G0: Resting state. Given only when the cell is not prepared to divide. It takes place at the end of the G1 phase.
G1 checkpoint: It takes place in the same moment as the G0, this is a check for nutrients, growth factors (molecular signs), and DNA integrity.
G2 checkpoint: It takes place at the end of the G2 phase, to check if the cell size is correct and the DNA replication was correctly done.
Metaphase checkpoint: At the end of the metaphase. Here is checked the chromosome spindle attachment and chromosome alignment to the equatorial plate.

Have the discoveries of the extrasolar planetary systems confirmed the nebular hypothesis predictions?
Answers
The discoveries of the extrasolar planetary systems can confirm nebular hypothesis predictions, as the nebular hypothesis said that there are still remaining planets present that are undiscovered.
What is a nebular hypothesis?This hypothesis states that the Sun and all of the planets in our Solar System were originally part of a vast cloud of molecular gas and dust that collapsed some 4.57 billion years ago due to some terrible event.
Therefore, the nebular hypothesis predicted that there are still additional planets present that have not yet been identified, and the findings of the extrasolar planetary systems can corroborate those predictions.

B. What features of the geosphere could affect ecosystems?
Answers
Explanation:
1: A) is a purposeful unit that outcomes from interactions of abiotic, biotic, and anthropogenic components and are a combination of interacting, interrelating parts that shape a unitary whole. Ecosystems differ in size. They can be as small as a puddle, or as large as the earth itself. Basically, any dwelling and non-living matters interacting together can be considered an ecosystem. Within each ecosystem, there are habitats that differ in size. A habitat is a area the place a population lives. A populace is a group of residing organisms of the identical variety dwelling in the identical location at the same time. Natural ecosystems are made up of abiotic elements such as air, water, rocks, and power and biotic elements such as plants, animals, and microorganisms.
1: B) Faster plate tectonic movements additionally suggest more mountains are developed in areas the region plates converge. As rocks are uplifted into mountains, they start to erode and dissolve, sending sediments and vitamins into waterways and impacting the ecosystems for living things.

Answers
The day-to-day change in the temperature of air on the Earth is controlled by the energies which are received and lost from the surface of the planet.
What is temperature change?
During summers, the sunrays hit Earth at a very steep angle. The sunlight does not spread out as much, thus increasing the amount of energy which is hitting any spot. Also, the long daylight hours allows Earth time to reach the warm temperatures.
The daily air temperatures at Earth's surface are in control of the incoming and outgoing energies. During the day, the temperature of air increases as energy gain exceeds the energy lost from the surface of Earth. And throughout the night, the air temperature decreases as the surface of Earth loses more energy than it receives.
