Answer:
The correct answer would be option A.
Explanation:
Gina's model lacks many important factors about the particular study of damage to tree bark in the forest. This model does not explain the number of animals entering a particular area of forest.
This model does not tell, how much damage has been done. It also fails to tell what type of damage the tree has faced. It does not explain what type of bacteria evolved or carried by the animal.
Thus, the correct answer would be option A.
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.
Answer:
Particulate matter
Explanation:
An electrostatic precipitator is an air filter. For this reason, we can say that the air pollutant that would be captured if electrostatic precipitates were installed in the exhaust systems would be the particulate matter.
An electrostatic precipitator is very effective in controlling atmospheric pollution in an industry, factory or even a plant that emits polluting gases into the atmosphere. This equipment captures the polluting particles, leaving only the clean private gas to be transferred to the atmosphere.
Answer:
A. the two genes on chromosome 1 are more than 50 mu apart.
Explanation:
Two or more genes present on the same chromosomes are the linked genes. Linked genes do not assort independently and do not exhibit crossing over. Therefore, the linkage of genes results in deviations from Mendel's law of independent assortment. However, if the linked genes are present far from each other on the same chromosome, they may exhibit crossing over.
The greater the distance between the linked genes, the higher are the chances of crossing over. Crossing over of linked genes would result in some of the progeny to have the new gene combinations as it occurs during an independent assortment of two genes. Therefore, Mendel observed an independent assortment of two genes present together on chromosome 1 since they were present far apart from each other (more than 50 mu apart).
Answer:
Nervous system
Explanation:
The nervous system consists of the the brain and the nerves and the damage was done to the nerves that run all the way down his leg.
