Answer:
meiosis
Explanation:
Down syndrome is an abnormality that occurs on chromosomes 21, it occurs because chromosomes 21 cannot be separated in meiosis, the pair of chromosomes 21 do not separate and go together to one of the daughter cells. In this way, the oocyte or the resulting sperm will have 24 chromosomes instead of 23. When in conception that oocyte or sperm joins the germ cell of its partner that contributes the 23 chromosomes, the total sum of chromosomes that will have the first cell of the new conceived being will be 47.

Answer:
t = ln (N/N°)/(-0.0239)
Explanation :
The decay law is represented as
N = N°e^-kt
Where N is the final number of atom,
N° is the initial number of atoms
k is the decay constant
t is the half-life.
From the above we have,
N/N° = e^-kt
take ln of both sides
ln (N/N°) = -kt
t = ln(N/N°)/-k
At half life, N/N° = 1/2
Therefore, t = (ln 1/2)/-k
t = -0.693/-k
But t = 29 sec
29 = -0.693/-k
k = 0.0239 s^-1
Therefore,
The formula will be
t = ln (N/N°)/(-0.0239)
Answer:
If I am concerned about biodiversity, I would plant Genetically Modified (GM) crops given the reason that they have an advantage above any other species of crop.
Explanation:
Genetically modified crops (GM crops) are plants utilized in agribusiness, the DNA of which has been changed utilizing hereditary designing strategies. Plant genomes can be designed by actual strategies or by utilization of Agro-bacterium for the conveyance of arrangements facilitated in T-DNA parallel vectors.
Much of the time, the point is to acquaint another attribute with the plant which doesn't happen normally in the species. Models in food crops incorporate protection from specific irritations, infections, natural conditions, decrease of waste, protection from substance medicines (for example protection from a herbicide), or improving the supplement profile of the harvest. Models in non-food crops incorporate creation of drug specialists, bio-energizes, and other mechanically helpful merchandise, just as for bio-remediation.
