what are the similarities and differences between the crocodile , sheep , and gorilla digestive system?
Answer: Crocodile is a reptile whereas sheep and gorilla are the mammals.
Explanation:
Crocodile, sheep, and gorilla have alimentary canal in their digestive system. The urea is the common excretory waste.
Mouth is typically large in case of crocodile and comparatively small in sheep and gorilla.
In crocodile more sharp teeth are present as compared to sheep and gorilla for mastication of food and capturing the prey like fish or large animals like zebra.
The crocodile palate is more stronger than sheep and gorilla because it enable it to chew the bones of the prey.
Suzanne has a cat and uses a pet carrier to take her cat to the veterinarian. After a few years, the cat runs away and hides every time Suzanne gets the carrier out. Which best describes the cat's behavior? instinct reflex conditioned imprinting
Answer:
conditioned
Explanation:
The best term to describe the behavior of the cat is conditioned.
The cat has been conditioned to respond in a specific way to the pet carrier over time due to certain experiences - most likely, unpleasant ones. With repeated unpleasant experience associated with the per carrier, the cat has been conditioned to dislike/fear the pet carrier and thus, the recorded behavior.
Answer:
conditioned

What is the relishing hip between the chemical energy provided by the battery and the electrical energy produced according to the law of conservation of energy
Answer:
Equal
Explanation:
Energy is always conserved in the nature and it is an universal law. According to the law conservation of energy, it is said that energy can never be created out of something and we can never destroy and vanish any energy in any form. Energy in any form can only be transformed to some other forms of energy. This is known as conversion of energy.
In the context, the chemical energy that is produced by the battery and the electrical energy produced should be equal.
How does the suns energy contribute to the movement of water in the water cycle?
Answer:Evaporation
Explanation:
The suns heat speeds the movement of water molecules, until the molecules move fast enough that they jolt out the surface of the water individually. Overtime the water gradually evaporates into water vapor.
what would happen if the
attractive forces between all of the particles
of matter on Earth were equal?
The magnitude of attractive forces between particles that compose matter determine the state of matter. Hence, if all particles of matter on earth have equal attractive forces, only a single state of matter (solid, liquid or gas) will exist on earth.
Matter exists in three states;
SolidLiquidGasIn solids, there exists the greatest magnitude of attractive forces between particles.
There are weaker inter-molecular attractive forces between liquid particles. However, inter molecular attractive forces are almost non-existent in gases.
The reason for the existence of different states of matter on earth is difference in magnitude of inter molecular attractive forces in each state of matter.
If all particles of matter possess equal attractive forces, only one state of matter will be found on earth; either solid, liquid or gas.

A beach ball has a mass of 5g a volume of 20cm3. What is the object's density?
Answer:0,25 g/cm3 creo
Explanation:densidad es masa entre volumen
Answer:
0.25 g/cm³
Step-by-step explanation:
As we know
The density is given by
Density = Mass / Volume
Putting the values
Density = 5g / 20 cm³
Density = 0.25 g/cm³

A photon has an energy of 2.34x10-28 J. What is its frequency?
Answer:
f = 3.53×10⁵ s⁻¹
Explanation:
Given data:
Energy of photon = 2.34×10⁻²⁸ J
Frequency = ?
Solution:
h = 6.63 ×10⁻³⁴
Formula:
E = hf
2.34×10⁻²⁸ J = 6.63 ×10⁻³⁴ × f
f = 2.34×10⁻²⁸ J / 6.63 ×10⁻³⁴ Js
f = 0.353×10⁶ s⁻¹
f = 3.53×10⁵ s⁻¹

how to determine whether a liquid is pure water or not besides boiling the liquid?
Answer:
Explanation:
Aside the boiling point of water, another colligative property that can be used to identify pure water (or not) is the freezing point. Water freezes at 0 °C, but with the presence of impurities, there is a freezing point depression of the water. Thus, if the water is not pure, the liquid could freeze at a temperature lower than 0 °C (with a negative sign like -8 °C).

What kind of molecule can experience hydrogen bonding?
A. A nonpolar molecule containing a hydrogen atom
B. A molecule with hydrogen bonded to any nonmetal
C. A molecule with hydrogen bonded to O, N, or F
D. Any polar molecule containing a hydrogen atom
Answer:
Answer is C
Explanation:
C - A molecule with hydrogen bonded to O, N, or F
A molecule with hydrogen bonded to O, N, or F can experience hydrogen bonding. Therefore, the correct option is option C.
A hydrogen atom is attracted to another electronegative atom in a neighbouring molecule when it is connected to a strongly electronegative atom (O, N, or F). This attraction is more powerful than the usual dipole-dipole interactions between polar molecules.
The enormous electronegativity differential between hydrogen and the highly electronegative atom causes hydrogen bonding. The electronegative atom attracts the shared electrons in the covalent link, causing the hydrogen atom to gain a partial positive charge.

Tigers and crocodiles are more closely related than tigers and sharks. Which statement about shared characteristics best supports this statement?
Answer: Crocodiles and tigers both have four legs
Explanation: Even when sharks and tigers are both meat eaters, the question is about similarities between tigers and crocodiles, so D is out. A is about crocodiles and sharks, so it's out also. B suits for sharks too, so it's out too. C is the most suitable answer, because both animals have four legs, which means that they belong to the group of quadrupede animals.
Answer:
Crocodiles and tigers both have four legs
Explanation:
In what way do the atoms in the same row of the Periodic Table increase from left to right?
Answer:
As you move from left to right, the nucleus gains protons. This increases the positive charge of the nucleus and its attractive force on the electrons. At the same time, electrons are added to the atoms as you move from left to right across a period.
Explanation:
A gas is produced when 25 g of substance X is mixed into 60 g of solution Z in a beaker. The mass of the solution in the beaker after the reaction is 75 g. What is the mass of the gas released?
(X + Z -> gas + solution)
mass of the gas = 10 g
Further explanationThe law of conservation of mass :
In a closed / isolated system, the total mass of the substance before the reaction will be equal to the total mass of the reaction product.
Reaction
[tex]\tt X+Z\rightarrow gas+solution[/tex]
mass before reaction=mass after reaction
[tex]\tt 25+60=gas+75\\\\gas=25+60-75=10~g[/tex]
8. The following system contains 20.0 psi each of gases A and B in the end bulbs with an evacuated bulb in the centre. Both stopcocks are opened at once. What is the new overall pressure in the system?
I literally have no idea how to even start this, I know that the answer is 13.3 psi, but I don't have any clue why or how to get there.
Answer:
13.3
Explanation:
Before opening the stopcocks you have 40psi in total.
After that, those 40psi will be divided into 3bulbs, so 40/3=13.3psi for the system.
