That’d be B. Flagella.
flagella are hair-like appendages used for moving around, and are attached directly into the outer membrane of the cell.
Answer:
P generation: 1 purple flower (AA) : 1 white flower (aa)
F1 generation: 4 purple flowers (Aa) : 0 white flowers
F2 generation: 3 purple flowers (AA, Aa) : 1 white flower
Explanation:
Assuming the parents are AA and aa, the allele for white flowers is recessive, so there needs to be two of them for the trait to be expressed. Thus, the capital A purple allele that the other parent contributes will mask that white allele and all the flowers will appear purple. However, all of the offspring are Aa now, so when they are crossed, there's a 25% chance that they'll both contribute the lowercase a allele that codes for white flowers. Remember that if both of them give the lowercase a allele then the offspring will be aa and appear white.
idk about 10, i can't see the diagram
11. The moment magnitude scale is one of many seismic magnitude scales used to measure the size of earthquakes." The scale was developed in the 1970s to succeed the 1930s-era Richter magnitude scale.
use that ^
Answer:
Option (3)
Explanation:
Unconformity is defined as the gaps in the sequence of geological rocks. It is a geological contact that marks the boundary between the different types of rocks. In simple words, they are also known as the time of non-deposition. These unconformities have great significance in the field of geology. They are of 4 types, namely-
(1) Angular unconformity- The sedimentary rocks are initially formed and deposited in an area, after that the area is tilted and erosion takes place. Now, the new sediments are deposited forming an angle, which is commonly known as an angular unconformity.
(2) Non-conformity- When the sedimentary rocks are deposited over the igneous or metamorphic rocks, then it is known as the non-conformity.
(3) Para conformity- When the sedimentary rocks are deposited parallel to the ground surface, and absence of erosion activity, then these surface appears to be a normal (simple) bedding plane. This is known as the para conformity.
(4) Disconformity- When the sedimentary rocks are formed and undergoes erosion, then new sedimentary rocks are deposited over this and diminishes the unconformity. This forms a discontinuity.
Thus, the unconformity arises due to both erosion and lack of rock deposition.
Hence, the correct answer is option (3).
