Answer: a food-growing practice that uses no synthetic fertilizers, insecticides, fungicides, or herbicides
Explanation:
Organic agriculture is a process of crops of economic importance. It is an integrated farming system that ensures the sustainability, enhances the fertility of the soil, and that is biological diversity.
It prohibits the use of synthetic pesticide or insecticides, fungicides, synthetic fertilizers, growth hormones, antibiotics, and genetically modified organisms for the growth of crops. It utilizes the fertilizers of organic origin, like manure, compost, bone meal and also supports the crop rotation. It supports the biological pest control and fostering of insect predators.
Answer: option C) enables the "let-down" reflex to occur when a woman breastfeeds her baby.
Explanation:
Oxytocin is a hormone secreted by the posterior pituitary gland. It stimulates the contractions of smooth muscles such as
- uterus facilitating childbirth
- ducts of the mammary glands resulting in ejection of milk. Thus, it is also called as milk-let-down-ejection factor.
So, option C is the correct answer
Answer:
The organisms in which are able to adapt and become stronger.
Explanation:
In Darwin's theory, only the strongest and capable of adaption survive to natural challenges.
Genotype: 50% Aa and 50% aa
Phenotype: 50% Dimples and 50% no dimples
Explanation: Using a punnet square, we can figure out that the mother is recessive and the father is heterozygous. Putting the mother at the top of the square and the father on the side, you end up with the results above by crossing each square with the corresponding letters. It's okay if the letters end up backwards. Just be sure to face them the right direction, capitals being first once you finish.
Hope this helps!
Answer:
Option). the uneven cutting by most restriction enzymes
Explanation:
Sticky ends can be defined as over-hanged DNA fragments of unequal length, having a terminal portion with unpaired nucleotides. These fragments are formed by a staggered cut on DNA molecules wit the help of restriction endonuclease enzymes.
These ends have complementary nucleotide bases that allow complementary base pairing between bases, and thus, known as sticky ends.
Thus, the correct answer is 'last option.'
