You remove pus from a wound and try to identify the pathogen multiple ways. The multi-locus gene tree showed your organism was most closely related to Streptococcus pyogenes but the 16S tree said it was most closely related to Streptococcus pneumoniae. Describe why this might be the case and other ways you should try to identify this organism.

Answers

Answer:

It occurs because phylogenetic analyses based on the 16S rRNA gene sequences may have insufficient resolution for distinguishing between closely related species

Another genomic method for streptococcal identification is whole-genome analysis (WGS)

Explanation:

The phylogenetic analysis of the highly conserved 16S rRNA gene sequences has recently been used to distinguish between prokaryotic species. However, this gene sometimes may show low resolution to distinguish between closely related species, and it has been suggested potential horizontal transference of rRNA genes. Moreover, multi-locus sequence analysis (MLSA) has also been used to identify species. MLSA analysis consists of analyzing simultaneously different genes and this technique has shown to have a high capacity for establishing relationships between species within a genus or genera within a family. Finally, whole-genome analysis (WGS) is the most powerful tool for distinguishing between closely species. WGS is a technique that provides a very high resolution which is based on the analysis of large-scale genome sequencing data generated by next sequencing generation (NGS) technologies.

45 / 10000 Word Limit Question 2 (b) The membranes of both B cells and the cancer cells are largely composed of phospholipids. Explain how, when the membranes are fused, the polar parts of the phospholipids from one cell will interact with the phospholipids from the other cell and how the nonpolar parts of the phospholipids from one cell will interact with the phospholipids from the other cell.

Answers

Answer:

Hydrophobic tails interact among themselves, while polar (hydrophilic) heads interact with water

Explanation:

In the first place, the polar heads of the phospholipids localized on the membrane surface interact with surrounding water molecules that also surround other cell phospholipids. Second, the non-polar tails of the phospholipids from one cell interact with molecules that repel water in the other cell phospholipid. Consequently, it forms a bilayer structure composed of two sheets of phospholipids where hydrophobic tails are arranged on the inside of the membrane, thereby allowing the interaction tail-to-tail among different cell membranes, while the polar heads of the disrupted phospholipid membranes interact together with the surrounding water.

The covalent bonds between the oxygen and the hydrogen atoms result from a sharing of the electrons. This is what holds the water molecules themselves together. The hydrogen bond is the chemical bond between the water molecules that holds the mass of molecules together.hope the answer was helpful, mention me as brainliest.
I think the molecules are polar, with each partial positive end (Hydrogen) of one molecule attracted to the partial negative end (Oxygen) of another molecule. The cohesion of water molecules and its high surface tension hold water in droplets.

There are many reasons why all humans do not perceive sounds similarly in our environment, including adaptation, hearing loss and/or deafness.
For 2A-2D, first determine whether the scenario is an example of sensory adaptation, conduction deafness, sensorineural deafness, and/or central deafness.
Second, for the scenarios that are examples of deafness, explain briefly how the scenario leads to deafness (i.e., how does the scenario alter normal auditory processing). If you have selected sensory adaptation as an answer, explain briefly why the scenario does not fall under the categorization of deafness. Use your own words to briefly explain - simply listing definitions is not sufficient. (2.5 points each for matching, 5 points each for correct justification)
2A. Listening to excessive loud noises everyday over years that causes loss of stereocilia
2B. Hearing construction outside when it first begins, but no longer noticing the sound minutes later
2C. Difficulty understanding speech, but no damage to ears or ability to understand nonverbal sounds
2D. A hole in the tympanic membrane caused by an ear infection

Answers

Answer: 2A Sensorineural deafness

              2B Sensory adaptation

              2C Central deafness

              2D Conductive deafness

Explanation: The human ear is divided into 3 parts:

Outer Ear: auricle, ear canal and tympanic membrane;Middle Ear: eardrum, tympanic cavity and ossicles (malleus, incus and stapes);Inner Ear: oval window, semicircular ducts (attached to cochlea and nerves), cochlea and auditory tube;

The Sensorineural deafness is a type of deafness caused by a damage in the inner ear, either the cochlea or the auditory nerve. It can happen because of medicine toxicity, exposure to noise along the years etc.

So, from the scenarios above, 2A is consistent with sensorineural deafness  since stereocilia are hair cells of inner ear.

Sensory adaptation is a phenomenom that happens when an individual's sensory receptors is exposed to a stimuli for a prolonged period of time. For example, the situation described in 2B. It is not considered deafness because it is not caused by a damage in any part of the ear.

Central deafness is a very rare case of deafness. The damage in this type of deafness is in the brain and not in any of the 3 parts of the ear. That's why the scenario in 2C is the example of this.

Conductive deafness is the second most common type of ear problem and it occurs in the outer ear. One of the causes is blockage in the ear canal by the ear wax, external bodies, osteomas (bone growth) or otitis (oute ear infection). An example of this type of deafness is scenario 2D.

LIPIDS are one of the four major biomolecules in living systems. A form of lipids are fats which constitute most lipids i.e. predominant. Lipids also includes fatty acids, steroids and other molecules.

Lipid biomolecules readily dissolve in POLAR solvents such as hexane and chloroform. Because of their insolubility in water (polar solvent), fats and other biomolecules in this class are said to be NON-POLAR.

Triacylglycerols, also known as triglycerides, are forms of fat that is composed of a glycerol molecule bound to three molecules of FATTY ACIDS.

Based on the bonding of the carbon atoms in the chain, fats that contain chains with no double bonds are classified SATURATED FATS, while those that contain double bonds in the carbon chain are UNSATURATED FATS.

The correct answer is C. Wetland.

Explanation:

A wetland is a generic name for habitats located between hard ground and open water. Wetlands include, for example, wet and waterlogged shallow land, shallow lakes and seas, marshes, floodplain forests, and flowing waters.

Wetlands provide a breeding ground for many animal and plant species and can act as a buffer in flood areas and prevent severe and sudden floods. Rainfall, waters entering the catchment area, soil and ground elevation differences in the area, and water evaporation form the hydrological conditions of the wetlands. Wetlands are one of the most valuable and endangered habitats on Earth. Swamps, overgrown lakes, flood-prone areas, shallow bays, water-covered beach areas and mangrove beaches are all endangered habitats.
