If a cell at metaphase of mitosis contains 32 sister chromatids, chromosomes will be present in a g1 cell - 16 chromosomes.
During interphasechromosomes are fully or partially decondensed, in the form of chromatin, which consists of DNA wound around histone proteins (nucleosomes).
Thus, If a cell at metaphase of mitosis contains 32 sister chromatids, chromosomes will be present in a g1 cell - 16 chromosomes.

The correct answer is option C
The birds are adapted to live on the ground as this biome is grassland and have few variety of trees.
The trees there are scrub oaks, olive trees chamiso cork, pines, cork et cetera. Mainly this biome has shrubs and less number of trees.
The amount of rainfall that this biome receives is also very less so the trees are not very common there for the birds to survive.
Hence, birds are adapted to live on the ground and prey during night time.
the correct answer is C. on the ground
Oil spills and building damage, toxic chemical and sewage, and also flooding and mold infestations, all are the cause of Hurricane Katrina, hence option D is correct.
Hurricane Katrina is a strong storm that hit the United States and its coast, it really affects public health and devastates New Orleans, it damage all the buildings and remove all the water to be used.
This storm damaged all the buildings and spill the oil and it creating flooding conditions around that area. Many areas have toxic materials and sewage release at public places. The pressure of the winds is very stronger to cause building damage.
Therefore, all of the above is the cause of Hurricane Katrina, hence option D is correct.

The four symptoms in the human body caused due to air pollution are:
•Itching and redness in eyes: This is a very common symptom easily seen in the people as an effect of air pollution. Redness and itching is caused due to inflammation in eyes.
•Coughing: Coughing is also caused due to inflammation in the bronchi. The mucosa secreted encounters some foreign materials and as a result of this coughing starts.
•Sneezing: The nasal passage has some mucosal secretion which when encounters the dust particles starts sneezing.
•Nausea: Some people feel nausea due to gases that causes air pollution
The four different symptoms in the human body that may be caused by air pollution are coughing, sneezing, nausea, redness and itching in eyes.
Further Explanation:
The addition of any harmful substance or gases mainly referred as pollutant into the air so as to change the natural composition of air is called air pollution. In this various solid, gases, or liquid particles releases in the environment. These pollutants are release into environment in the high concentration that affect health, aesthetic or economic effects.

Answer:
Neurons, or nerve cells, are primarily located throughout the human body, but their highest concentration is within the nervous system, which includes the brain and spinal cord. So, the correct answer is not listed among the options, but neurons are mainly found within the nervous system.
Natural selection is the primary process that drives Darwin's theory of evolution, the correct option is a.
Darwin's theory of evolution is primarily driven by the process of natural selection. Natural selection is the mechanism by which certain heritable traits become more or less common in a population over successive generations. It occurs due to the differential reproductive success of individuals with advantageous traits that are better suited to their environment. Individuals with beneficial traits are more likely to survive and reproduce, passing on their advantageous traits to their offspring.
Over time, this leads to the accumulation of favorable traits within a population, while less advantageous traits become less prevalent. Natural selection is driven by various factors, including environmental pressures, competition for resources, and adaptation to changing conditions. It is a key driving force behind the diversity and adaptation of species observed in the natural world, the correct option is a.
