Answer:
Primitive Earth (Before life) contained no or very little Oxygen (element#8)
According to scientific theory:
Earth had no oxygen to begin with. It had a lot of carbon dioxide, though. Somehow (We still do not know how they started growing) single-celled Carbon Dioxide-breathing bacteria slowly, over thousands to millions of years, turned most carbon dioxide into oxygen, supporting new types of life.

Explain the following statement: "Selection occurs within
generations; evolution occurs between generations."
Answer: Selection occurs within generations; evolution occurs between generations. All four of Darwin's postulates are true for the medium ground finch population on Daphne Major. Darwin's theory therefore predicts a change in the composition of the population from one generation to the next. In biology, evolution is the change in the inherited traits of a population from generation to generation. ... Natural selection is a process that causes heritable traits that are helpful for survival and reproduction to become more common, and harmful traits to become more rare.
Explanation:
Natural selection is the process by which heritable qualities that help with survival and reproduction become more common while harmful traits become rare
Evolution is defined as a change in the heritable traits of biological populations. These traits are the manifestations of genes that are passed down from one generation to the next during reproduction.
Selection occurs inside generations, while evolution occurs between generations. All four of Darwin's postulates are met by the medium ground finch population on Daphne Major. Darwin's theory anticipates a shift in population composition from generation to generation as a result. In biology, evolution is the change in the inherited traits of a population from generation to generation. Natural selection is the process by which heritable qualities that help with survival and reproduction become more common while harmful traits become rare.

Putrescine and cadaverine are short aliphatic diamine compounds produced during the breakdown of amino acids in both living and dead organisms. What tests, including solubility, would you run in order to confirm their structure
Answer:
In order to confirm the structure of Aliphatic Diamine Compounds, you'd need to run a set of tests. They are:
A. Preliminary or Initial Tests:
I. Tests for Physical Traits: this helps to determine or establish the physical traits of the substance. Characteristics such as State of Matter (e.g. solid, liquid) color, and odor.
II. Ignition test. This involves the application of heat on a minuscule amount of the compound or substance using a metal spatula. This helps to prove whether the compound is aliphatic or aromatic. An aliphatic compound such as methylated spirit is aliphatic because it produces a luminous flame. Vegetable Oil on the other hand is aromatic because it produces a sooty flame.
B. Physical Constants
This test aims to establish the boiling and melting points of such a substance.
C. Analysis for elements present
D. Solubility tests
Explanation
Amine compounds are easily distinguishable by their odors. Amine odors have a somewhat fishy almost putrid quality.
When they are at room temperature, they are present as gases and can easily evaporate in their liquid state.
Their relative densities are lower than that of water. with the exception of aromatic amines.

how do autotrophs breakdown energy that it created through photosynthesis
Answer:
Some types of bacteria are autotrophs. Most autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose. Glucose is a type of sugar.

Explanation:
Leigh's disease is a mitochondrially inherited disease with symptoms that include seizures, fatigue, impaired reflexes, breathing problems, and ataxia. The pedigree shows the presence of Leigh's disease in three generations. Individual 4 had two daughters and one son, and individual 6 had one daughter and two sons. Which of the individuals indicated are affected by Leigh's disease
About the question:
You will find the pedigree in the attached files
Answer:
individual 4 → Affected woman → Black circleindividual 5 → Affected woman or man → Black circle or squareindividual 7 → Healthy woman → Empty circleindividual 10 → Affected boy → Black SquareExplanation:
Mitochondrial inheritance is the transmission of a disease or a trait from the maternal line.
Most of the DNI is in the nucleus, but there is also DNI in mitochondria. Sperm cells hardly transfer mitochondrial genes to the progeny, so mitochondrial DNI is mostly inherited from the maternal side. If there exists any mutation in this mitochondrial DNI, the whole progeny of the mutated woman will be affected, as they will get the mother genotype carrying the mutation. On the contrary, if an affected man is carrying a mutation in mitochondrial DNI, non of their descendants will get the disease.
Before answering the question, let us remember the pedigree symbols.
Squares represent Males/Men Circles represent Females/WomenEmpty symbols represent healthy/non-affected individualsSolid black symbols represent sick/affected individualsIn the exposed pedigree, we can see that the mother is affected by the disease (individual number 2), so all her children are also affected (individuals 4, 5, and 6) because the disease is mitochondrially inherited.
Individual 3 is a healthy man, so individual 4 must be an affected woman (Black circle). As she is the one affected, then all her children will also be affected. This couple had one boy and two girls. Individuals 8 and 9 are girls (circle), so individual 10 must be the affected boy (black square).
On the other hand, individual 6 is an affected man (black square), son of individuals 1 and 2. This man couples with a woman, and they have all healthy children. So this woman (individual 7) must be healthy. Even though the man is affected, all their children are not because their mother (7) is not. Remember that sperm cells do not transmit the mitochondrial genes to the progeny.
And finally, individual number 5 might be either a man or a woman. In any case, this person is also affected by Leigh's disease.
