Answer:
Afforestation and national sanctuaries are two measures each to conserve natural vegetation and wildlife.
Explanation:
The natural vegetation and wildlife restoration is one of the main concerns that are essential for the development and growth of a country's biodiversity. Due to human land-use changes and migration of people, from one place to another with their cattle, lands are becoming deserted and grassland and forest land are declining.
- So, we need to plant more trees that act as the natural habitat for the wildlife and preserve and conserve them in parks and sanctuaries which will help reduce the impacts of global warming and climate change.
- We should not kill any animal.
- We should decrease the use of plastics.
Answer:
Anterior lobe
Explanation:
The pituitary gland is made up of two distinct lobes: the anterior lobe and the posterior lobe. The anterior lobe secretes as many as seven different hormones. Some of the hormones secreted by anterior lobe are namely adrenocorticotrophic hormone, prolactin, gonadotropins, melanocyte-stimulating hormone, and thyroid-stimulating hormone. The posterior lobe releases only oxytocin and vasopressin in the bloodstream. These hormones are not produced by the posterior lobe but are only stored and released by it.
Answer:
b. vitamin K deficiency.
Explanation:
A normal bleeding time in association with normal platelet count, and increased prothrombin time (PT) and INR, is indicative of vitamin K deficiency.
This ultimately implies that, when an individual is suffering from vitamin K deficiency, he or she would experience increased bleeding.
Volcanoes and tectonic plates enrich land formation. When a volcanic eruption occurs, materials are brought to the surface that results in the formation of new islands. The actions of converging tectonic plates have created the most beautiful landforms and oceanic trenches. Also, eruptions better the soil quality in a given location. The mineral deposits emitted during an eruption is absorbed by the soil and becomes a lifelong source of nutrition.
