The fossil symbols and mountain belts were helpful because it showed where the land and water dinosaurs were able to live, especially with the non-swimmers in Africa and South America. There is proof of some mountains matching in Western Europe and Greenland.
When the human body (its cells) is exposed to radiation (X rays and gamma rays), electrons are emitted from atoms and molecules. ... ・These radicals react immediately with surrounding atoms, causing abnormal chemical reactions (or, minor damage to localized areas of cells).
Answer: The way an author describes or conveys a character’s traits.
Explanation:
Sensory neurons and motor neurons are only two of the basic types of neurons. The basic function of neurons are in transmitting nerve impulses to the different parts of our body. Sensory neurons<span> carry signals from peripheral parts of our body into the central nervous system. On the other hand, m</span>otor neurons<span> carry impulses from the central nervous system to the peripheral parts of our body.
Best answer: </span><span>sensory neurons carry stimuli information to the brain; motor neurons carry processed information to muscles and glands. </span>
Answer:
Because of homologous recombination
Explanation:
- When genes are establish on different DNAs or far apart on the same chromosome, they are classified self-sufficiently and are said to be unlinked.
- When genes are very close together on the same chromosome, they are said to be linked. That means that alleles, or genetic versions, that are already together on a chromosome will be inherited as a unit more often than not.
- We can see if two genes are linked, and how closely, by using data from genetic crosses to calculate the frequency of recombination.
- Using the technique of discovery recombination happenings for numerous gene pairs, we can make link maps that show the order and relative distances of the genes on the chromosome.
- When the genes are on the same chromosome but far apart, they are classified independently due to crossing (homologous recombination). This is a procedure that happens at the start of meiosis, in which homologous DNAs randomly exchange matching fragments. Crossing be able to connection new alleles in combination on the same chromosome, causing them to enter the same gamete. When the genes are far apart, the crossing occurs with sufficient frequency for all types of gametes to occur with 25% percentage frequency.
- When the genes are very close together on the same chromosome, the crossing still occurs, but the result (in terms of the types of gametes produced) is different. Instead of being classified independently, genes tend to "stay together" during meiosis. That is, alleles of genes that are already together on a chromosome will tend to pass as a unit to gametes. In this case, the genes are linked
