Curate a collection of diagrams and photographs that illustrate the structure and makeup of DNA, as well as its location in the cell. Then, research a method of using isopropyl alcohol and a liquid detergent in order to extract and observe your own DNA. Photograph your results and add the labeled photographs to your digital DNA gallery.
The isopropyl method of DNA extraction is a lab based technique hence the pictures and results cannot be provided here. The DNA structure consists of a sugar phosphate backbone and a nucleotide base.
The double helix shape of DNA, a two-stranded molecule that seems to be twisted, is what differentiates it from other molecules. Each of the two strands is made up of a phosphate molecule and a lengthy series of nucleotides. a five-carbon sugar molecule known as deoxyribose. a region rich in nitrogen.The majority of DNA is found in the cell nucleus (where it is known as nuclear DNA), but there is also a tiny quantity of DNA in the mitochondria (where it is called mitochondrial DNA or mtDNA).Cellular organelles called mitochondria transform the energy from food into a form that cells can utilize.

what are the effects of anaemia
Answer:
Irregular heartbeat. Heart Failure. Fatal. The body does not get "oxygen-rich" blood. May feel tired or weak. Shortness of breath, dizziness, headaches. Blood loss, lack of red blood cell production, and high rates of red blood cell destruction
Explanation:
When you're anemic your heart pumps more blood to make up for the lack of oxygen in the blood. This can lead to an enlarged heart or heart failure.

For this question, you have to draw a punnet square
Explanation:
A B
i Ai Bi
i Ai Bi
For AB blood type, one parent can give either an A or a B. For the other parent because they are 0 blood type that means that they are negative for both factors.
For someone who would be A, they could be AA or Ai( but that is irrelevant for this question)
The i reffers to no antigen markers, it is kind of just a placeholder. You could have written (O,O) instead
is water losing through transpiration harmful or benefical for plant
Answer:
Beneficial. Read below
Explanation:
Water naturally does evaporate from the leaves. When it does, it makes a sort of suction in the 'pipes' of the plant. Think of it like when you drink from a cup with a straw. You take juice out from the straw by sucking it but that makes the juice still in the cup go up to replace that lost juice. This is how plants absorb water from the roots. If transpiration didn't happen, plants wouldn't be able to absorb water apart from osmosis but that would be too slow.
Look at least two molecules diagrams and think about the features of compounds.
Answer:
---> are isomers of each other
---> have same molecular formula
---> are both hydrocarbons
---> have same number of each kind of atom
Explanation:
Isomers with the same molecular formula. The molecular formula gives a list of the type and quantity of each element in a molecule.
In other words, they are two different molecules with the same type and amount of atoms. The difference is that their structures are different. That being said, the structural formula of the molecules would not be the same. Hydrocarbons are molecules that only consist of carbon (C) and hydrogen (H) atoms.

Punnett squares are used to get the genotypic and phenotypic frequencies among the progeny produced from a cross. Punnett squares and answers below.
What is a punnett square?The Punnett square is a graphic representation that shows the different types of gamete combinations according to the alleles involved in a cross.
Punnett square shows the probabilities of getting offspring with different genotypes and their consequent phenotypes.
In the exposed example,
Diallelic genes that codes for colorY = yellow ⇒ dominant alleley = blue ⇒ recessive alleleWe will assume complete dominance, meaning that with at least one dominant allele in the genotype, the expressed color is yellow.
1)

An atom charged -3 has atomic number 23 and atomic mass 32 what is the number of electrons of this atom
An atom charged -3 has the atomic number 23 and an atomic mass of 32, the number of electrons of this atom are 20.
What is an Atomic number?An atomic number may be defined as the number of a chemical element in the periodic table, in which the elements are positioned in order of expanding the number of protons in the epicenter known as the nucleus.
In this question, the number of electrons is 20, because the number of electrons in an atom is always equal to the atomic number of that atom, which is 23 here.
But, an atom charged -3, so, 23-3 = 20. If an atom is charged negative, the number of electrons is determined by subtracting it with an atomic number, while if it is charged positive, the number of electrons is determined by adding it with an atomic number.
Therefore, it is well described above.

The essential roles including barrier protection, fluid balance, the release of particulate, initiation of immune responses, mucus and surfactant exhibit, and repair following injury.
What is respiration?Inhalation:
On inhalation, the pressure in the alveoli is high, hence the Oxygen diffuses to the nearby blood through the membrane.
Exhalation:
It is the process in which a person releases the air collected in the lung. During exhalation, the pressure in the alveoli is low, hence the carbon dioxide present in the blood is diffused out into the alveoli.
Therefore, the expandable structure of alveoli helps the respiratory system to follow its function.
