Answer:
The correct answer will be options-B and D
Explanation:
The studies on the history of origin and evolution of life on Earth shows that all the organisms have evolved from a common descendant. This indicates that they possessed the same chemical-genetic or heredity molecule called Nucleic acid whether DNA or RNA.
DNA acts as the universal genetic material as it is present in all organisms except few. The process related to the DNA molecule is the same in all the organisms.
Since in the given question, the transfer of genes to plants via <em>Agrobacterium</em> and then the expression of the gene in plants shows that the passing of DNA has no barrier as DNA is the genetic material and the enzyme RNA polymerase recognized the gene which could help produce the mRNA from the gene.
Thus, options-B and D is the correct answer.
Tissues are a group of specialised cells with a common structure, origin and function. For example - epithelial tissue, nervous tissue, muscle tissue.
Plant tissue culture is a practice of propagating plants under sterile conditions, often to produce clones of a plant. Process of tissue culture: A small part of the plant is allowed to grow on a nutrient medium containing all nutrients and hormones necessary for the plant growth

Answer:
The correct answer is D. Reduced levels of circulating estrogens.
Explanation:
Estrogens prevent the loss of calcium and ensure its proper mineralization, thus preventing the bones from becoming brittle, maintaining the consistency of the skeleton and preventing osteoporosis. Osteoporosis is a skeletal disease in which there is a decrease in bone mass density. Thus, the bones become more porous, the number and size of the cavities or cells that exist inside them increases, they are more fragile, they resist shocks worse and they break more easily. Menopause is the definitive cessation of ovarian function that, externally, results in the disappearance of the menses and usually occurs around 50 years (the interval goes from 45 to 55 years). It is the gradual loss of calcium in the bones, which accelerates in the first years of menopause due to estrogen deficiency. At the beginning of the disease, there are no symptoms and, as it progresses, there is a tendency to suffer fractures, which leads to a decrease in height.
Answer:
a
Explanation:
the rate of oxygen consumption were lower than rates of photosynthesis. Photosynthesis occurs at a faster rate than oxygen consumption, more oxygen present in atmosphere than carbon dioxide
