3 copies of chromosome in karyotype shows that person has genetic disorder called down syndrome.
What do you mean by karyotype?A karyotype test examines the structure, shape, and number of chromosomes in your body. The sections of our cells that hold your genes are called chromosomes.
Instead of having one copy of chromosome 21, an egg or sperm cell may preserve both copies. If this egg or sperm is fertilized, the baby will be born with three copies of chromosome 21. This is referred to as trisomy 21. Trisomy 21 is present in around 95% of people with Down syndrome. Instead of the usual two copies of chromosome 21, each cell in the body has three copies of chromosome 21 in this kind of Down syndrome.

From 2007 to 2010, the mink population stayed fairly consistent, but in 2010, the population dramatically decreased. Which of the following could describe what happened to the population of minks?
The mink population ran out of space to live so many died
A catastrophic event occurred like a disease or big natural disaster that quickly wiped out a large number of mink.
There were more voles for the mink to eat, so their population increased
The bears began to eat the mink in 2010 so the population of minks decreased.
The most likely event that led to a sudden decrease in the population of mink in 2010 would be a catastrophic event. The correct option would be B.
Decrease in populationA sudden and sharp decrease in the population of an organism can be caused by a host of factors. These include:
catastrophic events such as disease outbreaks, natural disasters, famine, etc. a sudden appearance of predators in the environmentIf the predator has always been in the environment with the population of the organism, this will not result in a sharp decline in the population. A population of predators suddenly joining the environment may be the only cause for a sharp decline in the population of the organism.

what does the graph predict for the future? A Less air pollution.
B Forest overgrowth.
C Reduced demand.
D Resource depletion.
The graph predict resource depletion because the supply and consumption of forests when the consumption rate and population growth rate are both low.
What are the consequences of the depletion of natural resources?The consequences of this ecological excess are increasingly evident, with imbalances such as the extinction of species, scarcity of fresh water, soil erosion, loss of biodiversity and global warming.
Reaching this limit means that all the resources used for the survival of humanity are depletion and we are in “debt” to the planet, in this case it is the graphic representation of this depletion.

What is cell?
Cell is defined as the base of life as it is the structural as well as functional unit of life. Cell is made up of pre existing cells and the cell contain various cell organelles such as mitochondria, endoplasmic reticulum, ribosomes, golgi appratus, nucleus, and cytoplasm.
Basically, cell is of two type one in prokaryotic and another one is eukaryotic. The prokaryotic cell is known as pre mature cells as they do not contain cell organelles and eukaryotic cell are known as advanced and developed cells as they contain several cell organelles.
The unicellular animals are made up of single cell and all the functions carried out in a single cell like amoeba and multicellular organisms are made up of multiple cells and there is specific cell for specific functions.
