Answer:
B. A biodiverse ecosystem harbors many interactions, thus a disturbance may impair some interactions, but not all.
Explanation:
Biodiversity is the variation of life forms in an environment. This is as a result of available nutrient and energy to support the various life forms.
- The relationship between biodiversity and rebound from disturbance is such that a biodiverse ecosystem is able to resist any change.
- The disturbance might affect proportion of the populace. But on the long organisms can survived and be propagated again.
Answer:
Estrogen and progesterone are both involved in preparing the endometrium for embryo implantation. Estrogen helps to ensure conception by increasing the amount of secretory glands in the uterus. Estrogen also increases blood supply to the endometrium.
Progesterone is crucial for embryo implantation and maintenance of pregnancy. Progesterone also enlarges secretory glands that produce carbohydrates, proteins and mucin that are required for embryo nourishment before implantation. Progesterone stabilizes endometrial muscles to prevent them from contracting during pregnancy.
Explanation:
- Estrogen and progesterone are steroid hormones of the reproductive system. Estrogen helps in conception whereas progesterone maintains pregnancy.
- Estrogen is secreted during the follicular phase of the menstrual cycle that promotes the growth and maturation of follicles in the ovary.
- Estrogen also induces oestrous behavior in females.
- Secreted by the corpus luteum, progesterone is also a steroid hormone, responsible for implantation of the embryo in the uterus.
The answer would be used batteries. You would be able to recycle the vegetable waste within fertilizing and/or throw it away safely by disposing it in a trashcan since it is not a hazard towards the environment. As for aluminum cans, they are recyclable and are easy to use again once it is filtered through the system. However, batteries are NOT recyclable nor easy to dispose because they can release Alkaline which can harm the environment.
Answer:
c. increase HDL levels
Explanation:
Cholesterol is carried in blood in two ways, LDL and HDL. Both of them are lipoproteins made of fat and protein. LDL or Low Density Lipoprotein has 50% cholesterol and 25% protein by weight. HDL or High Density Lipoprotein has 20% cholesterol and 50 % protein. LDL carries cholesterol to arteries and deposits it there which is not good for the body. HDL on the other hand removes excess cholesterol from body via liver.
Aerobic exercise increases HDL values and lowers LDL values. It has been shown that exercising regularly can increase HDL level by 6% which is good for the overall health of the body. For maximum effect 30 minutes of moderate exercise should be done 5 times a week.
