Answer: Option A.
The hypothalamus is the brain structure responsiblre for regulating thirst, hunger, temperature and sexual behaviour.
Explanation:
Hypothalamus is a part of brain structures located at the floor of the third ventricle below the thalamus and its control the autonomic system.
It controls hunger, thirst, temperature, fatigue, sleep and sexual behaviour . Hypothalamus secretes the anti diuretic hormones which increases the level of water absorbed into the blood by the kidneys and corticotropin releasing hormone which regulate immune system.
Answer:
The effects of climate change may be associated with the increased incidence of <em>V. vulnificus</em> infection
Explanation:
<em>Vibrio vulnificus</em> is a harmful bacterium that causes a serious disease due to eating contaminated seafood, which is the main cause of seafood-related deaths in the USA. <em>V. vulnificus</em> is naturally present in the flora of coastal waters around the world and this bacterium has been isolated from a variety of seafood (e.g.., fish, oysters, shrimp, etc). Epidemiologic studies have shown that the incidence of <em>V. vulnificus</em> infection has increased dramatically since 1996. During this same period, climate change has been responsible for the increase in salinity and temperature of the coastal waters (i.e., the natural habitat of this bacterium). In consequence, it is reasonable to suppose that the change in climatic conditions may be associated with the increased incidence of <em>V. vulnificus</em> infection.
<h2>Energy </h2>
Explanation:
Energy flows in only one direction through an ecosystem
- The Sun supports most of Earth's ecosystems
- Plants create chemical energy from abiotic factors that include solar energy and chemosynthesizing bacteria create usable chemical energy from unusable chemical energy
- The food energy created by producers is passed to consumers, scavengers, and decomposers
- Energy flows through an ecosystem in only one direction, it is passed from organisms at one trophic level or energy level to organisms in the next trophic level
- Most of the energy at a trophic level – about 90% – is used at that trophic level and organisms need it for growth, locomotion, heating themselves, and reproduction
- So animals at the second trophic level have only about 10% as much energy available to them as do organisms at the first trophic level
- Animals at the third level have only 10% as much available to them as those at the second level
Answer: The mass of carbon in the products is greater than the mass of carbon in the reactants.
