Difference between male and female gamete​

Physics
2 answers:
Inga [223]3 years ago
5 0

Answer:

The male gamete is smaller in comparison to that of the female gamete.

The male gamete is conical from the front while the female gamete is spherical.

The cytoplasm in the male gamete is less in comparison to that of the female gamete.

The male gamete can move with the help of the tail while the female gametes are immobile and do not have any tail or flagella present.

The number of mitochondria present in the sperm is less than the number of mitochondria present in the ovum.

The male gamete has acrosome present in the head region that contains enzymes for dissolving the membranes present around the ovum. The ovum does not contain such digestive enzymes.

Answer:

MALE GAMETES:

1)A male gamete is the male reproductive cell, which unites with the female gamete to produce the zygote.

2)Produced by spermatogenesis.

3)Produced in testes.

4)Smaller than female gametes.

5)Swims using tails.

6)Uses sugar in seminal fluid.

FEMALE GAMETES:

1)A female gamete is the female reproductive cell, which unites with male gamete to form the zygote.

2)Produced by oogenesis.

3)Produced in the ovaries.

4)Larger than male gametes.

5)Does not move by itself.

6)Uses protein and fat in the cytoplasm.

in short

Gametes are an organism's reproductive cells. They are also referred to as sex cells.

Female gametes are called ova or egg cells,  and male gametes are called sperm. In contrast, each egg cell, or ovum, is relatively large and non-motile.

A body is projected vertically upwards with a speed 100 m/s from the ground then distance it covers in its last second of its up
Valentin [98]

The distance travelled by the body on last second of its upwards journey is 4.935m

What is projectile motion?

A projectile is an object or particle that is launched toward the surface of the Earth and moves along a curved path only under the influence of gravity.

To solve this question, consider the horizontal distance to be H and

distance traveled by the body in the last second be d

H=U^{2} /2g

H=100^{2} /2*9.8

H=510.2m

Now time taken to reach a height of

510.2 m= \sqrt[n]{2H/g}

=10.2 seconds

Now,

s=ut+1/2gt^{2}

H-d= (100)(t-1)-1/2g(t-1)^{2}

510.2-d=100*9.2-1/2*9.8*9.2^{2}

d=4936m

So, the correct answer is '4.936m'.

A metallic conductor has a resistivity of 35 × 10 −6 Ω⋅m. What is the resistance of a piece that is 20 m long and has a uniform
Nitella [24]

Answer:

Therefore the resistance of the conductor is 175Ω

Explanation:

Resistance:

  • Resistance of a metallic conductor is directly proportional to its length(l).
  • Resistance of a metallic conductor is inversely proportional to its cross section area(A).

The notation sign of resistance is R.

The unit of resistance is ohm (Ω).

Therefore,

R \propto l

and

R \propto \frac{1}{A}

\therefore R\propto \frac{l}{A}

\Rightarrow R=\rho \frac{l}{A}

ρ is the proportional constant.

It is also known as resistivity of that metal.

Given ρ=35×10⁻⁶Ω-m

l= 20 m

A= 4.0×10⁻⁶m²

\therefore R=35\times 10^{-6}\times \frac{20}{4.0\times 10^{-6}}

       =175Ω

Therefore the resistance of the conductor is 175Ω

 explain why earths acceleration is usually very small compared to the acceleration of the object the earth interact with
Marianna [84]

Answer:

F-ma

Explanation:

If you are speaking of objects like satellites, etc. then their mass is much less than that of the Earth. A good approximation is Newton's first law of motion:

Force = Mass ×  Acceleration

often written:

F = m a

The gravitational force is the same between the Earth and the object - only the mass differs. So the acceleration is inversely proportional to the mass.
