Answer:

Iron is a lustrous, ductile, malleable, silver-gray metal (group VIII of the periodic table). It is known to exist in four distinct crystalline forms. Iron rusts in damp air, but not in dry air. It dissolves readily in dilute acids.

When a rat's ventromedial nucleus is destroyed, the rat will:
ExtremeBDS [4]

The correct answer is C. It continues to eat the amount of food it does normally.


When rat's ventromedial nucleus is destroyed the rat will become more hyper physics and it continues to eat until it has doubled its normal weight.

Ventromedial nucleus of hypothalamus is termed as nucleus of hypothalamus.

It is a distinct morphological nucleus which involved in terminating hunger, fear, sexual activity and thermoregulation.

Ventromedial nucleus of hypothalamus is divided into subdivisions. For example, dorsomedial, ventrolateral, central and anterior. VMN is most commonly associated with satiety. In rats ventromedial nucleus is caused by over-eating and obesity.

inn [45]

Answer;

A.) a law

Explanation;

-A law is a statement based on repeated experimental observations that describes some phenomenon of nature. Proof that something happens and how it happens, but not why it happens.

- A Theory is a well-substantiated explanation acquired through the scientific method and repeatedly tested and confirmed through observation and experimentation.

-A Hypothesis is a proposed explanation for a phenomenon made as a starting point for further investigation.

an organism that uses that uses hydrogen sulfide as a source of energy is categorized as which of the following ​
Shkiper50 [21]
In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic compounds (e.g., hydrogen gas, hydrogen sulfide) or methane as a source of energy, rather than sunlight, as in photosynthesis. Chemoautotrophs, organisms that obtain carbon through chemosynthesis, are phylogenetically diverse, but also groups that include conspicuous or biogeochemically-important taxa include the sulfur-oxidizing gamma and epsilon proteobacteria, the Aquificae, the methanogenic archaea and the neutrophilic iron-oxidizing bacteria.

Many microorganisms in dark regions of the oceans use chemosynthesis to produce biomass from single carbon molecules. Two categories can be distinguished. In the rare sites at which hydrogen molecules (H2) are available, the energy available from the reaction between CO2 and H2 (leading to production of methane, CH4) can be large enough to drive the production of biomass. Alternatively, in most oceanic environments, energy for chemosynthesis derives from reactions in which substances such as hydrogen sulfide or ammonia are oxidized. This may occur with or without the presence of oxygen.

Many chemosynthetic microorganisms are consumed by other organisms in the ocean, and symbiotic associations between chemosynthesizers and respiring heterotrophs are quite common. Large populations of animals can be supported by chemosynthetic secondary production at hydrothermal vents, methane clathrates, cold seeps, whale falls, and isolated cave water.

It has been hypothesized that chemosynthesis may support life below the surface of Mars, Jupiter's moon Europa, and other planets.[1] Chemosynthesis may have also been the first type of metabolism that evolved on Earth, leading the way for cellular respiration and photosynthesis to develop later.

That’s probs to much
