Answer:

Explanation:

When there is difference between the concentration of the content of a cell and the solution surrounding the cell, there will be an Electrochemical gradient or Concentration gradient. Therefore, some solute will tend to move from the region of high concentration to the region of lower concentration through the cell membrane.

Such a movement is called Primary Active Transport

Answer: the membrane transport used is "facilitated diffusion"

Explanation:

Facilitated diffusion transport (passive transport) is a spontaneous transport of molecules or ions across a biological membrane via membrane Proteins that act as mediators. These membrane Proteins (transporters or permeases) speed up the movement of solutes across the membrane by facilitating diffusion.

Sodium ion, glucose ions and some other ions need to be transported across d plasma membrane which is made of lipid bilayer that is impermeable. For this transport to occur, a mechanism of bypassing or creating an alternative path across the plasma membrane is needed. This mechanism is performed by permeases(membrane proteins).

The membrane proteins act as transport facilitator by lowering the activation energy for effective transport of polar compound and ions.

PLEASE ANSWER ASAP- In the solid state, how does Water compare to Neon and Argon? Why do you think they act differently?
alekssr [168]
Neon and Argon are known as the noble gases. This means that there inert and don’t typically react. The noble gases have full outer shells and therefore satisfy the octet rule. Hydrogen, on the other hand, must lose an electron to become stable. That is why it reacts.

11. What are transition metals?
kolezko [41]

Answer:

Elements that fall between those on the left and right sides of the periodic table

Explanation:

Transition metals:

These are present at the center of periodic table.

These are d-block elements.

They include the elements of group 3 to 12 in periodic table.

They have large charge to radius ratio.

They mostly form paramagnetic compounds.

They shoes more than one oxidation state.

They form colored compounds.

They all have high melting and boiling point.

They have high densities.

They form stable complexes.

The elements of f-block are also transition but they are called inner transition.These are consist of two series lanthanide and actinides.

I don’t know if it’s that one or not
Sphinxa [80]

Answer:

I think is the last one.

Anthracite – Stage Four

Anthracite, the fourth stage in coal formation, is also known as “hard coal” because it is hard and has a high lustre. It appears to have been formed as a result of combined pressure and high temperature. Anthracite burns with a short flame and little smoke.

Which of the following is not a true statement? a. oxiranes are three-membered ring ethers. b. oxetanes are five-membered ring e
AURORKA [14]

The true statement will be "oxetanes are <u>five-membered ring</u><u> </u><u>ethers."</u>

The four-membered ring of octane, a saturated organic heteromonocyclic parent, contains three carbon atoms but one oxygen atom. It belongs to the family of oxetanes well and has a saturated organic heteromonocyclic parent.

Oxetanes can also be widely employed as monomers inside the cationic or anionic synthesis including both branched but also linear poly-ethers. Thermal decomposition, photolysis, as well as cycloaddition are further beneficial reactions.

The structure of oxetanes are shown as:

The Patern-Büchi reaction is another process that could result in the formation of an oxetane ring. In addition to decarboxylation of such a six-membered cyclic carbonate, diol cyclization can also create the oxetane ring.

a)Oxiranes has two carbon ring with one oxygen.

b) Oxetanes has 3 carbon ring with one oxygen

c) Dioxanes has six membered ring with two oxygen.

Therefore, the true statement will be "oxetanes are five-membered ring ethers."

Hence, the correct answer will be option (b)

Please begging you guys someone help me
BaLLatris [955]

Answer:

See Explanation

Explanation:

10) From the options provided for this question, gamma particle is the most energetic. Recall that gamma rays are high energy electromagnetic radiation which are capable of causing a high degree of ionization in matter.

11) The bombardment of U-235 with neutrons leads to the reaction;

U\frac{235}{92}  + n\frac{1}{0}---> I\frac{138}{53}  + Y\frac{95}{39} +3n \frac{1}{0}

Hence

a = 92, b= 95, c= 53

12) In positron emission, a proton is transformed into a neutron. The mass number of the daughter nucleus is the same as its parent but the atomic number decreases by 1.

Hence;

Th\frac{231}{90} -----> e\frac{1}{0} +Ac \frac{231}{89}
