Answer:
A nucleotide is one of the structural components, or building blocks, of DNA and RNA. A nucleotide consists of a base (one of four chemicals: adenine, thymine, guanine, and cytosine) plus a molecule of sugar and one of phosphoric acid.
Answer: Singing , as whistleing does not even involve your larynx
Explanation:
Autotrophs like plants use photosynthesis to take in carbon dioxide and put out oxygen. Animals like pigs and chickens breathe in oxygen to live. So the breakfast of bacon and eggs that depends on chicken and pigs, essentially depends on photosynthesis
If a species cannot reproduce then it will die out. This depends on the climatic conditions of the region. If there is a natural disaster, for example, it will affect a species' ability to reproduce. This reduces the number of diverse species on earth. Biodiversity is the recognised variety of different types of life found on the earth. It also measures the variety of number and variety of plants, animals and other organisms found in different ecosystems.
Explanation:
Since the 2 species co-inhabit a similar home ground, home ground isolation will be forgotten as an element keeping the 2species separate. There are but another broad class of mechanisms for reproductive isolation. One is behaviour. several birds specifically have terribly specific coupling rituals, together with coupling dances, specific birdsong, the event of specific coupling animal material, the discharge of specific pheromones and the building of a selected nest structure. Another broad class is mechanical isolation. you'll notice that the reproductive organ organs of specific species are terribly specific, and preclude different shut species from with success coupling. Another broad class is gametic isolation. for many species combos, it's inconceivable for the gametes to fuse with success to make a hybrid. If hybrid games do fuse, in several cases, the hybrids sterile, like mules as an example.
