Question
What are some effects of the tiny beads called microplastics that are a large component of ocean garbage patches? A) They absorb carbon dioxide.
B) They are often consumed by animals, making animals sick.
C) They clog pipes and drains.
D) They create gyres.
Solution 1
The correct answer is B.
Microplastics are very small pieces of plastic (less than 5 mm in diameter) which can be found in the environment. Microplastics mostly come from larger pieces of plastic which degrade and turn into these tiny parts of plastic.
It has been shown that microplastics are a very important problem of the marine environment, mainly because they are ingested by marine organisms. Due to their small size, they can be embedded in the tissues of many organisms. This can cause serious health problems, from physical harm to starvation caused by a false feeling of satiety.

Question
Antlions can experience competition when
Solution 1
Antlion pits are often spatially aggregated even though there are potential negative effects associated with the aggregation (e.g., heightened competition and predation risk). This study investigated the possibility that a strategy leading to aggregation can be an evolutionarily stable strategy (ESS). In particular, the strategy considered was ‘decreasing relocation tendency when there are neighbors’. An individual based model showed that the strategy can be the unique ESS when the spatial distribution of prey is not completely random and antlions can learn it from their past foraging experiences. A laboratory experiment was conducted to examine the effects of the presence of neighbors and foraging success on the relocation behavior of antlion larvae. Antlions reduced their relocation tendency with respect to these factors, consistent with the predicted ESS. The results suggest that pit aggregations are formed because antlions reduce their relocation tendency when neighbors exist, and this strategy is an ESS.

Question
The proteins necessary for life are assembled by the ribosomes of cells. These proteins include enzymes, which are proteins that can reduce the activation energy needed for certain chemical reactions. One very important role that enzymes play in eukaryotic cells is to allow energy production to occur by catalyzing the chemical reactions involved in cellular respiration. Suppose an enzyme that is involved in cellular respiration is assembled by a ribosome. Where will this enzyme need to be transported in order to perform its function?
A. to the nucleus B. to a chloroplast C. to a vacuole D. to a mitochondrion
Solution 1
The correct answer is D. to a mitochondrion.
Cellular respiration is a four-stage process where a glucose molecule is gradually broken down into CO2 and H2O and some ATP is produced. The steps are:
1: Glycolysis- It occurs in the cytosol, glucose is Broken down into two molecules of pyruvate, ATP is made, and NAD+ is converted to NADH.
2. Transition Reaction-Pyruvate is shuttled into the mitochondria and converted to Acetyl CoA for further break down pyruvate oxidation).
3. The Krebs Cycle, or Citric Acid Cycle- Occurs at the mitochondrial matrix. The acetyl CoA goes through a cycle of reactions and as a result, ATP, NADH and FADH2 are produced, CO2 is released.
4.The Electron Transport Chain-Occursin the inner membrane of mitochondria, The NADH and FADH2 which are made in other steps deposit their electrons in the electron transport chain, (becoming NAD and FAD). As electrons move down the chain, energy is released and used to pump H+ out of the matrix, forming a gradient for further ATP production (oxidative phosphorilation).

Question
Which property of water helps support life in this harsh Arctic environment?
Solution 1
The icy waters of the Arctic and Antarctic Oceans sustenance a great amount of marine life. For millions of years, life has remained unchanged, making it possible for these animals to adapt themselves to these particular patterns of existence. Due to water's cohesiveness, water's polarity enticed to other water molecules. The hydrogen bonds in water grasp other water molecules unruffled. Also the Cohesion or known as water's attraction to other water molecules is one of the major properties of water.

Question
When habitats are destroyed, specialized species are more likely than generalized species to _____. adapt to change
migrate to new habitats
move into a new niche
become extinct
Solution 1
Answer: become extinct
A generalist species is able to thrive in a wide variety of climate and environmental conditions and have varied diets. When their habitats are destroyed, they can easily adapt to change, migrate or move into a new niche.
A specialist species can thrive only in a narrow range of climate and environmental conditions and has a limited diet. When this environment or habitat is destroyed, they are most likely to become extinct than the generalist species.

Question
Which of these is a disadvantage of using renewable resources, such as wind energy and sunlight, instead of using renewable resources? A) Renewable resources are widely available.
B) Renewable resources can be impacted by weather.
C) Renewable resources produce less waste materials.
D) Renewable resources must be imported from other countries.
Solution 1
Renewable resources can be impacted by weather because it is present in open environment.
Factors affecting renewable energy
Renewable energy technologies are highly dependent on climatic factors such as sunlight, wind speed and water availability. Due to direct interaction with environment, the renewable resources can be affected by weather conditions so we can conclude that renewable resources can be impacted by weather because it is present in open environment.

Solution 2
Answer:
The Correct Answer is B.
Explanation:
- Renewable energy also depends on weather for its sources of power.
- Hydro generators required rain to fill dams to supply flowing water.
- It is difficult to produce that much electricity as we can produce by the traditional methods by using fossil fuels.
- Wind turbines need wind and solar energy need a clear sky and sunny day to collect heat and produce electricity.
