Answer:
A XY or XY gamete fuses with a normal gamete (X or Y)
Explanation:
Meiotic nondisjunction is the phenomenon whereby chromosomes fail to separate during meiosis I or II. Meiotic nondisjunction leads to the formation of abnormal gametes I.e. gametes with additional or missing chromosomal piece.
The fusion of these abnormal gametes produced by nondisijuction with a normal gamete (X or Y chromosome). This leads to a condition called ANEUPLOIDY, which is a chromosomal disorder. In the case od Calix, XXY is an ANEUPLOIDY state that could have resulted because there was a fusion between a XX gamete and Y gamete or XY and X. The XY or XX gametes are produced as a result of nondisijuction.
Answer:
The correct option is D. The average mass of plants exposed to 3 g of herbicide was 10g.
Explanation:
As the vertical axis is labelled as average plant mass, it will make the y- coordinate.
As the horizontal axis is labelled as Herbicide (g/plant), it will make the x-axis.
The coordinates for the given value are (3,10). 3 will be the value of the x- coordinate. Hence, it will show the average mass of the plant at the plotted point which will be 3 g.
10 will show the value of the y- coordinate which will be the amount of herbicide given to the plant.
Hence, Dis the correct option.
Answer:
Longest interval during which no tree-cutting sample occurred: 9 years (1203 AD - 1212 AD)
First year in that interval: 1203 AD
Explanation:
Lets complete the question first.
Q) A study uses tree rings to determine the year in which a tree was cut. The data is shown in the leaf and stem diagram in the ATTACHMENT.
The three digits number in the left column represents centuries and decades AD. The numbers on the right represents the years.
For example, consider the first input in the diagram
119 | 5 6
which means it represents 2 samples.
1195 AD, 1196 AD.
The longest interval with no tree-cutting samples is found from 1203 AD to 1212 AD.
Answer:
The correct option is B: 2
Explanation:
Before meiosis takes place, the entire genetic material within the cell is replicated, this results in 2 copies of the 2n DNA. Since the person is heterozygous for the mutated allele, there is one copy of it present within one 2n set of chromosomes. Two of the 2n chromosomal sets means there would be two copies of it present in total and when the segregation event happens to create haploid cells, two of the cells will inherit the mutated copy.
Hope that answers the question, have a great day!
Answer:
The answer is Make reclamation required after mining operations have ended
Explanation:
If a company has removed the minerals out of the mining place, mined areas must go through reclamation, which returns land to a usable state after mining operations have ceased.
