Sedimentary rocks<span> can be categorized into three groups based on sediment type. Most sedimentary rocks are formed by the </span>lithification<span> of </span>weathered<span> rock debris that has been physically transported and deposited. During the transport process, the particles that make up these rocks often become rounded due to abrasion or can become highly sorted. Examples of this type of sedimentary rock include </span>conglomerate<span> and </span>sandstone<span>. Scientists sometimes call this general group of sedimentary rocks </span>clastic<span>. The remaining types of sedimentary rocks are created either from chemical precipitation and crystallization, or by the lithification of once living </span>organic matter<span>. We identify these sedimentary rocks as being </span><span>non-clastic
So the Answer Would Be C</span>
There are three main factors that affect the mutation rates in an organism. The three are:
1. <span>Frequency of Primary Changes in DNA
2. </span><span>Probability of Repair
3. </span><span>Probability of Recognition</span>
Thick or dense smears less likely to provide a good smear preparation for microscopic because it will diminish the amount of light that can pass through making it difficult to visualize the morphology of single cells under the microscope. Some times the stain can't penetrate all of the bacteria.
<h3 /><h3>What is a microscopic smear?</h3>
- A smear is a microscopic specimen.
- A swab or loop, or the edge of another slide, is used to spread the sample to be examined, such as blood or microbial culture, thinly and unevenly across the slide.
- Smear preparation involves spreading a small amount of sample on a slide and air drying the film before staining and microscopy.
- The conventional method, blood film method, drop and rest method, and water-wash method are the four types of smearing methods.
- Smear microscopy entails collecting a biological sample (typically sputum or other clinical material), fixing it thinly on a glass slide, and staining it with a dye that binds specifically to mycobacteria (making them easier to identify under a microscope).

Animal behavior researchers often refer to an activity associated with punishment or reward as an operant. The basis for training animals is the operant conditioning. It is a learning process where the animal would learn base from its behavior as it responds to its environment. In this type of learning, the behavior is either increased or decreased by the results that follows the action. It uses rewards and punishments in order to associate with the behavior. For instance, you are trying to teach your dog to fetch an object, if he succeeds in fetching the object, then you give your dog a treat. The dog would think that what it is doing is good and that it would get a reward from it so it would start learning the behavior.
