<span>All children have a 50/50 chance of being male or being female. There is no true predisposition of having all male or all female children because it depends on the strength of the sperm and which sperm reaches the egg first. If the stronger sperm is an X chromosome sperm cell the child will be female while if the Y chromosome sperm cell is stronger then the child will be male. With women it does not matter because women have 2 X chromosomes versus men who only have 1 X and 1 Y. So the probability that the second child to b born a male will be 50/50 just like any child that is born.</span>

The total amount of chemical energy produced by autotrophs, such as plants and phytoplankton, is called gross primary production
natima [27]

Answer:

This question lacks options, the options are:

a) Negative primary production

b) Net primary production

c) Secondary production

d) Negative secondary production

e) Positive primary production

The correct answer is b.

The total amount of chemical energy produced by autotrophs, such as plants and phytoplankton, is called gross primary production. The energy that remains after plants use some of the gross primary production to fuel their own metabolism is known as <u>net primary production</u>.

Explanation:

Net Primary Production (NPP) is the value that results from the difference between gross production and respiration of the primary producers themselves. It manifests as growth and / or reproduction. It represents the matter and energy available for the next trophic level, that is, the net primary production is what is left after subtracting the energy that plants use for their metabolism or maintenance (such as breathing, tissue construction and reproduction).

-BARSIC- [3]
This statement about matter is true: MATTER IS MADE UP OF ATOMS AND HAS MASS. 
Matter is defined as anything that has mass and occupies space. The mass of an object is the measure of the extent to which the object can resist a change in its direction when a force is applied to it. A matter is usually made up of atoms, which is defined as the smallest component of any matter. Therefore matter is made up of atoms and it has mass.
