Implanting an electrode that supplies a weak electrical current to specific brain areas is called _____. It is useful in the treatment of _____
Answer:
Deep Brain Stimulation (DBS)
Depression, Uncoordinated body movements such as in Parkinson's disease
Explanation:
Deep brain stimulation is a surgical procedure in which a device that sends electrical impulses to the brain by means of lead wires connected to electrodes placed in the specific areas of the brain, is implanted in the body, typically the chest region.
This surgical procedure is usually required to treat diseases in which there is irregular and improper nervous stimulation of the brain resulting in various nervous disorders such as irregular muscle movements as in Parkinson's disease as well as depression.
The impulses sent from the stimulator device to the electrodes in the brain through the wires, serves to stabilize and normalize nerve signals sent to the brain.

11) Assume a population of deer has a crude birth rate of 26 per 1,000/yr, a crude death rate of 15 per 1,000/yr, an immigration rate of 7 per 1,000/yr, and a emigration rate of 9 per 1,000/yr. What is the population growth rate
Answer:
9 per 1,000/yr.
Explanation:
The population growth rate is 9 per 1,000/yr.
The rate of growth of population is determined by the following formula:
Growth rate = B - D + I - E
Where B = birth rate, D = death rate, I = immigration, and E = emigration
In this case, B = 26, D = 15, I = 7, and E = 9. Substitute these values into the equation of growth rate.
Growth rate = (26 - 15) + (7 - 9)
= 11 - 2 = 9
Hence, the growth rate of the deer's population is 9 per 1,000/yr.

Answer:
knowledge and valuable resources are shared among scientists
Explanation:
The best benefit and reason for joining a membership in a research community is that knowledge and valuable resources are shared among scientists. Since the entire community is working towards a common goal, then gaining information from everyone in order to get closer to that goal is priceless. Also, the ability to use high-end resources that would be impossible to use as a lone scientist due to its high price is also a very valuable benefit.
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
Explain what are co-evolved mutations and how can they help with predicting protein structures?
Answer:
The correct answer is as follows.
Explanation:
Coevolution is a phenomena where two related species evolve at the same time since they share a close relation. For instance, the relation between a predator as its prey or a virus and its hostage. This phenomena helps to predict protein structures, since by revealing the higher order structure of a protein we can predict the structure of other protein that have coevolved with it. This has been used in several studies, such as one 2015 study of Pandini and collaborators entitled "Coevolved Mutations Reveal Distinct Architectures for Two Core Proteins in the Bacterial Flagellar Motor".

-Diffusion describes the concentration gradient in a solution.
-Diffusion regulates which molecules can and can't pass through a plasma membrane.
-Diffusion is the movement of water across a selectively permeable membrane.
-Diffusion does not require energy and is therefore a form of passive transport.
Answer:
Diffusion is the movement of water across a selectively permeable membrane.
Explanation:
Hope it helps.
The statement which is true about diffusion is as follows:
Diffusion does not require energy and is therefore a form of passive transport.Thus, the correct option is D.
What is Diffusion?Diffusion may be defined as the movement of substances from a region of higher concentration gradient to a region of lower concentration gradient through a semipermeable membrane.
Diffusion not only facilitated the movement of water across a selectively permeable membrane but also other substances as well. Diffusion only regulates the movement of those molecules which can pass through a plasma membrane.
It is the means of movement of substances that do not require any form of energy. And thus, diffusion is significantly a form of passive transport.
Therefore, the correct option for this question is D.

The study of changes in phenotype that are not related to changes in the DNA and that may result from the interaction between the genotype and the environment:
Answer:
Epigenetics.
Explanation:
Epigenetics is the study of phenotypic changes which are heritable but not related to changes in the DNA sequence. It is influenced by several factors including the environment.
An example of epigenetics is DNA methylation: addition of methyl group to some part of the DNA that prevents that part from being expressed. Other examples include history modifications.
In summary, Epigenetics describes inheritance through other mechanisms than through the DNA sequence.

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.

If autophosphorylation of CheA protein does not occur, then Escherichia coli cells must be _________.
Options are no given in the question. The complete question is as follows:
If autophosphorylation of CheA protein does not occur, then Escherichia coli cells must be_________________.
A. in a gradient of a chemoattractant.
B. in a gradient of a chemorepellant.
C. tumbling.
D. rotating flagella clockwise.
Answer:
A. in a gradient of a chemoattractant
Explanation:
The autophosphorylation of CheA is described as the autophosphorylation of histidine kinase (s) (CheA protein) in the presence of MgCl 2 and ATP.
If autophosphorylation of CheA protein does not occur in Escherichia coli, then the cells of E.Coli undergo methylation events that allow cell in a gradient of chemoattractants which increases the activity of CheA and CheY-P and cells adapt according to the concentration of chemoattractant.
Hence, the correct answer is A.
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
