Answer:
Meiosis can be described as a process of cell division in which four daughter cells are produced and the chromosome number in the daughter cells gets reduced to half of the parent chromosomes.
In anaphase 1, the homologue chromosomes are pulled apart and they get pulled in the opposite reaction. The sister chromatids are not separated in anaphase 1.
In anaphase 2, the sister chromatids get separated. They move towards the opposite pole.
Answer:
<h2>Normal quiet expirarion of air is known as Tidal volume which is equal to 500 mL .</h2>
Explanation:
Normal quiet expiration or Tidal volume is a expiration of air with each normal breath . This is about 500 mL . It is composed of about 350 mL of alveolar volume and about 150 mL of dead space volume . The alveolar volume consist of the air that reaches the respiratory surface of alveoli and involve in gaseous exchange . The dead space volume consist of air that does not reach the respiratory surfaces . The lowest value is of Tidal volume . There is an extra amount of air that can be expired forcibly after a normal expiration i.e., known as expiratory reserve volume which is equal 1000 mL of air .
Answer:
Overexploitation and interactions between drivers Natural or human-induced factors that directly or indirectly cause a change in biodiversity are referred to as drivers. Direct drivers that explicitly influence ecosystem processes. include land use change, climate change, invasive species, overexploitation, and pollution.
Instead, they use uranium fuel, consisting of solid ceramic pellets, to produce electricity through a process called fission. Nuclear power plants obtain the heat needed to produce steam through a physical process. <span>This process, called fission, entails the splitting of atoms of uranium in a nuclear reactor.</span>
