What does a chromosome consist of?
A. Tightly wound DNA only.
B. Loosely dispersed DNA and proteins.
C. Tightly wound DNA and proteins.
D. Loosely dispersed DNA.
Answer:
C
Explanation:
So, there are 2 different forms that DNA can be found in.
The more common form, where the DNA is loosly scattered.
There is a less common form, however, only found during cell division, which is a compacted form. The DNA is tighly wound in this case.
In the case of chromosomes, DNA is tightly pakced, and not loose.
Now, do they are do they not have protiens?
Well, heres another question, how does the DNA get compacted?
It has to wrap around histone protiens.
The logn strands of DNA wrap around many histone protiens, until the full length of DNA has been compacted.
So to answer the question, yes, there are protiens found in chromosomes(specificly histone).
This means the answer must be C, since chrosomes are both tightly bound, and contain protein.

Scientists have observed many close similarities in the DNA sequences of whales and dolphins. This observation is evidence of which idea?
Dolphins, porpoises, and whales all are in the group of marine animals known as cetaceans. Scientists saw many close similarities in the DNA sequences of whales and dolphins. This observation is proof of whales and dolphins both evolved from a relatively recent common ancestor.
What is cetaceans?Cetacean are members of an aquatic group of mammals commonly known as whales, dolphins, and porpoises.
The ancient Greeks stated that cetaceans can breathe air, give birth to live young, produce milk, and have hair. These are all features of mammals.
As the scientist observed the close similarities in the DNA sequences of both the whales and the dolphins. This shows the proof that whales and dolphins both evolved from a relatively recent common ancestor.
Thus, this is the evidence to reveal the reason behind the similarities in DNA sequences in whale and dolphin.

The rate at which the concentration of a drug in the bloodstream decreases is proportional to the concentration at any time t. Initially, the concentration of the drug in the bloodstream is C0 g/mL. What is the concentration of the drug in the bloodstream any time t
Answer:
[tex]C(t) = C_oe^{-kt}[/tex]
Explanation:
From the given information:
At any given time (t), let c(t) represent the concentration of the drug present in bloodstream.
Deriving the equation:
[tex]\dfrac{dC}{dt}[/tex] decrease proportionally to Concentration C
i.e
[tex]\dfrac{dc}{dt} \alpha - C[/tex]
[tex]\dfrac{dc}{dt} = -k C[/tex]
[tex]\dfrac{dc}{c} = -k dt[/tex]
[tex]\int \dfrac{dc}{c} = -k \int dt[/tex]
㏑(C) = -kt + λ
where,
λ is the integration constant.
Integrating at t = 0, concentration of blood = Co g/mL
C(0) = Co
㏑(C₀) = 0 + λ
λ = ㏑(C₀)
From ㏑(C) = -kt + λ
㏑(C) = -kt + ㏑C₀
㏑(C) - ㏑C₀ = -kt
[tex]\dfrac{C}{C_o} = e^{-kt}[/tex]
[tex]C(t) = C_oe^{-kt}[/tex]
∴
The concentration of drug in blood at any time t is:
[tex]C(t) = C_oe^{-kt}[/tex]

A partly full paint can has 2.75 liters of paint left in it. What is volume of the paint in cubic
centimeters?
(3)
A) 2.75 x 10-3 cm3
C) 275 x 10-3 cm3
E) 27.5 x 103 cm3
B)
2.75 cm
D)
2.75 x 103 cm
Answer:
2.75 x 10³ cm³
Explanation:
Volume can be measured in both liters (L) and cubic centimeters (cm³), however,
1 liter = 1000cm³
According to this question, a partly full paint has 2.75 liters of paint left in it.
Since 1 liter = 1000cm³
2.75 liters = 2.75 × 1000
2.75 × 10³ cm³ is left.

What is a way to prevent eutrophication?
Answer:
Agricultural fertilizers are one of the main human causes of eutrophication. Fertilizers, used in farming to make soil more fertile, contain nitrogen and phosphorus. The use, or overuse, of fertilizers can cause these nutrients to runoff of the farmer's field and enter waterways. Eutrophication can have serious effects, like algal blooms that block light from getting into the water and harm the plants and animals that need it. If there's enough overgrowth of algae, it can prevent oxygen from getting into the water, making it hypoxic and creating a dead zone where no organisms can survive.
The following is a list of methods that can be used to control eutrophication:
planting vegetation along streambeds to slow erosion and absorb nutrients.
controlling application amount and timing of fertilizer.
controlling runoff from feedlots.
The best, easiest, and most efficient way to prevent eutrophication is by preventing excess nutrients from reaching water bodies. This can be done in a number of ways, the simplest of which is just being aware of the chemicals and fertilizers that we are using.
Imagine the CCA added to the 3' end of the tRNA consisted of DNA nucleotides. It (WOULD/WOULD NOT) be possible to connect an amino acid to this tRNA. Explain.
Answer:
The correct answer is - it would because both DNA and RNA have 3' OH.
Explanation:
Ammino acid will connect to the tRNA due to the fact that the process of aminoacylation of tRNA when DNA nucleotide is used will perform or act same the mechanism of Class II aminoacyl tRNA synthetase as both DNA and tRNA have 3'OH. This will get the help of 3'OH in the CCA to bond with charged amino acid.
Thus, the correct answer would be - it would because both DNA and RNA have 3' OH.

How much stronger is a magnitude 8 earthquake than a magnitude 5 earthquake?
A. 1000
B. 30
C. 3
D. 10
Answer:
A. 1000
Explanation:
The Richter scale is a scale of numbers used to measure the magnitude of an earthquake, which is based on the size of its seismic waves. This scale indicates a number to quantify the total seismic energy released by an earthquake. The Richter magnitude scale is a base-10 logarithmic scale, thereby a difference of one (1) point in the scale of magnitude corresponds to a 10-fold increase in amplitude. For example, based on the Richter scale, a magnitude-8 earthquake is 100 times greater than a magnitude-6 and 1000 times greater in amplitude than a magnitude-5.
