An answer might be - <span>Any of a group of complex organic macromolecules that contain carbon, hydrogen, oxygen, nitrogen, and usually sulfur and are composed of one or more chains of amino acids. Proteins are fundamental components of all living cells and include many substances, such as enzymes, hormones, and antibodies, that are necessary for the proper functioning of an organism. They are essential in the diet of animals for the growth and repair of tissue and can be obtained from foods such as meat, fish, eggs, milk, and legumes.

<span>Soil degradation by human activity is a huge global issue since it deteriorates the soil and there is a reduction in quality of the soil and its productivity. The region that is facing this issue largely is Asia. This is the reason solving this issue is now an international agenda.</span>
<span>There is heat from the Earth’s core. Unfortunately, even thought the Earth is round, this heat isn’t evenly distributed. Therefore, sometimes the pressure from the heat in some areas can create currents that move the plates across the Earth’s surface.</span>
Answer:
Answer is A.
Explanation:
The regulation of cell division and proliferation are the activities of a group of protein known as Ras protein , which are found near cell membranes. And abnormal Ras protein bring about uncontrolled cell division resulting in tumors development.
Answer:
In the dominant- recessive model of inheritance, the dominant allele fully suppresses the recessive allele. As a result, heterozygous individuals produced show the effect of the dominant trait in them. For the recessive trait to occur, both the alleles of the gene should be recessive in the organism.
In co- dominance model of inheritance, the dominant allele is not fully dominant over the recessive trait. As a result, heterozygous individuals show both the dominant and recessive characteristic in them. For a dominant trait to occur, both the alleles should be dominant. For a recessive trait to occur, both the alleles should be recessive.
