Answer:
D. the law of crosscutting relationships
Explanation:
The law of cross-cutting relationships can help explain the age of the rock as it relates to the surrounding rock.
This law is one of the premise of relative dating. The relationship between the intrusion and rock body or country rock is used to discern their age.
- When intrusions cross-cuts the host rocks, they are usually younger.
- The host rock must haven emplaced before the intrusion sets in
- The intrusion utilizes weak planes within the rock body to cool and solidify.
- Now, when they are emplaced, then a vein or other intrusive bodies forms.
Answer:
The virus that generates chickenpox disease is a virus of the family called "herpes" where once they infect the human organism they are not eliminated by human defense, but are reserved and coexist in the organism in the lymph nodes, and when faced with immunodeficiency situations for certain reasons, it generates their reactivation, manifesting a recurrence of the disease.
Explanation:
The chickenpox virus is called the Zoster chickenpox virus, once it infects the human in his childhood, it settles in the ganglion near where it is inactively inoculated.
This is reactivated again manifesting shingles or herpes zoster in adulthood and in situations of immunodeficiency as in those malnourished humans, or who are exposed to long hours in the sun, or who suffer stressful situations.
Shingles is a disease that manifests itself in a very painful way (more than chickenpox) in the form of scabs and vesicles in different possible areas.
It is used by every living cell.
Cellular respiration is a process of combining oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.
The correct answer for this question is A. Law of segregation.
All individuals have two alleles for a given trait. According to Mendel's Law of segregation, these alleles are passed down one each from both mother and father.
Explanations;
According to this law of segregation the allele pairs separate or segregate during the formation of gamete, during the process of meiosis, leaving each cell with a single allele for each trait, and randomly unite during fertilization. One pair of allele comes from the mother while the other pair comes from the father, and joins together to form a diploid cell. Therefore, organisms inherit two alleles for each trait one from each parent.
