what is the main difference between sexual and asexual reproduction

Answers

Answer 1

Answer:

Asexual reproduction does not involve sex cells or fertilisation . Only one parent is required, unlike sexual reproduction which needs two parents. Since there is only one parent, there is no fusion of gametes and no mixing of genetic information.

Answer 2

The main difference between sexual and asexual reproduction is that sexual reproduction involves the fusion of gametes, while asexual reproduction does not.

In sexual reproduction, offspring are produced through the fusion of gametes (reproductive cells) from two parent organisms. This fusion, known as fertilization, results in offspring that inherit genetic material from both parents. This genetic recombination introduces variation in the offspring, promoting genetic diversity within a population.

In contrast, asexual reproduction involves the production of offspring without the involvement of gametes or the fusion of genetic material from two parents. A single parent organism reproduces by generating genetically identical or near-identical offspring through various methods such as budding, fragmentation, or binary fission. Asexual reproduction typically leads to offspring that are genetically identical to the parent, lacking the genetic diversity observed in sexual reproduction.

What is responsible for the unusual chemical properties of water?

Answers

Answer:

hydrogen bonds

Explanation:

pls choose it as brianliest

The unusual chemical properties of water is due to its polar covalent bond.

What is polar covalent bond ?

When atoms with differing electronegativities are shared between two atoms in such a covalent link, the result would be a polar covalent bond.

What is water ?

Water is a kind of mixture of hydrogen and oxygen . Its chemical formula will be [tex]H_{2}O[/tex].

Along with its polar covalent connections, water displays a variety of interesting features. Because oxygen has a higher electronegativity than hydrogen, electron pairs were drawn closer to the oxygen atom, causing it to be partially negatively charged. As a result, both hydrogen atoms acquire a slightly positive charge.

Therefore, polar covalent bond will be responsible for unusual chemical properties of water.

Question:-

If a solid object is taken from Earth far into space, which of the following measurements of the object will change the most?

A. density

B. mass

C. volume

D. weight

Answer:-

option D. weight

in a battery that uses a licoo2 cathode approximately 50% of the lithium migrates from the cathode to the anode on charging. in a battery that uses a limn2o4 cathode what fraction of the lithium in limn2o4 would need to migrate out of the cathode to deliver the same amount of lithium to the graphite anode?

Answers

Answer:

92.4%

Explanation:

Assume 100g of the cathode material. The LiCoO2 cathode has 7.09 g of Li.  If half of Li migrates during charging, 3.55g Li migrates. 100g of the LiMn2O4 cathode contain 3.84g of Li. The fraction of lithium in LiMn2O4 that would need to migrate out of the cathode to deliver the same amount of lithium to the graphite anode:

(3.55g/ 3.84g ) * 100% = 92.4%

From electrolysis, 92.4% would need to migrate out of the cathode to deliver the same amount of lithium to the graphite anode.

What is electrolysis?

Electrolysis is a technique that uses direct electric current (DC) to drive an otherwise non-spontaneous chemical reaction. Electrolysis is commercially important as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell. The voltage that is needed for electrolysis to occur is called the decomposition potential.

The fraction of lithium in LiMn₂O₄ that would need to migrate out of the cathode to deliver the same amount of lithium to the graphite anode:(3.55 g/ 3.84 g ) × 100% = 92.4%

Excited hydrogen atoms emit light in the ultraviolet at 2.47x1015Hz. What is the
energy of a single photon with this frequency?

Answers

The energy of a single photon of this frequency is 1.638 × 10⁻¹⁸ J

Using Planck's equation, the energy of the photon E = hf where h = Planck's constant = 6.63 × 10⁻³⁴ Js and f = frequency of ultraviolet light = 2.47 × 10⁻¹⁵ Hz.

Substituting the values of the variables into the equation, we have

E = hf

E = 6.63 × 10⁻³⁴ Js × 2.47 × 10¹⁵ Hz.

E = 16.3761 × 10⁻¹⁹ J

E = 1.63761 × 10⁻¹⁸ J

E ≅ 1.638 × 10⁻¹⁸ J

So, the energy of a single photon of this frequency is 1.638 × 10⁻¹⁸ J

If you begin with a saturated solution of sugar dissolved in water, and then you heat the solution, what type of solution will result

Answers

After beginning the experiment with a saturated solution, then increasing the heat, we will be left with an unsaturated solution.

To obtain the saturated solution, we must dissolve sugar in the water. We can say that the solution has become saturated when the solution is no longer able to dissolve more sugar. It has reached its capacity for the solute that it can dissolve in these conditions.

However, the temperature of a solution has an effect on the dissolving limit of the solution. That is, when a solution is heated it becomes able to dissolve more solute. Therefore, if we were to heat a saturated solution, it will be able to dissolve more solute and therefore will no longer be at its limit, meaning it is no longer a saturated solution. It has become unsaturated.

What mass of hydrogen is needed to react with 32 g of copper oxide?
CuO + H2 → Cu + H2O

Answers

Answer:

1.22gram of hydrogen is needed to react

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore,  0.40 g mass of hydrogen is needed to react with 32 g of copper oxide.

What is mole?

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.

Mathematically,

CuO + H[tex]_2[/tex]→ Cu + H[tex]_2[/tex]O

mole of copper oxide=  32 /79.54

                                    =0.40 mole

The mole ratio between copper oxide and hydrogen is 1:1

mole of hydrogen= 0.40 mole

mass of hydrogen = 0.40 mole×1g/mol

                              = 0.40 g

Therefore, 0.40 g mass of hydrogen is needed to react with 32 g of copper oxide.

Answer:humans have put ridiculous amounts of carbon dioxide into the atmosphereThese events are linked to the mass burning of fossil fuels to meet an increase in human demand

So the answer is True

Explanation:

Burning fossil fuels, such as coal and oil, has increased the quantity of greenhouse gases in our atmosphere since the Industrial Revolution began around 1750.

What is atmosphere?

Atmosphere is defined as a layer of gas that surrounds a planet and is kept there by the gravitational pull of the planetary body. The atmosphere of Earth includes five primary layers and a number of minor ones.

Industrial revolution is defined as the transition of an economy based on agriculture and handicrafts to one driven by industry and machine production. The causes of industrial revolution are the advent of capitalism, European imperialism, efforts to mine coal, and the effects of the Agricultural Revolution are some of the factors that historians have recognized as contributing to the Industrial Revolution.
