Animals need control mechanisms to do things without thinking. They digests food, breath and walk without thinking about things completely.
There are no clinical situations I can imagine that would require the hormonal IUD and birth control pills. Taken together, they are providing more progestin than is required to prevent pregnancy or reduce menstrual bleeding. Contact your health care provider for advice specific to your situation.
Passive mechanisms refer to systems that respond automatically and do not require external energy input to operate. These mechanisms rely on physical properties such as shape, material, or gravity to perform their function without active control. Examples include a door closing due to gravity or a see-saw balancing based on the distribution of weight.
I think you need to educate yourself about the methods of birth control. "Allergy" to all hormonal methods is unheard of, but if it is so, herbal options are not likely to be easier. Remaining methods are natural family planning, abstinence, and barrier methods such as condoms, vaginal sheath, diaphragm, cervical cap, and contraceptive sponge. These methods are less effective than other options, and require you to follow directions exactly.
No, animals do not require a generator for regeneration. Regeneration is a natural process that some animals have the ability to perform, allowing them to replace lost or damaged body parts. This process is controlled by the animal's own biological mechanisms and does not involve the use of a generator.
If you are taking birth control and are unknowingly pregnant, the effects on the fetus can vary depending on the type of birth control used. Hormonal contraceptives, such as the pill or patch, are generally considered safe in early pregnancy, but it's best to consult a healthcare provider for guidance. Non-hormonal methods, like copper IUDs, may require removal if pregnancy is suspected. Always seek medical advice if you believe you might be pregnant while on birth control.
Active transport mechanisms, such as the sodium-potassium pump in cell membranes, require energy in the form of ATP to move substances against their concentration gradient. Endocytosis and exocytosis, which involve the uptake and release of large molecules or particles by cells, also require energy.
No. The nodes are automatic. They start the pulses by themselves. This is called an automatic pacemaker. They have no external nerve or hormonal control.
Yes. All animals require oxygen.
All living things require water. Humans require it and so do animals.
Animals require higher rate of respiration as they move from one place to another and therefore they need more energy. There the rate of respiration in animals is than in plants. They require more enrgy.
All animals need oxygen to live.
No. That would require hormonal treatments and/or surgery.
