Aerobic exercise is the body producing energy WITH the use of oxygen (light activities like jogging). Anaerobic exercise produce energy without the use of oxygen and is typically a higher intensity that burns fat AND helps gain lean muscle mass (these are activities like weight lifting).
Answer: Crossing-over allows the genes that come from each parent to recombine before they are passed on to future generations because chromatids of homologous chromosomes mate and exchange sections of their DNA.
Explanation:
Chromosome crossing-over is the process by which chromatids of homologous chromosomes mate and exchange sections of their DNA during prophase I of meiosis, when pairs of homologous chromosomes, or of the same type, are aligned. The chromatids of the homologous chromosomes break off in the chiasmas and rejoin to allow recombination of the linked genes. So it occurs when regions at chromosome breaks mate and then reconnect to the other chromosome. <u>The result of this process is an exchange of genes, called genetic recombination</u>.
This allows the genes that come from each parent to recombine before they are passed on to future generations. Then, <u>it is an important source of genetic variability</u>, since it involves an exchange of segments between homologous chromosomes during the development of gametes. <u>This process allows that the descendants of an individual are genetically very different</u>, since it is very unlikely that an individual produces two equal gametes, because all of them have different segments of the homologous chromosomes.
Answer:
Coal, oil, and natural gas are examples of fossil fuels.
Explanation:
We use things made from rocks and minerals every day. It is estimated that every person in the United States will use more than three million pounds of rocks, minerals and metals during their lifetime. 82,000 gallons of petroleum
Answer:
Its heavy bones helped in reduction buoyancy
Explanation:
Indohyus Is an extinct animal and fossil studies and records have been discovered about this animal. It is known to be like the size of a cat and it was discovered it was an animal which survive mainly on land but could also survive in water for a certain duration of time. It has heavy bones which reduced its buoyancy and helped it to hide from predators on land and made it to stay there for a long time without floating to the surface of the water bodies.
BTX or batrachotoxin is a type of steroidal alkaloid which was first derived from the skin of Dendrobatidae or poison dart frogs. This neurotoxin prevents the muscle and nerve cells from transmitting electrical signals. The toxin permanently blocks electrical signal transmission from the nerves to the muscle by binding and inactivating the sodium channels.
