Answer:

Length of the real cells = 7500 cm

Explanation:

A scale model is a physical representation of an object that has the same aspects as that of the object.

A scale model can be used in fields like engineering, film making,  salesmanship, etc

Length of the student's cell model = 15 cm

The scale is 1:500

So,

Length of the student's cell model / Length of the real cells  = 1:500

15 / Length of the real cells  = 1:500

Length of the real cells  = 15 × 500 = 7500 cm

Which accurately describes gymnosperms? Check all that apply. Some of them lose their leaves in winter.Some of them lack seeds.S
AleksandrR [38]
I think that correct answers are:
<span>Some of them lose their leaves in winter. (i.e. <span><em>Larix</em></span>)</span>
<span>They include the tallest plants (i.e<em>.Sequoia)

</em>I don't think they are the oldest type of seed plants, since in the past the classes like progymnosperms and seed ferns existed prior to the gymnosperms. But question isn't absolutely clear to me and I can't be 100% sure.
All of the gymnosperms have seeds unless human grows some seedless variant.
Gymnosperms don't have flowers like angiosperms do, but some people think that cone is kind of flower.
Male cones produce pollen, not female.
Hope I helped :)

lapo4ka [179]

Answer:

Yes, I think this scheme can work. The chippings will provide enough ethanol to power the mower. The mover requires up to 15% ethanol. As he is distilling it to 95% ethanol, it would be more than enough for the mower to work. And also he can use the remaining ethanol for other purposes like powering Joe’s car or to create alcoholic beverages to drink when Joe’s friends come over to watch UCLA football games on Saturday afternoons.
