Cytokines

Which of the following is not responsible for increase carbon dioxide emissions?

Decomposing food waste in landfills

True or False: A decrease of gene flow will inhibit speciation.

False

True or False: Life on Earth only appeared after continental drift ended and the continents took their final positions.

False

True or False: One consequence of cytokines being released from infected cells of the lungs is decrease moisture on the walls of the alveoli that then prohibits oxygen from crossing through the membrane.

False

True or False: The heritable traits acted on by evolution can be from either somatic of germline genomes.

False

True or False: Weather and Climate refer to the same thing and the terms can be used interchangeably.

False

A high-risk factor for diabetes in humans is hypothesized to have come from Neanderthals as humans and Neanderthal interbred in Europe/the Middle East. This is an example of?

Gene flow

Reproductive barriers result in a decrease of?

Gene flow

Over-hunting of the elephant seal population in the 1890s nearly caused an extinction of the species. The species has now rebounded and has much less genetic diversity that it originally did. This is an example of?

Genetic Drift

Which of the following are not inputs for photosynthesis?

Glucose and Oxygen

Homosapiens and Homohabilus both have an upright bipedal (walking on 2 legs) posture that they have inherited from their last common ancestor. Thus, this characteristic is considered a(n) ___ trait?

Homologous

If we were discussing evolution, which of the following would not be included in the discussion?

Individual

What is the role of the Calvin Cycle in Photosynthesis?

It contributes to building glucose

If we were discussing how frequent the high-risk diabetes allele is in a particular population of humans, we would be discussing?

Microevolution

My neighbor uses solar energy to heat water for his pool. This is an example of?

Mitigation

Scientists have determined that T. rex was more closely related to chicken and ostrich compared to alligators based on the sequence of a short section of a collagen protein. This is an example of ___ evidence?

Molecular Biology

I applied a fungicide to my sick plants and they seemed to be getting better for a while. Then, the fungus just overtook the plants and the fungicide no longer worked to kill the fungus. This is an example of?

Natural Selection

The 3 main types of greenhouse gasses of concern that we discussed in class are carbon dioxide, methane, and?

Nitrous Oxide

Behavioral isolation most often affects which mechanism of microevolution?

Non-random mating

Ribosomes & An Envelope

If there were mutations to the S protein of SARS-CoV 2, then one would expect there to be changes in?

The ability of the virus to bind to and infect the host cell

An increase in spillover events in the last several decades has been attributed in part to large part to?

The meat industry

True or False: Geographical isolation leads to allopathic speciation and is the most common cause of speciation.

True

True or False: In order for a trait to be acted on by evolution, the trait must be a heritable trait.

True

True or False: One drawback to solar radiation management as a solution to global warning is that it does not decrease green house gas emissions.

True
