Answer:
oxygen because that's one of the substance that plants produce.
You can also do this by the process of elimination. Knowing that atrazine impedes the production of substances in plants, we know that it can't be DNA and Phospholipid. Carbon Dioxide is used by plant, not produced; thus, oxygen is the answer.
Answer:
Explanation:
This is because ferns are vascular plants i.e they have vascular tissues which are xylem and phloems which help to conduct water and nutrients while mosses are non vascular plants.
2. Ferns sporophytes are differentiated into true leaves, stems and true roots while mosses lack true roots, stems and leaves.
Underground stems are modified part of plants that are derived from stem tissues which grow under the ground. Underground stems grow beneath the soil. Examples include Rhizomes, ginger, tubers e t.c.
When you decide to execute a maneuver, you will need a control zone of approximately TWELVE TO FIFTEEN seconds. Maneuvering involves reversing around a corner, either to the left or to the right in order to changing the direction of the vehicle. <span />
Answer No 2:
The correct option is C. <u>Substitution of 3rd N-base to go from UCU TO UUU </u>has the potential to cause more damage.
Answer No 3:
UCU codes for the amino acid serine whereas the code UUU is for phenylalanine. A change in this base has caused the entire amino acid to change which will result in the formation of the wrong protein.
Whereas the changes in the base sequence of the options A and B do not change the amino aids being made. Hence, the changes in options A ans B will be less damaging then the option C.
Answer 4:
In the field of genetics, a stop codon can be described as a signal which stops the translation. It is a three nucleotide sequence which is recognized as a terminator.
If stop codon is not present at the right place, then the process of translation will not terminate at the right place and wrong proteins will be made.
Answer:
The second pair of grandparents have approximately 12 to 19 boys as grandchildren.
Explanation:
The probability of a grandchild being a girl or a boy is same, i.e., 
.
The first pair of grandparents have 4 grandchildren.
The second pair of grandparents have 32 grandchildren.
If first pair of grandparents have between 40% to 60% boys as grandchildren then the number of boys are in the limit,
Thus, the first pair of grandparents have approximately 2 to 3 boys as grandchildren.
If second pair of grandparents have between 40% to 60% boys as grandchildren then the number of boys are in the limit,
Thus, the second pair of grandparents have approximately 12 to 19 boys as grandchildren.
So, it is clear that the second pair of grandparents are more likely to have between 40% and 60% boys as grandchildren.
Also according to the law of large numbers as the sample size increases the probability of an event gets closer to the theoretical probability.
