Darwin also observed fossil shells of marine organisms high up in the Andes mountains, and saw an earthquake move land that was underwater above sea level. How did he apply these insights to the evolution of organisms?
Answer:
Geological events can cause drastic changes over long periods of times
Explanation:
He used these insights and stated that Geological events can cause drastic changes over long periods of time. Such changes can cause entire species to become extinct or cause drastic evolutionary physical changes to other species. This is because the environment changes and the animals living in these environments need to adapt in order to be able to survive. Some changes such as continental drift can even move species to different parts of the world where the climate is drastically different.

If a DNA strand has a nucleotide sequence of CATGAGTTA, what will the mRNA strand be after transcription?
Answer:
leave the nucleus, goe to the cytoplasm,bind to a ribosome to be read
If a DNA strand has a nucleotide sequence of CATGAGTTA, the nucleotide sequence of the mRNA after transcription will be GUACUCAAU.
TRANSCRIPTION:Transcription is the process by which mRNA molecule is synthesized from a DNA template. In the transcription process, the complementary strand of the DNA is synthesized as the mRNA strand. This means that uracil will be synthesized from adenine and cytosine from guanine and vice versa. Therefore, if a DNA strand has a nucleotide sequence of CATGAGTTA, the nucleotide sequence of the mRNA after transcription will be GUACUCAAU.Learn more about transcription at: https://brainly.com/question/15175461?referrer=searchResults

QUE SON LA BIOMOLECULAS
Son consideradas biomoléculas aquellas moléculas que forman parte de los organismos vivos.
Las moléculas son las unidades físicas de la materia, que se forman a partir de la unión de dos o más átomos agrupados a través de enlaces químicos.
Las biomoléculas se clasifican en inorgánicas u orgánicas.
• Las biomoléculas inorgánicas se encuentran ampliamente en la atmósfera. El agua, algunas sales como el cloruro de sodio, y gases como el oxígeno, son ejemplos de biomoléculas inorgánicas.
• A las moléculas como azúcares, proteínas, combustibles, entre otras, las cuáles contienen átomos de carbono, hidrógeno, oxígeno y a veces nitrógeno se les llama moléculas orgánicas.
Cuando las moléculas orgánicas forman parte de la materia viva, se les conoce como biomoléculas orgánicas, las cuales incluyen fundamentalmente glúcidos, lípidos, proteínas y ácidos nucleicos.
Por lo tanto, podemos concluir que las moléculas (compuestos que se forman a partir de los elementos químicos) que se encuentran formando los seres vivos se conocen como biomoléculas y se clasifican en inorgánicas u orgánicas.

6. If you are given a piece of white marble and a piece of white quartzite what test can
you do to determine which is which? What results will you get?
Answer:
Quartzite is a metamorphic rock formed when quartz-rich sandstone or chert has been exposed to high temperatures and pressures. Such conditions fuse the quartz grains together forming a dense, hard, equigranular rock. The name quartzite implies not only a high degree of induration (hardness), but also a high quartz content. Quartzite generally comprises greater than 90% percent quartz, and some examples, containing up to 99% quartz, and are the largest and purest concentrations of silica in the Earth's crust. Although a quartz-rich sandstone can look similar to quartzite, a fresh broken surface of quartzite will show breakage across quartz grains, whereas the sandstone will break around quartz grains. Quartzite also tends to have a sugary appearance and glassy lustre. The variety of colours displayed by quartzite are a consequence of minor amounts of impurities being incorporated with the quartz during metamorphism. Although quartzite can sometimes appear superficially similar to marble, a piece of quartzite will not be able to be scratched by a metal blade, and quartzite will not fizz on contact with dilute hydrochloric acid.Explanation:

Alleles for curly-haired poodles are dominant over those for straight-haired poodles. A cross was performed between a curly-haired poodle with unknown genotype and a straight-haired poodle. The result produced all curly-haired poodles. Based on the information and probability of offspring genotypes, what was most likely the genotype of the curly-haired poodle
Answer:
The genotype of the unknown poodle it most likely Hh (let H stand for curly hair and h stand for straight hair).
Why are most genetic diseases caused by recessive alleles?
Answer:
Recessive disease mutations are much more common than those that are harmful even in a single copy, because such "dominant" mutations are more easily eliminated by natural selection.

