Answer:
The first astronauts to land on the moon observed the existence of thin layers of dust hovering above the lunar surface. Like there is no wind on the moon, it was understood that this phenomenon was linked to the photoelectric effect caused by sunlight: electrons are extracted from the
grain of dust from lunar soil when receiving energy electromagnetic radiation from the sun and, thus the grains become positively
loaded.
The same process also starts electrons of the lunar surface, contributing to the positive charge on the illuminated side of the Thus, the electric field generated by the surface of the moon makes the charged grains of sand suffer electrical force upward by balancing your weight
Explanation:
Dust can be formed by small particles, smaller than 500 micrometers, but the nature can be so different from one place to another.
Answer: High Frequency waves by method of compression bone conduction
Explanation: in this, vibration of the bones of the skull and sometimes, arguably soft tissues leads to the production of sounds. The outer and middle ear is bypassed in this method of sound production. Sound reaches the inner ear directly and its a process largely involved in designing hearing aids.
Answer:
If their offspring can reproduce
Answer:
9- C
cellulose strengthens the cell walls present in a plant
enzymes and antibodies are made of proteins
water is the universal solvent.
10- C, all 3
1- cytoplasm contains about 85% of water, which helps in movement within the cells.
2- urine contains 95% of water, and it dissolve urea and salts in it.
3- plasma contains 90% of water, so we can say that water allows transportation of substances in the blood.
The answer is C.
Living organisms that live in the littoral zones in the ocean are used to frequent changes in temperature and in the salinity of the ocean water. For an organism to survive in this environment, it needs to have adaptive features that will increase its survival. The littoral zone is divided into three zones, which are high, middle and lower littoral zones. Organisms living in high littoral zone have adaptive features that make them more adapted to desiccation due to the long hours of sunlight to which they are exposed. The organisms are usually exposed directly to the air or they can be enclosed in burrows.
