Which question can be used to evaluate reliability of a source
Answers
Answer: The question can be used to evaluate the reliability of a source is Do these results support the author's own opinion?
In sources (books, articles, etc), reliability implies the information of a source can be trusted. This occurs if:
All the information is based on facts
The information is not manipulated by the author's opinion or interests
In this context, it is expected the information of the source is objective rather than influenced by the author's opinion. Therefore, one way to check the reliability of a source is "Do these results support the author's own opinion" because if the information is manipulated by a personal opinion, the source is not reliable.
Also, other questions are not appropriate because they are related to other aspects such as relevance, not reliability.
The answer as to which question can be used to evaluate the reliability of a source lies in the following options :
“Do these results support the author's own opinion?” “Is this data challenged by anyone in the public?” “Is this research relevant to me?” “Who was paid to do this research?”The correct answer would be “Do these results support the author's own opinion?”
First, the reliability of a source refers to the level of dependability or trustability of the source.That a data is challenged by someone in the public does not make it more or less dependable, all other things being equal.Who is paid to do a research has no bearing on the reliability of the outcome as long as the scientific method is followed to the core.However, if a result supports the opinion of the author of the result, this might call the reliability of the result into question.A result that reflects the opinion of its author might be scrutinized for confirmation bias. Hence, such a question can be sued to evaluate the reliability of a source.

which elements would react most easily with each other?
Answers
Answer:
an element with a high electronegativity and an element with a single valence electron
Explanation:
Answer:
The Correct answer would be an element with a high electronegativity and with a single valence electron.
Explanation:
Atoms need 8 electrons in their outershells to be stable. If they don't have eight, they will try to borrow from other atoms. So if an atom only needs one more electron, think of it as being desperate and highly reactive. When an atom with only one valence electron (electron in the outershell) comes along, it's the easiest victim to borrow off of.

7. Observations and inferences are
important in science. How would you
explain the difference between the
two words?
Answers
Hey there! I'm happy to help!
Observations are things that can be written down or described. You can observe something with any of your five senses: you can see what color something turns, you can hear the noise something makes, you can taste a cookie with a different amount of an ingredient, you can smell an odor produced by a chemical reaction, and you can feel the texture of different samples.
You can also create observations by using scientific tools. For example, instead of feeling if water is hot or cold, you could use a thermometer. This will give you numerical data which can be put into a table or graphed for further analyzing.
Inferences are created from observation. You cannot make an inference without observation. Observations lead to inferences. Inferences are conclusions or guesses made from the observations. You could infer that sugar makes a cookie taste sweeter after experimenting with no sugar and observing that it tasted bitter. You could infer that more weight allows things to travel further after going down a ramp after measuring the distances different weights travel, graphing it, and observing the data.

Answers
The correct answers are:
-Genetic variation decreases in a population of prey after natural selection acts on it.
-Genetic variation exists in a population leading to individuals with adaptations with different survival frequencies.
Genetic variation creates new variants of a gene; such a variant is called an allele. These variations occur as a result of the interaction between individuals with their environment, where it affects them in a way that determines their survival or not, as a consequence of their adaptability to the surrounding context. Thus, natural selection occurs, which establishes which individuals survive and which individuals do not. Thus, individuals characterized as prey who develop defense elements against hunters will be the ones who survive, while those who do not will be the ones who will perish.

WHAT IS CELLULAR RESPIRATION?
Cellular respiration is the process by which living organisms obtain energy from organic sources. Cellular respiration combines glucose and oxygen as reactants to form carbon dioxide (CO2), water (H2O), and energy.WHAT IS DEHYDRATION SYNTHESIS?
Dehydration synthesis is a reaction whereby two smaller molecules come together to form a larger molecule with the loss of water. An example of dehydration synthesis reaction is the formation of starch from the reaction of glucose molecules with the loss of water.Therefore, glucose is a reactant of both cellular respiration and dehydration synthesis.

Answers
Answer:
These are some of the disadvantages of sexual reproduction: time and energy are needed to find a mate.
hope this helps!
A disadvantage of sexual reproduction is the fact that ADDITIONAL ENERGY is required to complete a life cycle.
Sexual reproduction can be defined as a type of reproduction that involves a complex life cycle in which germinal haploid cells called gametes combine to produce a diploid (2n) cell called the zygote.Subsequently, this zygote then divides to produce an adult organism.In plants, the most important disadvantage of sexual reproduction is that energy is required to complete a complex life cycle (i.e., zygote development).The diploid (2n) multicellular stage in the life cycle of a plant is known as the sporophyte.In conclusion, a disadvantage of sexual reproduction in plants is that ADDITIONAL ENERGY is needed to complete a complex life cycle.
