Answer:
The correct answer will be the cell is in prophase I of meiosis and will enter metaphase I next.
Explanation:
Meiosis is a type of cell division which is involved in the formation of haploid gametes.
During meiosis the division of the genetic material is markedly observed and based on this meiosis is divided into 4 phases: prophase, metaphase, anaphase and telophase.
During prophase: the chromatin structure of DNA starts condensing to form chromatids which attaches to homologous chromatids and are known as sister chromatids. These sister chromatids exchange their genetic material via a process called called recombination or crossing over which takes place during pachytene stage of prophase I. After crossing over it is proceeded by the next stage that is metaphase I in which chromosomes gets aligned at the center of the cell.
Thus, the cell is in prophase I of meiosis and will enter metaphase I next is the correct answer.
Answer:
Myosin
Explanation:
Myosin are the major components of both muscle and non muscle cells in striated muscles which is responsible for contraction or movement that convert chemical energy (ATP) into mechanical work thereby generating force and movement.
During cellular movement , myosin filament will be the ones that are responsible for attaching and pulling the other filaments along because Myosin binds to actin at a binding site on the globular actin protein,it also have ATP binding sites which hydrolyses ADP to ATP , ATP binding causes myosin to release actin, which make actin and myosin to detach from each other thereby causing attachment and contraction of other filaments
b. 10% of energy is transferred from the first to the second trophic level.
Explanation:
In trophic level flow of energy is one way, only a small amount of energy get transferred with the organism. A large amount of energy gets dissipated in life processes like respiration, reproduction and digestion. The energy is also released as waste product. Thus, only ten per-cent of the total energy is present in the organism.
The energy transfer does not depend on the number of trophic levels.
Each trophic level receives the 10% energy from the previous trophic level as when algae is eaten by flagship.
Explanation:
Cave lions, sabre-toothed cats, cave bears, giant deer, woolly rhinoceroses, and woolly mammoths were prevailing species of the Quaternary period. Without the dinosaurs, plant life had an opportunity to flourish during the Cenozoic era.
Answer:
Animals preserve play very important role in maintaining ecosystem biodiversity. In animal preserves, animals are protected from the harmful effects of the changes which occur in the environments due to human intervention. In animal preserves,
animals should be kept in proper environment and provide a proper place for living and food in order to increase the population of the animals.
