Asexual reproduction involves the production of offspring without the need for a secondary partner to contribute genetic information.

Pollination and mating are two forms of sexual reproduction, so B, C, and D are incorrect. A, because the new potato grows directly from the old without the contribution of new genetic material, asexually reproduces.

Answer:

(A) a new potato plant grows from a potato

Explanation:

Asexual reproduction is the kind of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only; it does not involve the fusion of gametes, and almost never changes the number of chromosomes.

In the case of a potato plant growing from the main potato, the singled parent potato is responsible for the development of the new offspring and  determines the genetic make up of the new plant and subsequent potatoes. In the particular scenario, their is no fusion of gametes  and this form of reproduction is not sexual.

How many atoms are in 35 grams of table salt
Slav-nsk [51]
Adopting the number of avogrado 6.02 * 10²³ / mol 
<span>Sodium chloride (table salt)</span> Molar Mass = 58.44 g / mol 
We will first have to find the number of moles in 35 grams of the element, like this: 
 
1 mol ----------------- 58.44 g 
X ---------------------- 35 g 
 
58.44 * x = 35 * 1 
58.44x = 35 
X = \frac{35}{58.44}
X = 0.598904...
X ≈ 0.60<span> mol </span>
 
Now we will find how many atoms there are in 0.60 mol of this element, like this: 
 
1 mol -------------------- 6.02 * 10²³ atoms 
0.60 mol ----------------- X 
 
X = 0.60 * 6.02 * 10²³ 
\boxed{\boxed{x \approx 3.612 * 10^{23}\:atoms}}\end{array}}\qquad\quad\checkmark

Adenine (a) pairs with a: cytosine (c) B: Guanine (g) C: Thymine (T)
Artist 52 [7]
Adenine pairs with Thymine and Guanine pairs with Cytosine. I remember this by the car (C) goes in the garage (G). Then A and T are the only ones left, so they pair together.

What mass of ice can be melted with the same quantity of heat as required to raise the temperature of 3.00 mol H2O(l) by 50.0°C?
lions [1.4K]

Answer:

m=33.9g

Explanation:

Hello,

In this case, we can first compute the heat required for such temperature increase, considering the molar heat capacity of water (75.38 J/mol°C):

Q=nCp \Delta T=3.00mol*75.38\frac{J}{mol\°C} *50.0\°C\\\\Q=11307J

Afterwards, the mass of ice that can be melted is computed by:

Q=n \Delta _{fus}H

So we solve for moles with the proper units handling:

n=\frac{Q}{\Delta _{fus}H} =\frac{11307J}{6010\frac{J}{mol} } =1.88mol

Finally, with the molar mass of water we compute the mass:

m=1.88mol*\frac{18g}{1mol}\\ \\m=33.9g

Best regards.
