If a DNA molecule has 40% Cytosine, what percent of it would be Adenine? Explain your reasoning.
Answer:
60%
Explanation:
Answer:
:)
Explanation:
The total amount inside of all nitrogenous bases equal to 100%, with cytosine equalling 40%, Adenine would equal 10%, and you also have to include Guanine which would be another 40% equalling 90% then you have Thymine which would be the other 10%
Based on figure 2-2, how many electrons does an atom of Aluminum contain? (assume all atoms are neutral)
Answer:
see exp.
Explanation:
Aluminum has 13 electrons in a neutral atom. The 1S2, 2S2 and 2P6 shells are full, and so is the 3S2. The 3P1 shell has one electron in it (in Al's neutral atom) and that gives aluminum one lone valence electron and two "semi-valence" electrons which can be loaned out. :D

Why might more and more people be using clean energy instead of fossil fuels ? Use evidence from the text to support your answer .
Answer:
I don't have the information from the text book but. People might more and more be using clean energy instead of fossil fuel is because fossil fuel is limited. It's a non-renewable, it takes millions of years to form. Also because global warming is making a big impact on our planet, using clean energy instead of fossil fuel can reduce slow green house emission.

Monomers can be thought of as
A. highly unstable compounds.
B. Lego pieces or building.
C. long chain compounds.
Answer: B
Explanation:
Monomers are atoms or small molecules that bond together to form more complex structures such as polymers (which are long chain compounds)
Monomers are long chain compounds. So, the correct option is (C).
What are Monomers?A monomer is defined as a molecule which can react with other monomer molecules to form a larger polymer chain. It is also a three-dimensional network formed by a process called polymerization.
These are the molecules of any of a class of compounds mainly organic compounds which can react with other molecules to form very large molecules known as polymers.
Examples of monomers are glucose, vinyl chloride, amino acids and ethylene where each monomer is linked to form different types of polymers like glucose, glycosidic bonds which link sugars to form polymers like glycogen, starch and cellulose binds monomers.
Thus, Monomers are long chain compounds. So, the correct option is (C).

Explanation:
autonomic reflexes enable the ans to control what kinds of visceral functions? check all that apply.
Given what we know about the Autonomic Nervous System we can confirm that autonomic reflexes enable the ANS to control functions such as heart rate, urination, and breathing rates.
These are among the many visceral functions that the Autonomic Nervous System controls. As per the pattern that is being established, we can conclude that the Autonomic Nervous System functions at a subconscious level, controlling the visceral functions that do not require conscious thought.
Despite this, some organs can also be controlled consciously, such as the lungs and bladder. Other visceral functions such as heart rate, digestion, and even ocular responses, are not able to be controlled consciously.

The researcher who theorized that hypnosis comes about as a form of roleplay between hypnotist and subject is Milton Erickson, who is in Option D. Milton Erickson was a famous American psychiatrist and psychotherapist.
What is Milton Erickson?He is widely known for his pioneering work in the field of hypnosis. He believed that hypnosis is a form of communication between the hypnotist and the subject and that it involves a process of "roleplay" in which both parties take on certain roles or identities. In this sense, the hypnotist takes on the role of a facilitator or guide, helping the subject access their own inner resources and abilities. The subject, on the other hand, takes on the role of an active participant in the hypnotic process, using their own imagination and creativity to bring about positive changes in their thoughts, feelings, and behaviors.
Hence, the researcher who theorized that hypnosis comes about as a form of roleplay between hypnotist and subject is Milton Erickson, who is in Option D.

Which two atoms form an ionic bond?
A.sodium and bromine
B. two sodium atoms
C. two oxygen atoms
D fluorine and chlorine
Answer:
sodium and bromine
Explanation:
The one valence electron from sodium would be transferred to the bromine atom so they can both have an octet.
Which two atoms form an ionic bond?
Answer : A
Explanation : Ionic bond is a type of chemical bond and binds the chemical molecules together. Ionic bond is formed by the transfer of electrons from an electropositive element ( metal) to the electronegative element (non metal).
Sodium is an electropositive element and contains one positive charge. Bromine is an electronegative element with a single negative charge over it. Sodium gives the electron to bromine and results in the formation of ionic bond.
Thus, the correct answer is option (C).

A growing community considers building a new hospital closer to residential neighborhoods. This will get residents to emergency care faster and save lives when it is
needed. The only land available near residential areas is a forested wetland that supports a variety of species. What is a social consequence of not using the land
for a new hospital?
Emergency care is farther away, risking the health and well-being of a growing community
Preserving the ecosystem may upset residents in a community with a hospital shortage.
O If the wetland is protected, residents have fewer environmental concerns about the area.
It protects the lives of species and prevents a reduction in carbon sequestering by the trees.
The social consequence of not using the land is that it will protect the lives of species and prevents a reduction in carbon sequestering by the trees.
A social consequence refers to any unforeseen event which can be positive or negative, experienced by a society and has an effect on them.
A positive social consequence benefits a group of the socially connected group and can also stimulate future purpose.
A negative social consequence has its repercussions and can be attributed to negligence and bad factors.
Conservation of the ecosystem is paramount as well as the survival of the community.
A positive social consequence from the given information is that if the forested wetland is preserved to support a variety of species, It will protect the lives of the species and prevent a reduction in carbon sequestering by the trees.
The community could have emergency ambulances to cater for the movement of patients in case of emergency to the hospitals or educate them on how to take good care of their health and how to minimize hazards at home and offices.

Describe prokaryotic cells. Include general characteristics and indicate the one feature that eukaryotic cells have that prokaryotic cells do not.
Please no links!
Answer:
prokaryotic cells — e.g. Bacteria
eukaryotic cells — e.g. Animal/Plant cells
Prokaryotic Cells are unicellular organisms that don’t have a nucleus, but have their DNA unbound (or uncompressed) within the cells cytoplasm, they also have circular structures (or rings) called plasmids which carry additional Genetic Information.
Specific Example: A bacterium is an example of a prokaryotic cell, and it has a cell wall, cell membrane, and even a capsule.
One feature that Eukaryotic cells have which Prokaryotic cells don’t is a Vacuole (this is just one feature).
Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and don’t have organelles. Many also have a capsule or slime layer made of polysaccharide (ignore this word if you havent learn about it yet).
