How could farmers increase the yields of their crops without using
genetically modified organisms?
Answer:
The reduction of losses by pests, viruses and weeds that compete for soil nutrients, together with savings in phytosanitary products and fuel, indirectly increase the final yield when compared with conventional crops.
Explanation:
what scientist determine the rule that A always pairs with T and C alway pairs with G
Explanation:
These base pair relationships are often called Chargaff's rules of DNA base pairing, named after the Columbia University scientists who observed that there are equal molar concentration of A & T, as well as G & C in most DNA molecules.
Answer:
Erwin Chargaff
Explanation:
Erwin Chargaff found that in DNA, the ratios of adenine (A) to thymine (T) and guanine (G) to cytosine (C) are equal.

If the dry bulb temperature is 46,and the dew point is 11 degrees celsius,what would be the difference between the wet-bulb and dry-bulb temperatures?
Answer:
Dew is the condensed water that a person often sees on flowers and grass early in the morning. Dew point varies depending on the amount of water vapor present in the air, with more humid air resulting in a higher dew point than dry air. Furthermore, the higher the relative humidity, the closer the dew point to the current air temperature.
Explanation:
If an organism has a hapoloid chromosome of 8 which of the following is the organism diploid chromosomes and why
Answer:
if I remember right, a diploid is twice the amount of a haploid because diplood are pair chromosomes. So if there is 8 haploid there will be 16 diploid.
Explanation:
To find the diploid put the n of 2n.

please help me- how does rock layer h compare to rock layer m?
Answer: Rock layer H is much newer than rock layer M. If all layers were perfectly stacked, the lower layer would be older. However, since we can see Layer H was probably formed by a crack that was filled with magma, Layer H will be newer.

Gregory Mendel is widely considered to be the father of genetics
Option A is correct
How do we explain?Gregor Mendel was an Austrian monk and botanist who is considered to be the father of genetics. He conducted experiments on pea plants and was able to formulate the laws of inheritance, which are the basic principles of genetics.
Mendel's work was not widely recognized until the early 20th century, but it has since had a profound impact on our understanding of genetics. His work laid the foundation for the study of genetics and has helped to advance our understanding of how traits are passed down from parents to offspring.
Therefore, Option A is correct

During meiosis I, how could you have arranged the chromosomes in a different way? How do the differences affect the end result of meiosis??
Explanation:
Meiosis is the formation of reproductive cells, like the egg in the fallopian tube; if not fertilized by sperm, it is expelled by the menstrual cycle.
Some conditions during fertilization can be disrupted by an egg attaching to the fallopian tube instead of the uterus causing an ectopic pregnancy. Arranging chromosomes in a different way causes congenital defects like color blindness, crohn's disease down's syndrome, etc.
