Biomass is the most used renewable source of energy in US in the year of 2009.

<h3><u>Explanation:</u></h3>

In US, the country is very cold and use of wood and other plant products as chimney fuels, or in cooking and other purposes are very common. This is because being a temperate country, US has forests of conifers which are source of soft wood, ideal for burning.

Other sources of Biomass energy comes from the biogas, wood wastes, ethanol, municipal solid wastes and even biodiesel.

As a present day scenario, although coal and petroleum are still the most used fuels in US, but the use of renewable sources of energy has increased to twice the amount from 2010 to 2018.

Higher-order folding involves association of the dna with a nuclear _____, which contains large amounts of _____ and _____.

Sonja [21]

Higher-order folding involves association of the DNA with a nuclear scaffold, which contains large amounts of Histone H1 and Topoisomerase II.

<h3>What is Histone?</h3>

Histones are highly basic proteins abundant in lysine and arginine residues that provides structural support for a chromosome. They are found in eukaryotic cell nuclei. They act as spools around which DNA winds, which gives the chromosome a more compact shape, to create structural units called nucleosomes. Nucleosomes in turn are wrapped as 30-nanometer fibers that form tightly packed chromatin. There are five types of histones namely H2A, H2B, H3, H4 and H1 linker histone. Within a nucleosome, they exist as two dimers of (H2A-H2B) and a complex of (H32-H42) eventually forming an octamer.

<h3>What is Topoisomerases?</h3>

Topoisomerases are nuclear enzymes which play essential roles in DNA replication, transcription, chromosome segregation, and recombination.

Describe how increasing salinity affects the amount of fluid ejected each time a contractile vacuole contracts. Calculate the wa

Mandarinka [93]

Answer:

Water potential $= -2$

Explanation:

As we know,

Water potential is equal to the sum of pressure potential and solute potential

Ψ $=$ ΨS $+$ ΨP

Where Ψ is the water potential

ΨS is the solute potential

ΨP is the pressure potential

Given -

Solute potential ( ΨS ) $= -2$

Pressure potential ( ΨP ) $= 0$

Substituting the given values, we get -

Ψ $=$ $- 2 + 0$

Ψ $=$ $- 2$

If a mutation in UASg prevents Gal4 from binding, a possible consequence is:

bekas [8.4K]

Answer:

Option B.

Transcription will be silenced.

Explanation:

Gal4 is a transcription factor that regulate gene expression in a positive way. It is a year protein that regulates gene induced by galactose. It lies upstream of the activating sequence and activate them. It binds to 17 basepair sites of the upstream activating sequence(UAS). If USAg prevents Gal4 from binding, transcription will be silenced.
