HELP!
Kryger [21]

Answer:

discovered moons around Jupiter and phases of Venus.

Explanation:

This is because Galileo was a scientist that discovered some proofs to back heliocentric theory. He discovered four moons in the orbit that surrond jupiter and he napped out how the medicean stars where rightly positioned even at night. They would not orbit around Jupiter if the Earth was at tye center of the system. Venus is very close to the sun and it won't go through phases of the Earth is at the system's center.

Heliocentric theory indicate the sun being the centre of the system.

When using the periodic table explain how you can create a model of an element you may be investigating?
Anvisha [2.4K]

Answer:

<h3> I have many answers</h3>

<h3>1 The Periodic Table can predict the properties of new elements, because it organizes the elements according to their atomic numbers. ... They hope that the two nuclei at the centre of these atoms will fuse and form a heavier nucleus. When these heavy elements form, they are usually highly unstable</h3>

<h3>2 Periodic Trends Can the properties of an element be predicted using a periodic table? ... It includes information about atomic masses and element symbols, but it can also be used to make predic- tions about atomic size, electronegativity, ionization energies, bonding, solubility, and reactivity.</h3>

<h3>3 The periodic table is arranged in rows and columns in which the elements have similar properties. ... You can also predict which elements will combine with others, and in what ratios, because the number of electrons in the shells can be deduced.</h3>

Hummus is an important component of healthy soil. how does hummus form?
denis23 [38]

Answer:

Humus (hummus) is a dark organic matter in the soil which is produced by the decay of leaves or twigs (leaf litter). The litter is decayed in the soil by the action of microbial communities and chemcial reactions (together called as biogeochemical reactions). This process is also known as decomposition. The higher humus content in the soil makes it more fertile because there are more nutrients releasing due to increased turnover of the decomposing bacteria. Further, humus formation is increased if more water (moisture content) and oxygen is available.
