O b. Simple cuboidal epithelium.

O c. Simple columnar epithelium.
Goblet cells' main job is to secrete mucin and produce a layer of protective mucus. Goblet cells may possibly have a role in the regulation of the immune system.Thus, option B is correct.
What epithelium is associated with goblet cells?Goblet cells' primary function is to secrete mucus in order to safeguard the mucous membranes that surround them. This is done by goblet cells secreting mucins, which are big glycoproteins made primarily of carbohydrates.
Goblet cells exhibit a distinctively polarized morphology regardless of fixation. Along with organelles like the Golgi, endoplasmic reticulum, and mitochondria, their nucleus is located at the base of the cell.
Mucus-filled secretory granules that are membrane-bound fill the remaining space in the cell.
Therefore, Most of the major airways are lined with pseudostrategized ciliated columnar epithelium that contains goblet cells. This tracheal pseudostratified epithelium is an illustration.

A population of rabbits lives in a grassy field that is lush and green in summer and covered in snow in winter. At the start of the summer, 75% of the population are white rabbits, and the remaining 25% of the population are brown rabbits. In rabbits, white (W) is dominant over brown (w). During the summer, the field where they live experiences a drought. The summer drought lasts for two years, through many generations of rabbits.
Which prediction BEST estimates the expected percent of white and brown rabbits in the population at the end of the drought?
Answer:
The rabbit population will consist of 35% white rabbits and 65% brown rabbits.
Explanation:
hope this helps!
The rabbit population will consist of 35% white rabbits and 65% brown rabbits.
What are the limiting factors of the rabbit population?Until a limiting factor, such as low reproduction, food scarcity, predation, disease, and/or weather conditions restrict populations, the population tends to grow.
Some density-dependent limiting factors are the spread of pathogens, competition for nesting locations, the destruction of habitat, increase in the population of predators. Several predators, including raptors and coyotes, use rabbits as food, but in urban and suburban areas, cats and dogs pose the biggest threat. Some abiotic limiting factors are drought, flood, earthquake, and all types of natural disasters.
Thus, the rabbit population will consist of 35% white rabbits and 65% brown rabbits.

the marine animals affected by the bloom do not eat algae. How could domoic acid have poisoned these organism?
Answer:
Domoic acid is a kainic acid-type neurotoxin that causes amnesic shellfish poisoning. It is produced by algae and accumulates in shellfish, sardines, and anchovies. When sea lions, otters, cetaceans, humans, and other predators eat contaminated animals, poisoning may result.
Explanation:
Blooms of algae affect ALL TROPHIC levels because domoic acid is a neurotoxin that accumulates in different species (e.g., shellfish, sardines, anchovies, etc) which are eaten by higher consumers (e.g., manatees and dolphins), thereby altering the equilibrium of the food chain.
A food chain refers to the transfer of matter and energy as food from different trophic levels in an ecosystem.
The food chain is sustained by organisms called producers (.e.g., algae in a marine ecosystem), which are found at the most basal level of the chain.
The primary consumers (e.g., marine invertebrates) are organisms localized at the second trophic level. These organisms (primary consumers) eat producers.
The secondary consumers are organisms found at the third trophic level, which eat primary consumers, and so successively to all major trophic groups.
Blooms of algae alter the whole food chain because domoic acid is a poison that accumulates in the body of the organisms at all trophic levels.
In consequence, marine consumers at higher trophic levels (e.g., manatees and dolphins) are also affected by blooms of algae.
In conclusion, blooms of algae affect ALL TROPHIC levels because domoic acid is a neurotoxin that accumulates in different species (e.g., shellfish, sardines, anchovies, etc) which are eaten by higher consumers (e.g., manatees and dolphins), thereby altering the equilibrium of the food chain.

Which of these events can lead to an increase in the population size of mice?
a. Some mice emigrate (leave) in search of food
b. Cats, owls, and snakes are added
c. More mice are born than die
d. A large number of mice die because of a forest fire
e. Cheese shortage
This means the birth rate would exceed the death rate, to make a positive growth rate in the population. So overall, the population will go up if more mice are born compared to those that die off.
Choices A, B, D and E all describe factors that would either kill mice or push them out of the habitat. Either way, these answer choices would have a decrease in population rather than increase. So we can eliminate these answer choices.

Despite the rampant depletion of trees in the natural forest in Ghana,it is still worth using wood as the main construction.Disscuss
Answer:
Hope this helps!
Explanation:
Forest resources support livelihood of people in jurisdictions in which forest is located. However, the forest size is gradually depleting continuously. The lack of information about the specific agents and forces of forest depletion is worrying. This is due to the inter-generational and intra-generational equity notions that affect mankind. As such, there is the need to maintain such resources on a non-declining value basis so as to maintain human welfare over time. Thus, the objective of this study is to empirically examine the determinants of forest depletion in Ghana over the 1970-2012 period in Ghana. This study employs multiple regression concepts to examine the effects of the determinants on forest depletion. The findings of the study indicate that gold extraction for export, population growth and logging increase the rate of forest depletion for the study period. More significantly, population growth reflected in settlement expansion, agriculture purposes, increased use of fuel wood, etc have greater effect on forest loss in Ghana. This suggests that, protection of the forest is necessary and sufficient condition for economic growth. As a result of these, both government and policy-makers need to safeguard the forest estate, by increasing afforestation schemes and also using part of the returns from gold exports to regenerate the forest.
