Que sucedería con la especie humana si debido a una futura mutación genética sus células no pudieran realizar los procesos de mitosis y meiosis

Answers

Answer 1

Answer:

la vida no podría continuar sin los procesos de división celular  

Explanation:

La mitosis es el proceso de división celular mediante el cual se producen dos células idénticas a partir de una sola célula. Durante la mitosis la célula crece y duplica la cantidad de ADN, con lo cual exactamente el mismo contenido de información genética es trasmitido a las sucesivas células que el proceso de mitosis va a dar origen. Por otra parte, la meiosis es un proceso celular en el cual se producen dos divisiones nucleares y citoplasmáticas (meiosis I y meiosis II) las cuales son precedidas por una fase de replicación del ADN. En la especie humana, la mitosis da lugar a células diploides (2n) con dos set completos de cromosomas homólogos, mientras que la meiosis da lugar a cuatro células haploides (n) llamadas gametos (el gameto masculino es el espermatozoide y el gameto femenino es el óvulo) las cuales contienen la mitad del número cromosómico al de la célula de origen. En organismos eucariotas pluricelulares tales como la especie humana, la función de la mitosis es producir más células somáticas (soma: cuerpo) con idéntico material genético, mientras que la función de la meiosis es producir células aptas para el proceso de reproducción, es decir, células con la mitad del material genético que se fusionarán para generar una célula diploide o zigoto a partir del cual y mediante sucesivas mitosis se desarrollará un organismo adulto.

Discuss the benefits and drawbacks of
using solar energy and wind energy.

Answers

Answer:

hmm I'd say something like "Solar and Wind energy systems are renewable sources and ultimately are healthier for the planet, the drawback is that other resources (i.e oil and coal) tend to be cheaper"

Answer:

Solar Energy:-

Benefits-

Solar power is completely cleanIt produces no air pollution, no water pollution, no greenhouse gas effects and carbon - free alsoNo harmful emissions are released when electricity is being produced by solar panels.It also reduces the need for finite resources.

Drawbacks-

Solar Energy Storage Is ExpensiveUses a Lot of SpaceIts Weather-Dependent, slthough solar energy can still be collected during cloudy and rainy days, the efficiency of the solar system drops.Initial cost of purchasing a solar system is fairly high.

Wind Energy:-

Benefits-

Wind is a domestic source of energyIt's a clean fuel sourceIt's sustainable and causes no harmful emissions. Wind energy is a green energy source and does not cause pollution.

Drawbacks-

Wind turbines are prone to noise disturbances.The wind is inconsistentWind turbines involve high upfront capital investment.Installation can take up a significant portion of land.

Item 5 What is the role of a generator in producing electricity? The generator stores electrical energy for later use in homes and businesses. The generator spins the turbine to create mechanical energy. The generator transforms the mechanical energy of the turbine into electrical energy. The generator reverses the turbine to create electrical energy.

Answers

Answer:

The generator transforms the mechanical energy of the turbine into electrical energy

Explanation:

Electricity generator is a device that is used in generating power supply which can be used in industries, homes and for commercial and private purposes.

It operates by converting mechanical energy into electrical energy for the use in an external circuit. mechanical energy can be obtained from steam turbines, internal combusting energy, gas and water turbines and it can be obtained through the rotating shaft.

The capacity of each generator determines the amount of energy it can supply to a given place.

12. Flowers whose reproductive structures consist only
of stamens would be able to produce
A) fruits with seeds
B) fruits without seeds
C) pollen
D) ovules

Answers

Answer:

Pollen reproductive structures consist only

of stamens would be able to produce

Explanation:

No C is the answer

Reproductive structures are structures that make up the reproductive organs of a particular organism. These structures could include either female or the male reproductive organs.

Flowers with reproductive structures that comprise of only stamen would produce only pollen (option c).

Stamens are reproductive organs found in plants and they are male reproductive organs. For fruits with seeds to be formed the male and female reproductive organs must come together to produce a fruit.

Flowers with only the stamen will produce only pollen which is a male gamete that needs to be joined to the female gamete, ovary produced from the female reproductive structure (pistil) in a plant to produce a fruit.

Imagine carefully weighing a metal can, leaving it out in the rain for weeks and weeks until it was very rusted, and then carefully weighing it again. Would the can be heavier or lighter after it was rusted?

Answers

Answer:

The answer would be heavier, though it depends upon the type of metal. Rusting is essentially corrosion. Rust is often caused by a piece of metal getting soaked in water and then being exposed to oxygen. The rust will add more weight to the can so it becomes heavier.

Leaving out metal can in the rain for weeks and weeks until it was very rusted, and then if we carefully weighing it again it can be found that the can weighs more because the rust deposited on the metal can adds more weight.

What is rust?

Rust is referred to as an iron oxide, and a form of corrosion which is caused by a chemical reaction which affects masses of iron and steel.

Once formed, rust starts to eat away at the metal, forming a flaky, orange red coating which weakens the iron. It occurs when the metal reacts with oxygen and water.
