which classification groups have linear chromosomeswhich classification groups have linear chromosomes
Until recently, prokaryotes did not contain linear plasmids or chromosomes, but they have since been discovered in spirochaetes, Gram-positive bacteria, and Gram-negative bacteria. Bacterial linear DNA has been classified into two structural kinds. Each end of linear plasmids from the spirochaete Borrelia has a covalently closed hairpin loop, while each end of linear plasmids from the Gram-positive filamentous Streptomyces has a covalently connected protein. In eukaryotic cells, replicons with comparable structures are more common than in prokaryotes. However, linear genomic architectures are likely more widespread in bacteria than previously thought, and some replicons may be able to switch between circular and linear isomers. The molecular biology of these widely scattered pieces reveals information about the origins of linear DNA in bacteria, including evidence of prokaryote-eukaryotes genetic exchange.
What is a scatter pattern? What can it tell a forensic anthropologist?
Answer:
A scatter plot (aka scatter chart, scatter graph) uses dots to represent values for two different numeric variables. The position of each dot on the horizontal and vertical axis indicates values for an individual data point. Scatter plots are used to observe relationships between variables.

No fake answers and no links. Why do astronomers rely on different types of telescopes?
Answer:
Because different telescopes are used to study and observe different types of objects in space.
Explanation:
They need many different types of telescopes to look at space because each telescope shows them different things. Light comes in wavelengths from short to long. Even though all light is fundamentally the same thing, the way that astronomers observe light depends on the portion of the spectrum they wish to study. And it also depends on the telescope itself.
how so different biogeographical zones affect agricultural practice?
Answer:
Biodiversity within a given ecosystem will be affected by a number of biogeographic factors: Larger habitats tend to promote biodiversity better than smaller habitats (more available niches = less competition) Ecology at the edges of ecosystems is different from central areas (e.g. more sunlight, more wind,

Transfusing mismatched blood types is a problem for a patient because A. it slows down digestion. B. it changes blood composition. C. it causes infection. D. it causes clots in blood vessels.
Answer:
D. it causes clots in blood vessels.
Explanation:
If you receive blood that is not compatible with your blood, your body produces antibodies to destroy the donor's blood cells. This process causes the transfusion reaction. Blood that you receive in a transfusion must be compatible with your own blood.

During a Vo2max test, many people have a Respiratory Exchange Ratio greater than 1.0 as they approach their VO2max. Why
The important of RER between 0.7 and 1 shows a blend of carbohydrates and fat as a basis of energy. In case the value is more significant than 1, it means anaerobic respiration as a result of more carbon dioxide being developed than the oxygen that is being consumed.
What is the difference between vo2max and relative vo2max?Absolute VO2 max is only the amount of oxygen you breathe in liters per minute.
This dose depends on your age, weight, size, and gender. Relative VO2 maximum Relative VO2 max calculates your weight in liters per minute per kilogram of body weight.
Thus, anaerobic respiration results of more carbon dioxide being forged than the oxygen that is being destroyed.

Which statement describes nuclear fission?
o the joining of two nuclei
o the use of neutrons to make energy
O the splitting of a nucleus
o the production of electricity from atoms
According to the the concept of nuclear reactions ,nuclear fission is the splitting of the nucleus.
What are nuclear reactions?
There are two types of nuclear reactions which are nuclear fusion and nuclear fission .They involve the combination and disintegration of the element's nucleus respectively.
In nuclear fission, the nucleus of the atom is bombarded with electrons of low energy which splits the nucleus in to two parts .Large amount of energy is released in the process.It is used in nuclear power reactors as it produces large amount of energy.
In nuclear fusion,on the other hand, is a reaction which occurs when two or more atoms combine to form a heavy nucleus.Large amount of energy is released in the process which is greater than that of the energy which is released in nuclear fission process.

Like other reflexes, sneezing involves a reflex arc,
Sneezing is triggered when the nerve endings in

dust or an unusual smell. Nerves carry these
impulses to the sneezing center in the brain stem
The sneezing center sends instructions to the
facial nerves that lead to the lungs and

Answer:
C. Individuals with thicker fur had a survival advantage in the cold, allowing these individuals to reproduce moe often and create more offspring.
Explanation:
Natural selection means the process of changing the adapting the new environment. Based on the given data one can conclude that the individual with thicker fur had a survival advantage in the cold environment.
Why natural selection occurs?
Natural selection takes place due to 3 underlying reasons:
Reproduction
Heredity
Variation in fitness of organisms.
Due to these reasons, natural selection can leads to speciation.
As the individual are living in cold environment, they need to adapt the change in environment. So, individuals with thicker fur had a survival advantage in the cold environment, allowing these individuals to reproduce more often and create more offsprings.
Thus, option C is correct.

What is the correct sentence?
Genes code for proteins, and proteins code for traits.
Proteins code for genes, which code for traits.
Traits code for genes, and genes code for proteins.
Answer: The correct sequence in the expression of a trait is gene > protein > trait (Option B).
Explanation:
During gene transcription, a linear fragment of DNA referred to as a 'gene' is used as template to synthesize a complementary messenger RNA (mRNA) sequence.
Subsequently, this mRNA is then used as template to create a protein by a process called translation.
Moreover, phenotypic traits can be defined as all observable characteristics that an organism has.
The phenotypic traits are largely determined by the expression of either enzymatic or structural proteins, which interact to shape the phenotype of an organism.
In conclusion, the correct sequence in the expression of a trait is gene > protein > trait (Option B).
Answer:
Genes code for proteins, and proteins code for traits.
Explanation:
Simplified Response:
Genes direct the synthesis of RNA through transcription and translation. Through these processes, proteins are assembled. These proteins form the structures and functions that make up all living organisms. And therefore, these proteins are responsible for the traits of living organisms as well.
So, that's why the correct choice would be the first option.

This is the correct sequence of events of the cardiac cycle.
Given what we know we can confirm that the correct sequence of events for the cardiac cycle is atrial systole, ventricular systole, atrial diastole and ventricular diastole.
What is the cardiac cycle?The cardiac cycle is what we define as the cycle in which the heart beats. This cycle begins with the systole of both the atria and the ventricles, in which they contract, first the atria, then the ventricle. This is to pump blood into the next part of the circulatory tract. This is followed by the diastole of each cavity, in which they fill with blood once more.
Therefore, we can confirm that the correct sequence of events for the cardiac cycle is atrial systole, ventricular systole, atrial diastole, and ventricular diastole.

6. How did natural selection work in the red-eye frog egg hatching?
7. What was the explanation regarding the phenotypic plasticity of the red-eye frog eggs?
We can confirm that natural selection resulted in the coloration of the red-eye frog due to its higher chance of survival with this change in pigment.
Why would this color help the frog survive?Bright pigments are a common defense mechanism in nature. Organisms that are poisonous often evolve bright coloration as a warning to predators. Over time, natural selection ensures that the organisms who've successfully incorporated this pigmentation have much higher survival rates and therefore the species entirely evolves into possessing this trait, as was the case with the red-eye frog.
Therefore, we can confirm that natural selection resulted in the bright pigmentation of the red-eye frog because of the much higher survival rate that this adaptation afforded the organism.
