular vessels – xylem and phloem
  1. The xylem transports nutrients to various parts of the body from the leaves.
  2. Phloem conducts water and other nutrients from the roots to various parts of the plant .
  • These are flowering plants that include the phanerogams – angiosperms and gymnosperms and bears flowers and fruits like the cedars, pine, clubmosses, lilies, sunflower etc.
  • Dicots are with tubular vasculature.  
  • Non-vascular plants or bryophytes with an absence of proper tissue-level organization and true shoot or root systems
  • <u>Nonvascular plants</u> are small. Their transport mechanism is poor due to lack of vascular tissues
  • These plants are lack proper shoot or root system.
  • It includes mosses, hornworts etc.
  • Monocots are plants with scattered tube-like vessels .
