Acid-fast and Gram is used to visualize the structures in a membrane.

It is a differential staining procedure which is used to identify, <em>mycobacterium tuberculosis and M. leprae.</em>

Acid-fast bacteria are considered to be gram-positive in terms of their structure as, they contains peptidoglycan in its cell wall.

They stain poorly with Gram stain procedure, and appears as weak Gram-positive.

Membranes are consisted of lipid bilayer, which is doubled layer of phospholipid, glycolipid and cholesterol molecules, which contains the chains of fatty acids, and

<em>determines weather a membrane is formed into long flat sheets or round vesicles.</em>

To examine the membrane protein structure, Electron microscopy technology is used and it enables the visualization of single protein at nanometers resolution.

Which of the following serves as an advantage to using numerical taxonomy?

spayn [35]

Visual traits, like cell shape and size, are the most important criteria for determining similarity between species. thus option C is correct.

<h3>What is the significance of numerical taxonomy?</h3>

In biological systematics, numerical taxonomy is a categorization scheme that deals with the numerical grouping of taxonomic units according to their character states. Instead of employing a subjective assessment of their qualities, it seeks to construct a taxonomy using numerical procedures like cluster analysis.

The data produced can effectively be used in the design of better keys and classification systems because numerical methods are more sensitive in delimiting taxa. Numerous biological ideas that have long been accepted have been reexamined in the context of numerical taxonomy.

➷ Deforestation can contribute to global warming. Trees take in the carbon dioxide in the atmosphere, therefore, removing these would mean there is more carbon dioxide in the atmosphere. Also, growing certain things can release more greenhouse gases into the atmosphere. For example, rice cultivation releases methane into the atmosphere. Furthermore, growing livestock would increase methane emissions. This would mean the global temperature would increase due to global warming.

b) Permacultures may be used. These mimic natural processes and create sustainable and self - sufficient ecosystems. Another method would be stacking. This is where more things are grown in a given space. The plants would absorb more carbon dioxide from the atmosphere.

➶ Good Luck (:

How has fish adapted to its environment to minimized water resistance?

Debora [2.8K]

Fish breathe by drawing water in their mouths and forcing it out of the body via a number of gill slits. The gill slits are rich in blood vessels, enabling the direct absorption of oxygen. While all fish have gills, some fish are also able to extract oxygen from the air via gulping.

Most fish have swim bladders that are permanently sealed, but other fish have swim bladders that can hold varying amounts of air. Salmon have open swim bladders, and they must gulp air at the surface to keep them full. Some fish, such as sharks, lack swim bladders entirely. This causes them to sink if they do not maintain forward motion.

Fish have fins that are adapted to their lifestyle. Some have evolved into long, barbed structures, suitable for defense. Other fish have fins suited for achieving great speed or for walking along the bottom of the ocean.

Could Elodea from a freshwater lake be expected to survive if transplanted into the ocean?

Alina [70]

No. Because ocean is hypertonic and will result in wilting due outward movement of water.
