Use the scale bar to determine the sizes of a mature parent yeast cell and a cell budding from it. You will then calculate the v
Licemer1 [7]

Answer: A mature parent cell is approximately 4 µm, while a budding cell is 3 µm. Since the shape of a yeast is a sphere, we can use the formula below:

V= (4/3)π.r³, considering that π=3,14 and r is for ratio of the sphere, which is half of it's diameter.

For a parent cell, the volume is: 33 µm³

For a budding cell, the volume is: 14 µm³

Since the<u> volume determines how much cytoplasm a cell has</u>, then a budding cell needs to grow the mature parent cell - its own current volume, so the result would be 19 µm³ of cytoplasm.

To calculate the surface area, we use another formula that is presented below:

A= 4.π.r²

For a parent mature cell, the surface is 50 µm²

For a budding cell, the surface is 28 µm²

Since the <u>surface determines how much plasma membrane a cell has</u>, to know how much the budding cell needs to grow up to a mature state is simply using the surface area of the parent cell - the current surface area of it, resulting in 22  µm².

Describe the specific mechanisms of enzyme function​
zmey [24]
An enzyme attracts substrates to its active site, catalyzes the chemical reaction by which products are formed, and then allows the products to dissociate (separate from the enzyme surface).

What does laforin do normally? and why does the shape make it do what it does
Dennis_Churaev [7]
Laforin is mutated in patients with Lafora disease. 

I'm not sure about this but the shape helps it adapt to the human body.

A flower is ready to become a fruit where would the instruction be found? A. Nucleus B. Plant ovum C. Mitochondria D. Ribosomes
Feliz [49]
I am pretty sure it is Nucleus because the definition of nucleus is "the central and most important part of an object, movement, or group, forming the basis for its activity and growth." I hope this helps! Sorry if I am wrong. but a tip is look up what the definitions are and compare to see which fits best:)

If you could absorb another organism and take on its trait, what would it be? How and why would this new trait help you survive?
adell [148]
More strength and more physical abilities. I am not very active and very lazy a lot. It’s really hard to get out of bed and I don’t really like sports or anything physically active.
