I do not know if it’s a bad thing but it’s okay so if you don’t do have a great day
Answer:
7 hours
Explanation:
Given, generation time of the species is 1 hour which means that after every 1 hour the cells double in number.
At 0 time = 100 cells/ml
After 1 hours = 200 cells/ml
After 2 hours = 400 cells/ml
After 3 hours = 800 cells/ml
After 4 hours = 1600 cells/ml
After 5 hours = 3200 cells/ml
After 6 hours = 6400 cells/ml
After 7 hours = 12800 cells/ml
Thus, after 7 hours the culture will contain approximately 10000 cells/ml.
Solution:
A frame of reference is also a system of lines and clocks that you can use to measure the position and motion of a set of objects and events in relation to each other.
It is a system of geometric axes in relation to which measurements of size, position, or motion can be made.
It might seem strange to use a coordinate system moving relative to the earth. But, for instance, the frame of reference moving along with a train might be far more convenient for describing things happening inside the train. It is particularly important when describing an object's displacement.
If the position of any one at a point O then he has a set of coordinate axes to measure the position of a body. x.y.z in units in meter. So he locates the point as x meters along x-axis , y meters long y-axis and z meters along z axis. along z axis.
These three axes are perpendicular to each other then are called orthogonal axes or frame of reference. The time of an event can be measured by a clock.
The frame is said to be attached to the observer…as his scale of measurement is his own.
By this statement that he found a body P at (x,y,z) he is locating the body in space and if the time was t then the location is in space-time.
Thus we get that changing frame of reference will affect the system of the Earth.
Answer:
There is an accumulation of genetic mutations in the DNA of sperms due to its constant mitosis.
Explanation:
The germinative cells that will become sperms are under constant mitosis. During this process, DNA mutations can happen and be transmitted from one generation of cells to the other as the years go by, and more cell divisions take place, more mutations the DNA in the sperm will have. When the number of mutations reaches a certain level, his child will express these mutations and have autism.
The egg of the mother is not a factor because the germinative cells in women are not under constant mitosis, so there is not an accumulation of gene mutations. Women are born with an exact number of eggs for all their life.
