The answer is D. lose apical dominance and grow lateral branches
Apical meristem is a meristem tissue found at the branch tips. When it is active, tree grows in height and the lateral branches will not be as dominant. Imagine conifers and their branches. However, when apical meristem is removed, that apical dominance will be lost, and the lateral branches will become more dominant, so the tree will look more branchy.
The correct answer is option C
The demand for a better life increased the pollution in the society. The increased pollution in the environment led to many health problems.
The Nuclear power plant creates radioactivity and thermal pollution.
The water used in the nuclear power plants is very warm and causes thermal pollution as it is released into water bodies.
The nuclear power plant uses radioactive substances like uranium and the waste that is left is radioactive waste.
A concrete population is a population that consist of definite
or concrete observations and those that really exist. Examples are: all the
students of a class, the alphabet, all the workers in the factory. While hypothetical
population on the other hand, are population that consist of imaginary or
hypothetical observations. It is not well defined and the samples had not been
selected from existing population. Examples for this are: all
possible toxicity measures of a new drug, GPAs of all young adults (including
those not in school) and the
number of years’ people would have lived if they had quit smoking.
