probably because they have the characteristics of life just like plants and us
Answer:
Most cancer-causing DNA changes occur in sections of DNA called genes. These changes are also called genetic changes. A DNA change can cause genes involved in normal cell growth to become oncogenes. Unlike normal genes, oncogenes cannot be turned off, so they cause uncontrolled cell growth.
Answer:
Some sweet-pea plants have purple flowers and other plants have white flowers. A homozygous variety of pea that has purple flowers is crossed with a homozygous variety that has white flowers. All the F1 have purple flowers. When these F1 are self-fertilized, the F2 appear in a ratio of 9/16 purple to 7/16 white. Show your work.
A) Give genotypes for the purple and white flowers in the F2 generation.
PP x ww= Pw, Pw, Pw, Pw F1 generation
Pw x Pw= PP. Pw, Pw and ww F2 generation
3 purple and 1 white flower
B) Draw a hypothetical biochemical pathway to explain the production of purple and white flowers in sweet peas.
Explanation:
Answer:
A) DNA and RNA both contains codes that contribute to protein production. DNA remains in the nucleus while RNA more directly contributes to protein synthesis
Answer:
B. Lactate
Explanation:
When we carry out strenuous physical activity, we begin to breathe heavily because our body prefers to generate energy using an aerobic method, in this way it tries to enter as much oxygen as possible, but in these physical activities that require effort, a greater amount of energy is needed. From which we can produce aerobically, this energy comes from glucose through glycolysis in which glucose is broken down or metabolized into a substance called pyruvate through a series of steps. When the body has plenty of oxygen, pyruvate is shuttled to an aerobic pathway to be further broken down for more energy, but when oxygen is limited, the body temporarily converts pyruvate into a substance called lactate, which allows glucose breakdown and thus energy production to continue.
