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).

</span><span>Macrocytic anemia is lack of red blood cells that caused by B12 deficiency. Vitamin B12 is mostly found in animal products (eggs, dairy product or honey) so vegan will have increased risk of deficiency. Vegetarian that doesn't eat meat also at risk of iron deficiency that will cause microcytic anemia.</span>

TRUE OR FALSE<br><br> Both animal and plant cells use cellular respiration to make energy.

Radda [10]

Answer:

It's responsible for cellular respiration in both plants and animal cells. The difference is that plants also have chloroplasts that perform photosynthesis. Animals get their energy by eating food, digesting it, and turning it into the base sugars, proteins, and lipids that the cells can burn to perform cellular respiration (which makes ATP).

Identify the MOST specific taxonomic level.

UNO [17]

Answer:

Species

Explanation:

Species is the most specific and basic taxonomic level of classification and also the basic unit of biodiversity. Species is defined as group of highly closely related organisms that mate or breed to produce fertile offspring. After species genus is specific, and mostly organisms names are identified by species names and genus names as in binomial nomenclature, all scientific names are derived from genus and species e.g. the scientific name of frog is <em>Rana tigrina, </em>here '<em>Rana</em>' is genus name that is always capitalized and '<em>tigrena</em>' is species name that starts with small letter but both are always written in italics or underlined.

A molecule that has regions of partial positive and partial negative charge

nasty-shy [4]

Answer:

A) polar

Explanation:

Polar molecules contains partial positive and partial negative charge as in all polar molecules two atoms have unequal sharing electron. Due to unequal sharing of electrons, one atom that attracts valence electrons strongly gains positive charge and other gain negative charge.

For example water, water is a polar molecule having partial negative and partial positive charge because the oxygen atom in water attracts electrons more strongly than the hydrogen atoms.

Hence, the correct answer is "A) polar".
