The micropyle is a hole in the seed coat, it is literally nothing. Hence it is not made of cells and has no chromosomes.

The aleurone layer is the outermost layer of the endosperm. Therefore it is also triploid and same as the ploidy of endosperm.
There are many types of level sensors you can use to measure the water level in a tank such as submersible level sensor, ultrasonic level sensor, float level sensor. If you are searching for a level sensor you visit our website iconprocon[dot]com
This is because energy is lost at each trophic level (from all the activity done by that level, e.g., running, climbing, fighting) . The energy available to the next trophic level is about 10% of the energy of the previous trophic level.
Magikarp evolve at level 20.

A zygote is a diploid

During the first stage of the life stage the butterfly has a micropyle. The micropyle is a funnel shaped opening located at the bottom of the egg.
The ploidy level of a seed coat is typically diploid, meaning it contains two sets of chromosomes. This allows the seed coat to develop and protect the seed embryo inside during germination and growth.
Generally, a somatic cell in a human body has 46 chromosomes, which are two complete sets of 23 chromosome pairs. Because they have two sets, these cells have a ploidy level of diploid.
Endosperm of gymnosperm is haploid(ploidy n), develop from megaspore (n) before fertilization. ploidy of endosperm in angiosperm is 3n(central cell fused with one male gamete i.e 2n+n).
Yes, all seeds have a hilum and a micropyle. The hilum is the scar on the seed where it was attached to the plant, and the micropyle is the small opening in the seed coat through which the pollen tube entered during fertilization.
The micropyle opening allows the pollen tube to enter the ovule for fertilization. It absorbs water for germination. It provides for the diffusion of respiratory gases.
