Answer:
B. Can be used to derive Kepler's third law of planetary motion.
Explanation:
According to gravitational law, force of attraction exists between two bodies, with the force depending on the mass of the two bodies and distance between them. It can be used to derive Kepler's third law, according to which

what would most likely happen if an error occurred when RNA was receiving coding information?
Answer:
This RNA would form proteins with incorrect coding and would result in a genetic mutation.
Explanation:
Mutations can be defined as changes that occur in the genetic material of living organisms. These changes are an important source of genetic variability and are often responsible for the emergence of new species. Changes in genetic material are extremely important, it is the nucleic acids that carry the information needed for protein synthesis, when one of these nucleic acids (RNA or DNA) is incorrectly coded, the result will be an incorrect protein that will form a characteristic that wasn't being expected in the body .

Melatonin appears to adjust the sleep phase of the sleep/wake cycle of some people. melatonin appears to adjust the sleep phase of the sleep/wake cycle of some people.
a. True
b. False
The answer is true. Melatonin is a hormone that is created by the pineal gland in animals and controls sleep and alertness. It seems to have 2 possible interacting effects on the sleep-wake cycle. First, it encourages sleep and stability in a “hypnotic” function by escalating the homeostatic coerce to sleep. Second, it entrains and modifies the process c in a “chronobiotic” function.

They either match up with a receptor molecule on the surface of the cell or enter the cell through the membrane) (B. The carbohydrate tag is interpreted in the ribosomes, and the signal is passed on to the nucleus of the cell) (C. They connect with another cell partm such as the Golgi apparatus, where hormones interpret the signal) (D. They connect with an adjacent cell where an ion linked receptor carries them into the nucleus)
Cryptozoology is a field of study aimed at proving the existence of mystery animals such as bigfoot and the Loch Ness monster why is cryptozoology not consider a true science
Answer:
Cryptozoologists aim to prove the existence of organisms from folk lore like big foot, chupacabra, Loch Ness monster etc. These organisms are referred to as cryptids. This branch of science falls under the category of pseudoscience because the usual scientific methods are not used here. It neither falls under the category of zoology nor under the category of folkloristics. Rather on depending on facts and true evidence, it usually depends on word of mouth anecdotal information. Hence, it is also criticized sometimes for not being a true science field.
Describe the effects that enzymes can have on substrates
Answer:
The effect of enzyme on substrate depends o the concentration of substrate and it affects the rate of reaction.
Explanation:
If the concentration of the substrate is low in a mixture, then substrates will bind to enzyme which will slow the rate of reaction. But if the concentration of the substrate is increased, then there will be more substrate for enzymes to work on and the rate of reaction will be increased.
There is a point upto which the enzymes will be involved in catalyzing action. When that threshold point is reached the increase in concentration of substrate will no longer increase the rate of reaction instead the rate if reaction will be uniform.

how are hydrogen bonds different from covalent bonds?
A.) They are organic.
B.) Hydrogen bongs are weaker bonds that form from molecules that have a slight positive charge on one side and a slight negative charge on the other.
C.) They have valence electrons.
D.) The resulting compounds contain carbon.
Hydrogen bongs are weaker bonds that form from molecules that have a slight positive charge on one side and a slight negative charge on the other.
Molecules with a tiny positive charge on one side and a slight negative charge on the other create weaker bonds called hydrogen bongs. Thus, option B is correct.
What is a hydrogen bond?Chemical bonds that are present in covalent compounds include covalent and hydrogen bonds.
The sharing of electrons between atoms results in the formation of a covalent bond. The attraction between two atoms of two distinct molecules results in the formation of a hydrogen bond.
When a hydrogen is covalently bound to one electronegative atom, an attraction called a hydrogen bond is created.
Because a hydrogen is an attraction rather than a true bond, it differs from a covalent bond. Because the positive charge of the hydrogen is drawn to the negative charge of another atom, there is an attraction.
Therefore, hydrogen bonds different from covalent bonds.

Active reading (color-coding, highlighting, outlining, note-taking) is an effective strategy for which type(s) of learners? (select all that apply.)
Active reading techniques like color-coding and highlighting are mainly beneficial for visual and kinesthetic learners as well as for analytic learners who favor organization. Auditory and global learners may find less use for these strategies, but since most people are a blend of learning types, a variety of these techniques can cater to different preferences and needs.
Active reading strategies such as color-coding, highlighting, outlining, and note-taking are effective for various types of learners. Visual learners benefit from seeing information in different colors and formats, which helps with organization and recall.
These strategies can also aid kinesthetic/tactile learners who prefer interacting with the material through hands-on activities like writing and pointing out. While these methods are primarily used by visual and kinesthetic learners, they can also support analytic learners who like to break down information into structured formats.
On the other hand, auditory learners may not find these tactics as helpful because they prefer to learn through listening. Lastly, global learners who look at the big picture may find outlining and note-taking useful for making connections between concepts, but might not rely as heavily on color-coding and highlighting.
It's essential to recognize that most individuals do not fit into a single type of learning style; therefore, using a blend of different active reading techniques can be beneficial in appealing to mixed learning preferences. Moreover, while certain learning styles might have a 'grain of truth', it's crucial to remember that individuals can learn in all three modes depending on the context, and having a dominant style should not confine their learning strategies.

Imagine you have paid for a genetic test from a company that can report your probability of developing alzheimer's disease based on the presence of a certain allele. this test would be examining your ____ profile.
Final answer:
Imagine you have paid for a genetic test from a company that can report your probability of developing alzheimer's disease based on the presence of a certain allele. this test would be examining your genetic profile.
Explanation:
The genetic test that you have paid for would be examining your genetic profile. Specifically, it would be looking for the presence of a certain allele that is associated with Alzheimer's disease. Alleles are different forms of a gene, and they can have different effects on an individual's likelihood of developing a certain condition or disease.
In the case of Alzheimer's disease, there are several genes that have been identified to possibly increase the risk. One well-known gene is apolipoprotein E (APOE), which has a variant (E4) that increases the probability of developing the disease. Other genes have also been implicated in the pathology of Alzheimer's.
By analyzing your genetic profile and looking for the presence of specific alleles, the genetic test can provide information about your probability of developing Alzheimer's disease later in life.

Which of the following is located in the tropical climate zone?
a. desert
b. chaparral
c. taiga
d. tundra
Answer: a. Desert
Explanation:
The tropical climatic zone has three different biomes such as tropical rainforests, the tropical savannas and tropical deserts. The tropical climatic zone is the hottest of all the climatic zones as it can be found on and near the equator, this region receives the maximum sunlight energy year around.
Therefore, on the basis of the above information, the desert is the correct option. The desert biome is the hottest and driest region of the earth. This region receives very low annual rainfall.
