analogous structures

The right answer is analogous structures.

It is nevertheless interesting to note that several years before, a competition took place rather quickly between two types of mammals: the placentals and the marsupials, the Evolution having given in each of these two groups also armed individuals as we will see it next (We speak then of parallel evolution, that is the acquisition of similar characteristics in two species occupying the same space, not to be confused with a convergent evolution which gives identical attributes to two populations existing at times or in different ecosystems).

Prokaryotic bacteria are surrounded by a ____________ that contains the ____________ to regulate the entry and exit of materials
lukranit [14]

Prokaryotic bacteria are surrounded by a cell membrane that contains the transport proteins to regulate the entry and exit of materials through the cell, the cell wall to help maintain cell shape and structure, and the capsule, which aids against drying out and protects bacteria from a host's immune system.

<h3><u>Explanation:</u></h3>

Bacteria are the prokaryotic organisms that are found in every part of Earth. These organisms do have an interesting ultrastructure. The coverings of the bacteria are three in layer. They are

A. The outer capsule.

B. The middle cell wall.

C. The inner cell membrane.

The capsule is the outermost covering of bacteria that is formed of different slimy materials. These materials contains hygroscopic substances which can absorb water from the surroundings even when the water concentration in outside is very very low. This layer of protection outside bacteria help them to protect themselves against drying out at dry conditions.

The middle cell wall is formed of polymers of N acetyl glucosamine and N acetyl muramic acid. This layer is chitin in nature and is strong enough to maintain the shape and size of bacteria irrespective of outer conditions.

The innermost layer of bacteria is cell membrane which is formed of proteins and lipids bilayer and this cell membrane contains different transport for proteins which help in transport of different substances like water and nutrients inside the cell by means of active transport or passive diffusion.

Assuming the Chart Tracking software will not be intelligent enough to locate information that was not documented in the correct
pantera1 [17]

The usage of EHR can enable the training to adjust all the more effectively to the new framework, which will provide profit for patients, doctors and staff.

Explanation:

In the initiation process EHR includes a multidisciplinary way to deal with set up the new framework, guarantee protection and security consistence, plan rehearse work process and also they deal with appropriation procedure.

There are nine steps for successful implementation of EHR they are Create an implementation team, Configure the software, Transfer  data, Providing the physician liaison ROI, Driving referrals through physician preference.

The skills are needed in health information technology with the expanding usage of electronic well being records and the utilization of illness .

In the event the training is recorded as paper based and the longitudinal record is an essential idea for the training member.

The advantages and disadvantages of using this software analyzing chart is the utilization of subjective information examination programming incorporate being liberated from manual and administrative errands, sparing time and having the capacity to manage a lot of subjective information.

Thus the analysts have methodological ways to deal with utilizing subjective information investigation programming as they could fit between research strategies and structure.

Which type of cell adhesion is useful for anchoring cells together and defending against shear forces on tissues
Angelina_Jolie [31]

Answer:

Desmosomes

Explanation:

Desmosomes are cellular structures that adhere to neighboring cells. Its function is to hold the epithelial cells together, associating the intermediate filament cytoskeletons of neighboring cells, thus forming a transcellular network with high resistance to mechanical traction. It thus allows the cells to maintain their shape and the epithelial sheet to exist in a stable form. Inside cells act as anchoring sites for intermediate rope-shaped filaments, which form a structural network in the cytoplasm providing a certain rigidity. Through these junctions the intermediate filaments of the adjacent cells are indirectly connected forming a continuous network that extends throughout the tissue.
