Could you have identified any of the minerals after having described only a few, rather than all, of the properties you tested? If so, give an example.
Answer:
Unfortunately, you can rarely identify a mineral only by its color. Sometimes, different minerals are the same color. For example, you might find a mineral that is a gold color, and so think it is gold. But it might actually be pyrite, or “fool's gold,” which is made of iron and sulfide.

Lyme disease is spread by ticks that attach to an animal to feed. Which describes the role of the tick?
Lyme disease is spread by ticks that attach to an animal to feed, and ticks play a critical role in the transmission of Lyme disease, as ticks are external parasites that feed on the blood of animals, including humans, and can transmit infectious diseases as they feed; this is option C.
What is a tick?When an infected tick attaches itself to an animal, it can transmit the bacterium responsible for Lyme disease, which is called Borrelia burgdorferi. The bacterium is typically present in the tick's saliva, and it can be transmitted to the animal as the tick feeds on its blood. Once the bacterium enters the animal's bloodstream, it can spread throughout the body and cause a range of symptoms, including fever, headache, fatigue, and a characteristic bullseye rash. Ticks play a critical role in the transmission of Lyme disease because they serve as both a vector and a reservoir for the bacterium.
Hence, ticks play a critical role in the transmission of Lyme disease, as ticks are external parasites that feed on the blood of animals, including humans, and can transmit infectious diseases as they feed; this is option C.

Part A: Explain how Enzyme A acts as a catalyst in the reaction Be sure to include energy and time in your response.
Part B: Conditions around an enzyme change and affect the shape of the enzyme’s active site. Predict how this would affect the enzyme’s ability to catalyze (speed-up) the reaction.
Answer:
A) Enzymes and chemical catalysts both affect the rate but not the equilibrium constant of a chemical reaction. Reactions proceed downhill energetically, in accord with the Second Law of Thermodynamics. Catalysts merely reduce the time that a thermodynamically favored reaction requires to reach equilibrium. Remember that the Second Law of Thermodynamics tells whether a reaction can occur but not how fast it occurs.

To test the hypothesis that mussels are osmoconformers, researchers exposed mussels to water of varying osmolarities and then drew hemolymph samples from the mussels. The results are presented below. Is the researchers' hypothesis supported by the data? Explain.
The question is incomplete, I included an attachment that completes the question as well as show the options to be chosen from.
Answer: YES, SUPPORTED
Explanation: When we talk of Osmoconformers, we are talking of the organisms that live in the marine habitat.
These Osmoconformers have the tendency of maintaining their internal fluid isotonic that is isotonic to their external environment in church they live. They have an osmotic pressure that is equal to the osmotic pressure of their surrounding environment.
In the table provided in the attachment section,it clearly stated as we can see the increase in osmolarity of water,the haemolymph osmolarity increase in order to maintain isotonic realtion so that,there will be no much exosmosis (osmosis).

Which is the best definition of activation energy?
the energy required to end a chemical reaction
the energy required to bind a substrate to an active site
the energy required to form or break the bonds of reactant molecules
the energy required to re-form bonds in product molecules
Answer:
the energy required to form or break the bonds of reactant molecules
Explanation:
Activation energy is defined as the force needed to bind a substrate to an active site. So, the correct option is B.
What is Activation energy?The bare minimum of energy required for compounds to undergo a chemical reaction is known as the activation energy. In terms of joules per mole, kilojoules per mole, or kilocalories per mole, a reaction's activation energy is quantified. Activation energy is defined as the force needed to bind a substrate to an active site.
The difference in energy content among atoms or molecules inside an activated or transition-state configuration compared to atoms and molecules in their original configuration is known as the activation energy in transition-state theory.
Therefore, the correct option is B.

How could a mutation or change in a DNA sequence impact the overall function of a cell?
Answer:
DNA is a dynamic and adaptable molecule. As such, the nucleotide sequences found within it are subject to change as the result of a phenomenon called mutation. Depending on how a particular mutation modifies an organism's genetic makeup, it can prove harmless, helpful, or even hurtful.

Erik remembered that his
science teacher had told him that an explosion in space could not really be heard. Why
is this so?
Answer:
Because space is a vacuum, gases released into space expand very quickly, and as they expand their density decreases. So say you were in a spaceship in the middle of a big space battle and a nearby ship exploded. The exploding ship would release gases and technically sound could travel along with them

How has tidal locking affected our moon?
a. The rotational period matches the orbital period
b. it rotates perfectly allowing us to see all sides
c. the moon is locked in its orbit and cannot get any closer or further from us
d. the moon never rises or sets in the sky
Answer: A. The rotational period matches the orbital period.
Explanation: Tidal locking results in the moon rotating about its axis in the same time it takes to orbit Earth. So the moon is tidally locked in to the Earth ,because it takes the exact same amount of time as it takes to orbit the Earth Which is why we only see one side of the moon.
