The eye can focus on an object situated at different distances by changing the tension in its ciliary muscles. When muscles are relaxed, the eye lens becomes thin and its focal length increases and distant object can be seen clearly. While looking at nearby objects the ciliary muscles contract, the lens becomes thick, short and its focal length decreases.

Filtration

Meghna Thapar 5 years, 3 months ago

A nephron is the basic structural and functional unit of the kidneys that regulates water and soluble substances in the blood by filtering the blood, reabsorbing what is needed, and excreting the rest as urine. Its function is vital for homeostasis of blood volume, blood pressure, and plasma osmolarity. The nephron uses four mechanisms to convert blood into urine: filtration, reabsorption, secretion, and excretion. These apply to numerous substances.

Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Pollination is when pollen grains from an anther, the male portion of a flower, are transferred to a female part in the flower, known as the stigma. ... There are two types of pollination, called self-pollination and cross-pollination. Pollinating agents are animals such as insects, birds, and bats; water; wind; and even plants themselves, when self-pollination occurs within a closed flower.

Swathi Gajavelli 5 years, 3 months ago

In plants, new offsprings are produced by asexual reproduction. Stamen is the male reproductive part of the plant and pistil is the female reproductive part of the plant. Pistil is made up of three parts - stigma, style and ovary. Stamen contains pollen grains (male germ cells), which are yellow in colour and ovary contains ovule and each ovule has an egg cell (female germ cell). Pollens are transferred to stigma either by air, water or insects. Then, they reach to ovary through style. In ovary, fusion of pollens and egg cell take place and zygote is produced.
