Given what we know about the mechanisms surrounding the biological movement of substances, we can confirm that when two substances in a secondary active transport move in the same direction, it is called a symport.
A secondary active transport harnesses the electrochemical energy generated by its movement of one substance, to aid the movement of the other. These movements can be of two types, depending on the directions:
AntiportSymportAn antiport transport will move both substances in opposite directions, meaning one out of the cell and one into the cell. The transport described in the question is that of a symport, given that it moves both substances in the same direction.

In chemical compounds, covalent bonds form when -
a. the electronegativity difference between two atoms is very large
b. electrons are completely transferred between two metals
c. pairs of electrons are shared between two nonmetal atoms
d. two nonmetal ions are attracted to each other by opposite charges
Answer:
c. pairs of electrons are shared between two nonmetal atoms
Explanation:
Bonding between elements solely depends on their electronegativity. When there is large difference in electronegativity, those atoms form ionic bonds. Covalent bonds form when the difference is minimal, or none at all. When the difference between electronegativities is 0 or very close to 0, then they form pure covalent bonds, or nonpolar bonds. An example of this are diatomic molecules. Diatomic molecules are two of the same atom that form nonpolar covalent bonds because their electronegativy difference is 0, as they have the same electronegativity. When the electronnegativties have bit of difference, they form polar covalent bonds.

A sample of a gas in a 4L container at 300K has a pressure of 1 atm. If the
temperature is increased to 600K and the volume is decreased to 2L , the
pressure is likely to be closest to which of the following? *
O 0.5 atm
1 atm
4 atm
2 atm
The final pressure of the gas in the container is 4 atm
From the question given above, the following data were obtained:
Initial volume (V₁) = 4 L
Initial temperature (T₁) = 300 K
Initial pressure (P₁) = 1 atm
Final temperature (T₂) = 600 K
Final volume (V₂) = 2 L
Final pressure (P₂) =?Using the combine gas equation, we can obtain the final pressure of the gas as illustrated below:[tex]\frac{P_{1} V_{1} }{T_{1}} = \frac{P_{2} V_{2}}{T_{2}}\\\\\frac{1 * 4}{300} = \frac{P_{2} * 2}{600} \\\\[/tex]
Cross multiply
300 × 2 × P₂ = 4 × 600
600 × P₂ = 2400
Divide both side by 600
[tex]P_{2} = \frac{2400}{600} \\\\[/tex]
P₂ = 4 atmTherefore, the final pressure of gas is 4 atm.

Which has more momentum?
A: the 0.5 kg tennis ball
B: the 2 kg basketball
C: the 5 kg bowling ball
D: the all have the same momentum
Hurry!!! Only got a couple mins!!!
The momentum of the bowling ball will be greater than the rest balls.
The correct answer to the question is Option C. The 5 kg bowling ball
Momentum is defined as the product of mass and velocity i.e
Momentum = mass × velocity
If we keep the velocity of the object constant, the momentum will depend on the mass of the object.
Thus, the higher the mass, the greater the momentum and the lesser the mass, the smaller the momentum.
From the question given above,
Mass of tennis = 0.5 Kg
Mass of basketball = 2 Kg
Mass of bowling ball = 5 kg
We can see that the bowling ball has a higher mass.
Therefore, the momentum of the bowling ball will be greater than the rest balls.
The correct answer to the question is Option C. The 5 kg bowling ball

A gas of hydrogen atoms will create an absorption line spectrum if it is between you (telescope+spectrograph) and a continuum light source, and also an emission line spectrum if considered from a distinguishable angle.
When The emission spectrum of atomic hydrogen has been divided into several spectral sequences, with wavelengths given by the Rydberg formula.
These experimental spectral lines are due to the electron-making transitions between two energy positions in an atom.

What was the main reason why Alfred Wegener's theory about the movement of the continents was dismissed in 1912?
His theory explained the Earth was expanding as the plates moved
He didn't know about plate tectonics to explain how the plates moved
His map of the ocean floor did not support his theory
His theory was the first to observe the continents fit together
Answer:
His map of the ocean floor did not support his theory
Explanation:
Alfred Wegner was a great scientistHe observed the plate tectonics of earth and described it in a theory.It was dismissed after viewing his ocean floorAnswer:
He didn't know about plate tectonics to explain how the plates moved
Explanation:
Wegener believed the continents had pushed through the ocean floor. However, he did not have a satisfactory explanation for how this happened. There was no known source of energy large enough to move continents through the sea floor. Also, although scientists had data about the interior of Earth from earthquakes, there were no clues in Earth's crust to show that the continents had broken through the sea floor. Given this lack of evidence to explain the mechanism of continental drift, scientists did not accept this idea.
