youngest layers, and the bottom layers are the oldest
Which cross section could be used as evidence that, over time, a circular shellfish descended from a hexagonal shellfish?
1
2
3
Answer:
The answer is number 4
Explanation:
Cross section 4 contains evidence that a transition from a hexagonal shellfish to a more a rectangular shellfish and then to a circular shellfish may have occurred. These changes would have been gradual, as shown by the position of the fossils in each layer of the canyon.
Although the evidence provided by cross section 4 is strong, more research would be needed to prove a connection among the shellfish in the canyon, such as morphological or
The cross-section in diagram 4 could be used as evidence that, over time, a circular shellfish descended from a hexagonal shellfish. Hence, option D is correct.
What are fossils?Fossils are the remains or traces of ancient living organisms that have been preserved in sedimentary rocks or other materials over long periods of time. Fossils can include bones, teeth, shells, imprints, or other parts of plants and animals that have been mineralized, or turned into rock, over millions of years.
They are important clues to the history of life on Earth, providing evidence of the evolution of different species and the environmental conditions that existed in the past.
Fossils can be studied by paleontologists to learn more about the biology and ecology of ancient organisms, as well as to understand how the Earth's ecosystems have changed over time. Hence, option D is correct.

Explanation:
A model answer for translation is always this:
mRNA leaves the nucleus via the nuclear pores and travels to a ribosome (in the cytoplasm or on the rough endoplasmic reticulum)
The ribosome attaches to the start codon on the mRNA.
A tRNA molecule with an anticodon complementary to the start codon on the mRNA carries a specific amino acid to the ribosome and lines up against the mRNA codon.
This is repeated, and each tRNA molecule transports a unique amino acid to the ribosome until the stop codon on the mRNA strand is reached.
As the ribosome moves along the mRNA strand, peptide bonds form between the adjacent amino acids, forming a polypeptide chain.
This chain detaches from the ribosome and will undergo folding to become a specific type of protein.

why do you think slate might be denser then shale?
Answer:Slate is denser than shale because its atoms and molecules become more compact due to the presence of intense pressure. Due to this event, the minerals are squeezed and realigned in such a way that the axes are directed to where the pressure was applied.

There are several mechanisms through which reproductive isolation occurs. Which situation is an example of behavioral isolation?
A.
Mules, the offspring of a male donkey and a female horse, are unable to reproduce because they are sterile.
B.
Males of different, closely related species of fireflies signal for mates by flashing different light sequences.
C.
The reproductive organs of snails only properly align when the male and female belong to the same species.
D.
Red and purple sea urchins cannot reproduce with one another because the sperm and egg cannot fuse.
Answer: B. Males of different, closely related species of fireflies signal for mates by flashing different light sequences.
Reproductive isolation refers to the inability of the members of a species to breed with members of other species. Behavioral isolation is a type of reproductive isolation, in which mating between the members of the species is facilitated by their behavior. It helps members of the same species to identity their mates. It prevents mating between population of distinct species.
Males of different, closely related species of fireflies signal for mates by flashing different light sequences is an example of behavioral isolation because flashing of light by fireflies is the behavioral characteristic which shows their desire for mating. The mates identify the light signals flashed by their partner belonging to the same species.
Answer:
B. Males of different, closely related species of fireflies signal for mates by flashing different light sequences.

Which nation would be CLOSEST to the command side on this economic
continuum?
O the United States
O the United Kingdom
O France
O North Korea
Answer: D) North Korea
==============================================================
Explanation:
The United States, the United Kingdom, and France are all countries that have capitalistic economies. This means that (for the most part) private industry and the market determines what products are produced and who gets those products. I said "for the most part" because these countries don't follow a purely capitalistic structure. There are some elements of government regulation to ensure that no breakdowns occur. The regulations are also to ensure some level of fairness as well, in addition to preventing things like fraud.
On the other hand, countries like North Korea are known as command economies because the government determines what products are to be made and they determine who gets the products. This means that they set the prices as well to whatever they feel is correct (even if the market may disagree otherwise). The term "communism" is often strongly connected to the term "command economy".

What best describes the role of photosynthesis and respiration in the carbon cycle?
Answer:
Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.
Explanation:
Please mark me as brainlist
Photosynthesis removes carbon from the atmosphere, respiration adds carbon to the atmosphere.
What is photosynthesis?Photosynthesis is defined as the process through which plants convert carbon dioxide, water, and sunshine into oxygen and sugar for energy.
It can also be defined as a method used by plants and other living things to change light energy into chemical energy that can then be released through cellular respiration to power the organism's activities.
Through photosynthesis, plants transport carbon from the atmosphere into the biosphere and up the food chain. They use solar energy to chemically combine carbon dioxide, oxygen, and hydrogen from water to create sugar molecules.
Photosynthesis is primarily used to convert solar energy into chemical energy, which is then stored for use at a later time.
Thus, photosynthesis removes carbon from the atmosphere, respiration adds carbon to the atmosphere.

A student wanted to compare germinating pea seeds (growing) and nongerminating pea seeds
(not growing). She wanted to test two variables: germinating vs nongerminating peas at two
different temperatures: 10° C and 25° C.
The student proceeded to set up two electronic water baths: a warm water bath (25° C) and a
cold water bath (10°C). She also set up four respirometers: two containing germinating peas
and two containing non-germinating peas. Where would she need to place the respirometers in
terms of water baths to ensure that she was setting up a controlled experiment?

Cómo los avances de la ciencia y la tecnología sin control puede llegar a afectar al ser humano, demás seres vivos y el entorno.
Answer:
nuevas tecnologías y desarrollos científicos muchas veces conllevan un potencial para generar daños irreversibles sobre las poblaciones humanas y el medio ambiente
Explanation:
Los avances científicos y tecnológicos conllevan grandes ventajas para la humanidad y simultáneamente también riegos que pueden producir daños irreparables en las sociedades y el medio que las rodea. Por ejemplo, el dominio de la tecnología basada en el uso de la fisión nuclear ha sido beneficioso para obtener grandes cantidades de energía, pero también este desarrollo conlleva la producción de armamento nuclear que pone en riesgo a las sociedades y al medio ambiente. Otro ejemplo puede estar representado por el uso de la tecnología de edición genómica CRISPR-Cas, la cual ha sido recientemente desarrollada. Esta tecnología ha llevado esperanza para el tratamiento de enfermedades genéticas hereditarias a través de la restauración de la función génica. Sin embargo, la técnica CRISPR-Cas de edición genómica ha sido recientemente utilizada para desarrollar bebés editados genéticamente, aún cuando los efectos secundarios que dicha tecnología no han sido completamente resueltos (efectos de edición genómica en regiones genómicas no deseadas), con lo cual llevando un serio riesgo para los bebés que han sido modificados genéticamente. De este modo, cada avance científico tecnológico debe estar apropiadamente regulado por las sociedades a fin de evitar los potenciales efectos dañinos de dichos avances.
