Small insects can walk across the surface of calm water.
Their feet push the surface of the water down slightly,
somewhat like a person walking across a trampoline, but
they do not break the surface. What is the best
explanation for why this happens?
A. The insects are light enough so that they do not break the hydrogen bonds holding the water molecules
B. The insects actually use their wings to hover slightly above the waters surface and they only skim it with their feet
C. The insects feet are non- polar so they are repelled by the polar water molecules and are pushed away from the waters surface
D. The insects are small enough to see the individual water molecules so they are able to step carefully from one molecule to the next
Answer:
A. Insects are light enough so that they do not break the h bonds holding the water molecules together
Explanation:
The insects are light enough so that they do not break the hydrogen bonds holding the water molecules when they walk across the surface of calm water their feet push the surface of the water down slightly and it is due to surface tension.Thus, option A is correct.
What is surface tension?Surface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible.
Surface tension is responsible for the shape of liquid droplets and the surface tension of water is about 72 mN/m at room temperature.
Water has a tremendous amount of surface tension due to which small mass distributed effectively on its surface.
Surface tension is represented by the symbol T.
Therefore,the insects are light enough so that they do not break the hydrogen bonds holding the water molecules when they walk across the surface of calm water their feet push the surface of the water down slightly and it is due to surface tension.Thus, option A is correct.

There is an enzyme in your stomach. Explain how the enzyme would be affected if it was moved
the small intestines.
Answer:
It might not work as efficiently because the conditions are different
Explanation:
The stomach is highly acidic compared to the small intestine. That means the pH is higher in the small intestine. Stomach enzymes are adapted to work at low pH, but might not work at a higher pH as in the small intestine. They might not be able to efficiently catalyze reactions in the small intestine.

C6H12O6
Which information can be determined from the chemical formula?
Answer:
The number of atoms of each element in a glucose molecule
The information that can be determined from the given formula is the number of atoms of each element in a glucose molecule. The correct option is D.
What is an element?Any substance that cannot be decomposed into simpler substances by ordinary chemical processes is referred to as a chemical element. Elements are the fundamental building blocks of all matter.
An element is a pure substance that cannot be broken down into simpler substances through physical or chemical means.
An element is composed of the same type of atoms. Metals, nonmetals, and metalloids are the three types of elements. The symbols for the elements are used to represent them.
Glucose is made up of three elements: carbon, hydrogen, and oxygen. 6 carbon atoms bonded together in a chain with oxygen and hydrogen atoms.
The formula for the glucose can be illustrated as [tex]C_6H_1_2O_6[/tex]

What are the parts of the compound light microscope
: The three basic, structural components of a compound microscope are the head, base and arm.
•Head/Body houses the optical parts in the upper part of the microscope.
•Base of the microscope supports the microscope and houses the illuminator.
•Arm connects to the base and supports the microscope head.
The head, base, and arm are the three fundamental structural elements of a compound microscope.
Thus, Head/Body houses the optical components in the microscope's upper section. The base of the microscope holds the illuminator and supports the microscope.
Arm supports the microscope head and is attached to the base. The development of the field of microbiology brought into focus the significance of the identification, seeing, observation, and comprehension of microbes, including their structural morphologies and mechanisms.
The study of tiny creatures and agents that can only be seen and investigated under a microscope falls under the purview of microbiology.
Thus, The head, base, and arm are the three fundamental structural elements of a compound microscope.

Orchids are flowering plants that dependent visa punishment a pol a population of orchids in a rain forest has reached its carrying capacity rainforest be population is a limiting factor in the orca population what will happen to the orchids caring capacity of the rainforest
Answer:
Explanation:
The question is incomplete below is the correct version of the question.
Orchids are flowering plants that depend on bees for pollination. A population of orchids in a rainforest has reached its carrying capacity. The size of the rainforest's bee population is a limiting factor of the orchid population. What will happen to the orchids' carrying capacity if the rainforest's bee population decreases? A. The carrying capacity will not change because it is a constant property of a species. B. The carrying capacity will not change because it is a constant property of an ecosystem. C. The carrying capacity will decrease because the level of the limiting factor decreases. D. The carrying capacity will increase because the level of the limiting factor decreases.
Answer :C. The carrying capacity will decrease because the level of the limiting factor decreases.
Explanation:
The carrying capacity of a system is how much population an habitat can sustain depending on the available resources without leading to competition. This resources include food, water, space.
Since Rain forest bee is a limiting factor for orchid therefore Orchid population is dependent on the Rainforest bee's population so a decrease in the bee's population will lead to a decrease in the orchid population.
This will then lead us to a decrease in the carrying capacity of the system due reduction in the population of the limiting factor the bee because carrying capacity is population dependent.
Which of the following is true:
- Since the active site has a specific shape it can only fit one substrate.
- The active site can fit any type of substrate.
- Nothing can fit or bond with the active site of an enzyme.
Answer: Since the active site has a specific shape it can only fit one substrate.
Explanation: I took one for the team on Ed puzzle.
Since the active site has a specific shape it can only fit one substrate. The correct option is A.
What is active site of enzyme?The active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction in biology and biochemistry.
The active site is made up of amino acid residues that form temporary bonds with the substrate (binding site) and residues that catalyze the substrate's reaction (catalytic site).
The active site of an enzyme is the specific region of the enzyme where a substrate binds and catalysis or chemical reaction occurs.
It is a protein structural element that determines whether the protein is functional when subjected to an enzyme reaction.
A holoenzyme is a fully active enzyme that is made up of a protein portion (apoenzyme) and a cofactor.
Thus, the correct option is A.
