Answer:
D. Draw conclusions
Explanation:
The scientific method
At the core of biology and other sciences lies a problem-solving approach called the scientific method. The scientific method has five basic steps, plus one feedback step:
Make an observation.
Ask a question.
Form a hypothesis, or testable explanation.
Make a prediction based on the hypothesis.
Test the prediction.
Iterate: use the results to make new hypotheses or predictions.
The scientific method is used in all sciences—including chemistry, physics, geology, and psychology. The scientists in these fields ask different questions and perform different tests. However, they use the same core approach to find answers that are logical and supported by evidence.

The 1st Law of Thermodynamics states that energy is neither created nor destroyed only transfer to forms. Why is a food chain an excellent example of this Thermodynamic law?
Answer:
Food chain is an excellent example of the first law of thermodynamics.
Explanation:
First law of thermodynamics states that energy of the universe is constant. It is always found in the universe in some form or the other. It cannot be destroyed or totally used up and we cannot also create energy out of anything in this world. Energy transforms from one form to another form.
Food chain is considered to be an excellent example of 1st law of thermodynamics. Every living organisms in the world posses energy. And all living organisms consumed each other or eat each other for their survival and consumes these energy to survive. So the energy possessed in one organisms or animal is transferred to the other organism that is higher in the food chain when they eats the lower organisms or animal in the food chain.
Thus energy transfers form one form to another.

The number of valence electrons an element has changes often, so we cannot use the periodic table to predict the number of valence electrons an element
has
True
False
Answer:
False
Explanation:
The number of valence electrons on an element is also the same or else it would be a different element.
The statement that the periodic table cannot be used to predict the number of valence electrons is: FALSE
The number of valence electrons an element has will always remain the same for the element to remain the same element, elese the element will changes with a change in valence electrons. therefore we can use the periodic table to predict the number of valence electrons that an element has.
A valence electron is an electron that is located in the outermost shell of an atom or element. It is negative and it is used for the formation of bonds between atoms or elements.
Hence we can conclude that The statement that the periodic table cannot be used to predict the number of valence electrons is: FALSE .

Since binary fission is the direct division of bacteria from which two cells result that means every hour the number of bacteria will double.
Answer:
the number of bacteria will double and 32
Explanation:
because in 1 hour its 2 and in 2 hours its 4 so it doubled or you can check in 3 hours it was 8 and in 4 hours it was 16 so it doubled. And when you double 16 do find the amount in 5 hours it is 32.

Stems, roots, leaves, and bark. The three fundamental organs of vascular plants are the roots, stems, and leaves; nevertheless, these organs frequently have undergone specialization for a variety of purposes and do not appear to be "typical."
What are organs of plants?An organ is a collection of tissues that perform the same function and are located in the same place. Roots are plant organs. They firmly anchor plants and have root hair cells on their surface that absorb water and nutrients from the soil. Additional plant organs include flowers, leaves, and stems. Among these, the stems that support reproductive organs, such as angiosperm flowers and conifer cones, are the most visible. A group of tissues that collaborate to perform a specific function as a structurally sound functional unit. Plants' major organs are the leaf, root, stem, and reproductive organs. The leaf's primary function is to produce food for the plant via photosynthesis.To learn more about organs of plants refer to:

what is symbiosis?
Explanation:
A close, prolonged association between two or more organisms of different species, regardless of benefit to the members is symbiosis.
Hope it helps :)
Answer:
Symbiosis
Explanation:
Symbiosis is any type of a close and long-term biological interaction between two different biological organisms, be it mutualistic, commensalistic, or parasitic. The organisms, each termed a symbiont, must be of different species. In 1879, Heinrich Anton de Bary defined it as "the living together of unlike organisms". The term was subject to a century-long debate about whether it should specifically denote mutualism, as in lichens. Biologists have now abandoned that restriction.

Explanation:
A genetic mutation causes a squirrel to be born with much darker fur than its parents.
How will this mutation most likely affect the squirrel population?
Because the trait was caused by a mutation, it will not be passed on to any offspring, resulting in the disappearance of the trait.
Because the trait was caused by a mutation, it will be passed on to offspring over many generations, resulting in a population of darker squirrels.
If the trait is unfavorable, it will be passed on to offspring over many generations, resulting in a population of darker squirrels.
If the trait is favorable, it will be passed on to offspring over many generations, resulting in a population of darker squirrels.
Answer: If the trait is favorable, it will be passed on to offspring over many generations, resulting in a population of darker squirrels.
The mutation most likely affects the squirrel population if the trait is favorable, it will be passed on to offspring over many generations, resulting in a population of darker squirrels. The correct option is D.
What is mutation?A mutation is a change or modification in the DNA or gene sequence of the organism. The modification is done due to mutagens. These mutagens delete or insert or replace the bases and cause differences.
Here, due to mutation, the color of the squirrel changed to black, so if the gene of black color will be transferred to future generations, it can be dominant or recessive.
Thus, the correct option is D, If the trait is favorable, it will be passed on to offspring over many generations, resulting in a population of darker squirrels.

It is said that “sexual reproduction promotes diversity of characters in the offspring.” Justify.
Answer:
Since sexual reproduction needs two individual animals for it to occur and genes from both, the offspring won’t be exactly like one or the other parent, so, on a larger scale, we will all be unique and diverse.
For further understanding, let’s think of an example. Your dad and mom are different than you are because you are created from both of their genes combined, creating a unique you. This promotes diversity for that we are all unique.
