The organelle controls cellular activity comparable to the way the brain controls body activity is cell membrane. Thus, option B is correct.
What is cell membrane?Cell membrane has been defined as the wall that differentiate and protect the inner structure of cell from the outer environment. The main function of the cell membrane has to keep away the toxic material out of the cell. The cell membrane contain channels as well as receptors that give permission to only selective permeable membrane to enter into the cell.
Tissue has been combined together and they form muscles and these muscles are of several types and after that muscles combined together and they form organ and each of the organ of the body has been made up of different types of tissue. Like heart has made up of such type of tissue that never takes rest.
At last the organs or we can say that two three organs combined together to form the organ system of the body such as nervous system, respiratory system, and these systems combinedly form the whole organism.
Therefore, The organelle controls cellular activity comparable to the way the brain controls body activity is cell membrane. Thus, option B is correct.

The surprisingly low rates of genetic differences between different current human populations (about only 6.5%) and that most genetic diversity occurs person-to-person within a population rather than population to population points to:
A.
a common origin of Homosapiens sapiens in Africa from a small number of people
B.
a fairly high rate of gene flow between human populations
C.
a fairly short time, perhaps 200,000 years existing as a new species in Africa
D.
all of the above
Answer:
the answer for this question would be B.
a fairly high rate of gene flow between human populations
Genetic diversity is the result of heritable traits that vary within species. It is seen more in person-person than in population because the human population has a high rate of gene flow. Thus, option B is correct.
What are gene flow and drift?Gene flow is the passing of the heritable traits outside and inside the population due to factors like migration or because of the gametes. The alleles possessing the characters are moved from one population to another.
In genetic drift, the allele frequency experiences an alteration in the genetic pool of the population. High genetic flow and the drift in humans result in genetic diversity. It causes very neutral differences to appear and are most likely to be seen in person rather than in the whole population.
Therefore, the high gene flow results in genetic diversity in the person.

Which of the following will most likely decrease genetic diversity?
А increased reproduction
B selective breeding
C mutations
D immigration
Selective breeding dangers reduced genetic diversity can result in certain insects or diseases attacking, which could be quite devastating. Thus, option B is correct.
What is the cause of selective breeding in genetic diversity?Selective breeding can contribute to a large reduction in the genetic diversity of farmed populations, endangering long-term evolutionary progress and limiting populations' ability to adjust to environmental changes.
Unknowingly selecting uncommon illness genes as part of a desirable characteristic might cause difficulties with particular organisms, such as the high prevalence of deafness in Dalmatian dogs.
Genetic diversity is typically reduced by selective breeding, since only a few individuals are employed to produce enormous numbers of offspring. The population's survivability may be impacted by this.
Therefore, selective breeding will most likely decrease genetic diversity.

Explain the difference between independent variables, dependent variables, and control variables.
Answer:
Independent: Purposely altered
Dependent: Changes with respect to the independent being altered
Controlled: Never changes
Explanation:
An independent variable is a variable in which does not rely on other pieces/variables of an experiment to assume a value. In other words, it does not change when other variables change. However, it can be changed intentionally by the scientist.
A dependent variable is a variable in which its change in value relies on other pieces/variables of an experiment to assume a value. So, if the indeoendent variable is changed, the dependent variable will change as well. The opposite is not true though - if the dependent variable changes (for whatever reason), the independent variable hasn't necessarily been changed.
A controlled variable is a variable that stays CONSTANT throughout an experiment. It is never changed, and nothing will change it. An example of a control variable is the number of participants in a study: no more participants are being added, and no participants are being removed. The number of participants remains STATIC throughout the study.
Duchenne Muscular Dystrophy (DMD) is a sex-linked trait that causes muscular weakness that gets worse as a person ages. Which is most likely true of Duchenne Muscular Dystrophy? A. DMD can only be inherited by females. B. Females with DMD always have a mother with DMD. C. The gene for DMD is located on the X or Y chromosome. D. The gene for DMD is most active in the cells of the reproductive organs.
Answer: C
Explanation:
DMD is s*x linked trait. This means that we have to consider the chromosomes XX and XY. For a male to have DMD, this means the mom must must pass down the allele for DMD. The mom can either be a carrier OR she has to have DMD and the dad can only pass down the Y chromosome. For a daughter to get DMD, this means the dad has to have the allele for DMD and so does the mom. That means that the dad has DMD and the mom can either have DMD or be a carrier. Based off of this logic, we know that the answer isn't B. Because they tell us DMD is s*x-linked trait, it means that the gene for DMD is on the x or y chromosome.

Bacteria are sensitive to certain antibiotics like chloramphenicol and streptomycin, which kill the bacteria by interfering with translation through mechanisms that affect the ribosome's ability to function. If a researcher were to culture populations of Archaea and then treat them with either of the previously mentioned antibiotics, what would be the predicted results
Answer:
Explanation:
Neither antibiotic will have an effect on Archaeon populations because their ribosomes are different from bacterial ribosomes.
The predicted result of this experiment is that Archaea do not show any response towards specific antibiotics.
What are Antibiotics?Antibiotics may be defined as a type of medication that inhibits the growth of microorganisms and fight against bacterial infections in humans or animals.
Due to the alterations in the structural and functional unit of ribosomes, none of the antibiotics causes any significant effect on the body of Archaea.

In eukaryotes transcription takes place in the _________. translation takes place in the ________.
1. cytoplasm/cytoplasm
2. nucleus/cytoplasm
3. nucleus/ribosomes
4. ribosomes/nucleus
Answer:
3
Explanation:
The correct answer will be option-Transcription takes place in the nucleus, and translation takes place in ribosomes.
The regulation of genes is regulated and controlled by two main processes of central dogma called transcription and translation.
Transcription is the process of formation of messenger RNA or mRNA from a single strand of DNA whereas translation is the formation of protein from mRNA.
This process takes place in different sites in prokaryotes and eukaryotes. In prokaryotes, both transcription and translation take place in the cytoplasm but in eukaryotes, the transcription takes place in the nucleus whereas translation takes place in the ribosomes present in the cytoplasm.
