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

Which of the following is the correct flow of energy?
a. The crab gets energy from eating plants.
b. The heron gets energy from eating plants.
c. The crab gets energy from eating the heron.
d. The heron gets energy from eating the crab.
Answer:
d. The heron gets energy from eating the crab.
Explanation:
The heron gets energy from eating the crab. The heron primary feeds on small fish but also on shrimp, crabs, small mammals, amphibians, small birds, rodents, and insects when the fish are not available. After shedding of crab's shell, crabs are prey for fish and birds, and eaten by fish and birds like heron whereas, crabs feed primarily on algae, as well as other food, including molluscs, worms, other crustaceans, fungi, bacteria, and detritus.
why is the cell cycle often represented as a circle
Explanation:
The cell cycle is a cycle, rather than a linear pathway, because at the end of each go-round, the two daughter cells can start the exact same process over again from the beginning.

he majority of animals are invertebrates. This means that they have this characteristic.
lack a backbone
have a backbone
lack cell walls
have cell walls
Answer:
Lack a backbone
Explanation:
Invertebrates are animals that no not have a backbone. 'Vertebrae' is the scientific term for a spine. The prefix 'in' implies a lack of something, in this case a backbone.
So, an invertebrate is an animal that does not have a backbone.
Good luck ^^
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.

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.

Which taxa would include more species: Order or Phylum? *
Answer:
Phylum
Explanation:
Think about the taxonomy pyramid as a filter: the filter with the most holes is the Domain, which means animals, or coffee beans can go through easily. But as you move down the triangle, the filter becomes finer, so we are picking through the coffee beans for specific ones only.
Phylum is more "course" than Order, in which the people are more selective about the "coffee beans".
Below is an image of the triangle in case.

Nitrogen makes up about 78% of the air. Most living things cannot take nitrogen out of the air and use it to make the DNA, ATP, or proteins they need to live. All life on earth depends on few species of _____ that can take nitrogen from the air and make these things.
Answer: The options are not given, here are the options gotten from another website.
Fungi
Algae
Bacteria
Plants.
The correct answer is bacteria
Explanation:
This is because there are some bacteria that can convert atmospheric nitrogen into ammonia or nitrates which is absorbed by plants and stored in plants as source of protein, DNA for other organisms after consumption. Some bacteria reside in the root nodules of leguminous plants that convert atmospheric nitrogen to ammonia or nitrates. They are called nitrogen fixing bacteria which include nitrosomonas, Azotobacter. Nitryfing bacteria convert ammonia to nitrites or nitrates.
In 1953 the collared dove had never been in the United Kingdom. Why does the growth of the collared dove flatten out in 1971
Answer:
May be climate change, introduction of invasive species and unavailability of food etc.
Explanation:
The growth of the collared dove flatten out in 1971 because of many reasons such as climate change, introduction of invasive species and unavailability of food etc. Climate change is the main problem that affect the growth of every organisms across the globe. The changing of temperature of the world causes migration in the collard dove to other suitable regions which leads to decrease in the population of the dove. Invasive species also decreases the population through feeding on them or competition for resources.

After 29.5 days
Explanation:
Complete question
If the moon started its orbit from a spot exactly between Earth and the sun, then after how much time it would return to almost the same spot ?
Solution
New moon occurs once in 30 days. Hence there is a gap of 30 days between two new moons. To be specific moon phases repeat after every 29.5 days. However, as per the Gregorian calendar there can be two new moon in one month with a gap of 15 days only between two new moons.
