Haldane, a Soviet scientist, proposed in 1929 that a combination of carbon dioxide, water, and ammonia, when exposed to ultraviolet light, can form a variety of organic molecules. The conditions modeled by Haldane's experiment simulated the oceans of early Earth. Which hypothesis of the origin of life on primitive Earth is described by Haldane's experiment? A) panspermia hypothesis B) abiogenesis hypothesis C) primordial soup hypothesis D) hydrothermal vent hypothesis
Answer:
C) Primordial Soup
Explanation:
The idea of the primordial soup was originally proposed by Alexander Oparin and John Haldane as a possible explanation for the creation of life on our planet. The theory states that if energy is added to the gases that made up Earth's early atmosphere, the building blocks of life would be created.

Which contributes to the greenhouse effect?
The greenhouse effect is when the Sun's light is trapped into the lower atmosphere, heating up the planet. Carbon dioxide, or co2 makes up the majority of greenhouse gas emissions. Smaller amounts of methane(ch4), and nitrous oxide(n20) are also emitted. These gases are mainly emitted through the continuous use of fossil fuels such as coal, oil, and natural gas.

In general, the probability of flooding decreases when there is an increase in the amount of
1) infiltration
2) Snow melt
3) runoff
4) precipitation
Flooding is a natural disaster that is caused due to overflowing water. The possibility of flooding decreases when there is an increase in infiltration. Thus, option 1 is correct.
What is infiltration?Infiltration is the process of Hydrology where the water on the upper layers or the ground moves and sweeps inside the soil through permeability or filtration. The soil shows the property of infiltration allowing the water to move through the different soil profiles.
The greater the infiltration property of soil the greater it will absorb the groundwater into it. This will decrease the case of flooding as no water will get deposited on the ground. It will raise the water level of the table and decreases the water pooling at the surface.
Therefore, option 1. an increase in infiltration, decreases the flooding.

Genes located close together on the same chromosomes are referred to as ________ genes and generally ________.
Given what we know, we can confirm that Genes located close together on the same chromosomes are referred to as linked genes.
What are linked genes?Linked genes have to do with inheritance. Linked genes are those that are very likely to be inherited together, though not a guarantee, due to their position in the chromosome being very close to one another. This also means that these genes do not separate during meiosis.
Therefore, we can confirm that Genes located close together on the same chromosomes are referred to as linked genes and do not separate during meiosis.
