Answer:
B)
Explanation:
because Enzymes & antibodies are the only one with proteins ')
Seismic wave fields are recorded by a seismometer, hydrophone (in water), or accelerometer. The propagation velocity of the waves depends on density and elasticity of the medium.Velocity tends to increase with depth and ranges from approximately 2 to 8 km/s in the Earth's crust, up to 13 km/s in the deep mantle.
Answer:
What proteins,DNA, fat and sugar have in common is that they are biomolecules, or organic molecules, which all contain carbon and are necessary for the vital functions of living beings.
Explanation:
The principal biomolecules of living beings are proteins, carbohydrates or sugars, lipids and nucleic acids, such as DNA. All these molecules contain carbon in their composition and have hydrocarbon structures that may also have oxygen, nitrogen, sulfur and phosphorus in their composition.
Each of these biomolecules has a specific function and is indispensable for the development of life:
- <em><u>Proteins</u></em><em>: they are composed of amino acids and participate in the constitution of tissues, metabolic processes and the regulation of organic functions.
</em>
- <em><u>Carbohydrates</u></em><em>: they are the main energy substrate, participating in the metabolism that leads to obtaining ATP.
</em>
- <em><u>Lipids</u></em><em>: they are the main constituent of cell membranes, as well as constituting other organic molecules and being a reserve energy source.
</em>
- <em><u>Nucleic acids</u></em><em>: DNA and RNA participate in the process of storage and transmission of genetic information, being responsible for processes such as the synthesis of proteins and other molecules.
</em>
<u>The characteristics that have in common proteins, DNA, lipids and carbohydrates are their carbon-based composition, being organic molecules and being essential for living beings</u>.
Answer:
<h2>b) Anaphase II of meiosis
</h2>
Explanation:
1. Meiosis is the process of cell division in which one cell is divided into four daughter cell, each contains equal number of chromosome, half the number of chromosomes as compared to parental cell.
2. In meiosis I, DNA duplication occurs but the sister chromatids are not separated, only homologous pair of chromosomes are separated, so this is called reductional division.
3. In meiosis II, chromatids are pulled apart and and are separated into different chromosomes, so it is called equational division. There is no DNA duplication in meiosis II.
