Answer:
The answer is: a. Climacteric
Explanation:
Climacteric is the time in the midlife of a woman that starts with the diminution in ovarian activity (less production of estrogen and progesterone) until the end of ovarian function. It is the compilation of gradual changes of ovarian function that happen before the menopause (cessation of menses) and continue for a while.
The phases of the climacteric are pre-menopause, menopause and post-menopause. During the pre-menopause, hormonal changes will take place, there is a decrease in estrogen and progesterone production.
Answer:
b, d, f, a, e, c
Explanation:
Ca+ binds to troponin -> Troponin removes tropomyosin from G actin -> Myosin binds to actin -> Myosin generates a power stroke -> the sarcomere shortens -> ATP recharges the myosin head
The statement above is FALSE.
When a particular specie in an ecosystem is endangered, other species that interact with it will be negatively affected and the ecosystem may be throw out of balance. This is because all the components of the ecosystem depend on one another for survival.
Answer:
carbon dioxide- burning of fossil fuels
fluorinated gases- industrial processes
methane- production and transport of oil and natural
gas
nitrous oxide- agricultural and industrial activities
Explanation:
Greenhouse gases are gaseous components that induces greenhouse effect. This means that due to their structural ability to trap heat energy in the atmosphere, they contribute to the global warming effect on the Earth. However, this greenhouse gases are produced in large amounts as a result of the day-to-day anthropogenic activities. The following are the greenhouse gases and how they are produced.
Carbondioxide (CO2)- Carbondioxide is the most common and important greenhouse gas. It is generated via natural processes like respiration but also produced when fossil fuels e.g coal, petroleum etc. are burned.
Fluorinated gases- This is another greenhouse gas caused by activities of man. Fluorinated gases are produced in industries during the production of certain products.
Methane- Methane is a gaseous hydrocarbon and the principal constituent of natural gas. Therefore, the production and transportation of oil and natural gases can lead to the escape of methane into the atmosphere.
Nitrous oxide- Nitrous oxide is an oxide of nitrogen. It is mainly produced via agricultural processes such as nitrification and denitrification or use of fertilizers etc. and also industrial actions.
Both population health and public health can include very narrow or very large groups of individuals – some public health initiatives encompass entire countries or regions of the world – and both increasingly rely on digital data assets to identify patterns and aid workers as they address critical wellness needs.
