Which part of the cell cycle is disrupted when you get a sunburn?

Biology
1 answer:
sergey [27]3 years ago
7 0

Answer:

UV radiation basically damages skin by transferring energy to molecules in your skin, such as DNA, fat, proteins, etc. These molecules, which are already in their proper arrangement, absorb this energy. If the molecules absorb enough energy, the bonds holding them together can break, forming a new shape completely. For a cell that already has been chugging along smoothly thanks to specific molecules with specific shapes doing specific jobs, this is a big deal and causes serious problems.

Explanation:

UV radiation damage to DNA is a particular problem. DNA is a huge molecule and actually quite fragile. When a molecule of DNA is present in a cell, it resembles a zipper: it has two strands, with each strand tightly bound to corresponding molecules on the opposite side, called bases.

Which factor will not affect the strength of a solenoid
antoniya [11.8K]

Answer:  A solenoid is a long coil of wire wrapped in many turns. When a current passes through it, it creates a nearly uniform magnetic field inside.

 * Solenoids can convert electric current to mechanical action, and so are very commonly used as switches.

 *  The magnetic field within a solenoid depends upon the current and density of turns.

 * In order to estimate roughly the force with which a solenoid pulls on ferromagnetic rods placed near it, one can use the change in magnetic field energy as the rod is inserted into the solenoid. The force is roughly

                

                                                  change in magnetic field energy

                force on rod      =   ---------------------------------------------------

                                                  distance rod moves into solenoid

 * The energy density of the magnetic field depends on the strength of the field, squared, and also upon the magnetic permeability of the material it fills. Iron has a much, much larger permeability than a vacuum.

 * Even small solenoids can exert forces of a few newtons.

=> AFFECTS OF STRENGTH OF SOLENOID:

There are many factors and I cannot go fully into them here.

* Materials, size and duty of the solenoid all affect the operation. A solenoid, as you know, is a coil with an element which moves as a result of power being applied and removed. A simple switch.

* Clearly the more windings you have for set conditions of voltage will generate a greater field strength. The windings excite a core and the material of that core has a significant effect.

* The moving element can easily be made to suit power transfer requirement.

* So you need to understand application and work backwards. There may even be a solid state solenoid which can do the same thing.

You are assisting in a delivery of a​ 41-week, 3-day gestation infant being born to a mother with gestational diabetes. The head
Ahat [919]

Answer:

Shoulder dystocia

Explanation:

  • If during the vaginal cephalic delivery, there is a requirement of additional obstetric maneuvers after the head of the fetus has been delivered however the gentle traction is failed then this condition is known as shoulder dystocia.
  • Shoulder dystocia occurs when the shoulder of the baby gets stuck in the pubic bone of the mother after the head has been delivered due to which the baby retracts his head back into the birth canal.
  • Gestational diabetes is one of the conditions that impose a risk on the baby to have shoulder dystocia during the delivery.
  • Since in the given question it is mentioned that the mother has gestational diabetes and the head has been delivered but seems to retract back, this points out that the condition suspected is shoulder dystocia.

Describe the main difference between primary and secondary succession.
frosja888 [35]

Answer:

Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lack soil.

Secondary succession is one of the two types of ecological succession of a plant's life. It is the process started by an event (e.g. forest fire, harvesting, hurricane, etc.) that reduces an already established ecosystem (e.g. a forest or a wheat field) to a smaller population of species, and as such secondary succession occurs on preexisting soil whereas primary succession usually occurs in a place lacking soil.

Explanation:

Primary succession takes time for completion around 1000 years, whereas secondary succession area takes 200 years for completion. In primary succession, there is a lack of soil and humus for the sustaining of life whereas, in secondary succession, soil and humus are present with some organisms.

A Secondary succession can take a few hundred years.
