Explanation:
Like all living organisms, plants use deoxyribonucleic acid (DNA) as their genetic material. The DNA in plant cells is found in the nucleus, the mitochondria and the chloroplasts. The latter two organelles are descendants of bacteria that were captured by a eukaryotic cell and have become endosymbionts.
Answer:
Genes are important for determining function, but nutrition modifies the extent to which different genes are expressed and thereby modulates whether individuals achieve the potential determined by their genetic background. Nutrition modifies both physical and cognitive aspects of performance.
Explanation:
which means it determines (firmly decide) on how much you exercise and what you eat, for an example if you eat unhealthy all the time like alot of dessert or sweets and ssalty foods then it gives you a unhealthy genetic backround(in which each gene functions).
Answer:
The animals present body structure is due to evolution. It is seen in each part including the structure of the heart. The vertebrate heart becomes complex from a simpler form.
Invertebrates, the heart of fishes is two-chambered having one auricle and one ventricle. The deoxygenated blood gets purified in the gills. They are aquatic and no lungs for breathing. The hearts pump a mixture of oxygenated and deoxygenated blood to the body.
The amphibians and reptiles have 3 chambered heart as they lead terrestrial mode of life. The gills modified into the lungs. The left auricle receives pure blood and the right auricle receives deoxygenated blood. The blood purified in the lungs and in the ventricle, both types of blood get a mix. The ventricle pumps the mixed-blood throughout the body.
In the case of birds and mammal, the heart is 4 chambered and the oxygenated and deoxygenated blood are separated. These two are higher vertebrates. No mix of pure and impure blood, the body receives only the oxygenated blood.
This shows to construct the phylogenetic tree of vertebrates - the fishes should be in the bottom, and above it amphibians, reptiles, then, mammals and birds on the top branch of the tree. As the chambers and structure of the hearts modified one after another.
