Answer: Natural selection can be defined as the differential survival and reproduction of members of the population of a species that have suitable traits to survive in a population of species.
Explanation:
The punctuated changes in the population of species have been found inordinately faster in the geological time scale, but changes per-generation have been relatively slow. Also, the rate of evolution in such a population is also slow. The punctuated changes in the population are because of evolution but the per-generation changes are the outcomes of the natural selection, in which only the beneficial traits are passed from one generation to another.
Answer:
The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.
Explanation: hydrogen bonds
The answer is B.
Fermentation(an anaerobic process) is a way of harvesting chemical energy without using either oxygen or any electron transport chain.
Fermentation consists of glycolysis plus reaction that regenerate NAD+ by transferring electrons from NADH to pyruvate or derivatives of pyruvate.
There are many types of fermentation, lactic acid fermentation and alcohol fermentation are the most common two.
Tap Root. Plants with a tap root system have a large dominant central root where other lateral roots sprout. These lateral roots are called secondary roots. Examples of plants with taproot system are: sugar beet, parsnip, carrots, radish, dandelion and beetroot.
Answer:
The correct answer s - by the photosynthesis process.
Explanation:
Plants use the sunlight to convert the atmospheric carbon dioxide and water to oxygen and glucose for their food and energy, this process is called as photosynthesis. In This process, glucose is formed that is linked together to form the storage carbohydrate form, starch, that can use by plants later and store in the different parts of the plants.
In plants like potato and sweet potato or the plants that has tuber or grains, store the starch in their tuber or grains by transporting the starch to the these parts.
