Being able to respond to change (irritability) is one of the necessary life functions. Which body system is mostly responsible for this function

Answers

Answer:

The correct answer is : nervous system.

Explanation:

Irritability is one of the key aspect life which is deal with being able to response or change according to the stimuli that is occur and disturbs the homeostasis of the body which is maintaining the body environment for living.

Nervous system is deal with the irritability by sensing the stimuli in which change occur it can be physical stimuli such as temperature, light, or sound or chemical stimuli such as pH, ions, amount of required chemical or biological stimuli such microbes in body. All these stimuli are sense b the sensory neurons and then send these signals to brain or spinal cord in order t act and respond accordingly to maintain homeostasis.

Thus, the correct answer is : nervous sytem.

What would make the results of this experiment reliable?

Answers

HOPEFULLY THIS HELPS

THE ANSWER IS

When a scientist repeats an experiment with a different group of people or a different batch of the same chemicals and gets very similar results then those results are said to be reliable. Reliability is measured by a percentage – if you get exactly the same results every time then they are 100% reliable.

Explain how the turtle’s evolutionary process evolved the function of turtles shells?

Answers

Answer:

The explanation for the turtle's evolutionary process was quite a challenging one for evolutionists.

Two categories of paradigms have come to offer their ideas about how they think the turtle came about its amour.

Palaeontologists (that is, those who examine and report on the history of life here on earth using fossil records) state that the turtle's shell developed into what it is now over time from bony scales same as those which can be found on armadilloes and crocodiles.

Development biologists have a  very different opinion. They theorize that the shell evolved out of ribs. The ribs, according to them due to the need for environmental adaptation, became wider, and flatter and eventually merged to form shells.

Answer: b

Explanation:b

Answer: A

Explanation:

Modeling usually involves a simulation to make some kind of prediction or comparison. Genetic engineering involves changing the genetic makeup of an organism. Genomics is a new field dealing with gene mapping. The use of quinine for medicinal purposes is an early form of biotechnology. Four hundred years ago they were not mapping the genes of the cinchona tree.

If you pumped contaminated water from an aquifer, cleaned the water and pumped it back in what would happen?

Question 2 options:

The water would be re-contaminated by rock and soil in the aquifer

The water would clean the aquifer

It’s impossible to know what would happen

The water would be clean and stay clean

Answers

Answer:

It’s impossible to know what would happen

Explanation:

If contaminated water is pumped form an aquifer, cleaned and pumped back, it would be impossible to know what would happen unless the source of the contaminant is known.

If the source of the contaminant is known and removed before the water is pumped back into the acquifer, the water would be clean and stay clean provided that all the water was initially pumped off. If the source of the contaminant is not known, it would be difficult to predict what would happen.

A scientist conducted an investigation about the effects of diet on disease resistance in mice and made surprising observations. The mice with a genetic ear mutation seemed to show similar patterns of resistance compared to mice with normal ears. Based on this information, what will the scientist most likely do next?

Answers

Explanation:

When there is alteration in the DNA sequence in the chromosomes of an organisms which affects the protein expression and therefore the organism involved,the genetic condition is called mutation. its effects can be positive or negative,But,negative effects is most common.

It can be germline in which the genes is affected,or somatic in which the protein expression of the body cell is affected.

Answer:

The fact that the mice with genetic mutation shows similar patterns of inheritance show that some genes in the mice might be playing a dominant role in  diseases resistance in this animals.This is evident since the patterns were peculiar to  mice with mutated ears,and not observed in normal ears.

Therefore the experiment should be carried out again to confirm the influence of these genes on the resistance

Thank you

Amino acids is to protein as nucleotides is to nucleic acid.

What is the composition of nucleic acid ?

Nucleic acids are biomolecule major component of cell which carry genetic material, these are up two types of nucleic acid such as deoxy ribose nucleic acid or DNA  and ribonucleic acid or RNA.

DNA is the carrier of the genetic material which is passed from the parents to offspring and nucleic acids are composed of the monomers of nucleotides, these nucleotides are composed of nitrogenous base, phosphate and pentose sugar.

The nitrogenous bases are uracil, cytosine, thymine, adenine, and guanine, pentose sugar such as ribose sugar and deoxyribose sugar and phosphate group.

DNA contains thymine instead of uracil which is present in RNA; Adenine and guanine are the purines  having double ring structure while the rest are pyrimidines have a single ring structure. The phosphate group is negatively charged.

Answers

Answer:

- Scientific experiments are not falsifiable.

- Scientific experiments are peer-reviewed.

- Scientific hypotheses are testable

Explanation:

The scientific method refers to the process of examination of scientific hypotheses. This method is rigorous and requires 1-to raise questions about an observed phenomenon, 2-to produce an experiment and 3-to confirm this hypothesis by analyzing the results. The last step of scientific research is the peer review process, where independent researchers (usually 2-3 researchers) review the observed evidence in order to confirm or reject the results obtained from the experimentation. This hypothesis must also be testable, ie, it is imperative that it can be confirmed in further experiments.
