Answer:
I am pretty sure it is False
Explanation:
Answer:
The second statement is false
Explanation:
Diffusion will typically occur until concentration gradients are the same both outside and inside of the cell. In order for the concentration to increase further inside of the cell requires a different transportation method, such as the use of a channel protein.

Temperature is an important factor that determines if matter is a solid or a liquid
True or false?
Answer:
true
as temperatures rise, the atoms become more active; as per the opposite (meaning as temperatures drop, the atoms start to settle down) liquid is the more medium state (because the temperature rises enough for the solid to become a a liquid but not too much that the liquid evaporates and turns into a gas) have a great day/night
What does the diagram show?
- one battery, two light bulbs, and three resistors
- one battery, two switches, and three light bulbs
- one switch, one resistor, and three light bulbs
- one switch, one light bulb, and three batteries
The diagram show one battery, two switches, and three light bulbs. Therefore, the correct option is option B.
What is electric circuit?Electric circuit: a way for current to travel. A battery or generator, a device that provides energy to a charged particles that make up the current, a device that uses current, such as a lamp, an electric motor, or a computer, as well as the connecting wires and transmission lines make up an electric circuit.
Ohm's law and Kirchhoff's rules are two fundamental laws that quantitatively define how electric circuits function. Many categories are used to categorise electric circuits. One-way current only flows through a direct-current circuit. As in most residential circuits, an alternating-current circuit transports current that pulses back and forth repeatedly every second. The diagram show one battery, two switches, and three light bulbs.
Therefore, the correct option is option B.

Hammerhead Shark Process of Sexual Reproduction
Answer:
The hammerhead sharks exhibit a viviparous mode of reproduction with females giving birth to live young. Like other sharks, fertilization is internal, with the male transferring sperm to the female through one of two intromittent organs called claspers. The developing embryos are at first sustained by a yolk sac.

True or false Cellular Respiration produces Glucose, Water, and ATP?
1. define what an ion is (make sure electrons are part of the definition)
2. explain (in terms of electrons) how the sodium is becoming a positive ion
3. explain (in terms of electrons) how the chlorine is becoming an a negative ion
4. Explain why the difference in charges causes them to become attracted and bond to make NaCl, also known as table salt.
Answer:
valence shell, has eight electrons in it, so the atom becomes positively charged. ... in energies and is useful in explaining why atoms form the ions that they do. ... which we write as Na 2O. The need for the number of electrons lost
Explanation:
1. An ion of an atom is one in which the number of protons and electrons is not the same. If there are more protons than electrons, an atomic ion has a positive charge and is called a cation. If there are more electrons than protons, the ion has a negative charge and is called an anion.
2. Such bonds are created when the outermost electrons of one atom (such as sodium) are transferred permanently to another atom (such as chlorine). The atom that has lost an electron becomes a positively charged ion (called a cation), while the atom that picks up the extra electron becomes a negatively charged ion (called an anion).
3. For a chlorine atom to become a chloride ion, it must gain an electron. The chloride ion has a negative charge and is written as Cl-. Chlorine gains an electron because it has seven valence electrons, and to be a full octet, it gains an electron. A chloride ion is called an anion. Its electron configuration is 1s2 2s2 2p6 3s2 3p6.
4.Ionic bonds are also formed when there is a large electronegativity difference between two atoms. This difference causes an unequal sharing of electrons such that one atom completely loses one or more electrons and the other atom gains one or more electrons, such as in the creation of an ionic bond between a metal atom (sodium) and a nonmetal

Balance the follwing equation:
BLANK C+ BLANK H(2) -> BLANK CH(4)
Everything in partnethesis are subscripts.
Thanks!
Answer:
- in order to balance the chemical equation, you need to make sure the number of atoms of each element on the reactant side is equal to the number of atoms of each element on the product side.
equation: (given)
__ C + __ H2 --> __ CH4
C = 1 | C = 1
H = 2 | H = 4
so, here we can see that the number of hydrogen (H) atoms are NOT equal, which means we have to put a number infront of the compounds inorder to balance it. this means putting a coefficient.
equation: (balanced)
C + 2H2 + CH4
- the only thing added was the 2.

Which indicates how evidence of climate change supports the theory of continental drift?
coal fields in several continents
volcano formation
glacial evidence found in South America
folded mountains in Africa and South America
Answer:
C glacial evidence found in America
Explanation:
The study of the rocks is called petrology.
The correct answer is C.
Continental drift is a theory that describes the same composition of rocks around the world.
According to this theory, it states that the different continent moves around the place and collide with the other continents.
For example the collision of the Indian region to current Asia.
Hence, the correct answer is C that is glacial evidence found in South America

Which agent most changes the earth's surface? O A. moving ice B. wave action O C. running water O D. tide action E. cloud movement
The correct answers are B. Clouds and D. Storm systems.
Explanation:
"Convection currents are the result of a physical-chemical process in which chemicals are heated and this decreases their density, causing their elevation. At the same time, the elements in the top sink because of lost temperature and increase in density, creating a cycle. According to the above, the correct answers are B Clouds and D. Storm Systems. Clouds are the result of a cycle of water, in which the water on the earth in a liquid state evaporates due to the caloric energy from the sun, changing to a gas state and go up until becoming droplets again in a process called condensation forming cloud. Once the cloud is very heavy and lost its temperature, it precipitates to the earth due to the force of gravity, and then the cycle starts again. Secondly, storm systems are a kind of cloud, those clouds develop vertically thanks to the convection process, in this, the same process occurs but the clouds have an internal air stream that makes that the clouds grow up vertically producing storms, those clouds are known as Cumulonimbus and Cumulus congestus. So, the correct answers are B. Clouds and D.Storm systems."
