First, a sperm identifies an egg, sticks to its jelly-like coating and strips to reveal parts of its cell membrane. In the second phase, the cell membranes of the egg and sperm cling together in an intimate embrace, before fusing to allow the DNA to meet.
Amorphous (eg. carbon black), or semi-liquid (eg. glass)
Discrete covalent molecules. eg CO2, N2,CH4. Covalent networks. eg SIO2
homogenous mixtures dissolve eg salt & water. hetrogenous mixtures do not dissolve eg chalk powder & water.
Some are solid (eg carbon) some are gaseous (eg oxygen) and one is liquid (bromine).
Both!Some protists are photosynthetic and therefore autotrophs eg Euglena and Chlamydomonas.Other protists feed like animals and so are heterotrophic eg Amoeba.
When mutual sperm exchange takes place. For example in gastropods.
It is on the fuses. eg: 10 = 10 amp, 7.5= 71/2 amp fuse
The manufactured sperm may have more genetic defects than a natural male sperm. Of course, natural sperm has its own defects, eg. infertility, genetic illnesses.
under the bonnet for main fuses(eg lights,ECU) and also some located under the dash on the drivers side remove the 2 pins on the cover to gain access.
to indicate possession as in "Fred's pen" to fill the space left by a letter omitted in a contraction eg doesn't in full is does not, the apostrophe takes the place of the missing o
active transport is nothing but where the ATP utilization takes place for the transport of ions through the semi permeable membrane. eg: transfer of na and k ions in plants,it also takes place in human beings in muscle cells and in nerve impulse transmission.etc
It doesn't depend on how much of sperm is produced for a man to be fertile but it depends on the quality of the sperm. Many lifestyle factors affect the quality of sperm, eg. Smoking, excessive alcohol intake , temperature at which the testicles are kept at, etc.
a setting of a story is where it is and the time ( eg where it is : euope and time 1800's or middle ages)
A microprocessor isn't input or output. It is the middle, it is the center. It takes input (from eg a keyboard) and generates output (for a eg a printer).
In a controlled environment it will be okay for 4-6 hours. In the vagina sperm can live for 5 days. No sperm does not die immediately after touching skin.
A place of value is, in maths where the digits, eg. tens hundres and thousands etc are place values.
In a place that many people go/ use. Eg train stations
