Answer
This fossil was an organism that has been turned into rock.
Explanation:
I just took the test and got it right :D hope this helps!!
Answer:
The correct answer will be option-C.
Explanation:
Hypothalamus is a part of the brain which controls many important functions of the body by producing hormones.
When the amount of water gets reduced in the blood, it leads to a change in the osmolarity which can be easily detected by the osmorecpetors present in the neurons of the hypothalamus.
In response, neurons secrete Anti-diuretic hormone in the blood which acts in the tubules of the kidney where they help in re-absorption of the water from the body.
Thus, Option-C is the correct answer.
Sounds like Your cardiovascular system, the closed tubes must be your blood vessels, siencey term: your Angio, which means blood vesels
Answer:
Sun energy >>> Grass >>> Mouse >>> Fox >>> Puma/Mountain Lion>>>Microorganisms.
Explanation:
Organisms that can synthesize inorganic substances, such as light, and turn it into food according to their own needs are <u>producers</u>, and they are called autotrophic organisms. These organisms are by excellence all plants, that photosynthesize. Organisms that are incapable of producing their food are called heterotrophic. They depend on other organisms from the trophic chain such as plants or other animals to feed on, so they can get proteins and energy. In the trophic chain, heterotrophic organisms occupy the first, second, or third consumer level, after producers.
The trophic web is the process of energy transference through a series of organisms, in which every organism feeds on the preceding one and becomes food for the next one. The first link is an autotroph organism or producer, such as a vegetable, that can synthesize organic matter from inorganic matter. The next links are the consumers: herbivores are primary consumers and feed on producers. Carnivores are secondary consumers and feed on herbivores, and so on. The last links are the decomposers, microorganisms that act on dead animals degrading organic matter.
In the exposed example of a food web for Grassland, we can differentiate:
- Producer: Grass. An autotrophic organism that synthesizes organic matter from the sun energy. These species reproduce sexually and produce seeds for dispersion. These seeds are also an important source of food for many animals.
- Herbivores (Primary consumer): Mouse. A heterotrophic animal that feeds on the seeds of the grasses.
- Carnivore (Secondary consumer): Fox. A carnivore heterotrophic animal that hunts mouses and feeds on them.
- Carnivore (Tertiary or superior consumer): Puma/Mountain lion. A superior consumer, carnivore heterotrophic animal that hunts foxes and feeds on them.
- Decomposers: Microorganisms. When the puma dies, these organisms degrade the animal´s organic matter
Answer: d. None of the above is false.
Explanation: The reasons are:
Intermolecular forces should be reduced when molecules need to be vaporized, otherwise they will not be converted into vapours.
When the temperature increases, forces of attraction decreases which allows molecules to evaporate because energy will be increased which allows molecule to break bonding between them. Hence increasing temperature has effect on vaporization.
Dispersion forces is the weakest force between molecules and hydrogen bond is strong so molecule having only dispersion force will evaporate at the higher rate.
