Answer: The correct answer is- D certain factors are dominant and other factors are recessive.

Mendel was interested in knowing the offspring that is produced from the cross pollination (that is from two different plants) as he wanted to study different traits of pea plant.

For doing so, he first removed the anthers of one plant (to prevent self pollination) and then transferred the pollens of one plant into the stigma of another plant.

When he allowed the cross pollination of purebred pea plant with other plant, he observed that some factors are dominant (such as tall height of pea plant, which masks the expression of recessive factors) and other are recessive (such as dwarf height of pea plant).

Thus, option D) is the right answer.

The transfer of genes from one organism to another is called genetic engineering. This is new technology used to change the gene
nikklg [1K]

Answer: C) GMOs, genetically modified foods engineered in a lab to produce desirable traits.

Explanation:

The genetic engineering involves the insertion of genes from other organism to the host organism so as to make up genetically modified organism. Some unwanted and default genes are also removed from the organisms so that their body function properly.

The genetically modified foods are the examples of genetic engineering. This is done to produce desirable traits in the food crops. In plants both plants and animal genes are inserted to improve the yield of crops, and to improve their quality. In animals, the insertion of genes of other animals is likely to improve the milk and meat yield.

Is it true that mosses create tiny crevices in the rocks with acid​
Novosadov [1.4K]

Answer:

yea

Explanation:

Together, the organisms that form lichens make acids that slowly dissolve the rock on which they grow, which makes tiny crevices in the rocks. ... Mosses send their hair-like structures into the crevices the lichens made in order to anchor themselves on the rock. Then the mosses grow bigger.
