Answer:
water molecules like to stick together (cohesion) and like to stick to the walls of the tubes of cellulose (adhesion
Explanation:
water moves from roots to leaves. ... Because water molecules like to stick together (cohesion) and like to stick to the walls of the tubes of cellulose (adhesion), they rise up the tubes all the way from the roots to the leaves.
Answer:
The correct option is d) UAG
Explanation:
Central dogma can be described as the process in which the transcription and translation occurs. The process by which mRNA is made from the DNA is called transcription and the process by which proteins are made by mRNA is called translation.
The first codon present on the DNA is TAG. The mRNA formed from this codon will be AUC. When this mRNA will travel from the nucleus to the cytoplam, the tRNA will bring the anticodons UAG for the first mRNA codon. Hence, the correct option is D.
Answer:
c) melatonin
Explanation:
Melatonin its a hormone formed by the pineal gland, which regulates an individual wake cycles and sleep. Jetlag alters the hormone function leading to an alteration with the body clock of the persom.
Jetlag is a sleep disorder common to those who travel swiftly over several time zones. It is not a permanent sleep disorder. Its due to the body's internal clock lacking sync with cues generated in a different time zone, Cues may be due to light exposure and how often the person eats.
A basic factor on ones internal clock is sunlight. It controls the regulation of melatonin which aid in synchronizing cells in the body.
Specific cells of the tissue at retina moves the light signals the thypothalamus.
At night, the hypothalamus signal to the pineal gland to produce melatonin. At daylight hours, the reverse is the case.
Answer:
TRUE
Explanation:
The green plants have green pigments present on their leaves, which are commonly known as chlorophyll. This chlorophyll pigments have the ability to absorb the necessary amount of sunlight, that is required to carry out the process of photosynthesis. Photosynthesis usually refers to the process where the green plants can synthesize their own food in the presence of sunlight, water (H₂O), and carbon dioxide (CO₂), and in return, it liberates food (glucose) and oxygen (O₂) that is essential for the survival of all living organisms.
The reaction that takes place during the time of photosynthesis is given below-
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
This process converts light energy into chemical energy, that is stored in the molecules of glucose.
Hence, the above statement is TRUE.
