Answer:
Nucleus and acrosome
Explanation:
Human sperm is the male gamete or sex cell formed by spermatogenesis. It is made of a head, neck, a middle piece and a tail. The sperm head consists of a haploid nucleus and anterior to nucleus, an acrosome. The nucleus contains DNA and nuclear protein and it transfers genetic features from the male to the next generation. The acrosome contains an important enzymes, hyaluronidase and acrosin. These enzymes help to enter head into an ovum.
The answer is false.
The two main nuclear processes are nuclear fission and nuclear fusion.
In fission, a large nucleus is bombarded with a high energy neutron, resulting in the breakdown of the nucleus and the release of two smaller nuclei along with neutrons and high amounts of energy.
In nuclear fusion on the other hand, two smaller atomic nuclei possessing high amounts of energy to form a larger nucleus, with the possible release of neutrons. This process is also highly exothermic.
Lake is a region filled with water (could be fresh or salt water) that surrounded by Land. (humans on average couldn't cross a lake without vehicle)
Ponds is actually simlar with lands but have considerably smaller size (could be crossed without vehicle_
Stream of pools is a stretch from river area that had noticeable water movement and above average depth.
Tungsten (W) has six electron shells. You get this number by counting down to the row the element is on. The row number is the number of electron shells.
Sound is transfered with vibrational wave.
Vibrational wave are transverse wave.
vibration wave require medium to transfer so sound can't travel in space
