They are said to be “denser” than air. what happens is that light slows down when it passes from the less dense air into the denser glass of water. this slowing down the ray of light also causes the ray of light to change directions. it is the change in the speed of the light that causes refraction.
Answer:
They have no vascular system.
Explanation:
Vascular system contains an important feature they have series of tubes which helps to transport nutrients, and water over a distance in plants. The vascular system of phloem, and xylem allows trees (such as redwood) to grow a hundred feet tall.
Mosses do not have vascular system. Without the vascular system liverworts, and mosses are not able to grow large. Mosses are rarely one inch in height. Mosses are small flowerless waxy plants with no stem, and leaves.
Answer:
* Infectious disease management depends on precise portrayal of disease progression so transmission can be forestalled. Gradually progressing infectious diseases can be hard to characterize because of a latency period between the time an individual is infected and when they show clinical signs of disease.
* Defining directions through sickness states from infection to clinical illness can assist researchers with creating control programs dependent on focusing on individual infection state, possibly decreasing both progression and creating misfortunes because of the illness.
Explanation:
Gradually progressing infectious diseases are hard to characterize in light of the fact that they are frequently connected with an inactivity period between the time an individual is infected and when they give clinical indications or side effects of illness.
To successfully control infectious diseases, it is paramount to see how the disease progresses.
The Carbon dioxide in the atmosphere is absorbed by green plants (producers) to make food in photosynthesis.
Answer:
The correct option is B. The offspring will inherit neither the genotype nor the phenotype change.
Explanation:
Any changes which occur in the DNA sequence of a person are termed as mutations.
Mutations will only be transferred to offsprings if the mutated gene or sequence gets incorporated into the genome of the mutated person.
In the above scenario, the mutation is just changing the person's phenotype and it has not been incorporated in the genotype of the affected person. Hence, the offsprings will not inherit the mutation, nether in their genotype nor the phenotype.
