In meiosis, cell division will occur two times. It shall be called Meiosis I and Meiosis II. And Meiosis happens to our sex cells, egg for female and sperm cells for the male. There four stages in Meiosis I, Prophase I will happen when who homologous chromosomes exchange DNA. Metaphase I will happen when the pair move together in the center. Anaphase I is when the who homologous chromosomes are pulled apart to opposite poles. Telophase I is when the the first division of the chromosomes happen. Producing two 24 chromosomes cells. The nest division will produce haploid or 12 chromosome cells. In Propase II, the nuclear walls will disappear once again, in the Metaphase II the cells will meet again in the center. In Anaphase II the chromatids will be pulled apart. And then lastly in the Telophase II, the chromatids will not be 2 haploids. So in Meiosis, 4 sex cells are produced.
Atoms bound together and form molecules. Molecules are a little more complex than atoms. For example water is composed of two hydrogen atoms and one oxygen atom which are both gases. Properties of oxygen and hydrogen are completely different than water molecules.
Answer:
The process that is used by producers to make glucose is called photosyntheis and the chemical process used by both producers ans consumers to make ATP ito contribute to the energy exchange is called cellular respiration.
Explanation:
Photosynthsis
Photosynthesis occue in the mesophyll tissue present in leaves of plants .During photosynthesis the green plants or producers acquires CO2 from the atmosphere and utilizes water in presence of sunlight to produce glucose molecules along with the liberation of oxygen gas.
Cellular respiration
During cellular respiration the glucose molecules are oxidized to form energy in form of ATP along with the production of water and carbon dioxide.
The O2 that formed during photosynthesis is inhaled by human beings for respiration whereas the CO2 that is produced as waste material inside our body is exhaled by us in the atmosphere.The CO2 is then used by the green plants to carry out photosynthesis.
Explanation:
mitochondria is a double membrane bound cell organelle,oval or cylindrical in shape.
<h3 /><h3>function</h3>
- regulate calcium ions in cells
- formation of yolk
- help in synthesis of photosynthetic pigments
- can synthesize store and distribute energy in the form of ATP whenever required
