<h2>Answer:</h2>
The correct answer is option A which is an abnormal male with nondisjunction.
<h3>Explanation:</h3>
The karytope is the complete picture of chromosomes present in a cell of an individual.
It is used to study the chromosome number and abnormalities related with chromosome numbers.
Chromosomal nondisjunction is the consequence when the homologous chromosomes are not completely separated from each other during meiosis.
While chromosomal translocation is the crossing over of genetic material between two chromosomes.
Only chromosomal disjunction can be seen from the karyotype.
The water enters the xylem first by osmosis. Water moves from the soil to the root hair cell down a water potential gradient, and to the root cortex cell from a higher water potential to a lower water potential, this process will be repeated until water enters xylem. Because transpiration is occurring in the leaf, water is lost so there is a lower water potential inside the leaf. Osmosis moves water from the xylem to the leaf because the xylem has a higher water potential. Water moves from the xylem to the cells of the leaf. This pulls water up the xylem via cohesion which is the process of water molecules attracting each other and sticking together. Water does not fall down the xylem as here is adhesion which is the process of water molecules sticking to the inside of the xylem.
Answer:
Which data help hydrologists predict floods?
Impermeable land area
Snowpack
Explanation:
Impermeable land area
, Snowpack
The above factors are very essential to an hydrologist to predict floods though other factors such as topography, drainage among others are also inclusive to make the prediction rightly.
genotypes is 1:2:1 & phenotypes is 3:1
