Heavy elements like gold (Au) and iron (Fe) are formed in what type of stars ?
Answer:
During a supernova, the star releases very large amounts of energy as well as neutrons, which allows elements heavier than iron, such as uranium and gold, to be produced. In the supernova explosion, all of these elements are expelled out into space.
Explanation:
the tree of life has been rearranged into three domains based on what evidence?
The tree of life has been rearranged into three domains based on DNA similarities. The linear order of nucleotides in DNA can be used to infer ancestry.
The three domains of the tree of life are Bacteria, Archaea and Eukarya.
Moreover, DNA is a double helix molecule composed of two long chains of nucleotides.
In DNA, there are four types of nucleotides, each containing one different nitrogenous base: Adenine, Guanine, Cytosine and Thymine.
The level of conservation observed in the linear order of nucleotides in the DNA molecule can be used to recognize homology caused by ancestry (i.e., homology in the nucleotide sequence) between different types of organisms.

If you know that a DNA double helix consists of 20 % adenine, what percentage of the DNA double helix is guanine (G)
Answer:
80%
Explanation:
As per rules the percentage of adenine is equal to thymine and C is equal to G. If A is 20 then the value of T is 20 too and along with that C and G are equal. The value of G is 30%.
What type of bonding is present between adenine and thymine ?Hydrogen bonding is present between the bases where the two hydrogen bonds are present in between A and T. C and G are binding together by three hydrogen bonds.
Adenine is 20% that means thymine is equal to 20% as well where the remaining percentage out from 100 % is 60% where the value if cytosine and guanine are equal and the percentage they have is 30% and 30% that is guanine is 30%.
DNA always in the structure has adenine residues equal to thymine residues and cytosine residues equal to guanine residues thus the value of their composition in the structure can be predicted by this.

Which term best describes receptors that detect body and limb movements, skeletal muscle contraction and stretch, and joint capsule structure?
Proprioceptors are known as receptors which help to detect body and limb
movements, skeletal muscle contraction etc.
These receptors are present in the subcutaneous tissue of the skin which is
the organ responsible for feeling and touch sensations. Proprioceptors help
to detect body and limb movements, skeletal muscle contraction and stretch, and joint capsule structure
In pregnant women, proprioceptors help to relay information to the brain
when a part of the body is moving. This is why it's the right choice.

what three conditions are necessary for natural selection to occur
For the natural selection to occur, the basic rule is that species that fit the best are selected by nature to exist in the nature. The 3 conditions that are required by nature for natural selection to occur are :
1. Struggle for existence
2. Variation
3. Inheritance
What is natural selection ?The offspring that is fit for the nature following the adaptation to the variation and inheritance crossing the struggle for existence to occur in nature tends to be selected by the nature to exist and produce more offspring.
The organisms that are adapted to the nature following the mutations and variations that are required for the better adaptations live more than the species which has lesser adaptation. These species produce more offspring.
