The theory of evolution through the process of natural selection was only gradually accepted because: the theory challenged the idea that God made all animals and plants that live on Earth (creationism) there was insufficient evidence when the theory was published to convince many scientists.
I think it’s winter because the southern hemisphere is tilted away from the sun, if I’m looking at that right.
<u><em>WHAT HAPPENS TO OUR BODIES WHEN WE EXERCISE?</em></u>
<u><em /></u>
What is happening to her circulatory system?
When you exercise, or play football in this case, you are working your muscles and certain places in the body. When this happens, your muscles respire (burn the <u>FOOD</u> to produce <u>ENERGY</u>) more faster than they would normally, so the demand for <u>OXYGEN</u> and <u>GLUCOSE</u> is increased.
As the muscles are performing cellular <u>RESPIRATION</u> quicker than the norm, they need oxygen and glucose to reach them faster (glucose and oxygen are the components for cellular respiration), and also they need to get rid of their <u>CO2</u><u> </u>(products of cellular respiration are <u>CARBON DIOXIDE</u> and <u>WATER</u>) so the <u>HEART</u> is now pumping blood around the body at a faster rate in order to provide these cells with what they need. To summarize, the circulatory system has to work harder and faster during exercise to provide the cells at work with glucose and oxygen and to get rid of the waste carbon dioxide.
What is happening to her breathing system?
<em>{Relates to explanation given} </em>The requirement for oxygen is increased so now the respiratory system (in particular the <u>LUNGS</u>) have to work harder and faster to take in more oxygen and to exhale more <u>CO2</u>, thus you begin to breathe faster. To summarize, oxygen is inhaled quicker and carbon dioxide is exhaled quicker, therefore the rate of <u>DIFFUSION</u> is increased.
Diagram:
Draw picture of a girl playing football and then in the nest picture of her lungs and heart, you can also include arteries and the veins. Show how the lung and the heart work more harder during the exercise or when playing any sports

Answer:
<h2>Lytic cycle: involve that there is rupture( lysis) of the host cell and release many copies of virus.
</h2><h2>Lysogenic cycle: involve the insertion of the nucleic acid of a bacteriophage into host genome, known as prophage.
</h2>
Explanation:
There are many similarities and differences between lysogenic and lytic cycles that;
1. Lysogenic cycle of bacteriophage :
i) in lysogenic cycle: bacteriophage insert its DNA with that of a host, known as prophage and it replicates with host.
2. Lytic cycle of bacteriophage:
i) lytic cycle is that it results in many copies of the virus very quickly and the cell is ruptured and many copies of virus are released.
4. Similarity is that in both cycles bacteriophase inter into the host and use their machinery.
