Passage
People traveling to an island accidentally introduced mice into an ecosystem that previously had no mice. The population of mice quickly grew out of control. It started harming populations of native plants and birds. Scientists offered two solutions. One was to introduce cats to the island. The cats could hunt and eat the mice. The other suggestion was to introduce a disease that could infect the mice and reduce their population.
Answer:
Cat.
Explanation:
Introduction of cat can control the population of mice on the island more effectively as compared to the introduction of disease because the introduction of disease can cause damage to other population of that environment that adversely affected the ecosystem. Cat feeds on mice that act as a controlling agent in this ecosystem that will leads to decrease as well as controls the population from increasing in order to cause damage to the environment.

Bacteria that live in the digestive systems of cows help break down the plants that cows eat, providing nutrients to cows. The digestive systems of cows offer a safe environment in which the bacteria can live and reproduce. Which type of relationship exists between the bacteria and the cows?
A, commensalism
B, mutualism
C, parasitism
D, predation
The type of relationship that exists between the bacteria living in digestive system and the cows is that of mutualism.
What is mutualism ?Mutualism is an association or symbiotic interaction between two species where each species gets benefitted from one another.
Since the bacteria that live in the digestive systems of cows help break down the plants that cows eat, providing nutrients to cows and the digestive systems of cows offer a safe environment in which the bacteria can live and reproduce. This fulfills the condition of mutualism.

When modeling fisheries: (You may choose one or more answers)
A. Fixed quota models result in multiple maximum sustainable yield population levels
B. Fixed effort models result in an inability to harvest at maximum sustainable yield
C. Fixed quota models are risky because slight miscalculations can result in fish population extinction
D .Fixed effort harvesting reduces the risk of population extinction
Answer:
Option A, Fixed quota models are risky because slight miscalculations can result in fish population extinction
Explanation:
Some of the major drawbacks of modelling fishing are as follows –
a) The fixed quota model is very risky as a miniscule change in attributes can result into extinction of fish.
b) On the other hand fixed effort harvesting can decrease the risk of fish population extinction
Hence, option A is correct

Describe one property of water, and explain how the structure of water is responsible for this property. WILL MARK BRAINLIEST!!
Answer:
Water has cohesive and adhesive properties.
Water molecules have strong cohesive forces due to their ability to form hydrogen bonds with one another. Cohesive forces are responsible for surface tension, the tendency of a liquid's surface to resist rupture when placed under tension or stress.

A lack of CO2 in the flask would have caused reduced O2 production. If O2 , ATP, and NADPH are the by-products of the light-dependent phase of photosynthesis, how does a lack of CO2 cause reduced O2 production
Answer:
Carbondioxide is a reactant of photosynthesis.
Explanation:
Carbondioxide is a reactant of the process of photosynthesis and the product of photosynthesis is oxygen, if there is no or less carbondioxide the rate of photosynthesis decreases which leads to the lower production of oxygen. The rate of photosynthesis affected by the reactants available to it. If Carbondioxide is available in large amount more photosynthesis occurs that leads to more production of glucose as well as oxygen. So we can conclude that lack of Carbondioxide results in lower production of oxygen in the process of photosynthesis.

During a section of the cell cycle collectively called ______, the cell is not dividing, but protein synthesis, cell growth, DNA replication, and basic cell functions are occurring.
Answer:
INTERPHASE
Explanation:
The cell cycle refers to the series of event from DNA replication to actual division of a cell. Mitosis and meiosis are the two types of cell division, which is made up of two stages namely: interphase and the M-phase.
The interphase is also called resting stage because the cell is not undergoing any division. The interphase is further divided into G1, S and G2 phases. In these stages, the events that occurs include; protein synthesis, cell growth, DNA replication, and basic cell functions.
2) Which of the following are the smallest venous vessels?
A) large veins
B) venules
C) medium veins
D) capillaries
Venules are the smallest venous vessels (option B)
What are venous vessels?Venous vessels refer to the blood vessels for transporting blood from the tissues back, to the heart. They work in contrast to arteries, which carry oxygenated blood from the heart to the tissues.
Compared to arteries, venous vessels usually have dimensions and thinner walls. The reason, behind this is that they don't require pressure to transport blood. Additionally venous vessels possess valves that aid in preventing the flow of blood.
Base on the information above, we can infer that Venules are the smallest venous vessels (option B)
