Answer:
C) Platelets
Explanation:
Hemophilia is caused by a lack of clotting factors. Because platelets (or lack thereof) are what is responsible for how the blood clots, it can be reasonably inferred that the answer is C.
(Platelets secrete procoagualants, which are clotting factors. If there is a genetic issue with how these clotting factors work, then the platelets will not be useful.)
<span>When you are pregnant, you do not ovulate because you have already fertilized an egg and it is embedded into the uterus where it is growing into a baby. The body knows this, so it does not shed the uterine lining. The shedding of this lining is triggered by hormones which change when the body is pregnant. During pregnancy, a large amount of progesterone is initially produced which helps to prevent the lining from shedding. If you are not pregnant, your progesterone level will begin to decline at the end of your cycle, triggering the shedding of the lining and the period. Birth control pills alter your hormones to mimic a pregnant state. This will prevent the body from releasing an egg and then shedding the uterine lining.</span>
Science means to know. Biology is the study of living things.
You understand a lot more of the function of the body (EMT, healthcare, diseases, etc.)
animals (veterinary work,etc.) You will understand the intro into genetics, and the ways in which the sun and plants directly influences our entire world.
Biology is a form of science that is pretty broad, and at the same time a form of science you can use in every day life of understanding the basic things that happen around you (in culture, family, news, environment, behavioural, etc.)
Biology is also a great way to get your feet wet into basic science- a launching pad for chemistry, physics, etc. Hope this helped. :)
it only need one to fertilize a egg in a flower
