1. Why is DNA extracted from biological samples?
Well Basically if you and your family members are biological meaning related to each other it would make sense to take samples from them. And also in families there is always someone who inherit looks and the same blood like for example you may look like your dad and have the same blood type as him. ;) your welcome
Answer:
The ability to extract DNA is of primary importance to studying the genetic causes of disease and for the development of diagnostics and drugs.

which organism produce seeds during reproduction
Explanation:
The algae, ferns and mosses all produce spores while conducting the asexual mode of reproduction. The seeds are produced by flowering plants called as angiosperms. The seeds are the produced by sexual mode of reproduction. These are produced by the fusion of the male gamete that is pollen and female gamete that is ovum in within the flowers of angiosperms. The fusion helps in development of zygote which is the precursor of seeds.

How do the trachea, bronchi, bronchioles, and alveoli work together to process the oxygen that you inhale?
Answer:
The bronchial tubes divide into smaller air passages called bronchi, and then into bronchioles. The bronchioles end in tiny air sacs called alveoli, where oxygen is transferred from the inhaled air to the blood. After absorbing oxygen, the blood leaves the lungs and is carried to the heart.
Explanation:
Which type of mutation will affect the largest number of proteins produced by
an organism?
O A. Point mutation
B. Chromosomal mutation
C. Silent mutation
D. Missense mutation
SUBMIT
Answer:
chromosomal Mutation
Explanation: because the answer is B
The type of mutation will affect the largest number of proteins produced by an organism is Missense mutation. Thus, option D is correct.
What happens in sickle cell anemia?In sickle cell anemia, a change in the DNA nucleotide sequence is observed, where adenine is substituted by thymine, whose expression is the change in the sequence of amino acids in β-globin, with valine being incorporated instead of glutamic acid. This constitutes a mutation of the missense type.
Missense mutations are characterized by the substitution of one nucleotide by another in the DNA sequence —a point mutation— whose consequence is reflected in the transcription and substitution of one amino acid by another in a protein, whose structure or function will be altered.
The change from glutamic acid to valine in β-globin causes an altered hemoglobin, giving the abnormal erythrocytes observed in sickle cell disease.
Therefore, the type of mutation will affect the largest number of proteins produced by an organism is Missense mutation. Thus, option D is correct.

Compare and contrast the location and function of ribosomes in prokaryotic and eukaryotic cells.
Answer:
Explanation:
In eukaryotic cells, ribosomes are found in the cytosol of a cell, the mRNA , endoplasmic reticulum and also the matrix of the mitochondria. They are large molecules that catalyzes the synthesis of proteins, which is called translation. The ribosome choose tRNA and covalently links the amino acids into a polypeptide chain.
In prokaryotes, it can be found in cystosol and it help translate genetic code into protein.
El compuesto SeO y HgO es: * óxido ácido y óxido básico óxido ácido y óxido ácido óxido básico y óxido básico óxido básico y óxido ácido
Answer:
óxido ácido y óxido básico
Explanation:
Los óxidos son compuestos químicos formados por la combinación de un elemento químico con el oxígeno (O). Si el elemento que se combina es un metal, el óxido formado se denomina óxido básico. Por el contrario, si el elemento que se combina es un no metal, el óxido resultante es un óxido ácido.
Se (Selenio) es un elemento no metálico, por lo que su óxido (SeO) es un óxido ácido.
Hg (Mercurio) es un elemento metálico, por lo que su óxido (HgO) es un óxido básico.
