Answer:

The correct answer will be-pachytene, prophase I,

Explanation:

Tetrad is the structure formed during the meiotic type of cell division which produces four daughter cells.

The tetrad structure is seen under the microscope during the pachytene substage of prophase I.

The tetrad structure is formed when four sister chromatids are aligned together in a cell before the crossing over event or recombination has to take place. The tetrad formation allows the crossing over to take place in pachytene.

Thus, pachytene, prophase I is the correct answer.

Which situation is in equilibrium?

Orlov [11]

Answer:

The correct answer is: B. The amount of air in a room never changes.

Explanation:

A system is said to be in equilibrium when the net components in the system remains constant (no increase or decrease) with time.

The air in a room never remains constant and always undergoes dynamic movement into and out of the room. At equilibrium, the net air in the room remains constant as amount of air exiting the room is balanced by the amount of air entering it.
Evaporation of water in the form of water vapour from a cup into the atmosphere is not in a state of equilibrium as the amount of water evaporating from the cup is not replaced in the cup so there is a net decrease in water level in the cup.
The decrease in nitrogen percentage in a room is not in equilibrium as the nitrogen concentration of the room is not constant.
A blade of grass growing taller is not in equilibrium as a constant height of the grasses is not maintained.

Main features of Solar System, Main facts of solar system

iren [92.7K]

Answer:

The main features of the solar system:

The Sun is our nearest star.

The planets orbit the Sun.

The time taken to orbit the Sun increases with distance from the Sun.

Gravity keeps the planets in orbit around the Sun and the moons in orbit around their planets.

From the Sun, the order of the planets is Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. You might need to be able to recall this in the exam.

The planets go around the Sun in slightly squashed circular elliptical orbits.

Pluto is classified as a dwarf planet or planetoid. It has a highly elliptical or eccentric orbit.

Main facts

The definition of a planet and a moon is fuzzy. ...

Comets and asteroids are leftovers. ...

The planets are all on the same “plane” and orbit in the same direction. ...

We're nowhere near the center of the galaxy. ...

But the Solar System is bigger than you think. ...

The Sun is hugely massive. ...