For decades, scientists relied on the fossil record and comparative anatomy to assemble evolutionary lineages. Which statement describes a limitation of these methods? (1 point) They are no longer relevant because the fossil record is complete. They can show false relationships between organisms that are not reflected in the DNA. They are not reliable evidence of how the body structures of organisms evolved. They cannot be used to determine when species evolved.
Answer: They can show false relationships between organisms that are not reflected in the DNA
Explanation:
Okay so there is a thing called "convergent evolution" which basically means that different species coming from different evolutionary lines evolve the same traits. It's really easy to mistake convergent evolution for evolutionary similarities. From the fossil record, it's easy to see the bones of one animal and to see that they are similar to another but that doesn't prove that they are related because it's often due to convergent evolution.
They can offer false relationships between organisms that are not reflected in the DNA. Also, they don't prove they are related due to convergent evolution.
What is DNA?
There is a thing called "convergent evolution" which essentially suggests that additional species coming from different evolutionary strings become the same traits.
It's really easy to misunderstand convergent evolution for evolutionary parallels.
From the fossil record, it's easy to catch the bones of one animal and to see that they are equal to another but that doesn't confirm that they are connected because it's often due to concurrent evolution.

4. Which of the following is NOT a tenant of the Cell Theory?
a. All cells(come from existing cells.
b. All living things are made of cells.
C. Cells are the basic units of structure and function.
d. All cells contain a nucleus.
Answer: b. All living things are made of cells.
Explanation:
A cell is the smallest basic unit of life that is capable of independent functionality. A cell therefore cannot be made up of other cells because that would imply that there is a unit of life that is smaller than cells.
Cells are instead made up of organic molecules like protein and carbohydrates and when cells work together to achieve a common goal, they form a tissue. Tissues are the ones made up of cells not cells made up of other cells.

Dams without side channels interfere with fish needing to swim upstream to lay eggs for reproduction may not be able to get past the dams and young fish that are swimming downstream may be killed by the turbine blades. This has caused a severe decrease in sockeye salmon populations in areas of Northwest U.S.
All of these are some of the possible costs of hydroelectric power plants.
Sometimes a lot of water is released by a dam at a given time, resulting in flooding downstream. This affects both wildlife and drinking water. Flooding also often occurs during the construction of a dam as the reservoir fills in areas that were once above the water level forcing people and animals to relocate due to lost habitat.

Por que las hojas de la lechuga se ponen turgentes al dejarla en agua y luego al preparar la ensalda se arruga
Answer: Las células de la lechuga son hipertónicas al agua fresca (el agua entra en las células y se hinchan) pero hipotónicas a una solución salina (el agua sale de la célula y se arruga)
Explanation:
La lechuga (Lactuca sativa) es una planta de la familia Asteraceae, que se cultiva sobre todo como verdura de hoja para su consumo, aunque también se utilizan las semillas y el tallo. La lechuga se utiliza especialmente para las ensaladas, aunque también se ve en otros tipos de comida, como sopas o sándwiches.
Cuando la hoja de lechuga se deja en agua, dicha agua entra en las células mediante ósmosis, el cual es es un mecanismo de difusión pasiva en donde el agua se transporta a través de una membrana semipermeable yendo desde la región de mayor concentración al de menor concentración. Cuando se coloca una célula vegetal (en este caso de lechuga pero puede ser de cualquier vegetal) en una solución hipotónica, el agua se desplazará hacia las células vegetales y éstas se hincharán. Esto se debe a que una solución hipotónica es una solución que tiene una menor concentración de solutos en comparación con otra solución en el interior de la célula.
En el caso en el que se prepara una ensalada, las hojas de lechuga se arrugan porque al agregar sal, el medio se convierte en hipertónico y a través de ósmosis, el agua saldrá del interior de la célula y por ello, se arrugan. Hipertónico significa que el entorno exterior a la célula tiene una mayor concentración de solutos que la propia célula. Además, las células de la lechuga están cubiertas por una capa impermeable y esto evita que el agua salga de la célula al medio exterior y que la sal entre desde ese medio.
Entonces, las células de la lechuga son hipertónicas al agua fresca pero hipotónicas a una solución salina (agua con sal).
