Answer:

The given blank can be filled with histones.

Explanation:

The family of basic proteins, which associate with the DNA in the nucleus and assist in condensing it into chromatin are known as histones. The nuclear DNA does not come in the form of free linear strands, it is heavily condensed and enveloped around the histones so that to get fit within the nucleus and take part in the generation of chromosomes.  

These are the basic proteins, and because of their positive charge, they get associated with the DNA. Under the microscope, chromatin appears like beads on a string. The beads are known as nucleosomes. Each nucleosome comprises DNA wrapped around the 8 histone proteins, which works like a spool and is known as a histone octamer.

Answer:

hmmmm MARK ME BRAINLIST

Explanation I think Characteristics of ATP. Adenosine triphosphate (ATP) is an essential aspect to life, as it is the basic source of energy for all known living cells. ATP serves a dual function: it is individually a source of energy, as well as being involved in processes that release more energy when it is broken down to form adenosine diphosphate (ADP).

You will receive a set of ten quantitative values for each of three genotypes: aa, Aa, and AA.
miskamm [114]

Mean for the <u>Geno Code 0</u> is average of those ten values ((-3.97)+(-3.99) +(-5.55)+ (-4.56) + (-4.51) + (-4.2 )+( -4.95) + (-4.56) + (-4 )+ (-5.68))/10= -4.597

Standard deviation formula is √((-3.97- (-4.597)2 )+(-3.99-(-4.597)2) +(-5.55-(-4.597)2)+ (-4.56-(-4.597)2) + (-4.51-(-4.597)2) + (-4.2-(-4.597) 2 )+( -4.95-(-4.597)2) + (-4.56-(-4.597)2) + (-4 -(-4.597)2)+ (-5.68-(-4.597)2))/10= √  (0.39+0.37+0.91+0.001+0.007+0.16+0.12+0.001+0.36+1.17)/10= √0.3489=0.59

Mean for the <u>Geno 1 </u>is -0.25 (calculated on the same way as for Geno 0 with different numbers)  and standard deviation for Geno 1 is 0.65.

Mean for <u>Geno 2</u> is 5.241 and standard deviation is 1.038.

2.

If individual Phenotype_Value is 5.11, the corresponding genotype code is Geno code 2 since the value is in the range of values 5.241+- 1.

If individual Phenotype_Value is 5.03 the corresponding genotype code is also Geno code 2.

Since the standard deviation is used to measure the variation (dispersal) of set of data values (how close the values are to the mean value) we can conclude whether are random value is within a certain range.

Single-celled Paramecium live in pond water (a hypotonic environment relative to the cytosol). They have a structural feature, a
mylen [45]

Answer:

The correct answer is option A) "0.0 mM sucrose".

Explanation:

Since single-celled Paramecium use their contractile vacuole to osmoregulate upon hypotonic environments, it is expected that a condition where no sucrose or salt is added is the condition where the contractile vacuole would be most active. In this extremely hypotonic condition cells tend to absorb high quantities of water, the contractile vacuole pumps water out of the cell to regulate its osmotic pressure.
