Answer:
for a fossil to form, an organism must be buried quickly so that any oxygen is cut off and its decay slows down or stops. ... Fossil formation begins when an organism or part of an organism falls into soft sediment, such as mud.
Explanation:
Answer:
The correct answer will be-
1. Chromosomes are made up of protein and nucleic acid.
2. Genes are located on chromosomes.
3. Chromosomes are found in the nucleus.
Explanation:
Watson and Crick are known for their findings on the structure of DNA in 1953. Their findings were motivated by the book called "What is Life?".
The book stated the concepts which were well accepted by the scientific communities that is the gene determines the trait which is located on the chromosomes proved by the experiments of Morgan.
The chromosomes are the condensed structure present in the nucleus was suggested by the Nageli in 1884. The chromosomes are composed of nucleic acid and protein was also proved and was well-accepted fact.
But the genes are made up of DNA was not well accepted which was suggested by the experiments of Avery in 1940s.
Thus, the selected options are the correct answer.
Answer:
The correct answer is - the hypothalamus.
Explanation:
The generation of action potentials or nerve impulses generated in the neurons within the hypothalamus which result in the secretion of the hormones.
Hypothalamus is the part of the brain that plays many roles in the body including homeostasis by the secretion of the hormones which are released due to the nerve impulses generated in the nerves present within the hypothalamus.
La teoría de la evolución de Lamarck se basa en la capacidad de los organismos para cambiar físicamente debido a las adaptaciones en su entorno para garantizar su supervivencia. Esto es evidente en la propagación de los determinantes de resistencia a los antibióticos entre las bacterias. La capacidad de las bacterias para desarrollar nuevos mecanismos de resistencia para sobrevivir a los antibióticos radica en su capacidad para adquirir genes que los ayuden a este respecto a través de la transferencia horizontal de genes y la adquisición de plásmidos. Mecanismos como bombas de eflujo y plásmidos les ayudan a sobrevivir en medio de antibióticos. Transmiten estos materiales genéticos a sus descendientes, lo que garantiza que continúen sobreviviendo y no se extingan a pesar de la presencia de antibióticos.
El dawrnismo claramente reclama la selección natural. Por lo tanto, si un organismo no evoluciona o adquiere características especiales para ayudarlo a adaptarse, competir y sobrevivir en su entorno, se extingue. Solo aquellos que adquieren estas habilidades sobreviven y se reproducen en el medio ambiente.
Autotrophs make their own food from the sun so most energy starts there
