How do atoms form a new substance

Biology
1 answer:
dolphi86 [110]3 years ago
5 0
When atoms combine to form a new substance, they are forming chemical bonds that bind them together. It is these bonds that define what is formed. The nature of the bond formed is dependent on the conditions in which the chemical reaction is taking place. For instance both diamond and graphite are made of carbon atoms

Imagine a genomic researcher who is analyzing the genome of different types of cats. She finds that a particular sequence in the
egoroff_w [7]

Answers:

  1. The sequence encodes a gene that is critical for life and cannot be easily mutated while retaining function.
  2. The sequence is contained in a retrovirus that has infected both species.

1- Explanation:

6.8 million years is a considerable period of time and if the cats were evolved in two different specie then technically they should have substantially different sequences of gene. However, there are some genes that are critical for the survival of the organisms because they encode a function which is equally important for the organisms of a certain category, even if they are different specie.

For example, the essential genes that are involved in maintenance of metabolism, initiation of replication or translation of genes. Therefore, with the period of time, the mutation of even a single nucleotide can be lethal for these genes, and if it happens organism will simply die. So, if one organisms is died that cannot take part in the process of evolution and would clearly be cut off from the process, However, those who survive can undergo some other mutations and become separate specie.

2- Explanation:

A retro virus inserts itself in to the genome of host organisms and become a part of them. It is very difficult to detect the presence of the retro virus until the organism undergoes infection due to its attack. Cats are a favorable host for retroviruses - called lentiviruses which attack the cats to cause a critical syndrome Feline Immunodeficiency Virus or FIV. Therefore, it is possible that same retrovirus having a particular sequence has attacked both cats and the sequences were taken from those cats.

List 3 factors that can speed up the rate of chemical reactions
zysi [14]

Answer:

  1. Temperature
  2. Greater Surface Area
  3. Catalysts

Explanation:

Temperature

  • An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision (Figure. 17.5 “Temperature and Reaction Rate”).

Greater Surface Area

  • The rate of a chemical reaction can be raised by increasing the surface area of a solid reactant. ... more particles are exposed to the other reactant. there are more collisions. the rate of reaction increases.

Catalysts

  • A catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process. Catalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism.

Hope this help!!!
