Answer:
25 years
Explanation:
Ossification is the process of bone tissue formation. Osteoblasts are responsible for the process of ossification. It begins when the fetus is three months old and goes on till 25 years of age. Upper limbs get ossified first, followed by lower limbs, sternum and vertebrae.
There are two types of ossification processes. When bone is directly developed using the primitive connective tissue (mesenchyme) it is called as intramembranous ossification, while in endochondral ossification cartilage is used as a precursor.
Answer:
Option (A).
Explanation:
Photosynthesis may be defined as the process in which the light energy has been converted to the chemical energy so that plants can obtain their food with the help of sunlight, carbon dioxide and water.
Photosynthesis is divided into light reaction and dark reaction. The light reaction of photosynthesis is linked together by the mechanism which is similar to the electron transport chain of mitochondria.
Thus, the correct answer is option (A).
Answer: The correct answer is D) Some energy in each trophic level is used for life processes.
Food chain represents the flow of energy through various living organisms (which lie at different trophic levels) in an ecosystem. The energy flows from one trophic level to the next and it is decreased with subsequent trophic levels.
As per the law of 10% energy transfer, only 10 % of the energy is transferred from one level to the next as the rest of the energy at every trophic level is utilized in various metabolic processes like respiration, digestion, excretion and also liberated as heat in the surrounding.
Due to this, the energy available at any trophic level is less than the previous trophic level.
D1, A2, B3, C4, and sicnce 5 and E are left i guess they mach up, but it dont think that water is a wast.. but the other one r right
Lunar Tides: the moon's gravitational pull on the Earth is strongest at this time, because it is closest, causing especially high and low tides.
Solar Tides: the sun's gravitational pull on the Earth is strongest at this time, causing especially high and low tides (although it's not as powerful as lunar tides).
Spring Tides: named for when the tides "spring" forward during New and Full Moon's, because of how strong/weak the moon's gravitational pull is.
Neap Tides: the tides are especially mediocre at this time, because the sun and moon are at a right angle and pulling in opposite directions.
Spring and Neap Tides occur twice every moon cycle, which lasts 28 days, so every two weeks.
