The defination to energy is B) the ability to create a new substance.
Answer:
The endometrium is the mucous layer that lines the uterus internally. Its function is to thicken during the menstrual cycle to allow the embryo to implant and a pregnancy can take place.Two phases of the endometrial cycle are distinguished: the proliferative phase and the secretory phase. The proliferative endometrium occurs due to tissue regeneration on the first day of the menstrual cycle, where, thanks to the production of estrogen in the ovary, cell multiplication occurs, giving rise to the endometrial glands and more blood vessels.
Explanation:
The first phase, known as the follicular phase, begins on the first day of menstrual bleeding and lasts for about two weeks. During this period, one of the ovules - which are the female reproductive cells - grows and matures within an ovary. At the same time, the ovaries produce hormones that promote the development of the lining of the uterus, called the endometrium. The lining of the uterus, the endometrium, thickens in response to estrogen stimulation, that is, over the days, the endometrium becomes thicker and rich in blood vessels, preparing to receive the egg the moment it is expelled from the ovary. When the ovum matures, around day 14 of the cycle, it separates from the ovary - the ovulation process - and slides down the fallopian tube to the uterus.
Answer:
Rough Endoplasmic reticulum.
Explanation: The rough ER is a type of Endoplasmic reticulum which has ribosomes in the form of protein attached to it. And it helps in detoxification of the toxins.
Answer:
Satellite imagery and aerial photography have proven to be important tools in support of mineral exploration projects. They can be used in a variety of ways. Firstly they provide geologists and field crews the location of tracks, roads, fences and inhabited areas.
Explanation:
Answer:
1. Ends of the respiratory branches are called alveoli.
2. C. To control blood flow to different areas of the body depending on activities
Explanation:
1. The trachea divides into left and right primary bronchi which in turn divide multiple times upon entering the lungs and make the bronchial tree.
The final branches of the bronchial tree are the terminal bronchioles that lead to alveoli. The alveoli are the balloon-shaped structures and serve as the site of gas exchange between the blood and inhaled air.
2. The opening and closing of sphincters of capillary beds regulate the direction of blood flow. The opening of sphincters allows the blood to flow into associated branches of capillary beds while closed sphincters direct the blood from arterioles to venules via thoroughfare channel.
This local change in blood flow is responsible for the autoregulation of blood flow to different tissues to match their respective metabolic demands. For example, during physical activity, more blood is directed to skeletal and cardiac muscles.
