Why is it incorrect to say the insulation 'keeps out the cold'
Sonja [21]
Because technically there is no such thing as cold
all that exists is heat
this is because heat is the rapid movement of particles, made by friction (to understand why you must delve into physics and some chemistry)
so, when you feel cold, it's really the absence of heat
so instead of "keeping the cold out", which makes no sense at all scientifically, insulation keeps the heat in.

as a side note
the feeling of cold is produced when you come in contact with an object (yes, air counts) that has less heat, or energy, than you do, You feel cold because heat (energy) from your body is being transferred to the environment. This ABSENCE OF HEAT in your body is why you feel cold

How does the word mutualism relate to the world we live in? (biology)​
Pepsi [2]
Mutualism describes the ecological interaction between two or more species where each species has a net benefit.[1] Mutualism is a common type of ecological interaction. Prominent examples include most vascular plants engaged in mutualistic interactions with mycorrhizae, flowering plants being pollinated by animals, vascular plants being dispersed by animals, and corals with zooxanthellae, among many others. Mutualism can be contrasted with interspecific competition, in which each species experiences reduced fitness, and exploitation, or parasitism, in which one species benefits at the "expense" of the other. Mutualism is often conflated with two other types of ecological phenomena: cooperation and symbiosis. Cooperation refers to increases in fitness through within-species (intraspecific) interactions. Symbiosis involves two species living in proximity and may be mutualistic, parasitic, or commensal, so symbiotic relationships are not always mutualistic.

Mutualism plays a key part in ecology. For example, mutualistic interactions are vital for terrestrial ecosystem function as more than 48% of land plants rely on mycorrhizal relationships with fungi to provide them with inorganic compounds and trace elements. As another example, the estimate of tropical forest trees with seed dispersal mutualisms with animals ranges from 70–90%. In addition, mutualism is thought to have driven the evolution of much of the biological diversity we see, such as flower forms (important for pollination mutualisms) and co-evolution between groups of species.However, mutualism has historically received less attention than other interactions such as predation and parasitism.

The element is found in smaller quantities in the body but in a wider variety of places including ATP molecules, DNA, bones, and
NISA [10]

Answer:

Phosphate

Explanation:

  • Phosphorus is the element that makes up less than 1 percent weight of a human's body. However it is present in the ATP, DNA, teeth and bones in excessive quantity.  In the DNA molecule, phosphorus is present in the form of units phosphate molecules joined with nitrogenous bases and sugar groups in a successive fashion.
  • Moreover, there is energy currency of a cell called ATP that is important to perform normal day to day activities. it also contains phosphorus in the form of phosphate.
  • Moreover, bones and teeth are made up of Calcium Phosphate molecules.
  • Around 85% of the phosphorus found in phosphate is present in the bones. The remaining amount of it is phosphorus is present in the tissues of all body parts. In the body organs, kidneys help control the amount of phosphate in the blood.

Hope it helps!
