The correct answer is " Both the patients need re-vaccination"

As per the “Center for Disease Control and Prevention (CDC)” it is recommended that all adults of age 60 or above are at high risk of pneumococcal disease. As per their statistics every year thousands of adults die because of pneumococcal diseases.

CDC recommends that two series of vaccines against pneumococcal diseases is sufficient to protect adults against this disease:

• PCV13 (pneumococcal conjugate vaccine)

• PPSV23 (pneumococcal polysaccharide vaccine)

As per CDC all adults with age 65 or above but since the first patient of 66 years of age is diabetic, he must also get re-vaccinated along with the second patient of age 76 years.

The Venus flytrap is a carnivorous plant that traps insects in a plant structure. The plant structure closes when the small hairs on the inside of the structure are touched. The Venus flytrap can attract insects using a special type of plant communication. How can plants, like the Venus flytrap, communicate with other organisms?

Answers

Answer:

Venus flytrap communicate with other organisms by secreting a sugary substance (nectar) in its leaf glands.

Explanation:

The Venus flytrap is a carnivorous plant that traps insects in a plant structure that closes when the small hairs on the inside of the structure are touched.

The leaf of this plant contains a watery fluid secreted by glands on its open traps. Organisms like flies are attracted to the secreted nectar and perches on it; only for the hairs of the flytrap to get shut due to that touch and cell expansion triggered.

Answer:

Option (C) is correct, The Venus flytrap plant traps the insect by producing a sticky substance, while the spider attracts the insect by producing a special odor.

Explanation:

Venus flytrap special features that help it to attract insects

From these results it is concluded that Dionaea attracts insects on the basis of food smell mimicry because the scent released has strong similarity to the bouquet of fruits and plant flowers. Such a volatile blend is emitted to attract insects searching for food to visit the deadly capture organ of the Venus flytrap.
