the long legs of wading birds
the croak of frogs
the quills of a porcupine
the venom of snakes
The physical adaptation among the option that increases an organisms
chances of finding a suitable habitat is the long legs of wading birds
An adaptation is a characteristic that helps an animal survive in its habitat.
Any animal who successfully survives on land or water must have behavioural
and physical trait or attributes or adaptation that assist it to achieve those
goals.
This physical adaptation might be body growth, body covering during
weather change, body functioning or even body parts.
The physical adaptation among the option that increases an organisms
chances of finding a suitable habitat is the long legs of wading birds.
The long legs of wading birds assist them to find a suitable habitat. The long
legs can move through shallow water without wetting their feathers.
There long leg give them better eye sight to search for food and suitable
habitats.

Which does ionic bonding involve?
In the malate-aspartate shuttle, _____ is reduced to _____ in the cytosol. oxaloacetate; malate aspartate; malate malate; aspartate malate; oxaloacetate aspartate; oxaloacetate
The malate-aspartate shuttle enables oxidative phosphorylation by allowing electrons to be moved across the inner membrane in the mitochondrion during glycolysis in eukaryotes.
In this malate-aspartate shuttle, oxaloacetate is reduced to malate in the cytosol.
During this biochemical system process, the cytosolic malate dehydrogenase which is the primary enzyme present in this shuttle system catalyzes the reaction of oxaloacetate and NADH to produce malate and NAD in the cytosol. This system enables oxidative phosphorylation in eukaryotes.Learn more: https://brainly.com/question/17216910

what are valence electrons? why are they so important in chemistry?
Answer:
Valence electrons are negatively charged particles located in the outermost shell of atoms that can be transferred or shared with other atoms. Valence electrons are important in chemistry because the number of valence electrons in a particular atom can be used to determine how the atom will react chemically with other atoms.
A wave is moving towards shore with a velocity of 5.0 MS if it’s frequency is 2.5 Herz what is the wave length
Answer:
2 mExplanation:
The wavelength of a wave can be found by using the formula
[tex]\lambda = \frac{c}{f} \\[/tex]
where
c is the speed of the wave
f is the frequency
From the question
c = 5 m/s
f = 2.5 Hz
We have
[tex] \lambda = \frac{5}{2.5} = 2 \\ [/tex]
We have the final answer as
2 mHope this helps you

Write a Claim based in this question: What happens in the atmosphere and how
is it related to the water cycle.
Answer:
The atmosphere is the superhighway in the sky that moves water everywhere over the Earth. Water at the Earth's surface evaporates into water vapor which rises up into the sky to become part of a cloud which will float off with the winds, eventually releasing water back to Earth as precipitation.

which of the following elements forms coloured compounds. A. Normal B. Transition C. Lanthanicles D. Inner transition
Answer:
B. Transition
Explanation:
Transition elements form coloured compounds because they have unfilled d orbitals.
A clear liquid in an open container is allowed to evaporate. After three days, a solid is left in the container. Was the clear
liquid an element, a compound, or a mixture?
The liquid did not chemically bond after 3 days, therefor it is a mixture.

(6) Predict the number of valence electrons for each of the following elements (4 pts)
(a) P
(b) Ar
(c) c
(d) Ni
Answer:
P = 5, Ar = 8, C = 4, Ni = 2
Explanation:
All these answers can be based off which column of the periodic table each element is in. This does exclude the transition medals in between the 2nd and 13th columns. Column 1 = 1, Column 2 = 2, Column 3 = 3 and so on. Transition metals can be determined based on their electron configuration, which in this case, Ni has 2 electrons in its outer most shell.

What type of bond would be formed between hypothetical elements X and Y in the the compound XY based on their electronegativity difference?
A. Nonpolar covalent because the difference in electronegativity is greater than 0.4, but less than 1.7
B. Nonpolar covalent because the difference in electronegativity is greater than 1.7
C. Polar covalent because the difference in electronegativity is greater than 0.4, but
less than 1.7
D. lonic because the difference in electronegativity is greater than 0.4, but less than
1.7
The bond is polar covalent because the difference in electronegativity is greater than 0.4, but less than 1.7.
Electronegativity refers to the ability of an atom in a compound to attract the electrons of the bond towards itself. It is a periodic trend that increases across the period but decreases down the group.
The electronegativity difference between the two atoms as shown in the question is 1.55. This means that the bond is polar covalent because the difference in electronegativity is greater than 0.4, but less than 1.7.

in a battery that uses a licoo2 cathode approximately 50% of the lithium migrates from the cathode to the anode on charging. in a battery that uses a limn2o4 cathode what fraction of the lithium in limn2o4 would need to migrate out of the cathode to deliver the same amount of lithium to the graphite anode?
Answer:
92.4%
Explanation:
Assume 100g of the cathode material. The LiCoO2 cathode has 7.09 g of Li. If half of Li migrates during charging, 3.55g Li migrates. 100g of the LiMn2O4 cathode contain 3.84g of Li. The fraction of lithium in LiMn2O4 that would need to migrate out of the cathode to deliver the same amount of lithium to the graphite anode:
(3.55g/ 3.84g ) * 100% = 92.4%
From electrolysis, 92.4% would need to migrate out of the cathode to deliver the same amount of lithium to the graphite anode.
What is electrolysis?
Electrolysis is a technique that uses direct electric current (DC) to drive an otherwise non-spontaneous chemical reaction. Electrolysis is commercially important as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell. The voltage that is needed for electrolysis to occur is called the decomposition potential.
