Answer:

The mouth covered by chitin and intracellular granules of chitin (i.e. spindles) in nudibranchs

Explanation:

Nudibranchs are marine gastropod molluscs (Opisthobranchia, Mollusca). These organisms are carnivorous, so they feed on sponges, coral, anemones, hydroids, fish eggs, etc. On the other hand, cnidarians have specialized cells called cnidoblasts or cnidocytes that contain nematocysts made up of toxins that serve as a defense mechanism. Nematocysts are found in many species of Cnidarians such as, for example, in the tentacles of sea anemones. Interestingly, nudibranchs have developed some adaptations for feeding on these species. In the first place, nudibranchs have the mouth covered by a substance named chitin that allows them to chomp and swallow anemone tentacles. Second, they (nudibranchs) also have intracellular granules of chitin (i.e. spindles) in the digestive system that function as biological sandbags which maintain nematocyst toxins away from sensitive body parts.

Larger portions of the plant populations are susceptible to the same diseases.

The answer is option A

The hassle of small farmer livelihood is aggravated due to the truth that small farmers be afflicted by many manufacturing dangers like drought, flood, loss of ok use of inputs, poor extension leading to huge yield gaps, loss of confidence and adequate irrigation, crop failure and so forth.

The farmer's concerns are:

cope with weather exchange, soil erosion, and biodiversity loss.
satisfy customers' converting tastes and expectancies.
Meet the growing call for more meals of higher high-quality.
spend money on farm productivity.
undertake and learn new technology.
live resilient in opposition to worldwide financial elements.

Many farmers are worried about the decreasing genetic diversity of plants associated with generations of artificial selection and inbreeding. Why is limiting random sexual reproduction of food crops concerning?

a. Larger portions of the plant populations are susceptible to the same diseases.

b. Mutations during asexual reproduction decrease plant fitness.

c. Spores are not viable in an agricultural setting.
