Answer:
Replacement rate
Explanation:
In biology, replacement level or replacement rate refers to the amount number of offspring required to be produced to keep the level of population at a stable state without causing it to much decease.
Scientists use the replacement rate of plant and animal specie to assess the rate at which the population is reproducing at a stable level or are at some threshold zone and need to be taken care of.
Here in question, we see that some specific properties of mustard plants are focused that, plant survives only one month during which it produces 50 flowers. each flower produces a fruit containing 20 seeds.
It clearly do not depicts the population size of mustard plant, or niche or fitness, it just describe the replacement rate that how many offspring does mustard plant produce to keep its population at a stable or steady state without being getting into a danger of extinction.

So... for the element of PHOSPHORUS, you already know that the atomic number tells you the number of electrons. That means there are 15 electrons in a Phosphorus atom. Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and five in shell three.
There is an increasing levels of biological contaminant
procedures because they are necessary in preventing spores from becoming as
dormant and that they are also responsible for preventing bacterial infections
and as well as resistance of viruses. The level of biological contaminant
necessary to complete experiments is to have a biological level of bio safety
level 1 when there is a need of minimal potential hazard to the ones conducting
the experiment.
The answer is Ocelli.
The brainest answer with be appreciated.
