The earth's tilt of 23.5 degrees to it's axis as it revolves around the sun causes seasons; summer, spring, winter and autumn. This is due to the orientation of the earth with respect to the sun that cause variations in how to sun rays 'strike' the earth. Consequently, there are variations in temperatures across the earth, over its complete revolution, causing seasons.
Answer:
Allele IA produces antigen A
Allele IB produces antigen B
Allele i produces No antigen
To predict the genotype the main thing is that I is dominant to i allele.
So, the ABO grouping genotype should be like this.
Genotypes Phenotypes
IA IA A
IA i A
IB IB B
IB i B
IA IB AB
i i O
This the main ABO blood grouping genotyping and phenotyping used in transfusion medicine. And this is the most abundant test performed in the blood banks for transfusion of blood and record management.

They are animal organelles that remove wastes from the cell
Answer:
Approximately 12,500 SARS-CoV-2 viruses
Explanation:
According to this question, the period described is 1mm in diameter. Since 1millimetre(mm) is 1000metre(m), this means that the period is 0.001m in diameter.
Also, the SARS-CoV-2 virus has a diameter of 80 nm (1nm = 10^9m).
Since 10^6nanometres (nm) or 1,000,000nm makes 1millimeter (mm), 80nm of the virus will be:
= 80/1,000,000
= 0.000080mm or 8 × 10^-5mm
To calculate how many of the SARS-CoV-2 virus will fit into the period, we divide the diameter of the period (in mm) by the diameter of the virus (in mm).
That is; 1 ÷ 8 × 10^-5
= 1/8 × 10^5
= 0.125 × 100,000
= 12,500
Therefore, approximately 12500 SARS-CoV-2 viruses will fit in the period.
Over 90% of all parasympathetic fibers are derived from the cranial nerve X, which is the vagus nerve.
The vagus nerve influences most organs below the neck. The activation of this nerve affects heart rate, blood pressure, production of stomach acid, movement of food through the intestines and breathing.
