Why is it not surprising that staphylococci are the leading cause of wound infections?

1 answer:

7 0

This genus is promptly present as a piece of the ordinary microbiota on the vast majority's skin, so it could without much of a stretch enter wounds. Staphylococci are Gram-positive cocci around 0.5 – 1.0 μm in width. They develop in groups, sets and sporadically in short chains. The bunches emerge in light of the fact that staphylococci partition into two planes. The arrangement of the cocci recognizes micrococci and staphylococci from streptococci, which more often than not develop in chains.

Which is a result of a seasonal change (meaning a change that happens over

weqwewe [10]

Answer:

A. Chipmunks sleeping underground through the winter

Explanation:

A seasonal change in the behavior of a living organism is a change that occurs every year at a particular time. The reasons for the occurrence of such changes are so that the organism has advantage in survival in the environment. In this case we have the chipmunk that sleeps underground through the winter. We have an animal which exhibit a seasonal change every year, during the winter period. The reason for this is that the chipmunks have very quick metabolism, so if they are active during the winter they will starve because of lack of food. Instead, the chipmunks have evolved to hibernate during the winter, thus slowing down the work of their hurt during the winter and sleep, until the spring comes.

Which statement is true about extracted lipid?

SSSSS [86.1K]

Answer:

The right answer is (B) the extracted lipids cover twice the surface area of the intact red blood cells.

Explanation:

To explain this statement is necessary to take into consideration the structure of a lipid. On the first place lipids that form membranes are called phospholipids, this means they have one 'head' that is hydrophilic and a tail composed by the lipidic chain that is hydrophobic.

In a biologic context, the phospholipids form the cellular membrane. They do so by a bi-layer disposition, meaning that one the external side of the cell there is a layer of phospholipids with the hydrophilic head and in the internal side, there is a second layer of phospholipids with the hydrophilic head. The hydrophobic 'tails' are in the middle. This disposition is due to the fact that both the external and the internal environments are water based.

Therefore, since each cell has a bilayer membrane of phospholipids, when the cells are dissolved and all the lipids that used to form the membrane are put together, they will occupy twice the surface of the red blood cells.

HELP!!!! FAST!!!! 20 POINTS!!!! You are a traffic accident investigator. You have arrived at the scene of an accident. Two truck

Minchanka [31]

Answer:

1) Kinetic energy of the truck 1 is 600,000 joules.

Kinetic energy of the truck 2 is 1,837,500 joules.

2 a)Potential energy of truck 1 is 646,800 Joules.

b) Energy lose by the truck 1 just got converted into heat and sound energy during the collision.

Step-by-step explanation:

Mass of the truck 1 and truck 2,m = 3000 kg

Velocity of the truck 1, = = 20 m./s

Velocity of the truck 2, = 35 m./s

1. Kinetic energy of the truck 1:

Kinetic energy of the truck 2:

2.a) Energy loose by the truck 1:

Initial height of the truck on the hill = 22 m

At that height potential energy will be maximum:

Potential energy of truck 1 at that height =

b) Energy lost by the truck 1 just got converted into heat and sound energy during the collision.
