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.
Answer:
false
Explanation:
force=mass x acceleration
more mass means more force
Answer:
The correct answer is D.
Explanation:
The Amoeba Proteus example given in the question describing its engulfing smallar organism and digesting them is an example of a proces named "Phagocytosis". These cells are called phagocytes and the process can be used for both feeding purposes or defensive purposes by various cells. I hope this answer helps.
<span>None of the above. All of the following affect
metabolism at some point in an individual's life. As a person ages, metabolic
rate generally slows down because of muscle tissue loss, and some hormonal and
neurological changes. Gender also affects metabolism because men are generally
larger in size than women that is why they tend to have faster metabolisms than
women. Genes or inherited traits from parents also affect metabolism, the rate
at which the body goes is dependent on inherited traits from parents, also the
diseases that come with abnormal genes can affect metabolism. Temperature can also
affect metabolism because the body adjusts to maintain its normal temperature
which can either increase or decrease metabolic rate.</span>
