A circular double-stranded DNA molecule contains 4200 base pairs. In solution, DNA is in a B-form helix, with about 10.5 base pairs/turn. The DNA has 12 superhelical turns. What is its superhelix density
Answer:
The correct answer is - 3 × 10⁻²
Explanation:
first find LKo = length of BDNA/ 10.5 bp/turn
= 4200/10.5
= 400
now calculate Δ LK= LK - LKo
ΔLK = 412-400
ΔLK = 12
now, superhelix density = ΔLK/LKo
⇒ 12/400 = 0.03
= 3×10⁻²
Thus, the correct answer is - 3 × 10⁻²

Jessica weighs 125 pounds. She rode a bike at 17mph for 25 minutes. What is the calorie cost of this activity?
a. 185 calories
b. 178 calories
c. 180 calories
d. 190 calories
e. 188 calories
Answer:
b. 178 calories
ok so 17mph is 0.57 weight/min
so what were going to do is multiply 125 times 0.57 which is 7.125
then multiple that answer by 25 mintues: 7.125 x 25 = 178.12...etc
now if we round this up it stays as 178!
Which structure of a paramecium is analogous to a “reserve copy” of all the cell’s genes
Answer:
micro nucleus
Explanation:
Huntington's disease, which causes degeneration of neurons, runs in Mark's family. Huntington's is a heritable autosomal dominant genetic disease, in an autosomal dominant disease, only one abnormal allele is required to cause the disease in offspring. However, it is possible not all offspring will receive the abnormal allele from an affected heterozygous parent.
Family members that have the disease include Mark's maternal grandfather and Mark's maternal aunts. Mark's maternal grandmother does not have the disease.
Because symptoms of Huntington's disease do not appear until later in life, genetic testing is necessary to determine whether a younger individual possesses the allele for the disease. These tests determined that Mark's mother does not carry the allele for Huntington's disease.
Mark's paternal aunt suggested that Mark create a pedigree to track the disease in his family. Use the symbols provided to complete the pedigree. Each symbol may be used more than once.
Answer:
As it is given that Mark's paternal grandmother and grandfather does not carry the disease. The symbols on the right side of the Punnett represent Mark's paternal family. If both his paternal grandparents are unaffected then his father and paternal aunt are also not affected by the disease.
His maternal grandfather is affected as mentioned and also his maternal aunts are affected. Mark's mother is unaffected as she does not have the disease-causing alleles determined by genetic testing.
Both of the marks parents are unaffected which indicates that marks also do not carry the allele of the disease.
Huntington's disease is an autosomal dominant disorder in which the presence of even one dominant allele can cause the disorder.
The autosomal disorder can not skip a generation, have to be present in every generation.
Condition Given:
Affected Member: Mark's Maternal grandfather and Maternal aunts.
Normal: Mark's Maternal grandmother and Mark's Mother.
As MArk's Maternal Grandfather is affected then his genotype must be Aa because Mark's Maternal grandmother is unaffected (aa), this is the only condition where Mark's mother will be normal.
A- Dominant (Huntington)
a- Recessive
Maternal means on the mother's side and paternal means on the father's side.
The diagram is attached below.
I-1: Mark's maternal Grandmother
I-2: Mark's maternal Grandfather
I-3&4: Mark's Paternal Grandparents
II-1&2: Mark's Maternal aunts
II-5: Mark's paternal aunt
II-3&4: Mark's mother and father respectively will not have the disease as both father and mother of Mark are normal.

A student recorded the height of each student in the school. She then made a bar graph of her results. She observed that
the results form a bell-shaped curve. The student could use her graph as evidence to support which argument?
Height is affected by multiple pairs of genes on different chromosomes.
The alleles for tall height and short height are codominant.
The allele for being tall is dominant to the allele for shorter heights.
There are three alleles for height that demonstrate incomplete dominance.
Answer:
Height is affected by multiple pairs of genes on different chromosomes.
Explanation:
The height is a quantitative trait, it is a phenotypic feature that presents a continuous range of variation in the population. The cumulative effects of many genes and the environment produce a normal distribution bell-shaped curve when they are drawn, this being a characteristic of quantitative genetic traits. Examples of quantitative traits include, among others, height, metabolic rate and weight.
The student could use their graph as evidence to support the argument that "The alleles for tall stature and short stature are codominant."
What is a Codominant gene?Codominant: Autosomal codominant inheritance is the condition in which the heterozygote has the characteristics determined by both alleles (dominant and recessive).
What is allele?Allele genes are those that occupy the same locus on homlogous chromosomes and are involved in determining the same character.
With this information, we can conclude that the genes alleles of the students in this class are codominant.

what is a part of interphase A. cytokinesis B. telophase C. anaphase D. s phase
Answer:
D
Explanation:
I did it on my own soci know it's the answer
In the context of interphase, the S phase is the specific part where DNA replication occurs, contributing to the overall process of cell division and ensuring the transmission of genetic material to new cells and the correct option is option D.
Interphase is the longest phase of the cell cycle, and it is divided into three main stages: G1 phase, S phase, and G2 phase. Among these stages, the S phase is specifically responsible for DNA replication. It is during the S phase that the cell's DNA is duplicated in order to prepare for cell division.
During the S phase, the DNA helix unwinds, and the two strands separate. Enzymes and proteins then work together to synthesize new complementary strands for each of the separated DNA strands. As a result, two identical copies of the DNA molecule are produced.
The S phase plays a crucial role in maintaining the genetic integrity of the cell. By accurately duplicating the DNA, the cell ensures that each daughter cell formed during cell division receives an identical set of genetic information. This is vital for the proper functioning and development of organisms.
Thus, the ideal selection is option D.

The Law of Overcompensation and Overload allows for which of the following in regards to intensity?
A. Progressively increase over a period to time
B. Progressively decrease over a period of time
C. Remain the same
D. Acute decrease over a period of time
Answer:
A. Progressively increase over a period to time
Explanation:
The law of overcompensation states that the environment compensates for any factor by twice the amount and the overload theory states that challenges should be increased while working on a certain task to improve the results.
The laws allow for the following:
Option A. Progressively increase over some time.
The laws can be explained as:
In fitness and sports, the laws of overload and overcompensation are widely used. The overload principle says that the intensity and exercise duration should be increased gradually to see an improvement in endurance, strength and muscles.According to the overcompensation theory, the body recovers from any injury or harm the body does not quit there and will be stronger compared to before.Thus, overcompensation and overload increase over time.

The graph below shows the temperature of ocean water at different depths. Which part of the graph represents the thermocline? a. AB b. BC c. CD d. DE
Answer:
C
Explanation:
Generally temperature changes rapidly with the dept in aquatic bodies especially the oceans.The thin distinct or transition layer where the variation in temperature with depth is most significant is called Thermocline.
Its represents the gaps which separate the upper mixed layer from the lower deeper water bed below,it therefore represent the layer of mixture of the upper surface warmer water (C) below 200 meters, with the cooler water layer(E) below,from 1000 meters check the attachment.
It is caused by variation in intensity of sunlight.The latter hits the surface water layer and therefore raises the temperature.But,because of decrease in sunlight penetration,with increasing dept, the temperature of the lower water dept decreases.
