Explain why the shape of a leaf make a good tool for photosynthesis
Answer:Leaves are ideal for photosynthesis because they are usually broad and flat, giving plenty of surface area for light to be absorbed. They are also thin, which means diffusion of gases such as carbon dioxide can happen quickly. Leaves cannot perform photosynthesis without chlorophyll.

What type of density is the hurricane?
Answer:
what one?
Explanation:
Answer:
A tropical cyclone with maximum sustained winds of 74 mph (64 knots) or higher. In the western North Pacific, hurricanes are called typhoons; similar storms in the Indian Ocean and South Pacific Ocean are called cyclones.
Explanation:
Hurricanes form over the ocean, often beginning as a tropical wave—a low pressure area that moves through the moisture-rich tropics, possibly enhancing shower and thunderstorm activity.
Which of the following best describes a way in which cellular response might be affected if scaffolding proteins were not present in a cell's signal transduction pathway?

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.
Explanation:
Identify the most likely cause of the following scenario:
A street in a desert is filled with cracks despite rarely being driven on by cars.
The asphalt is cracked from constant expanding due to heat during the day and contracting due to cold at night.
The asphalt is cracked due to animals burrowing to create homes.
The asphalt is cracked due to roots growing underneath from the lush rain forest surrounding the road.
The asphalt is cracked due to rusting caused by exposure to water and oxygen over long periods of time.

tube 1 contains water only. tube 2 contains a live snail. tube 3 contains a live green water plant. tube 4 contains both a live green water plant and a live snail. what compound that directly provides energy in living cells is being produced in every tube where cellular respiration is occurring?
Answer:
Explanation: Tube 1 doesn't contain an organism so it can't be that one. Both a snail and a plant are considered an organism, and cellular respiration occurs in almost any organism's cells

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

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.

WHO and WHEN proposed the Model of the Atom we believe in today?
Answer:
Atoms are so small that it is difficult to believe that all matter is made from atoms—but it is. The concept that atoms play a fundamental role in chemistry is formalized by the modern atomic theory, first stated by John Dalton, an English scientist, in 1808.

What is the difference between a subscript and a coefficient?
Science
Answer:
Explanation:
Subscripts are numbers that come after a symbol and below. Subscripts tell you the number of atoms of that element. If an element does not have a subscript, then it is understood that the subscript is 1.
. Compare: Compare the human and animal samples (human and mouse skin; human and worm neurons; human and fly muscle; human and frog blood). A. In general, are there any major differences that you can see? Explain.
Answer:
The epidermis which is the outermost layer of the skin vary when comparison is made between a human and animal skin.
Human skin has a thicker epidermis while Animals have a thinner epidermis.
The difference between human and insect muscles is that insect have mainly striated muscles which are primarily made of sarcomeres while animals have both the smooth and striated muscles.
The blood is different in humans and frog as humans red blood cells don’t have a nucleus while that of frogs have a nucleus in the red blood cells.
Human beings have very specific differences from other animals, due to their physical and biological constitution.
Based on this, we can answer the above question as follows:
Human skin and mouse skin are different in that human skin has seven layers, while mouse skin has between 10 to 20 layers.A worm has 302 neurons, while a human being has about 86 billion neurons.The fly has muscles adapted to flight, which allows these muscles to be rigid, resistant, and striated. On the other hand, human muscles are less rigid, are not adapted to flight, and can be smooth or striated.Human blood goes through a double circulation type and is of the complete type, while the frog's circulation is of the incomplete type, as it allows the mixture rich in oxygen with the blood rich in carbon dioxide.More information:

Explanation:
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).

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.
