Solar energy is a clean, renewable energy source. Once a solar plant is built there is no fuel cost only maintenance. Why does s

olar energy not play a bigger role in energy production today?
A) The technology to make solar energy is not yet available.
B) Environmental groups are against solar energy as a power source.
C) The cost of maintenance still is more expensive then all other energy technologies.
D) The original cost of a solar plant still takes too long to be recovered by future savings.

Solar energy technology is currently very expensive, but it is completely renewable and non-polluting. New advances in technology will hopefully make it cheaper in the future.

if a cell increases the activity of its actin severing proteins, will it lead in the short term to more or less actin polymer ma
marta [7]

More polymer will form if the concentration of free actin monomers is higher than the Cc at both the plus and minus ends.

Less polymer will form if the concentration of free actin monomers is lower than the Cc at both the plus and minus ends.

Actin polymerization encourages FAK and Src to activate small G proteins by signalling to GEFs and GTPases (e.g., Rho and Rac). The actomyosin network is then forced to develop as a result of G proteins' induction of cytoskeleton-regulating proteins.

What stops cells from forming actin polymers?

Actin monomer is sequestered by monomer-binding proteins, reducing its availability for polymerization. As a result, actin does not polymerize when monomer-binding proteins are present in stoichiometric levels.

Q. If a cell increases the activity of its actin severing proteins, will it lead in the short term to MORE or LESS actin polymer mass? Chose the most accurate answer.

Increased severing activity will result in LESS polymer under any conditions.

Increased severing activity will result in NO CHANGE in the total amount of polymer under any conditions. It simply results in a larger number of smaller filaments.

Increased severing activity will result in MORE polymer under any conditions.

If the concentration of free actin monomers is below the Cc for both the plus and minus ends, then MORE polymer will result. If the concentration of free actin monomers is above the Cc for both the plus and minus ends, then LESS polymer will result.

If the concentration of free actin monomers is above the Cc for both the plus and minus ends, then MORE polymer will result. If the concentration of free actin monomers is below the Cc for both the plus and minus ends, then LESS polymer will result.

If you sorted 200 flies by eye color and body color, how many whole flies out of that 200 would you expect to exhibit each of th
mafiozo [28]

9:3:3:1 is the ratio.

From the given data,

We have a 9.8 two, ratio since we have 49/5, 15/5, 18/5, and 5/5.

This ratio resembles nine a little bit, which is what we inferred from the opposition's score.

When the two relevant genes exhibit independent assortment, this is the result. Therefore, the chromosomes/genes are not connected.

We are finally getting a ratio of 9:3:3:1

In flies, two possible outcomes for the body color phenotype is black and brown.

Whereas in eye color we have white eye and red eye.

Here, white eye is recessive and red eye is dominant

<h3>What does the independent assortment law entail? </h3>
  • According to Mendel's law of independent assortment, the alleles of two or more distinct genes are independently selected into gametes.
  • In other words, an allele for one gene does not affect the allele for another gene that a gamete acquires.

<h3>Where can I find independent assortment?</h3>
  • Meiosis I of gamete production, when homologous pairs line up in random orientations at the center of the cell as they prepare to split, provides the physical foundation for the law of independent assortment.
