Answer:
The correct answer is letter D. Conventional breeding
Explanation:
In conventional genetic improvement a plant is crossed with another of the same species, with no incorporation of genes from another organism into the plant's genome, requiring repeated crossings until reaching the desired improved cultivar. Only in transgenics or genetic engineering are genes from another organism incorporated into the plant's genome.
Sexual reproduction is a process involving the fusion of two gametes to form a zygote. Gametes are special reproductive cells produced by meiosis. It produces genetically dissimilar offspring. Offspring may inherit beneficial qualities from both parents and there is a greater genetic variation in the offspring, leading to species that are better adapted to changes in the environment.
It needs to be understood if this really affects the cow or the consumer in any negative way.
Answer:
These vents contribute dissolved minerals to the oceans, which is one reason the oceans are salty. Rivers and surface runoff are not the only source of dissolved salts. Hydrothermal vents are recently-discovered features on the crest of oceanic ridges that contribute dissolved minerals to the oceans.
