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.Ubiquitous use of catalysts by living systems
B.Near universality of the genetic code
C.Structure of the nucleus
D.The flow of genetic information from DNA to RNA to protein
E. The directionality of protein synthesis
Answer:d
Explanation:
The organism is made of genetic material that it inherits from the parent cell. The universality of the genetic code provides evidence of the common ancestry of all life. Thus, option B is correct.
What is a genetic code?A genetic code is a triplet of nucleotides that are also defined as codons that characterizes a specific amino acid produced through the process of translation. It consists of the DNA or RNA as the base that forms the codons.
The codons have been unambiguous for a type of amino acid it codes, universal for all living organisms irrespective of the kingdom, and redundant. They are crucial evidence that supports the common originality theory of organisms.
Therefore, option B. the universality of the genetic code is evidence that supports the theory of common ancestry.

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.

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.

Dr. Nachman and his colleagues collected rock pocket mice across 35 kilometers of the Arizona Sonoran Desert, which included both dark, rocky lava outcrops and light, rocky, granite areas. They recorded substrate color, and coat-color frequencies for each location. Each site was separated from any of the others by at least eight kilometers. The researchers trapped a total of 275 mice. Their data are summarized below (numbers have been slightly modified for the purposes of this worksheet).
(numbers have been slightly modified for the purposes of this worksheet).
Field Data Summary
Collecting Site Substrate Color Number of Mice Phenotype
Light Dark
1 Dark 22 3 19
2 Light 80 74 6
3 Light 22 19 3
4 Dark 28 3 25
5 Light 58 25 33
6 Dark 65 9 56
1. Calculate the overall frequencies of light-colored mice and dark-colored mice caught on light-colored substrates.
2. Calculate the overall frequencies of light-colored mice and dark-colored mice caught on dark-colored substrates.
3.Using the Hardy-Weinberg equation and data from the table above, determine the frequency of the three genotypes on the light, rocky, granite substrate.
4. Using the Hardy-Weinberg equation and data from the table above, determine the frequency of the three genotypes on the dark, rocky lava substrate.
5. Which fur color seems to have the greatest overall selective advantage?
6.What environmental change gave a selective advantage for one coat color over another?
7. In a separate study, 76 rock pocket mice were collected from four different, widely separated areas of dark lava rock. One collecting site was in Arizona. The other three were in New Mexico. Dr. Nachman and colleagues observed no significant differences in the color of the rocks in the four locations sampled. However, the dark-colored mice from the three New Mexico locations were slightly darker than the dark-colored mice from the Arizona population. The entire Mc1r gene was sequenced in all 76 of the mice collected. The mutations responsible for the dark fur color in the Arizona mice were absent from the three different populations of New Mexico mice. No Mc1r mutations were associated with dark fur color in the New Mexico populations. These findings suggest that adaptive dark coloration has occurred at least twice in the rock pocket mouse and that these similar phenotypic changes have different genetic bases. How does this study support the concept that natural selection is not random?
8. To determine if the rock pocket mouse population is evolving, explain why it is necessary to collect fur color frequency data over a period of many years.
Answer:
1)
frequencies of light-colored mice ≅ 0.74frequencies of dark-colored mice ≅ 0.262)
frequencies of light-colored mice ≅ 0.13frequencies of dark-colored mice ≅ 0.873)
q² = 0.74p² = 0.02 2pq = 0.244)
q² = 0.13p² = 0.42pq = 0.465)
The dark-colored fur seems to have the greatest overall selective advantage
6)
Dark lava, that changed the color of the substrate, from light to dark.
7)
Because to produce dark color, animals from the different regions suffered different mutations that drove them to have almost the same dark fur color. All of the animals are inhabiting dark substrate, which means that this environmental condition is favoring the same phenotype.
8)
To see if the mice population is evolving, you need to take a sample of animals per year, through many years, and analyze if it is changing or not. If the population is evolving, you will notice a change in the allelic and genotypic frequencies over the years, favoring one genotype or the other. If the population is not evolving, the frequencies will keep equal through the years, it will not change.
