Genetic transmission is the mechanism that drive evolution.Asexually reproducing organisms reproducing organisms reproduce using mitosis, while the sexually reproducing organisms reproduce using meiosis.
Both these mechanisms are involved in duplication of DNA which then get passed to offspring and RNA is key component in the duplication of DNA. The genetic information heritable biological information coded in the nucleotide sequence of DNA or RNA.
Genetic material is includes genes and DNA which control the development , maintenance and reproduction of organisms. These messages is passed from generation to generation through inherited units of chemical information. It consist of only two transcription and translation they known as gene expression , during this process of transcription store in gene DNA is passed to similar molecule called RNA in nucleus.

Explanation:
Edit
The upper mantle of Earth is a very thick layer of rock inside the planet, which begins just beneath the crust (at about 10 km (6.2 mi) under the oceans and about 35 km (22 mi) under the continents) and ends at the top of the lower mantle at 670 km (420 mi). Temperatures range from approximately 200 °C (392 °F) at the upper boundary with the crust to approximately 900 °C (1,650 °F) at the boundary with the lower mantle. Upper mantle material which has come up onto the surface is made up of about 55% olivine, 35% pyroxene and 5 to 10% of calcium oxide and aluminum oxide minerals such as plagioclase, spinel, or garnet, depending upon depth.
Answer:
saturated fats:single bonds
trans fat: one doubled bond
<u>Answer</u>:
1.a) Species. It is the lowest taxon and represents the scientific name of the organism.
b) The species name is part of the binomial system of nomenclature developed by Linnaeus.
Thus it is composed of two parts each with its own writing rules (ex. gray wolf - <em>Canis lupus</em>):
A. the genus or generic name
- written first
- always underlined or italicized
- the first letter is always capitalized
ex. <em>Canis</em>
B. the specific epithet or species name
- is written second
- always underlined or italicized
- never capitalized
ex. <em>lupus</em>

2. The results should always be the same. A dichotomous key is an identification tool based on a series of choices between alternative characters (dichotomous = divided into two parts). Thus, there is no room for subjective observation that may lead to another result. If the morphological traits of the organism are correctly identified, the the result should always be the same. Any differences occur due to errors on the scientist's part.
Answer:The electron transport chain is a series of complexes that transfer electrons from electron donors to electron acceptors via redox reactions, and couples this electron transfer with the transfer of protons across a membrane. The electron transport chain is built up of peptides, enzymes, and other molecules
